Question

what is damage to the ozone layer a cause for concern

Answer 1

Ozone layer protects us from Sun 's harmful UV radiations. It shields the surface of the earth from ultraviolet radiations from the sun .This radiation is highly damaging to organisms, e. g it is known to cause skin cancer in human beings.

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