This is very interesting question to pose - not only on your side of the world... but everywhere! My brother in London has been telling us for YEARS to start stockpiling canned foods and dry goods that keep, for MULTIPLE reasons locally and politically related, climate related etc. - but what happens, nobody does it. I think I may just take heed of your reminder and his advice. Human beings are all too quick to shrug things off and then they stand with a loss for words when things do in fact fall to pieces and reserves as required.
