Baby orangutans on the island of Sumatra are being captured and sold as pets, but charities are working to rescue the animals and confront the owners, BBC is reporting as part of a series focusing on the wildlife of Indonesia’s Leuser rainforest and the people trying to save them. Leuser, in Sumatra, is one of the most biodiverse places on earth. It’s also the only place in the world where orangutans, rhinoceroses, elephants and tigers still live together. But the environment is under constant threat from palm oil developers, agriculture and infrastructure projects. Already, more than 110,000 hectares of rainforest has disappeared from the region.
