Depletion of the Ozone Layer
The issue of whether the people of the world have exaggerated the threat of the ozone
depletion has been widely debated. It is an important issue because it concerns health
and well being now and tomorrow. A variety of different arguments have been put forward
about this issue. Because air pollution is greatly affecting the ozone, America needs to
take immediate steps to stop ozone depletion. This essay will examine different arguments
concerning the ozone layer.
Ozone is a highly irritant gas, which is formed in our atmosphere in the presence of
sunlight from other air pollutants, including nitrogen oxides and hydrocarbons. These
"precusor" pollutants, which cause the formation of ozone, are emitted by pollution
sources. The adverse health consequences of breathing ozone at levels below the current
U.S. National ambient Air Quality Standards (NAAQS) of 120 parts per billion are serious
and well documented. Observational epidemiology studies have shown compelling and
consistent evidence of adverse effects by ozone below the current standards. Considering
the published results from various cities, the EPA analysis under predicts the
respiratory hospital admission benefits of their proposed regulations. Airway
inflammation in the lung is among the serious effects that have been demonstrated by
controlled human studies of the ozone at levels typically experienced by most Americans.
Exposures to ozone and particulate matter air pollution have been linked to medically
significant adverse health effects. The current NAAQS for these pollutants are not
sufficiently protective of public health. Both the ozone and particulate matter standards
have vast implications for the equality of life and the economy of the United States. The
vast majority of Americans support improving and enhancing the quality of their life by
eliminating or decreasing air pollution. Americans are quite willing to shoulder the
burden of clean air. The Environmental Protection Agency and the U.S public and

Depletion of the Ozone Layer Essay

- Depletion of the Ozone Layer The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the sun’s ultraviolet radiation to reach the Earth’s surface. In particular, it will be the increase of UV-B rays which will have the most negative side effects....   [tags: Papers]

Depletion Of The Ozone Layer Essay

- 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 nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found t...   [tags: essays research papers]

depletion of the ozone layer Essay

- Our Radiant Planet: Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that would otherwise reach our planets surface....   [tags: essays research papers fc]

Essay on Global Warming and the Depletion of the Ozone (O3) Layer

- Global Warming and the Depletion of the Ozone (O3) Layer The average surface temperature on Earth has increased approximately 1.0°F in the past century, and it is projected that it will again increase somewhere two and nine degrees by the year 2100. This is the expected effect of increased greenhouse gases, which contain the Sun's energy (heat) in the lower atmosphere (troposphere). Much of the increase in these gases can be considered a natural occurrence, however, at least some of it is human induced....   [tags: Environmental Greenhouse Gases]

Essay on Ozone Layer Depletion

- Ozone Layer Depletion Ozone is a natural trace component of the atmosphere. It is created continuously through the action of sunlight and oxygen in the upper atmosphere. At the same time this destroyed by various reactions with other components in the air. The next result of these natural processes is the so-called ozone layer in the stratosphere at altitudes between 15 and 50 kilometers in which the concentration of the ozone is raised. Ozone is a colorless gas, a form of oxygen. However, an ordinary molecule of oxygen contains two atoms....   [tags: Papers]

Environmental Crsis on Earth Essay

- The earth is facing an environmental crisis on a scale unprecedented in human history. This crisis is due to high levels of human pain and, if it continues, the human life on the planet disappears. People often say that the reason that the world is in its current state is because there are too many people or because of modern technology. Global pollution growth has led to increasing pressure on worldwide natural resources including air, water, land, and raw materials; and modern societies have generated an increasing demand for the use of industrial chemicals....   [tags: Ozone Layer Depletion, Global Warming, Pollution]

Ozone Depletion and Industrial Output Essay

- Ozone Depletion and Industrial Output For years, we have heard about the ozone crisis: that because of industrialization and the lack of pollution-consciousness by our industries, governments, and academia, we have put so many environmentally harmful products into the atmosphere that our ozone – the good kind, the kind that protects us from harmful UV radiation – is becoming dangerously damaged. It is becoming thinner and developing holes, like the large hole over Antarctica. Predictions made expected the ozone hole to continue to increase and for the general thickness to get continuously thinner, so that the harmful UV rays of the sun would pass right through our atmosphere an...   [tags: Ozone Layer Environmental Essays]

Global Effects of Ozone Depletion Essay

- Global Effects of Ozone Depletion Ozone depletion in the earth’s atmosphere is under constant scrutiny by the American press and people. Perhaps the concern is warranted; the ozone layer protects life on earth by absorbing 97-99% of the damaging ultraviolet radiation from the sun (U.S. Environmental Protection Agency, 2006). Over the past twenty years, the stratospheric ozone has decreased approximately 3% per decade. Possible concerns have been raised about loss of polar caps, DNA damage, increased human health risks, and environmental process disturbance....   [tags: Environment Ozone Layer Essays Papers]

Essay Ozone

- Ozone Ozone (O3) is a molecule consisting of three oxygen atoms, similar to the oxygen we breathe (O2), however oxygen consists of only two oxygen atoms. In the stratosphere, a region high up in the upper atmosphere, light rays are responsible for the breaking down of oxygen (O2), breathable oxygen into its two separate oxygen atoms. Lone oxygen atoms are markedly reactive. When a lone oxygen atom comes into contact with a breathable oxygen molecule (O2) it combines to form ozone (O3). The ozone layer is a small residual amount of ozone concentrated in a band in the upper atmosphere....   [tags: Ozone Layer Oxygen Environmental Essays]

air. We will have achieved only marginal effects by decreasing the current ambient air
quality standards from120 parts per billion to 90 parts per billion. The nature of the
dose-response relationship is such that reduction to much lower levels may be necessary
to result in the abolition of detectable health effects from ozone standards and
strategies, the highest quality research is needed.
