We get that creature comforts will be ever more important as the things that used to make us happy slowly break and crumble around us. But do you really want to put a ton of effort into opening a bakery when everything is going to shit? And we hate to be the bearers of bad news, but no amount of odor elimination is going to stop the uncivilized world from smelling really, really bad.
Huffman, who lives in San Francisco, has large blue eyes, thick, sandy hair, and an air of restless curiosity; at the University of Virginia, he was a competitive ballroom dancer, who hacked his roommate’s Web site as a prank. He is less focussed on a specific threat—a quake on the San Andreas, a pandemic, a dirty bomb—than he is on the aftermath, “the temporary collapse of our government and structures,” as he puts it. “I own a couple of motorcycles. I have a bunch of guns and ammo. Food. I figure that, with that, I can hole up in my house for some amount of time.”

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.
At seventy-seven, living on a tugboat in Sausalito, Brand is less impressed by signs of fragility than by examples of resilience. In the past decade, the world survived, without violence, the worst financial crisis since the Great Depression; Ebola, without cataclysm; and, in Japan, a tsunami and nuclear meltdown, after which the country has persevered. He sees risks in escapism. As Americans withdraw into smaller circles of experience, we jeopardize the “larger circle of empathy,” he said, the search for solutions to shared problems. “The easy question is, How do I protect me and mine? The more interesting question is, What if civilization actually manages continuity as well as it has managed it for the past few centuries? What do we do if it just keeps on chugging?”

For a time in the 1970s, the terms survivalist and retreater were used interchangeably. While the term retreater eventually fell into disuse, many who subscribed to it saw retreating as the more rational approach to conflict-avoidance and remote "invisibility". Survivalism, on the other hand, tended to take on a more media-sensationalized, combative, "shoot-it-out-with-the-looters" image.[9]
To answer that question, I found myself in the Siloam Cafe in Siloam Springs, Arkansas, seated across from Martin Fletchall, a disabled veteran who says God called him and his family to the Ozarks from Montana. He prefers to be called Fletch. Fletch is in his 40s, wears a white beard, a camouflage hoodie and matching hat and orders toast, eggs and steak, which costs less than $4. He agreed to meet me after a few weeks of exchanging emails and vetting that I wasn’t actually a “social justice warrior.” 
There are a few basics to remember when it comes to finding your way out of the wilderness like finding a stream and following it downhill. This will keep you near a water source and take you out of the worst weather toward civilization. However if the weather is bad and there are no streams to follow you’ll need another method of navigation: the compass.
He gave out supplies initially, but, when the neighbors returned with a crowd, he explained that he needed the rest for his family. The crowd turned antagonistic. The man scared them off with a shotgun, but it wasn't long before they returned throwing bricks through his windows in retaliation. He left soon after with as much of his emergency supplies as he could carry.
The fears were different in Silicon Valley. Around the same time that Huffman, on Reddit, was watching the advance of the financial crisis, Justin Kan heard the first inklings of survivalism among his peers. Kan co-founded Twitch, a gaming network that was later sold to Amazon for nearly a billion dollars. “Some of my friends were, like, ‘The breakdown of society is imminent. We should stockpile food,’ ” he said. “I tried to. But then we got a couple of bags of rice and five cans of tomatoes. We would have been dead if there was actually a real problem.” I asked Kan what his prepping friends had in common. “Lots of money and resources,” he said. “What are the other things I can worry about and prepare for? It’s like insurance.”
When I started putting together my first survival kit, I just collected whatever weird stuff I could find—like tablets that would protect my thyroid from nuclear fallout. My mindset changed when my first daughter was born. I realized I needed a more practical end-of-the-world plan, with equipment that would be useful for things that might actually happen. Nuclear war is probably not in store for 2018, and if it is, I’ll just open a window. I don’t want to live through that.
