Zombie apocalypse: Used by some preppers as a tongue-in-cheek metaphor for any natural or man-made disaster and "a clever way of drawing people’s attention to disaster preparedness". The premise of the Zombie Squad is that "if you are prepared for a scenario where the walking corpses of your family and neighbors are trying to eat you alive, you will be prepared for almost anything." Though "there are some... who are seriously preparing for a zombie attack".
We get that creature comforts will be ever more important as the things that used to make us happy slowly break and crumble around us. But do you really want to put a ton of effort into opening a bakery when everything is going to shit? And we hate to be the bearers of bad news, but no amount of odor elimination is going to stop the uncivilized world from smelling really, really bad.
People who are not part of survivalist groups or apolitically oriented religious groups also make preparations for emergencies. This can include (depending on the location) preparing for earthquakes, floods, power outages, blizzards, avalanches, wildfires, terrorist attacks, nuclear power plant accidents, hazardous material spills, tornadoes, and hurricanes. These preparations can be as simple as following Red Cross and U.S. Federal Emergency Management Agency (FEMA) recommendations by keeping a first aid kit, shovel, and extra clothes in the car, or by maintaining a small kit of emergency supplies, containing emergency food, water, a space blanket, and other essentials.
