Quite a few authors write about situations which probably only constitute a partial collapse of society as we know it. Such situations include those where there still exists some semblance of trade or even transportation of some goods. Perhaps some vestige of government is even functioning. What if a disaster happens and we are left with even less than that.
At the risk of being criticized for being too much of a pessimist, I would suggest that a thoughtful prepper should consider planning to survive a really serious collapse of society. (TEOTWAWKI.)
First of all, without the constant assistance of society and a modern economy, most of the people in the world would die; after making a desperate effort to hold onto life . This is not news to many but some of the ramifications of this might be. The untreated human waste caused by the unprepared is an obvious problem. Feces carries disease and the lowly fly is a prolific carrier of many these serious diseases. Flies also like carrion and an unburied carcass is a health hazard too .
