Answer 1

Answer 2

$\Large{\underline{\underline{\bf{Depletion\: of\:Ozone \: Layer:-}}}}$

Ozone is formed high up in the atmosphere by the action of ultraviolet radiation on oxygen gas.

This ozone layer is very important for the existence of life on earth because it absorbs most of the harmful ultraviolet radiations coming from the sun and prevents them from reaching the earth. Ultraviolet rays can cause skin cancer. They also damage the eyes.

Ultravioletrays damage immune system by lowering the body’s resistance to disease. It has now been found that the amount of ozone is getting depleted (or reduced) due to the use of chemicals are called chlorofluorocarbons (CFC). CFC are widely used in refrigeration, in fire extinguishers and in aerosol sprayers.
