The depletion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before (because of the major increase in the population), there is a major concern that we create less pollutants to help conserve the ozone layer. In this research paper I will give vital information on how …showed first 75 words of 2697 total…

Hydrochlorofluorocarbons were put to use because they cause less damage to the ozone layer. NASA also helped in the effort by launching the seven-ton Upper Atmosphere Research Satellite into orbit in 1991. It measured ozone variations at different altitudes. Due to this and many other measures taken, the spread of many ozone depleting chemicals has been greatly reduced.
