According to Genesis, after God made man he looked at all of his creations:  "God saw every thing that he had made, and, behold, it was very good."

But for environmentalists, it was almost all very good.  Except for the people part.  Namely, other people.  Since the '60s, environmentalists have been screaming at us that they hate people:  One of their unending quests has been, since that time, for depopulation.  But sometimes they have been more explicit:

"It'd be little short of disastrous for us to discover a source of cheap, clean, and abundant energy because of what we would do with it."  -Amory Lovins

"Giving society cheap, abundant energy at this point would be the moral equivalent of giving an idiot child a machine gun."  -Paul Ehrlich

The environmental left have had the same solutions to our problems since way before we had our problems.  And yet they think of themselves as "scientific."

There are no plain and simple problems any more. From poverty to race to crime to Vietnam, all we face are crises which threaten to bring down the world upon our heads.  –Ben Wattenberg, The New Republic, “The Nonsense Explosion,” 1970
