Life is not possible on the earth without forests. Trees give us oxygen to breathe in. No living being can exist on earth without oxygen.
It there were no forest,the whole earth would be polluted. Industries get many useful things from the forests.The destruction of forests makes their supply impossible.
Carbon dioxide destroys the whole environment. When rain falls on naked hills and plains the fast flowing rain water coming down the hills erodes the fertile soil. This soil flows through streams and rivers and gets deposited in dams and lakes.
They become shallow and their capacity to store water is reduced. The fast flowing rainwater cannot be absorbed by earth with no forest on it and the result is drought and flood. Wild life and eco-system is totally damaged by deforestation.
