content: I have read most of Michael Pollans books. I think 'The Omnivores Dilemma' is a five-star plus book that should be mandatory reading for everyone who eats, and 'In Defense of Food' is almost as good.In this book, Michael talks about his efforts at gardening, both vegetables and ornamental plants. However, this book disappoints. It is too vague, with few concrete examples to back up his assertions. It seems that Michael is a better writer about other peoples efforts at producing food than he is on his own efforts.
