With issues such as environmental degradation, climate change, and mass extinction looming, a growing coalition of activists, policymakers, lawyers, scholars, and everyday people are calling for the Rights of Nature to be legally recognized in order to create systemic changes in environmental policy. This thesis traces the history of the Rights of Nature movement, examining key developments around the world and analyzing the historical and ethical underpinnings of these provisions, and how the Rights of Nature can be applied to the Endangered Species Act in the United States. Evoking the language of legal rights has pragmatic value in U.S. environmental policy, explicitly stating the non-anthropocentric position of intrinsic value of nature in an effort to push for a broader value shift within a predominantly anthropocentric legal system.
