The whole point of the show is to show the extreme things you can do to survive in extreme life threatning situations. Out of the stuff you just listed, what one is inacurate?
For example, the crossing of a freezing river just because it is quicker... So If you had a choice between crossing the freezing river to get to shelter OR certain death from hypothermia if you didn't cross the river, you would just sit and die? Same thing with all the others. If faced with certain death otherwise, what one of the things you listed would you not do?
I guess you just don't get the point of the show. It is to entertain, and to provide information... He is not showing things you would do on a normal camping trip. He is showing basic survival skills that in my honest opinon are not innacurate.
