Everybody lives in an area with potable water. Without potable water, they
die.

That's nice, but it doesn't mean there's enough. There are places where
people are JUST BARELY able to get as much water as they need, which creates
very tense interactions with neighboring countries. Yeah....the water's
there somewhere, but some countries don't have the resources to get it where
it needs to be.
