I don’t encounter any preppers at the school that day, but I do meet women from all over the United States and with all kinds of reasons for wanting to learn how to cut and drill wood, including a young yoga studio employee from Wisconsin who is building some custom shelving for her kitchen appliances and cookbooks, as well as two seniors from Washington, DC, who want to build a set of matching cabinets to house their prized collection of vintage wine glasses. Down by the garden, I meet a pair of women from Missouri who are hoping to go into business flipping houses. “We’re tired of waiting for our husbands to do it,” one of them says.
Anarcho-primitivists share many characteristics with survivalists, most notably predictions of a pending ecological disaster. Writers such as Derrick Jensen argue that industrial civilization is not sustainable, and will therefore inevitably bring about its own collapse. Non-anarchist writers such as Daniel Quinn, Joseph Tainter, and Richard Manning also hold this view. Some members of the Men Going Their Own Way subculture also promote off-grid living and believe that modern society is no longer liveable.
Zombie apocalypse: Used by some preppers as a tongue-in-cheek metaphor for any natural or man-made disaster and "a clever way of drawing people’s attention to disaster preparedness". The premise of the Zombie Squad is that "if you are prepared for a scenario where the walking corpses of your family and neighbors are trying to eat you alive, you will be prepared for almost anything." Though "there are some... who are seriously preparing for a zombie attack".
Contrary to what a lot of people think, the most important thing you need to survive a disaster is water. The body can go weeks without food but only a few days without water. And once you start getting dehydrated, there goes your energy levels, your clear-headedness, and your ability to make rational decisions. You will need this gear to ensure your supply of water:
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.
Most of us have quite good shelter already available to us. If you live in a cold climate you have to be concerned about winter and freezing temperatures if you don't have a fireplace and wood available. If things ever really became bad I would setup a tent inside of my house and burn candles inside of the tent. For most of the continental United States that would keep the temperature inside of the tent above freezing. If you combine that with a zero degree or better sleeping bag you will survive much better than just about anyone around you. It's much easier to achieve this level of heating independence than finding a way of powering your generator for weeks. A little known fact is that most generators recommend changing their oil every 40 hours of use. Storing fuel to keep a generator working is daunting but the oil requirements are almost always forgotten.
And so, while I don’t think I’m newly paranoid, I am newly...prepared. Fortunately, the internet provides both camaraderie and online shopping for people who can vividly imagine literally every terrible scenario, and I quickly found myself down a rabbit hole of opinions on what I, my husband, and two small kids need, for, say, two weeks in an apartment with no access to food, water, heat, or medical attention. Or what we’ll need for a fast skedaddle out of town. But I persevered, and bought what I think is the bare minimum for health and safety in the event of a disaster. Below, everything I have in either my emergency supply kit or our “go bags,” or both.
Dozens of websites and books offer advice on supplies to have on hand and in stock if "the end of the world as we know it" – TEOTWAWKI, as it's known in survivalist circles – comes to pass. Here, then, is a rundown of the supplies you'll need to ensure that this proverbial "end of days" is not an end for you and yours, but rather a new beginning.
