For global catastrophic risks the costs of food storage become impractical for most of the population  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.
Braxton and Kara Southwick from Utah offer a tour of a declassified bunker. They will star in the upcoming National Geographic Channel show 'Doomsday Preppers,' featuring Americans stockpiling for the end of the world. NGC conducted an online survey with 1,040 people to find out how they would spend their final days. Here are some of the results. By Tim Loehrke, USA TODAY
This is a very interesting premise, but the episodes get tiresome as the format is increasingly repetitive. Also, some really obvious mistakes that the preppers make are sometimes ignored: shelves full of glass bottles at eye level (no lip on shelves) in preparation for a major earthquake? Also, the one issue preparation (climate change, economic collapse, Yellowstone blowing up, etc.) seems tunnel-visioned, but apparently the shows' writers need that statement as a justification for their script. The fact is that most of the preppers and the needed preparations that each makes are very much the same in the outcomes they're working toward.
ARE YOU PREPARED? The end of the world didn’t come for Judgement Day followers who expected the rapture in May 2011. But who are these people who continuously fear the end of the world and obsessively prepare themselves and their loved ones for the worst? Meet "preppers" including one man who built an underground bunker where he and his family can retreat during a nuclear attack.
Articles on the subject appeared in small-distribution libertarian publications such as The Innovator and Atlantis Quarterly. It was during this period that Robert D. Kephart began publishing Inflation Survival Letter (later renamed Personal Finance). For several years the newsletter included a continuing section on personal preparedness written by Stephens. It promoted expensive seminars around the US on similar cautionary topics. Stephens participated, along with James McKeever and other defensive investing, "hard money" advocates.
Hide from trackers in the forest with a shallow trench dug in just minutes ... a last resort weapon when you've run out of bullets ... Here are several things you can do with an Army shovel and why modern day militaries that include Russian commandos train soldiers in the effective use of an "entrenching tool." How to Evade and Escape Tracking Dogs
“And carnal nature said, ‘I’ve got eight shots, they’re not by their weapons, I’m going to kill every damn one of them.’ And then I saw the women. Hollow-faced, it looked like you had draped skeletons with cloth. Horrible, and the children were the same way. Far, far worse than anything I had ever imagined. I could see it, I could smell it, I could taste it, I could feel it. It was real. It’s going to be an experience you don’t want to go through.”—A dream Len Pense had, circa Fall 2017.
If you’re ordeal is an extended one you can lash the Ultimate Pro Knife to a small branch to create a spear for catching fish or small mammals. The pommel at the butt end can be used to hammer tent stakes and that little thing hanging from the lanyard cord is a powerful emergency whistle that can take over emergency signaling duties from the tactical flashlight or your long range walkie talkies when the sun comes up. A top-notch knife like this is essential survival gear.
Webb's includes an aspirin- and ibuprofen-filled pill bottle wrapped in duct tape and medical tape, a couple of gauze pads bound in a rubber band, and a standard gauze roll and a Kerlix gauze roll. It's enough gear to "stop a bleed and wrap it tight with the tape, or wrap a sprain and take the pain meds," he says. Webb packs it all in a Norelco shaver case.
“How do I tell Dr. Norman Shealy that he was voted out of the meetup?” Finelli asks, rhetorically. “So I told him on-air. I said, ‘Dr. Shealy, they had a vote, and you were voted to be barred from the meeting.’ And he kind of laughed, and I said don’t get all excited, they banned me, too.” He holds no grudges; he says he’s actually glad it happened. Now he knows how his students really felt.
Kevin lives in eastern Washington and is prepping his family for a volcanic eruption using multiple bug-out vehicles. We also meet Captain Bill Simpson, who has built a bunker sailboat, made mostly of iron so that he could retreat out to sea in case of a massive solar flare which could send an energy wave, in the form of an Electromagnetic Pulse (EMP) which could damage today's technology.
If the fire is around you and you can’t escape, you don’t have many options, says Shane Hobel of the Mountain Scout Survival School. If there’s a pool or a pond nearby, jump in and try to wait it out there. Otherwise, if you have time, dig a trench that’s two to three feet deep and long enough for you to lie in. Soak a blanket in water, wrap it around yourself, and lie down in the trench. It’s risky, but at least you’ll have a chance.
