Construction continues at the Belo Monte dam complex in the Amazon basin on June 15, 2012 near Altamira, Brazil. Belo Monte will be the world’s third-largest hydroelectric project and will displace up to 20,000 people while diverting the Xingu River and flooding as much as 230 square miles of rainforest. The controversial project is one of around 60 hydroelectric projects Brazil has planned in the Amazon to generate electricity for its rapidly expanding economy. While environmentalists and indigenous groups oppose the dam, many Brazilians support the project. The Brazilian Amazon, home to 60 percent of the world’s largest forest and 20 percent of the Earth’s oxygen, remains threatened by the rapid development of the country.
