Now that I think about it, Americans and Western Europeans have less to worry about than most. If we were to actually approach this scientifically, it would be most effective to infect populations with the highest birth rates. Developed countries have the lowest birth rates so we'd be less of a focus. In other words, Africa, parts of Asia, and the Middle East would be (to use Mahmoud Ahmadickhead's words) "wiped off the map." I'm sure, as a scientist, Dr. Pianka is well aware of this. I suspect he is a closet Nazi.
