The concept emerged in recent decades as an important framing concept for a wide variety of environmental movements and objectives, and has gained considerable currency due to the scope and normative force that its principles contain, whether in legal, political, or philosophical applications. This collection is an invaluable resource for researchers and scholars in this field given that the multiple theories and analyses of environmental justice are likely to remain central to the ongoing development of normative theorizing about the human role in the environment in the foreseeable future.
