This excerpt is from the NRDC.. hardly a pro-chemical group, on the disappearance of bees...
"Scientists studying the disorder believe a combination of factors could be making bees sick, including pesticide exposure, invasive parasitic mites, an inadequate food supply and a new virus that targets bees' immune systems. More research is essential to determine the exact cause of the bees' distress."
Maybe it is pesticides. But stating "maybe" as fact happens all to often and muddies the issue. I would add... bees in this case are domestic bees. Maybe they can be made resistant to said pesticides. Or are all pesticides just bad because they are bad no matter what?
