Biofuel Today, I learned Biofuel. Biofuel is made from some materials, such as corn and wheat straw, and other recycle resources. It plays an important rule in the development of our countries. With the increasing requirements from life, the energy use is becoming a big problem, since it will pollute our environment. How to use the energy is now a fatal problem, which we should take into consideration deliberately. How do you think the Biofuel use in the developed countries and developing countries? In my perspective, when a country wants to develop quickly, the government must increase their production volume to improve the economic. Then the energy use will be increased at the same time. For example, they need to build many power plants, and chemical factories, Then the energy over using is inevitable, and the environment will be polluted seriously. After the country Is developed, the government begins to adjust the policies, and reduces the air pollution by inventing more high-tech machines to deal with the waste water and exhaust gas. They even spend a lot of money to save the environment. Maybe it's too late to save it, and it becomes more expensive. The later we trying to save the environment, the more money we paid for it. If we knew the result when we developed our countries, I believe we would take care of our environment carefully. Now there are still a lot of countries polluting our air seriously to make their country wealthy. I hope they put the environment in the first place, after all, lift is the most important, then the money.
