It's a crazy world for the globalists, I don't understand how they think they can get away with these comments. As of right now, Britian is buying food from the rest of the EU due to it being profitable for the EU to sell it there -- and it's a profitable business relationship for the British to buy this. They're able to grow their own food, it's not like their a nation that's going to starve out due to this.
Nobody has to starve in a modern society. That's exaggeration, for sure. Just the economical impact will be cruel. If UK citizens really have to start fishing fishies for themselfes, growing grocery inside their gardens ... they will have to face constant mocking from 48% of all of their neighboors.
That will be the real cruel issue.
Besides that you cannot be some financial superpower by separating yourselfes from trade, raising borders and barriers. Just doen'st sum up, that approach. Deal with it.
