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.
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. 
“How do I tell Dr. Norman Shealy that he was voted out of the meetup?” Finelli asks, rhetorically. “So I told him on-air. I said, ‘Dr. Shealy, they had a vote, and you were voted to be barred from the meeting.’ And he kind of laughed, and I said don’t get all excited, they banned me, too.” He holds no grudges; he says he’s actually glad it happened. Now he knows how his students really felt.
But mothers like Nygaard, Luther, and Bogwalker probably don’t need to a sociologist to remind them of that: They’re busy taking care of the kids, cooking, cleaning, running their own business, and doing their best to ensure that everyone around them has everything they need. It can be hard to draw the line between being a mom who is a survivalist and simply being a mom who lives her life with an eye to the future, but maybe that’s kind of the point: In giving traditional “women’s work” a name — like prepping or homesteading — they’re simply making that work more visible.
The Cold War era civil defense programs promoted public atomic bomb shelters, personal fallout shelters, and training for children, such as the Duck and Cover films. The Church of Jesus Christ of Latter-day Saints (LDS Church) long directed its members to store a year's worth of food for themselves and their families in preparation for such possibilities; but the current teaching advises only a three-month supply.
Since people began building fallout shelters during the Cold War, canned nonperishable food has been recognized as great to have around when the going gets tough. Freeze-dried food and MRE (Meal, Ready-to-Eat) military rations with years of shelf life are also good options that take up less space per available calorie. [Doomsday Facts (and Fictions)]
