It is an undeniable fact that global warming is becoming worse and worse by negative effects of traffic and pollution problems. There are those who argue that the most effective approach to address the previously mentioned issues is to increase the price of gasoline. From of my view, this may be have a few benefit. However, personally, I partly oppose the notion of altering the price of gasoline, and I firmly hold the belief that there exist alternative and efficient approaches to address the issues at hand.
