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.
That spirit of self-sufficiency runs through the history of American food culture. Lydia Maria Child’s 1829 manual The Frugal Housewife, one of the first American cookbooks ever published, instructed women to contribute to their family’s finances by making sure no scrap of food was wasted: “Nothing should be thrown away so long as it is possible to make any use of it, however trifling that use may be.” The Church of Jesus Christ of Latter-Day Saints* encourages members to keep a three-month food supply on hand at all times, and even sells dehydrated food products on its official website. This Mormon connection may be why Utah is such a freeze-dried food hub: Of 21 freeze-dried food companies I counted online, 16 were from the state, and Bedford told me she first learned about long-term food storage by reading blogs by Mormon women.
Followers of James Wesley Rawles often prepare for multiple scenarios with fortified and well-equipped rural survival retreats. This group anticipates a near-term crisis and seek to be well-armed as well as ready to dispense charity in the event of a disaster. Most take a "deep larder" approach and store food to last years, and a central tenet is geographic seclusion in the northern US intermountain region. They emphasize practical self-sufficiency and homesteading skills.
Then a woman wearing a fanny pack, Marcia Brumfield, reads aloud the day’s headlines from decidedly non-MSM sources. The United Nations is taking over the Chicago Police Department to perform population control, evidently. A train crash killed 70 in Seattle. (The figure at the time was actually seven.) It’s implied that Antifa is to blame. “They want a war,” Brumfield says. “They’re the elites, and they want population control.” Last on the docket, “they” are using direct energy weapons to start wildfires in California. It’s unclear who “they” are, but apparently, they’re after the fruits and nuts.
How many wealthy Americans are really making preparations for a catastrophe? It’s hard to know exactly; a lot of people don’t like to talk about it. (“Anonymity is priceless,” one hedge-fund manager told me, declining an interview.) Sometimes the topic emerges in unexpected ways. Reid Hoffman, the co-founder of LinkedIn and a prominent investor, recalls telling a friend that he was thinking of visiting New Zealand. “Oh, are you going to get apocalypse insurance?” the friend asked. “I’m, like, Huh?” Hoffman told me. New Zealand, he discovered, is a favored refuge in the event of a cataclysm. Hoffman said, “Saying you’re ‘buying a house in New Zealand’ is kind of a wink, wink, say no more. Once you’ve done the Masonic handshake, they’ll be, like, ‘Oh, you know, I have a broker who sells old ICBM silos, and they’re nuclear-hardened, and they kind of look like they would be interesting to live in.’ ”
Preparing for an emergency is different for every family. Naturally, buying nutrient-rich foods and having ways to store and purify water is the first step for everyone. After that first step, deciding what type of supplies and gear to focus on is a personal journey depending on your preparedness goals. Think of your emergency supply as an investment in the health and safety of your family during a crisis.
For now, he broadcasts Monday through Friday, 9 to 11 a.m., and Finelli invites “instructors”—doctors, dentists, survivalists, a man who carries no identification, an Australian woman who talks about seceding from the government—anyone who has something relevant to preparedness. To Finelli, there’s little that isn’t relevant. He doesn’t sell merchandise or accept donations, as fellow GCN hosts such as Jones do.
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.
