China's green hero Yin Yuzhen reunites with her American friend Ronald Sakolsky at World Food Forum in Rome.
26 years ago, while in China on a teaching exchange program, Sakolsky raised 5,000 U.S. dollars to support Yin's tree-planting efforts in a desert.
With the funds, Yin and her family went on to cultivate a forest of more than 50,000 trees.
