"A recent report from National Academy of Sciences says that most of the oil pollution in the water along the North American coast is not caused by oil tankers and oil rigs at sea. Most of the oil pollution comes from sources on land. For example, when it rains, oit that lawn mowers leave on lawns and oil that cars leave on streets and parking lots runs off. This runoff is carried out by streams and storm drains to rivers, bays, and the sea, killing marine life along the way. According to the report, 85% of the 29 million gallons of marine oil pollution in North America comes from individual users - not the oil industry"
