And the world does not revolve around kookafornia.
If southern kookie did not suck up every drop of water in the Southwest and waste it THAT Colorado river might not be dry!
The farmers tried to use less water by replacing traditional irrigation with drip irrigation. What happened was that because of the reduced water flow salts and other nasty things started to pile up in the soil. So they had to flood the fields to get rid of these toxins. So there was no real savings.
If you're OK with corn and wheat, and don't want any fresh fruit and veggies then Kookoo-for-Cocoa-Pervs-ornia can pound sand.
But if you're a conservative, and you believe in tradition and contracts, and your forefathers were too shortsighted to see how valuable water would become and failed to retain sufficient water rights then you either have to renege on your contracts or pound sand yourselves.
