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.
