In his 2016 book, Can It! The Perils and Pleasures of Preserving Foods, Gary Allen, a food writer and adjunct professor at SUNY Empire State College, traces the evolution of food preservation as a source of culinary innovation. “The original food-preservation methods—like salting and drying and all that—actually turned the food into something else,” he told me over the phone. “Cabbage sauerkraut is not the same thing as cabbage. Wine is not the same thing as grape juice.”

At least in theory, the recipe for surviving civilizational collapse is simple: you need to get away from other people and become self-sufficient. It's fairly clear that deprived of their industrial backbone, most of our cities and suburbs wouldn't be able to support even a tiny fraction of their current population densities - and would become horrid death traps. Living off the grid shields you from all but the worst doomsday events.
They hate their lives and fantasize about a world where they could be a hero. Melvin from Accounting can’t wait for catastrophe so he can become Melvin the Survivor! He’s praying for a complete economic collapse so he can look his boss and say, “I made 40k a year, but now I’m the post-apocalyptic king! I have all the SpaghettiO’s and I won’t lower my drawbridge to give you any! Muhaha!”

This brings us to the "how". In most cases, the absolute minimum water intake is somewhere around one quart per person per day; but note that this assumes no weather extremes, no substantial exertion, and no immediate hygiene needs. When these assumptions hold true, storing about 1.5 to 2 gallons per household member - enough for perhaps up to a week - should provide a viable if modest buffer for short-term emergencies. Store-bought gallon jugs are pretty cheap, hassle-free, and easy to squeeze in just about anywhere; if you keep them away from sunlight and heat, they should last 5+ years before needing to be rotated or thrown out. Don't try to save a buck by reusing milk or juice jugs, though: they are almost impossible to clean properly and may end up supporting bacterial growth.
Folks without a car are at a marked disadvantage, but should still try to put together a 72-hour "bug out bag" - and ideally, keep it somewhere within a walking or biking distance of their home (say, at work or at a friend's place). It's best to keep it light; some cash, 2-4 quarts of water, a 3,600 kcal emergency ration, and a raincoat will be almost certainly more useful than a gun and a collection of throwing knives.

They have a great selection of food storage kits, from 72-hour emergency kits to the Deluxe 1 Year Kit. However, Augason's best offering is the incredible selection of individual ingredients. This includes dehydrated and freeze-dried vegetables and fruits, rice and grains, baking ingredients, powdered milk and eggs, freeze-dried yogurt, beans, gluten-free products.
In addition to such immediately necessary supplies, some prepper guides recommend purchasing sutures, along with tissue forceps and hemostatic clamps. Such equipment may be useful for neatly closing major wounds in situations where bandages won't do - but suturing correctly requires a fair amount of practice and know-how. For gnarly cuts, skin staplers or skin closure strips + benzoin swabs tend to involve less hassle - and are harder to mess up.
Thanks for the comment “Barn Cat”. I do agree that storing canned beans makes it much easier since they are already prepared. That would be a huge help when you need something to eat in a hurry. I am inclined to say that having both dried beans and canned beans would be ideal for food storage. Canned items typically do not last as long. Another fact is that you can also sprout dried beans and it increases the nutritional value. Wheat can also be sprouted, ground into flour to make bread and cooked to make a hot breakfast cereal. Wheat, if stored properly can be stored up to 25+ years. I personally like to have a variety my food storage.

In the 90s, it seemed that you couldn't go wrong by getting into professional journalism, opening a video rental store or an arcade, or selling calculators, encyclopedias, disposable cameras, answering machines, and audio CDs. We would be very naive to hope that the next twenty years will not bring similarly dramatic disruption to many of the seemingly cozy professions of today.
I asked Hoffman to estimate what share of fellow Silicon Valley billionaires have acquired some level of “apocalypse insurance,” in the form of a hideaway in the U.S. or abroad. “I would guess fifty-plus per cent,” he said, “but that’s parallel with the decision to buy a vacation home. Human motivation is complex, and I think people can say, ‘I now have a safety blanket for this thing that scares me.’ ” The fears vary, but many worry that, as artificial intelligence takes away a growing share of jobs, there will be a backlash against Silicon Valley, America’s second-highest concentration of wealth. (Southwestern Connecticut is first.) “I’ve heard this theme from a bunch of people,” Hoffman said. “Is the country going to turn against the wealthy? Is it going to turn against technological innovation? Is it going to turn into civil disorder?”

As for cars: there is no hope. Don't leave anything of substantial value in the vehicle, and if the car itself is expensive, have it insured against theft (setting your deductible to $1,000 or more keep the premiums low). Avoid tempting the thieves in any way: countless car windows have been smashed over a $5 bill and some coins left in the cup holder. Put spare change somewhere else.

Three hours after I arrived, Andrew: senses it’s time to wrap up, but not before breaking into one last story about the Bigfoot footprints he keeps in the back of his car. The prints were collected in Arkansas in 1956, he says, and they belong to an adult male, a juvenile female and an adult female. He says he himself came from the “drug scene hillbillies” and that his ancestors had six digits. 
Lightweight survival kits are generally seen as a backup means of survival; however, these can kits can be extensive, and have come to include tools that are generally found in larger kits as survival technology advances. Some examples of these tools are high power flashlights, rapid use saws, signal devices such as mini signal mirrors, and water purification methods.
You can survive several weeks without food, but you won't be having a very good time. Food is costly, its supply is fairly easily disrupted, and it's a resource that the government may be much less inclined to deliver to your doorstep when things go wrong. So, with a variety of reasonable scenarios to worry about - anything from natural disasters to economic downturns - it just makes sense to be able to feed yourself even if you can't buy groceries for a while.
