This post from Andrew Revkin over at Dot Earth (one of my favorite blogs) gives a great example of the "doomsayer" Paul Ehrlich-type population point of view vs. the Paul Simon-type "cornucopian" view. Even has a video clip from each...
I try to be an optimist, but I can't get away from what Garrett Hardin said about Simon and his cornucopian world-view: "Simon really should have taken an elementary math course before he said anything about the consequences of the human population."
