What will happen if: [NCERT]1) we go on cutting trees.2) the habitat of an animal is disturbed.3) the top layer of the soil is exposed.

1) If we go on cutting trees, rainfall and fertility of the soil will decrease. The chances of natural calamities such as floods and drought will increase. It will lead to decrease in the water holding capacity of the soil and movement of water from the soil surface into the ground. Animal life is also affected by deforestation. 2) If the habitat of an animal is disturbed, it endangers their existence. Survival of some animals becomes difficult because of the disturbances in their natural habitat. 3) Removal of the top layer of soil exposes the lower hard and rocky layers. This soil has less humus and it is less fertile. Gradually the fertile land can convert into deserts.
