(a) If we go on cutting trees then:

* If we go on cutting trees, the chances of soil erosion will increase. As a result, soil losses humus and become less fertile.

* The natural habitat of many animals get completely destroyed.

* The ecological balance will get disturbed and floods and drought will become more frequent.

(b) The habitat of an animal is disturbed:

The habitat of an animal provides it with necessities such as shelter, food, and protection. If the habitat of an animal is disturbed, then it will be forced to go to other places in search of food and shelter. The animal could get killed by other animals in this process.

(c) If the top layer of soil is exposed:

If the top layer of soil is exposed, then it will gradually expose the lower layer of soil, which is hard and rocky in nature. This soil has less humus and is less fertile. Gradually soil erosion will make the land barren or infertile.
