An “expanded” environmental philosophy is one that does two things: it retains some of the key features of revised environmental philosophy (e.g., consequentialist and rights-based theories) while also introducing genuinely new features—ones that had not yet been part of a moral theory. This essay considers only one “expanded” environmental philosophy, Aldo Leopold's “land ethic”, published as an essay, “The Land Ethic”, in his 1949 book The Sand County Almanac. Many environmental philosophers consider Leopold's land ethic the first genuinely environmental ethic (not just an “animal ethic”).  It is discussed here because many feminist environmental philosophers defend positions that draw on Leopold's land ethic (e.g., Chris Cuomo 1998; Deane Curtin 1999; Warren 2000).
