  5. OR&R's Emergency Response Division (ERD) responds to roughly 200 marine pollution-related incidents throughout the U.S. every year — we respond to larger and more complicated oil spills where scientific support is needed, but there are thousands of other spills that occur in U.S. waters. For many of these incidents the source of the spill is not a large freighter or an oil platform, but rather small recreational and work vessels, such as fishing boats

Marine habitats worldwide are contaminated with man-made debris. Oil spills remain a concern, though actual spills have decreased steadily for several decades

Marine pollution from land-based sources is first of all a problem of individual regions; however, the consequences of regional failure, such as the loss of nearcoast biological diversity and, in particular, of corral reefs, makes land-based marine pollution a core global problem, too Marine pollution refers to the contamination or presence of pollutants in oceans and seas. The word 'marine' comes from the Latin word for 'sea' and it is related to similar words, such as 'mariner'. Ocean pollution is become ever more of a problem in the present day Marine pollution, 80% of which is generated by land-based activities, is having a devastating effect on our oceans. As well as degrading habitat, pollution directly threatens marine animals and plants, some of them rare and endangered. Oil spills can be catastrophic, but not all the oil that enters the sea leaks from ships Ocean pollution, often also referred to as marine pollution, can be defined as the contamination of our oceans with harmful substances like plastic, oil, heavy metals, particles and other substances that may hurt a variety of sea animals and plants.
