I prefer the phrase 'living with the land.' Living off Mother Nature sounds like a deadbeat boyfriend. The 1970s saw a post hippie era 'back to the land movement' fueled largely by Mother Earth and RODALE PRESS, publisher of countless and frustratingly short print run books on countless related subjects. Socially it was partly usurped by the survivalist ideology that imploded with Ruby Ridge and that brilliant academic but social moron and plagairist the Unabomber. But lots of people are doing this, many modern homesteaders in Alaska, practitioners of 'the primative movement'- which I first thought was going without TP, and countless others.
