Felix Finkbeiner is a young man in a hurry to get the world to plant trees. The Trillion Tree campaign aims to get the world to plant 1 trillion trees in the next 30 years. To put that into context, scientists calculate there are currently 3 trillion trees growing worldwide. Extensive tree plantations “would require a major fraction of the global land surface with intolerably large environmental and social costs,” Boysen says. “We need to plant at least a trillion trees to get 600 billion, since many will not survive,” he says.
