Actually, the central figure of the piece -- one Alan Weisman -- proposes more than evacuation. He's trying to organize a voluntary human extinction movement. Weisman's Leftist pedigree is quite evident in his affiliation with Homelands Productions.
Weisman is an extreme example of what I said here:
The emphasis on social restraints -- to a Leftist... -- means social engineering writ large. He wants a society that operates according to his strictures. But society refuses to cooperate, and so he conjures historically and scientifically invalid explanations for the behavior of man and nature. By doing so he is able to convince himself and his fellow travelers that the socialist vision is the correct one. He and his ilk cannot satisfy their power-lust in the real world, so they retaliate by imagining a theoretical world of doom. It is as if they walk around under a thought balloon which reads "Take that!"Weisman isn't content to foresee the apocalypse. He wants to rush toward it and embrace it.
