I don't have the link to it here, but they showed how it was killing bees and they told us some facts that were rather scary about the stuff.
There's enough poison on one corn seed to kill 100,000 bees. It takes two nanograms of this poison to kill a bee. The air and dust coming out of the sprayers are 700,000 times stronger than that. I looked at those figures when I first heard them and I thought somebody was just saying that, but having seen the webinar, I have to take the word of the researchers who did that. It wasn't just somebody spouting off. I could see this stuff was pretty potent.
Just as a note, the EPA has linked this stuff to also affecting warm-blooded animals, and some of the things it's doing to them are quite horrendous.
