see, the reason it's worth learning how the world of geopolitics works, whether or not you like it, is because you find out a significant feature of the global political economy is that water in the US gets wasted on mass producing alfalfa that will then be sent to saudi arabia to feed livestock
if we stopped growing alfalfa in deserts to feed cows in saudi arabia basically all of the west's water problems would be solved without anything else having to change (And denver is on the wrong side of the continental divide for that discussion)
