This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear.[31] The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. [33]

With goTenna you use a simple smartphone messaging app as a platform for sending SOS messages along with your handheld hunting GPS coordinates should you need emergency help. You can also use it to chat with emergency services so they know your exact condition and can prepare accordingly. It’s off-grid survival gear at its best and could be the difference between life and death.


During his 45th Infantry Division, Pense taught field wiring, instructing G.I.s on setting poles and stringing wires to rig together a communications network from scratch. After the war, he was an electronics engineer in the private sector, sometimes on military contracts, learning the frailty of the nation’s power grid firsthand. On one government contract, he witnessed a nuclear warhead knock out power in Hawaii after detonating high above the Pacific.
James Patrick Douglas, a man of the land in Maine, shows off homesteading techniques he believes will become necessary based upon overpopulation fears; Larry Hall turns an underground missile silo into a bunker to make sure his family is safe during any event; Becky Brown (of Grab n Go Food Storage) is making sure she and others are ready for martial law.
Worms are edible (although certainly not desirable for most) and if you can find fresh water you might be able to rustle up some crustaceans to eat.  If you’ve ever had crab or lobster, crayfish are like their mini cousins, all of which are edible.  If you are near saltwater, you can try to capture shrimp, crabs, lobsters, and more in waters approximately ten meters deep.  Mollusks include all of the following food sources you can sometimes find while out in the wild: sea urchins, chitons, periwinkles, barnacles, bivalves, mussels, clams, and snails.
Some evangelical Christians hold to an interpretation of Bible prophecy known as the post-tribulation rapture, in which the world will have to go through a seven-year period of war and global dictatorship known as the "Great Tribulation". Jim McKeever helped popularize survival preparations among this branch of evangelical Christians with his 1978 book Christians Will Go Through the Tribulation, and How To Prepare For It.
