On Lange‘s Conjecture

Nowadays, it is generally acknowledged that the automobiles make our life convenient.Some argue that they play an essential role in our modern life and we can not live well without automobiles.People drive their cars to go to work which saves more time and energy.

But some other people believe that a great many of problems can be brought by the automobiles. First of all, much tail gas released by cars harm pollutes the fresh air gravely. Secondly, too many cars result the roads in blocked. Finally, fast driving makes people crazy, which can account for so many traffic accidents.

As far as I concerned, it is no doubt that vehicles contribute to our economic development exceedingly. But if we overuse it, many undesirable consequences can be surely caused, which contains highway accidents, air pollution and so on. So at this moment, we must take measures to avoid these happen.

Speaking of bicycle, some people think it has outdated in many big cities. However, some people think that it is still popular for them because people can exercise themselves by riding bicycle. For me, I think people can get lots of benefits from riding bicycles.

Secondly, bicycle is good for our environment. In almost all big cities, the average temperature is a bit higher than countryside for there are too many car emissions there. We all know that people in big cities like to drive cars to go to work rather than taking public transportations. Therefore, our environment is polluted by lots of emissions. If more people join in the trend to ride bicycles to work, then our air quality will be improved obviously.

In conclusion, riding bicycle not only can make us healthier but also it is good for protecting our environment. So, we should encourage more people to ride bicycles quite often than driving cars.
