In the next decade Howard Ruff warned about socio-economic collapse in his 1974 book Famine and Survival in America. Ruff's book was published during a period of rampant inflation in the wake of the 1973 oil crisis. Most of the elements of survivalism can be found there, including advice on food storage. The book championed the claim that precious metals, such as gold and silver, have an intrinsic worth that makes them more usable in the event of a socioeconomic collapse than fiat currency. Ruff later published milder variations of the same themes, such as How to Prosper During the Coming Bad Years, a best-seller in 1979.
Another concern when you’re lost in the wild is where to procure potable water. Sometimes there will be bubbling streams of crystal clear water rolling down wooded hillsides to fill your water bottle and sometimes you’ll have little more than a stagnant pool standing between you and dehydration. The LifeStraw Personal Water Filter is survival gear that can turn that stagnant pool into a lifesaver.
The LifeStraw filter meets EPA standards and has been shown to remove more than 99.9% of waterborne parasites and bacteria. Humanitarian relief workers in all corners of the globe use the LifeStraw to help bring safe water to threatened communities and refugee camps. The “straw” itself weighs a scant 0.1 pounds and measures 9” in length and 1” in diameter. Few things are worse than being lost and being besieged by waterborne illness. Bring this essential piece of survival gear with you whenever you venture into the wild and make sure water problems are not on the menu.
Survivalists' concerns and preparations have changed over the years. During the 1970s, fears were economic collapse, hyperinflation, and famine. Preparations included food storage and survival retreats in the country which could be farmed. Some survivalists stockpiled precious metals and barterable goods (such as common-caliber ammunition) because they assumed that paper currency would become worthless. During the early 1980s, nuclear war became a common fear, and some survivalists constructed fallout shelters.
In tropical areas, a survival kit may have mosquito head netting, additional insect repellent, anti-fungal cream, a machete, water purification tablets, foot powder, matches, a flint strike, a compass, a wire saw, a space blanket, medical equipment (gauze pads, elastic gauze bandage, antiseptic creams, anti-malaria tablets, anti-infection tablets, bandages, etc.), salt tablets, a fishing kit, snare wire, extra socks, a candle, a signal mirror, flares, a sewing kit, safety pins, tinder, tape, a whistle, and rations.
The term "survival kit" may also refer to the larger, portable survival kits prepared by survivalists, called "bug-out bags" (BOBs), "Personal Emergency Relocation Kits" (PERKs) or "get out of Dodge" (GOOD) kits, which are packed into backpacks, or even duffel bags. These kits are designed specifically to be more easily carried by the individual in case alternate forms of transportation are unavailable or impossible to use.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
