Orangutans live in the forests of Sumatra and Borneo. They spend their entire lives in trees. They sleep in nests that they build in these trees. A majority of the orangutans' diet consists of fruit (about 60%), and the rest of what they eat is simply leaves and shoots found in trees. There is normally water in the fruit and tree holes, which is what they drink.
The Human Effect on Orangutans
There are two different species of orangutan: Bornean and Sumatran. The Bornean orangutan has approximately 41,000 left in the wild, but the Sumatran orangutan is critically endangered, and only has an estimated population of 7,500. Keep in mind that a century ago, there were more than 230,00 orangutans. They are endangered because of the the deforestation and devastation in the wild, mainly for agricultual reasons. Another tragedy occuring is caused by illegal pet trade, which essentially means that young are being taken from their mothers, who are killed by poachers if they try to protect their young.
