The People’s Republic of China is still the world’s biggest single source of environmental harm. China
overfishes the world’s oceans, blasts
mercury and
nitrous oxide and other pollutants into the atmosphere, and
dumps plastic waste into the sea. It has made progress on many of these problems, but when you’re the biggest global manufacturer, it’s very hard not also to be the biggest global polluter.
China’s most devastating environmental impact has been its emissions of greenhouse gases. Thanks to its unprecedented use of coal, China releases more carbon every year than the United States and Europe combined.
