A few days before, I saw an interesting program on TV. It was about the problem of the traffic in our cities. It seemed that a great deal of damage had done by traffic. But now our cities are still suffered from riffs problem. Some buildings are actually falling to piece. It is often faster to walk than to go by car or bus, The problem has been getting worse for long time. This is only one problem among thousands others in our cities. All sorts of terrible things have happened with our cities. And the biggest question is “What can we do about it?” Our roads have ever been designed for such a heavy traffic.
