What is Ozone layer? How is it depleted and what are the control measures?

Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.

Some species of plants and animals have been threatened, rare, endangered or critically endangered due to such practices. Several valuable species of plants and animals have become extinct due to these activities.
