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.
Tinder: This fire-starting source consists of dry material. The dry material you can use to ignite the fire from a spark you create. If the tinder is not perfectly dry however, your fire starting efforts will come to naught. Tinder sources include tree resin, bark, dry grass, dried leaves, and paper. Lint from the drier also proves an outstanding fire starter, as does steel wool.
People who are not part of survivalist groups or apolitically oriented religious groups also make preparations for emergencies. This can include (depending on the location) preparing for earthquakes, floods, power outages, blizzards, avalanches, wildfires, terrorist attacks, nuclear power plant accidents, hazardous material spills, tornadoes, and hurricanes. These preparations can be as simple as following Red Cross and U.S. Federal Emergency Management Agency (FEMA) recommendations by keeping a first aid kit, shovel, and extra clothes in the car, or by maintaining a small kit of emergency supplies, containing emergency food, water, a space blanket, and other essentials.
The kits provided for Soviet and Russian Cosmonauts are optimised for survival in the temperate and sub-arctic mountains, forests and grasslands in the east of the country. Soyuz spacecraft kits include "food rations, water bottles, warm clothing, rope for making a shelter using the capsule’s parachute, fish hooks and miscellaneous other survival gear". The TP-82 Cosmonaut survival pistol, was provided to defend against predators such as wolves or bears. It was able to fire conventional bullets, shotgun cartridges and flares; the folding stock could be used as a shovel and it also had a fold-out machete.[8]

Individual survivalist preparedness and survivalist groups and forums—both formal and informal—are popular worldwide, most visibly in Australia,[93][94] Austria,[95] Belgium, Canada,[96] France,[97][98] Germany[99] (often organized under the guise of "adventuresport" clubs),[100] Netherlands,[101] New Zealand,[102] Russia,[103] Sweden,[104][105][106] the United Kingdom,[107] and the United States.[23]

“That’s a major problem,” says Gene Louis, a New Jersey expat who attended his first meetup in 2013 after moving to Springfield to begin ventures in real estate brokerage and digital marketing. Plus, Jersey is expensive, and he doesn’t like the fact that its residents don’t pump their own gas. “You don’t know what people are going to define as a threat, don’t know what people at survival meetings are going to talk about,” he says. “You can’t prepare for 100 percent of what’s on that list—well, you’d need to be Donald Trump to afford to.”
