Palm oil plantations can be found all over the world. With my palm oil knowledge, most palm oil plantations can be found on the Indonesian islands of Sumatra and Borneo. Part of Malaysia is on Borneo, too. So part of the plantations are in the Malaysian part of Borneo. Some palm oil plantations are in western and central Africa. According to Rainforest Rescue, Peruvian native tribes are trying to get the palm oil industry out of the Peruvian Amazon.
