Cities Can Save the World.
Metropoles - world cities - are lead players in the global economy. Though they cover just 2 percent of the earth’s surface, cities consume 75 percent of the resources utilized by humankind. Cities dominate the planet politically, economically, ecologically and cultur- ally. How mankind functions in the city of the future shall to a large extent depend on factors such as energy, water, waste, food, mobil- ity and ICT. If we manage to make our cities sustainable then this will have a huge impact for the whole of the planet.
