For global catastrophic risks the costs of food storage become impractical for most of the population [52] and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.[53]

Some evangelical Christians hold to an interpretation of Bible prophecy known as the post-tribulation rapture, in which the world will have to go through a seven-year period of war and global dictatorship known as the "Great Tribulation". Jim McKeever helped popularize survival preparations among this branch of evangelical Christians with his 1978 book Christians Will Go Through the Tribulation, and How To Prepare For It.

Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.
This group consists of people who live in tornado, hurricane, flood, wildfire, earthquake or heavy snowfall-prone areas and want to be prepared for possible emergencies.[33] They invest in material for fortifying structures and tools for rebuilding and constructing temporary shelters. While assuming the long-term continuity of society, some may have invested in a custom-built shelter, food, water, medicine, and enough supplies to get by until contact with the rest of the world resumes following a natural emergency.[30]
In 1980, John Pugsley published the book The Alpha Strategy. It was on The New York Times Best Seller list for nine weeks in 1981.[10][11] After 28 years in circulation, The Alpha Strategy remains popular with survivalists, and is considered a standard reference on stocking food and household supplies as a hedge against inflation and future shortages.[12][13]

The Missouri Information Analysis Center (MIAC) issued on February 20, 2009 a report intended for law enforcement personnel only entitled "The Modern Militia Movement," which described common symbols and media, including political bumper stickers, associated with militia members and domestic terrorists. The report appeared March 13, 2009 on WikiLeaks[87] and a controversy ensued. It was claimed that the report was derived purely from publicly available trend data on militias.[88] However, because the report included political profiling, on March 23, 2009 an apology letter was issued, explaining that the report would be edited to remove the inclusion of certain components.[89] On March 25, 2009 MIAC was ordered to cease distribution of the report.[90]
Preparing for catastrophic or short range survival is extremely personal and most of us keep it tight to our chest. I think PowderKeg says it best – Invisible and then Nuttus who knows that not all of us are the same skill or wherewithal stage, yet as a TEAM we shore up each others weaknesses, learn off each others strengths and it is a continual building process going forward.
Survivalists maintain their group identity by using specialized terminology not generally understood outside their circles. They often use military acronyms such as OPSEC and SOP, as well as terminology common among adherents to gun culture or the peak oil scenario. They also use terms that are unique to their own survivalist groups; common acronyms include:
A: There’s a lot of overlap between the above question and this one but basically once you have your survival gear separated into different categories you’ll want to distribute it in the exterior pockets of the backpack where it can be easily accessed in an emergency. The MOLLE survival gear system devised by the armed forces for combat troops takes a modular approach to organization that’s also extremely flexible and allows you to configure your supply load in a way that makes the most sense for you. Rows of nylon webbing are distributed across a vest that’s worn under the backpack. You’re then able to attach various MOLLE compatible accessories and pouches – in this case containing your survival gear – to the vest. Additional pouches can be attached to webbing on the exterior of the backpack as well.
Here are just a few choice gems from The Prepper Journal's 11 Ways A Condom Can Save Your Life: starting fires (they're great at protecting tinder from moisture), hunting for food (sexiest slingshot ever!), and transporting up to two liters of water (yes, rule 34 applies; no, we won't provide the link). They also make serviceable stand-ins for rubber gloves and can be used to protect the muzzle of your other essential survival tool (killing it right now).
Paracord is one of the most versatile pieces of survival gear you can carry. It has applications as diverse as helping you set up a makeshift tent to creating a clothesline for drying wet clothes to establishing a perimeter around your campsite that will warn you of the approach of curious or hungry mammals. On top of that you can use it to transcend physical obstacles like small cliffs you might encounter as you attempt to reach civilization. It’s essential survival gear for the person that likes to be prepared for any eventuality.
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.

OK. Great. You've stockpiled for the end of the world, you quack. The chances of the world ending are smaller than ... holy crap, what the hell is a supervolcano? See why we're all doomed in 5 Ways The World Could End That You'd Never See Coming. And if that's not enough to get you to build your own bunker, check out 6 Tiny Mistakes That Almost Ended The World. Really, the planet almost ended due to a blown fuse? Come on humanity, let's get it together.
Not taking a cheap shot at the author, but wouldn’t the author fall into 1 or 2 of these categories? I think the human character of every individual harbors a little bit of all or several of these. Most, if not 100% of anyone prepping has in their specific individual plan – their family members. Each family member brings their own set of considerations (assets & liabilities) to the table. Are we to avoid/cast out these family members due to their nonconforming attributes? This eludes me to one of the categories you left out – The resistant/reluctant prepper. Because if you have a family there’s a strong chance you will have one of these, but they too come around in time.
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.
With the world seeming to become a more volatile and dangerous place with every encroaching year, it can be hard to know exactly where you can feel safe. The modern media is overloaded with stories about violence, crime, and sensational pieces on the worst people in our society. But there have to be some places within the United States where the chances of anything like that happening to you is next to impossible, right?
