Their benefits aside, human diets are polluting the environment and sending animals to extinction. Introduction The fact that the environment and the entire ecosystem have been left unstable in the recent times is in no doubt. However what has continued to evoke many debates is whether humans have had a hand in this unfortunate situation, and if so, by what extent. Though many feel that humans have had a thing to do in this and could do much better in sustaining the environment, some feel that this is a natural occurrence and nature should be left to take its course.Advertising We will write a custom essay sample on Their benefits aside, human diets are polluting the environment and sending animals to extinction. specifically for you for only $16.05 $11/page Learn More This paper explores how man has affected the ecosystem, and specifically so through his diet, and what could be done to put the situation back on track. It is essential that human beings balance their diet. A normal human being is required to take 1,200 calories through the three major meal s he/she has in a day .However, in trying to achieve this environment has been left compromised through the following ways. Excessive harvest of animals in search of various meats is leading to their extinction. Animals are the chief source of proteins and fats which human beings are in need of. Fats are very important in body heat regulation. On the other hand, proteins make the body tissues and up to 15-20% of the calories taken should be made up of proteins. Although this is the case, the animal community is being pushed to the extreme in trying to feed the ever growing population. This has been done through directly hunting down animals and robbing them of their habitats as people clear forests and bushes to create farms. Researchers have shown that some animal and fish species risk being swept off the face of the earth if strict measures are not put into place. This is largely due to their nutritional value. Tuna and sharks are some of the fish species that are facing extinctio n due to the nutritional richness their soup contain. However, human exploitation has been so extensive that some species may never be recovered fully and if it does, could take ages. Allendorf and Hard (2012) observe that: Evolution brought about by human harvest might greatly increase the time required for over-harvested populations to recover once harvest is curtailed because harvesting often creates selection differentials, whereas curtailing harvest will often result in less intense selection in the opposing direction. (p. 1) The need for preventive measures being preferred to reinstating measures is therefore important. Looking for alternative protein sources like legumes and exercising controlled and selective animal and fish harvesting should be embraced. Should we fail to do this, we may wake up one day to find nothing to harvest at all.Advertising Looking for essay on environmental studies? Let's see if we can help you!

In order to meet food requirements for humans, different mechanisms have been put in place to increase productivity. Among these mechanisms, use of intensive fertilizers has been majored. This is particularly so because the more the population, the more mouths that require feeding. This is made worse by the fact that cultivation land continues to be limited. On top of the production advantages, Food and Agricultural Organization of The United Nations (1972) has observed that: The intensive use of fertilizer can benefit the environment indirectly in that, by increasing considerably the yields of foodstuffs per hectare, it allows withdrawing from cultivation land of low quality, such as steep land, land with shallow soils and land very susceptible to erosion. (p. 2) However these fertilizers have been employed in excess leading to en vironmental degradation .For starters, excess nitrates in the soil from fertilizers have been carried into rivers and lakes killing lots of organisms in water .Use of pesticides in farms has also interfered with pollination and caused a lot of poisoning in the air killing lots of birds and insects in the air. â€Å"A number of medical specialists have also expressed concern about the undesirable effects of high nitrate intake on human flesh† (Food and Agriculture Organization of United Nations, 1972, p. 7) .It is therefore justifiable to say that although fertilizers and pesticides have been in handy in helping to boost human diet, they have also been poisonous and endangered the lives of many animals, fish, birds and even humans themselves. Food waste also plays a major part in polluting the environment. Most developed countries especially in the west are facing problems dealing with waste that result from food or the entire food that is not eaten but dumped in landfills. â €Å"Once this food gets to the landfill, it then generates methane, a greenhouse gas 23 times as potent as carbon dioxide in trapping heat within our atmosphere† (Schiller, Cambridge M.A, 2010, p.1).Therefore this means that as humans try to satisfy themselves diet wise, they are polluting the environment in the process by not exhausting what they have in their plates.Advertising We will write a custom essay sample on Their benefits aside, human diets are polluting the environment and sending animals to extinction. specifically for you for only $16.05 $11/page Learn More Venkat (2012) notes that â€Å"the climate change impact of food as quantified by life-cycle GHG emissions is a more complete measure of environmental impact than embedded energy or barrels of oil.†(p.432).It should also be noted that most food thrown out as garbage has already been cooked and the cooking oil used is filtered into the soil rendering it infertile and unproduct ive. On top of these, emissions evoked by vehicles during the transportation of food waste to landfills also pollute the air. Proper measures should be put into place therefore to reduce the amount of food thrown as garbage. People should therefore make use of freezers to keep food fresher for longer instead of dumping it. People should also be encouraged to only shop food quantities that can be easily exhausted instead of buying large quantities only to end them as garbage. If this is not done, the environment will continue being held at the mercy of food waste. In conclusion, human diets are one of the main reasons behind environmental degradation. This is because of the processes involved in achieving them as well as the result of their achievement as noted above by the implications of food wastage. The key lies therefore in efforts to try to sustain population as its rise has had a lot of negative consequences as mechanisms continue to be drawn to make sure humans are fed with t he perfect diet worldwide.

Critique Essay Example | Topics and Well Written Essays - 500 words - 13

Critique - Essay Example I failed to decipher any weakness in the abstract. The author failed to stipulate where the introduction begins. The transition from abstract to the introduction part does not have a clear flow of information. However, the author tries to bring out the real scope of the problem in the introduction. The main aim of positive thinking is to catalyze a transformation in the apprehensions of psychology from obsession with mending the worst aspects in life to a fresh prominence on optimal working of people, collections, and organizations. Thus far, the author has provided little investigation on assimilating the affirmative psychology methodology into schools. The author chose to use Constructivist grounded model case analysis as the in methodology of the research. The author provided a theoretical framework, research background and contributors, course content as well as delivery medium. These factors are usually instrumental in any methodology part of a project. Approaches of data collection, participant observations, field notes, artifacts were also outlined in the research. The data analysis procedure of this research centered on the qualitative records and utilized grounded model data analytic approaches to respond to the research problem. Since the course of classroom teaching was ï ¬ lled with fragmentary dynamic singularities, data was scrutinized and amassed with initial coding all through this study. The determination of this research was to delve totally into the mechanisms of affective edification implementation, and numerous components arose from the data exploration. However, this research provides an in depth exploration as stated above. The author goes ahead to give the reader all the findings that they seek to find. The author finds that, to break the innate social typecasts is expected to be the long-standing undertaking of affective education. This information is probably the best finding that the author has unearthed. This statement is

Organization, people and performance Essay Example | Topics and Well Written Essays - 1750 words

Organization, people and performance - Essay Example The rest of 24% employees are actively disengaged. Thus, employee engagement is very low in most companies worldwide according to the research. For instance, in places like China where staff turnover mostly happens in epidemic proportions, knowing how to build loyalty and engage employees is crucial to the success of Tesco. In light of this, employee engagement is significant to Tesco mainly because it improves employee satisfaction, productivity, retention and recruitment, innovation, and company profitability. First, employee engagement leads to employee satisfaction. According to Beardwell, I., Holden, L., & Claydon, T. (2001), employee’s job satisfaction tends to increase considerably if they are engaged by the company. Subsequently, satisfied employees develop a positive attitude towards the success and performance of the company. Tesco would gain by having satisfied employees since they are committed to the success of the firm. Additionally, their loyalty increases. On a broader perspective, satisfied employees act as ambassadors of the firm. Thus, they support and promote the firm’s brand, mission and strategy. Next, Tesco’s productivity would increase as a result of employee engagement. Robinson, D., Perryman, S., & Hayday, S. (2004) implied that since engaged employees go the extra mile, they lead to increased productivity. Thus, for employees to be top performers, they have to be engaged with the company. As they become more engaged, employee absenteeism reduces while motivation levels tend to increase resulting in increased productivity. In simple terms, the more a firm’s employee is engaged, the more efficient the employee becomes. Lockwood, N. (2007) argued that firms with engaged employees often have their productivity levels increase by more than 43%. Moreover, employee engagement will lead to a low employee

Magnesium calcium lithium, Sodium, and Potassium Essay Example for Free

Magnesium calcium lithium, Sodium, and Potassium Essay In this lab, six different metals were tested for their reactivity in water. From less reactive to most reactive, the metals were as follows: Aluminum, Magnesium, Calcium, Lithium, Sodium, and Potassium. A pattern found in the periodic table explaining the reactivity of metals is the further down in a family, and the further left in a period, the more reactive the metal will be. Aluminum and Magnesium were both the less reactive. Neither of the metals produced hydrogen, or not enough to have a positive test to prove it was there. Metals + H O H + Metal Hydroxide Calcium gave off a large amount of Hydrogen gas. Lighting a splint, placing it in the test tube, and hearing a loud pop proved this. When the calcium was placed in the water, it caused the temperature to rise to such a high level it was not possible to hold with bare hands. This could be because the electrons are moving so quickly that it causes the temperature to rise. The calcium formed a white, powder-like precipitate at the bottom of the test tube. Lithium, Sodium, and Potassium all had very violent reactions in water. Phenolphthalein was added to the beakers after the metals had reacted, and the water turned a pink/ purple color proving that these metals make bases, and therefore have a pH between eight and. Common reactions between metals were they all formed hydrogen gas, even if it was a very small amount. Lithium, Sodium, and Potassium all tested positive to be a base with phenolphthalein, and all had an oily surface. A pattern found in the periodic table explaining the reactivity of metals is the further down in a family, and the further left in a period, the more reactive the metal will be. This is because the elements in period I, Lithium, Sodium, and Potassium, only have one valence electron, and it is quite simple to lose it. Also, the further down the family, the more the ionization energy decreases because of the shielding effect (the inner electrons block the attraction of the nucleus for outer electrons) and atomic radius (the greater the distance between the nucleus and the outer electron). However, the further to the right of the periodic table, the more the ionization energy increase because of the nuclear charge, electron arrangement ( an electron in a full of a half full energy level requires additional energy to be removed), and atomic radius. This explains why Aluminum was the least reactive, and Potassium was the most reactive.

time management Essay -- essays research papers

Time Management   Ã‚  Ã‚  Ã‚  Ã‚  The way a person manages time effects the efficiency of their life. There are many ways that will help in time management. College students for example have many responsibilities. The top priority being school. Students must have time to go to class and show their best of their abilities to finish all work that needed to be done. Some students may have to fit work into their daily schedule. As Rock-Richardson describes,  ¡Ã‚ §As an undergrad, I put my self through two solid years of full-tuition college by working as a daycare provider [ ¡K] ¡Ã‚ ¨ (Rock-Richardson 12). In order to be successful at the tasks the student must eat properly and get enough sleep. The one thing that should be learned is motivation and the famous saying  ¡Ã‚ §Never give up. ¡Ã‚ ¨ If a task must be done and it is felt that there is no time, that is just the misunderstanding of time. The first step in beginning better time management is to write it into an organizer. An organizer is the most helpful notebook a student can purchase. Carol Kanar says,  ¡Ã‚ §Your schedule is the result of the inward decision you make to control events instead of letting events control you ¡Ã‚ ¨ (Kanar 93). For a student to remember important dates such as test dates they must be written down and observed. Major dates to remember are exam dates. There will be numerous tests and assignments during one quarter, which cannot be memorized. This organizing will help in figuring out how much study time the...

“The Destructors” by Graham Greene Essay

Graham Greene the author of â€Å"The Destructors† and Richard Connell the author of â€Å"The Most Dangerous Game† both used a similar mood in their stories. Connell placed his story on an island in the Caribbean that was dark and scary, it had a reputation of death and separation. Greene placed his characters in a post war zone in London where there seemed to be little hope of life. Greene’s setting was urban with many young English boys as his main characters; Connell contrasted that with a sole island with only two main inhabitants and a pack of dogs. Both authors wrote stories that have very troubled characters. The characters also reflect a dark mood to go along with the setting. The Credibility was reasonable for both stories and I believed both stories could happen. Rainsford and â€Å"T† were good characters and the setting a great deal influenced them both. I related more to the atmosphere of â€Å"The most Dangerous Game† but did not have any problem picturing either one while reading the stories. â€Å"The Destructors† took place in London post world war II 1939-1945 on Bank Holiday, which is a 3-day weekend that takes place in Britain a few times a year. â€Å"The Most Dangerous Game† took place on a remote tropical island in the Caribbean and was sometime after the First World War. The first similarity between the two stories is the dark mood that both setting portray, nighttime on an island in the middle of the ocean and post war stricken London. Another similarity is how both setting portray a holiday or vacation idea. The Setting of â€Å"The Most Dangerous Game† is exactly the kind of setting you would need to pull of the kind of â€Å"game† secluded from the day to day bother of other people who might be passing by, no law enforcement to bother you with the accusation of murder. â€Å"The Des tructors† setting is a little harder to believe that this could happen and that a group of kids could pull it off. I have done a lot of demolition and I know how hard it is and how long  it can take. Rainsford was a great hunter even before he got marooned on this island but I’m sure the fact that he was now the prey raised his level of survival necessity. If he was on the island and he needed to rebuild a boat to escape he might not have faired as well but that is only conjecture. With â€Å"T† his character is total based on the setting of the story. If you change the setting you will change â€Å"T† and his whole objective and attitude. The atmosphere or the pervading tone or mood of a place, situation in â€Å"The Destructors† was depressing and dark. I envision rubble and burnt remains of buildings all around with only a few homes left standing in the area. On the Island I see a wonderful tropical paradise that is very inviting although dark and lonely when Rainsford falls from the boat and a wonderful place to visit with lush forest and flowers with sandy beaches. This to me the biggest difference between the two stories, one is set in the busy c ity while the other is secluded. One symbol I see in â€Å"The Most Dangerous Game† is the Island being an image of being alone and needing to survive on your own, one man and his fight against one man. In â€Å"The Destructors† I felt like the symbol was the Wormsley Common Gang against the world or at least against Old Misery. This was a symbol of mans need to sometimes break the rules just because we can get away with it. Greene and Connell both used a similar mood in their stories. Connell placed his story on an island in the Caribbean that was dark and scary, it had a reputation of death and separation. Greene placed his characters in a post WWII zone in London where much hope for the future was lost. The setting for â€Å"The Destructors† was urban with many young English boys as his main characters; â€Å"The Most Dangerous Game† contrasted that with a lonely island with only two main inhabitants and a pack of dogs.
