Answer: Ocean pollution is mainly caused by coastal non-point source pollutants. Ships can legally dump wastewater and garbage overboard in some parts of the ocean. At least 85 percent of ocean pollution includes oil toxic wastes and medical wastes.
describe the source of most ocean pollution. is it point-source pollution or nonpoint-source pollution?

Nonpoint source (NPS) pollution is pollution resulting from many diffuse sources in direct contrast to point source pollution which results from a single source. Nonpoint source pollution generally results from land runoff precipitation atmospheric deposition drainage seepage or hydrological modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult. Nonpoint sou…

Nonpoint source (NPS) pollution is pollution resulting from many diffuse sources in direct contrast to point source pollution which results from a single source. Nonpoint source pollution generally results from land runoff precipitation atmospheric deposition drainage seepage or hydrological modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult. Nonpoint source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river or wind-borne debris blowing out to sea. Nonpoint source air pollution affects air quality from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source the long-range transport ability and multiple sources of the pollutant make it a nonpoint source of pollution; if the discharges were to occur to a body of water or into the atmosphere at a single location the pollution would be single-point. NPS may derive from many different sources with no specific solutions or changes to rectify the problem making it difficult to regulate. Nonpoint source water pollution is difficult to control because it comes from the everyday activities of many different people such as lawn fertilization applying pesticides road construction or building construction. It is the leading cause of water pollution in the United States today with polluted runoff from agriculture and hydromodification the primary sources. Other significant sources of runoff include habitat modification and silviculture (forestry). Contaminated stormwater washed off parking lots roads and highways and lawns (often containing fertilizers and pesticides) is called urban runoff. This runoff is often classified as a type of NPS pollution. Some people may also consider it a point source because many times it is channeled into municipal storm drain systems and discharged through pipes to nearby surface waters. However not all urban runoff flows through storm drain systems before entering water bodies. Some may flow directly into water bodies e… Read more on Wikipedia

Sediment Sediment (loose soil ) includes silt (fine particles) and suspended solids (larger particles). Sediment may enter surface waters from eroding stream banks and from surface runoff due to improper plant cover on urban and rural land. Sediment creates turbidity (cloudiness) in water bodies reducing the amount of light reaching lower depths which can inhibit growth of submerged aquatic plants and consequently affect species which are dependent on them such as fish and shellfish . High turbidity levels also inhibit drinking water purification systems. Sediment can also be discharged from multipl...
