Why is depletion of ozone layer a cause of concern?

1.	Why is depletion of ozone layer a cause of concern?
Answer» • Ozone layer is a high concentration of ozone molecules present in the stratosphere. • The main function of the ozone layer is to absorb the Sun’s ultraviolet radiation, hence protecting the Earth from its harmful effects. • Depletion of the ozone layer is a cause due to excessive use of CFCs or ammonia. • Damage of ozone layer is cause of concern because ultra violet radiation from the sun will reach the earth and will effect human beings, plants and animals. • After the Montreal Protocol, the Ozone layer is improving by the control use of CFCs and other harmful chemicals.
