关于气象与水的作文【一】
古人语：“地力之生物有大数，人力这成物有大限，取之有度，用之有节，则常足，取之无度，用之不节，则常不足。”这句话的意思是：自然界所生长的万物（资源）是有限的，由人来加工制成的物品资源也有限。而取时有限度，用时节约，则常常能满足人类的需求。如果相反，取时无限度，用时又浪费，那么球上公有的资源就会很快消失。

关于气象与水的作文【四】
现在全社会最引人注目的事是节约，节约是时下最热门的话题（next88）。新闻媒体每天都有关于节约的报道，茶余饭后人们也在谈论着这个话题。人们对于节约众说纷纭，观点不一，煞是热闹！（议论文）
同学们不是经常在书中读到中国地大物博，物产丰富吗？那么，我们为什么还要节约呢？因为我国是一个有13亿人口的泱泱大国，自然资源比较匮乏。就拿水资源来说吧：人类用水量随着人口的增长而不断增加，世界人口，在50年代为25亿，1999年达到了60亿，增加1.4倍，与此同时，农业用水增加了5倍，工业用水增加了26倍，家庭及生活用水增加了18倍，据专家估计，世界人口正以每年8100万的速度递增，预计到2050年将达到94亿，水的需求量也将成倍增长，形式十分严峻。
拧开水龙头，清洁甘冽的水滚滚而来，其实，自来水来之不易。它们可能取自几百米深的地下，或者引自几十公里、几百公里远的某条江河，某座水库，这些原水首先要在净水厂净化，去除铁质，去除细小的漂浮物，水生物，沉淀下杂质，用***菌液体***菌，经过检验符合人体饮用后才能出厂。合格的自来水经过蜘蛛网似的管道，用高压水泵加压，才能源源不断地送入居民家。大家看，每一滴自来水都要经过那么多的程序，你有理由浪费吗？
近几年来，由于人们生活水平的提高，大家对艰苦奋斗和勤俭节约地意识淡薄，大吃大喝，铺张浪费现象比比皆是。而且人们普遍出现了认识上的误区，很多人认为节约就是小气，以为生活水平提高了，就该讲阔气，讲派头，讲排场。中国人民自古以来长期形成的俭朴的作风早已忘得一干二净。即使有的人想节约，但是碍于面子，也充当大款。节约为荣，浪费可耻变成了浪费为荣，节约为耻了。
