Indonesia is home to the world's third largest tropical forest, but it's disappearing quickly. Though often illegal, the forests are cut down both for a booming pulp and paper industry as well as to clear land for oil palm plantations, which supply diverse industries from biofuel to soap to cosmetics.

Because of deforestation, Indonesia is also the world's third largest greenhouse gas contributor, behind only the U.S. and China; after the forest is cut down, the carbon normally sequestered in the peatland soil is no longer shielded from being released into the atmosphere.
