Iirc, most of the plastic isn't even from rivers. It's from the fishing industry, illegal trash dumping and the wear on car tires.
Hi Downvoters, please explain what is factually wrong about my comment. Thanks.
"A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers, eight of them in Asia."
10% from fishing industry
Not sure what you mean by illegal trash dumping. Trash that's dumped directly on the coast and not into a river first?
Trash that's illegally dumped off shore. It's harder to dump large amounts of trash in a river and not have somebody notice - it's easier to say you're transporting it and "lose" part/all of it while at sea.
85% comes from either rivers or shorelines.
A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers [...] The 10 rivers that carry 93 percent of that trash [...], so 10 rivers are said to contribute 25% of total trash and 93% of river-trash. That'd leave ~68% from the shore, which sounds very high.
https://ourworldindata.org/plastic-pollution#ocean-plastic-s... also has more input if you're interested.
From the article:
>A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers, eight of them in Asia.
>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.
So to say "10 Rivers Contribute Most of the Plastic in the Oceans" is not really correct, they contribute something like 25%.
