Jennifer had already taken the necessary precautions the night Hurricane Maria came barreling through the Caribbean. The 46-year-old stay-at-home mom, who lives on two acres of land with her husband and four children atop a mountain in Manati, Puerto Rico, was ready to make use of the filter she’d purchased for sterilizing rainwater in case the taps ran dry. And she didn’t have to worry about food, because her pantry was already stocked with two-and-a-half years’ worth: giant buckets of lentils, flour, and rice; shelves lined with mason jars of fruits and vegetables she had grown and canned herself.
But of the many women I spoke to for this story, none view their lifestyle as non-collaborative. For Andrea Chymiy, a family doctor who lives on an island several miles from mainland Washington and runs a blog called Lefty Prepper Mom, learning about emergency preparedness and writing about prepping is part of a wider commitment to community service: providing others with the emergency first-aid skills and food storage know-how to fend for themselves in the event of an earthquake or other natural calamity.
In his book titled Essays, “Self-Reliance” follows “History” so that a balanced and self-contained unit can be created out of these two. Abounding with short aphorisms, the essay begins with an admonition to believe in the true self, which is considered in essence identical with the Universal Spirit: “Trust thyself: every heart vibrates to that iron string.” Emerson then holds infancy, which is favorably contrasted with adulthood, as a model for one to follow in the cultivation of a spirit of independence or nonconformity. His metaphorical use of a babe as a model of nonconformity is a radical twist of Christ’s elevation of it as an emblem of total dependence on God.
For nonconformity the world whips you with its displeasure. And therefore a man must know how to estimate a sour face. The by-standers look askance on him in the public street or in the friend's parlour. If this aversation had its origin in contempt and resistance like his own, he might well go home with a sad countenance; but the sour faces of the multitude, like their sweet faces, have no deep cause, but are put on and off as the wind blows and a newspaper directs. Yet is the discontent of the multitude more formidable than that of the senate and the college. It is easy enough for a firm man who knows the world to brook the rage of the cultivated classes. Their rage is decorous and prudent, for they are timid as being very vulnerable themselves. But when to their feminine rage the indignation of the people is added, when the ignorant and the poor are aroused, when the unintelligent brute force that lies at the bottom of society is made to growl and mow, it needs the habit of magnanimity and religion to treat it godlike as a trifle of no concernment.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
I suppose no man can violate his nature. All the sallies of his will are rounded in by the law of his being, as the inequalities of Andes and Himmaleh are insignificant in the curve of the sphere. Nor does it matter how you gauge and try him. A character is like an acrostic or Alexandrian stanza; — read it forward, backward, or across, it still spells the same thing. In this pleasing, contrite wood-life which God allows me, let me record day by day my honest thought without prospect or retrospect, and, I cannot doubt, it will be found symmetrical, though I mean it not, and see it not. My book should smell of pines and resound with the hum of insects. The swallow over my window should interweave that thread or straw he carries in his bill into my web also. We pass for what we are. Character teaches above our wills. Men imagine that they communicate their virtue or vice only by overt actions, and do not see that virtue or vice emit a breath every moment.
This kind of focus on the problem at hand is used by some of the best sports coaches in the world. Bill Walsh’s book The Score Will Take Care of Itself dedicates its title to the idea. Phil Jackson describes in Eleven Rings how he’d make his team focus all their energies on the current practice or current game and not on any championships. He even had his team, some of the best athletes in history, meditate in order to do this more effectively. The best way to a better future is focusing on the current step, which is only available in the present moment.
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.
Prior to Y2K, Preppers were highly focused on Cold War concerns and how to survive a Nuclear War. They used the term Survivalist to describe themselves. Some of their thought leaders included Howard Ruff, Kurt Saxon, Mel Tappan, Jeff Cooper and Ragnar Benson. There was a lot of discussion of underground bunkers, food storage and water purification.
Bogwalker, a Washington state native with a degree in ecological agriculture who built much of the compound with her own two hands, says she considers herself much more of a homesteader than a prepper. Still, she says she’s seen many women who identify as preppers take her courses. “I think no matter where you are on the spectrum with your definition of prepper, a lot of the people, probably 65 percent of my students, are curious about the future,” Bogwalker says.
“Methamphetamine is 95 percent addictive the first time you try it,” Pense likes to say. “My gardening system is 100 percent addictive.” Pense gardened all his life, but when he moved to Springfield, the rocky Ozarks soil stumped him. “I discovered that you can buy land here and not get any dirt with it,” he says. So he experimented with gardening out of an 8-by-8 foot sandbox, mixing sand, compost and fertilizer. The plants grew, and with them, the idea for a raised-bed gardening system complete with top-notch soil that would enable people around the world to grow their own food.
In fact, one of the subjects specifically told Mills that "it’s not like on [National Geographic’s] Doomsday Preppers." They weren't preparing for the total collapse of society. They were getting ready to deal with a local collapse of services that might last a few months. It's less Armageddon and more Hurricane Irma—which hadn't hit yet while Mills was doing his interviews but has since suggested that preparing for a couple of months without key services may be badly underestimating needs. Prepper supplies would typically be enough to only hold out that long, and Mills said they often referred to these caches as "more than they'd ever need."
Action is a part of self-reliance, but so is introspection, else how will you know what action to take? We’ve got to remain fixed on our own path, and can’t know what that path is unless we’re tuned into our true wants and desires, and are able to admit that those aims are valid — even if they’re not connected to the kind of status markers of which society typically approves.
“There is a time in every man’s education when he arrives at the conviction that envy is ignorance; that imitation is suicide; that he must take himself for better, for worse as his portion; that though the wide universe is full of good, no kernel of nourishing corn can come to him but through his toil bestowed on that plot of ground which is given to him to till. The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.”
In his professional opinion, the next big development in prepping will be the arrival of entrepreneurial capitalists, and this made me think of Fabian Illanes and Roman Zrazhevskiy, two men in their 20s I met at the show-and-tell. Former classmates at George H. Hewlett High School on Long Island, Mr. Illanes and Mr. Zrazhevskiy have been prepping since their teens and recently created Readytogosurvival.com, a Prepper Web site that sells prepacked bug-out bags with paramilitary names like the Tactical Traveler ($439.99) and the Covert Defender ($629.99). They told me that they had been visiting Prepper meetings across the New York region in order “to discover their customers.”
In the early ’80s on a job for the State Department to reinforce U.S. embassies and consulates following the 1983 Beirut barracks bombings, Pense says he and other government contractors around the U.S. converged on CIA headquarters at Langley, Virginia. The consortium of engineers traded notes and decided that the U.S. power grid was vulnerable. Inadequate, Pense says, compared to everything that’s been hung on it, and that was three decades ago. Three high-altitude electromagnetic pulses (EMPs) could take the whole thing down. Like New York City’s 1977 blackout, looting and pillaging would rule the streets, and that’s if they can get the lights back on quickly enough—if the power stays off for too long, order is lost forever.
Preparedness refers to a very concrete research-based set of actions that are taken as precautionary measures in the face of potential disasters. These actions can include both physical preparations (such as emergency supplies depots, adapting buildings to survive earthquakes and so on) and trainings for emergency action. Preparedness is an important quality in achieving goals and in avoiding and mitigating negative outcomes. There are different types of preparedness, such as public health preparedness and local emergency preparedness or snow preparedness (i.e.: Snow Preparedness Teams - SPT), but probably the most developed type is "Disaster Preparedness", defined by the UN as involving "forecasting and taking precautionary measures prior to an imminent threat when advance warnings are possible". This includes not only natural disasters, but all kinds of severe damage caused in a relatively short period, including warfare. Preparedness is a major phase of emergency management, and is particularly valued in areas of competition such as sport and military science.
