Orangutans are the world's largest tree-climbing mammals and are closely related to humans. They are extremely patient and intelligent, as well as very observant and inquisitive. They are divided into two species, the Sumatran species and the Bornean species, which are both classified as Critically Endangered. Their rainforest habitats are disappearing at an alarming rate because of deforestation and clearing of the land for pulp paper and palm oil plantations. The remaining forest is degraded by drought and forest fires. Poaching orangutan infants and hunting for meat also threatens the species. All of this makes their extinction in the wild likely in the next 10 years.
