美国制造最多塑料垃圾
Biggest plastic waste producer When the US Environmental Protection Agency released its plan recently for addressing marine litter, it named five Asian nations as responsible for more than half of the plastic waste flowing into the oceans every year. But the US is by far the world's largest generator of plastic waste. Now, new research, published in Science Advances, reexamines the US's role as a plastic consumer and concludes that the country has much more work to do at home to manage its waste. It produced about 42 million metric tons of the stuff in 2016. Although the US accounted for just 4% of the global population in 2016, it generated 17% of all plastic waste. Meanwhile, less than 10% of American plastic waste is recycled, and the US has a 30-year history of shipping half of its recyclable plastic overseas, primarily to developing nations lacking the infrastructure to manage it. |
