1.In the recent years,the global grain has been under tense situation.Especially since the second half of 2007,grain crisis has occurred in many areas in the world and continued to spread rapidly.
2.As the sharp decline of global grain reserves,the price of main grains keeps increasing.
3.Most countries in the world have been affected to different extent.The high price of grain even resulted in conflicts and riots in some countries in Africa,Asia and Latin America.
4.In my opinion,increasing population,reduction in lands,climate damage and updating food structure are the causes of global grain crisis.
