Even the simplest is so complex that the largest computer cannot fully unravel

What cities sorely need is a systems approach to pollution: a computer analysis of everything that a total environment-greater Los Angeles, for example-is taking in and giving out via air, land, water. Only then can cities make cost-benefit choices and balance the system. Equally vital are economic incentives, such as taxing specific pollutants so that factories stop using them.
