They will have to ban all pesticides and GMOs soon or there will be no food.
You stated
as corn was one of the first to become totally GMO due to cross pollination afaik
There are many corn varieties that are still heirloom. https://returntonow.net/2021/11/07/mexico-replaces-16-million-tons-of-gmo-corn-with-native-varieties/
Take a look at this beautiful corn seed you can buy https://www.marysheirloomseeds.com/collections/heirloom-corn
Wow I will have to buy some of this beautiful heirloom corn seed.
You might be right, but I see zero moves to achieve that.
There are corn seeds sold as heirloom and I imagine that some have survived - but in terms of commercial crops, I am informed that even the non GMO ones are now mostly affected by GMO genetics.
