IE what are the areas we should be seeking to migrate as many people as possible to before shtf.
Not everywhere needs that strict water rationing, what about the very few parts of the globe that have an excess of fresh water?
My point was that you can survive on 3 L of water per day.
We have overstretched our carrying capacity in numerous places around the globe. The solution is not to employ technology, the solution is to change our relationship with our environment.
As other people have said, “just running a big pipeline thousands of miles” could have unforeseen ramifications, and as different people have said, what appears to you as an “excess” of fresh water is something that ecosystems are founded upon.
As someone who lives in a region where freshwater is plentiful and is predicted to stay plentiful for the next century or more, I know this sounds a bit selfish of me. But then again, my region can support lots of water refugees; with a little intelligent planning we could probably support upwards of 500 people per square mile, without fossil fuels or daily imported goods.
