Won't be long before you'll have to resurrect that old Victory Garden mentality and supplement your WalMart Super Center groceries with the old fashioned kind --- home grown!
Lawns will be replaced with rows of pole beans and potatoes. Swimming pools will be filled with corn and tomatoes (after the soil is added, of course). Mother Earth News will break all circulation records. And people will start getting slimmer. Maybe that's a good thing.
Oh, and your Homeowner's Association will also be forced to approve raising backyard sheep, goats and pigs. Make that frontyard, too.
