Orang-utans live in the peat rainforests of Malaysia and Indonesia. It can be tough terrain to travel through on foot so studying and surveying wild orang-utans is difficult and dangerous.

This week Shared Planet explores the potential of drones to help us share the planet with orang-utans - but also explores the possible pitfalls of using this controversial technology.
