This way of thinking is why most people wouldn't survive a major catastrophe. They think they know so much but having chickens that eat feed store food---already prepared for you--does not make you a survivalist.
You have to be more than that...and it isn't about what you have already done..although that helps. It helps if you have the knowledge on how to butcher animals and eat wild plants and tie knots...sure...if the catastrophe allows there to be wild animals and plants and rope still....but it might not.
Sure the more you know the better...that just makes sense. Learn everything you can!
However, I really think that the people who would make it through a major catastrophe are the ones who can make due with what they have. They are the people who can:
-fix a plumbing problem without calling the plumber
-make a fire without a match or a lighter or a store bought "fire stick" etc.
-gather wood without an ax
-make or find clean water without a filter
-find or make shelter
-take what they needed if necessary
The list could go on and on but basically, it is the people who can "Think". Those who can make something out of nothing ...and you can't "teach" that.
Well, maybe you can. I grew up "doing without". I grew up "making due". It comes pretty naturally to not buy what I can make--to actually shun buying what I can make.
But that isn't all..you would have to have the ability to take what you needed if all else failed and you couldn't get it yourself...and some people think they would never do it...and I think they wouldn't make it...or they don't really understand how the survival instinct in humans works because we can justify a lot of things..but humans have been justifying taking from others to survive for a long time now and in a catastrophic situation they would be justifying a LOT and if you couldn't do it...you wouldn't make it.
Like I said, I don't believe in catastrophic occurrences...I think our society is pretty much beyond that now but if one did occur, I think we would be left with only the people who could "think and live with change".
