Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming. A chat with Paul Hawken about his ambitious new effort to “map, measure, and model” global warming solutions. vox

Drawdown is based on meticulous research that maps, measures, models, and describes the most substantive solutions to global warming that already exist. It is the most important goal for humanity to undertake. site
