Brazil's controversial plan to build the third-largest dam in the world right in Amazon rainforest got the go-ahead from the environmental ministry this week. The ministers approved the permits for the dam project, and now companies can begin to bid on the building rights. But whoever wins will have to pay out at least some money to protect the local environment.

Xingu River, has the additional trouble of being in one of the most important habitats in world and near to populations of indigenous peoples. The Xingu is a tributary of the Amazon River. In the announcement yesterday, environment minister Carlos Minc tried to reassure everyone that Belo Monte would not be an ecological disaster.

. But Brazilian officials say that about 12,000 people living in towns beyond the protected wild areas will be affected by the construction, and may have to be relocated. Whatever company wins the bid to build the dam will have to pay in excess of $800 million to protect the environment and offset damage caused by the dam, and to resettle the displaced. But Minc's assurances didn't satisfy all the project's critics, who

. They also contend that his pledge not to displace native populations is untrue, because the dam could flood nearly 200 square miles and affect 40,000 people there. When completed, the dam could power the homes of 23 million people, the BBC reports. And with Brazil's population growing steadily, Belo Monte won't be the last dam project in the Amazon: 70 more are in the planning stages.
