Abstract
The following paper examines the research provided on atmospheric depletion and its relationship to the survival of humanity. Issues like the greenhouse effect and ozone crisis are discussed. The writer feels strongly towards the serious danger from the pollution that is regularly released into the air and discusses, briefly, ways in which to halt the destructive process.
From the Paper
"One way we are destroying our atmosphere is by releasing carbon dioxide gas. Carbon dioxide makes up part of a natural cycle of carbon involving the atmosphere, land, sea, and plant life (Neal 10). So what is the problem if CO2 is there naturally already? Carbon dioxide makes up a very tiny part of our atmosphere, representing approximately 0.035 percent (Neal 10). 0.035 percent seems insignificant, but consider that a rise of about 0.06 percent changes our atmosphere dramatically (Neal 10). Carbon dioxide is released into the air every time a fossil fuel is burned (Neal 11). Approximately two hundred years ago, the industrial revolution sparked an increase in the burning of the fuels (Neal 11). In fact, my grandparents reside in a small town in South Western Pennsylvania called Allison. This is one of a cluster of small towns in that region. I think that it is safe to say that about eighty percent of the homes in Allison rely on coal as the primary source of heat. Thank goodness for trees and other plants that takes in carbon dioxide and replaces it with oxygen. There lies another problem, though. See, there are not enough trees left on Earth to off set even a small increase in carbon dioxide because rain forests are rapidly disappearing."

Abstract
This paper examines that the Amazon rainforest is an embattled resource being depleted at an alarming rate on a daily basis, which has a global effect. The author points out that the deforestation of the Amazonian rainforest effects the atmosphere by increasing carbon dioxide, which leads to global warming. The paper discusses several perspectives in relation to global warming and the reasons behind the cause behind global warming.
From the Paper
"The Amazon rainforest is an embattled resource being depleted at an alarming rate on a daily basis. The effect of such a loss is not merely local or regional, nor is it limited to Brazil or even the South American continent. The effect is global. Every day, species of animals, insects, and plants disappear from the ecosystem, some of which have yet to be discovered, let alone studied. Even more alarming is the amount of carbon dioxide that is no longer processed from the atmosphere due to the depletion of this resource. If the destruction of the rainforest continues at the present rate, it completely will disappear, a loss that will be devastating for the global environment. The environment is inextricably linked to the world's population."

Abstract
The paper discusses ozone depletion and its causes, including products which introduce chlorofluorocarbons (cfc's) into the atmosphere. The paper also looks at the Montreal Protocol, a recent world resolution regarding the problem of ozone depletion.
From the Paper
"An Antarctic ozone hole forms from September to November each year, caused by man made pollutants that destroy ozone in the atmosphere. The hole has been getting progressively larger. The culprits are chlorofluorocarbons (CFCs), once used as coolants. The ozone hole above Antarctica starts forming in September, when springtime sunlight returns to the polar skies. The light energizes chlorine and bromine containing chemicals that break down ozone molecules in the stratosphere and destroy it. ?Sunlight splits off chlorine from CFCs, and the chlorine ozone reaction takes place most readily on the surface of ice crystals? (Onion). Polar Regions reflects the greatest changes in ozone concentrations, especially the South Pole."

Abstract
This paper examines the issue of ozone layer depletion. The author notes that scientists have detected serious increases in ultraviolet radiation near the earth's surface in recent years, due to the depletion of the protective ozone layer; and discusses why physicians, environmentalists, and governments are expressing concern. The paper concludes that UV radiation causes skin cancers and eye ailments, weakens immune systems, and slows plant growth on both land and sea, and warns that even though steps are finally being taken to protect the ozone layer, it will take many years to repair the damage.

Abstract
The purpose of this experiment was to investigate the scavenging of atmospheric organic contaminants from precipitation, specifically snow and rain. The paper also determined and quantified, from scavenging, the amount of polychlorinated biphenyls and polycyclic aromatic hydrocarbons present in snow and rain. Snow scavenging of organic contaminants was being studied because little is known about this phenomenon and a large amount of precipitation, which occurs in North America, occurs in the form of snow. By studying the various precipitation the researchers were able to observe snow scavenging, the gas scavenging abilities of rain and the particle scavenging abilities of both rain and snow.

From the Paper
"Throughout recorded history, humans have exploited marine resources. One of the earliest known maritime societies occurred along the Baltic Sea approximately 10,000 years ago. These Mesolithic era fishermen did not regulate their fisheries. Because their populations were small, early fishermen did not alter their marine resources. Hence there was never a need for them to constrain their practices. In more recent times, however, the fishing industry has grown to massive proportions. Following the second world war, it took mechanized fleets only 20 years to treble the world's annual fish production. In 1989, the total sea catch amounted to over 86 million metric tons. This increase in fishing, however, has had a devastating effect on the ... "

"The ozone layer is the atmospheric layer that shields the earth from harmful ultraviolet radiation. There is disagreement concerning the extent to which chlorofluorocarbons (CFCs) and other chemicals in the atmosphere attack the ozone layer. Predictions of the resultant ozone depletion occurring globally in the next century have ranged from 3 percent to 18 percent as scientists work to understand this complex problem. Researchers examining the data in search of subtle annual changes in global ozone chemistry noticed that the South Pole's ozone concentration dropped more each October than in other months.? Initially researchers did not believe the data was significant.
Scientists now know that an ozone hole exists over the entire continent of Antarctica every October and has been getting larger each year. The question now is whether this effect is a ..."

Abstract
This paper examines the causes and effects of the depletion of the ozone layer which allows excess ultraviolet light from the sun to leak through and reach the earth's surface. The impact of excess UV light can be increasingly dangerous, harming crops, wildlife and farm animals and increasing the incidence of skin cancer in humans. The paper looks at the life cycle of an ozone molecule, ozone holes and the TOMS (total ozone mapping spectrometer) Earth Probe which can measure the dimensions of an ozone hole. It evaluates the connection between ozone and cancer and provides a timeline for the history of the ozone hole.
From the Paper
"Without the sterner controls on CFC production, ozone-damaging chlorine and bromine levels would have continued to rise steeply until 2100 and beyond. That was the conclusion of the World Meteorological Organization' s 1994 Scientific Assessment of Ozone Depletion, the most comprehensive and authoritative statement to date on the ozone question, prepared with input from NASA, the National Oceanic and Atmospheric Administration (NOAA), and the United Nations Environment Program. It is the product of 295 scientists from both developed and developing countries. Therefore, it represents an overwhelming consensus of the world's scientists about the severity of the threat to the ozone layer."

"Introduction
Local, regional, national and international political decisions can have long-term effects on the ways in which companies conduct business. When public policies, such as those affecting the environment, take a significant departure from their historic orientation, the effect can be devastating to companies and organizations operating under the older guidelines. Yet there are times when public welfare or other compelling interests necessitate significant changes in policy to which business must adapt. This is the case with the 1996 ban on chlorofluorocarbons and the progressive ban on other ozone depleting substances. The scientific community has determined that these substances (commonly used at one time in aerosol propellants and in refrigeration systems) are contributing to the depletion of the ozone layer.."

"Ozone Depletion
The Earth's upper atmosphere contains a layer of ozone. This layer acts to shield the surface from ultraviolet radiation. Ultraviolet radiation can have a variety of adverse effects on living things. Thus, the discovery of diminishing levels of springtime ozone levels high above Antarctica in 1985 caused widespread concern. The cause of this ozone depletion was found to be worldwide industrial production of chloroflourocarbons (CFCs). In response to this environmental threat, the world's governments gathered to discuss possible solutions. The result was an international treaty called the Montreal Protocol. This agreement calls for gradual reductions in global CFC production. It also provides for periodic reevaluation of the problem based on new scientific evidence. Considering recent studies which indicate that ozone depletion.."

"OZONE LAYER DEPLETION AND ITS EFFECTS
Introduction
The ozone (O3) layer of the Earth's upper atmosphere exists from 50,000 to 120,000 feet (10:2127). Ozone at this level of the earth's atmosphere is generated by the absorption of ultraviolet radiation by oxygen (O2). In forming ozone, ultraviolet radiation of wavelengths between 290 and 320 manometers is absorbed and thus not allowed to reach the surface of the Earth. Concentrations of ozone are a few parts per million, variously estimated between 5 and 10 ppm (10:2127). Unstable ozone molecules are also constantly being created and destroyed by complex natural forces involving solar radiation and interactions with very minute quantities of other gases. Ozone concentrations fluctuate naturally on a daily, seasonal, and ..."

From the Paper
"The world's ocean fisheries are being depleted. Currently, the world's major fisheries are sustainable and renewable if conservation measures are begun. The culprits are over-fishing, wasting of fish, and environmental changes. The oceans have a history of recovery from mass extinction. About 235 million years ago, there was a massive fish die off which killed approximately 96 percent of the fish in the sea. 1 The fish at that time were able to repopulate the oceans. There is every reason to believe that the world's fisheries will recover from their presently reduced biomass if the mortality rate from fishing is reduced.
In 1950, the world's fishermen caught 20 million metric tons of seafood.2 By 1990, the world's fishing fleets were catching 84 million metric tons of fish which they brought into port and..."
