In Assam, an exploding population has converted nearly every scrap of land around Kaziranga National Park into a patchwork of villages, crop fields and tea plantations. As animals wander outside the invisible boundaries of the park, there is ever-increasing human-wildlife conflict, with growing injury and casualties on both sides. Tigers kill livestock; elephants and rhinos trample and devour crops, and elephants sometimes trample houses. All three of these species sometimes attack people. People shoot and poison animals that stray into their communities.
