The ozone that is present in the upper layer of the atmosphere is known as the "ozone layer". This layer protects life on earth by absorbing most of the ultraviolet radiation that is emitted by the sun. Exposure to too much of ultraviolet radiation may lead to skin cancer,cataracts,suppression of the immune system. It is also believed to reduce the productivity of certain crops. Atmospheric ozone is known as "good ozone". When man-made chlorofluorocarbons reach the ozone layer,they are broken apart by short-wave energy from the sun. The free chlorine atoms then break apart the molecules of ozone, thus creating holes in the ozone layer.
