Number 1 -- Why make it (survival) harder on ourselves? Why move somewhere where the weather can kill us? I hate to be cold, and if we moved to all those northern states, we'd spend all our time just trying to keep from freezing most of the year. So move where it's warmer. I live in Virginia right now, it's not too bad.
Number 2 -- Do you know how much time you'd be spending hunting and preparing and storing animals? Well, I'm here to tell you I've been a Vegetarian Raw Foodist for 7 years and I never felt better. Never get sick, no colds or flus or viruses, nothing. And if little me can thrive on raw food, anybody can. I do eat raw goat's milk sometimes, and I'm not sure if we need dairy and eggs or not, but that's a lot easier than 'hunting', cooking and eating dead animals.
Leave the food situation to me and we'll all be fine.
