Up The Road: Why Travel?

We head up the road this week on a philosophical trip, to answer the question: Why travel? We travel because we’re a migratory species, on the most basic level, and we’ve gotten good at it over the eons. At first, we traveled strictly to survive, as many still do. Now the middle-class travels for fun, as only the upper class once did.

But there is a cost to so much travel. According to a study published in the journal Nature Climate Change earlier this year, tourism—meaning, pleasure travel—accounts for 8 percent of all global greenhouse gases. Some sources put the total closer to 10 percent.
