 Other interdisciplinary approaches link environmental ethics with biology, policy studies, public administration, political theory, cultural history, post-colonial theory, literature, geography, and human ecology (for some examples, see Norton, Hutchins, Stevens, Maple 1995, Shrader-Frechette 1984, Gruen and Jamieson (eds.) 1994, Karliner 1997, Diesendorf and Hamilton 1997, Schmidtz and Willott 2002). Many assessments of issues concerned with biodiversity, ecosystem health, poverty, environmental justice and sustainability look at both human and environmental issues, eschewing in the process commitment either to a purely anthropocentric or purely ecocentric perspective (see Hayward and O’Neill 1997, and Dobson 1999 for collections of essays looking at the links between sustainability, justice, welfare and the distribution of environmental goods). The future development of environmental ethics depends on these, and other interdisciplinary synergies, as much as on its anchorage within philosophy (Dereniowska and Matzke 2014).
