Sailing events at the 2016 Summer Olympics will be held on Rio de Janeiro's Guanabara Bay, but dire warnings have been issued about the bay's filthy, squalid condition and the near impossibility of a timely cleanup. In May, a New York Times reporter cited car tires, mattresses, dog carcasses, a partly submerged sofa and free-flowing untreated raw sewage. A Brazilian competitive sailor admitted he'd seen four human corpses in the bay. By comparison, for the Beijing Olympics, 1,000 cleanup boats were launched just to remove algae from the sailing venue. Only three cleanup boats are on Guanabara now.
