>>1285041>solution - pipeline. I don’t know why we don’t have a network of interstate water pipelines already1. States not on fresh waterways don't have rights to that fresh water
2. That'd be ridiculously energy and resource intensive
3. You'd completely fuck the ecosystems you take the water from because the water would be returned to a separate water system. Even if you completely banned people using their water outside of their homes, which good luck enforcing that, you'd still lose a metric fuckton to various bullshit along the way.
4. Oh and you'd have to treat it and pump it back just to limit some of the damage.
A much better solution is killing all the cows, tearing up all the lawns, and telling all the dumbshit farmers doing shit like growing alfalfa in a fucking desert to sell to overseas so they consume enough water to not lose their preferential water rights to cut that shit out. Won't fix everything, but would certainly extend the number of areas that can support human life by quite a bit. Don't want to end up like those cities in India that are literally almost out of water and going to have to be systematically abandoned.
Oh, and desalination long term. Cost is going to be a metric fuckton, but it will be less than abandoning the southwest.
As for the flooding in the South? Nah, that shit's just fucked. Area's overbuilt for no god damn reason.
