See, stuff like this is what (deservedly) gives enviro-whackos a bad name. It's hard me to accept that the phrasing in the title of this post is entirely tongue-in-cheek. "May be"? Excuse me? It's almost like they approve. See all those "Life After People" type shows and books for examples of their fantasies. (List at the bottom here.)
And then comes Momma Nature to remind us that what we do means diddly squat in the long run. :-) Maybe not this time, but there was once a very frightening illustration of this in National Geographic. (Although I'll admit I didn't quite see it right the first time, perhaps because of how they presented it.)
Meanwhile, the One doesn't really seem to care, which is here, as elsewhere, the main feature of his and both our salvation as well as the danger. (Of course, wouldncha know it's all the GOP's fault, as always.)
Apropos of nothing- or maybe so- I think the way someone responds to this story (I can think of two main possibilities) would tell you most of what you need to know about their views.
