Ocean Pollution
Ocean Pollution “Over 80% of marine pollution comes from land-based activities” (WWF, May 4, 2006, p.1). The rest comes from ocean-based activities. Different types of pollution enter the ocean each year. The major pollutants are oil, toxic materials, and debris. These materials not only pollute the ocean, but they also affect the marine life. Before the 1970s there were no laws to prevent and stop people from dumping pollutants into the ocean. Since the early 1970s many laws and regulations have been passed to help protect the ocean. People have set up organizations. These organizations go as far to have beach clean ups and offer several tips for people to do their homes that will help keep the ocean clean. Ocean pollution is something that could be easily avoidable if people just take time to dispose of trash properly. Oil pollution is one of the sources of ocean pollution. According to New Internationalist magazine the annual average worldwide input of oil into the oceans was about 1,269,000 tons in 2003. This was a big difference compared to 3,250,000 tons in 1983. there are three types of oil that pollute the ocean. The first type of oil that pollutes the ocean is crude oil. It comes from natural seeps. Natural seeps are cracks in the ocean floor that leaks oil into the ocean. The oil seeps slowly into the ocean. Because it seeps slowly the marine life can adapt to it. In North America the Gulf of Mexico and off the southern shores of California is where the natural seeps are located.

The second type of oil that pollutes the ocean is oil spills. Oil spills occur during the extraction and transporting of oil. “Oil spills cause huge damage to the marine environment-but in fact are only responsible for only around 12% of the oil entering the seas each year” (WWF, 2006, p.1). Extraction takes place near or on shores and this can cause risks for the coastal environment if there is a spill or leak. During extraction
