Ruvio, I wasn't at all sure what you were driving at until someone else mentioned BG.
I would agree with what others have said but on the other hand, if you don't like the content of a thread, don't rise to it! It isn't exactly World's End!
I'll pay you the respect of trying to address some of your points.
Incidentally, I entered your title and got an enormous number of links. I've watched a few episodes of BG's programmes and can't say I'm impressed with the content. I find some of the stunts to be downright irresponsible. A broken leg will not enhance ones chances of survival! My solution is not to watch it!
But you have to put this into context. Not only is it entertainment but is intended in the main for the US market, and there are considerable cultural differences between the US and Europe. I watched a movie on TV last night solely because Clint Eastwood was in it but found it appalling. It wasn't what I'd come to expect from such a talented actor and producer. The reason for this was that it was a movie intended for the US TV market. I'm sure in Eastwood's book, it's only business, and a lucrative business at that!
The reason you got info on how to build a fall-out shelter is because of the difference in meanings between the concepts of "Survival" and woodcraft in different cultural contexts. As an example, consider the disappointment voiced by some at Ray Mears latest "Survival" prog. Most, myself included, looked forward to a production in a woodcraft context of some sort. What we got was a wonderful, and time tested genre of documentaries on the plight of rare or endangered species with a decades old pedigree... and I'm still mad that I missed the last episode!
The fall-out shelter is the product of the decades of the psychology of the (not so) Cold War, with governments terrifying their own citizens into believing the end was nigh, Tomorrow or The Day After Tomorrow!
The notion of man against nature stems from the industrial revolution, when the belief that we could conquer nature with technology was common... Brunel's, Telford's, etc canals, roads and bridges; the Union Pacific Railroad; and a view of nature as being there solely for humans to utilise.
Whereas most contributors to this forum just want to sneak off to the woods, set up camp, build a fire, practice a few skills and maybe even enjoy a dram... without anyone ever knowing they were there, there are other philosophies which insist that only a fool would give a thought to the environment. These are the slash, burn and kill exponents. Those who argue that you shouldn't give a hoot about nature because nature doesn't give a hoot about you.
It's nature that is out to kill you! They call themselves "Survivalists"!
Pit that against my, and many other's belief, that it is nature which will sustain me in a pinch and you're likely to be left with the distinct impression that never the twain shall meet.
