Felix Finkbeiner's stringbean physique is complemented by a pair of wire-rimmed glasses and a pudding-bowl haircut. At 13, he is an environmental superstar at the helm of a global network of child activists whose aim is to mitigate climate change by reforesting the planet. Behind his apparently unprepossessing facade, Felix is really an action hero. His organisation, Plant for the Planet, recently achieved its target of planting one million trees in Germany; now, Felix is spreading his message around the world. Plant for the Planet is up and running in 131 countries.
