We might be OK with nice thick wool jumpers though as I think we still have a lot of sheep. And sheep don't compete for food with us.
But bastard moths compete for wool with us!
At the start of ww2 we had I think 24 million sheep not competing for rationed food, and 4 million pigs that were. In Germany it was almost the exact opposite as they loved pig, so 24 million pigs and 4 mill sheep. Didn't help their rationing.
Not that I'm suggesting we'll need rationing again. Just that I like fun facts.
