Small boats sit on the shore of Guanabara Bay in the suburb of Sao Goncalo, across the bay from Rio de Janeiro, Brazil, Tuesday, Nov. 19, 2013. The bay was home to a thriving artisanal fishing industry and popular palm-lined beaches as recently as the late-1970s, but has become a watery dump for waste from shipyards and two commercial ports. Rio de Janeiro will host the 2016 Olympic Games.
