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.

We're also not even attempting to be smart about our water usage, particularly when it comes to agriculture. Growing crops in a desert that require significant amounts of water to grow is already pretty bad, then exporting the bulk of those crops overseas adds insult to injury.

Of course, all that is made possible by our pants-on-head stupid water rights laws.

We'll also need somewhere to put all that salt. It'd be best to stop the largest wastes of the clean water that we have. We have plenty of water for people and food. We just have to stop the wasteful practices of industry and force them to be more efficient and responsible even though it will eat into their profits.

Solar energy is abundant in the places desalination is most needed. The market will balance out once that becomes apparent to constituents. They will vote to fund solar, politics are only a temporary impediment.

I suspect what we'll actually do is what we always do. Innovate our way into a higher standard of living while simultaneously elevating the poorest people out of poverty and finding novel ways to feed, clothe and house our population.

It's funny how persistent malthusians are in the face of evidence to the contrary.
