Since nature has the most sustainable ecosystem and since ultimately agriculture comes out of nature, our standard for a sustainable world should be nature's own ecosystem.
Wes JacksonThe dialectical or ecological approach asserts that creating the world is involved in our every act. It is impossible for us to operate in our daily lives and not create the world that everyone must live in. What we desire arranges the genetic code in all of our major crops and livestock. We cannot avoid participating in the creation, and it is in agriculture, far and away our largest and most basic artifact, that human culture and the creation totally interpenetrate.
Wes JacksonAs we search for a less extractive and polluting economic order, so that we may fit agriculture into the economy of a sustainable culture, community becomes the locus and metaphor for both agriculture and culture.
