Plastic Pollution is Changing Entire Earth System, Scientists Find

Plastic pollution is changing the processes of the entire Earth system, exacerbating climate change, biodiversity loss, ocean acidification, and the use of freshwater and land, according to scientific analysis. From a report:

Plastic must not be treated as a waste problem alone, the authors said, but as a product that poses harm to ecosystems and human health. The authors gave their warning in the days before final talks begin in South Korea to agree a legally binding global treaty to cut plastic pollution. Progress towards a treaty on plastic pollution has been hindered by a row over the need to include cuts to the $712bn plastic production industry in the treaty.

At the last talks in April, developed countries were accused of bowing to pressure from fossil fuel and industry lobbyists to steer clear of any reductions in production. The discussions in South Korea, which start on 25 November, mark a rare opportunity for countries to come to an agreement to tackle the global crisis of plastic pollution. In 2022 at least 506m tonnes of plastics were produced worldwide, but only 9% gets recycled globally. The rest is burned, landfilled or dumped where it can leach into the environment. Microplastics are now everywhere, from the top of Mount Everest to the Mariana Trench, the deepest point on earth.

The new study of plastic pollution examined the mounting evidence of the effects of plastics on the environment, health and human wellbeing. The authors are urging delegates at the UN talks to stop viewing plastic pollution as merely a waste problem, and instead to tackle material flows through the whole life pathway of plastic, from raw material extraction, production and use, to its environmental release and its fate, and the Earth system effects.
