A bird flies next to garbage in the Guanabara Bay in Rio de Janeiro

A bird flies next to garbage in the Guanabara Bay in Rio de Janeiro March 12, 2014. According to the local media, the city of 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.
