The Silk Road and Ancient Trade: In which John Green teaches you about the so-called Silk Road, a network of trade routes where goods such as ivory, silver, iron, wine, and yes, silk were exchanged across the ancient world, from China to the West. Along with all these consumer goods, things like disease and ideas made the trip as well. As is his custom, John ties the Silk Road to modern life, and the ways that we get our stuff today.
