  • A Reaction To Clive Pontings A Green History Of The World - 1,810 words
    A Reaction To Clive PontingS A Green History Of The World A Green History of the World has been very educational reading and has given me a new prospective on the environment. While I do disagree with some of Clive Pointings views I have learned a lot from his work. A Green History of the World was a very in-depth look at the past and the future of our environment. Pointing raised my consciousness regarding the trials we face as inhabitants of this great planet and left me with some food for thought. After reading Chapter One I found myself entranced by the mystery of Easter Island and excited about the information A Green History of the World had to offer. I had virtually no understanding o ...

Osmoregulation is the process of maintaining the delicate balance of salts and minerals in their tissues. For freshwater fish, maintaining osmoregulation is key in their survival. Acid molecules, which are a result of acid rain in the water, cause mucus to form in the fishs gills. This in return prevents the fish from absorbing oxygen. If the fish are unable to absorb oxygen, the consequence could be the eventual suffocation of fish and the low pH could throw off the balance of salts in the fish tissu ...

  • Acid Rain - 1,774 words
    Acid Rain What is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by the pH of pure water in reaction with atmospheric concentrations of carbon dioxide, resulting in carbonic acid. These particles partly dissociate to produce hydrogen ions and bicarbonate ions ...

  • Acid Rain And North America - 1,891 words
    Acid Rain And North America In the past century, one of the greatest threats to North America's aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems, as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain, and what can be done to improve North America's water quality and prevent future catastrophes? To answer these questions, we must first examine the cause and formation of acid rain, as well as understand ways to decrease or prevent its formation. Formation of acid rain. Acid deposition, mo ...

  • Acid Rains - 540 words
    Acid Rains Acid rain refers to all types of precipitation--rain, snow, sleet, hail, fog--that is acidic in nature. Acidic means that these forms of water have a pH lower than the 5.6 average of rainwater. Acid rain kills aquatic life, trees, crops and other vegetation, damages buildings and monuments, corrodes copper and lead piping, damages such man-made things as automobiles, reduces soil fertility and can cause toxic metals to leach into underground drinking water sources. Rain is naturally acidic because carbon dioxide, found normally in the earth's atmosphere, reacts with water to form carbonic acid. While "pure" rain's acidity is pH 5.6-5.7, actual pH readings vary from place to place ...

Furthermore, every time the trout moved, it always returned to the same position it left from. Conveniently, the trout may have used the three stones at the base of it's schooling position as a marker Also, the school showed something that resembled a hierarchy of order. It appeared that the larger fished floated toward the bottom, while the smaller fished floated at the top. During the observation period, the fish dispersed in a rapid manner on three occasions. On the first random dispersement, no significant signal was apparent. However during the second rapid dispersion! ...

  • Animals And Humans - 733 words
    Animals And Humans 1. There is an enormous different between the life of humans and other animals. First of all, humans are clearly at the top of significance for the simple reason that they are at the top of food chain. This is what allows people to dictate society. Combine this with the fact that humans have the ability to reason, and it is clear that people have more of a significance. It is as simple as this, no other species as the ability to end the entire world with tools which they have created. The purpose of human life is to strive to your calling. Obviously, this is a vague and general statement. That is because every single person lives their lives in a different light. A person ...

  • Are Humans Animals, Or Are They Something More - 1,176 words
    Are Humans Animals, Or Are They Something More? Human beings should be more than animals, but are they really? In Republic, by Plato, Antigone, by Sophocles, The Aeneid of Virgil, by Virgil, and On Justice Power and Human Nature, by Thucydides, it seems as though human beings really are nothing more than animals. Animals are thought of as not caring about anyone but himself or herself. It is survival of the fittest, if you are not strong enough, someone else will take your place. Human should be caring for other human beings, if someone is in trouble, another human should help them. This is not the way it is in these 3 works. Humans dont care about anyone but themselves, they kill so they ca ...

  • Bears Beware - 892 words
    Bears Beware subject = Environmental Issues title = Bears Beware In our world today many animals and plants are loosing their fight against human intervention in their once well-balanced ecosystem. We are all aware of the extinction of the dinosaurs and the dodo birds, however most people do not realize that annually thousands of species of our flora and fauna are now becoming extinct. This on going trend is increasingly threatening our bio diversity and global ecology. To give a specific example of animal depletion I will focus on Canadian bears. The following factors are responsible for their decline. Hunting, loss of habitat, and just plain apathy on part of the public to preserve the bio ...

Saw them cut in two by machine-gun fire saw them plead to God and their mothers for help. He got it all, survived, and never became hooked on the so called glory and romance of war photography. (13, 14 Waller) I noticed that a lot of books and movies about war or the army have soldiers pleading for their mothers and I saw a movie, G. I. Jane, that reminded me of this whole paragraph. Robert Kincaid pulled a pack of cigarettes from his shirt pocket, shook one halfway out, and offered it to her. For the second time in five minutes, she surpris ...

  • Boundaries Of Ownership - 2,946 words
    ... Court decision in an earlier case. Blackmun, treading carefully along a fine line between the different kinds of rights accorded to different kinds of owners, stresses that infringement of copyright does not easily equate with theft, conversion or fraud. . . . The infringer invades a statutorily defined province guaranteed to the copyright holder alone. But he does not assume physical control over the copyright; nor does he wholly deprive its owner of its use. While one may colloquially liken infringement with some general notion of wrongful appropriation, infringement plainly implicates a more complex set of property interests than does run-of-the-mill theft, conversion or fraud.

  • Cheetahs - 1,037 words
    Cheetahs Cheetahs have been evolving and adapting themselves to the deserts of the Serengeti for many years. However, cheetahs have never been common in the wild, but they're now in grave danger of becoming extinct, due to loss of habitat, high infant mortality, and hunting by humans for hides. Cheetahs can and should be saved because they have a difficult time surviving on there own due to poor parenting skills, cub mortality, and energy demands. The cheetah is also a very important part of the ecosystem and will be disrupted if the cheetah becomes extinct. Saving the cheetah is very important for their niche as well the niche of others. This amazing creature needs to be saved. There are ma ...

  • Cosmogony - 1,112 words
    Cosmogony What is cosmogony? Cosmogony can be defined as a study of the physical universe in terms of its originating time and space. In other words, cosmogony is the study of the universe and its origins. The origin and the nature of the universe have been one of the most debated topics throughout history. Both the scientific and theological communities have yet to ascertain a common ground on how the universe came into being and whether it was an act of "God" or merely a spontaneous and random phenomenon. New discoveries in the scientific world provide new viewpoints on the creation of the universe and its relevance to a supreme intelligent "Creator." Due to mankind's constantly changing p ...
