I ran across this in a northern California suburb this week. It's a scene alright.
But seriously, retiring our lawns (and some golf courses, perhaps) is one of the responses most of us probably will be forced to make to global warming. California mountains will get less snow; we just won't be able to continue to surround every house with a patch of lush green grass.
A 2006 report from the Public Policy Institute of California spelled out the problem.
Sometime down the line, we're going to have to retire some of those lawns. The mini-gnomes will remain optional, I certainly hope.
