Survivalism is a movement of individuals or groups (called survivalists or preppers) who are actively preparing for emergencies, including possible disruptions in social or political order, on scales from local to international. Survivalists often acquire emergency medical and self-defense training, stockpile food and water, prepare to become self-sufficient, and build structures (e.g., a survival retreat or an underground shelter) that may help them survive a catastrophe.

Anticipated disruptions may include:

Clusters of natural disasters, patterns of apocalyptic planetary crises, or "Earth Changes" (tornadoes, hurricanes, earthquakes, blizzards, solar storms, severe thunderstorms, floods, tsunamis).
Anthropogenic disasters (chemical spills, release of radioactive materials, nuclear or conventional war, oppressive governments).
The general collapse of society caused by the shortage or unavailability of resources such as electricity, fuel, food, or water.
Financial disruption or economic collapse (caused by monetary manipulation, hyperinflation, deflation, or depression).
A global pandemic.
Widespread chaos or some other unexplained apocalyptic event.

My Prepper ties began in religion where I felt compelled to join all religeons since they were all claiming to be the one and only true faith. My education has been along prepper lines now that I have mastered wilderness survival and survival in just about any conceivable situation. Presently I’m pushing Uncle Sam to replace war mongering with global security from incoming astroid deflection and the advancement of potential space mining.  

I'm a mini prepper b/c I don't have the room, like those people on TV do. But, yes, I put away canned goods and jugs of water, and I rotate them . And I keep a flash light down there. I'm going to get one of those flashlight that you just wind up ......doesn't depend on batteries.
