As a city dweller, I knew I wanted the skills to live anywhere. So, I've lived off the land, lived on a very small farm and am back in the city. Why? Just go to YouTube and search perma culture.

Once a perma culture set up is established, an area the size of a football field can feed 100 families for one year with one person maintaining it! In my city, there are homes that you cannot see if you are standing in the street looking at it, because of the "food forest."

If you set up a food forest, it won't provide food overnight, but it is a great way for city dwellers and/or country people to raise food.

I've tried to get my town to convert some of the city parks into at least partial food forests so people can learn how to do this in their yard or even on a patio in pots. So far, I haven't been successful but that's okay. At least it's getting people to think. Spread it around and see what happens in your area.
