When visiting two or three "tiger" parks in India, there is CONSTANTLY local people intruding into the consveration area. Cutting reeds, grass, grazing, collecting firework etc etc.

All this has a big effect on the wildlife and the forests and environment.

Just simply WAY TOO MANY PEOPLE. And no serious attempts to reduce population increases let alone reduce the population to sustainable levels.

Unless a gov't had strong policies and actions to conserve wildlife, and the willingness and resources to enforce controls, especially population encroachment into wildlife areas, the wildlife is ultimiately doomed.
