According to this article almost half of all primates face extinction. There are 634 primate species but 48% of these are on the red list of animals under threat. The main problems facing primates is the destruction of tropical forests and the illegal hunting trade. A recent report has highlighted the 25 most endangered primate species some of which are thought to be down to just a few dozen individuals. Among these are golden headed langur of which there are between 60 and 70 individuals left and the eastern black crested gibbons of which there are around 110. It is hoped that the report will go some way to highlighting the problems facing these creatures before it is becomes too late to save them.
