Abstract
The US is the third-largest contributor to plastic pollution in coastal environments, according to a new paper in Science Advances (2020, DOI: 10.1126/sciadv.abd0288 ). The paper builds on work published in 2015 in Science by Jenna Jambeck of the University of Georgia estimating that 8 million metric tons (t) of plastic waste ends up in the ocean every year because of bad waste management practices. The 2015 paper pointed to China and Southeast Asian nations like Thailand and Malaysia as leading sources of the waste. It ranked the US 20th. The new study, led by Kara Lavender Law, professor of oceanography at the Sea Education Association, and coauthored by Jambeck, takes into account US exports of waste plastic, ostensibly for recycling, to countries with leaky waste management systems. It estimates, based on 2016 data, that up to 1 million t of waste plastics might have ended up in the ocean
