George DeVault, President and Executive Director of Seed Savers Exchange, notes in their 2009 Harvest Edition (page 1): "Nationwide, there has been an explosion in home gardening. The National Gardening Association (http://www.garden.org/) estimates there was a 19 percent increase in food gardens in 2009. That is 7 million new gardens!" (Exclamation point is his own.)
He goes on to say Seed Savers Exchange has seen even greater growth. Membership alone has increased by nearly 60 percent over last year. As you may know, Seed Savers Exchange is "a non-profit organization of gardeners dedicated to saving and sharing heirloom seeds." http://seedsavers.org/
While Gardens are surely up during periods of economic uncertainty, I believe that something deeper is going on. We are surely finding some lessons in these times about what is important. In the face of those lessons, we are beginning to make a different set of choices.
The People are coming home to whom they have been meant to be. Get ready. We are on the edge of the Revolution for which we have deeply yearned. It is the work of our Time.
