Would growing wild edible plants be useful if worried about gmos?

I have a better idea: If you're concerned about GMO foods (and I do not know any scientist who avoids them, though there are physicians here who do), you are welcome to purchase food that's labeled as GMO-free. Stay health-conscious, but to make a huge, time-comsuming, costly venture like what you propose just because you are 'worried' would enslave you to every other fearmonger as well. Best wishes.
