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，which has worsened the severe situation. How can we 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. If the whole world works together，I think more food will be produced and we can create a harmonious world. struggle vt. 搏斗；斗争；努力；挣扎 n．斗争；挣扎 struggle with/against 与……搏斗/斗争struggle for sth./to do sth. 努力/争取…… struggle to one‘s feet 挣扎着站起来with a struggle 费劲地 |
