People can’t get their head around our depleting fresh water resources because in the U.S., besides a couple small California communities, the tap hasn’t run dry. When things fail in capitalism it’s more of a gradual thing. Supply goes down, price goes up, things get scarcer and scarcer. But running out of water isn’t like this. It’s binary. There is running water and then there isn’t. And you can bet if LA or Las Vegas suddenly ran out of water there would be mass hysteria. But nearly running out of water feels just like having all the water in the world (because of the way the taps work). So people are easily fooled.
