\nSustaining the planet means widely different things to all of us\u2014so let\u2019s try and define our aim. The phrase surely isn\u2019t meant literally. Terra was sustaining herself just fine for millions of years before the first oxygen-producing lifeforms infested her and wrecked her nice methane ecosystem, dooming entire phyla to extinction. Mother Gaia\u2019s not alarmed by \u201cglobal warming\u201d: she\u2019s survived vastly greater environmental changes more than once, and will again.
