India has significant biological diversity but is experiencing threats to its forest and wildlife. 20% of mammal species are threatened and some like the pink-headed duck are endangered or extinct. Habitat destruction, hunting, poaching, overexploitation, and environmental pollution are responsible for the decline. The Wildlife Protection Act of 1972 and projects like Project Tiger were implemented to promote conservation, but continued threats remain from development, shifting cultivation, mining, and grazing. Local communities have helped resist threats and promote conservation in some areas.
