This book assumes that you will be 'surviving' in North America, probably in the Northern woods. While it has aged better than many other books, it does not take the vulnerabilities of the environment into account the way we would today. (Survival of one/a few human(s) is more important than protection of animals, ecosystems?)

The kit he recommends is much heavier than most people can carry (or his own guidelines). Much of it is also of more use to those with the sort of experience that would make the book superfluous. ( )
