I try to occasionally talk on the podcast about foraging for the food that exists in abundance around you, with the idea of guaranteeing oneself the ability to eat regardless of whatever else is going on. There is a lot of information online about foraging, but sometimes it is difficult to glean the good information from the suspect material.
Below are several links (or links to books that are available) about foraging. If listeners have other books that they'd like to share feel free to drop me an email at: chipmonksurvivalpodcast AT gmail.com .

And many more.... (Just do a search online for "foraging" or "foraging for food" and you should come across even more information on this vital topic).
