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.

Adherents of the back-to-the-land movement inspired by Helen and Scott Nearing, sporadically popular in the United States in the 1930s and 1970s (exemplified by The Mother Earth News magazine), share many of the same interests in self-sufficiency and preparedness. Back-to-the-landers differ from most survivalists in that they have a greater interest in ecology and counterculture. Despite these differences, The Mother Earth News was widely read by survivalists as well as back-to-the-landers during that magazine's early years, and there was some overlap between the two movements.
When Hurricane Sandy hit New York in 2012, Charles realized he needed to prep for a more immediate threat. While Manhattan emerged primarily unscathed, the devastation wrought across the coast of New Jersey, Staten Island, and Queens struck him. The city was able to recover quickly, but if something more catastrophic hit next time, like Hurricane Katrina in 2005, he wasn't so sure.
Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.
Jack Matthews, an American who is the chairman of MediaWorks, a large New Zealand broadcaster, told me, “I think, in the back of people’s minds, frankly, is that, if the world really goes to shit, New Zealand is a First World country, completely self-sufficient, if necessary—energy, water, food. Life would deteriorate, but it would not collapse.” As someone who views American politics from a distance, he said, “The difference between New Zealand and the U.S., to a large extent, is that people who disagree with each other can still talk to each other about it here. It’s a tiny little place, and there’s no anonymity. People have to actually have a degree of civility.”

When bands of marauders start roaming the streets, how are you going to keep them out? Tear down a few walls, says Timothy Ferraro, a twenty-five-year construction veteran who's thought about this situation plenty while watching The Walking Dead. "Assuming the attackers don't have a battering ram, you should be able to keep them out using the lumber and drywall already in your home," he says.
