There is no getting around the fact that traffic congestion and pollution problems, which have been presented to us for long, are increasingly severe. Increasing the price of petrol is a less efficient method that can hardly tackle the problems, thoroughly.

It is undeniable that the large amount of private cars is the main cause of traffic jams and car emissions. Probably, raising the price of petrol would decrease the number of using the private cars. But it is not the sustainable way. As higher petrol costs will raise the cost of all kinds of vehicle as well, including public transportation. What it is meant by this is that individuals have to pay more money on travelling, which contributes the larger economic pressures to the poor families. Furthermore, increasing the price of petrol is harmful for the agriculture. Because farmers cultivate crops by modern machines which run by petrol. If the price of fuel gets higher, farmers would have to spend more money on farming. And the price of farm produces would be raised as well.

In terms of traffic problems, carpooling is one of the most effective ways. This way is becoming more and more popular among the young people. People can share cars with others when they go out, so the numbers of cars on the roads can be reduced. In addition, there is a tendency that cleaner fuels are being developed in the vehicle. For instance, electric motorcycles are being used among many people. This kind of vehicle does not have car emissions which contaminates the air condition.

Nobody can shirk his or her responsibility for environment protection. What people should do is reducing the times of using private cars and harnessing cleaner energy power.
