Human activities and man's insensitivity to the environment have been the major causes for the depletion of flora and fauna.
Various activities carried out by man are:
1. Deforestation for agricultural expansion
2. Degradation of forests by shifting cultivation
3. Large scale development projects
4. Mining activities
5. Habitat destruction, hunting, poaching, over exploitation of forest products, environmental degradation, forest fires are some other factors which have led to the decline of India's biodiversity.
6. Other important causes of environmental destruction are unequal access, inequitable consumption of resources and differential sharing of responsibility for environmental well-being.
