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.
100 years ago we discovered that some chemical substances accelerate DNA changes in plants (and in humans, where we call them carcinogens"). That's great thing, as random mutations are slow - so we started to chemically induce mutations in thousands of seeds, breed them and select the ones with desired mutations.
