> There are 10 rivers that cause 90% of plastic pollution

Except, that's not true. The study you're referring to found that those 10 rivers account for 90% of plastic waste going into the ocean from rivers, not all sources[1]. Rivers contribute only 10% or so of the plastic found in the ocean. So not nothing, but far from 90% of all plastic pollution.

Also, probably worth pointing out that quite a bit of that plastic probably originated in the west and was shipped to developing nations to be processed cheaply[2]. Often that amounts to little more than having it burned or dumped into those rivers mentioned.

I personally agree that plastic, when properly stored in a well managed landfill is harmless. But the fact is, that's not happening for far too much waste. Even waste that's used and properly disposed of in developed countries.
