=Ozone Layer recovery could be delayed by 30 years= [|BBC News] October 12 2017

A study found that chlorine-containing chemicals, mainly produced in Asia for paint stripping and manufacture of PVC, would slow the progress made in healing the ozone layer for 30 years. Some of these chemical are dichloromethane and dichlorethane. Also, last year scientist had found that the thinning of the protective ozone layer was diminishing. Scientist believe for a long time that these compounds would decay soon, however, they are now considered the main factors that damage the ozone layer. These chemicals are exposed to the eastern Pacific from factories in Asia and from there uplifted into the stratosphere. Although the workers ensure there is no leakage, new study said that fugitive emissions are happening and could damage the ozone layer badly. Because they can not only affect the lower atmospheric ozone but also transport to stratosphere and destroy ozone effectively. They predict that ozone recovery date would delay from 2050 to 2080.
 * Summary**

In our Ap Environmental course, we had learned about the ecosystem and its general structures (Miller 84-85) including atmosphere, consisting of troposphere and stratosphere. We know that the lower portion of stratosphere contain enough ozone to filter out most of the sun's harmful ultraviolet radiation, allowing living organisms to exist on land and in the surface layers of bodies of water. This article talks about the damage of ozone layers caused by chlorine-containing chemicals and how effectively the damages are.
 * Relation of Course**

After reading the article, I strongly believe that although there are conflicts within scientist about whether these overlooked chemicals will actually affect the stratosphere we definitely need to pay attention to these short-lived chlorocarbon chemicals. There should be clarified laws stating the maximum chlorine-containing chemical levels emitting to the environment from factories. It is not too late to realize the harmfulness of these chemicals and everyone should take responsibilities to find the best solution to solve this environmental issue. This article also emphasizes the importance of maintaining a stable, unaffected ecosystem and effective actions to reduce anthropogenic destructions. If the ozone layer are damaged, the life forms on earth will be affected greatly and might cause irreversible destructions because the harmful ultraviolet radiation
 * Opinion**

This article related to the Pollution Prevention Act of 1990, which stated that Congress declares pollution should be prevented, products recycled, and if neither is feasible, it should be taken care of in an environmentally safe manner. This act may be enhanced in the future and include that emission/ pollution should be tested regularly and based on those results decide whether a chemical is hazardous or not and do further improvements.
