species is ignored 39 7 Concept is ambiguous and impossible to operationalize J 2 Sustainable Development as Commonly Understood 7 Concept of a sustainable subsystem in an unsustainable global system is fundamentally oxymoronic Concepts like sustainable community sustainable rm sustainable product must be seen as generic indications of goodwill toward environmental issues not an achieved end state
