Mainstream economist and financial adviser Barton Biggs is a proponent of preparedness. In his 2008 book Wealth, War and Wisdom, Biggs has a gloomy outlook for the economic future, and suggests that investors take survivalist measures. In the book, Biggs recommends that his readers should "assume the possibility of a breakdown of the civilized infrastructure." He goes so far as to recommend setting up survival retreats: "Your safe haven must be self-sufficient and capable of growing some kind of food," Mr. Biggs writes. "It should be well-stocked with seed, fertilizer, canned food, medicine, clothes, etc. Think Swiss Family Robinson. Even in America and Europe, there could be moments of riot and rebellion when law and order temporarily completely breaks down."
Civilians such as forestry workers, surveyors, or bush pilots, who work in remote locations or in regions with extreme climate conditions may also be equipped with survival kits. Disaster supplies are also kept on hand by those who live in areas prone to earthquakes or other natural disasters. For the average citizen to practice disaster preparedness, some towns will have survival stores to keep survival supplies in stock.
The kind of gear you need – It’s easy to get obsessed with survival gear and start accumulating every new product that comes on the market. If you have money to burn and engage in a variety of backcountry activities this might be a sound strategy. Most people however decide pretty early on what type of outdoor activity floats their particular boat and as such any survival gear should have some sort of relationship to that activity. Everyone, for instance, should have an emergency whistle with them but not everyone will need an extreme sleeping bag. Everyone will need first aid items but not everyone will need to carry croval shovel or a tactical watch or field watch. If you’re a mountaineer you’ll probably want that shovel, especially if you’re climbing in the winter. If you’re going on a day hike and aren’t bringing food that requires preparation there’s no need for a mess kit and so on.
Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.
Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
