Creating a "Farm City": A responsive book review

Recently, kind of by accident, I had the pleasure of discovering and meeting Novella Carpenter.  I was so impressed with her book Farm City: The Education of an Urban Farmer

and can't wait to visit and revisit her new book The Essential Urban Farmer. I was impressed at her poetry and honesty about the realities of raising and butchering animals. And the whole thing combined with my reading of Green Metropolis had me wishing for a Utopia in which city dwellers can only have yards if they will relegate and utilize them for something with ecological usefulness: habitat, water purification, food sources for local organisms, or food production by themselves or their green thumb neighbors. [Update: For a good laugh, go here to see what God might think of your yard] Everyone else must live in hip urban apartments...One can wish.
