Let’s look at the second photo. Trees are less, the water isn’t clean, and the sky is not blue. More factories were established. The village is not beautiful anymore.

It’s easy to see the environment is becoming worse. As a middle school student, we should do our best to protest our living place, but what should we do nowWe’d better use cloth bags instead of plastic bags when going shopping. We should ride bicycle instead using cat to school.

If everyone does something to the protection of our earth I believe the pollution will be reduced a lot.

人类只有一个地球，他是生命的摇篮，是我们共有的家园。行动起来、保护环境、保护大自然！

保护大自然，我们从身边的小事做起，我的家乡白云区麦架镇高寨河。我们村子前面有一条小河，河水清澈。不知什么时候，村民们总是把垃圾倒在河岸边，时间长了，垃圾腐烂了，污染了河水，河水变得浑浊，臭气暒天，污染非常严重。夏天让我们都无法游泳了。于是我找表哥孙祥云、表姐孙思悦商量，怎么阻止这害人的垃圾？我们想了一个办法：先发动全村的小朋友，把河边的垃圾扫成团，焚烧后，清理干净。然后做了三个牌子插在人们爱倒垃圾处，第一个牌子写上禁止倒垃圾，第二个牌子写上保护环境人人有责，第三个牌子宣传保护环境的重要性。

从那天起，我们姐弟仨，大清晨的就在河边等着给倒垃圾的人讲解污染的严重性与危害性。从此以后，再没人来这儿倒垃圾了，河水慢慢变清了，不臭了。

夏天，河里游泳的小朋友很多，我们姐弟仨不例外，在河里嬉水，捉鱼开心极了！

保护环境，人人有责。人们的环境意识不是很强，大量的化工企业引进的废气偷偷排放，垃圾的乱仍乱丢，水资源的浪费等等，直接破坏着人类的生活环境，很难想象，这样下去，我们的地球会变成什么样？

地球是我们人类的母亲，是我们赖以生存的家园。随着生活水平的提高，人类在享受的同时，却在不知不觉地破坏她，我们的生存环境在不断恶化。

我们的地球是怎么呢？到底是什么原因造成了如此巨大的环境灾难？经过科学家们的研究，这都是人类对大自然的污染和破坏而造成的严重后果，人类对地球的贪婪与索取是环境恶化的罪魁祸首。

人们的环境意识不是很强，大量的化工企业引进的废气偷偷排放，垃圾的乱仍乱丢，水资源的浪费等等，直接破坏着人类的生活环境，很难想象，这样下去，我们的地球会变成什么样？

我们经常在商场购物时，人们手中拎着大包小包的塑料袋。可你们却不知道，塑料袋焚烧会造成毒气，填埋后并不容易分解，还会导致土壤被破坏，中国人口这么多，可想而知会有多少塑料袋难以处理。在饭店吃饭时，人们经常使用一次性木筷，其实那样会消耗大量的树木，据说，中国人在一年的时间里要“吃掉”2000万棵大树，这样的情况难道不让人触目惊心吗？

那我们为什么就不去做一些既能保护又能节源的事情呢？我们可以把工厂里排放出来的废气收集起来，进行一定的加工处理后，把它变成有用的煤气、液化气；把废纸加工后，变成一张张有用的白纸；把洗脸过的水用来冲厕所……这样，既节约了能源，又污染不到环境。

一个人的环保行动就像一盏灯，当它亮起来的时候，周围的黑暗就会少一些。

保护环境，人人有责，到那时，我们的祖国大地遍地是青山绿水，红花绿草，天空则是蓝天白云，鸟雀萦绕。让我们为此而点亮那盏属于自己的光明之灯！

在我们身边，有这样一些景象：道路上，垃圾四处丢；河流中，废水天天见；空气中，各种“黑龙”肆意排放，臭气熏天…给我们的生活了带来重大的伤害！树木砍光了，只要暴雨来临，水和泥沙形成巨大的泥石流，后果不堪设想；“黑龙”污染蓝天，使人无法正常呼吸；河中废水有人喝了，就引发了水中毒……

难道这些不引人深思吗？在环境污染日益严重的今天，我们又能做些什么呢？在人们随手丢垃圾时，在人们向河里倾倒废水时，有多少人能想到他们毁灭了自己没有？所以，保护环境势在必行！我们必须控制好自己，不乱扔垃圾，就能少一份污染；多种一棵树，多一份绿色；多安装一台废水过滤机，多一份洁净健康；少排放废气，还我们一个湛蓝的天空……让我们的家园干干净净！由此，我郑重、严肃地向还未意识保护环境的人们提建议：

1、以节水为荣，随时关上水龙头，防止滴漏。以节约粮食为荣，尽量地把残留的食物吃完。

2、尽量少用一次性物品，多使用耐用品，自备购物袋或提篮，减少白色污染。

3、不乱丢垃圾和废物品，将垃圾分类投放，变费为宝，使资源循环再生，造福人类。

4、不猎杀珍惜动物和受以保护的动物，关爱与保护野生动植物；植树造林，爱护我们身边的每一朵花、每一片草和树木。

5、不随地吐痰，不随地大小便，不在公共场所吸烟和不制造噪音。

我倡导大家赶快行动起来提高保护环境的意识。为保护环境、造福后代贡献自己的力量。因为，保护环境，刻不容缓！

Protect Environment

Today there is more and more pollution and the environment is becoming worse and worse. So we have to know how to protect the environment. Here are some ways.

First, we can stop driving our personal cars. We can go to school or work on foot or by bus. Not only can it protect environment, but also it is good for our health.

Second, we are not supposed to drop litter anywhere, we should put them into the trash bin. And it’s best to pick up the litter on the ground when we see them.

Third, we should save the paper, the water, the food and so on.

Fourth, we should protect the trees and we should plant more trees.

I think if everyone does something to protect the environment, our world will be much better.

[保护环境的英语作文4篇

保护我们身边的环境，是我们的责任。说保护环境，人人有责这样的话的人大有人在，可真正做到的有多少，微乎其微。

我们知道，保护环境先要从身边的点滴小事做起。放学回家后，看到家里整整齐齐，那一定是妈妈的功劳。第二天上学路上，道路一尘不染，那是清洁工的任务，到教室，看到教室焕然一新，那是同学们共同努力的成果。

这些都是不必要的，如果我们物品摆放的很整齐，垃圾丢到垃圾箱里，上了一天班的妈妈就不会这么劳累。如果我们在路上把零食袋放到指定的位置，就会为清洁工减轻一些负担。打扫教室就更不用说了，同学们都有保护环境的意识，捡起桌下的一张纸，就意味着干值日的同学可以早一点回家。

保护环境不仅是捡起身边的垃圾，让周围整洁，还要让耳朵清净。

公园里，每天的游客很多。早上，有些老人喜欢唱歌，在广场上跳舞，这些都少不了声音。再加上孩童玩耍、大人们聊天、商贩们吆喝的声音，似乎让原本安静的公园变得嘈杂。物理课也学到了关于声音的课时，我们也了解到了听力对我们的重要性，所以保护环境少不了让耳朵清净。

保护环境最根本的的还是保护空气。

工厂排放污水、释放有毒物质都会影响环境，解决空气污染是当前的任务。我们山东的空气质量一直是良，怎样才能改善呢？据统计，济南某日空气质量为严重污染，PM2.5、PM10等有害气体增加，使市民的身体健康遭到严重危害。

光说不练假把式，让美好的光环从我们身边扩散。

Economic development and environmental protection are a pressing issue primarily for developing countries where, in trying to catch up with developed countries, they have to consume natural resources on an unprecedented scale. This has seriously polluted our environment and, with the global environmental campaign gaining momentum, many people in China call for the precedence of environmental protection over economic development.

Any attempt to pose economic development and environmental protection as diametrically contradictory is simple-minded. Since no country is willing to stop its economic development, the best way is to strike a balance between the two and to heighten the environmental awareness of those solely concerned with economic development.

European countries both economically developed and environmentally friendly can serve as perfect examples for China. Their success story in both undertakings illustrates that environmental protection does not mean a complete standstill of economic activities or exploitation of natural resources, but rather an active development and application of effective technologies to minimize environmental consequences. In Germany, environmental protection has become part of economic development as it boasts the world s most successful environmental industry. With a developed economy, we are well equipped to develop sophisticated technologies that can effectively safeguard our environment.

When the founder of Facebook, Mark Zuckerbergs daughter was born, he

announced a general decision and surprised the world. Mark told media that he

would donate 99 percent of his fortune to the charity organizations. Some people

wonder why he did not save the heritage for his offspring. In fact, in western

countries, for some rich people, they dont trend to leave much fortune for

their kids, instead, they use the money to educate their children and cultivate

them to be the wise persons. The rich people leave the invisible fortune, which

is their fame. Their children can have more chances to do their business or

receive better education with their family names. The wise rich men know the

best way to educate their offspring. They teach skills and the way of thinking,

which values everything.

随着人类科技的发展，那些清澈透亮的河水、湖水似乎离我们远去了，取而代之的则是漂满垃圾的脏水。阳光下，再也闻不到来自水的清香了，只能嗅到一股股恶臭。

城市里的水道上总会有许多垃圾：水面，塑料袋与饮料瓶你拥我挤地和荷花浮萍争地盘;水中，一根根烟蒂漂浮着嬉闹游玩;水底，鱼儿们穿梭于纸团纸屑之间，玩得不亦乐乎。水，已全然失去了以往的姣好容颜，当垂柳依依多情地想照“镜子”时，却发现“镜子”已肮脏无比，忙缩回了头;当蜻蜓款款飞来想点水起舞时，却发现水已恶臭不已，忙飞向花丛;当燕子南飞归来想找昔日好友时，却发现好友已狼狈不堪，忙跌跌撞撞飞走了……造成这一切的罪魁祸首，可是我们人类自己呀!

水，对地球上的生物来说，是生命的根本;水的干净与否，决定着我们的生死存亡。所以，现在的各个河段、湖泊上，总会发现一队队划着小船，辛勤打捞水上漂浮物的清洁工叔叔阿姨们。橘色的衣服是他们的标志，清亮的汗水挥洒着信念的光辉。

水资源的减少让人们有了觉悟，但只有少数人能做到保护水资源，多数人都未能清楚认识到保护水资源的重要性。不过，“五水共治”行动已经轰轰烈烈的开展，各种治水方案也已在实施中。相信在不久的将来，清澈的水源将重新呈现在我们面前。

让我们从我做起，充分发挥个人和集体的力量，保护水资源，让我们的地球和我们生命都能得到净化!

[英语作文：保护学校环境

常熟是一座文化古城，自古以来，它都是以悠久的历史和璀璨的文化闻名于世，这些年来，常熟陆续被授予“国家卫生城市”、“全国环保模范城市”等称号，近几年还被评为了“国际花园城市”，常熟也是全国县级市中第一次获此殊荣的城市。

这些年常熟为我们增添了不少的光彩，但是人们渐渐地，开始并不怎么注意环境卫生了，随手一扔垃圾，随地小便，随地吐痰,扔废旧电池，把一些地方弄得肮脏不堪，更可恨的是，大多数的农民为了贪图省力，在高速公路旁的田里焚烧菜杆，烟雾弥漫在天空中，会影响行使在高速公路上的车辆视线，引发重大交通事故，还有更严重的，我们的自然书上说过：如果，人们再在露天的地方燃烧物品，下个世纪，世界将会升温两度。

这还不算什么，现在环境污染了，动物们也都会死的死，逃的逃，就像我们常熟的阳澄湖大闸蟹，田野里的青蛙，树上的小鸟……同学们，动物也是有血肉的，就这样对待它们，我们的心是否也太狠毒了，动物也是人类的朋友啊！

同学们，为了我们美好的明天，美丽的家园，让你我共同行动起来吧，倾心同护蓝天碧水，携手共建生态常熟！

记得几年前，爸爸妈妈带我去看望外婆，外婆家门前有条小河，河水清凌凌的，闪着金光，缓缓地向前流着。河边，一群阿姨正欢笑着在洗衣服，一群孩子在河中游泳、嬉戏。我与妈妈挽起裤脚在河边捡鹅卵石，爸爸在旁边悠闲地垂钓。这安乐祥与的景象，现在我还记忆犹新。

然而，几年后的一天，当我再次看到那条河时，不禁吓了一跳。河水已经不清澈见底了，水是浑浊的，还夹杂着一些脏东西，光秃秃的河床上，水已快枯竭了，还散发着臭气。这些臭水是从哪中流出来的呢？我放眼望去，只见几家工厂正向天空喷射着烟雾，烟雾污染了白云，然后变成酸雨飘落下来，毒害大地；同时，工厂还不断地向河流排泄废水，将清清的河流变成了浑浊的毒水。煤是大自然几亿年蕴藏的太阳能，而在短短的几百年内得大量的开发与利用，大量的煤炭燃烧生成二氧化碳，造成了地球的温室效应。同时煤中数少量硫的燃烧生成二氧化硫气体，随雨水降到地面上，形成酸雨。酸雨毁坏了大量森林，成为生态系统的“空中杀手。”

排水场的水还不断地向河中排放污水，就连河边的植物也死去了。这不就是垃圾场吗？原来干净的河水不再清洁，河水也不再流淌、空气不再清新。人们到底对这条相伴多年的老河抱着什么样的态度呢？是继续污染环境还是保护河流呢？是做破坏者还是做环保者呢？

由于水源的污染与地下水的超量开采，人类的淡水资源已经开始告急。由于森林的砍伐与过度开垦，放牧、水土流失与土地沙漠化问题日趋严重。由于地球的破坏，截至2000年已有2、3万种植物与1000多种脊椎动物绝灭，现在每小时就有1种生物从地球上消失。土地污染，人类乱砍树木，岩石下滑，洪水冲毁了房屋，淹没了庄稼；人们往河中乱丢垃圾，造成了水污染，到处可见随手扔掉的塑料口袋，形成白色污染。人们乱杀动物，造成动物灭绝；人们乱摘花木，使我们失去了美丽。人类只有一个地球，我们生活在地球上，就要保护地球，保护我们的家园。

为了家园，为了我们自己、为了造福子孙后代、让我们携起手来，保护自然环境，用我们的努力创造新天地。我们相信，明天一定会更加美好！

尊敬的市长伯伯： 您好，非常激动能够给您写信。

您最近身体是否很健康?工作是否顺利?最近雾霾天气相当严重，您别忘了出门前要及时戴上口罩，以免影响您的身体健康。

为什么最近雾霾天气会如此频繁呢?原因有以下三点：

1.在水平方向静风现象增多。城市里大楼越建越高，阻挡和摩擦作用使风流经城区时明显减弱。静风现象增多，不利于大气中悬浮微粒的扩散稀释，容易在城区和近郊区周边积累。

2.垂直方向上出现逆温。逆温层好比一个锅盖覆盖在城市上空，这种高空的气温比低空气温更高的逆温现象，使得大气层低空的空气垂直运动受到限制，空气中悬浮微粒难以向高空飘散而被阻滞在低空和近地面。

3.空气中悬浮颗粒物的增加。随着城市人口的增长和工业发展、机动车辆猛增，污染物排放和悬浮物大量增加，直接导致了能见度降低。

我想，这三点因素一定就是雾霾产生的原因了。我们小学生不仅要知道雾霾产生的原因，还要注意自我防护，像：雾霾天气少开窗、外出戴口罩、多喝桐桔梗茶、适量补充维生素D、

饮食清淡多喝水等。

让我非常惊讶的是，石家庄在中国空气质量指数排行榜仅仅排名第97位。这令我十分难过，没想到从小生活的城市空气质量那么差!不过更惊讶的是首都北京竟然是排名“倒数第三”，太可怕了。

我认为，地球三大生命要素是：空气、水、土壤。只要这三种少了一种，人类就会灭绝。所以保护环境是非常重要的。环境是人们所在的周围地方与有关事物，一般分为自然环境与人文环境。人文环境保护好了，自然环境就会好。

我们目前是小学生，虽然我们还没有办法保护祖国的环境，但是我们有能力保护好校园的环境、社区的环境以及街道的环境。

从小做起，从我做起。保护环境，人人有责!在这里，我提议：

1. 利用电视台向全国人民发起倡议，在自己生日当天种下一颗树。

2. 提倡汽车单双号出行，可以严重减少尾气排放、

3. 工厂搬出市区。

4. 拆掉小锅炉，采取集中供暖。

希望以上几点能够给您一些建议!

再次祝市长伯伯身体健康、万事如意!

此致

敬礼

小学生董伊飞

广大人民群众：

蓝天白云、繁星闪烁、健康宜居的优美环境，是我们的共同期盼与向往。然而，治理大气污染绝非一日之功，也绝非仅凭一己之力，必须全民行动，共同参与。尤其是近期重雾霾气象条件频发，空气质量持续较差，更需要全县人民戮力同心，众志成城，打一场污染防治的人民战争。为此，我们呼吁：

一、关注环境，更新观念

大气环境同每个人息息相关，每个人都要关注大气环境质量，学习大气治理的政策法规、健康风险防范等知识，树立良好的环境价值观，做大气污染防治的践行者、推动者。

二、节约资源，降低能耗

自觉养成绿色消费的好习惯，每天节约一度电、少用一张纸、少抽一颗烟;日常生活中尽量减少垃圾产生，对可回收垃圾分类处理、循环利用，减少垃圾转运、焚烧过程对空气的污染。

三、绿色出行，低碳生活

尽量少开车、不开车，优先步行、骑行或公共交通出行，多使用共享交通工具，家庭用车优先选择新能源汽车或节能型汽车。

四、依法生产，主动作为

各行各业生产经营者，是大气污染防治的责任主体，应主动履行社会责任，防污减排，尤其是在重污染天气预警期间，要坚决落实各项应急措施，最大限度减少排放。

五、禁烧禁燃，减少污染

抵制露天烧烤，减少油烟排放，不焚烧垃圾、秸秆、树叶、杂草，不燃放烟花爆竹;推广使用清洁能源，抵制劣质散煤，尤其是实现“气代煤”“电代煤”的区域，严禁使用散煤，县城内散煤“清零”。

六、加强宣传，勇于监督

当好大气污染治理的宣传员、监督员，对严禁散煤木柴燃烧、严禁燃放烟花爆竹、严禁柴油货车进县、严禁露天焚烧等，进行大力宣传;履行生态环境保护义务，劝阻、制止或通过12369平台和环保热线举报大气环境违法行为。

全民动员，保卫蓝天;美丽故城，你我共享。让我们携手奋战，决战决胜，改善空气质量，实现蓝天常在。

世界原本是美丽的，而被人类污染的世界是丑陋的，世界上有的河水是绿色的，里面有很多垃圾，而且非常臭呢！世界上有些地方的大路和小路上都是垃圾，一开车就踩到没吃完的食物和没喝完的饮料，把牛奶盒压出牛奶味，会招惹苍蝇，还会变得很臭、很恶心。

世界很大，也就代表垃圾也很多。扔在地上的香蕉皮会让人摔跤，草地上的大树也成为受害者，吃完就随手一扔，很容易扔到大树。大树会很容易发臭，有蚂蚁爬来爬去，严重的还会枯萎。

爱护环境有个小故事。有天早上，我在校园的操场上看见一个男孩子，吃完了零食就随手把包装袋扔在了地上。我赶紧跑上去，说：“你这样做不对。会破坏校园环境。”我还叫他把垃圾扔在垃圾箱里。小男孩看我一眼，就立刻跑开了。我弯下腰拾起包装袋放进了垃圾箱。老师表扬了我，我很高兴呢！

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，从自己做起！行动，从身边的一点一滴的小事做起！

保护环境，人人有责！相信这句公益用语大家都听过，可真正做到的又有几个？

植树可以为人类抵御沙化，美化环境，涵养水源。可人类却乱砍滥伐。地球森林覆盖率已经下降了20-30%，如果再不加以节制，不但一些珍惜动物会失去美丽的家园，濒临灭绝，而且泥石流、台风、沙尘暴等许多自然灾害会更加频繁的出现，最后的受害者，终究是人类。

往日清澈的河水不再清澈；绿色的青山早已裸露，臭气熏天；欢快的鱼儿也逃脱不了悲惨的命运，集体中毒，围绕着海岸，看到这些画面，我仿佛听到了它们的求救声，我心如刀绞，为人类的“杰作”而感到羞愧。

湿地，也面临被改变、丧失的危险，工厂大量地排出废气、废水、废物，使生态环境失去平衡、恶化。

为了一时的利益，而葬送了子孙后代。地球资源本可再生，可人类滥用化学品，让资源不可再生。

地球只有一个，我们也只有一个赖以生存的美丽家园。我们一定要善待地球，保护资源。爱护地球，保护环境，就是在保护我们自己，为子孙后代留下美好家园！让我携手并肩，保护环境吧！

Global warming in the Antarctic glaciers melt faster, sea level will rise rapidly, life on earth will have ones head above water. I told grandpa, this is too much carbon emissions. When the Spring Festival, we do not have as they often buy a lot of fireworks, fireworks set off once the only in the New Years eve, can rise to exult beaming atmosphere is ok, otherwise the carbon dioxide is really too much, families, cumulative emissions are impressive. I appeal through the Internet, the farmers dont in the wheat straw burning, after the autumn harvest of freshwater and sell special corporations to finish molding fuel, can not only generate economic benefits, can save the environmental protection, protect the earth.

全球气候变暖，南极的冰川消融的速度在加快，海平面将急速抬升，地球上的生物将有灭顶之灾。我告诉爷爷，这都是碳过多排放惹的祸。春节时候，我们没有像往年买上许多烟花燃放，只在除夕燃放过一次鞭炮，能起到欢腾喜气的气氛就可以了，否则产生的二氧化碳实在是太多，家家户户累积起来，排放量实在惊人。我通过互联网发出呼吁，农民秋收后不要在把麦秸集中焚烧了，可以变废为宝，卖给专门公司制作成成型的燃料，既能产生经济效益，有能节约环保，保护地球。

The national level protection animal giant panda, have you ever seen giant pandas? Come and see! The following is a lovely giant panda, see how delicious it eats! The smile is so lovely.

You said, why so little panda, it is because of the destruction of the human disorderly cut down trees, dont take care of flowers and plants, destruction of the atmosphere, to lead to a drop in the panda, so we have to take care of the panda, the giant panda is herbivorous animals know, likes eating bamboo, but not as the giant pandas in the zoo keepers to feed their fruit. Wild panda anecdotes: in recent years, scientists found hidden cameras, male wild pandas left a breath marks on a tree, will lift a leg, like a male dog, and then the urine to the heights of the tree and. The higher the urine, the higher the social status of the male giant panda. Good play! Just like a dog! This is fun. Ax mountain in north of the city, we established a lush bamboo sea and the forest, form different from downtown chengdu "microclimate", in 1987, formally completed, now has developed into a specialized in endangered wildlife research and breeding, protection of education and education tourism, a nonprofit organization.

Do you know how pandas digest bamboo? Researchers have found that the giant pandas digestive tract is short and simple, and there is no such thing as a long, plant-eating animal with a thin gut and a complex stomach or a developed cecum. In addition, the giant pandas genome sequences announced in 2009, after they found the giant panda to the lack of some help in the digestive tract herbivores digest cellulose and hemicellulose (they are the main components of the fibrous plant diet) enzymes. This is confusing for researchers, and how does the lack of these necessary conditions digest bamboo?

Researchers use of gene sequencing technology, analysis of more than 5000 ribosomal RNA sequences, eventually in the giant panda, found a variety of digestive tract bacteria and some microbes are very similar to grazing animals. These help animals digest cellulose in their bodies, and seven of them are unique to the pandas digestive tract. Bye bye!

保护地球，保护生态环境是我们每一个人的责任，这是我们都知道的一句话，可有多少人能真正做到这一句话呢？

记得我有一次去外婆家，外婆家里都干干净净的，却有一股酸酸臭臭的气味从窗户传过来，我跑过去一看，原来是一条小河，只见那条小河浑身发黑发臭，风一吹，臭味迎面扑来，使人不得不紧紧捂住口鼻，而且还有许多纸袋在河面上飘着，这条河怎么会这样呢？我带着疑问去问了外婆，外婆他说“在我小时候，这条河清澈无比，有许多小鱼小虾在河里面欢快的生活，而且没到夏天炎热的时候，我们都会成群结队的到河里游泳或抓一些小鱼小虾回去。而现在，人们不讲卫生，把垃圾扔到河里，逐渐的，河水发黑发臭，小鱼小虾全都死了。在夏天时，别说游泳了，连经过时也要捂住鼻口，迅速走过”。“那没人管吗？”我又问道。外婆回答说“我们曾经在河边立了一个牌子，上面写着：‘爱护小河，请别往小河扔垃圾，所以就不管了。”听完外婆的话我陷入了沉思，如果时间上人人到处扔垃圾的话，那地球上一定会脏乱不堪吧。所以请爱护地球，保护生态环境。

保护环境，从我做起，从点点滴滴做起，我们应该保护花草树木，珍稀水质源。如果每个人都少用一滴水，那一定能使一条条干枯的小河重获升级。为了地球的明天，人类的未来，让我们行动起来，节约能源，保卫家园，从我们身边做起。
