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.
After three days eating very little vegetable matter, I was thrilled to dig into Thrive Life’s Tuscan Quinoa Bowl, which included a ratatouille-like sauté combining asparagus, zucchini, and diced tomatoes. The cooking process felt kind of like a science experiment— you fry dehydrated garlic bits in oil, then pour in the dehydrated vegetables and seasoning along with a cup of water—but the result actually tasted like something I might cook at home, minus the strangely firm consistency of the vegetables. The following night, I prepared a Chicken Cranberry Pot Pie, rolling out the dough for the pastry, cooking the filling in a slow cooker, and carefully sealing the pie with the prongs of a fork.
According to Hobel, shelter is your first priority. Lay down cardboard and other materials to insulate yourself from the ground. (Even in summer, the ground can have temperatures that lead to hypothermic conditions.) Use tarps, blankets, pillows—whatever you can find—to build the shelter on that layer. It should be as low to the ground as possible, and you shouldn’t be able to sit up when you’re inside, Hobel says. Other than the airflow you need to breathe, block all openings to keep cold air from coming in. It’s a matter of conserving heat. A lot of people don’t realize that their bodies are heat sources, Hobel says. You’re almost 100 degrees. Trap that heat around you instead of letting it rise in a tall shelter, and you won’t need a fire to stay warm.
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.
I’m not going to try to candy coat this one. If you need this product, you’re in the middle of a terrorist attack or an act of war using a chemical warfare agent (CWA). The people around you will be dying. You’re going to die, too, if you breathe in these chemicals. But if you only have skin contact with these lethal substances, and you have a decontaminant at hand – you can neutralize them. Let that sink in for a moment. If you only come into contact with a chemical weapon on your skin, there is a product that will counteract most toxins. Now, this isn’t exactly a new product. In fact the company has been making this product for many years, and a friend of mine has successfully used it in “live agent” military training. The part that’s new is that this product is now available to civilians. RSDL is the only decontaminant cleared by the U.S. Food and Drug Administration to remove or neutralize chemical warfare agents such as tabun, sarin, soman, cyclohexyl sarin, VR, VX, mustard gas and T-2 toxin. It’s a simple little packet of lotion-like neutralizer. Each kit comes with instructions and a training product, so you can get a feel for it through realistic practice. It also comes with a packet of decontaminant for one person, which removes the chemical agent from the skin in a single step.
He ushered me through, and, in the darkness, I could see the outline of a vast concrete dome, with a metal blast door partly ajar. I was greeted by Larry Hall, the C.E.O. of the Survival Condo Project, a fifteen-story luxury apartment complex built in an underground Atlas missile silo. The facility housed a nuclear warhead from 1961 to 1965, when it was decommissioned. At a site conceived for the Soviet nuclear threat, Hall has erected a defense against the fears of a new era. “It’s true relaxation for the ultra-wealthy,” he said. “They can come out here, they know there are armed guards outside. The kids can run around.”
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
Nail your studs together in lengthwise pairs at a 90-degree angle to form braces. This makes them stronger. Then run three or four braces horizontally across every door, hammering the nails from above and below directly into the frame at a 45-degree angle. If you drive them straight in, they're easier to pop out when somebody kicks the door. Use more braces to secure the drywall over the windows. Try to use longer nails and leave a couple inches of each nailhead sticking out for easy removal. — Clint Carter
