you always come up with the same "ocean clean up" machines but did you find a way that PREVENTS millions of tonnes of plastic from reaching the environment/ocean yet, because at this pace cleanups will NOT change the situation... they cannot pick it up fast enough from the oceans/rivers, I am afraid.

A REAL conscious capitalist would first worry about plastic production...

go to the supermarket and see how much plastic you take home... HOW DO YOU ELIMINATE THAT is key... and because you also assume that at the pace we dispose of plastic in the environment that the "ocean clean-ups machines" be able to recycle 100%, yes maybe for a while... then the brick wall will present itself.

conclusion: come up with a solution that STOPS plastic production at the household level... then prepare for another economic crash :)
