Orang-utan is now rare animals, because human beings constantly destroy their habitat and often also sell their babies for illegally as pets. Estimated orangutan population in the world recently numbered only 100,000 tails. We have been developed to conserve wildlife populations are in Indonesia and Malaysia.

Location and habitat
Orang-utan is found in tropical rain forest areas of Southeast Asia, namely in the island of Borneo and Sumatra in the territory of Indonesia and Malaysia. They usually live in dense trees and make a nest of leaves. Orangutans can live to the variety of forest types, ranging from forest dipterokarpus low hills and plains, watersheds, freshwater swamp forests, peat swamp, dry land in the mangrove swamps and palm, to the mountain forests. In Borneo orangutans can be found at an altitude of 500 m above sea level (asl), while his relatives in Sumatra has been reported to reach the mountain forests at 1000 m above sea level.
Sumatran orangutan (Pongo abelii lesson) is one of the endemic animals that exist only in Sumatra. Orangutans in Sumatra occupies only the northern part of the island, ranging from Timang Gajah, Central Aceh until Selatan.Keberadaan Tapanuli Sitinjak in this mammal Reserved 5 in 1990 on the conservation of Natural Resources and the Ecosystems and classified as 'Critically Endangered' by IUCN. In Sumatra, one of the orangutan population is in the river basin (DAS) Batang Toru, North Sumatra. The population of wild orangutans in Sumatra is estimated to number 7300 [2]. In the Batang Toru watershed with 380 tail pupulasi density of about 0.47 to 0.82 fish per square kilometer. The population of Sumatran orangutans (Pongo abelii lesson) is now estimated at 7500 head. Whereas in the era of the 1990s, an estimated 200,000 fish. Their population is at 13 separate geographical regions. These conditions led to their survival increasingly threatened with extinction. [1] At present almost all sumatera orangutans are found only in the province of North Sumatra and Aceh province, the Lake Toba as the most southern boundary spreading. 2 Only a relatively small population in the southwest of the lake, the East Sarulla and forests in the West Batang Toru. Largest orangutan population in Sumatra, found in the West Leuser (2508 individuals) and East Leuser (1052 individuals), and Swamp Singkil (1500 individuals). Another population estimated potential to survive in the long term (viable) is in Batang Toru, North Sumatra, with a size of about 400 individuals.
Orangutans in Borneo who are classified as 'endangered' by IUCN is divided into three subspecies: Orangutans in Borneo grouped into three types, namely Pongo pygmaeus pygmaeus are located in the northern part of the Kapuas River to the northeast of Sarawak; Pongo pygmaeus wurmbii found ranging from south of the Kapuas River to the west of Barito River; and Pongo pygmaeus morio, estimated the total population in the wild nature 45,000 to 69,000 only. In Borneo, orangutans can be found in Sabah, Sarawak, and almost all the lowland forests of Borneo, except South Kalimantan and Brunei Darussalam.

Included orangutans Although omnivorous animals, most of them only eat plants. Orangutans favorite food is fruit. Other foods a.l.:

Largest predator adult orangutans are humans. Humans (in the form of institution / certain companies) tend intend to chop up / clean out their habitat (tropical rainforests). Some people even buy memperjual them as pets or smuggled to other countries to produce large amounts of money. Things like this makes the population of endangered orangutans.
