Why we should save petrol in our daily life?

Saving petrol in our daily life has become very essential for us. The natural resources wasn’t be used and exploited reasonable and effectively, petrol will be less and less. What’s more, petrol is the nonrenewable resource which will be run out someday in the future. So we should save petrol in our daily life. It costs 2 hundred million of years for the nature to form the crude oil which is below the earth’s surface. But human can consume half of it for only 200 years. USDOE said, if current consumption rate continues, the rest global oil resources will be run out in 40 years. In the consumption of global crude oil, approximately 60% was used for transport vehicle, half of which was used for coach and light truck. Therefore, our cars burn less gasoline will affect oil consumption. Perhaps more importantly, saving petrol will affect the oil demand. Air pollution is a global problem, and the United States is the largest green house gas emission country which is 20% of the total. Reduce the demand of import crude oil will reduce oil leakage and improve water pollution. Global warming is also concerned with the automobile exhaust emissions. Greenhouse gases will prevent a significant proportion of the infrared radiation scattered overflows into space, make heat release out, thus speeding up the speed of global warming. In short, when you save petrol, it not only save your money but also make a contribution to the environment protection.
