Q. Which of the following are the causes for deforestation? I. Human settlements II. Forest fires III. Hydroelectric projects IV. Overgrazing by livestock V. Demand of wood Which of the statements given above are correct?

A) I, II and III
B) III, IV and V
C) II, III, IV and V
D) I, II, III, IV and V
Explanation

Forest wealth suffers loss in many ways (i) Forest Fires Fire is the worst enemy of forests (ii) Hydroelectic Projects Dams, barriers constructed across the streams to form water reservoirs for generating power or preventing floods submerge and kill large tracts of forests (iii) Grazing by Livestock The animals first eat young plants, then destroy the leaves on the lower branches of tall trees and finally damage their trunks and roots (iv) Population Man has cleared large areas of forests to reclaim land for agriculture, housing, factories and roads. Increased demand for timber, fuel wood, wooden crates and paper has also contributed to the large scale felling of trees
