Survivalism is a social movement of individuals or groups who proactively prepare for emergencies, such as natural disasters, and other disasters causing disruption to social order caused by political or economic crises. 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. There is no bright line dividing general emergency preparedness from prepping in the form of survivalism, but a qualitative distinction is often recognized whereby preppers/survivalists prepare especially extensively because they have higher estimations of the risk of catastrophes happening. Nonetheless, prepping can be as limited as preparing for a personal emergency, or it can be as extensive as a personal identity or collective identity with a devoted lifestyle.

A global catastrophic risk or a doomsday scenario is a hypothetical event that could damage human well-being on a global scale, even endangering or destroying modern civilization.
