The Amazon in particular has been a major concern for environmentalists. Currently, around 85 percent of the world´s supply of palm oil is produced in Malaysia and Indonesia alone. But as demand rises and plantation land becomes less available in these areas, producers are increasingly looking elsewhere to expand cultivation. The Amazon and other tropical areas around the equator are hot spots for future plantations since oil palm trees need temperatures between 25 and 28 degrees Celsius, regular rainfall and strong sunlight to thrive.
