Is there dinner?
Yes, we can prepare to fight off zombie attacks, build earth shelters in case we lose ours (although odds are most of us will move in with a friend or relative), learn how to handle background radiation – but the first tier problems most of us face – and the ones most people prepare for first, are the ones we’re familiar with – what will we eat? How will we cook it? How will the hungry kids get fed? How will we keep the food and water coming in a supply disruption, or when we’re too poor to buy it? It isn’t that no one needs a gun or potassium iodate – it is that generally speaking the first question you will encounter in most crises is “Is there dinner? Do I get any?”
