This is great, and should be done. But we also need to stop it happening again. Which means stopping fishing nets and plastic trash from being dumped in the sea by ships. And preventing plastic that is dumped into rivers in developing countries [1] from reaching the sea. These are hard problems. [1] https://www.science.org/doi/10.1126/sciadv.aaz5803

> African You have heard wrong. Then again: "More than 1000 rivers account for 80% of global riverine plastic emissions into the ocean" https://www.science.org/doi/10.1126/sciadv.aaz5803 Has some nice maps of waste versus country: https://www.science.org/doi/10.1126/sciadv.aaz5803#F4 "Around 90% of all river-borne plastic that ends up in the ocean comes from just 10 rivers" https://www.weforum.org/agenda/2018/06/90-of-plastic-polluti... Not necessarily contradictory, but an indication of disagreement.
> https://www.science.org/doi/10.1126/sciadv.aaz5803 I don't see a comment in that article about the original provenance of the waste in rivers - can you paste it?
I’m not sure what those figures are for. They list India with 126.5 million kg of plastic “dumped”, yet the Phillipines is #1 with nearly 3x that amount of plastic waste going down its rivers into to oceans: 360 million kg (3.6 × 10^5 Metric tonnes) of plastic waste according to https://www.science.org/doi/10.1126/sciadv.aaz5803
