SAO LUIZ DO TAPAJOS, BRAZIL - NOVEMBER 26:  A boat travels along the Tapajos River during the 'Caravan of Resistance' protests staged by indigenous groups and supporters in opposition to plans to construct a hydroelectric dam on the Tapajos River in the Amazon rainforest on November 26, 2014 in Sao Luiz do Tapajos, Para State, Brazil. Indigenous groups and activists travelled by boat from communities along the river to the town to express resistance to the proposed 8.040- MW Sao Luiz do Tapajos mega-dam which is one of a series of five dams planned in the region that will flood indigenous lands and national parks. The United Nations climate conference is scheduled to begin December 1 in neighboring Peru.  (Photo by Mario Tama/Getty Images)
