Marine DebrisSource: National Oceanic and Atmospheric AdministrationMarine debris is a persistent pollution problem that reaches throughout the entire ocean and Great Lakes. Our ocean and waterways are polluted with a wide variety of marine debris, ranging from tiny microplastics, smaller than 5 mm, to derelict fishing gear and abandoned vessels. Worldwide, hundreds of marine species have been negatively impacted by marine debris, which can harm or kill an animal when it is ingested or they become entangled, and can threaten the habitats they depend on. Marine debris can also interfere with navigation safety and potentially pose a threat to human health.All marine debris comes from people with a majority of it originating on land and entering the ocean and Great Lakes through littering, poor waste management practices, storm water discharge, and extreme natural events such as tsunamis and hurricanes. Some debris, such as derelict fishing gear, can also come from ocean-based sources. This lost or abandoned gear is a major problem because it can continue to capture and kill wildlife, damage sensitive habitats, and even compete with and damage active fishing gear.   3Select the correct answer.What is the key idea of this passage? A. Littering is harmful to the water supply and marine life. B. Marine pollution is not only devasting to marine life, but to human health. C. Hunting and water sports are endangering the safety of marine life. D. People are the main cause of marine pollution.

Most marine debris is composed of plastic whose industrial production and commercial use are projected to increase exponentially over coming decades.Which of the following initiatives would have the greatest impact on reducing plastic waste in the marine environment?AImplementing responsible disposal policies for existing types of plastic in order to prevent end-of-life materials from entering the marine environmentBPreventing the production and consumption of environmentally persistent types of plastic such as PET via purposeful legislation and regulationCIncreasing awareness and promoting population behavioral change, as well as giving consumers incentives to recycle persistent materialsDImplementing all of the above strategiesEI'm not sure

Propose ways that plastic pollution might decrease the biodiversity of a marine ecosystem.

What are the problems with large quantities of plastic within the ocean?Question 19Select one or more:it remains in the ocean and doesn't go awaythere is no way to solve the problemit floats and is mistaken for food by birdsit breaks down into smaller particles called microplastics

Fishes are especially vulnerable to tiny bits of plastics floating in the ocean, called microplastics, because:The microplastic bits look like food for fish that feed on marine microbes.Microplastics accumulate in predatory fish, asthey cannot be broken down and metabolized by the fish.They breathe water through their gillsAll the statements are the reasons why fishes are vulnerable to microplastics
