It looks like we can say goodbye to several Rio Xingu apisto and Teleocichla species and other fish. The Belo Monte hydroelectric project, canceled in the 1990s, due to its effects on the environment and reservations of native peoples, has approval to be constructed: http://news.bbc.co.uk/2/hi/americas/8492577.stm. It will be the 3rd largest dam in the world, but will not be able to produce electricity for 3 to 5 months during the dry season. This is probably only the start.
