Celebrated journalist Christophe Doré recounts the unique journeys of these builders, restorers, and inventors who preferred taking action out in the field to appearing on making speeches on talk shows. Take, for example, the female French scientist researching the pollution-fighting powers of plants, the farmer who stopped the desert's advance in Burkina Faso, the man who saved primates by turning Indonesian forests into sanctuaries, or the engineers who restored natural landscapes in China, or even those busy developing tomorrow's renewable energies in Scotland, France, and America!
