This garbage patch, formed by circular wind patterns called gyres, has been described by many as a floating island of trash. Some of the main sources of ocean pollution are oil, plastic and agricultural waste and it is estimated that 80% of this pollution originates from land. As technology progresses worldwide, we must work together to formulate a plan to clean up our oceans as well as prevent contaminates from reaching our waterways in future years. “It has been estimated that plastics and discarded fishing gear, such as monofilament line and discarded nets, kill one million seabirds and 150,000 marine mammals each year” (Ambrose). Trade winds and gyres in the Atlantic and Pacific oceans can carry trash thousands of miles. When the currents caused by these winds intersect with land, the garbage is deposited on the shores of continents and many islands off the coast. Another major source of marine pollution is pollution via petroleum products and oil spills. An oil spill large enough can completely destroy an environment for tens of thousands of marine animals. “In the period from 2000 to 2008, an average of 24 tons (21.8 metric
