>>1467949If you have shelter, you won't need fire. Remember shelter can be a debris shelter or a resort house insulated with aerogel-based insulation. Regardless, the shelter's #1 purpose is to protect you from the environment. If the environment is, "fucking cold," then your shelter needs to reflect that. Food and water don't need to be heated or cooked when you can simply have potable water already and food that never needs cooking.
