> It's "of 57 rivers, 10 contribute 93% of the plastic of those 57"
> Schmidt and his colleagues dug up published data on the plastic concentration in 57 rivers of various sizes around the world. ... > The results, published last November in Environmental Science & Technology, show that rivers collectively dump anywhere from 0.47 million to 2.75 million metric tons of plastic into the seas every year, depending on the data used in the models. The 10 rivers that carry 93 percent of that trash are the Yangtze, Yellow, Hai, Pearl, Amur, Mekong, Indus and Ganges Delta in Asia, and the Niger and Nile in Africa. The Yangtze alone dumps up to an estimated 1.5 million metric tons of plastic waste into the Yellow Sea.
Plastic in the ocean also comes from industrial uses as well as from rivers - about 50% of it is fishing nets.
