We’ve also already depleted many aquifers past the point of recovery.

We have too many people to hydrate, too many crops to water in order to feed them, and not enough water. At some point widespread desalination is probably inevitable, but that requires a lot of energy.

Or the public could accept a reduction in their standard of living, but that’s likely not happening without a civil war.

Wait till you find out how much uranium there is in coal ash and how many tons a year are put in the air or dumped into ground water. Both the ash and uranium tailings are in the 50ppm range, but we make 100Mt per year of one of them and basically no uranium tailings in the US. Globally, the ratio is over 1Gt of coal ash and 10-20Mt of uranium tailings.

One is currently a problem, the other isn't.

and we've collected enough arsenic from a single mine to kill every human on the planet 300 times over in one spot- what's your point? That because we screwed up one spot we should give up?
