Why is damage to the ozone layer a cause for concern? What steps are being taken to limit this damage?


The ozone shields the surface of the earth from ultraviolet (UV) radiation from the sun. These radiations are highly damaging as they can cause cancer in both plants and animals, damage to eyes and immune system. They can also lead to variations in global rainfall, ecological disturbances and dwindling of global food supplies.

Due to these reasons, damage to the ozone layer is a major cause for concern. Steps which are taken to limit this damage:

(i)To decrease the use of synthetic chemicals like chloro fluorocarbons (CFCs) which are used as refrigerants and in fire extinguishers.

(ii) In 1987, the United Nations Environment Programme (UNEP) succeeded in reaching an agreement to freeze CFC production at 1986 levels.
