The fast increase in the number of cars have broughtalong many related problems which are well worthour greatest attention.

   First of all, urban traffic is getting from bad to worse. I’d like to cite my own experience as anexample. Five years ago, it took me about 30 minutes to drive from home to office. One yearlater, I needed to spend about 40 minutes on the way. Then two years later, I had to start outfrom home at least 1 hour earlier in order to get to my office on good time for work. And then,since last year, it has just been too normal for me to spend about one and half hours to makeit. The traffic just moves like a worm!

   Second, with the ever growing number of cars, air quality in urban areas is deteriorating witheach passing day. We used to see clear blue sky and breathe fresh air, but now this would be areal luxury. Car exhaust has seriously polluted the air and people’s health is greatlyendangered. It seems certain that we human beings have already made a fatal mistake thatcould only be remedied by bringing down the number of cars hugely.

   Sure, we can not deny the fact that cars have brought us speed, comfort and greatermobility. However, these have already been history. We are suffering much more from carsthan benefiting from them. Our health conditions are going down rapidly both due to thepolluted air that we have to breathe every second and our lack of exercise as a result of theever increasing amount of time we have to spend behind the wheel!

   What can we do? From the foregoing discussion, I’m sure we have already found a solution: todiscourage people to use cars! I know very well that science and technology are alsodeveloping very fast and there might be better solutions coming up in the future, but, beforethat, let’s first salvage ourselves in such a passive way!
