Then again - go sell off your house and do it.

Ah, so it wouldn't make a difference if you sold your house. For me, it would make a difference if someone did that and donated all the money to me. It would let me produce way more humanitarian aid and send it out to people in need. It would let me hire more people, expand the business and ultimately save more lives.

We aren't protecting anyone. You are just saying empty buzzwords like "save the planet". Yet you aren't willing to stand by it yourself, and you imagine some billionaire doing it for you. It costs you nothing to want that from them. So they pay infinitely more for it than you, despite the solution not making sense in any capacity and scale.

So again, why should they invest into a fungus that eats 0.2% of all plastic, that needs a specific temperature, humidity, location etc to work, and can probably make as impactful of a change, as if you sold your house and paid people to handle litter better? It's a definition of wasting millions on nothing. It doesn't make sense to do it even with infinite funding since there are better ways to recycle.
