I agree, more or less, but I believe that the "We can't possibly predict the effects of this therefore we can't take the risk" argument demands more urgent opposition. I argue that we can predict the effects. They're tiny even in absolute terms, and the uncertainty is well-understood and also small. And in relative terms - These small risks and effects are weighed against a half-million lives per year. I'd be willing to release kudzu or rabbits to save that many lives; eliminating mosquitoes has such insignificant risk relative to its benefit that that risk doesn't even register. Do it now.
