Change of the Oil Price

Oil is necessary for people. So I should watch and check the oil price when I pass the gas stations. Sometimes it makes me nervous, because oil price is different every week. What is happening in the world now? Oil is a valuable resource for each country. Rarely do oil resources cause wars among the countries, because the oil price closely relates to economic power. Recently higher price of oil causes an uncomfortable situation for people. It is a global problem now. So I should be concerned and need a solution about the oil price. I try to decrease driving in wasteful cases and if I have to travel, I will use a more direct road.
