This beautifully illustrated picture book with finely detailed watercolour paintings tells the story of Wangari Maathai, winner of the 2004 Nobel Peace Prize and inspirational founder of the Green Belt Movement that helped restore trees to the Kenyan landscape which was being devastated by clearance for large-scale farming enterprises. Returning to her native land after studying abroad, Wangari Maathai teaches rural women to combat impoverishment and the erosion of the hillsides by collecting and growing tree seeds and returning their environment to its former richness. This is a simple but powerful story of how one person can help change the world.
