Ozone layer is a layer found in stratosphere that prevents harmful uv rays from reaching humans. However, due to the use of CFCs, there is a hole in the ozone layer above the Antarctica. Hence, more friendly HFCs are used as they are environmetally friendly as they does not contain chlorine atoms.
90% of the ozone layer is found in the stratosphere. Ozone actually protects us humans from the harmful UV radiation. However, in recent years, the ozone layer is depleting and the main cause is probably due to CFCs. Chlorine atoms destroy the ozone layer. If this prolongs, we will be more exposed to the harmful UV radiation which may cause skin cancer. In 1989, countries have step up and banned the production of CFCs to prevent the ozone layer from further depletion.
