This document discusses using large-scale environmental restoration to combat global warming by putting carbon back into soils through natural processes. It argues that restoring forests, agriculture, grasslands and degraded lands can store carbon while providing sustainable energy and food. Specifically, the document advocates enhancing natural carbon sinks like soils to safely reduce atmospheric CO2 levels to 260 ppm through restoring ecosystems, which is the best solution and can be done quickly through decentralized grassroots efforts.
