INNER MONGOLIA, CHINA – AUGUST 22: Badamusileng, a Mongolian nomadic herder, poses for a photograph on August 22, 2007, in his tent, or yurt, west of Mandubaolage. Much of the once-green pastures of Inner Mongolia have turned into dust bowls because of drought and climate change, as well as overgrazing. (Photo by Palani Mohan/Getty Images)
