Whenever I think of Geo-Engineering I imagine someone getting into keeping reef aquariums, noticing some fish are looking less than healthy, testing and seeing chemical/physical properties of the tank are off, adjusting by adding/removing some chemical only to see everything die anyway, and then coming to the realization that maybe this hobby is a lot more nuanced then they imagined and isn’t for them.
Perhaps next time we’ll just get a freshwater planet, I hear those are much more forgiving ;)
