We hear about the three lives of Ping Fu. Beginning life as an orphan, she became a Chinese political prisoner, then relaunched as a pioneer of the high-tech revolution. Today one of America's top business entrepreneurs and an advisor to President Obama, the founder of the 3D printing firm, Geomagic reveals her remarkable life story, and life-lessons. Plus we hear a report from Mumbai on why India street vendors are shouting louder than usual these days, and enjoying it while it lasts. Plus Peter Baker of the non-profit organisation, CABI, that advises farmers in the developing world, explains why climate change may be affecting the world's coffee crop, and why a cup of coffee may end up tasting rather different in the future.
