Consumer Law Essay Example

Consumer Law Essay The most useful dictionary definition of a consumer is someone who buys goods and services for personal use or need (Chambers 21st Century Dictionary). All consumer transactions are based on the law of contract. The consumer agrees to purchase goods or services and the seller in return provide those goods or services. Every exchange of goods is an agreement between the buyer and seller thus making them based on the law of contact. The major act that supports and assists consumers is the Sale of Goods Act 1979 (SGA), as amended by the Sale and Supply of Goods Act 1994 and Supply of Goods to Consumers Regulations 2002. The Sale of Goods Act covers transactions where goods are transferred for monetary consideration, called the price(Nutshells p. 1). In the course of this essay I will be looking at the relevant Acts in order to establish how the law seeks to protect the consumer. In the light of the question, by looking at the useful dictionary definition and the definition provided by the relevant statutes, which states that a consumer is a natural person entering into a contract with another in the course of business we can see that Lil clearly fits the definition of a consumer by meeting both the definitions set out.

This phrase can be used in both civil and criminal law and the courts in relation have tried to keep the meaning same across both sections, RB Customs Brokers Co Ltd v. united Dominion Trust Ltd (a civil case) which followed the guidance in Davies v. Summer (a criminal case). In relation to our scenario as the goods, which in this case is the shoes, are transferred for a monetary consideration, the sale is governed by the Sale of Goods Act 1979. Under this Act the implied terms set out by S. 14 only apply when the goods are sold in the course of business with the transaction being an integral part of the business, with some degree of regularity and in the nature of trade and carried out with a view to making a profit, this can be seen in the case of Stevenson v. Rogers (1999). This section does not cover any private sales and there is an exception where the sale is carried out as a hobby, with no significant profit being made. In the light of our scenario we can clearly name Tuffstuff as the seller and acting in the course of business because the goods (shoes) where sold within the store where transaction is an integral part of their business. There is a degree of regularity because they are constantly in the course of business selling shoes thus being in the nature of trade with a view to making profit from their sales. Now that I have identified the parties to the valid contract I will be looking at the terms implied by the Sale of Goods Act 1979. Sections 12,13,14 and 15 of this Act imply terms into contracts for the sale of goods. The essential issue here is whether the goods (shoes) where fit for their purpose. Section 14 (3) of the SGA 1979 states that the seller sells goods any particular purpose for which such goods are commonly supplied (P. 11 Unit Guide). By using and applying this rule to the facts of the case we can see that purpose of the goods are essential. This is to say whether or not the purpose is one for which such goods are commonly supplied and used for or one that the consumer has used it for. The purpose could be made known by implication where the purposes of the goods in question are obvious, e. . a hot water bottle in the case of Preist v. Last 1903 (Consumer Law P. 45). In relation to our case facts we do not know what kind of shop the consumer brought the shoes from or the type of shoes theyve brought in detail, we can only rely on the statement made by the shop manager which states that the shoes were not intended for use on rugged terrain. It is stated that consumers frequently buy one-purpose goods where no advice is taken from the seller regarding the goods because the purpose is implied being only one-purpose goods hence breaching S. 14 (2) and 14(3) if the goods are defective. In relation to multi-purpose goods the buyer is advised to ask as many questions as possible about the goods and what they can use it for in order to benefit under S. 14 (3). This can be seen in the case of Griffiths v. Peter Conway Ltd 1939 where the buyers skin condition was not communicated to the seller thus there was no breach of S. 14 (2) or S. 14 (3). If in cases such as this the buyer does not communicate what they intend to use the goods for, other then their normal purpose, then the extent of the sellers obligation is to ensure that the goods are fit for what their original purpose is for (Jewson Ltd v. Kelly 2003). In the light of our scenario we can see that the consumer used the shoes on a hill-walking holiday. The shoes are one-purpose goods and are not intended for specifically to be used on rugged terrain, as the retailer reasonably assumed. There was no communication between Lil and the seller prior to the sale regarding if the shoes could be used for hill-walking, if however Lil asked many questions and gathered information regarding the goods then she could have got the maximum benefit under S. 14 (3). Section. 14 SGA implies that goods must be of satisfactory quality. In order to advise Lil on her contractual rights it is vital to understand this section of the Act. To begin with, the topic here regards the quality and fitness of the product in concern. Section. 14 (2) states that Where the seller sells goods. supplied are of satisfactory quality. In order to move on we must understand what satisfactory quality means. Before 1994 the test was to see if the goods were of merchantable quality. This was later replaced by the test of satisfactory quality. The need for this change was highlighted in the case of Bernstein v. Pamson Motors (1987) (Consumer Law P. 45). The wording of the SGA 1979 was amended with the passing of SGA Amendment Act 1979 which now states that goods are of satisfactory quality if they meet the standard that a reasonable person would regard as satisfactory (P. 11 Unit Guide) taking account of any description of the goods, the price and all other relevant circumstances (s. 14 (2a)). Also s. 14 (2b) states that quality of goods include their state or condition and 5 other points (A. Fitness for all commonly supplied, B. appearance and finish, C. freedom from minor defects, D. safety and E. durability (P. 11 Unit Guide)). In the light of our case points A, D and possibly E clearly apply as relevant and need to be considered because the other 2 quality points can be seen as fulfilled by the seller. The shoes purchased by the consumer were not durable and had fallen apart making them unwearable which could be unsafe for the consumer. The fact that the shoes were not durable could mea n they are not of satisfactory quality under the SGA 1979. The case of Bernstein v. Pamson Motors (1987) could be useful under the durability section. The question we need to ask is how long we expect new goods to last? From the Act this is hard to figure out because the definition states durability is a factor but does not give any further information so it is useful to look at the facts of each case in order to determine durability of new goods. In the Bernstein case Rougier J. held that the car brought was not merchantable quality because you would expect buying a new car the engine would not seize up after three weeks. In todays case the car would not be one of satisfactory quality. Before we come to a solid conclusion regarding Lils contractual rights and any remedies, which may exist, another issue raises. Terms in S. 13, 14 (2) and 14 (3) are all conditions. Their importance is vital as buyers are concerned because they can affect the remedies they can pursue. However S. 11 (4) of the SGA points out that where a contract of sale is not severable to be treated as a breach of warranty (Nutshells P. 14). The issue is whether there is evidence of acceptance of the goods, which affects the type of remedy the consumer, is entitled to claim. Sections 34 and 35 of the SGA administrate acceptance and S. 35 declare that acceptance can occur in three ways. 1) By intimation to the seller that is to say verbally notifying the seller that you accept the good 2) by an act after delivery inconsistent with the sellers ownership 3) via retention beyond a reasonable time (Consumer Law and Practice P. 110-12). In connection with our scenario the final method of acceptance (number 3) is decisive. The question we need to ask is when does the time start to run and what is considered to be reasonable? The fundamental case of Bernstein v Pamson Motors (1987) where it was held keeping the car in question for three weeks constituted to acceptance, which meant the consumer, was entitled to an equitable remedy only (Nutshells P. 15). However this case was seen not to be advantageous to consumers and the amendments mean that the law is now more in favour of the consumer. The Court of Appeal recently held that Bernstein was no longer good law. In the case of Clegg v. Olle Andersson (2003) the aim behind S. 5 (5) had been achieved and that the buyer could reject his yacht even after seven months (Consumer Law and Practice P. 113) Nevertheless having possession of goods beyond reasonable period of time still constitutes acceptance but reasonableness is a question of fact and the issue of having reasonable time to examine the goods must be considered. In relation to our scenario and the case facts the question we need to ask is whether Lils holiday is reasonable time for acceptance and reas onable time to examine the goods? The facts of the cases are very special in order to come to a conclusion. In tradition a problem like this is unlikely to arise because Lil will have a right of repair or replacement under the 2002 Regulations or, if this is not achievable, a suitable degree of reduction in the price she has paid. By looking at the case facts it could be said that Lil wore the shoes through out the holiday, even though clearly the shoes were not fit for the purpose of hill walking. This could be seen as her accepting the shoes. If after wearing the shoes Lil had realised that they were falling apart and not worn them again then she would argue that she has not accepted the goods and could reject the shoes. We have not been told how long the holiday has been for, and the fact that she has worn the shoes through out the hill-walking holiday till the end, I believe, constitutes to Lil accepting the goods. This is to say that the term under S. 14 (3) SGA is no longer a condition and is now to be treated as a warranty only. This is governed under S. 11 (4) SGA, which provides where a contract of sale is not severable and the buyer has accepted the goods the breach of any condition is to be treated as a warranty (Nutshells P. 14). Lil has accepted the goods so damages are the only remedy. The case of Hadley v. Baxendale (1854) and Sections 51 to 53 SGA set out the details of the kind of damages that Lil can claim. In cases such as this most retailers offer a replacement, but because in this case Tuffstuff no longer stock the same type of shoe, then the other remedy of repair will be available. She will be entitled to damages for breach of warranty for the product S. 53 SGA. In this case it will be the cost of putting the goods right and any inconvenience of not having the goods (distress) that it may have caused. Repair of the goods is therefore the most likely and logical outcome of this case. In connection to the alleged exclusion liability clause printed on the receipt the first point that needs to be considered is whether or not, by the common law rules, the clauses have been incorporated in the contract. First of all the type of document involved is important. In the case of Chapelton v. Barry UDC (1940) a receipt could not be expected to contain vitally important exclusion clauses and it was held that there was no incorporation. In the light of our scenario we can se that the exclusion of liability is printed on the reverse of the receipt, which was handed to Lil when she brought the shoes. Also from the facts we can see that reasonable steps werent taken to bring the notice before Lil prior to the contract is made. In the light of this argument the exclusion liability will not be incorporated into the contract. However we are not aware, from the case facts, what the exclusion liability is or how vitally important it is. If the exclusion liablilty appears to be incorporated into the contract, being not vitally important, then it will be governed by UCTA (Unfair Contract Terms Act 1977). The clause printed is trying to exclude liability. Any clause, which is trying to do this, with the effect of UCTA S. 6, will be deemed as void when the buyer is dealing as a consumer (P. 20-4 Unit Guide). The question now is whether Lil was dealing as a consumer? Again by S. 6 of UCTA a person deals as a consumer when s/he buys from someone acting in the course of business where the buyer holds himself or herself as just a private buyer and not acting in the course of a business. From the case we can clearly see that Lil is a consumer thus making the exclusion of liability void. In addition, Consumer Transactions Order 1976 states that, a trader can be guilty of a criminal offence where they exhibit a void exclusion clause in a notice, or in this case on a till receipt. Tuffstuff therefore could be guilty of a criminal offence. Overall because acceptance has occurred by Lil the condition by S. 11 (4) of the SGA becomes a warranty for which only the damages that I have set out above could be claimed.

Drugs, Alcohol, Stimulants, Depressants and Theories Essay Example

Drugs, Alcohol, Stimulants, Depressants and Theories Essay Example Drugs, Alcohol, Stimulants, Depressants and Theories Paper Drugs, Alcohol, Stimulants, Depressants and Theories Paper Stimulants are those drugs that provisionally amplify attentiveness and consciousness. They typically have amplified side-effects with augmented efficiency, and the prevailing alternatives are consequently often drug remedies or prohibited drugs. Stimulant drugs boost the doings of neither the central nervous system, sensitive nervous system nor both. Several stimulants generate a feeling of exhilaration, particularly those stimulants that put forth influence on the central nervous system. Stimulant drugs are therapeutically used to boost or sustain attentiveness, to work against fatigue in circumstances where slumber is not convenient, to thwart irregular states that reduce attentiveness perception, to uphold weight loss and to augment legally the capability to contemplate in individuals with attentional disruptions for instance ADHD (CherlandFitzpatrick 1999, p811). Sporadically, stimulants are used to manage depression as well. Stimulant drugs are at times used to increase stamina and efficiency and to repress hunger, consequently also identified to promote eating abnormality like anorexia if ill-treated. The elation created by several stimulants makes recreational purposes, even though this is against the law within major authorities. Caffeine is found in tobacco as well as nicotine, which is also found in beverages such as soft drinks and coffee, are amid some of the most frequently used stimulant drugs. Recognized stimulants comprise amphetamines, ephedrine, cocaine, modafinil, methylphenidate and MDMA. A stimulant drug is usually referred in jargon as the ‘upper’. These drugs with considerable misuse potential are extremely cautiously controlled substances. Some are legally available merely by recommendation (mixed amphetamine salts, methamphetamine, Dexedrine, dexamphetamine, Adderall. Phenethylamine is a monoamine and alkaloid and it is understood to be a neurotransmitter or neuromodulator. Additionally it is the fundamental chemical composition behind the majority of stimulants, particularly the sympathomimetic amine. The term ‘downer’ talks about the whole class of drug recognized as Depressant Drugs. Depressants are chemical drugs which slow down, or hold back, the performance of brain as well as central nervous system. Though several downers are obtainable nowadays, all plunge to one of the two major classes: sedative-hypnotics and tranquilizers. Tranquilizers are drugs that basically anesthetize, or decrease emotional as well as physical tension. The Sedative-hypnotic drugs take things a further step and provoke sleep. A widespread term for the sedative-hypnotics is the sleeping pills. Generally, the temporary effects of depressants are comparable. Major effects take account of augmented muscular repose and reduced nervousness. During the practice, they reduce self-consciousness, slow spontaneous effects, and damage dexterity. Along the negative aspect, depressants have also a propensity for tedious judgment, decrease opinion, and hinder recollection, responsibilities at work, on the road, or further settings that require clear judgment as well as prompt reactions. To the extent that they are comparable, depressants are still different; predominantly in the system they attain their effects. Broadly used as a sleeping pill, the barbiturate (Seconal, Tuinal,) is as obtainable as legal drugs might be. The most accepted sleeping pill and non-barbiturate is Halcion but Halcion has a negative aspect for it abates quickly that several users have apprehension as the drugs outcomes weaken. Abnormal reactions regarding Halcion were reported including hallucinations, amnesia, and violent behavior. In its legal use, tranquilizers, as depressants, are used to lessen delusions, hallucinations, as well as the intensity of rigorous cognitive-affective illness like schizophrenia. Given that main tranquilizers do not generate effects that people experience as gratifying, they are infrequently mistreated. On the contrary, the minor tranquilizers are the big issues. What people are currently ‘into’ is a set of drugs medically known as anxiolytic (anxiety-reducing); major types consist of meprobamate, benzodiazepine (BZD), as well as the painkilling antihistamines. Addictive Drugs: Tobacco, Caffeine and Alcohol Tobacco is widely known as an addictive drug. In general, smoking a cigarette is the initial group-shared drug occurrence, or the first illegal drug occurrence, akin to the use of Marijuana as it’s frequently unseen and outside the family as well as common societal approval values. Smoking can assist drug use afterward through teaching how to acutely breathe in and hold the smoke within the lungs thus cigarettes or tobacco, as smoked drugs, instigate teens into the feeling of gasping a drug as well as desensitize to a sensation of smoke entering into the lungs used for hashish, marijuana, or crack cocaine. The extent of tobacco use is openly associated to several drug uses; decades ago, tobacco companies disclose that if they take away the nicotine addictive element, people will stop buying tobacco products. Caffeine is actually the most established drug and it is within teas, colas, coffees, chocolates, as well as other various things. Caffeine is thus an addictive drug for the reason that functions on our brain, by means of identical mechanisms as cocaine, amphetamines, as well as heroin to rouse our mind. Though it is considered milder than others, caffeine is maneuvering very similar channels therefore it is addictive. Caffeine is in fact the trimethylxanthine having the chemical formula of C8H10N402. When secluded in uncontaminated structure, caffeine is a colorless crystalline particle with pungent taste. Physicians make use of it as cardiac stimulants and as mild diuretics (augment urine production). However usual folks endure it for â€Å"boost of energy† or sensation of sharp attentiveness it provides; it is frequently used to make individuals to be awake longer. Perceptibly, what is occurs is that our body becomes exhausted and requires rest; however, it is fluffed up instead to action. Our body, constantly pushed to greater action when it needs to stop to relax, is slowly dented. Rather than recovering, the organs of our body increasingly deteriorate and ultimately, the weak ones turn out to be unhealthy. Naturally, Caffeine is found in numerous plants, counting cocoa nuts, coffee beans, and tea leaves. As a result of this, it is established in an extensive multiplicity of foods. Additionally, caffeine is included as well in beverages. As the body turns out to be exhausted, the adenosine is manufactured within the brain, and then it binds to the adenosine receptor; this generates sleepiness through slowing the nerve cell activities. Moreover, the adenosine in our brain causes blood vessels to enlarge consequently further oxygen can arrive at the brain throughout sleeping. For the reason that the existence of caffeine is 6 hours, by the instance we get into bed, we cannot be asleep or we will not get hold of a deep sleep we necessitate; if the last cup of coffee was taken at 3pm, thus by 9pm, we still have 100mg in our body. as a result we feel inferior the following morning and we call for caffeine to be up and doing. Alcohol is an exceedingly addictive drug and it is thus categorized as a depressant drug, for the reason that it will slow down our body as well as our mind. A different way to explain it is that alcohol causes sedation, relaxation, and if an adequate quantity is devoured, the consequence will possibly be coma or even death. Judgment and way of thinking are two of the very important personality transformations that take place. The concentration of which is actually dose-related. The momentum of alcohol absorption has an effect on the speed at which one turns out to be drunk. Different from foods, alcohol does not require being unhurriedly absorbed. It is absorbed instantaneously to out blood, directly having passed within and through the walls of our appetite and frequently in our small intestines and the blood speedily conveys it to our brain (Blum 1991, p15). As an individual drinks quicker than an alcohol can be eradicated, the drug mounts up in our body, ensuing in higher quantities of alcohol within our blood. Alcohol is also burned, metabolized, as well as broken down in our body at a rather steady rate; the time-span for alcohol metabolism have an effect on the pace when one happens to be temperate all over again. Drug Abuse: Theories of Anomie, Differential Association and Social Control Anomie Theory drug use along with mistreatment are societal incidents subject to the clarity and response of the society. There is insight within the disputes of sociologists that societal evils, counting drug addiction, are communally created. Robert Merton defined Anomie as a collapse within the cultural formation, predominantly occurring when there’s a severe disjunction connecting the cultural goals and norms as well as the publicly controlled capabilities of the members of a group to do something in agreement with them. The conduct of an addicted person is complicated from several perceptions; it causes a noticeable challenge to an individual eager to stop but powerless to end it. Addiction commences in consumption manners the notion of deviance and habit: consequently the growth of customs, at social and individual plane, with the cognitive system where they depend on should be considered. A person is not located in a vacuity but she/he acts within specific framework, with informal and formal regulations. Cognition takes place from the individual within this structure and awareness has an important function in the creation of genuine models of manners that may perhaps be rather dissimilar among people. Differential Association Edwin Sutherland proposed this theory explaining that by means of interaction with other people, human beings gain knowledge of the attitudes, values, strategies, as well as motives for illegal manners. This assumption claims that unlawful actions are learned manners and learned by way of social relations with other people. It socially grows for people to make an offense, thus to become addicted to drugs. Differential association envisages that a person will prefer to become addicted to drugs when the equilibrium of classifications for misdemeanor goes beyond those for the obedient. This propensity will be toughened if the social connection provides dynamic individuals in the person’s existence. The person, earlier in his/her life, comes under the pressure of those with high status in a group; the further expected the person to pursue in their path. This doesn’t refute that there may possibly be realistic reasons for misdeed. If an individual is starving but without money, there are persuasions to steal however, uses of ‘values’ as well as ‘needs’ are undecided. To a lesser or greater point, criminal and non-criminal people are provoked by the necessity for money as well as public gain. Social Control Theory Travis Hirschi puts forward that peoples beliefs, relations, values, commitments, and norms persuade them not to follow the laws. Consequently, if the ethical codes are realized and people are attached to, and comprise a chance in a wider society, they are willing to limit their tendency for making deviant deeds. The premise aims to comprehend the customs wherein it is probable to decrease the probability of illegal drug use developing in people. It doesn’t mull over motivational concerns, basically claiming that people may prefer to employ in an extensive variety of activities, except that the range is restricted by routes of social learning as well as socialization (Thombs 1994, p27). Furthermore, Hirschi stressed that immoral groups would have no undeviating effect on criminal behavior when communal bonds restraining misbehavior were considered. He disputed that correspondingly uncommitted youth flowed mutually into groups against the law for the reason that weak societal bonds failed to put off relationship with delinquents along with criminal behavior itself. Groups that reinforce bonds were family, constructive groups, spiritual institutions, school, and so forth. This bond has 4 elements (a) connection (parents, school, peers), (b) dedication to conservative actions, (c) participation in accepted activities and (d) conviction in ordinary values. Social Control Theory highlights the reasonableness in the choice whether to connect in crimes and claimed that individuals were less expected to prefer crime if they have strong social bonds. By means of not intentionally disciplined traits and delinquency or unlawful acts independently, it recommends that concepts on low discipline and tendency for illegal deeds are no different.

Investment Basics Essay Example | Topics and Well Written Essays - 750 words

Investment Basics - Essay Example Creating portfolio involved asset allocation, asset selection decision, and asset execution. In asset allocation, the investors will decide on what marketable securities will he be investing, either in equities, fixed-income securities, and real assets (physical or identifiable assets). After the allocation, investors need to select on what are his asset preferences between stocks, bonds, and many more. The selection will be followed by the execution of investment portfolio and investment strategy. The final part of the process is performance evaluation wherein investment is constantly monitored by the investors themselves or through a portfolio manager. The Four Investments for Consideration in any Investment Portfolio Bonds (Municipal & Corporate). It is a debt instrument with specific return, interest and principal, and maturity date (Brigham & Ehrhardt, 2008, p. 157). Municipal bonds are debt securities issued by the government level whose maturity date is in a long-term basis. T hese bonds are considered to be secured and these are issued in order to support government operations and projects for the common good. Municipal bonds are known to be tax-exempt but it depends upon the purpose and jurisdiction. Corporate bonds are debt securities issued by corporations or business firms to finance variety of private purposes. These bonds are subject to a much higher interest rate for it is a risky investment (Brigham & Houston, 2009, p. 196). Stocks (Common and Preferred). These are issued securities that represent ownership. Ownership through the purchased of stocks are called stockholders which these are represented by stock certificates. Usually, stock prices of companies who are financially stable are high compared to those who are poor in performance because the higher is the value of the stocks the greater is the return of investment. There are two types of stocks, the common and the preferred stocks. In terms of the declaration of dividend and bankruptcy, p referred stockholders are satisfied first before the common shareholders (Investors Business Daily, 1996, p. 36). Both stocks running after income, the only difference is the risk involved. Preferred stocks are less risky but the growth income is fairly dependable while common stocks assumed higher risk but unlimited growth in income and capital gain (Rini, 2003, p. 33). Mutual Funds. It is an investment that used money â€Å"from a group of people with common investment goals to buy securities such as stocks, bond, money market instruments, a combination of these investments, or other funds† (Mobius, 2007, p. 3). These groups of investment securities are put together in a portfolio and it is appropriately managed by a portfolio manager. More often, investors prefer to invest in mutual funds because of access to a diversified portfolio, liquidity, and expertise by professional fund managers; however, mutual funds shared almost the same risk with investment in individual stock s, and drawbacks are always present. Derivatives. It is a financial instruments based on financial measurement of other assets that usually comes in contracts (Bragg, 2002, p. 156). Some of derivative instruments are forward, future, options, and swaps. The value of derivatives is based on the prices of some underlying assets or instruments. It also involved contracts between a seller and a buyer wherein the value is based on bargaining power (Rezaee, 20001, p. 390). Risk

The Expansion Strategy of Jumeirah Group of the Hotel Literature review

The Expansion Strategy of Jumeirah Group of the Hotel - Literature review Example A company may grow internationally through setting up new enterprises to a new area that has not been tapped, through buying off a company or integrating with an existing company (Marcelo at el 2008, P.1). Traveling for leisure of business mostly involves crossing national and state boundaries (Prokkola 2010, P.223) and tourism and hotel services provider must tap into providing competitive services and products to the visitor traveling to their company. Jumeirah Group is a multinational company that operates luxurious hotels and serviced apartments in Dubai, Rome, and Shanghai, Germany among other places in the world and its headquarters in Dubai (Newswire, 2012). The company was found in 1997 and is affiliated to Dubai Holding (Hornett, G 2013). The company is planning to grow its operation by establishing five-star luxury hotels in various countries in Africa one of them being Seychelles. Seychelles is a group of about 115 granite and coral tropical island in the Indian Ocean (Bac kground Note: Seychelles 2007). Its temperatures vary all around the year though they are humid due to their size. Most people occupy Major Island while small islands are sparsely occupied, with most of the residents being Africans, Indians, Chinese and French settlers while others are expatriates (Political Conditions 2012, P. 10). Their culture is a mixture of French and Africa through the most used language is English and French. This paper will critically analyze the expansion strategy of the Jumeirah group of hotel in this island nation. Feasibility analysis Indian Ocean islands depend on tourism as main economic activities with Seychelles and Maldives being the most preferred than the rest in terms of gross domestic product, employment, tourism income and tourism ventures investments (Prayag 2011, P.221). For example in 2010 tourism contributed to the Gross domestic product of this islands as follows Mauritius 26.5 %, Reunion 4 % in Madagascan 12.7 % % Maldives 63.4 % and Seyc helles 46.4 % while it also contributed to the national employment about 14.2 % of the total new appointment in Mauritius, 1.9 % in Reunion,3% in Madagascan, 28.1% in the Maldives and 31.5 %Seychelles (Prayag 2011, P.223). In recent times Indian Ocean islands have recorded increase in tourism activities due to their favorable climate, geographical isolation, relatively long coastlines, diversity of ecosystems, cultural diversity and political stability (Prayag 2011, P.223). However, there have been challenges in this industry such as poor working conditions for the employees, high staff turnover, environmental degradation, poor staff training and insufficient rules and regulations (Prayag 2011, P.223). Major islands in the Indian Ocean that include Mauritius, Reunion, Madagascar, and Seychelles have teamed up to Form Vanilla islands to market their countries as the tourist destination with the aim of increasing visitors (Ramchurn 2011, P. 49).

American Slavery 1606-1775 Essay Example | Topics and Well Written Essays - 1000 words

American Slavery 1606-1775 - Essay Example However, this also suggests that slavery was an important institution within the colonies long before the need for outside support was necessary. â€Å"Unquestionably it was a demand for labor which dragged the Negro to American shores, but the status which he acquired here cannot be explained by reference to that economic motive. Long before black labor was as economically important as unfree white labor, the Negro had been consigned to a special discriminatory status which mirrored the social discrimination Englishmen practiced against him.†2 This treatment of the black individual within the new continent began with the Spanish, expanded to the colonies as the native populations began dying out and became increasingly abhorrent in regards to denying human rights as the nation moved toward Revolutionary War. Initially, when the Spanish controlled the Caribbean islands, their interests were only in the mining of silver and gold. When the riches of the mines had been exhausted, the search for additional wealth moved inland and the Spaniards adopted a plantation based economy.3 Products from the Americas such as tobacco, cotton, cocoa and sugar were becoming increasingly popular in Europe which caused the Caribbean plantations growing these commodities to grow accordingly. The shortage of man-power to operate these ever-growing plantations required many numbers of slaves from Africa to be imported. As the Spaniards were reaping the rewards from its colonization of the Americas, their need for additional labor in the mines and plantations continued to grow. However, the local population was dwindling with the influx of disease and abuse and this, combined with Spain abolishing the enslavement of natives in the Americas in the mid 1500’s, necessitated a need to acquire Africans to fil l their labor requirements.4 In the initial phase of slavery in the

Biogeography Essay Questions

Biogeography Essay Questions 8 Biogeography Essay Questions 1.) What is the science of biogeography? Biogeography is that study of geographical distribution of flora and fauna considering the different taxonomic levels, present and past, the habitats in which they are found together with the involved ecological relationships. Today, there are two theories in biogeography that have been developed to discuss more on the distribution of biological species in the world. The two of them are Distance-decay and Island biogeography theories. The distance-decay theory asserts that the correlation and similarity between species in any two geographical locations will continue decreasing as the distance between the two increases. The second biogeographical theory, island biogeography asserts that those pockets of life (islands) that are closely spaced will support more biological life/species. It is still this second theory that explains that these closely spaced islands are rarely threatened by extinction if compared to the tiny isolated islands of the world. The Geographic Information Systems Scientists say that the above two theories were developed in order for us to be able to fully understand the distribution of species but not the distribution or even movement of human beings. As it was developed, the science of biogeography was meant to answer so many questions that are varied. It was developed so that it can answer some of the questions like why are there so many kinds of animals and plants in the world. It seeks to answer why some of these animals and plants are rare while others are common. Some animals and plants are widely dispersed while others are confined to a limited place. The science of biogeography seeks to explain the reason as to why this is so. There are some parts of this world that are richer in terms of species compared to others. Its only by use of the study of biogeography that we can be in a position to understand this. There are several major types of biogeography distributions. They include; Endemic (restricted to specific locations), cosmopolitan (e.g.Caenorhabdities elegans and Drosophila melanogaster), and Disjunct (separated). The disjunct biogeographic distributions are believed to have been caused by Vicariance and dispersal. In biogeography, evidence that can be based on its history can be classified in terms of Paleontology and systematics. 1.) Describe the 5 observations upon which the science of biogeography is founded. Give TWO examples for each observation. a) Each and every species and other higher group animals are said to have a discrete and a non random distribution in time and space. A good example of this is the gorilla that is only found in two African forests. b) In different geographical regions of the world there is an assemblage of animals that are distinct and they coexist. A good example to explain this is the fauna that is found south of the desert of Sahara together with its monkeys, antelopes, pigs and this is totally different from the Australian fauna and its duck billed platypus, wombats and kangaroos. c) The differences and the similarities in these regions cannot be in any way be described in terms of the distance between them or even the area of origin. A good example is that the fauna of eastern Asia and Europe is to large extent similar although they are both separated by 11,500km of land. Also the fauna of New Guinea and Borneo are different though are separated by a small piece of land compared to the ones abov e which is across water and land. d) All those faunas that look different from those of today once previously occurred in all other geographical regions. An example is the dinosaurs which existed in most parts of the geographic locations in Cretaceous. e) The faunas which resemble the ones found today and their antecedents once occurred, but its sometimes at far distances from the current range. A good example is the subtropical-warm temperature fauna which is found in Eocene Wyoming. This includes fishes which are fresh-water, turtle groups and salamander which are restricted to southeastern parts of the United States. 1.) Discuss this statement: â€Å"The history of biogeography is essentially a continuing conflict between creation myth and empirical science.† Empirical science describes that the distribution of organisms in the whole world was as a result of continuous evolution of the past existing species. Science asserts that the present fauna and flora are as a result of evolution from past organisms which were not developed as they are today. On the other side of the creation myth, people and especially the Christians believe that the current population of plants and animals are a product of what God created long time ago. Some of the things that are explained in the bible are in total conflict with what science has provided a detailed account on. A good example is the Global Flood during the time of Noah. The Bible says that God instructed Noah who by then was 600 years old to construct an ark. Noah was then supposed to take two of every unclean animal and seven of every clean animal. All food and fresh water was then supposed to be in the ark. Noah and his family were to remain in the ark for six months until the flood waters subsi ded. This creation story in the book of genesis continues to explain that after the flood waters subsided, Noah, his family and the animals that were released then were the ones who later repopulated the earth. This is in total conflict with the empirical scientists who argue that today there is too much of genetic diversity in the world for us to be consistent that every animal that is land based descended from the few breeding pairs and this is just some few thousands years ago. According to empirical science, some of the species we have today in the planet will evolve locally. This thus means that they are immobile geographically according to scientists. The scientists will ask today how comes the Duckbill platypus ended up only in Australia and not anywhere else in the planet. Scientists still argue that Noah did not take any fish or coral in the ark. During the flood thus, all the fish would have become extinct and all the corals would have been swept away. Some of the corals according to the scientists even appear older than the given history of the floods. For scientists they believe that there is no way the short lived species could have survived the time they were in the ark. They say that the adult mayflies would have died in just a few days while the larvae of many mayflies will require shallow fresh and running water. Other similar insects and many of them would actually face the same problems. There is no way the scientists would believe that the human population could rebound in such a short period. Other controversies apart from the field of evolutionary biology can also be seen in cosmology, thermodynamics, paleontology, geology and nuclear physics. 1.) Describe the main contributions to biogeography of the people listed below. Alexander von Humbolt, Liebig, MacArthur and William. Alexander Von Humbolt: He was German naturalist who is normally referred to as the father of phytogeography. He was the one who felt that study on geographical distribution was an important scientific inquiry that could lead to the discovery of laws of nature that are fundamental. He was the one who did the explorations of South and Central America together with Aime Bonpland who was a French naturalist. These two travelled along the Orinoco and Amazon rivers as they explored the Andes and the present day parts of Ecuador, Venezuela and Colombia. He managed to study vegetation and climatic conditions of Urals Mountains, Siberia and Caspian Sea. He was the one who invented the isobar and isotherm which are used today in description of climatic associations of plant communities. He had a passion for the beauty of nature. He had a good description of the physical environment together with the plant distribution that are widely used in biogeography. Liebig: He was born in Darmstadt, Germany. He went to Paris where was working in the laboratory of Joseph Gay-Lussac. His main interest was in chemistry. He did much in order to establish chemistry as a discipline. He started the first chemical periodical for scholars. He was the one who showed that studies like physiology, agriculture, and psychology are only intelligible if based on sound chemical principles. He was one of the contributors in discovery of isomerism (a condition where two different compounds may have the same chemical formula). He showed that organic compounds can actually be dealt with in a rational way. He once rejected the current humus theory. He showed his contrasting idea by describing that some plants will leave the soil richer in terms of carbon that they really found it. He visited England once and was not happy with the way they were setting out their sewage to the sea. He was of the opinion that they should use their sewage as a fertilizer. William: He collected vertebrates in many remote regions of Hispaniola between the years 1916 and 1923. He also did collections in other regions of the world like the famous Himalayas. To date, most his collections are still in Smithsonian. He is landscape ecologist and a biogeographer. He has made tremendous contributions in the understanding of landscapes and disturbances. His research in these fields has made tremendous influence on the field of biogeography and also the academic biogeographers. MacArthur: He came up with the MacArthur and Wilson equilibrium model on insular biogeography. This is a model that is used to provide a good foundation on the distribution of species on islands. Its also useful in explanation of the composition of insular biotas. Its because of his model that many analyses have been made on the distributions of mammals on insular habitats. 5) Describe the relationships among the following physical factors:pressure, physiography, ocean currents, latitude, temperature, light, precipitation, and wind Physiography is a description of the features and even phenomena of nature. Most of the physical features of the world cannot be well described unless we use other factors like temperature. Physiography stands for physical geography. What is in physical geography is all the physical features like the mountains, forests/vegetations among others. When we attempt to describer any climatic condition of a place or of a certain region, we use temperature, the level of rainfall/precipitation and the effects that winds may have on it. It therefore translates that we cannot describe most of the physical phenomena without using the other factors mentioned. They interdepend on each other for description of physical phenomena. Ocean currents depend on pressure. They usually move from where the pressure is low to where its high. Wind is said to be air in motion. Air can only be in mo0tion if one region has a high pressure compared to another. Air moves from high pressure centers to low pressure centers. This is wind. It therefore means that wind can only be thee if there is difference in pressure amounts in two regions. Ocean currents are usually associated with the precipitation. They usually make the nearby areas in the ocean to receive rainfall if they are usually accompanied by high temperatures. Areas of low latitude have high temperatures while high latitude areas are generally cool. Light intensity in certain ecosystems helps the growth of specific organisms. Physiography/physical geography cannot be fully described if light intensity is not going to be applied to describe some of the conditions in some places (physical phenomena). 1.) Give the Holdridge Bioclimate Classification of climate for the following places: Honolulu, Hawaii; Adelaide, Australia; Timbuktu, Mali; La Paz, Bolivia. Timbuktu (Mali) Class 35; according to Holdridge bioclimatic classification it is in a tropical dry forest. The climate is characterized by high temperatures all year. There is however a better developed dry season compared to the tropical rain forest. The soils are just like for the tropical rain forest. Most of the evergreen tree species become deciduous. Tree canopy is lower compared to tropical rain forest. Undergrowth is dense. There is lower species diversity. Trees have thicker back and small leaves. Roots are long and trees have thorns also. Larger mammals are more dominant Honolulu (Hawaii) Class 25; subtropical desert scrub with an annual climate of 24 degrees. Average temperature in a day is 29 degrees and the minimum is 21 degrees. Its humidity is moderated by its mid-ocean positioning. There is intense rainfall in the winter months though most of the winter days have warm bright sunshine. Rarely will temperatures go beyond 32 degrees. Adelaide (Australia) Class 30; subtropical rain forest Generally, rainfall is more than 1300mm. there are fertile eutrophic rocks. A multi layered canopy of between 10 and 60 species of trees. Most of these trees will exhibit buttressing w2hich is a feature that is common in rain forest areas. La Paz (Bolivia) Class 27; subtropical dry forest 2.) Define endemism. Give and explain five characteristics associated/correlated with areas of endemism. This is a situation where a plant or an animal taxon is said to be restricted in a geographical range or a particular region. Since the times of Darwin, it has been known that islands are the ones which are mostly rich in endemic species. Endemism will arise because of several mechanisms. The major one is the geographical isolation. In this geographic isolation, a small population that has a limited genetic diversity may be isolated. After several generations, the drift in genetics will lead to formation of a distinct species. A population that may arrive on a new island may fill different ecological niches. Other generations of natural selection may result in formation of distinct species. Again, a certain species that was widespread may suffer extinction. This island may now become a â€Å"refugia†. This describes the origin of the major species of Macaronesian endemic â€Å"laurels†. These are mostly found in the Mediterranean region. Latitude: species richness of most organisms in an endemic region increases form high temperature to low tropical latitudes. Lower latitudes have high levels of endemism. Species richness: The levels of species richness and those of endemism cannot be said to be infrequently correlated. Oceanic islands have high levels of endemism but will have low numbers of species. Unusual environmental conditions: Most endemic areas are known to have environmental conditions that are very different from other areas. There occurs independent evolution of the local adaptations. These will mostly enable the species to persist under the existing conditions. Isolation: Almost all areas of endemism are separated or isolated from others geographically. There are barriers to other areas such that even independent evolution is going to give rise to endemic taxa. Historical: In these areas there are usually changing abiotic and biotic environmental conditions. High levels of endemism may be associated with areas that have long-term ecoclimatic stability. This can even enable these populations to be able to survive global changes in climate conditions. 1.) Describe the three possible tectonic plate boundaries, give an example of each and explain the possible consequences of a convergent boundary. Divergent boundary: Its the soft boundary and its also called the spreading center. Two plates move away from each other and mid-ocean ridges will be formed. Magma from the mantle will move though a crack to the ocean and it then cols. This cooling causes the formation of oceanic crust on both sides of the vent. When the plates continue to move, more crust will be formed. The ocean basin then expands forming a ridge system. This crust formed causes the pushing of the plates on either side further. A good example of this kind of plate boundary is that of North America and Europe. Convergent boundary: Its also called a subduction zone. This is a plate margin where one plate will override the other. This forces the other into beneath its mantle. They are boundaries which are in the form of trench. Old oceanic crust will go into these systems as there is new crust formed when the centers are spreading. They are usually locations of strong earthquakes as the action of the plate that is going down interacts with the overriding one. It can also be as a result of volcanic activity. A good place to be associated with it is Japan. The plate that is going down the other will continue to become even hotter. This is because of its proximity to the mantle. The plate will thus melt to form magma. This magma will move upwards through the crust and volcanoes are formed. A good example is the Aleutian Islands. Conservative/transform boundary: Its called conservative as there is neither creation nor destruction of plate materials at the boundaries. What usually happens here is that the plates will slide past each other. These are usually areas where there are many earthquakes. They are caused by the accumulation and release of strain when the plates slide past each other. Good examples of conservative boundaries are the San Andreas Fault in California and mid-ocean ridges, the Rockies in North America. Possible consequences of convergent boundary: These are areas that are earthquake prone. These earthquakes can cause a lot of deaths to human beings and animals. A good example is the 1883 eruption of Krakatau volcano of Indonesia that killed more than 37,000 people. The hot magma contains some chemical that may be harmful to the human beings and also the existing vegetation. Where these big mountains are formed after the plate boundary formation, climatic conditions may change which may not be conducive to the existing flora and fauna.

Osmosis in Potato Tissue

Biology Aim: My objective is to plan and conduct an  experiment from which I should be able to draw a firm conclusion that  will either prove or disprove any predictions I make. This essay aims to assess and investigate the effect of various solution concentrations on the activity of osmosis in plant tissue. Background scientific theory: Plants exchange gases (CO2 and O2) in maintaining vital respiratory processes and in carrying out photosynthesis; they absorb certain minerals and sugars so to use as a source of energy and eradicate wastes in order to maintain specific requirements for survival.Large amounts of water are absorbed by root hairs and are then distributed across the cells of plants by the process of osmosis; water being essential to life, assists cells in executing crucial chemical processes. Molecules travel by two means; active transport or passive transport. Active transport is the movement of a substance from a low to high concentration against the norm concentr ation gradient. Hence, the process requires expenditure of energy, and the support of a carrier protein. Passive transport, however, does not require energy but occurs spontaneously instead.It is a form of transport by which molecules move along a concentration gradient, from an area of higher concentration to an area of lower concentration. Passive transport includes osmosis and facilitates diffusion. Osmosis is a special case of diffusion; it describes the passage of a solvent from a weaker solution, where there is higher water potential, to that of a more concentrated solution that has a lower water potential through a partially permeable membrane in order to achieve the state of equilibrium. A partially permeable membrane acts as a barrier to some substances but allows others to penetrate through freely.Within any plant cell the cytoplasm and cell sap within the vacuoles are of a variety of substances such as salt, sugars and proteins. In theory, water will diffuse into the cell by osmosis if the solution surrounding the cell is weaker but when enclosed by a stronger more concentrated solution than its contents than water is drawn from it by the same process. As a result it becomes flaccid; the turgor pressure falls, the vacuole collapses and the cytoplasm shrink away from the cell wall. This may result in its wilting or death. Plant cells have a cell wall as well as a plasma membrane.The cell wall is a strong and rigid structure that is used by the cell to create osmotic pressure within the cell. This pressure can build because of the rigidity of the cell wall. The cells within a plant that contain high water pressure act as the plant supportive structure, helping to give it its shape. When gaining, the vacuole will expand and press outwards on the cytoplasm and cell wall but since this cannot be over stretched there is a resistance on the inflow of water by the un-stretchable cell wall. This resistance results in turgor pressure exerted by the vacuole on the cell walls.When the vast majority of the cells within the leaves and stem of plant are turgid, its stem will be firm and upright and the leaves straight therefore providing mechanical strength. Similarly a flaccid celled leaf will be limp and the stem will droop; such plants are thought to be wilting. Factors that affect the rate of osmosis (potential variables) The rate of osmosis is much dependent upon a number of factors; the temperature, the nature of the solute, the difference in concentration of solute on either side of the membrane, and any external pressure applied against the direction of flow.Concentration: – The  concentration  of a chemical  solution  refers to the amount of solute  that is dissolved in a  solvent. The concentration of any solution or plan tissue is directly linked to its water potential; the higher the concentration the lower it water potential. Water potential is a measure of the potential of water to enter or leave. Within a di lute solution there is a higher proportion of free water molecules hence water will flow from the dilute to concentrated solution; it is said to have a higher water potential.The maximum water potential is nil; an example of which is within pure water hence water molecules will flow from it to any other aqueous solution regardless of how dilute it may be. There are three possible concentrations of solution. The first, a hypertonic solution, has a higher solute concentration than that of the cell and as a result the water will leave the cell resulting in collapsed vacuoles in plant cells. A hypotonic solution, however, has a lower solute concentration than the solute concentration inside the cell and hence the net movement of water inside the cell is at its maximum.Whilst an isotonic solution is when the concentration of solutes is the same inside the cell as it is outside of the cell; in such as case the cell would not lose nor gain any water. This state is otherwise recognized as d ynamic Equilibrium where the molecules are randomly distributed despite there still being a rapid net movement of water across the cell membrane in both directions; water movement in opposing directions occur at the same rate and thereby ‘cancel’ each other out.Larger differences between the concentrations or water potential of the solutions results in a steeper concentration gradient, meaning a faster rate of osmosis. In effect the concentration outside of any cell is proportional to osmosis rates and therefore the higher the concentration of the solution the higher the net movement of water. Concentration is the factor which is to be assessed in the following experiment; it can be altered by diluting the solution with distilled water whilst keeping the volume constant, (i. e. a 0. 8 molar sucrose solution would consist of 2cm? f distilled water with 8cm? of sucrose solution equivalent to 10cm? of a mixture. ) Temperature: – The rate of Osmosis is also reliant u pon the kinetic energy of the particles being diffused. Since energy is directly related to heat, temperature governs the amount of kinetic energy the particles have. The general temperature of the room in which the experiment takes place will influence measurements of mass of the potato; hence it is important that we ensure that it remains ambient throughout our experiment in order to increase the reliability of our measurements.Ultimately as temperature increases or decreases, the rate of osmosis should also increase or decrease in relative, causing the potato chips to lose/gain mass at a faster/ slower rate. Temperature is therefore directly proportional to the rate of osmosis. Surface area to volume ratio- Additionally the surface area of the plant tissue or in this case the potato will also influence osmosis; the larger the surface area, the more cells are directly exposed to the liquid solution; therefore more water can transfer through the membranes of the cells at any one ti me resulting in a more massive net movement of water by osmosis.Size of Potato;- A large sized potato is likely to contain more  substances. Therefore it is likely to contain more water, which can  affect osmosis as there will be an increasing concentration of water,  which, as the potato's size increases affecting the overall movement  of water depending on the concentration of solution that the potato is  kept in. All potato chips shall be approximately at the same mass initially (1. 6g ± 0. 2g) Plant Tissue:-Where the potato was sourced from will also greatly affect the osmosis rates that are observed by its change in mass also whilst some may be old others may be fresh. In theory osmosis rates will be considerably more efficient in newer than older potato strips for the reason that in older ones its cells may be more damaged or be on the verge of decay. Hence the permeability of the potato can too be determined by its age; its age and permeability to the larger exten t are in inverse proportion therefore.Type of solution:- Different solution types ( i. e. sucrose, glucose, potassium chloride and sodium chloride) will differ from one another in that the size of the molecules of the solute may be larger in one that the other. this will affect osmosis rates within the plant tissue in that smaller molecules will be able to penetrate through the partially permeable membrane with far more ease than larger ones ; hence the smaller the molecules of the solute the faster the rate of osmosis. Time; –The time given in which the plant tissue was immersed within the solution would also affect the experiment, as we would expect that with a longer duration, there would be more time for osmosis to occur. Pressure; – The pressure on one side of the membrane can increase or decrease the rate of osmosis by pushing the solution against the membrane. Selecting a factor â€Å"An independent variable is that which is presumed to affect or determine a de pendent variable[1]†. It can be changed as required, and its values do not represent a problem requiring explanation in an analysis, but are taken simply as given.More generally, the independent variable is what someone actively changes; while the dependent variable is what changes as a result. The constant variable or otherwise known as controlled variable, however, is never changed during an experiment as it remains ‘constant’. During my experiment I shall be measuring the change in mass of the potato chips as the dependant variable in order to investigate the effect of different concentration of sucrose solution (independent variable) on osmosis.Other factors such as the room temperature, type and volume of solution, form and size of plant tissue shall remain ambient through out my investigation as controlled variables or otherwise ‘constants’. Qualitative, Quantitative and Testable Hypothesis Osmosis is defined as being the net movement of water f rom a region of high concentration to that of a low concentration. This  movement must take place across a partially permeable membrane such as  a cell wall, which allows only explicit molecules to penetrate through but obstructs the pathway of others.Diffusion will continue until the area in which the molecules are found  reaches a state of equilibrium where molecules are  randomly distributed throughout solution. By my scientific background knowledge I can make a number of predications; I hypothesize that the rate of osmosis will differ in all test tubes depending on the concentration of solution, resulting in some either gaining mass in becoming turgid, others remaining the same whilst the rest lose mass and being flaccid after being immersed in solution subsequent to a fixed period of time.I hypothesize that plant tissue immersed in solution of higher concentration than that within the cell itself (hypertonic solution) will loose mass because there will be a net movement of water through the partially permeable membrane outside the cell where there is a considerably lower water potential. The plant cell becomes flaccid and as a result of the ell membrane shrinking and pulling away from its cells walls, it said to have been plasmolysed. Likewise, I predict that if the plant cell is placed in a hypotonic solution where the concentration of solution is lower than that of the cell than water is absorbed by osmosis.The plant cell swells and shall become turgid to the extent that the pressure within the cell matches the internal or turgor pressure. The turgor pressure shall prevent further uptake of Water preventing it from rupturing. More generally the concentration of the sucrose solution in the flasks is inversely proportional with the plant tissues change in mass; as you increase the concentration of the solution, both the mass and the length of the potato chip will decrease.This I shall prove by measuring the mass of the plant tissue before it being and subsequent to being submerged in solution. Data collected shall be handled and substituted into the following equation . . . . Final mass (g) – initial mass (g) X 100 = Percentage Change Initial mass (g) A negative percentage change will signify that water has been lost by its net movement through the partially permeable membrane whilst a positive one will suggest that there has been a gain. I predict that my findings when transferred onto a graph will have a similar trend as in the one shown below.Preliminary The main objective of carrying out four preliminary experiments was to inform me as to which instruments would be most efficient in its use, gain first hand practice and recognize suitable methods in order to conclude specified measures which I will be using in ensuring that my final investigation is of highest standards in its reliability. |Concentration (Mole)|Mass(g) |Percentage change of | | | |mass (% to 1 d. ) | | |Before |After |Change | | |1. 000 |2. 32 |1. 97 |0. 35 |15. 0 | |0. 500 |2. 30 |2. 24 |0. 06 |2. 60 | |0. 250 |2. 28 |2. 23 |0. 05 |2. 20 | |0. 125 |2. 32 |2. 59 |-0. 27 |-11. 60 | Preliminary experiment 1 – Equipment: ? cork bores (5mm) potato ? glucose solution ? ruler ? tissue ? distilled water ? scalpel ? pipette ? test tubes x4 ? measuring cylinder ? scales Key: outlier Experiment 1 varied the concentration of the glucose solution; from the readings observed a clear correlation can be identified as a result of measurements being wide ranging- as the concentration of the glucose solution reduced by half each time the mass of the potatoes reduced too and hence there is a proportional correlation between the independent and dependant variable.Such readings are scientifically explanatory and correspond with my initial prediction produced in the previously discussed section of the hypothesis. One major setback of this investigation was that I used too few solutions with varying concentrations and hence the readings ava ilable in giving evidence of any judgments on my findings or when proving/disproving my initial predictions are limited.Hence, if I were to further develop this investigation as my final one I intend on using 5 different concentrated solutions that range from 0. 2 to 1 molar with increments of 0. 2moles. In this investigation we failed to use distilled water but instead opted for tap water because we had forgotten; this is much likely to have reduced the reliability of my results because any dissolved substances within the water will have affected the rate of osmosis by changing the solutions proposed concentration.In the final experiment we shall therefore use distilled water. However, I believe that my readings from the first preliminary experiment are reasonably fair and reliable because no outliers which contradict the key identified trend can be found and the mass of the potatoes previous to and subsequent to the experiment was accurate to 0. 01 of a decimal place. The potato w ith which we worked with was . . . . . . Preliminary Experiment 2 Equipment: cork bores (5mm) ?

The measurements that were collected were few; by 45, 0 and 25 degrees acting thereby as a disadvantage because we are restricted in the amount of data available in proving the trend. It is suggested that the higher the temperature the higher the osmosis rates; our observations are fully explainable, expected and scientifically conventional.It is known that temperature has a direct relationship to the movement of particles across a membrane; therefore as temperature increases, the rate at which particles move across the membrane should increase too as its molecules will be more excited in having more kinetic energy. Nonetheless if the temperature were to rise too high the selective permeability of the membrane can be damaged due to becoming denatured hence permanently collapsing the process of osmosis; this could be investigated by experimenting with temperature at or over 60 degrees.If I were to further develop this investigation with temperature being the independent variable I would take 4 measurements with increments of 20 degrees with minimum values of -20 to 60 degrees. My results here are less accurate by my use of only an average the rmometer as it is corrected to the nearest centigrade measured; consequently if I were to develop this experiment I would prefer to use a data logger which will give me values that have been rounded to the nearest decimal place with a considerably smaller error tolerance.In all of our preliminary investigation there was a reaction time of 30 minutes given; this however in my opinion is unreasonably low because the process of osmosis may have not yet reached its maximum capacity or equilibrium; hence in the final experiment there will be 45 minutes given for each set of vegetable cylinders. We did not use a stop watch or any other means of measuring and setting the reaction time other than the classroom clock and our best estimates; this may have hindered the reliability of our measurements so I shall use an stop watch in the final experiment which is accurate to

Course outline

Aims This course will provide students with an understanding of six ancient civilizations through archaeological and documentary sources. These SIX ancient civilizations are Mesopotamia, Egypt, the Indus Valley, northern China, Mesospheric, and the Andes. The course has three related goals: (1 ) to trace the historical formation and collapse of these six societies; (2) to examine explanations that attempt to account for their trajectories; and (3) to explore the methods researchers use to study these topics.Outcomes By the end of the course it is expected that the student will be able to: locate six major ancient civilizations and their cities on maps; understand and critically analyze the range in current theoretical approaches to the development of violations; recognize and critically evaluate the methods employed to access the past organize material and to articulate arguments effectively Grading Quizzes The quizzes will consist of multiple-choice questions and map identifications .Quiz 1: Quiz 2: Quiz 3: Examinations examination: 30% Final examination: 30% Extra Credit Students may add 5 points to their midterm or final through extra credit work at museums or lectures relevant to this class. Among the suggested exhibits are the permanent Egyptian displays at the Metropolitan Museum of Art and the Brooklyn Museum, and the Micronesian and South American exhibits at the American Museum of Natural History, but many other exhibits may also be appropriate. Students must write one page assessing the exhibit or lecture and provide proof of visit.Knowing them well will allow you to proceed to graduation efficiently and with a strong transcript. Study carefully everything in Brush's statement about academic honesty. You can access it easily from the Burch College home page, where the link â€Å"For Current Students† leads to a page where you can find a link to â€Å"Academic Honesty Policy' under â€Å"Resources and information†. Also feel free to ask a ny instructor for clarification or for explanation of why professors take this issue so seriously. This course has a ‘zero tolerance' policy on cheating and improper behavior during quizzes and exams.Any student who breaks academic rules in this course has violated the mutual trust on which teaching and learning are based and will receive not only a zero on that assignment, but a grade of F for the course. For serious infractions the instructor will ask the College's Disciplinary Panel to suspend the violator from all Burch courses. By College policy, all suspected violations, whether infirmed or not, are reported to the Dean of Students. Disruption of class is not permitted. Rude behavior is disruptive. Arriving late/leaving early is also not acceptable and repeated latecomers/early leavers will be penalized. Pods and cell phones off before class. Please do not eat food within the classroom. It is distracting to other students and to yourself (you should focus on the lecture! ). Content Overview The areas that we will study are Mesopotamia, Egypt, the Indus Valley, northern China, Mesospheric, and the Andes, that is, the birthplaces of the pristine states that armed the core of early civilizations. Their societies occupy a special place in human history, because they produced the first social classes, economic specialization, state government, and urban settlements.Their populations created the earliest formal philosophies, religions, monumental architecture, legal codes, market economies, institutionalized militaries, and writing systems. Their members began to define separate spheres of secular and religious activities and public and private life. In short, if we want to understand how human societies were transformed from small roofs to diversified empires organized on a grand scale, these are the regions that we study.

Vegetarianism and Environment Essay Sample

Vegetarianism and Environment Essay Sample Vegetarianism and Environment Essay Example Vegetarianism and Environment Essay Example A vegetarian can be described as someone who does not eat meat, fish or any other animal products in most cases, because of religious, moral or health reasons. Over time, vegetarians have been looked down upon in the society with few ready willing to take the path to being a vegetarian. However, this has changed with time with people getting to know the benefits that come with being a vegetarian. This has led to a high number of people being vegetarians. Although scientists have not yet established clear explanations of how animal products, especially red meat, lead to some health complications among people, the relation between the two cannot be underestimated. Current paper seeks to discuss the benefits that come with one being a vegetarian and look at why people should strive to adopt this kind of lifestyle for the benefit of their health. The paper further proposes healthy tips that people should adopt as an alternative to animal products. Benefits of Vegetarianism One aspect of biomedical research that needs to be first acknowledged is the role the field has played in changing people’s attitude towards vegetarianism. Medical research on the benefits of vegetarianism has led to people realizing that indeed vegetarianism can play a key role in preventing some chronic diseases such as gout (Greeley, 2009). The common belief that a scientific research carried on the effects of red meat gets carried by a small proportion of scientists holds no water. Despite the relatively small ratio of these researches, their outcomes all point to a common conclusion, which is the need for people to adopt vegetarianism. Red meat can be described as one of the most controversial goods in the history of human nutrition. Despite the fact that human beings have been taking it over the cause of time, many people believe that it can indeed cause harm to human beings. Scientific research has discovered a trend in that people who take less red meat in their diet are less likely to develop lifestyle diseases such as gout (Greeley, 2009). Despite there not being a conclusive explanation to the above observation trend, the observation calls people to adapt to this trend. After all, people stand to lose nothing by taking less of meat in their diets. As earlier pointed, people choose to become vegetarians for several factors. Among these factors are the apprehension for exceptional wellbeing and the surroundings as well as financial and humankind starvation concerns. Other people may choose to adopt vegetarianism, because of a personal love for animals as well as a belief in being non-violent to these animals (Hobbs Jacobson, 2010). However, the outstanding factor that should lead people to being vegetarians is the advantages attributed with the lifestyle. It is equally worth noting that people may be converted into being vegetarians for one factor, but later on identifies some other factors, as well. Vegetarian nutrition is more prevalent among young people with eating complications than in the broad population. Conventionally, study of vegetarianism pointed mainly on latent dietary deficiencies, but in recent years, the pendulum has gone the other approach, and studies are confirming the health advantages of eating diets free from meat (Towns Towns, 2001). Nowadays, food derived from plants gets recognized as not only nutritionally satisfactory, but also as an approach to minimize the risk for most chronic diseases. In July 2009, the American Dietetic Association came up with a position paper, concluding that properly premeditated vegan diets, together with total vegetarian or vegan diets, are nourishing, nutritionally satisfactory, and may supply health reimbursement in the deterrence and handling of certain diseases (Hobbs Jacobson, 2010). Human beings tend to regard with high esteem animal products. Indeed, in some contexts, taking too much of these products gets regarded as being ‘classy’. This should not, however, be the case. Human beings should apprehend that it is their role to protect their health from any nutrition that may put it at risk (Horsman Flowers, 2007). However, this should not be taken to mean that human beings seize to take these products completely. Some of the animal products, especially white meat from fish and poultry meat, have a wide range of benefits to human beings. Livestock rearing, according to most vegetarians, has a negative effect on this planet. A vegan suppose that producing foodstuff through mammal farming is unproductive because animal feed production takes up a lot of terrain, manure, water, and other capital. This capital could be rechanneled to providing food for human beings. In the quest for higher yields, most vegans suppose that livestock rearing is accelerating topsoil erosion; reducing its output for the crop growing of crops. A great deal of wasteland gets rehabilitated to grazing and farm land because of this (Horsman Flowers, 2007). A significant amount of contamination in groundwater and rivers comes from animal desecrate from enormous feedlots and plant farms. This further leads to more harm than good to humankind. Eating animal fats and proteins can be indicated in several researches to increase a persons risk of developing a number of diseases such as cancer, diabetes, heart diseases, as well as rheumatoid arthritis. The fat composition of cow’s milk cannot be compared to human milk. According to most vegetarians, human beings should not be destined to take cow’s milk, but rather their own milk. Men with early signs of prostate cancer should take fast initiatives to change their diet. This can help terminate or in some case reverse the advancement of their illness (Melina Davis, 2003). While this may not adequately reverse their health conditions, it can be of high importance in helping such people lead a healthier life and increase the prospect of them living with the disease for a longer time. Another U.S. research involving 500,000 people identified that people who took red meat as well as other processed animal products died more prematurely than other people. A document taken from Food Technology in October 2012 discusses that plant-based diets either reduce or completely do away with peoples genetic tendency to mounting chronic diseases, such as diabetes type 2, cardiovascular disease, and cancer (Towns Towns, 2001). Whole grains, vegetables, fruits, and legumes hold no cholesterol and are low in fat, particularly inundated fats. Equally, these products provide a lot of fibers and other nutrients. Vegans propose that people should take plant based foods that contain high levels of proteins instead of taking animal products. In the United States, an estimated 26 million animals get slaughtered every year to cater for the demand for animal products. Out of this number, 65% provide red meat to the market. Using the above data, it can be observed that most of these animals pose a threat of promoting the above discussed diseases. While these figures may seem to boost the agricultural sector in the United States, the impact it has on the health of American citizens cannot be underestimated (Towns Towns, 2001). This can be attributed as one of the reasons for the increasing number of lifestyle related diseases among people even in their youth. The trend is unlike what got experienced over the past where such diseases got only associated with the elderly. Another study in the United States indicated that six to eight million grownups do not take meat of other related animal products. According to data released by Vegetarian Resource Group, millions of people are elimination red meat from their diet each year in the US. This trend has been a result of a worldwide campaign by healthcare professionals on the need for people to take less and less of these products. One factor that scientists believe leads to the health risks associated with taking meat is that most of the animals from where these products get obtained get chemically raised with an aim to increasing the rate of their growth. Chemicals get used in these animals. These chemicals, which most remain in the animals’ bodies, in some other forms, get transmitted to human beings when they take these products. As Marc Bekoff, a professor at the University of Colorado puts it, â€Å"some people say without hesitation that they love animal products and then deliberately lack to look at the effects of these products on their health. I am just glad that I do not love these products†. Marc’s statement illustrates the hypocrisy with which human beings treat animal products. While most people will claim that they love animal products, few are willing to look at the effect of these animal products on their health. This love cannot be taken to have good intentions on their health. One argument that can be put forward to address this issue is the prospect of using the already available knowledge in science to develop less hazardous animal products. Science has come of age, and scientific breakthroughs got made over this time. Why not use this knowledge to work on new breakthroughs instead of subjecting people t a life without animal products? Would not this approach provide equal, if not better, results than boycotting taking animal products completely? Scientists need to work on the viability of the idea posed by these two questions. Scientific research on animal products has at times indicated that these products can lead to spread of diseases from animals to human beings. In some cases, tests done on animal products fail to indicate infections in these animals at their early stages. In a research carried out by scientists, it got established that continued use of a drug on an animal can lead to the animal developing a resistance to the disease (Nodine, 2009). When people take meat from such an animal, the disease is likely to be passed in a new model to human beings. Many scientists can associate diabetes II with the above finding. Animal studies on the benefits of taking meat in one’s diet in most cases can be flawed by design. A group of scholars from the Vanderbilt University Medical Center described these studies as having many problems related to the design and logistics followed. â€Å"The design of studies on animal products involuntarily reins many variables that can mystify human health† (Tessmer, 2010). These researchers argued that human health disorders resemble those of animals but are rarely identical. However, as long as these disorders are not identical, the level of success of these studies will never be guaranteed. The main challenge that health professionals face when trying to explain why red meat is dangerous to human health is the traditional notion, which people get always encouraged to take more of proteins in order to retain their healthy status (Duyff ADA, 2006). People, however, need to realize that this has changed with time and what was once an advisable idea has turn to be hazardous for human health. This calls for people to change their perceptive towards animal products as the only way to meet protein needs in their bodies. They should seek to adopt plant based food that supply humans with proteins. This happens because animal products, especially, red meat poses a great threat to human health in regard to lifestyle diseases. One way that health professionals propose that can help reduce the effect of red meat on people’s health is ensuring that this meat gets adequately cooked. Red meat has been known to transmit worms to human beings when not properly cooked. This is because this meat requires to be cooked at high steam levels for these worms to die. However, most people do not seem to prefer this approach since it makes the meat less ‘tasty’ (Duyff ADA, 2006). As most health professionals would suggest, one cannot eat their cake and still expect to remain with it. In order to address lifestyle disease associated with red meat, people have to be bold enough to appreciate that red meat does not always have health benefits. Consumption of animal products has raised debate over their impact on human health. Health professionals can be seen to recommend that people take less and less of these products while adopting more grains to their diets. Although there has been little proven explanation that has identified the cause of lifestyle diseases to consumption of animal products especially red meat, research has established a relation between the two. Most lifestyle diseases have been established to be related with consumption of these products. In order to reverse this trend, people should consider adopting vegetarianism. Although some critics argue that there are not clear established benefits of being a vegetarian, the lifestyle can indeed help one avoid some of the health disorders associated with animal products. This may prove a great step towards addressing the issue of lifestyle disorders among people. Vegetarianism and the Environment Dietary intake in the world is rapidly changing and most people prefer being vegetarian rather than non-vegetarian. The topic has become increasingly influential within the recent decade, largely due to corresponding scientific research in developed countries. Many scientists, bloggers and scholars have frequently argued on this matter. Some believe that vegetarianism is the best way to save the environment. Those who support vegetarianism argue that the production of animal products causes severe pollution and land degradation. On the other hand, scholars who do not support vegetarianism argue that the production of crops requires the use of chemicals such insecticides, herbicides and fertilizers that cause environmental pollution. Current paper provides an annotated bibliography analysis of eight different sources stating whether being a vegetarian helps the environment in any way. The paper analyzes the sources by providing a summary, assessment on whether the source is useful on this topic and a reflection. Human demand for a healthy diet is the main reason of becoming a vegetarian; vegetarian’s diet impacts the environment positively when compared to meat-based diet. Marlow, Harold J., William K. Hayes, Samuel Soret, Ronals R. Carter, Ernest R. Schwab, and Joan Sabate, Diet and the Environment: Does What You Eat Matter? The American Journal of Clinical Nutrition 89.5 (2009): 1699S-1703S. The journal provides an analysis of whether being a vegetarian or non-vegetarian affects the environment. The objective of the study was to compare the environmental impacts of non-vegetarian and vegetarian diets in California. The study was performed by analyzing the level of toxicity produced in the process of manufacturing of both plants and animal products. The outcomes of the study demonstrate that the amount of inputs required in producing non-vegetarian foods were higher that inputs used in producing vegetarian foods. In a deeper analysis, non-vegetarian foods require three times more water than vegetarian foods, thirteen times more manure, two and a half times more energy and one and a half times more pesticides. Marlo et al. (1699) analyze the effects of modern technologies in food production and how it affects the environment. Advancement in mechanization, crop pests control and irrigation has increased the level of environmental pollution. The study indicated that animal p roduction waste in the United States is one hundred and thirty times greater than that of people. If such waste is not treated properly it releases high concentrations of potassium, phosphorous and nitrogen compounds into the environment. The journal is quite useful in this topic as it offers a detailed analysis of both the impacts of being vegetarian and non-vegetarian on the environment. The journal has used reliable sources that include California state agricultural statistics and product production data. The journal obtained its results from both secondary and primary sources. Primary sources provide firsthand information and, therefore, the source is not biased but objective on the topic. This source is 90% more reliable than the other sources in the bibliography. The source has proved that both vegetarian and non-vegetarian foods have negative impacts on the environment. In comparison, livestock production causes a higher level of toxins emission than crop production. Therefore, being a vegetarian is friendlier to the environment than meat diets. Pimentel, David, and Marcia Pimentel. Sustainability of Meat-Based and Plant-Based Diets and the Environment. The American Journal of Clinical Nutrition 78.3 (2003): 660S-663S. Pimentel and Marcia (660) analyze sustainability of crop-based diet and neat-based diet in the United States of America. Four billion people primarily rely on crop products, while only two billion people predominantly rely on meat-based diet. The American food production system relies heavily on fossils. The country uses about 17% of fossils in food production. The level of fossil energy is high and thus, it has proved that production of food in the U.S. is not sustainable. The report analyzes the proportion of land and other resources used in the production of plant-based and meat-based diets. Just in Marlo et al., Pimentel and Marcia (668) state that meat-based diets require more inputs to produce and results in more wastes as compared to human and plant-based diets. Nine million livestock are consumed annually in the U.S. (Pimentel and Marcia, 661). Such quantity of livestock is not enough to feed the American, since it exceeds the human population by approximately five times. The report is useful in current study due to its analyses of sustainability of both vegetarian and non-vegetarian food production. The analysis forms a basis to the study by providing reliable data on energy usage and the level of energy consumption by the two types of diets. The main fossil energy required for crop production includes: pesticides fuel, machinery and irrigation. Input requirements are different depending on the type of crop. The amount of fossil energy required to produce animal products proved to be higher than fossil energy used to produce crops. The data in this report is reliable, since the research used food product with the same calories for both plant-based and meat-based diets. By reflecting on present report, I discovered that in the U.S.A., the biggest number of people consume plant-based diet. Both plant-based and meat-based diet in the U.S. is not sustainable. Even with a fewer number of people consuming meat than those who consume plants the meat-diet cannot sustain the required meat demand. Meat-diet requires more fossil energy to produce as compared to plant-diet. Fossil energy is not renewable and thus, its exhaustion poses a great danger to the environment and to the economic development in general. The resource is helpful to this study as it provides a guideline that creates awareness on sustainability of vegetarian type of diet and the environment, as well. Leitzmann, Claus. Nutrition Ecology: The Contribution of Vegetarian Diets. The American Journal of Clinical Nutrition 78.3 (2003): 657S-659S. Leitzmann argues that the human demand for certain diets determines the welfare of the environment. In return, the environment affects the quality of food produced. Nutrition ecology is the whole process of food chain production that includes harvesting, storage, processing, transportation, trade, packaging, supply and disposal of the waste products. The rise of industrialization and mass production of crop and animal products has resulted in environmental pollution. Studies show that vegetarian diets are suitable in safe-guarding the environment by decreasing the amount of pollution released and stabilizing global climatic changes. Maintenance of the health benefits of vegetarian is paramount and due to its positive relationship with the environment, its status will also improve. Sustainable production of vegetarian diets can be achieved by adopting organic farming and producing food regionally rather than relying on imports. The new type of production ensures that food produced is economically achievable, sufficiently practiced, socially accepted and relatively sustainable (658). Leitzmann analyzes effects of vegetarians diet on the environment by using the dimension of nutrition ecology. His point of view is that the human demand for food affects what the environment will produce. If people demand more meat than food crops then more meat will be produced and less food crop. Nutrition ecology has various disciplines that are interrelated. A number of studies stresses that people should increase consumption of plant-diet and reduce the amount of meat-diet consumed. The content of the journal is useful in present research, since it gives an explanation of how the food chain process starting from production to consumption affects the environment. The study is reliable in researching the topic, since it provides well-guided information on various aspects of the nutrition ecology and how they influence the environment. The journal is not biased in its results; it represents the effects of the whole nutrition ecology on the environment. I agree with the author that the best way to reduce waste produce is to consume food from the farm, while it is fresh and avoid processed food. Industrial processes of both plant-based and meat-based food manufacturing contribute to water, air and soil pollution. However, as compared to other sources in the bibliography, current source is not clear enough on how organic farming and use of unprocessed food can be sustainable. Fox, Nick, and Katie Ward. Health, Ethics and Environment: A Qualitative Study of Vegetarian Motivations. Appetite 50.2 (2008): 422-429. The researchers carried out the study with the aim to determine the motivation behind vegetarianism. To do this, the researcher interviewed 33 participants through an online discussion. The study looked at three main motivations: environment, health and ethics. The research was conducted in U.S., UK and Canada. The results showed that ethical treatment of animals and good health are the main motivators of being a vegetarian. A range of participants also reported that the interest of keeping the environment safe was their main motivation. Researches on motivation behind being a vegetarian have found a range of religious reasons of not eating meat. For instance, the seventh day and Buddhism religion believe more in being vegetarian. Some of the vegetarians avoid meat to stay in good health and lose weight. On the other hand, ethical vegetarians avoid meat since they consider it as unethical and immoral to kill animals for a meal. However, data collected showed that a vegetarian chose t o avoid meat for health concerns (425). The goal of this article coincides with the requirements of the research paper by providing reliable information on motivation to become a vegetarian. The article has based its argument on the results obtained from the primary source that is: obtaining first-hand information by conducting a survey on vegetarians from three different countries. Initial motivation of adopting a vegetarian lifestyle is to achieve the desired health status. The article provides clear evidence that there are various aspects that drive vegetarians choice of avoiding meat. There are also other reasons such as ethical issues, religion and environmental concerns. The study shapes the argument of the paper by providing various aspects that lead people to choosing a curtain type of diet and outlining its overall effects on the environment. Tuffrey Laurie. â€Å"Can Becoming a Vegetarian Help Save the Planet?† Ecologist. 2012. Despite the increased concern about environmental impact of meat-based diet, meat consumption has increased by around 20% (Tuffrey 13). Information obtained from the United Nations Food and Agriculture Organization shows that meat production requires a lot of energy and inputs as compared to production of plant-based diets. Animal welfare is the primary motivator of choosing to be a vegetarian. According to Tuffrey (14), environmental concern ranks second among other reasons that make people choose meat-free meals. The magazine states that most people choose to become vegetarians due to an ethical issue. The study suggests five ways that can help save the environment. People should focus on eating more pulses, lower meat consumption, choose fish, since it considered to be more sustainable than any other source of meat. People should choose to buy food from farms rather than from the supermarket so that to have access to fresh fruits and vegetables. People should also choose seasonal food and consume it when it is in plenty. Present article proves to be very useful for the research, since it provides an explanation on how to sustain the environment. Environment can be maintained by choosing to consume more plant-based diet and reduce meat consumption. The goal of the paper is to make the audience aware of the fact that both plant and meat diets are essential for good health. Therefore, we should use method of keeping the environment safe by reducing meat consumption. Excessive meat consumption leads to land pollution and excessive usage of fossil energy. By reflecting on this article, I discovered that consumption of meat products has increased despite the ongoing campaigns on reducing meat consumption. Meat production and the decision to rely on meat products for food are not sustainable and lead to environmental pollution. Iacobbo, Karen, and Michael Iacobbo. Vegetarians and Vegans in America Today. Greenwood Publishing Group, 2006. Meat production contributes to pollution of the environment through waste products released in the water, manure and fertilizer. Meat production also contributes to air pollution through ammonia produced, hydrogen, dust and manure odor. It is also a major contributor of top soil erosion and disruptor of ecology. Iacobbo and Michael state that any food obtained from animals distresses the environment even if that animal is a bee (94). The book provides a clear indication on how being vegetarian helps the environment, as well as outlines negative impacts of animal production on the environment. Just like in the other sources (Fox and Katie, and Leitzmann), the source is not biased, but it looks at both the advantages and disadvantages of choosing a vegetarian diet and thus, it is found to be suitable in current study. The book provides an analysis of both plant-based and meat-based diet. Not all vegetarians associate environment problems with meat production. Animal right is another aspect that has contributed to the choice of becoming a vegetarian. Metz, Martina, and Ingrid Hoffmann. Effects of Vegetarian Nutrition–A Nutrition Ecological Perspective. Nutrients 2.5 (2010): 496-504. Nutrition is a multidimensional aspect affected by interrelated disciplines. Metz (496) has provided an analysis of how shift in diet has contributed to global environmental changes. Changes in living styles and evolution in industrial production cause pollution leading to environmental problems. Therefore, meat-based diet is not solely responsible for such problems. The four disciplines of the ecological nutrition are the society, the environment, health and the economy. To be in good health, one requires eating fresh food. The health of citizens heavily determines sustainability of economic growth. Both the environment and the society are responsible for each other. A poor environment cannot produce quality food to the society; likewise, if the society does not take care of the environment then it cannot provide the society with goods of expected quality (498). Baroni, Luciana, L. Cenci, Massimo Tettamanti, and Marina Berati. Evaluating the Environmental Impact of Various Dietary Patterns Combined with Different Food Production systems. European Journal of Clinical Nutrition 61.2 (2007): 279-286. Italian scientists Baroni et al. (2007) dedicated their article to practical research on how various types of diet (omnivore, vegetarian and vegan) affect the environment. Aside from these obvious criteria, the scholars have also introduced the notions of conventional agriculture as opposed to organic farming. The essence of the research lies in a three-week-long examination process over the pre-designed dietary samples. In my opinion, the paper has its obvious advantages to present research as it uses a good and solid methodology base, a well-designed research scenario and usage of effective software called Sima Pro-5 (p.280). The technique of evaluating how the dietary choices influence the environment is called Life Cycle Assessment (LCA). European farms are capable of growing enough fruit and vegetables for the whole EU citizens (including the unregistered immigrants), but cannot provide the land area for breeding cattle and other domestic animals. In order to do both, the farmers must use chemicals and synthesized fodder for their animals. It proves that a meat-eating diet is automatically and inevitably becomes a non-organic eating pattern that includes all types of chemical ingredients unidentifiable for a common consumer Baroni et al. (280). Current research has proved that production of meat-based diet is not sustainable and it requires a lot of non-renewable resources. Production of meat requires a lot of fossil energy, while plant-based diet requires only a little of it. Vegetarian diet is sustainable and friendlier to the environment as compared to meat-based diet. Analysis of the above sources proves that the meat industry influences ecosystem very much and it would be a real step forward to increase awareness on the importance of adopting a vegetarian diet.
