古话说: 民以食为天。目前, 不少地方土地干旱, 粮食短缺问题依然是急需解决的问题。请以Food Shortage为题, 写一篇120个词左右的英语短文。
要求:1. 介绍现在的饥荒状况
2. 说明其原因
3. 应当采取的措施
Food Shortage
①As 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 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.
How can we deal with the problem?②On 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, more food will be produced and we can create a harmonious world.
