How to Clean Up an Oil Spill
Oil is the most common pollutant in the oceans. More than 3 million metric tons of oil contaminates the sea every year. The majority of oil pollution in the oceans comes from land. Runoff and waste from cities, industry, and rivers carries oil into the ocean. Ships cause about a third of the oil pollution in the oceans when they wash out their tanks or dump their bilge water. Oil spills account for less than 15% of the total oil in the oceans but are probably the most obvious form of oil pollution. The damage caused by oil spills is certainly seen right away.
