I wasn't using "green" in that sense. That, of course, is an alternative. If one is merely looking to use as little resources as possible for, say, food production, it'd probably be best to vacate all arid and semi-arid regions and just farm those regions that're already better suited for agriculture. (As a tie in to this, remove subsidies for agriculture too, including water reclamation projects that only prop up projects that are actually relatively resource inefficient.)

I don't think it's off the table. My proposal was to get the whole desert back as a region that could be used by humans for agriculture, forestry, grazing, etc. in the more conventional sense.
