BUKIT LAWANG, INDONESIA - JUNE 12: Two orangutans play with park ranger boatmen on the Bohorok River next to a rainforest June 12, 2009 in Bukit Lawang, Sumatra, Indonesia. Bukit Lawang offers the public a rare glimpse of the endangered orangutans on the edge of the Gunung Leuser National Park. The orang-hutan, which is a Malay word for "person of the forest," often live up to 30-40 years in the wild. Bukit Lawang's orangutan center was set up in 1973 to help primates readjust to the wild after captivity or displacement through logging, land clearing or illegal capture. There are an estimated 6,600 orangutans living in pockets of Indonesia's Sumatra and Aceh provinces. (Photo by Robert Nickelsberg/Getty Images)
