A volunteer carries a box of fishes rescued from the waters of 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 

People use snowshoes during a tour of the Great Kemeri Bog, Latvia, October 17, 2015. The Kemeri bog is more than 8,000 years old and is one of the largest dry moss swamps in the Baltics. A more than decade-long joint restoration of the bog by the European Union and the Latvian government helped the bog recover its intact high moss marshes, damp black alder forests, floodplain meadows and seaside lakes - features now considered rare in Europe due to industrialisation.

A dead tree is seen in a marsh wetland area near Lafitte, south of New Orleans, Louisiana, United States August 16, 2015. In 2005, Hurricane Katrina triggered floods that inundated New Orleans and killed more than 1,500 people as storm waters overwhelmed levees and broke through floodwalls. Congress authorized spending more than $14 billion to beef up the city's flood protection after Katrina and built a series of new barriers that include manmade islands and new wetlands. Reuters photographer Carlos Barria returned to New Orleans after documenting events in 2005 and found a city much rebuilt and renovated, although abandoned homes show Katrina’s lingering impact.
