Coastal and Marine Pollution


Approximately 85 percent of commercially harvested fish depend on estuaries and coastal waters. Coastal and marine pollution is a change in the physical, chemical, or biological characteristics of the ocean or sediments, which results from contamination by human wastes and can affect the health and survival of all forms of life, degrading the natural quality of the ocean and coastal environments. Physical pollution includes plastic bags and discarded fishing nets that can strangle sea mammals and cause smothering from oil. Physical pollution can also be the lack of nutritious sediments held back by dams. Severe water pollution has come from urban and agricultural runoff that lowers oxygen levels in estuaries, sounds, and gulfs, harming fish and shellfish stocks, as well as from offshore waste dumping and oil spills.

The largest oil spill in world history was the Gulf War oil spill, in the Persian Gulf in January 1991. Experts estimate the amount of crude oil spilled was well over 5 times that of the Exxon Valdez oil spill of 1989. The spill was caused when Iraqi military forces opened oil valves near Kuwait City during the first Gulf War, and endangered wildlife habitats throughout the coast of the Arabian peninsula, bringing some to call it this one of the worst acts of "environmental warfare."
