Only in the way that can be monetized or industrialized, and only if we actually cut down on emissions (instead of just slowing the growth rate a little)

There’s plastic bottles everywhere. There’s people everywhere. What if every human spent an hour a day on little algae bioreactors? It’s grade school level science, all you need is bottles, non-potable water, a knife, and any old cloth to strain it out.

And, of course, algae… But once you get started, that’ll be easy to come by. It’ll even naturally adapt to local conditions, and there’s versions that can be used as food - the rest can be dried and used as fertilizer. It not only provides nutrients and increases water retention, it also helps mycillium regrow, repairing the soil. This also reduces runoff and feeds into water tables

Ever since this idea popped into my head, I’ve felt there’s something there - I met someone working for a company that is doing this commercially, and I can’t help but think if we can do it in a distributed manner it could help with a lot of issues
