Years ago, I was reading the book Surviving the Apocalypse in the Suburbs. (Great book that I highly recommend!) The premise of the book is that our future economic woes will be based on the scarcity of oil.
The author, Wendy Brown, makes an excellent case regarding our dependency on oil, but the thing that really stood out in my mind was how she had changed her family's diet well in advance of this economic crisis. She focused her efforts on local food for self-reliance in the long run.
She discussed at length the fact that on her suburban property, in her particular climate, there were things she could produce, and things she could not. Taking it a step further, there were many things that were not available within 100 miles of her area. So why, she asked, would she want to base her family's diet on foods that might not be readily available in the future? Why would she want her children to have to endure yet another drastic change should things all go to heck? Instead of rice, they focused on potatoes, for example, because that was realistic for a long-term diet in her location in rural Maine.
Eating locally means stepping away from the Standard American Diet
