Twitter Chat: Talk to the man who’s walking around the world

Pulitzer Prize-winning journalist and National Geographic Fellow Paul Salopek is retracing the path of our ancestors’ migration by embarking on a 21,000-mile trek from Africa to Patagonia. The journey, dubbed “Out of Eden Walk,” began in January 2013 in Ethiopia and will end after seven years at the tip of South America.

Hari Sreenivasan spoke to Paul Salopek just before his journey began, in December 2012.

PBS NewsHour Weekend anchor Hari Sreenivasan and a NewsHour crew traveled to Georgia to meet with Salopek and join him for a portion of his walk. See Part 1 and Part 2 of his fascinating journey, and see a recap of a Twitter chat with Paul (@PaulSalopek) below:
