Let's just say that for some reason, all the modern conveniences that we have now were gone. For whatever reason, it doesn't matter. How many would survive? How many of today's young people know how to hunt, plant gardens, cook on the open fire or even chop wood to keep warm. It would be an interesting scenario wouldn't it?
I used to write TEOTWAWKI fan fiction, though I still write occasionally. (Just not fan fiction) Researching for a TEOTWAWKI story is depressing. It is amazing how much total garbage masquerading as knowledge is out there on the net.
Realistically, unless human nature changes, do not write off humans in general. Large amounts will die, but through every major event in history humans survive. What is odd is that preparation was never the key. Attitude was the key. Those determined to survive tended to find a way to survive. Those who held too tightly to the past, or whom refuse to change despite circumstances tend to die.
Below is a highly possible outlook, though there is no possible way to envision an actually probable scenario. Far too many variables.
- For most people, in a general sense, most of those who initially die would succumb to dehydration.
- Disease or physical conditions would kill off many more.
- Old man Murphy would have a field day with numerous others.
- Due to lack of food resources, a great number would die, especially those who have food when nobody else does.
- Those without food would eventually kill most of those obviously with food. (Not enough bullets for those with the defense mindset. They underestimated their opponent and his determination. Always a fatal mistake.)
- A good portion of those who survive to this point would starve.
- A fraction of humanity would exist, and numerous whole sections of these would succumb to 'acts of god' (drought, insects eating crops, etc.)
Doesn't make for a good story, so I never wrote it. However, in our country's history even the old west was full of such happenstance to preppers of the time (settlers). Modern preppers are actually less well equipped for true survival then the settlers of the 19th century.
The difference? Basic knowledge of how to survive without electricity and gasoline.
Yet settlers made the same human mistakes, and often they died in droves. Sometimes whole communities. One drought could mean life or death to hundreds or thousands.
Truthfully? The uber advanced nations are toast, with their populations being the hardest hit of all nations. They are too civilized to learn such base knowledge as what they can eat from the wild field behind their own house, or how to live without manufactured 'stuff'.
Knowledge, or rather the lack of it, will kill most people in TEOTWAWKI. Specifically the knowledge that stuff can't save you in a post apocalyptic world.
PAW fiction was fun to write, but it was a bunch of fairy-tales when viewed towards usable practicality. The real stuff nobody would want to read.
