प्रश्न
Discuss in detail the process of ozone depletion.
उत्तर
The upper part of stratosphere contains large amount of Ozone gas. The ozone gas blocks the harmful ultraviolet rays reaching earth. It has been proved that chlorofluorocarbons or CFC are released from the refrigeration system, air conditioning systems, spray cans etc. These CFC’s are light and are able to reach at height of stratosphere. Here they react with the ozone gas. In this process the chlorine gas is released which reacts with the ozone gas. It breaks apart the ozone molecules thus reducing them in the stratosphere. As a result, the ultraviolet radiation is able to reach the surface of earth. These rays can cause skin cancer, cataract and affect the immune system of the body.
