Increasing the price of petrol is the best way to solve growing traffic and pollution problems. It is a common thought that if we raised the price of petrol we could reduce road traffic and, therefore, the air pollution. I partly agree with this statement, even though, we must decrease the traffic in the cities. In my opinion, we have to take some important decisions on these huge matters as soon as possible. These days, traffic in our cities is growing and pollution as well. Nevertheless, some people use cars in a careless way. Furthermore, there are countries where it is very difficult breathing, such as China, and also the numbers of death for cancer is increasing because of air pollution. I remember that when I was a young boy people did not link health problem with petrol. Contrarily, today we are more conscious about this problem and I am sure that in the future we will solve this issue. We know that air pollution is a big problem and that cars contribute in its production. But also power plants that give us energy use coal to create electricity and factories produce too much smog as well. Therefore, I agree that we have to decrease the use of cars but I do not think that If we raised the cost of the fuel we could solve this matter. I remember that the Italian government increased the price of petrol some years ago. Nevertheless, people continued to use their cars. In my opinion, we have to reduce pollution in others way, for instance, people could reduce the use of electricity. I think that a right measure could be a targeted advertising on this matter because, in this way, people could become more aware on the problem. In conclusion, we can increase the price of petrol to resolve the road traffic and reduce the air pollution. But power farms and/or factories will continue creating smog. In my opinion, people should be more conscious that we are doing a big environmental damage.
