People navigate on their boats as they protest against the pollution of Guanabara Bay and the government politics on its remediation in Rio de Janeiro, Brazil, August 8, 2015. Rio de Janeiro continues to face criticism locally and abroad that the bodies of water it plans to use for competition in the 2016 Olympic Games are too polluted to host events. Untreated sewage and trash frequently find their way into the Atlantic waters of Copacabana Beach and Guanabara Bay – both future sites to events such as marathon swimming, sailing and triathlon events.
