I do not support the idea that the only way to the environment conservation is increasing the price of the fuel. While the increasing price can be seen as an efficient way to reduce the usage of fuel in the current time, it does solve the basic problem: how can people survive with the minimum contamination. To that point, the decrease of using automobile, as well as the large using of renewable resource, is necessary.
The air contamination caused by automobile determines that people have to quit using cars. In the United States, the average passenger car emits 5 tones of carbon dioxide, along with smaller amounts of hydrocarbons and nitrogen. To be more exact, carbon dioxide, to a large extend, is blamed for contributing to global warming, which is one of the most concerning environment problems around the world recently. Therefore, instead of increasing the price of the fuel, it is an emergency to control the total number of private vehicle, thereafter reduce this amount. In addition, the unhealthy air we breathe results from those gases. Study shows that the air quality in dozens of metropolitan areas has worsened over the last decade and keeping becoming worse. Consequently, people will tend to use more environmental ways to travel, such as public transportations and bikes.
Apart from the decrease usage of vehicles, the increase using of renewable resource is another solution of the contamination. Due to the severe environment crisis, this industry is regarded both promising and profitable. The policy of government inclines to develop new clean energy source in order to deal with lack of traditional resource and environmental damage. Companies in this field, therefore, are more likely to get both financial and technical aid from the authority, which means they have leverage over the traditional fuels companies and have more chance to survive in the power-market. Furthermore, the public barely criticize it because of its “green color”. Consumers with high education and awareness of the environment are even likely to purchase the product related by renewable energy, no matter what the price is. As a result, the development of renewable resource will be rapid, making the source of contamination reduce dramatically.
In short, price is not always the most useful weapon. In this case, it is efficient to be an addition but a major factor. Still, the arch point is that measures should be taken immediately, or else it would be too late.
