This is Scientific America's 60-Second Science, I am Karen Hopkin. This will just take a minute.

Most of us don’t think twice about getting behind the wheel even for short hops¹ to pick up some milk. And that’s not just because cars are convenient, or because we’re lazy. According to Andrew Furman of Ryerson University in Toronto, it’s because in many places in North America it’s just not that nice to walk. But if cities and suburbs put more effort into building better pedestrian routes, he says more people might leave their SUVs at home.

With its older cities, Europe is more amenable² to meandering³. Think cobblestone streets and hidden gardens. But North American cities and suburbs are more modern and car-centric, which generally forces pedestrians⁴ and cyclists to always take the same, boring path from A to B. But what if you could take a detour⁵ through a lobby that exhibits art, or down a lane that borders a green space? Furman thinks you’d be more likely to hoof⁶ it, which would be good for you and for the environment.

Take New York City’s High Line, an abandoned railroad that’s been converted into a public park. Since its opening a year ago, this elevated walkway has people strolling through the meatpacking district. Even for folks who like to walk, that’s quite a feat⁷.

Thanks for the minute for Scientific America's 60-Second Science. I am Karen Hopkin.
