Residents from the nearby Providencia ‘favela’ community swim and cool off in the polluted Guanabara Bay in the historic port district in Rio de Janeiro, Brazil.

Ahead of the games, the port district is undergoing a controversial multibillion dollar urban renewal program although some projects have been delayed in the midst of Brazil’s recession.
