Some bold researchers pinned down this epochal moment of passage to May 23, 2007. The date was of course a polite statistical fiction, based on a United Nations estimate of how fast people worldwide are shaking off the dust of the countryside and moving into town.
In any case, nobody stood up to ask the important question: What does it mean to become a city-dwelling species?

In the public housing projects of Chicago, for instance, studies have consistently shown that trees make for healthier neighborhoods, with more people spending time outdoors and more kids playing in creative ways. Housing projects with trees also have about 7 percent less crime than their treeless counterparts.
You wouldn't use a word like "sylvan" about any of these neighborhoods. They're still just public housing projects.

Open-heart patients in rooms with nature scenes on the wall have lower blood pressure and smoother recoveries than patients with blank walls or abstract art. ...
