Farming subsidies etc are the reality in high-income countries like UE or USA. But UE doesn't really *need* GMO because it can produce huge amounts of cheap food already.
GMO is needed in the first place by low-income countries in Africa and Asia, which still experience famines or vitamin deficits in 21st century! And here you have Greenpeace "heroically" destroying Golden Rice or Bt brinjal crops for the sake of... "purity" and fanatics like Vandana Shiva.
> we've literally been doing this for thousands of years
Because we have. The whole environmental narrative about what is "natural" is completely ahistoric.
Do you know what is truly "natural"? Well, just go out to a meadow and try to find anything edible there. Maybe a frog, maybe some grass, maybe some tiny fruits.
But this is how homo sapiens lived for the last 1.8 million years! This occasionally comes back in various "paleo" diets.
