November 26, 2014. A member of the Munduruku indigenous tribe carries rocks on a sandbar on the Tapajos River in protest against plans to construct a series of hydroelectric dams in in Para State, Brazil. The tribe members used the rocks to write 'Tapajos Livre' (Free Tapajos) in a large message in the sand in an action in coordination with Greenpeace. After years of fighting, the Munduruku were successful in lobbying the government to offically recognize their traiditonal territory with a demarcation. This recognition forced IBAMA, Brazil's Environmental Agency, to cancel the environmental licensing process for the 12,000 megawatt Tapajós hydroelectric complex, due to the unconstitutional flooding of their now recognized land. But the fight continues as 40 more dams are still planned for the river basin.&nbsp; /Aaron Vincent Elkaim
