A good idea is to buy a book that covers natural fauna food sources.

With practice, edible plants, tree parts and roots are easily identifiable and once you know what to look for, you will be amazed at how many options you have – no matter where you are.

A walk in a regular city park can yield literally dozens of food sources available in a survival situation.

That number is even higher in a wild setting where plants and trees are more abundant.
