What is the big story of our age? It depends on the day, but if we count by centuries, then surely humanity's urbanization is a strong contender. Today, more than half of the world's population lives in cities, compared to less than 3 percent in 1800. By 2025, China alone is expected to have 15 "mega-cities," each with a population of at least 25 million.
