To many people,crisis is perhaps the last thing to see,so as petrol.Nothing is more important than the fact that petrol is shortage.In general,there are two main reasons leading to the reduce of the petrol.On the one hand,with the development of economy,a great deal of energy in needed to run the factories of China.Automobiles,trains,planes,and buses need energy,to.Nearly all of this energy is petrol.On the other hand is waster.
As far as I am concerned,the petrol is limit,but our need for petrol is increasing rapidly-almost day by day.Only if we take step to find or invent new filue to substitute petrol.Automobile manufacturers are working on experimental cars run by electricity or other means that will reduce petrol and they are quite successful.
Therefore,I think it is really high time that we considered how to save petrol.We all have to learn how to stop wasting our precious petrol.
