Foregrounding planetary interconnectedness, this Companion presents an accessible, rich survey of theatre's relationship with ecology. Through its clear definitions of complex concepts, it introduces students to key themes, practitioners and performances in the field of environmental performance. To demonstrate the specific ways that theatre makes its unique contributions to pressing ecological debates and dialogues, chapters range widely across Asia, Australia, Africa, the Caribbean, Europe and South America. In keeping with accepted definition of ecology as a science of relation, each of the chapters in the Companion stresses the need to consider environmental, political and aesthetics issues together.
