Rocinha favela, Rio de Janeiro, Brazil from Most Densely Populated Places on Earth

These are the largest favelas (slums) in Brazil, located in Rio de Janeiro. Rio is not actually one of the most densely populated cities in the world, but Rosinha is literally similar to the entire independent world. But if you want to see the real Rocinha, you must hurry, because after the World Cup-2014 it will really quickly become a "civilized" place.
