"Those should be sobering points and hopefully the producers will point them out to the people who might not realize how extreme it is."

I wish you were right, but right now at least 10 unprepared guys are getting ready to head north inspired by another failure.

Why does a love of camping in the UK mean an ability to live off the land in a harsh cold environment where the natives where required to move extensively to live and their population was controlled by the limited food supply?

Did he do any real survival training in the Yukon?
Did anyone try to finds out how many calories he could hunt in the area each day? and then see how far it was below his BMR?
(PS I have a nice chart that actually tells you the calories of native foods and with it you can cross reference your 'catch' to see how many calories you are actually consuming.)
Did anyone look back at all the other failed attempts and see if he could be sent out better prepared?

I cannot believe that so little preparation was actually done by these so called 'professional' filmmakers.
