RIO DE JANEIRO, BRAZIL - NOVEMBER 02: A girl poses while playing football in the Chacara do Ceu favela, or shantytown, on November 2, 2013 in Rio de Janeiro, Brazil.  The favela was previously controlled by drug traffickers and is now occupied by the city's Police Pacification Unit (UPP). Football is a very popular pastime played throughout the shantytowns of Rio and all over Brazil.  The UPP are patrolling Rio's favelas amid the city's efforts to improve security ahead of the 2014 FIFA World Cup and 2016 Olympic Games.  (Photo by Buda Mendes/Getty Images)
