Our situation is most precarious. We sit on the eve of a number of cataclysms that may do untold damage individually, yet refuse to acknowledge the existence of any. Many environments have started their inexorable death; nuclear sabres are being rattled, but this time the sabreurs are unlikely to sheath; a new influenza is starting to claim lives; economies are being built ever higher, even as their foundations crumble; and a few of us, amateur and professional astronomers, have been monitoring several relatively nearby stars, one in particular that although cannot destroy the world, would destroy the ozone layer for a time.
Which leaves planning a problem. It is impossible to run for the hills, to wait for the inevitable - proper preparation takes time and resources, resources take money - and money means the need to be employed. As much as some may eschew attachment to society at large, their views are isolationistic - they believe they can protect themselves and their immediately families by removing themselves. Some of their attitudes are useful - they choose to move away from cities, learn to become self sufficient; some attitudes are counterproductive.
Take the things we have gotten use to - communication, health. Ask a "regular" survivalist what preparations that they have made, they will say they have a few tools, perhaps a firearm or two (and some ammunition), perhaps a shelter, a water purifier, two years of food. Yet tools break or grow blunt, firearms wear out, ammunition gets used up, water purifiers lose effectiveness, food runs out, gets eaten, or goes rotten.
A shelter, on the other hand, does do much good, if it's constructed well. But metal corrodes, concrete falls apart. I have seen some options made of plastics or fibreglass which might be usable. Of course, a good underground shelters need to be exactly that - underground - not the work for a single man with a shovel.
Even then, you can only do so much preparation, only store so much food and equipment. There comes a time where you have to get your hands dirty.
So, I spend my spare time learning to garden, nearly all food plants. Some fruit and vegetable staples, many food trees - natives and exotics. Pawpaws, macadamias, figs, olives, black sapote, many more - or at least will be when they grow tall enough to produce fruit. Hopefully, we will have time before their produce will be needed. Well known grains - wheat, oats, barley, and rye - known fruits and vegetables - tomato, pumpkin, beans - and a few more exotic things foods.
Seed stores are another misconception. Anyone can pick up a packet of seeds from a shop; knowing how to look after the growing plants, knowing that seeds loose viability over a few years, knowing that the next generation of seed will be viable - that is another matter entirely. Too many seeds are hybrids, they will produce the food, but not the new seed to continue to produce next year's crop. People relying on a few packets of seeds to see them into the future build their house upon the sand, oblivious to the starvation that awaits them. Combine that with the risks of crop failure - particularly at the hands of a beginning gardener...
Chaotic death will not be the exclusive domain of those to fall first - those who don't learn will join them. Those that don't learn the past, those that don't take the time to learn while there still is time, and those who don't learn at least some of the things that will be needed soon, all will become dust.
