When you go back to the last depressing days when we were in a survival mode, the last one the Y2K of course, before the 1970s, what had happened was you only saw this one element of survivalist, you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This is a very different one from that: you're seeing average people taking smart moves and moving in intelligent directions to prepare for the worst. (...) So survivalism in every way possible. Growing your own, self-sustaining, doing as much as you can to make it as best as you can on your own and it can happen in urban area, sub-urban area or the ex-urbans. And it also means becoming more and more tightly committed to your neighbors, your neighborhood, working together and understanding that we're all in this together and that when we help each other out that's going to be the best way forward.
Adherents of the back-to-the-land movement inspired by Helen and Scott Nearing, sporadically popular in the United States in the 1930s and 1970s (exemplified by The Mother Earth News magazine), share many of the same interests in self-sufficiency and preparedness. Back-to-the-landers differ from most survivalists in that they have a greater interest in ecology and counterculture. Despite these differences, The Mother Earth News was widely read by survivalists as well as back-to-the-landers during that magazine's early years, and there was some overlap between the two movements.
Followers of James Wesley Rawles[43] often prepare for multiple scenarios with fortified and well-equipped rural survival retreats.[44] This group anticipates a near-term crisis and seek to be well-armed as well as ready to dispense charity in the event of a disaster.[41] Most take a "deep larder" approach and store food to last years, and a central tenet is geographic seclusion in the northern US intermountain region.[45] They emphasize practical self-sufficiency and homesteading skills.[45]
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear.[30] The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. [32]
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
