Ever wondered where all that rain goes after a storm? Most of it is absorbed by soil and plants, while watersheds carry the rest into nearby lakes and rivers.

Saving the rainforest used to be about protesting the number of trees that were cut down. But some researchers propose that reforestation could combat habitat loss and animal extinction. Can we really bring a decimated rainforest back to life?
