Okay, so pollen from Bt corn is lethal to monarch butterfly caterpillars. Meanwhile, pesticides are killing off 75% of all flying insects. I like monarchs, but if I had to choose between a world with no monarchs, and a world with no monarchs and also just 25% of the flying insect biomass we had 30 years ago and also fewer birds and everything else that consumes insects and all of the beneficial pollination that those 75% of insects would have accounted for ... well, that seems like a pretty easy choice to me. Gene editing would also provide an avenue for a different approach here, where the crop could be made resistant to its costliest pests without harming monarchs. Good luck doing that through cross-breeding.
