Con Sigourney Weaver

Canadian director James Cameron (L) and US actress Sigourney Weaver (R) participate in a protest against a proposed dam that would be the world’s third largest hydroelectric project in the Brazilian Amazon, in Brasilia, Brazil, 12 April 2010. Cameron and Weaver were joined by indigenous people and activists, urging the government to halt the planned Belo Monte project. Brazil’s government says Belo Monte will provide much-needed clean energy for the country, but Indian groups say they will be displaced by the dam. Environmentalists say its benefits won’t make up for the damage to the jungle. (EPA/FERNANDO BIZERRA JR)
