My thoughts: This is not a book about how to grow rows of corn or beans or orchards of fruit. It doesn't tout the home "victory type" garden. A variety of different concepts of farming and the things, or commodities, farmed is presented to the reader.
For example, there is a quick look at farming "salt" from sea water or farming oysters in baskets immersed in the ocean. Different from normal grocery store food item farming. Interesting because it gives a glimpse into other foods and methods of farming that need to be considered for consumers needs and the future of farming those different commodities.
