Due to logging and trafficking, almost half of the world’s primates are at risk of extinction, according to the International Union for the Conservation of Nature.

From the Guardian:

The two biggest threats faced by primates are habitat destruction through logging and hunting for bushmeat and the illegal wildlife trade.

“We’ve raised concerns for years about primates being in peril, but now we have solid data to show the situation is far more severe than we imagined,” said Dr Russell Mittermeier, the chairman of the IUCN Species Survival Commission’s primate specialist group and the president of Conservation International.

“Tropical forest destruction has always been the main cause, but now it appears that hunting is just as serious a threat in some areas, even where the habitat is still quite intact. In many places, primates are quite literally being eaten to extinction.”

The picture in south-east Asia is particularly bleak, where 71% of all Asia primates are now listed as threatened, and in Vietnam and Cambodia, 90% are considered at risk. Populations of gibbons, leaf monkeys and langurs have dropped due to rapid habitat loss and hunting to satisfy the Chinese medicine and pet trade.
