Guanabara Bay is beautiful only from afar. Crusing the bay on a boat you can see all kinds of trash floating on the water. The water might be too polluted to host the sailing and surfing competitions of the 2016 Olympic Games, critics say. Now the state of Rio de Janeiro tries to clean the bay with barriers and boats. But even if the barriers in the rivers and canals keep a lot of trash from entering the bay, too many plastic bags, bottles and other waste products still find their way. To collect these items, the state promised to run ten garbage boats by the end of 2014. So far, only three are operating. Djalma Mathias dos Santos works on one of them, trying to clean the 412 square kilometers of the bay.
