Vultures gather to eat waste in Bica beach, on the banks of the Guanabara Bay, with the Sugar Loaf mountain in background, 500 days ahead the Rio 2016 Olympic Games in Rio de Janeiro March 24, 2015. As part of its Olympic bid, Rio promised to clean up 80 percent of the bay for the games. But local government officials have already admitted that a cleanup by 2016 is not achievable. Despite millions of dollars of investment over the years, the bay still stinks of sewage. Sailors who visited the city for test events complained of a floating sofa and a dead dog in the water.

People enjoy carnival while shouting slogans of female empowerment and anti harrassment in Sao Paulo, Brazil on January 28, 2018. The carnival is marked by a lot of fun, but also has space to talk about more serious things – without losing the good mood. Parading for the first time in São Paulo, the Vaca Profana block proposed a reflection on sieges and machismo. (Photo by Cris Faga/Rex Features/Shutterstock)
