With the development of society and an increase of population, more and more countries suffer from traffic jams and air pollution. Some people propose that we can address the issue efficiently regards to the transportation and environmental disruption via raising petrol.

Rise prices generally affect the demand of people. As for ordinary people, most of them tend to choose less dependent products of gas. For instance, they prefer to use electrical or solar products, which are more environmentally-friendly, to maintain their daily life. It implies the environment may be improved. In addition, citizens are likely to use public transportation other than private cars for the sake of reducing the living costs. As a result，traffic pressure will be relieved to a great extent.

There are some opposite influences caused by the price increase. Triggered by escalating petrol cost, such as food, clothes and so on, a series of other commodities rise. In terms of this, the low-income group may be more vulnerable than the high-earning people. The gap between the rich and the poor will be widened. The increase in poverty and crime lead to social instability.

The solution to traffic jams and pollution issue is various. The government can do some publicity work to encourage the use of public transportation rather than private cars. The odd-and-even license plate rule should be taken to reduce the number of vehicles. Both reasonable urban traffic planning and the development of renewable energy may contribute to tackle these problems.

In conclusion, I think the rise of petrol may partly help to solve them and simultaneously, give rise to advent effects regarding traffic congestion and air pollution.
