Aside from killing hundreds of thousands of people and displacing millions more, the ongoing conflict in Sudan’s Darfur region is also taking a toll on the environment. Displaced people have cut down huge swaths of forest to make mud bricks in wood-fired kilns and to use as cooking fuel. Farmers expelled from their land have been driven to sell timber. “We need to plant millions of trees and introduce new technologies for construction and energy as quickly as humanly possible,” said Clive Bates of the United Nations Environment Program.
