I watched a video on the sift of a cute little girl who kept saying "Old Fock". I followed the link to this cute little family who decided to live in a Bus. They got a bus and converted it into an RV of sorts and drove it around the US and Canada visiting Organic farms in order to write a book about them, so others can learn from those Organic farmers.
That is her book for Organic Farmers and she has a new book called "Food Tyrants" coming in 2013.
I really think you should make your way through their videos, from the beginning. You'll fall in love with this family, and their mission too. They're fighting for our right to clean, healthy food. Their journey starts here.
