    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.
