I know as lot of water use in CA is in the agriculture sector, but we seriously need to stop having yards with grass and golf courses need to go too. Especially in the freaking desert, like in Vegas (which might as well be California). Part of the problem you hit perfectly,
@Jan, is that rather than have a rational plan that starts to conserve and limit use to the necessary, we're letting idiots use up the resource on their vanity projects as if it's infinite. The consequence of course is that the poor will get screwed as the rich will get and control the last of the resource. Our failure to reign in these most destructive tendencies of capitalism shows just how coopted American democracy has become by the oligarchs. We're really in a terrible position as life itself is under threat and those who control the levers of power don't give a crap.
