My opinion about riding bicycle

Riding bicycle become a popular exercise in recent year. Why this activities can accepted by people?

There are many reasons for this question. First of all, the hight price of gas. Because of the among of crude oil in the world is cut down gradually, so the price is increasing. Most of the transportation mechine can not start without gas. After that, a lot of people start to ride the bicycle. Second, because of enviroment. The greenhouse effect is become serious during recent years. It was due to greenhouse effect that we can heard many people die from baking-hot weather. To cut down the carbon dioxide is essentially. If you care about our enviroment, riding bike is your best choice that can reduce the air pollution. Third, the inflation. Because of economy depressed, many people need to earn more money. The transportation cost a lot of their money, so they decide to ride the bike.

Riding bicycle is not only for exercising but also can save your money and save our enviroment. I think many students in the university have not rode the bicycle for long time ago. Maybe you can find out again your bicycle from stockroom, and try to ride your bicycle to school.
