A loggerhead sea turtle (Caretta caretta) crawls to the sea after laying her eggs on the beach, about 4 kilometers of the mouth of Rio Doce in Regencia village, where, according to Brazil's environmental regulator IBAMA, the river is about to be flooded with mud after a dam, owned by Vale SA and BHP Billiton Ltd burst, in Brazil November 20, 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 southeasternBrazil on November 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 IBAMA's forecast, the sediment will reach the sea in Espirito Santo state coast this weekend. REUTERS/Ricardo Moraes
