Depending on which figures you believe, if every single lawn in California were left to die California would save somewhere between 1-2.5% of its water. I question whether the cure is worse than the disease.
I've cut back on shower times, I never wash my car, I've allowed my backyard to die and I barely water my front yard. I even put a bucket in the shower while I allow the water to heat up--and I water my orange trees with that water. Heck, I even brush my teeth out of a cup so as not to leave the water running. I say all that to demonstrate that I don't support wasting water, and I practice what I preach.
But let's be honest--domestic use is only about 10% of water use in California. If all homes were to stop using all water, we'd save that 10%. In other words, these personal cuts and drastic fines that Governor Brown wants to impose are for show only, they don't really do anything to make water available to Californians. He and his ilk have fought new dams in this state for most of my life--that is why we're running so low on water. His condescension regarding "your nice little green grass" is Obama-like. It's typical of the "I know what's best for you" liberal, but it's not good leadership or good stewardship.
