How much land are you growing on, if you don't mind me asking?
Also, what are some examples of your carbon imports? Do you use

I grow all my own food, I raise Taro, Malanga, Tropical Yams, and lots

much organic material as I can get for free, I use Daikon most of the

"In the face of all-annihilating weapons, the natural next step may be
the use of no weapons. It may be that the only possibly effective
defense against the ultimate weapon is no weapon at all."
~ Wendell Berry, in '84 (from the essay "Property, Patriotism and
National Defense" as included in the book "Home Economics")
