About half of the orangutans on the island of Borneo were either killed or removed between 1999 and 2015, according to new research.
“That’s a huge amount of loss,” said Professor Serge Wich from Liverpool John Moores University, a co-author of the study published today in the journal Current Biology
“It’s a higher amount than we thought, and that we were thinking based on previous studies,” Professor Wich said.
Maria Voigt from the Max Plank Institute for Evolutionary Anthropology is another co-author of the research, which pooled data from 38 international institutions.
