"A land ethic...reflects the existence of an ecological conscience, and this in turn reflects a conviction of individual responsibility for the health of the land. Health is the capacity of the land for self-renewal. Conservation is our effort to understand and preserve this capacity."

Political institutions, no matter how well or badly designed, depend for continued existence upon acting men; their conservation is achieved by the same means that brought them into being. Independent existence marks the work of art as a product of making; utter dependence upon further acts to keep it in existence marks the state as a product of action.
