小学三年级作文：保护环境
在我们的身边就有很多污染环境的污染物，比如说：大量的生活废弃品、废塑袋、一次性饭盒、果皮纸屑等等。污染物对环境来说，毫无疑问，肯定有很大的危害。
就拿我们学校来说吧，学校里有些学生经常乱扔果皮、纸屑，不仅影响了环境，更糟糕的是别人一不小心踩到了，就有可能滑倒;在班里，有些同学的椅子上还有些瓜子壳、铅笔屑。还有爱吃糖的同学经常往地上吐泡泡糖，别人要是踩上，粘在脚底下取不掉多伤情绪啊。还有些调皮的同学，用蜡笔在门上和墙壁上乱写乱画，破坏了教室的清洁。
像上面所说的那样破坏环境的人和事，真是举不胜举。我真想对人类说：“保护环境，人人有责。”让我们从现在做起，从自己做起，从小事做起，爱护我们身边的一草一木，为保护环境建设我们美好的的家园作出自己的贡献。
环保作文400字：保护地球环境
地球只有一个，是我们赖以生存的家园，但是在工业革命之后，我们的地球母亲便失去了它原有的光彩，变得黯淡了;变得憔悴了;变得不堪重负了。
水资源是宝贵的，但是浪费水的情景是随处可见的，难

有人经常说爱护环境人人有责，但是真真实实的付诸行动的，真真实实去办的屈指可数，难道我们只会空口说大话，不会真真为之努力的?我想每个人多会说：“不!”因为我们人类是世界上最高等的动物。我们有能力去改变地球，但是在建设我们自己家园的同时，我们也在破坏着我们唯一的家园。
现阶段，人类科技的快速发展，为人类创造了大量的物质财富和精神财富。但是有没有人想过，我们拥有了这些物质和经济财富却失去了我们赖以生存的唯一家园。
小学三年级作文：环保从我做起
保护环境，就是保护人类生存的环境，使地球不受到污染。环保意识，从我做起，从点点滴滴做起，从一张小纸屑开始做起。
环保写起来是非常简单的，但做起来却非常困难。在我们的生活中，有多少人是真正做到环保的？现在许许多多的地方都发生了地震，水灾，干旱，沙尘暴，可以说是灾难连连。这些自然灾害其实都是我们人类一手造成的。比如：我们人类每天乱砍伐树木，但却不知道种树，森林一天天减少，

其实我觉得环保不光是大人的事，也是我们小学生应尽的责任和义务。其实，绿化家园，保护生态，不是一件遥不可及的壮举。环保，只需从自己做起！行动，从身边的一点一滴的小事做起！
我不能阻止人们滥砍伐树木，但我能做到节约每一张纸，不用一次性筷子；我不能阻止人们捕稀有动物，采稀有植物，但我能做到不捕稀有动物，不吃稀有植物；我不能阻止人们不用白色垃圾来污染环境，但我能做到不用塑料袋，用环保袋；我不能阻止人们乱扔电磁污染土地，污染水源，但我能做到把家中的电磁放到指定的垃圾桶里；我不能阻止人们浪费水源，但我能做到每次上完厕所都拧紧水龙头……
我不能阻止破坏环境的事情太多，但我能做到保护环境的事也不少。我可以从小事做起，从日常生活做起，从自己力所能及的事做起。我想，如果人人都这样做，那么我们的生活环境就会减少一些污染。
让我们行动起来，保护环境，做好环保。不要让地球的环境再次受到破坏了！

小草，在生活中随处可见，无论是贫瘠的荒地，还是狭小的石缝中，都能看见它的身影，它是希望的色彩，是一切生命的开始。春天，它从香甜的梦中醒来，从春风的微抚中醒来，用它那绿绿的小脑袋打探着这未知的世界。清晨的露珠滋润着它，午后的阳光照耀着它……
这是多么美好的意境啊!但由于人类科技的不断发展，导致人们越来越依赖高科技，因此勿略了绿色。
马路上，车来车往，车的尾气扑鼻而来，路边绿化带上的小草，拉耷着脑袋，汔车呼啸着从它身旁开过，并伴随着一阵乌黑、刺鼻的尾气，小草都被吹动得左右摇晃。
来到垃圾桶旁，嗅味袭人，大家都捂着鼻子走过，顺手将自己身上的垃圾、废品，像投篮一样的丢进去。垃圾堆上，是苍蝇和老鼠的天地，而在一旁的小草，早已被这污水泥泞的环境弄得枯黄、腐烂了。
再来中央湿地公园看一看，放眼望去，这里的小草自欺欺人生机勃勃，十分欢快，然而在仔细一看，其实也不全是太欢快，只见几个小孩子在没有人看管的情况下，在小草上谈话，兴高采烈的踢着足球，打乱这片小草们的平静生活，它们都被踢得连根拨起。你听，这“刷刷刷刷”的声音好像是它在哭泣。

环保作文400字：保护地球
我热爱地球，热爱我们赖以生存的家园。爱她的青山绿水，爱她的碧草蓝天……但是，在今天由于人们无穷无尽地开采资源，大自然遭到了严重的破坏。为了拯救奄奄一息的地球，世界各地都纷纷号召人们保护环境、珍惜我们现在的美好生活。
你们知道吗?蓝天指数增加一个百分点，政府投入是30亿元，而每增长一个百分点就需要100亿元。也就是每3。65个蓝天就要用100亿元去换。这不由得让我大吃一惊，原来蓝天竟这样昂贵!其实细细想来，我们生活中的一些不经意细节也可以帮助我们的蓝天。蓝天是大家共同享有的，就需要大家一起去创造。我找到了许多我已经做着的和还没发觉的一些可以帮助我们的蓝天的事。例如：早上妈妈送我去上学的时，车里有四个座位，我和妈妈各占一个。这时我们对于车的使用率只有50%，可是汽车还是排出100%的尾气，污染了大气。于是我又找了一个也是每天早上坐私家车上学
