Critical orangutan habitat is rapidly being lost through illegal and legal logging in Sumatra. Their habitat has decreased over 80% in the last 20 years. Hunting orangutans for meat and killing adult females to obtain infants for the illegal pet trade has also caused an estimated decline in the orangutan population of 30 to 50% in the last 10 years. Uncontrolled forest fires have also harmed orangutan habitat.
