The continuing devastation of the world’s tropical rain forest affects us all—spurring climate change, decimating biodiversity, and wrecking our environment’s resiliency. Millions of worried people around the world want to do whatever it takes to save the forest that is left. But halting rain forest destruction means understanding what is driving it.
