Enough about eggs. The other food I was thinking about was fruits and vegetables. I will agree with Barbara Kingsolver in her book "Animal, Vegetable, Miracle" when she states "The main barrier between ourselves and a local-food culture is not price, but attitude." She describes the North American consumer as impatient. We want strawberries in January, etc. "Waiting for the quality experience seems to be the constitutional article that has slipped from American food custom" Waiting for each vegetable to come to season is analogous to Christmas morn. When attitudes can be changed from a consumerist "want" to a manageable "wait", only then can a local-food movement become sustainable.
Another challenge to the local-food movement is that the sheer volume of food required to feed large populations is just too great for the local supply. I envision many small backyard plots used for vegetable growing. The backyard farms could either be farmed by the owner of the property or rented out to "urban farmers" who would harvest the vegetables and sell them at local farmers markets. May I suggest a tax-free incentive both to the farmers and the land-owners?
There are many more challenges to essentially undo the mistakes we have made in food production, but hopefully attitudes can change.
