Wild at Heart: The Plight of Elephants in Thailand

Elephants in Thailand have a big unemployment problem. Long a revered creature in traditional Asian cultures and a critical beast of burden for Asian economies, the captive elephant is becoming obsolete. Its plight has only worsened since 1989, when Thailand banned all logging operations, a major employer of these animals. Luckily, the thousands of captive elephants in Thailand have never been selectively bred and remain genetically wild. Watch how local and international scientists are reintroducing Asian elephants to the forest and reestablishing herd structures in hopes of reverting them to their most noble occupation—living wild.
