Sorry that was a bit hyperbole it would never be an all or nothing. You’d always have limited grass fed animal husbandry for milk and cheese. But my thought was that there should be some sort of rewilding effort for cows or Buffaloes or whatever their wild form even is or was in Europe.
And I was thinking in the way of harm reduction which is a tactic for drug. You won’t convince a majority of people to not want meant so the demand will be there. So practically artificial meat is the only way.
