Oil price

Today I watch the news a related story of oil price. These days oil price had been steadily soaring since a few months ago. Actually these days oil price fluctuate very widely.That is to say; one day  oil price to be lowed and the other day oil price soared.Beside oil price vary in different localities and vary in different filling service station.Well then why this phenomenon occuring? Frankely I don’t know.Anyway nowadays oil price is very expensive.So common people feel a heavy burden on a their domestic economy. In this case the goverment don’t have to impose severely heavy tax burden to common people.Also the general public and the rich are should take advantage of the public transportation.Because the public transportation fare is commonly cheap and we can quickly arrived at our destination particularly during in the rush hours.Above all the rest subway transportation is efficient.
