But, what do we know? We know that in nature bt kills insects. SO, your claim that it can't hurt a fly is already suspect.
We know that when BT is inserted into a plant, the plant produces the toxin internally in grain or other cells.
We also know that the plant then produces the toxin 1000s of times more than would ever be used as a topical pesticide.
We also know that study after study are coming out showing the gene to be toxic.BT cotton feed has been implicated in animal toxicity, infertility and, even, deaths. Do a quick google search on the effects in India of Bt brinjal and sheep who graze of the BT cotton.
You don’t know. Go do your homework.
” sheep who graze of the BT cotton. “
Controlled studies show that sheep that graze on bT cotton have no problems.
Interesting how this unconfirmed story from India has become such a strong point from the anti-GMO group.

“The Officers of the Department of Agriculture of the Warangal District we met said that sheep death cannot be attributed to Bt cotton and that residual pesticides are probably the cause, and sheep died even before Bt cotton was cultivated in the area.”

The amounts of Bt protein produced by all crops combined in the U.S. on an annual basis is much lower than the amount of chemical sprays used, to the point that it doesn’t contribute much to the total pesticide use.
