Don't be surprised at the claim. It has the same unscientific basis by which Obama says "___ jobs saved or created."
On the other hand, the ban on DDT has led to hundreds of thousands of African deaths each year. This is directly provable, because they died from disease x (malaria) that could have been prevented by action y (spraying pesticides).
Thanks for the link. I have responded to your comment, and agree with you to a large extent. It is a sad reflection of our society that claims such as this are accepted and supported by the eletes who really should know better.
