"There are three ecosystems today: the ecosystem of species, the ecosystem of intellectual disciplines, and the ecosystem of nations. The ecosystem of species is the direct concern of this book ; it needs to be understood and cherished not only for itslef but also because it provides models of interdependence which suggest how other systems might behave. The interactions of diverse intellectual discipines throughout this book reveal some of the interdependence within the ecosystem of ideas. And the context of many of the essays -- global scarcity and coompetition -- suggests some of the interdependence in the ecosystem of nations."--Preface.
