As I was being driven through Tel Aviv from my hotel to a conference center in 1998, I could not help but note the overwhelming presence of cars and parking lots. It was obvious that Tel Aviv, expanding from a small settlement a half-century ago to a city of some 3 million today, had evolved during the automobile era. It occurred to me that the ratio of parks to parking lots may be the best indicator of the livability of a city—an indication of whether the city is designed for people or for cars.
Tel Aviv is not the world’s only fast-growing city. Urbanization is the second dominant demographic trend of our time, after population growth itself. In 1900, some 150 million people lived in cities. By 2000, it was 2.8 billion people, a 19-fold increase. Now more than half of us live in cities—making humans, for the first time, an urban species.
