Our dependence on oil-based technology leads to oil pollution of water, especially the sea. Oil spills such as the blowout in 1969 at Santa Barbara when 10,000 tons of oil entered the ocean are serious enough but they represent the source for less than 10% of the total oil that enters the marine environment annually. Waste oil and grease from industries contribute significantly to marine pollution. Oil films in the sea retard its intake of oxygen and animal life is affected. Water birds are damaged when they are smeared by oil. Fish and lobsters that live in the bottom are killed and washed ashore. To prevent oil spill in harbours, floating booms are used. Another method of combating this pollution is the use of water bubble barriers. Certain chemicals are also used to gel or solidify oil. Then there are mechanical methods of clean-up.
