High school science educator Jay Vavra helped his San Diego students save endangered species in Africa by using simple genetic identification technologies in local African bush meat markets. Nonprofit leader Shannon Horst employs holistic rangeland management techniques to stop the spread of deserts in Africa, the U.S. and worldwide. What's spreading fastest is hope.
