2022年5月9日 · Plastic waste makes up 80% of all marine pollution and around 8 to 10 million metric tons of plastic end up in the ocean each year. Research states that, by 2050, plastic will likely outweigh all fish in the sea. In the last ten years, we have produced more plastic products than in the previous century.

2023年3月8日 · More than 171 trillion pieces of plastic are now estimated to be floating in the world's oceans, according to scientists. Plastic kills fish and sea animals and takes hundreds of years to...

Plastics make up a significant portion of marine litter, with estimates suggesting that more than eight million metric tonnes of plastic enter the oceans every year. Plastic waste, ranging from microplastics to large debris, continues to accumulate in marine environments, posing a severe threat to our ecosystems.

Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which …

2024年9月23日 · Plastic pollution has become one of the most pressing environmental issues, as rapidly increasing production of disposable plastic products overwhelms the world’s ability to deal with...

In the marine environment, plastic pollution originates primarily from land runoff, but includes paint shed from shipping, discarded fishing gear, and more. Due to solar radiation, wind, currents and other natural factors, plastic breaks down into microplastic (smaller than 5 mm) and nanoplastic (smaller than 100 nm) particles.

2022年12月2日 · An estimated 11 million metric tons of plastic enters the ocean each year. Often stemming from poor waste management, plastic pollution is a major environmental issue because most plastics do not biodegrade and instead break down into microplastics.

2023年12月30日 · There is an estimated 75 to 199 million tons of plastic waste currently in our oceans, with a further 33 billion pounds of plastic entering the marine environment every single year. This constant flow of plastic production is simply too much for existing waste management and recycling infrastructure.

The health, resilience and productivity of marine and coastal ecosystems is increasingly affected by pollution, including land-based nutrient, pesticide and plastic pollution. WWF and our supporters have worked to raise the public and political prominence of plastic pollution, creating opportunities for coordinated action from the local to ...

2025年1月18日 · In the ocean, plastic pollution can kill marine mammals directly through entanglement in objects such as fishing gear, but it can also kill through ingestion, by being mistaken for food.
