During the Cold War, when the US and the Soviet Union regularly let the other know that they had enough nukes to destroy the earth 100 times over (what was even the point of that?), more and more people built fallout shelters. These were underground living quarters that had beds, bathrooms, diesel fuel tanks for the generators, water cisterns, and enough food to last a family of five until the fallout from the nukes had settled into the water table and would let you die a horrible death from cancer instead of killing you instantly in a fiery explosion.
Some of the better-equipped modern shelters have an underground hydroponic garden so the poor survivors can have fresh fruits, vegetables, and herbs. In addition, grey water used for cleaning can feed algae that cleans the water and provides fresh the air for the inhabitants. As with everything in the 21st century, the market of survival supplies has grown into a multi-million dollar industry, boutique farmers trying to one-up each other developing designer crops for the nuclear age.
The latest offering is the "doomsday pepper." It is a purple bell pepper that combines the best attributes of the green and red, can be grown without soil and with minimal water, and can survive for up to three weeks without light—just in case the generators break down. Even better, they can be easily dried and rehydrated.
So, if your fear of nuclear war, zombies, or aliens is second only to the horror of a life without salsa, check out the doomsday pepper. They're available at the more reputable
doomsday prepper supply stores.
