Answer.

Forest refers to an extensive area of land which is mostly covered by trees of different sizes and species. Over exploitation of forest resources can cause the following environmental problems;

(i) Increase in soil erosion; As the rain drops /falls harshly in the exposed soil and remove the fertile soil.

(ii) Excessive evaporation; This causes drought (problems of water because streams and springs dry up).

(iii) Accelerated desertification. This caused by prolonged drought of an area since the absence of forest affect rain formation.

(iv) Pollution of the atmosphere which can lead to greenhouse effect and global warming i.e. when forests are cleared by burning adding carbon dioxide in the atmosphere.

(v) Disappearance of some species of trees (loss of biodiversity).

(vi) Unreliable rainfall due to the excessive evaporation.
