(37,072 posts)In any event, vertebrates lack receptors to bind it, so it's NON TOXIC except to target insects. AND it's only stable for short times when buried, because sunlight breaks it down rapidly. For crying out loud, Bt is the answer to every organic farmer's prayers. All this bleating about it having a different crystalline structure in bacterial expression and transformed plant expression is utterly beside the point. You might as well argue about it being purple rather than yellow. It's still non toxic to all but target insects because only they have the gut physiology necessary for its toxicity.
Look, I'm not a fan of Bt transformed crops, not because I fear genetic engineering, but because I'm an entomologist and fear induced resistance to one of the best, most benign insect population management tools we've ever had. The whole history of the pesticide industry can be summarized in one sorry statement: Where a gram is enough, use a ton. THAT is the real danger of Bt transformation-- it hastens the development of insect resistance by favoring resistant population fractions.
In my experience, most proponents of anti-GMO labeling, etc don't ever get far enough past their simple and irrational fear of things they don't understand to actually pay attention to WHY Bt transformed crops might or might not be a bad thing, or whether their real beef is with the business practices of predatory corporations like Monsanto.
