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.
Terrorist attacks including the 911 plane attacks, bombings in London, Madrid, Bali and many other places, led to a strong online interest in discussing personal readiness and self reliance. Fueled by United States disasters such as Hurricane Katrina and Ike and international disasters including earthquakes and tsunamis in Indonesia, Chile, Japan and elsewhere, the Prepper Movement gained a lot of momentum without having a particular date in mind (unlike Y2K) which led to many people recognizing a need to change their lives to be more prepared and self reliant.
This doesn’t mean living in a void, it just means that we’re conscious about our relationship to the world and other people. It’s not rejecting external advice outright, but trusting ourselves enough to sift through which advice is worthy. We’re aware of the agendas of others, and don’t let them sway us from our self-determined path. Self-reliance doesn’t necessarily mean rejecting all established customs and values, it just means experimenting with them so we know if they work for us. It’s putting stock in our inner wisdom.
Shields said that the company noticed an uptick in sales in the months leading up to the 2016 presidential election, and, again last year, amid fears of nuclear escalation with North Korea. Like Wise Company's former CEO Aaron Jackson, whom Bloomberg previously dubbed “America’s Survival Food King,” Shields said he likes to think of Wise’s products as “an insurance policy.”
Also, many who come out here don’t seem to have taken into account ONE aspect that has already marked and recorded their interest in this/these skills. We ALL listed that we came out on here to learn in the least about it and data doesn’t get deleted or lost. (Just saying, we do have a digital fingerprint complete with email, IP address, and every letter typed.)
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.
I read the other day some verses written by an eminent painter which were original and not conventional. The soul always hears an admonition in such lines, let the subject be what it may. The sentiment they instil is of more value than any thought they may contain. To believe your own thought, to believe that what is true for you in your private heart is true for all men, — that is genius. Speak your latent conviction, and it shall be the universal sense; for the inmost in due time becomes the outmost,—— and our first thought is rendered back to us by the trumpets of the Last Judgment. Familiar as the voice of the mind is to each, the highest merit we ascribe to Moses, Plato, and Milton is, that they set at naught books and traditions, and spoke not what men but what they thought. A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the lustre of the firmament of bards and sages. Yet he dismisses without notice his thought, because it is his. In every work of genius we recognize our own rejected thoughts: they come back to us with a certain alienated majesty. Great works of art have no more affecting lesson for us than this. They teach us to abide by our spontaneous impression with good-humored inflexibility then most when the whole cry of voices is on the other side. Else, to-morrow a stranger will say with masterly good sense precisely what we have thought and felt all the time, and we shall be forced to take with shame our own opinion from another.
FEMA’s Individual and Community Preparedness Division (ICPD) is committed to helping local efforts achieve greater community resilience. In order to determine how best to assist local preparedness activities, we conduct periodic research in the field of disaster preparedness to evaluate the nation’s progress with whole community preparedness. These findings are particularly relevant as we prepare our communities for a possible pandemic flu outbreak, hurricane season and other emergency incidents. Furthermore, findings from the research measure the public’s knowledge, attitudes and behaviors relative to preparing for a range of hazards and provide valuable insight for increasing personal preparedness, civic engagement and community resilience. Below are examples of the research FEMA ICPD has conducted:
