The use of palm oil in food products has attracted the concern of environmental groups; the high oil yield of the trees has encouraged wider cultivation, leading to the clearing of forests in parts of Indonesia to make space for oil-palm monoculture. This has resulted in significant acreage losses of the natural habitat of the three surviving species of orangutan. One species in particular, the Sumatran orangutan, has been listed as critically endangered.
