Question

What will happen if,
(a)We go on cutting trees.
(b)The habitat of an animal is disturbed
(c)Top layer of soil is exposed

Answer 1

Hint: Sometimes when the topmost layer of the soil gets removed it is known as soil erosion. When habitat of animals gets disturbed it leads to disturbance in flora and fauna. When we cut trees, this can unbalance gases present in the environment.

Complete answer:
(a) Large scale tree cutting can lead to deforestation. Plants create oxygen and absorb greenhouse gases. The destruction of trees leads to global warming. Cutting trees can change the temperature which is not helpful for survival of organisms.
Cutting of trees can result in loss of habitat for animal species. Loss of forests result in warmer and drier climates near the tropics which could destroy the ecosystem.
Earth will lose its top fertile soil layer and get converted into desert as trees bind the soil.

(b)
(1) The habitat of an animal provides it with necessities such as shelter, food and protection.
(2) If the habitat of an animal is disturbed, some species will get affected which will result in the disturbance of the food chain.
(3) If the habitat is disturbed, animals will be forced to go to other places in search of food and shelter and hence could be killed by other animals.

(c)
(1) If trees are cut down it will automatically result in soil erosion i.e the removal of the topmost layer of the earth.
(2) Top layer of the soil is highly fertile, its removal will result in exposure of the lower layer which is hard and rocky which contains less humus.
(3) If the top layer is removed there will be no production of crops for increasing population which can result in starvation.
(4) Continued soil erosion will make the land barren or infertile.

Note: Environment provides various resources for making our lives easier but these resources should not be destroyed as their destruction can lead to natural disasters which affect the lives of organisms. Natural resources should be preserved, not future generations. The policy of three R’s should be followed that is reduce, reuse and recycle.
