BATUMBELIN, INDONESIA - JUNE 11: A young orangutan sits in a large cage at the Sumatran Orangutan Conservation Center June 11, 2009 in Batumbelin, Indonesia . The center, run by PanEco, a Swiss-based NGO, takes in orphaned or rescued infant orangutans and trains them to be released into the wild, sometimes over a period of 1-3 years. Young orangutans normally spend up to 8 years with their mothers learning how to climb and feed themselves. The quarantine center was started in 2001 and has released 120 orangutans since 2003.
