future political map of the world

We don't often question the typical world map that hangs on the walls of classrooms — a patchwork of yellow, pink and green that separates the world into more than 200 nations. But Parag Khanna, a global strategist, says that this map is, essentially, obsolete.Khanna is the author of the new book "Connectography: Mapping the Future of Global Civilization," in which he argues that the arc of global history is undeniably bending toward integration. Instead of the boundaries that separate sovereign nations, the lines that we should put on our maps are the high-speed railways, broadband cables and shipping routes that connect us, he says. And instead of focusing on nation-states, we should focus on the dozens of mega-cities that house most of the world's people and economic growth.
