CHIANG MAI, Thailand - FEB 27 2006: A volunteer helps feed fresh fruits and vegetables to an elephant at the Elephant Nature Park. In the wild, elephants can eat between 250 - 525 pounds of food a day. Environmental tourism in the biggest tool being used to make sustainable models for elephants to thrive, both physically and economically. Asian elephants - strong, social, and intelligent - have been trained for thousands of years for use in transportation, labor, and ritual. In Thailand, Elephants are of immense cultural importance, but their numbers are shockingly plummeting. In 1905, there were over 100,000 elephants in this land - now they are estimated at less than 5,000, of which barely half are in the wild. (Photo by Logan Mock-Bunting)
