_______________________________
At an attitude of 25-30 km , earth have a layer in which conc. of ozone is about 10ppm . It is called Ozone layer.
_______________________________
Due to depletion of ozone ( especially by CFC ) , it was found in early 1980s that a large ozone hole had been created in ozone layer . a similar hole wad found in Northern Hemisphere .
_______________________________
The two ozone - depleting agent are
1) NO produced at the ground level due to human activity or natural sources or is produced in large amounts in the exhaust gases by the engine of supersonic transport planes .
2) compound containing Cl, Fl and C .
commonly known as freons.
introduced in air by aerosol sprays and refrigerating equipments .

The depletion of ozone layer is also known as ozone hole. There is a layer of ozone gas ( O3 ) in the upper atmosphere. 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 which can otherwise cause skin cancer.
It has now been that amount of ozone is getting depleted ( or reduced ) due to which the ozone layer is becoming thinner and thinner day by day, The depletion of ozone layer is due to the use of certain chemicals
A " hole " in the ozone layer above Antarctica has been discovered by the scientists . This hole has occurred due to the increased level of chlorofluorocarbons in the atmosphere. There will be a greater risk if the size of this " hole " increases further. scientists worried that if ozone layer in the atmosphere disappears completely. Then, the harmful ultra- violet radiations would reach the earth and would cause skin cancer and also damage the plants.
