This is all our hope imo. There's been bacteria and fungus evolving to eat this stuff. We give life an abundance of something containing energy and so life evolves to make the best of it. I am sure, even now, that there is an animal somewhere with gut microbes evolved enough to let it survive solely on eating plastic. Like some plastic termite, ig

With all of these plastics going into the food chain who's to say we won't have a massive convergent evolution of microbiomes dissolving plastics?

The current census seems to be breeding for an extremely powerful enzyme and hopefully using that en masse to break down plastics before they even reach the ocean.

​

Another idea would be running massive septic tanks with these microbes, growing them with plastic, and using them in other applications.
