State reasons for the depletion of Flora and Fauna.

Agricultural Expansion: According to the Forest Survey of India, over 262,000 sq km of forest area was converted into agricultural land in India between 1951 and 1980. Moreover, a substantial part of the tribal belts has been deforested or degraded by shifting cultivation.

Enrichment Plantation: Enrichment plantation was done to promote a few favoured species in many parts of India. This practice involves plantation of a single commercially valuable species. This leads to elimination of other species.

Development Projects: Large scale development projects have also contributed significantly to the loss of forests. Over 5,000 sq km of forest was cleared for river valley projects since 1951.

Mining: Mining has also caused large scale depletion of flora and fauna in many areas. For example; the ongoing dolomite mining is seriously threatening the Buxa Tiger Reserve in West Bengal.

Unequal Access to Resources: Social inequality is another major factor to depletion of flora and fauna. The rich people consume much more than the poor and thus cause a higher degree of environmental damage.

* Forest and wildlife provide directly and indirectly many products like-wood, medicines dyes, food, fuel, fodder manure etc.
*The greatest damage caused was due to expansion of the railways, agriculture, commercial and scientific forestry and mining activities.
