Even if it takes hundreds of years, I'd just like for humans to live in harmony with nature. Not obsessing over parts per million data or for some hippy reasons, just because it would probably be a beneficial goal. Challenging. But worth it.
Maybe a lot more underground.
Maybe transportation by magnets.
Maybe living and farming where it's naturally green.
Maybe not needing so much power.

I think we're in the 'throw expensive idea shits around all 4 walls' stage of a possibly "greener" future. We're not too sharp. A lot of people want to help and help fast, but it's not a fast job. A lot of people poo-poo the problem, which always happens with any big issue.
Whatever "side" you're on, we're probably in the toddler stage of this thing.
