Development of the phenomenon occurred parallel to the increase of the atmospheric chlorine content produced by the emission of CFCs.
These gases absorb the terrestrial radiation and send back to the earth. If we will look at the model of ethical consumerism in which gross domestic product is more focused on quality of life, firms will transform its character to corporate social responsibility, from mere consumers to ethical consumption and capital to social responsible investment.
This gives a higher risk on the survival of the entire human race. After the discovery of CFC problem in mid seventies, ozone destruction by active chlorine lO has become a dominating question.
Ozone works like an umbrella and protects from the harmful UV radiations coming from cosmic rays to earth. In the United States National Academy of Sciences released a report concluding that the ozone depletion hypothesis was strongly supported by the scientific evidence.
Laboratory studies have also shown that fluorine and iodine atoms participate in analogous catalytic cycles. Rowland inboth received the Nobel Prize in Chemistry for doing the research in atmospheric chemistry according to Grujl and van der Leun Today, we have several means of addressing the issues, it is not just about identifying the problem, the cause of the problem but it is also important that the ethical economical, social and political aspect of the issue is being discussed.
The reactions deplete ozone layer. Ozone-oxygen cycle and Ozone depletion Importance to surface-dwelling life on Earth[ edit ] Levels of ozone at various altitudes and blocking of different bands of ultraviolet radiation. And it is important that no matter what the expenditures in protecting the environment, it is necessary to stress on prioritizing the issue.
The carbon dioxide allows incoming solar radiation to enter into the earth surface but it absorbs the terrestrial radiation and sends back to the earth.
Moreover, the polar vortex formed over Antarctica is very tight and the reaction occurring on the surface of the cloud crystals is far different from when it occurs in atmosphere. Similarly, horizontal convection currents are also generated on the ground surface.
The London amendment to the Montreal Protocol was signed in May and came into effect on 10 August, CFCs released up to amount to 15 million tones. It filters out all radiations below A0 UV-B radiations that are biologically harmful, and controls the heat budget of the earth.
By absorbing UV radiation the ozone layer heats up the atmosphere.Ozone Depletion Essay Sample.
INTRODUCTION To give emphasis on the discussion of this paper, it is best to define first the meaning of ozone, ozone layer and other related words that we will encounter during the course of our discussion.
Ozone depletion describes two related events observed since the late s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.
Ozone is a powerful oxidant (far more so than dioxygen) and has many industrial and consumer applications related to oxidation. This same high oxidising potential, however, causes ozone to damage mucous and respiratory tissues in animals, and also tissues in plants, above concentrations of about ♠ ppm.

Introduction to Atmosphere: The atmosphere is a turbulent gaseous blanket that surrounds the earth. The mass of this surrounding atmosphere is less than a millionth part of that of the whole earth, yet its activities and influences are far-reaching.
Ozone Depletion The ozone layer is a specific area in the stratosphere of maximum ozone concentration. Ozone in the stratosphere forms naturally and protects us from damage that can be caused by solar radiation such as skin cancer. Ozone Layer Essay; Ozone Layer Essay.
The Layers of Research Design. 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 .Download
