I have written several posts on growing food locally. My last post was on the potential demise of food production in the San Joaquin Valley due to all the salt that's in the irrigation water.
Today I watched the PBS video archive of Bill Moyers interviewing Michael Pollan and encouraging him to accept, if offered, the cabinet post of Secretary of Agriculture in the Obama cabinet.
Instead of suffering through more of my verbosity on the subject of local food production, I encourage you to view this two-part video interview.
Never Hunger, Never Thirst!
