Answer 2

Ozone layer is a protective layer of ozone (O3) present in the lower stratospheric region in atmosphere. It protects our environment by absorbing the harmful UV radiation present in the sun light. It is depleted by human activities that involve the use of gases like chlorofluorocarbons (CFCs) and bromoflurocarbon which are present in refrigerators, air-conditions. As a result of ozone layer depletion a small hole is formed near north poles which iscalled as ozone hole. Harmful UV radiations are entering through this hole anddamaging human life by inducing cancer and several other hazardous diseases.
