Abstract
    In the past 30 years, the use of plastics and other synthetic materials has expanded at a rapid pace. The accumulating debris poses increasingly significant threats to marine mammals, seabirds, turtles, fish, and crustaceans. The threats are straightforward and primarily mechanical. Individual animals may become entangled in loops or openings of floating or submerged debris or they may ingest plastic materials. Animals that become entangled may drown, have their ability to catch food or avoid predators impaired, or incur wounds from abrasive or cutting action of attached debris. Ingested plastics may block digestive tracts, damage stomach linings, or lessen feeding drives. Developing information suggests that the mechanical effects of these materials affect many marine species in many ocean areas, and that these effects justify recognition of persistent plastic debris as a major form of ocean pollution.
