Asian elephants used to live in the forests from Iraq to Southern China. Since these forests were cut down to make room for farms and villages, the elephants had to live in small, hilly regions. These small areas cannot supply enough food for them. An adult elephant eats about 331 pounds (150kg) of grasses, leaves and other plants each day. When forests were larger, Asian elephants migrated with the seasons. In this way, they found new food supplies. The plants and trees could also grow again after elephants left.

Today, there is nowhere for the elephants to go. Experts say that the Asian elephant population is about 55,000 living on a habitat of about 19,000 square miles (30,400 km2). In contrast to this, the African elephant population is about 10 times this size and lives on almost 3 million square miles (4.8 million km2) of available habitat.
