Paul Salopek is a Pulitzer-prize winning journalist and National Geographic fellow who is walking from Africa to South America, the original human migration trail. He is three years into a trek which may take almost a decade. He says his main mission is not walking but storytelling. He started off in Ethiopia, has just walked through Azerbaijan and is now heading into Central Asia via Kazakhstan. He spoke to Weekend's Julian Worricker about the task he has taken on.
