- 301: Ozone Depletion
- ... the bottom of the food chain, placing us in extreme danger (Goldfarb 288). Henry Lee, leading researcher on ozone depletion for the Environmental Protection Agency (EPA), says that UV rays will only have a slight effect on oceans, though. He says the problem lies on the fact that 70 percent of the Earth's surface is covered with water, making it a widespread problem. In addition to that, humans exposed to ... the job done, but cause less damage (Singer and Crandall npg). Hydroflurocarbons (HFC's) are "made with hydrogen instead of chlorine," which doesn't contribute to the ozone problem, but is a factor to the greenhouse effect (Goldfarb 290). Hydrochloroflurocarbons (HCFC's), like HFC's, have hydrogen in place of the deadly chlorine, but still contribute to ozone depletion. The only difference being HCFC's deplete at a much slower rate ( ...
- 302: Flooding
- ... and a lead author of the recent IPCC Regional Assessment of Climate Change. In an overview of the future impacts of global warming he said average global temperatures are rising consistent with the buildup of greenhouse gases. The warming is not uniform: the eastern United States has actually cooled slightly because it is beneath a cloud of sulfates resulting from combustion of high-sulfur coal. Moreover, satellite observations show that temperatures ... in less developed areas.” More dunes are being enhanced, he said, more houses are being moved back. There are many small successes, and many small victories add up to big victories. In remarks about the effect of sea level rise on birds, Joanna Burger of Rutgers University expressed some skepticism about whether global warming is actually occurring. But assuming it does, she indicated sea level rise affects birds in their many ... Atlantic coast will take care of themselves, he said. He commented that overwash of the barrier islands has benefits: new wetlands which are younger and more productive develop on the back of the barriers, an effect lost if barrier islands are stabilized. While revetments are better than bulkheads, he said neither are as good as natural marsh edge. He expressed reluctance about endorsing raising the land level one inch every ...
- 303: The Environmental Impact of Eating Beef and Dairy Products
- ... during the past half century. Cattle ranching has also been linked to Global Warming. The grain-fed-cattle complex is now a significant factor in the emission of three of the gases that cause the greenhouse effect- methane, carbon dioxide, and nitrous oxides- and is likely to play an even larger role in Global Warming in the coming decades. The burning of fossil fuels accounted for nearly two- thirds of the 815 ... To sustain the yearly beef requirements of an average family of four requires the use of more than 260 gallons of fossil fuel. Finally; Nitrous Oxide, which accounts for 6 percent of the global warming effect, is released from fertilizer used in growing the feed; and methane, which makes up 18 percent, is emitted from the cattle. The final victims of the world cattle complex are the animals themselves. Immediately ...
- 304: Fusion 2
- ... energy input. If the plasma energy loss is too large, then ignition cannot be achieved. An unavoidable diffusion of energy across the magnetic field lines will occur from the collisions between the particles. The net effect is to transport energy from the hot core to the wall. This transport process, known as classical diffusion, is theoretically not strong in hot fusion plasmas and is easily compensated for by heat from the ... D-T fusion, might make up a "second generation" of fusion reactors). Finally, a fusion reactor would not release the gaseous pollutants that accompany the combustion of fossil fuels; hence, fusion would not produce a greenhouse effect. The fusion process has been studied as part of nuclear physics for much of the 20th century. In the late 1930s the German-born physicist Hans A. Bethe first recognized that the fusion of ...
- 305: Pollution Getting The Best Of
- ... environment. It is a major problem in America and as well as the world. Pollution not only damages the environment, but damages us also. It has caused many problems ranging from lung cancer to the greenhouse effect. It is all among us and yet we continue to live in our own filth. What is the reason behind this flawed logic? The cars we drive, our left over trash, and the businesses we depend on are to blame. Automobiles are undeniable the greatest source of pollution. The noise pollution created by cars is immense. Another polluting effect of cars is the heat it creates. This heat makes it unpleasant to be near the car while its running. And of course the most famous of the automobiles evils is the exhaust. The ...
- 306: Why Drugs Should Be Legalized!!!!
- ... marijuana, a basically harmless drug. One must also consider the economic possibilities that accompany the decriminalization of drugs. The nation's GNP (Gross National Product) only counts legal transactions. If drugs were legalized, a significant effect could be seen on the GNP helping to make our economy stronger in relation to other countries. Profits could be taken out of the drug dealers hands and into the hands of an honest entrepreneur ... one must look at what marijuana and hemp can do for our society. When posed with the question, "if you could have any choice, what would be the ideal way to stop or reverse the greenhouse effect?" Steve Rawlings, the highest ranking officer in the U.S. Department of Agriculture, responded, "Stop cutting down the trees and stop using fossil fuels." The problem that Rawlings foresaw was the lack of a ...
- 307: Scarlet Letter Critique -
- ... of human beings. The next major theme fits into the first. It is an individual vs. society idea; Hester and her lover, Dimmesdale, become fugitives of the law of Puritan society. The next is the effect of sin, whether good or bad, on the novel s major characters. The final major theme is the public vs. private self. It shows that people are much, much different in the public than they ... whether good or bad, on its characters. The Scarlet Letter is, in a sense, a study of the effects of sin on the hearts and minds of Hester, Dimmesdale, and Chillingworth. In every case, the effect is devastating. Once these characters stumble into evil, it keeps a strong grip on them, and they are not able to separate themselves from it. Sin changes the sinners. It darkens their vision and weakens ... and the ones they are involved with. Pearl is very symbolic of a sign or medal that hovers over Hester, even worse then the scarlet letter does, that never lets Hester escape sin, and the effect of this on Hester is excruciating. Sin should always be in the mind of the reader while reading The Scarlet Letter, and they should always try to see for themselves how sin effects the ...
- 308: Women In Combat
- ... my second sub-topic by comparing men and women physically then comparing men and women psychologically. Then I will evaluate the health care needs of women in combat support units. Finally I will discuss the effect that women would have on unit cohesion. After discussing how these aspects can affect the effectiveness of the military, I will draw conclusions as to how these factors connect to the affects of allowing women ... factors, which I used to compare men and women psychologically. I discussed how males are perceived to be more aggressive than females, the stress that males and females will face in combat, and female's effect on unit moral. Also I showed how important unit cohesion was in determining a units effectiveness. The health care needs can be met by combat support units when there are well trained physicians and nurses ... Society, 1996, p. 17). Male and female soldiers were asked questions about how they felt their unit performed in the field. "The study showed that the proportion of women (up to 35%) had no significant effect on the operational capabilities of the unit." (Armed Forces & Society, 1995, p. 17). DISCUSSION Unit-cohesion is the commander's responsibility for his unit. As the above survey shows men and women can interact ...
- 309: Movie: Twelve Angry Men
- ... difficulties and how they overcome them. First, we will apply the Johari grid theory and see how it applies to their situation. Then, we will see how each individual's frame of reference and prejudices effect their perception which cause difficulties in the communication process. If we analyze the Johari grid of each juror we see a large hidden area in the case of all of the men. Take into consideration ... same for each juror before beginning the deliberation. It is the size of the unconscious area that will differ more among the men. We will see how the contents of the unconscious area will largely effect the decision making process of some of the jurors. Because the information contained in the unconscious area is unrecognized it is often the most difficult to overcome. Henry Fonda's (Juror #8) interpersonal style would ... it. The net result is a large blind area. He is unwilling or unable to level with the others and is also unreceptive to any feedback. Most likely the extent of these feelings and the effect it has on his perceptions is unconscious to him. Eventually, he finds himself the only one maintaining a vote of guilty. He feels his sense of reality is in question and it threatens him. ...
- 310: Mark Schaller's Study About Fame
- ... twenty seven years old. Cobain's attitude changed. He started to suffer from depression even though he was rising in fame. His social behavior was not the same. Cobain was also addicted to drugs. In effect, both the physical and mental aspects of his self were deteriorating. According to Schaller(1997), Cole Porter achieved his fame around the year 1930. Porter, like Cobain, seemed to suffer from depression. Schaller mentions that ... be changed. Referring to Ackerman's studies, a person that is more self-conscious because of their obtainment of fame could have a negative self-concept causing the downfall of personality, achievement and interests. In effect the person would become self- destructive. This method of explanation for the reasoning behind a famous persons self-destruction is that the person becomes overly self-conscious. Another approach to the reason why fame may effect personality and social behavior and finally lead to self-destruction is shyness and social anxiety. Ron Norton, Brian Cox, Paul Hewitt, and Lindsay McLeod(1997) explained how social anxiety can be associated with certain ...
