The atmosphere has an ozone layer which protects the earth's surface from excessive ultraviolet rays from the sun.
-Chlorine from chemicals such as Chlorofluorocarbons that were used for refrigeration,air conditioner,fire extinguishers and aerosols cause damage to the ozone layer.
-This is where chlorine from chlorofluorocarbons reacts with ozone dissociating it into oxygen.
-This reduces the amount of ozone layer thus allowing entry of U.V rays entering the earth's surface.
-As a result ozone depletion occurs.
OZONE DEPLETION EFFECTS.
-More cases of skin cancer
-Increase in eye cataract
-Severe sunburns
-Suppression of immune system
- Acid deposition would increase in areas were SO2&NOx are produced
-Deterioration of paints, plastics, rubber etc.
- Deterioration to biological food chain
-Increase in photo chemical smog
