Hmm.. wouldn't all those plants be fed to animals? GMO in EU is only allowed as animal feed. Those plants get treated with the same pesticides (if not stronger)

Hmm.. wouldn't all those plants be fed to animals? GMO in EU is only allowed as animal feed. Those plants get treated with the same pesticides (if not stronger), but now a cow eats through tons of grains while you would never eat that much food in a lifetime. Then, the cow's body bioaccumulates the pesticides and then you keep dosing yourself with larger amounts than if you just ate the plants directly?
