如今世界糧食短缺，糧價(jià)飛漲，甚至致使部分地區(qū)發(fā)生動(dòng)亂．假設(shè)在你校開(kāi)展的研究性學(xué)習(xí)中，你們小組以"The World Food Crisis"為題進(jìn)行研究，現(xiàn)在請(qǐng)你代表你們小組向全體同學(xué)簡(jiǎn)要介紹你們的研究成果．主要內(nèi)容如下：

Hello，everyone，
Now I'll tell you something about our research project"The World Food Crisis"on behalf of our group．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 grain 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 biofuel，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 help the poor ones．As for me，I will call on the people around me to live thriftily．And for the moment，we should study hard to develop science and help solve the problem of food shortages in the future
