It is asserted that the most optional way to overcome the global environmental challenges is rising the price of fuel. In my opinion, this procedure might have some benefits in terms of reducing the carbon footprint and enhancing air quality across the world due to the shift to the alternative energy resources.

In addition, there is a risk that rich people may not change their habits of using fuel.
