Long story in The Guardian about attempts to reduce Dengue Fever incidence using genetically modified mosquitoes & the predictable blowback of hysteria from middle-class Western activists. Now, I am deeply skeptical of GM crops, mostly because of the corporatist economic model on which they are based, but the opposition to the modified mosquitoes is really just an anti-science aesthetic that has noting to do with either the actual science nor with any reasonable cost / benefit analysis. Ask the Cambodian or Vietnamese farmer what he or she thinks about reducing the incidence of Dengue & I suspect you would get a different response than you get from the Western liberals who have the luxury to comment from a safe distance.
Update: On the other hand, I draw the line at this sort of genetic modification. Not so much on the science as on the motive.
