The science is clear: by the mid-20th century human beings must stop burning coal, oil and natural gas. Reducing carbon emissions is not enough—they must be eliminated. Each individual "doing their part" is only a start. We heat our homes, light our rooms, power our cars, prepare our food, and produce and distribute consumer goods with the help of fossil fuels. A practical and visionary re-imagining of the future is needed. Calling for a technical and spiritual ground-shift, this book proposes carbon boycotts as collective action, with groups and communities changing what products they consume and seeking new ways to work, live and play to steer aggregate demand towards solar, wind, geothermal and renewable energy alternatives.
