Explain in short : Effect of ozone depletion on environment.

With the depletion of ozone layer, more $UV$ radiation filters into troposphere. $UV$ radiations

lead to ageing of skin, cataract, sunburn, skin cancer, killing of many phytoplanktons, damage to fish productivity etc.

Plant proteins get easily affected by $UV$ radiations which leads to the harmful mutation of cells. It also increases evaporation of surface water through the stomata of the leaves and decreases the moisture content of the soil.

Increase in $UV$ radiations damage paints and fibres, causing them to fade faster.
