有关节约粮食的作文300字左右 急需 谢谢

Many countries in the world are faced with the problems of an increasing population and a shortage of food.

There are a number of possible solutions to the problem, but none of them is easy. Firstly, governments could discourage people from having large families. Why not have just one child?

Secondly, farming methods in those countries are very simple and often inefficient. If the people bought new agricultural machinery, modernized their farming methods and developed more land, they might soon produce enough food for their needs.

Thirdly, many countries have natural resources such as oil, wood or iron. These could be exported so that food could be imported.

All of these possible solutions simplify the problem. But they show that, if people mean to solve the problems of increasing population and food shortages, there are ways of doing it.

粮食，对我们来说是很重要的，没有了粮食，我们就很难生存。
　　现在，因为全球变暖，环境恶化，气候反常，有些地方种的粮食颗粒无收，使到粮食短缺，粮价飞涨，许多穷人因为粮价飞涨而买不起粮食，忍饥挨饿地过着凄惨的生活。粮食已成为世界上的一个大难题。
　　粮食，对人们来说太重要了，节约和爱惜也成为人们的话题了。
　　记得小时候，幼儿园的老师就教我们唱“谁知盘中餐，粒粒皆辛苦”之类节约粮食的儿歌，教育我们珍惜每一粒粮食，不要浪费；妈妈也做了榜样，她在洗米时总是很小心地淘米，把掉落的米粒小心翼翼地捡起来放进锅里。这使我懂得了爱惜粮食。
　　在小学的语文课上，老师要求我们用“来之不易”造句，我毫不犹豫地写上：“我们要珍惜农民伯伯种的来之不易的粮食。”老师在我的句子上打了一个鲜红的勾。
　　但是，我也发现有不少浪费粮食的现象：在学校吃午餐的同学不是很多，可是总能发现白花花的米饭到在垃圾桶里；在餐厅里，一些人的饭菜点了一大堆，吃不完就到倒掉了，这样既花钱又浪费粮食。这些现象真令人痛心。
　　为了节约粮食，我和爸爸妈妈也付出了很大的努力：我每顿饭都把碗里的饭粒扒的干干净净；在外面吃饭，爸爸妈妈从不铺张浪费，能吃多少点多少。有一次，妈妈看我吃得这么干净，便半开玩笑地说：“今天儿子的碗可以不用洗了。”我听了，心里美滋滋的。
　　我们一定要爱惜粮食，不要浪费粮食，因为糟蹋粮食就是糟蹋农民伯伯的心血，浪费粮食就是浪费农民伯伯的劳动成果。
　　啊！只要人人都节约粮食，保护生态环境，爱护地球资源，我相信，这个世界就会变得更加美好！
