Fisherman Lucimar Souza reacts as he talks about the Rio Doce (Doce River) in Linhares, where, according to Brazil's environmental regulator IBAMA, is about to be flooded with mud after a dam, owned by Vale SA and BHP Billiton Ltd burst, Brazil, November 19, 2015. The collapse of two dams at a Brazilian mine has cut off drinking water for quarter of a million people and saturated waterways downstream with dense orange sediment that could wreck the ecosystem for years to come. Nine people were killed, 19 are still listed as missing and 500 people were displaced from their homes when the dams burst at an iron ore mine in southeastern Brazil on Nov. 5. Scientists say the sediment, which may contain chemicals used by the mine to reduce iron ore impurities, could alter the course of streams as they harden, reduce oxygen levels in the water and diminish the fertility of riverbanks and farmland where floodwater passed. According to the predictions of Brazil's environmental regulator IBAMA, the mud will touch the sea, in Espirito Santo state coast, on this Friday. REUTERS/Ricardo Moraes
