Survivalism is a social movement of individuals or groups (called survivalists or preppers) who proactively prepare for emergencies, including natural disasters, as well as disruptions to social, political, or economic order https://www.preppershowsusa.com/prepper-show/be-prepared-expo-2022/ Preparations may anticipate short-term scenarios or long-term, on scales ranging from personal adversity to local disruption of services, to international or global catastrophe. Survivalism may be limited to preparing for a personal emergency, such as job loss or being stranded in the wild or under adverse weather conditions. The emphasis is on self-reliance, stockpiling supplies, and gaining survival knowledge and skills. Survivalists often acquire emergency medical and self-defense training, stockpile food and water, prepare to become self-sufficient, and build structures such as survival retreats or underground shelters that may help them survive a catastrophe. Use of the term survivalist dates from the early 1980s ( .en.wikipedia.org/wiki/Survivalism ).
