If all those measures are necessary then they will happen, or I guess we die trying, but you're right they are a much harder conversation.

The question of food is a big one and you're right it's going to probably be the hardest to swallow. The key will probably be in the economics of it. Ending factory farming as a viable business model by appropriate taxation for the land use and emissions will send meat prices through the roof, but that's kind of where they have to be. People tend to be more willing to accept the idea of 'I can no longer afford this thing' rather than 'this thing is banned'.

The benefit is that it will actually be easier to feed everybody in the world if we're not also trying to feed billions of livestock animals as well. Big efficiency saving.
