Q. What is the main cause for the extinction of some species in tropical forest?

A) Deforestation
B) Afforestation
C) Pollution
D) Soil erosion
Explanation

Deforestation is the depletion of forest resources. Its main cause is the explosion of human and livestock population with the increased demand of the basic needs. Ideally, one third (33%) of land of a country must be covered by forest. In India, forest cover is only 19.43% out of which only 13% are thick forests. India is losing about 1.5 million hectare of forest covers each year. The major effect of deforestation is the loss of precious wild life, rare species of flora and fauna. Directly or indirectly, deforestation caused intensified soil erosion, accentuated flood, drought and the worst pollution.
