Rainforests are often illegally set on fire and left to burn for sometimes weeks on end to make way for new palm oil plantations.
Habitat has been severely hindered, and orangutans are often killed in these wildfires or its toxic haze. This has also created food scarcity, and as a result, orangutans are often found on palm oil plantations looking for food, and shot by plantation workers who view them as pests.
From 1999 to 2015, It's estimated that 150,000 orangutans were killed as a result of palm oil expansion, bringing today's population to around 60,000.
