Food Shortage [总述主题]①As we know, food shortage has hit many countries and even caused social unrest in some areas. [说明原因]But what has caused the current world food crisis? Firstly, annual world grain output has declined because of climate change. Secondly, lots of farmland has given way to factories and buildings due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, some people use grain for biofuel, which has worsened the severe situation.

[具体措施]How can we deal with the problem? ② 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. [展望未来]If the whole world works together, more food will be produced and we can create a harmonious world.
