The oceans have become a dumping ground. Mercury emitted by land-based industrial plants finds its way back into our seafood with potentially serious consequences for fish and human health. Meanwhile, tons of concentrated fish waste from offshore fish farming despoils seafloor habitat by snuffing out oxygen and life. Oil spills, for which there is no reliable cleaning mechanism, continue to occur, and the global shipping fleet emits tons of carbon into the atmosphere with no regulations. Oceana is working to stop ocean pollution from all of these sources.
