Comment: Keep In Mind

The reason for the advancement of civilization is the fact that individuals no longer need to grow their own food. There is nothing wrong with a little bit of self reliance, but it is not possible for everyone in an urban environment. Increased specialization and the distribution of labor is a hallmark of human progress. There are ways to find out where your food comes from if you are concerned about pesticides, etc... That's how organic growers and their customers find each other in the marketplace.
This is not to say that people should not have food storage at home for emergencies, but a return to total individual self-sufficiency is a good indicator of civilization in decline or ending.
