First of all what is survival? It is quite simply what we’ve all been doing since we were born. We provide for ourselves shelter, fire, water, medical, food, and social life, these are the foundation of our existence. Without these core principals, our very existence is at risk.
There is a common misconception among people who have never eaten MRE’s that they are the same as backpacking meals. (I’ll even admit to being this naive in the past) They are both lightweight meals on the go; that’s about where the similarities end.
