Fist, GMO is a tech, and the glyphosate-producing produce is just a fraction of it.
Because of this ridiculous anti-science movement, there are GMO crops that could be a huge help to certain third world countries that are being held back just so that Whole Foods can sell more alternative medicine quack cures, GMO-free meat, and fat-free sugar.
Second, the only scientifically proven negative effect of glyphosate-producing GMO produce is that it will eventually lead to weeds that evolve a resistance to glyphosate. That's it. That's the worst thing anyone can prove about the scary scary glyphosate-producing GMO: that we will eventually have to stop using it because of evolution.
There is no scientific basis for any of this anti-GMO crap. It's just a bunch of nonsense pushed by people because if they can make people doubt evidence-based science, then people will be more inclined to buy health products that are not based on evidence (namely alternative medicine).
