This volume illustrates Asian speculative fiction's potential to interrogate and inspire humanity's ecological and ethical responsibilities, seeking to fill a major lacuna in previous academic literature around ecocriticism in speculative fiction. Contributions are thematically organized into three sections—Human-Nature Co-evolution and Ecomedia, Technologies and East Asian Heritage, and Posthuman Ecology. Chapter authors draw on global viewpoints to provide a multi-dimensional analysis that includes Indigenous knowledge, trans-local (inter-Asian) exchanges, and perspectives from the Global South. To end, the book provides a reflection on how speculative fiction promotes a vision of interconnected kinship among humans, the nonhuman, and the natural world.
