Once you start squandering ground water year after year because the rains have failed, it's mostly over.

What will go with it is agriculture going to feed meat animals food that can be eaten by humans. Grassland will have to feed animals.

That was the one where cars would stop for pedestrians crossing the street.

Perhaps if we had something like the cap-and-trade system for water, it would encourage them to do so. So would a tax credit for drip irrigation, but our esteemed governor seems to be allergic to tax credits. And then there are historical anomalies like the water district that serves two counties in the Sacramento Valley that controls one-third of the entire Sacramento River based on a claim from the 1870s. Guess where most of our rice is grown?? Might it be possible to redistribute that water more fairly using eminent domain?
