Adverse effects of motor vehicles

Today, I saw an online news on unusual climate, which refers to the deterioration of environment. Thinking I have just seen on the concept car's introduction, I would like to know if the car is really good for people then? I do not entirely agree with this point of view. First of all, as we know, traffic congestion has long been a problem of great concern and complaint in big cities, such as Shanghai, Beijing and so on. Secondly, traffic accidents have made streets become one of the most dangerous places. According to statistics, over the years because of traffic deaths in China each year is more than 10 million. Last but not least, no one can deny the fact that there are increasingly proportion of people choose to travel or go to work by car, which triggers huge consumption of fuel and severe air and noise contamination.

So in my opinion, we should use public transportation. When we use it, we can help reduce air and traffic jams. And government should take measures to explore environmentally friendly fuel, which is characteristic of high-tech content, high additional value and low energy consumption.
