I don't know a few victory gardens and vertical farms could stretch things out for quite a ways before we need to fully switch to GMO in order to survive.
For veg, sure. I'm all for it. Great way to teach and learn, as well. For example, squirrels aren't so cute after they destroy you entire tomato crop... lil' fuckers.
But grain is such a process and such an amazing supply chain. I don't see that being replicated.
