re: how about a bet on DDT?
Your first link is to Steve Milloy, a worse hack than Benny Peiser. And that is relevant, not ad hominem, because you can't trust a thing he says.
Your second link contradicts what I understand to be World Wildlife Fund's position, that it does not advocate a complete ban on DDT. I'd have to dig some more about this.
Environmentalists who oppose DDT use for agriculture while not opposing it for vector control have saved lives, while hacks like Milloy that support ag use have killed people by increasing mosquito resistance to DDT used for vector control.
Bets, anyone?
