Ozone depletion-What does it do?

Changes in the ozone layer have serious impli-

cations for mankind.

Effects on human health:

 Sunburn, cataract,

aging of the skin and skin cancer are caused by

increased ultra-violet radiation. It weakens the

immune system by suppressing the resistance

of the whole body to certain infections like

measles, chicken pox and other viral diseases

that elicit rash and parasitic diseases such as

malaria introduced through the skin.

Food production:

 Ultra violet radiation affects

the ability of plants to capture light energy dur-

ing the process of photosynthesis. This reduces

the nutrient content and the growth of plants.

This is seen especially in legumes and cabbage.

Plant and animal planktons are damaged by ul-

tra-violet radiation. In zooplanktons (microscopic

animals) the breeding period is shortened by

changes in radiation. As planktons form the basis

of the marine food chain a change in their num-

ber and species composition influences fish and

shell fish production.
