How much yard would you need if you wanted to live off the land and provide a family of four with food? With backyard gardens making a comeback, people are once again wondering about food self-sufficiency.
The image above lays things out in an interesting, and thought-provoking way that helps illustrate some of the demands we place on the productive capacity of the Earth as we eat our way through life.
If you click on the image you won't need a magnifying glass to read it. If you don't click on the image, then I should share with you that the authors estimated that a family of four could become food self-sufficient on about 2 acres of land, depending on things like soil fertility, and whether your diet is vegetarian or not.
Even if you can't become food self-sufficient yet, a backyard garden is always a good thing.

Utilizing a greenhouse can extend the growing season allowing for more yield in a smaller growing area. I think it's great that backyard gardens are again gaining in popularity and hopefully the whole family will be involved.
