Scientists calculated that 275 million metric tons of plastic waste was generated in 192 coastal countries in 2010, with 4.8 to 12.7 million metric tons entering the ocean. This map shows the estimated mass of mismanaged plastic waste from each coastal country; the darker the color, the larger the amount; countries shaded in white were not included.

The marine defaunation experience is much less advanced, even though humans have been harvesting ocean wildlife for thousands of years; the recent industrialization of this harvest, however, initiated an era of intense marine wildlife declines. If left unmanaged, scientists predict that marine habitat alteration, along with climate change, will exacerbate marine defaunation. Image credit: Jenny Huang / CC BY 2.0.
