As you know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation. Then what should we do to deal with the problem? On the one hand, we should focus on the environmental protection and improve the ecology. On the other hand, strict measures should be taken to protect farmland. Of course, to build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage. As for me, I will call on the people around me to take immediate action. And for the moment, I think, we should put our heart into our own studies to get more scientific knowledge and help solve the food shortage in the future. 1．unrest n. 动荡；动乱　　　　　 2.urbanization n. 城市化 3．on behalf of 代表 4.due to 由于　 1．Match the main idea with each part.
