It's a joke, but I do have questions in general about "Certified Non-GMO" versus "Modern day bananas, corn and tomatoes look nothing like they did 400 years ago". There are some types of genetic modifications that are considered "natural" and "OK" and somehow there are others that are "artificial" and "scary", but damned if I know which are which.
To play devil's advocate to myself and possibly answer my own question: I imagine there are ecological effects of GMO (some of your corn SHOULD get killed by insects). Not to mention the fact that GMO seeds are probably mostly sold by god-awful Monsanto.
“No GMO” labeling isn’t because of any of those issues though; it’s just marketing to Green Meme people, upper class Whole Foods shoppers who are big into naturalistic fallacies.
Maybe someone with an agricultural background would have an easier time researching this, but:
"mostly" Monsanto? Or is that just an older, famous example? Lots of companies sell seeds in mass quantities -- are you saying none of them sell GMO seeds?
