"Building a society that operates within ecological constraints requires an unleashing of our political imaginations, and this book helps us do just that." Astra Taylor, author of The Age of Insecurity Half-Earth Socialism is a radical call to action to save the planet, including trenchant proposals to rewild half the earth to absorb carbon emissions and restore biodiversity; rapidly transition to renewable energy, paired with drastic cuts in consumption; and shift to global veganism to radically reduce energy and land use. As this thrilling and provocative book makes clear, we must humbly accept that humanity cannot fully understand or control the earth --but we can plan new energy systems, large-scale rewilding, and food production for the common good. "Conclusively demonstrates how a livable future requires a fundamentally different relationship to the earth, the only home our species has ever known. A must-read for post-capitalists and those who care about the climate crisis." Aaron Bastani, author of Fully Automated Luxury Communism "Read this book if you not only dream of saving the world but want a plan for how to do it."
