In this May 15, 2014 photo, trash litters a forested area on the shores of Guanabara Bay in Rio de Janeiro, Brazil. The country will not make good on its commitment to clean up Rio de Janeiro's sewage-filled Guanabara Bay by the 2016 Olympic Games. Authorities pledged to cut by 80 percent the flow of pollution into Guanabara Bay by the 2016 Games through the expansion of the sewage network and the construction of River Treatment Units, or RTUs, built at the mouths of rivers flowing into the bay. The facilities would filter out much of the sewage and trash. But little progress has been made on either front. (AP Photo/Felipe Dana)
