> ~45% of the total US ***domestic*** water usage is used to water the lawn Hmm. "Domestic"... Sure that does'nt amount to ~1% of the total ? The farmers that live an hours drive upstream of me pay a penny for a dollar's worth of water here. Unless I was an industrial user, in which case I'd pay 2-20 cents, depending on where I fit into the pecking order. You notice the loudest advocates of "markets" don't talk about "free", or "efficient" markets.
