Discuss the consequences of Global-warming and ozone-layer depletion.

Explanation

Consequences of global warming:-
1. Deleterious changes in the environment and resulting in odd climatic changes.
Ex. (El Nino effect)
2. Increased melting of polar ice caps as well as other places like Himalayas snow caps.
3. Rise in sea level that can submerge many coastal areas.
4. Increased temperature will lead to increased weed growth, eruption of diseases and pests, thus crop productivity will decrease.
Consequences of ozone-Layerdepletion
1. UV-B Damages DNA and proteins of living organism causing mutation.
2. It causes skin aging, skin cell damage and skin cancers.
3. UV-B is absorbed by human eye and at high dose it causes inflammation of cornea.
This is called snow blindness, cataract.
4. The depletion of ozone layer allows uv radiations to reach the earth surface.
