Cities are remarkably resilient and the vast majority persist. Just think of the awful experiment that was done seventy years ago when atom bombs were
dropped on two cities, yet just thirty years later they were thriving. It's ex(w tremely difficult to kill a city! On the other hand, it's relatively easy to kill
Panimals and companies-overwhelmingly, almost all of them eventually die, to even the most powerful and seemingly invulnerable.
In 2006 the planet crossed a remarkable historical threshold, with more than half of the world's population residing in urban centers, compared with just 15 percent a hundred years ago and still only 30 percent by 1950. It is now expected to rise above 75 percent by 2050, with more than two billion more people moving to cities, mostly in China, India, Southeast Asia, and Africa.

SOCIOECONOMIC URBANIZED WORLD
A central topic of the book is the critical role that cities and global urbaniza tion play in determining the future of the planet. Cities have emerged as the source of the greatest challenges the planet has faced since humans became social.
The existence of these remarkable regularities strongly suggests that there is a common conceptual framework underlying all of these very different highly complex phenomena and that the dynamics, growth, and organization of animals, plants, human social behavior, cities, and companies are, in fact, subject to similar generic “laws."
could possibly be any analogous hidden order underlying all of this complexity and diversity. Could there conceivably be a few simple rules that all organisms obey, indeed all complex systems, from plants and animals to cities and companies? Or is all of the drama being played out in the forests, savannahs, and cities across the globe arbitrary and capricious, just one haphazard event after another
