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 forest. 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.
Afforestation or reforestation is the only major way to conserve the natural resources and the previous rare species.
