Actor and Activist, Leonardo DiCaprio, recently posted this photo to his Instagram account with the description: "As the forest of the #Indonesian #LeuserEcosystem continues to be cleared to meet demand for Palm Oil, the critically endangered Sumatran #orangutan is being pushed to the brink of extinction. Here, at the Sumatran Orangutan Conservation Programme's Orangutan Quarantine Center, rescued orangutans are rehabilitated so they can be released back into the wild. If we don't stop this rampant destruction, the Leuser Ecosystem and the Sumatran orangutans that call it home could be lost forever. Click the link in the bio to support this important work. #Indonesia". This is clearly a cause close to his heart. If you'd like to learn more, the link he's talking about can be found here.
