If the argument is that farmers did not plant GMO crops, because bugs would be come resistant, then I'm confused. If the farmers did not plant GMO, then the bugs would eat them. If they did, then eventually the bugs would eat them.
So in the end, the bugs always eat them?
Farmers need to plant non-GMO crops to keep a population of non-resistant bugs alive and breeding.
Think of GMO as small pox.
People in the middle ages who had the ccr5 gene mutation had a natural resistance to small pox. Those genes were passed on so now people with the gene have resistance to HIV.
Bugs with certain genetic traits that allowed them to resist the GMO crop lives and passed those genes down. The bugs with no resistance died.
Farmers were supposed to plant non-GMO crops, this was like someone in Scotland never being exposed to small pox. That person had kids and his genes survived.
We want those bug genes who are not resistant to GMO to get passed down.
We are trying to kill the bugs, but the bugs are adapting. Kinda like how small pox tried to kill our ancestors, but the genes of our ancestors adapted.
Small pox and bubonic plague killed millions, but there was always a certain population that was resistant. That resistance was passed down. Just like what the bugs are doing.
