Food Shortage
As we know，food shortage has hit many countries and even caused social unrest in some areas. But what has caused the current world food crisis？Firstly，annual world grain output had declined because of climate changes. 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(生物燃料)，which has worsened the severe situation.
How can we deal with the problem？On the one hand，we should focus on the environmenta l protection and improve the ecology. On the other hand，strict measures should be taken to protect farmland.
If the whole world works together，I think more food will be produced and we can create a harmonious world.
