The bustling city streets of Barcelona seem as good a place as any to mark World Population Day. More and more of us are heading to the city. It"s estimated that 2007 was the first year in which more people lived in cities than in rural areas. If current trends continue, by 2050 about two-thirds of the world population will be living in cities. City planners and government officials will need to account for this rapid increase as power grids, water supplies, public transit, and emergency services will all be stretched.
