Auckland Zoo's primate keeper Amy takes us into Sumatra's Leuser Ecosystem - home of some of the world's most incredible species. We meet Jack and Agus from the Sumatran Ranger Programme that work in the Leuser 'buffer zone'.
Amy takes us to the site of Sumatra's first orangutan rehab centre in Bukit Lawang. We learn more about orangutans from Amy, including what makes them so special.
With the help of Greenpeace's 'rang tang' video, we discuss why Auckland Zoo supports sustainable palm oil. Nayla shows us around the Orangutan Information Centre and the work they're doing to replant native forests.
We meet Leuser - a blind orangutan that was rescued by SOCP. Amy introduces us to Ian Singleton, director of the Sumatran Orangutan Conservation Programme.
