An aside: Organic farmers use Bt too. As a spray. Bt proteins are a naturally occuring substance, after all. They argue the spray is not as bad as the GM crops

An aside: Organic farmers use Bt too. As a spray. Bt proteins are a naturally occuring substance, after all. They argue the spray is not as bad as the GM crops due to the timing of exposure. I really don't know enough about insect biology to say if that makes sense. Glyphosate is certainly not a sustainable weed control solution but it's no worse than the herbicides that it replaced. I wonder if the biggest negative impact of biotech firms is not the chemicals but on IP and patents, hindering the positive development of GMOs, and to what extent proprietary software IP and patent rulings paved the way for them.
