范文 (One possible version)

Hello, everyone,

Now I’ll tell you something about our research project The WorldFood Crisis on behalf of our group. As you know, food shortageshave hit many countries in the world and even caused social unrestin some areas. But who is responsible for the current world foodcrisis? First, annual world grains output has declined because ofclimate change. Then lots of farmland has been lost due to therapid development of industry and urbanization. Besides, faced withthe rising energy prices, people have turned to the production ofbiofuels, which has worsened the severe situation.

Then what should we do to deal with the problem? On one hand, weshould focus on the environmental protection and improve theecology. On the other hand, strict measures should be taken toprotect farmland. Of course, to build a harmonious world thedeveloped countries should take their responsibilities to help thepoor ones experiencing food shortage.

As for me, I will call on the people around me to livethriftily. And for the moment, I think, we should study hard todevelop science and help solve the food shortage in thefuture.
