This Companion offers a comprehensive and accessible introduction to the environmental humanities, an interdisciplinary movement that responds to a world reconfigured by climate change and its effects, from environmental racism and global migration to resource impoverishment and the importance of the nonhuman world. It addresses the twenty-first century recognition of an environmental crisis – its antecedents, current forms, and future trajectories – as well as possible responses to it. This books foregrounds scholarship from different periods, fields, and global locations, but it is organized to give readers a working context for the foundational debates. Each chapter examines a key topic or theme in Environmental Humanities, shows why that topic emerged as a category of study, explores the different approaches to the topics, suggests future avenues of inquiry, and considers the topic's global implications, especially those that involve environmental justice issues.
