This anthology combines an intercultural approach with intergenerational ethics to address critical environmental challenges. Written by scholars from all over the world, including Canada, the US, New Zealand, Nigeria, Ethiopia, Japan, the UK, China, and Spain, this book offers new perspectives on how to foster sustainable societal practises that draw on the past and are fair to future generations. It introduces the Maori idea that views all things and human generations in layered relations; Indigenous accounts of spiralling time and reciprocities among ancestors and descendants; the philosophical dimensions of Chinese conceptions of ancestor spirits and future ghosts; and African accounts of anamnestic solidarity among generations. These ideas influence proposals for how to confront ending worlds and address the environmental future of humanity, making this book a valuable resource for scholars and students of environmental law and policy, environmental humanities, political science, and intercultural and comparative philosophy, as well as policymakers.
