SPECIAL: Transportation around the world

In this one-hour special, The World looks at transportation issues around the globe. Thor Pedersen, a former UN soldier originally from Denmark, went on a decadelong adventure that took him to every country in the world. The trick — he never took an airplane. And, NASA’s Artemis program aims to bring the first woman and first person of color to the moon in 2024, and it's the prelude to a much bigger ambition — sending humans to Mars. Also, lithium is in soaring global demand, because it's used in electric car batteries. This is good news for the economy of Chile, that meets a third of the world’s lithium needs. Plus, a Finnish driver gets a $120,000 speeding ticket.
