Is there a reason you and some many commenters here are concerned about food security? Has this became a nativist rallying cry of some sort? Because by all fact-based accounts there is no problem with food production in Europe.
And if food security became an issue we could reverse policies.
This won't be implemented overnight.
We could also just make less bio fuel, or eat more plants less animals, etc.
Lots of options, sure we need some food security, but there are limits to how much overproduction we need.
There have been many famines in Europe throughout the past few centuries. Perhaps we're now at the end of history and nothing like that will ever happen again but since countries aren't willing to take that bet.
