Book excerpt: Red-Green Revolution is a comprehensive introduction to ecosocialism. Moving from an overview of capital's relationship to the environment and a critique of "green capitalism," to a discussion of the divisions within the socialist and environmental movements, Victor Wallis shows how a class-based analysis of technology and society can reshape our relationship with the natural environment. Confronting the planetary emergency brought about by accelerated ecological devastation in the last half-century, Wallis argues that sound ecological policy requires a socialist framework based on democratic participation and examines how such a framework can materialize as popular struggles converge under conditions of crisis. This second edition includes updated references, a new Preface, and an Epilogue in which the author discusses the transformative developments that have occurred since 2018.
