Ok folks - so you don't store food, you don't have an emergency plan, you don't have a back-up arrangement for friends and relatives, you don't believe peak oil is coming (never mind those "temporary" gas prices over $3.00), and you think that those of us who worry about that sort of thing are out of our minds. Sure, you believe we should all be conserving more energy, but not in any way that actually *hurts*...
And you are right, there is something strange, surrounded by so very much plenty, about fixating on poverty and loss. But without that fixation (even with that fixation, but you can lower the risk more than a bit) we are all a few steps away from hunger, dehydration, being a refugee. At least, Katrina should point out that message.
Think about those people whose infants and elders died of dehydration. A portable, high quality water filter would have saved some formula fed infants' lives (an actual policy in which we *truly* encouraged nursing and actually worked to make it possible for all mothers would have done much, much more!) and kept people's elderly parents alive. For those trapped in their homes for an extended period, a supply of stored water, stored food and medical supplies could save lives. A way of doing most things without electricity could mean a quality of life not available to others, the difference between a frightening adventure and a terrifying ordeal.
For those who have had family descend upon them, and fear the economic consequences, stored food and other materials could mean the difference between being able to offer help with an open hand and struggling to feed an expanded family.
Do it. Do it now. Plan for a future less promising than right this second. Plan for the day that you need to leave your house at a dead run, and can only take what you can cram in the car. Plan for the day that you can't get to the grocery store, and the water stops coming out of the tap, and you have children to feed. Plan for the day that hard times hit and you have no job, no money. Plan for the day your entire extended family has to come live with you. Stockpile food. Pack a bug-out bag (a short term supply of necessities). Store some extra blankets and pillows, some empty soda bottles full of water. Put up the rainbarrel and buy that water filter. You can manage it, and if you never need it, you can tell everyone that the wacko on the blog made you do it, and laugh at me.
