Palm oil is used in a huge range of consumer products, from food and fuel to beauty products and cleaning agents, meaning that demand for palm oil has risen fast. According to the Union of Concerned Scientists (UCS), growing demand is driving increases in deforestation, which accounts for 10 percent of the emissions that cause global warming. Clearing forest for plantations also destroys trees that are home to endangered species and a resource for forest communities, the U.S.-based UCS said.
