There is no denying the fact that the traffic and pollution are a global issue that affact human in several ways. While it is held belief that increasing the cost of petrol could solve the proplem, there is an argument opposes it. In my opinion, I consider that the problem is begier than higher the cost, it is about feel how serios the problem is, but it will reduse the uasege of petrol withn tiny amount that will be unnoticable.
