Doomsday Preppers was an American reality television series that aired on the National Geographic Channel from 2011 to 2014. The program profiles various survivalists, or "preppers", who are preparing to survive the various circumstances that may cause the end of civilization, including economic collapse, societal collapse, and electromagnetic pulse. The quality of their preparations is graded by the consulting company Practical Preppers, who provide analysis and recommendations for improvements.
More specifically, we want to avoid allocating our savings so heavily to any particular asset class (like U.S. stocks) that a really bad bear market in that asset class destroys our portfolio returns. And ideally we want to spread our savings around into different asset classes (like maybe developed market foreign stocks or US Treasury bonds) so if one asset class’s value zigs, another asset class’s value zags.
Robyn Gershon, a public-health professor at N.Y.U. who specializes in disaster preparedness, concedes that, in the age of global warming, it is not so outlandish to be thinking about the apocalypse. Per the “push-pulse theory of extinction”—a theory devised to explain the mass death of the dinosaurs—any strain on an ecosystem leaves the species in it far more vulnerable to cataclysm. Today, climate change and rising sea levels put us at greater risk of being wiped out by a disastrous event, such as a pandemic or a supervolcano.

I'm not quite crazy enough to say that epinephrine will help you survive the inevitable zombie apocalypse (you can go here for that).

Many books were published in the wake of the Great Recession from 2008 and later offering survival advice for various potential disasters, ranging from an energy shortage and crash to nuclear or biological terrorism. In addition to the 1970s-era books, blogs and Internet forums are popular ways of disseminating survivalism information. Online survival websites and blogs discuss survival vehicles, survival retreats, emerging threats, and list survivalist groups.
Survivalists maintain their group identity by using specialized terminology not generally understood outside their circles. They often use military acronyms such as OPSEC and SOP, as well as terminology common among adherents to gun culture or the peak oil scenario. They also use terms that are unique to their own survivalist groups; common acronyms include:
