The path of ecosystem services as a theme in environmental law and policy spans my practice (1982-1994) and academic (1994-present) careers. The importance of nature to human well-being seems so obvious one would think it has been front and center in environmental law and policy since the beginning, but, until recently, that has not been the case. Lately, however, the ecosystem services framework has catapulted this theme into prominence, if not dominance, in environmental discourse.
