- "UN-Habitat says that a staggering 95 percent of the expected global population growth we will see over the next 2 decades will be absorbed by cities in the developing world... What that means is by 2030 another 2 billion people from the developing world will be living in cities (only 100 million from the developed world meanwhile will be doing the same). Currently 75 percent of world's poorest people -- 1 billion -- live in cities."
- "Already, 75 percent of the world's 21 mega-cities are based in the developing world, and by some estimates, 27 of the 33 mega-cities expected to exist by 2015 will be in developing countries."
- "Cities have always traditionally been the centers of the world's wealth, and the World Bank says that as much as 80 percent of the future economic growth of the developing world will come from its cities."
- "In the next 30 years, China alone will have around 752 million urbanites, all needing to get around town. Currently, less than 1 percent of Chinese own a car... If each of those 752 million city dwellers copied the transportation habits of your average resident of San Francisco in 1990, the actions of that one country would result in 1 billion additional tons of carbon emissions a year -- the same amount that was released worldwide by all road transport in 1998."
