I direct your attention to this wonderful group of people:
https://theoceancleanup.com/

They have created a passive plastic collection system that will be able to gather up most of the ocean plastic in a remarkably short amount of time. But they are not stopping there. They are getting at the root of the problem by cleaning up the world's most polluting rivers with another passive collection system for rivers!

Capitalism working at its best. :-)

Of course, not nearly as good as earthcustodian doing nothing but complaining day after day, while hypocritically gathering evil money to get her nails did.
