Yep. Though there is no water SHORTAGE--the problem of distribution and purity is definitely going to be with us for as long as there are nations too poor to do anything about the infrastructure needed to distribute drinking water. (Landlocked deserts are just pretty much stuck.)

(Landlocked deserts are just pretty much stuck.)Not only that, but irrigation for farming in dry lands has some very delitorious effects over time. Over time, it concentrates certain minerals and such at the surface until they reach unacceptable levels. Large parts of our midwest are now more or less unfarmable between the problems of that and dropping water tables. Fortunately we don't need them all to raise food on.
