Orangutans and Global Warming

Not only are they threatened to become extinct due to humans taking their homes and illegal killing but they are also in trouble due to global warming.
The future for orangutans is certainly one that is in trouble. In the past decade the number of them in the wild has dropped by 50%.
Both species of orangutans are in danger of becoming extinct which is why you will find so many conservation efforts in place to help them.
