I think the proposition that NOT using GMOs risks global catastrophe might have more odds in its favor than using GMOs.
Bananas, citrus, chocolate, coffee are all threatened by pathogens or climate change. There are some credible pathogen threats to wheat as well.
In the case of citrus, the ONLY (**ONLY**) resistant variety to citrus greening disease, out of ALL the citrus varieties on the plant, is a GMO variety that has genes from spinach spliced in.
So we have a case of, worldwide collapse of citrus production, OR GMO citrus.
I think I'll take the GMO citrus, thank you very much. If I were a Florida planter, and I weren't worried about anti-GMO hysteria, I'd be replacing my citrus orchards (as they die) with GMO plants.
As I referred to above, similar threats are either now or are poised to decimate bananas, coffee, chocolate, and wheat, though I'm not so sure that the naturally resistant variety situation is so dire in those cases.
