The American Society of Civil Engineers said in 2007 that the U.S. had fallen so far behind in maintaining its public infrastructure -- roads, bridges, schools, dams -- that it would take more than a trillion and half dollars over five years to bring it back up to standard. Instead, these types of expenditures are being cut back. At the same time, public infrastructure around the world is facing unprecedented stress, with hurricanes, cyclones, floods and forest fires all increasing in frequency and intensity. It's easy to imagine a future in which growing numbers of cities have their frail and long-neglected infrastructures knocked out by disasters and then are left to rot, their core services never repaired or rehabilitated. The well-off, meanwhile, will withdraw into gated communities, their needs met by privatized providers.
