RIO DE JANEIRO, BRAZIL - MARCH 18:  A young resident stands next to a children's kitchen playset in an impoverished area in the unpacified Complexo da Mare slum complex, one of the largest favela complexes in Rio, on March 18, 2014 in Rio de Janeiro, Brazil. The group of 16 communities house around 130,000 residents while plagued by violence and poverty and dominated by drug gangs. Mare is located close to Rio's international airport and has been mentioned as a likely pacification target for the police. Rio's Police Pacification Unit (UPP) now controls 38 of the city favelas amid the city's efforts to improve security ahead of the 2014 FIFA World Cup and 2016 Olympic Games.
