In some regions, such as much of the American southwest, demand for water is too high for how much water they get, they're covering the difference with fossil aquifers but those are finite and rapidly draining. Most n those regions just pretend that a solution will magically appear some day, maybe they'll somehow get other neighboring regions to pipe all their water over hundreds of miles, but that's a pipe dream. Realistically those areas are too crowded and people need to move to more ecological sensible regions.

Yeah honestly. US urban planning is unfortunately hostile by default, but cities can be dense, efficient, and pleasant if local politics allow it. Unfortunately, a lot of places will block nice things like parks and green spaces, because "the wrong kind of person" might be able to enjoy themselves a bit before or after work.
