Petroleum Crisis
With the development of society and economy,the world's demand of energy has increase,and petroleum becomes the most important energy in every country.
China has changed a lot and develops very fast recently,both the agriculture and the industry need enough petroleum,our country now faces a difficult problem-----petroleum crisis.
In my opinion,there are two main reasons why our country now short of petroleum,firstly,the supply of petroleum isn't enough,as we know,our country import petroleum from the west of Asia where the output of petroleum sharply decrease now.Secondly,with the development of the industry,the need of petroleum increase,some main industries need petroleum to operation.
I believe petroleum will play a more and more important role in the future
