Dramatic decline of Bornean orangutans

Global demand for natural resources has reduced the number of orangutans by more than 100,000 animals in the last 16 years

Nearly 50 years of conservation efforts have been unable to prevent orangutan numbers on Borneo from plummeting. The latest data published by a team from 38 international institutions, led by researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, the German Centre for Integrative Biodiversity Research (iDiv) and Liverpool John Moores University in Great Britain, suggests that between 1999 and 2015 the total number of Bornean orangutans was reduced by more than 100,000 animals.
