Orangutans are being forced out of their natural habitat in Indonesian Borneo to make way for farming palm oil, a BBC investigation has found.
Palm oil is a cheap vegetable oil. It's in loads of foods but it's hardly ever written on packet labels.
The orangutan population in the area has halved because they've been pushed out to make room for palm oil farms.
The investigation claims the Indonesian government admits 50,000 orangutans have died because of de-forestation.
