We in Europe have good reasons, in fact very good reasons to reject GMOs. Its a very powerful tool, very poorly tested, side effects on whole ecosystem not tested at all (aka if you don't brag about safety in ads, it means there is nothing to brag about).

They often come from most amoral companies in the world, ie Monsanto which clearly don't care about human health and life, only profits at all costs. They are often pushed by political means (ie US business folks coming ie to UK to lobby for lowering food safety standards compared to those from EU right after it was clear Brexit is happening).

You want to solve world hunger and feed those poorest and most unfortunate that would otherwise die? Sure go ahead, but at least attempt to be moral and show some serious research into collateral damage. You try to push that cheap untested crap on one of the world's most rich and free regions? Well clearly your chops are not good enough right now.
