Question

Why is the depletion of the ozone layer a matter of concern for us? What steps have been taken to minimise it?

Answer 1

There is an increased concern about the effects of ozone depletion. The depletion of ozone causes the harmful UV rays to reach the earth and this has resulted in an increased incidence of skin cancers in humans. UV rays may also cause genetic mutations in living organisms.

To minimize this, the release of CFCs into the atmosphere must be reduced. CFCs used as refrigerants and in fire extinguishers should be replaced with environmentally safe alternatives. Also, the release of CFCs through industrial activities should be controlled.
