Pulitzer Prize-winning journalist and storyteller Paul Salopek is traveling the world by foot as part of his project "Out of Eden Walk." He's now in Beijing sharing his travel experiences through the unique form of "slow journalism" he's known for. The journey began in Ethiopia in 2013 and will finish in 2027. Salopek just finished visiting China's south-eastern Yunnan and Sichuan provinces and says he's amazed at the country's biodiversity.
