Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [1] [2] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [3]
How bad is the world’s plastic problem? Few disagree that the level of pollution has reached alarming heights. Between 2000 and 2019, annual production of plastics doubled to 460 million tons.
In 2016 alone, the U.S. produced 42 million metric tons of plastic, equating to about 286 pounds per person, according to a paper published in Science Advances in 2020 -- nearly more than the ...
Studies have shown that pumping milk, freezing it in plastic bags, then subsequently heating it up will increase the contamination of microplastics in the milk. [38] Similar results have been seen from heating plastic reusable food containers in a microwave, showing the release of both microplastics and nanoplastics.
A growing number of countries have instituted plastic bag bans, and a ban on single-use plastic (such as throw-away forks or plates), and are looking to spread bans to all plastic packaging, plastic clothing (such as polyester and acrylic fiber, or any other form of unnecessary plastic that could be replaced with an easily biodegradeable, non ...
