It’s Earth Week again, and, more and more, we treat this event as a sort of green New Year’s Day: what changes can I make to benefit the natural environment? For many of us Americans, the answer could be as simple as “take a walk.”
It turns out that Americans walk less than the citizens of any other industrialized nation. Unless we live in dense urban centers, we drive to work, drive to the store, and often even drive to places to, well, take a walk. Despite this being the most natural of activities, we design it out of our daily lives: how many suburban subdivisions have sidewalks, much less stores, restaurants, and other destinations within walking distance. Shoot, we even speed it up when we have to do it: think of the moving walkways in airports.
