　　Increasing the price of petrol is the best way to solve traffic and pollution.

　　What extend do you agree or disagree? What other measures do you

　　think more effective?

　　Bad traffic and increasing pollution are thorny issues challenging every major

　　city in the globe. To combat such problems, government encourages

　　companies to mark up gas price in an effort to decrease car use and cut down

　　waste gas. However it may temporarily alleviate the problem, but is doubtfully

　　the optimal solution.

　　First of all, consumers and economy would be victimized by such measures.

　　The number of cars in a country directly depends on the proportion of the

　　population affluent enough to own cars. As a result, raises in gas price could

　　invoke hard feelings among this segment of people but would not drastically

　　change their behavior in using cars. Even if the number of cars on road is

　　reduced due to higher gas cost, this is not the best way to solve traffic

　　problems. Such policy would hurt the auto industry, place higher costs on

　　current and prospect car owners, and undermine the economy of a nation. In

　　the long run, the final way out could be the construction of better roads and

　　more effective use of available transport facilities.

　　Secondly, there is evidence that waste gas from cars is not the leading cause

　　of air pollution. The culprit may be the discharge of polluting substances into

　　the atmosphere due to the rapidly growing manufacturing industry. As a result,

　　reduction of the number of cars would not return us a blue sky and fresh air.

　　We could better handle this problem if we could increase control over industrial

　　waste discharge and adopt more environmental friendly materials and

　　production equipment.

　　Finally, other measures like the application of cheaper and cleaner energy

　　resources could also be a better solution. For example, we now have the ability

　　to make cell-powered or even solar-powered cars. Such energy is completely

　　clean and plentiful. However we still have a very long way to go to turn such

　　technologically possible into affordable and practical products.

　　To conclude, it is not the best way to control traffic and pollution by increasing

　　gas price because such action will hurt consumers and economy without

　　achieving what it is aimed for. Measures such as construction of better

　　transport facilities and development of new energy resources could be more

　　effective solutions.
