The picture-perfect scenario by the entrance of Rio de Janeiro has suffered with the contamination of the city's sewers for many years, and is today a dangerous and polluting industrial park. Transformed into the backyard of the oil industry, the Guanabara Bay is today an area in dispute. On one side, there are the scientists, the fishermen and the activists. On the other side, there are the gigantic oil companies and the neglect with the area's basic sanitation. The Soccer World Cup and the Olympic Games have come and gone, and the waters at the Guanabara Bay are still polluted and agitated.
