I just finished "The Sheer Ecstasy of being a Lunatic Farmer" by Joel Salatin.
This one I am going to have to buy! He crafts small chapters, covering areas of Polyface farms, the land, farming, and big agribusiness. He clearly expresses his feelings about how big business farming has really weakened the world and Nature and people, all for the mighty dollar.
He strongly expresses his views, but is not obnoxious about it, he is amusing as he explains them.
This is one for my bookshelf.
