Given the many environmental crises facing the planet, we need to use all tools to address them, including Shakespearean theatre. This Element explains why Shakespeare is well-positioned to be an eco-playwright, how theatre-makers can adapt his plays to matter now, and how to make more ecological the many processes of Shakespearean theatre, from set design to performing outdoors. The co-authors are both directors, and conversations between them about their recent eco-productions of The Tempest for the Royal Shakespeare Company and A Midsummer Night's Dream for Shakespeare in Yosemite (California) give clear examples of both the why and how of eco-theatrical Shakespeare.
