Plastic Waste and Marine Life

What is one major impact of plastic waste on marine life?

• Increased oxygen levels in the ocean.

• Improved habitat for marine species.

• Reduction of ocean temperatures.

• Ingestion of plastic by marine animals.

Name two types of plastic pollution found in oceans.

• Heavy metals and sewage

• Microplastics and macroplastics

• Glass debris and rubber tires

• Biodegradable waste and oil spills

How does plastic waste affect the quality of water in rivers?

• Plastic waste improves water clarity and quality.

• Plastic waste has no impact on river ecosystems.

• Plastic waste provides nutrients to aquatic plants.

• Plastic waste contaminates water with harmful chemicals and disrupts aquatic ecosystems.

What are microplastics and how do they enter the ocean?

• Microplastics are large plastic items that float on the ocean surface.

• Microplastics are small plastic particles less than 5mm that enter the ocean through runoff, wastewater, and the breakdown of larger plastics.

• Microplastics are biodegradable materials that dissolve in seawater.

• Microplastics are naturally occurring minerals found in ocean sediments.

List one effect of microplastics on marine animals.

• Ingestion of microplastics can cause physical harm and digestive issues in marine animals.

• Microplastics improve the water quality in oceans.

• Microplastics provide essential nutrients to marine ecosystems.

• Microplastics enhance the growth of marine animals.

What is a common source of plastic pollution in oceans?

• Glass bottles

• Biodegradable materials

• Single-use plastics

• Metal cans

How can plastic waste disrupt the food chain in marine ecosystems?

• Plastic waste improves the health of marine organisms.

• Plastic waste disrupts the food chain by causing ingestion and toxicity in marine organisms, leading to health issues and bioaccumulation of toxins.

• Plastic waste has no impact on marine life.

• Plastic waste enhances nutrient levels in the ocean.

What are some ways plastic waste can affect human health?

• Plastic waste can lead to chemical exposure, microplastic ingestion, respiratory issues, and hormonal disruptions.

• Plastic waste has no impact on wildlife.

• Plastic waste can enhance soil fertility.

• Plastic waste can improve air quality.

What role do ocean currents play in spreading plastic pollution?

• Ocean currents help to decompose plastic materials quickly.

• Ocean currents spread plastic pollution by transporting debris across distances and concentrating it in specific areas.

• Plastic pollution is only found near coastlines, not in open water.

• Ocean currents prevent plastic from entering the ocean.

How do larger pieces of plastic waste break down in the ocean?

• Plastic waste is consumed by marine animals without breaking down.

• Larger pieces of plastic dissolve completely in seawater.

• Plastic waste turns into organic matter through chemical reactions.

• Larger pieces of plastic waste break down into smaller fragments through photodegradation and mechanical processes in the ocean.
