  • Depletion Of The Ozone Layer - 1,052 words
    Depletion of the Ozone Layer Depletion of the Ozone Layer CHEM 151 Research Paper July 11, 1996 The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitr ...

  • Ozone Depletion Is An Environmental Problem That Many People Do Not Take As Seriously As They Should The Ozone Layer Prot - 1,074 words
    Ozone depletion is an environmental problem that many people do not take as seriously as they should. "The ozone layer protects animal and plant life from the sun's harmful radiation. The depletion of the ozone layer will allow ultraviolet rays to, over time, lead to higher skin cancer rates, eye cataracts, and crop damage." At ground level, ozone, a form of oxygen, is poisonous to humans and other organisms. It causes respiratory problems and damages plants. The greatest concentration of ozone is located in a layer of air called the stratosphere, some 10 to 30 miles above the Earth's surface. About 90% of the Earth's protective ozone layer resides in this level. "The molecule, ozone, is pro ...

  • Ozone Layer - 1,860 words
    Ozone Layer Some scientists have proclaimed that the human race is slowly depleting the layer of ozone which protects us from ultra violet light. In reality, humans have very little control of the world in which we live. Scientific evidence has shown that there is very little depletion in the ozone layer and the contributions the human race makes towards this depletion is and always will be insignificant compared to nature. The theories of the depletion and what it would cause are flawed and contradictory. Where and when did this global killing threat begin? It all began in the mid 1960's when the United States government began pursuing super sonic transports. These would be planes which wou ...

  • Ozone Layer Depletion - 1,142 words
    Ozone Layer Depletion The Potential Effects of a Depleted Ozone Layer And God said, let there be light and there was light and then God saw the light, that it was good ( Genesis 1: 3-4 ). Undoubtedly, light is good. Without light man could not survive. Light is the ultimate cosmic force in this universe allowing man to progress and flourish. In the form of heat, light from the sun warms the Earth. Light, also, is the single most important factor influencing the growth and development of plants. Photosynthesis, a process by which plants incorporate light from the sun, allow plants to botanically grow and survive. Certain forms of light are harmful and thus can be said are 'bad'. A natural umb ...

    ... re available to man, than being mostly confined to polar water regions, another principal food resource could be added to man's long list of them. Another important feature involved in a decline in phytoplankton numbers and productivity is the fact that phytoplankton helps produce and recycle the world's oxygen supply ( Bowermaster et al, 1990, p.40 ). An increase in ultraviolet light can thus endanger an entire ecosystem without necessarily killing off the masses. By altering the respiratory balance in an ecosystem a variety of species would be affected. Furthermore, the same oxygen recycled by phytoplankton is breathed by all animals and man himself thus adding to the importance of the ...

  • Ozone Layer Poisoning - 1,109 words
    Ozone Layer Poisoning The poisoning of the Earths ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozones depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increasing with every second; moreover, there are many ways we can help reduce the problem and preserve the ozone layer. Ozone is a pale blue gaseous form of oxygen, in chemical form it is ...

    ... diation could get so high that it may start burning trees and eventually forrests, in the process destroying our sources of oxygen that we need to survive. The increase in radiation will start to diminish crops and other food sources. Starting with the depletion of the ozone layer, the domino effect of the extinction of biological systems on Earth would continue to plants and then on to the marine ecosystem. The effects of poisoning of the ozone layer will lash out on the marine ecosystem. The marine ecosystem would severely suffer from the thinning ozone and the increase exposure to ultrviolet radiation. Starting with phytoplankton, the foundation of acquatic food chains, would loose th ...

Plausible mechanisms include heterogeneous chemistry on sulfate aerosols [which convert reservoir chlorine to active chlorine - R.P.] and the transport of chemically perturbed polar air to middle latitudes. Although other mechanisms cannot be ruled out, those involving the catalytic destruction of ozone by chlorine and bromine appear to be largely responsible for the ozone loss and are the only ones for which direct evidence exists .

    A Fairy Tale A fairy tale. Ruby Red, a tale of deceit By Robyn Smith The winter in Argroutsmere had always set on early. It was October, all hallows eve and winter was already here, infact one of the coldest that this small quaint kingdom had ever seen. The trees turned to glass, their branches heavy in a frozen ache, layer upon layer of feather light crystals had gracefully drifted and floated from the heavens, to make this land as pure and white as above. The bear tracks below filling in slowly, the owner long passed. A blanket of fleece covered the earth, a barrier between warmth below and harsh cold above.

    ... had little wish to draw him into this conversation. I decided to change the subject quickly. "Coincidentally, yes sir. Why I'm calling, though, is to inquire about the number of outboard motors that have gone missing since last week." "Pardon me?" The tone of his voice took a sudden sinister turn that sent a twinge through my bladder. Like the rookie I was, I had made some as yet unrecognized blunder. I felt the strong urge to conclude the interview immediately, but it was too late. He knew my name. He knew my brother's name. He knew why I'd called. He knew everything. I'd have to bluff past my own ignorance. "Well, I was wondering if the police suspected some kind of theft ring being i ...

  • A Parasite Is Defined As An Organism That Lives In Or On Another Organism, Called A Host 2 If The Parasite Has The Capacity T - 1,538 words
    A parasite is defined as an organism that lives in or on another organism, called a host (2). If the parasite has the capacity to cause disease in the host then the parasite is called a pathogen. Disease in the host is caused by the infection of the parasite. The interaction between the host and parasite is complex. Both the pathogen and the host strive for survival in some of the cases. The pathogen divides within or on the host in an attempt to keep its species alive while the hosts defense mechanisms simultaneously attempt to eliminate the pathogen. The extent of the battle for survival varies depending on the relationship. This paper discusses the disease state of Chlamydia; how the orga ...

  • A Study Of Catholicism - 592 words
    A Study of Catholicism A Study of Catholicism When "catholic" is used as an adjective, it means universal, open or general. I have read art magazines and reviews that have described certain art collections as "catholic in its uniqueness." The fact that Catholicism has its root in the word "catholic" is not a coincidence. In his essay "Catholicism: A Synthesis," Richard McBrien says that it is this notion that distinguishes Catholicism from other religions, Christian and non. The notion is that Catholicism is a religion that is based on open-mindedness. McBrien alludes to flags to clearly define his thesis. Many flags of the world share the same three colors. He uses the colors red, white, an ...

    A Valediction: Forbidding Mourning A Valediction: Forbidding Mourning Although the subject matter of A Valediction: Forbidding Mourning could be applied to any couple pending separation, John Donne wrote his poem for his wife on the eve of his departure for France in 1611.In the poem, the speaker pleads with his lady to accept his departure. The speaker defines and celebrates a love that transcends the physical and can therefore endure and even grow through separation. In arguing against mourning and emotional upheaval, Donne uses a series of bold and unexpected comparisons for the love between the speaker and his lady. Donne makes his first surprising analogy in the first stanza when he com ...

    A Valediction: Forbidding Mourning Intro to Poetry Oct 10 2000 Interpretation of A Valediction: Forbidding Mourning Although that it may seem that the meaning of A Valediction: Forbidding Mourning could be applied to any couple awaiting separation, according to Izaak Walton, a seventeenth-century biographer, John Donne wrote his poem for his wife, Anne Donne, right before his departure for France in 1611 (Damrosch 238). However, even though the poem is not written to an audience, many of us can learn from what Donne is trying to convey to his wife. In the poem, Donne pleads with his lady to accept his departure. He defines and celebrates a love that transcends the physical realm and expresse ...

    Acl Injuries In Athletes ACL Injuries in Athletes The Anterior Cruciate Ligament (ACL) attaches the femur, which is the thighbone, and the tibia, which is the shin, together (northstar). A torn ACL is one of the most excruciating experiences in an athletes life. It is the first thing that comes to mind when they hurt their knee on the field; for many it is their greatest fear. A torn ACL can sometimes mean the end of an athletes career. It can mean losing the chance to get that scholarship for young athletes, and it can also mean the end of those million dollar paychecks for those who have gone professional. A torn ACL can result in numerous surgeries, months of vigorous exercise and rehabil ...

Many locations give the test for free. You can choose between anonymous tests, in which you do not give your name to the HealthCare provider, or confidential tests, in which you do give your name. Test sites should provide trained counselors who can offer you support and guidance, no matter what the test result.(Balch-97) An HIV test looks for the antibodies your immune system creates in response to the virus. These antibodies may not appear in your blood until three to six months after HIV infection. Therefore, ...

    Air Pollution Air Pollution is addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally. Air pollution makes people sick, it causes breathing problems and promotes cancer, and it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life. Pollution is changing the earth's atmosph ...
