Here is a preview to NewsHour’s Wednesday night broadcast. For Paul Salopek’s answers to viewers’ questions, check out this video.

Two-time Pulitzer Prize-winning foreign correspondent Paul Salopek is about to set off on one of the most ambitious reporting assignments ever attempted. In January, he’ll strap a small rucksack to his back and begin walking some 21,000 miles, through deserts and tundras, across rainforests and cities, tracing the ancient path of human migration around the globe.

The 30-million-step journey, funded by National Geographic and the Knight Foundation, will take an estimated seven years and countless pairs of shoes to complete. But thanks to the Web and a slew of compact gadgets, millions of people will be able to follow along, gaining ground-level insight into some of the most pressing issues of our time.

In anticipation of his departure, Hari Sreenivasan sat down with Salopek to unpack some of the details of the trip.
