Rainforests, or rain forests, are being destroyed because of logging and slash-and-burn agriculture. Rain forest woods are highly prized, and although protests have slowed down logging in the Amazon, a lot of logging continues. Slash-and-burn agriculture is the cutting and burning of forests for agricultural purposes. The land is temporarily fertilized by the ashes of burnt trees and brush, but this fertility does not last long. New patches of rain forest need to be cut down each year to provide new farmland. New incentives in areas like the Amazon are encouraging sustainable logging and agricultural practices.
