环境污染话题英语作文(精选20篇)

在森林的小河旁边，有一个工厂，工厂每天都在排放废气和污水，还有人往小河里丢垃圾，小河越来越脏。过了几天，小动物们再也忍不住了，准备搬家了，小燕子对小鱼说：“这里太脏了，我们快走吧。”“我们的家为什么这么脏?”小鱼连忙问。小燕子说：“因为这里有工厂，工厂每天工作，排放污水和废气。”它们正说着，又看见工厂正往外排放废气和污水，排放量越来越大，小河里的水全变成了污水，废气把太阳都遮住了。小燕子和小鱼快速地走了，所有的动物都走了。几天过去了，动物们找到了新家。小河那里，树倒了，花谢了，草枯了。这就是破坏环境的下场，工厂里的人只顾经济利益，而破坏了环境。所以我们要爱护环境，保护大自然，给动物一个家，给我们一个健康的生活环境。保护环境就是保护我们人类自己。

We couldnt believe that it was a village. The buildings for the farmers were very beautiful, the streets were very clean and there were many flowers in front of the houses. In the middle of the village there was a school with a wonderful building and a large playground. All the children in the village study there.

The farmers got richer by planting vegetables and raising silkworms. In their houses there were colour TV sets, fridges,washing machines, new furniture and even motorbikes. All these showed the farmers life was getting better and better.

The great changes had attracted foreigners. Today some of them would come to visit it. We were happy for the farmers. We hope the farmers will be richer and happier.

范文二：文明旅游

有些旅游景点的文物景观遭到了严重的破坏，致使最近文明旅游的倡议越来越受重视，因此就“游客可付费在仿造长城上涂写留言”发表看法。

内容包括：(1)谈谈对某些人喜欢在旅游景点随便涂鸦留言的看法;

(2)对专门修一段仿造城墙让游客付高价留言的做法你是赞成还是反对，并简要陈述你的理由。

It is reported that tourists to China’s Great Wall can now leave their mark on a fake(伪造的) wall recently built near the real wall in Badaling if they pay 999 yuan.

In China, many visitors have the hobby of carving graffiti on places of interest, especially on some famous cultural relics. Last year I went to the Great Wall and found many people had left names and ugly words on the Wall, which destroys many historic bricks. In my opinion, such people should feel ashamed of leaving their marks on the great relics which were created by our ancestors.

So personally, I quite agree with this brilliant project though it has caused criticism from some people. The Great Wall would be ruined one day if we didn’t take any steps to protect it. The fake wall is a really good idea because it will protect our relics as well as making profits from the project

Low-carbon life is good for everyone.

To help with the environment, I always walk or ride a bike to school

instead of taking a car. Besides, I will try to use things that can be recycled

and I never forget to turn off the lights when I leave the classroom. I think

it’s my duty to live a low-carbon life. And even the simplest activities can

make a real difference to the environment. So I suggest we should reuse books as

long as possible. And we’d better not spend much money on expensive clothes.

If everyone does something for the environment, I believe the earth will be

a better place.

【经典例句】

① As high school students, it’s our duty to ...

作为高中生，……是我们的责任。

② Let’s start right now and spare no effort to do a little every day,every

hour and every minute.

让我们从现在开始，每一天，每一小时，每一分钟都不遗余力地做一点。

③ Love can make miracles.

Depending on personal experience, personality type and emotional concern, we find that some people hold the idea of living in the country, while others prefer living in the city. In my opinion, I prefer the city life, though it has advantages and disadvantages.

First of all, city life is very colorful. City is the center of the surrounding area. So, it is also the most booming place having the best things. There are many great things and wonderful activities in the city, while there isn’t in the country. For example, there are KFC, wonderful shopping mall, delicious food from various places, dancing club, different kinds of activities and so on. We can also learn the culture from all the countries. Despite city life is so wonderful, it still has many disadvantages. Nowadays, with the improvement of people’s living standard, people have more cars and more people come to city, and then the city becomes more and more crowd. As a result, traffic jam emerges, which makes great inconvenience for people to go out. What’s worse, the air pollution becomes serious day by day, which is bad for people’s health.

To sum up, every coin has two sides. Living in the city also has good side and bad aspect. Whether like living in city or not depends on individual thinking. As myself, I like living in city though I know the disadvantage of living in city.

As we all know, the environment around us is getting worse and worse more and more seriously today. Water is polluted, we have no clean water to drink. Many trees are cutting down, some animals are getting less and less. Some factories are pouring dirty air into the sky. The population is increasing faster and faster, resources are getting less and less…etc. Not only does it affect our lives and health, it also has a great affection in the future. People’s health has been greatly affected by air, noise and water pollution. Many people died of diseases. In order to live a better life, something must be done to stop the pollution. It’s our duty to protect our environment. We shouldn’t throw away rubbish everywhere. Trees are very helpful and important for us. We should plant more and more trees in order to live better and more healthy in the future.

If everyone makes contribution to protecting the environment, the world will become much more beautiful. In a word, if everyone pays more attention to our environment, there will be less pollution and our life will be better. “There is only one earth”, I hope everyone will protect our environment well.

沙溪河三明人民的母亲河，她由东向西，横贯整个三明城区，她孕育了三明的繁荣与发展，培养了三明的淳朴民风。然而，由于人类的破坏，大地的污染，让沙溪河告别了昨日的辉煌。她失去了原来晶莹、清澈的姣好面庞，变得黯然失色。有一首这样的民谣，惟妙惟肖地写出了沙溪河的变化：60年代淘米洗菜;80年代水质变坏;90年代鱼儿难寻作为三明市民，我们应该努力清洁沙溪河，让她重唱欢歌。可是，有一些人还是对此置若罔闻，这令我们心痛。于是，我们对此进行了一项专项采访。

2017年3月6日下午放学后，蒙蒙细雨中，我和同学们去了八中附近采访。去八中的路上，我们看到了许多人为的垃圾，有矿泉水瓶，烟头和纸屑，还有小孩们流行的编绳子的玩意儿。各种各样的垃圾，就像是一张美丽洁净的脸庞上的一粒黑痣，异常刺眼。街边的绿地里也堆满了垃圾，让人恶心到不忍直视!不少人看到这种不良现象，愤然之：“哪些人这么可恶?”为小花小草打抱不平。

当您走在路上，鞋底“有幸”黏住异物之时，是否可曾想过，那东西是不是你哪天路过时，明明看见了前面的一个垃圾桶，却懒得走过去而丢下的?我们应该反省。当我们来到沙溪河边，刺进眼帘的是一幅令人作呕的画面：靠近岸边的河面上漂浮着许多生活垃圾和枯枝烂叶，还有很多污秽之物，整个水面黏糊糊的一片，泛着惨淡的白光。此时的天，依旧是阴沉沉的，下着淅淅沥沥的小雨，可我们的心情更加阴沉。

此处，我们在雨中“逮”到一位叔叔，询问他对三明环境状况的看法。叔叔说，他经常看到街边有人乱扔垃圾，甚至小区里有时还会出现高空抛物。另外，街边的各种店铺，吃完了一次性的快餐盒就往外面扔，这就是所谓的白色污染。

时间久了，苍蝇和蚊子聚集了一大堆，辛苦的就是清洁工人们了。他还说，沙溪河旁经常有人走过去时随手把垃圾一扔，那种旁若无人的样子唉，希望以后环境能改善吧!”当我们问到有什么好的建议给市政府时，他滔滔不绝地说道，市政府应该号召市民尽量减少使用一次性快餐盒，严惩那些肆意破坏环境的人，让三明变得更美丽!”听完了他的话，我们也深受触动。之后，我们又陆陆续续采访了一些人，大部分人的回答跟之前那位叔叔的大同小异。

给我印象最深的是一位比我们还小许多的男孩，他说：“现在，河里很脏，到处都是垃圾。要是我是超人的话，我一定会把垃圾消灭掉，让那些乱扔垃圾的人再也不敢乱扔垃圾!”他的话是那么有童趣，却又令人深思。多少年纪比他大得多的人，还在肆无忌惮地乱扔垃圾，他们心里只装着个人利益，根本没有考虑到地球这个大家庭的安危!

夜色渐浓，雨夜降临得不知不觉。可是，就是在回家的路上，我们还能捕捉到乱扔垃圾的影子。唉，令人叹息啊。让我们携起手来，一起努力阻止乱扔垃圾的行为。因为，保护环境，就是为梦想护航!

每当我看到蔚蓝的天空被烟尘层层遮盖的时候，我就会想起保护环多么重要;每当我遇到沙尘暴的时候，我就会为植被的破坏，水土的流失，土地的沙化而担忧;每当我看到一条清澈的小溪被附近工厂所污染的时候，我就会为那些小溪中的小生命捏一把汗;每当我看到大街上不满了废纸和白色垃圾时，我就会大声疾呼：“给我一个清新的生活环境吧!”

科学的发展为人类创造了大量财富，同时也给人类带来了难以避免的灾难：水土流失、土地沙化、淡水减少、动物灭绝、物种减少等环境的破坏。在这种严峻的形式下，我们能无动于衷吗?一个小学生，能为环保做些什么呢?想来想去，还是从我做起。

在家中，我是奶奶的好帮手，给奶奶讲对垃圾也应该按照再生垃圾、不可再生垃圾、和有害垃圾进行分装处理，我们家设立了两个废旧物品箱，一个装废纸、废塑料、一个装果皮。在植树节那天，我还用自己的压岁钱买两株果树和爸爸妈妈一起栽种在森林公园，心中的高兴可想而知。在学校，作为小组长的我，就更加努力了。我和同学们坚持举办月刊环保手抄报，通过搜集大量的环保知识资料、漫画进行宣传，使每一个同学养成了良好的环保习惯。由于许多人对废旧电池的污染认识不足，随意丢弃废电池的现象十分严重，我向校长写了一封“废旧电池该往哪儿仍”的倡议书，在学校设立了废旧电池回收箱。在街上，看见一位阿姨正将吃的口香糖随地突出，我便会毫不忧豫的跑过去，告诉她，阿姨请别把

它吐在地上，而应该用纸包起来，放进垃圾箱中。试想，如果每块吃过的口香糖都被吐在地上，后果将会怎样?

我想：如果我们瓜洲县的小学生都这样做，这里的天空会变得更蓝更美，空气会变得更加洁净清新，自来水喝起来更香更甜，城市也会变得更加美丽!新世纪得笑容会更加灿烂!让我们争当环保小卫士吧!让我们大声呼喊：“保护环境，从我做起!”

每当我看见垃圾都忍不住要去清理，一点也不留，保持城市环境清洁，全靠你我他，我们怎么能让绿色的城市污染斑斑呢？

有一天，我在小区墙上看见很多小广告，就拿回家清理小广告，准备刮了小广告。我先拿来刮棒，使劲的刮，可是，我怎么也没有想到，广告刮也刮不下来。我想：难道是贴小广告的人用了什么材料，贴上去吧？我想着想着挑来一桶水，往上一泼，真的有一些掉下来了，接着，我使劲的刮，这次终于刮下来了，但是我发现地上有一些白色的小东西，回家查了下，原来这种东西会让人得牛皮癣，于是，我拿扫把把这些白色的小东西给清理了，感觉轻松了很多，旁边的老奶奶夸我是个好孩子。

经过这件事之后，我明白，如果人们都举手之劳的小事做好，世界将会更加美好。

I am a student. And I know every student need to go to school for almost 20 years, if a student go to university or college after high school, he or she will stay in school for 5 more years. So precious is time that we cannot afford to waste it. But there is a question. Whats the point of doing all this? Whats the purpose of study?

In my point of view, nothing is more importance than to receive education. The magic of education can make person intelligence, smart, and reasonable. Physics and chemistry can help you to understand the world. Math can help you to be smart and train your brain. Art, IT, and planning can help you to learn some important skill in tomorrows world. Language can help you to community with others.

So the reason why we are learn in school for such a long time is because you will understand that no subject you are taking is a waste of your time.

Math, physics, chemistry, biology, and earth science are researched by all human in the past. On the other word, it is human culture we are learning. But the most important thing is these results were discovered by the people in the past. Right now, we just have to understand it. How simple is that?

In all, learning things from school is not only for you can survive in the society in the future, but also a study of a human race.

今天，我按老师的要求去调查周围环境保护的情况。

Today, I according to the requirements of teachers to investigate the protection of the environment.

我先来到公园，就看见那儿到处都是垃圾。我眼前有一个阿姨，她坐在石凳上，吃着瓜子，还把瓜子壳扔得满地都是。我看见了很生气，就去阻劝阿姨。可她却一副事不关己，高高在上的样子。我看见有清洁工在打扫卫生，可是周围人扔垃圾的速度远比他们打扫的要快得多。

I first came to the park, I saw there was rubbish everywhere. I have an aunt, she sat on the bench, eating melon seeds, the seeds were strewn across the floor. I saw aunt is very angry, to dissuade. She has a pair of NIMBY, superior. I saw street cleaners cleaning the health, but the surrounding people throw garbage much faster than they clean the much faster.

我又来到了公园东侧的小河边，看见水面上漂浮着塑料袋、饼干包装袋……甚至还飘着几条小鱼的尸体，散发着一股股令人作呕的气味。

I went to the park on the eastern side of the river, saw floating on the water with plastic bags, packaging bags of biscuits...... Even with a few small fishs body, exudes the smell shares turn ones stomach.

我来到了菜市场，看见地上尽是烂菜叶、烂水果，还有还有家禽的羽毛及内脏，这么脏的地面让我的脚都不敢踩下去了。哎呀!糟了!我踩在香蕉皮上摔跤了，裤子都被弄湿了!我赶紧爬起来，慌忙逃离。

I went to the vegetable market, saw the ground was full of rotten vegetables, rotten fruit, as well as poultry feathers and visceral, the dirty ground make my feet have not stepped on. Oh! Bad! I stepped on the wrestling on a banana skin, pants are wet! I quickly got up, hurried away.

周围的环境简直糟透了，若再不注意保护，我们人类定将无法生存。让我们一起行动起来吧，保护环境，从“我”做起。

The surrounding environment is bad, if we do not pay attention to the protection of the human, we will not survive. Let us act together now, Protect environment, from "I" to start.

在十年前的中国，大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样，看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产，燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝，随着中国经济的迅速发展，人们生活水平的不断提高，人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题，其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬，专家们各有其立场，但对于普通百姓来说，全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖，海平面上升，冰川融化，动植物灭亡的问题，人们大多数是在电视新闻或报刊杂志上看到，恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题，人们开始关注更多的便是最近发生在北京，广州，武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康，更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象，国外专家学者很多年前便开始研究。

那么何为灰霾？灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物（PM2.5）和臭氧()、二氧化氮（）、二氧化硫（）、挥发性有机物（）等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关，还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种，直径小于2.5微米的颗粒物（PM2.5）和直径小于10微米的颗粒物（PM10）。虽然两种形式的颗粒物都对人类健康有极大的危害，PM2.5被普遍认为是更危险的，因为它的体积小，大约只有人类头发宽度的1/30。人们在呼吸时，PM2.5可以进入人类肺组织深处，甚至进入血液，造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此，PM2.5可以传播的更远，停留在空气的时间越长，影响更大的人口。PM2.5和PM10的主要来源包括机动车，电厂和其他工业源，以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合，可以在城市或农村地区天空一片阴霾，而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因，像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围，当地空气干燥，白天阳光充足。到了晚上，地表面冷却很快。地面附近的空气变冷，而上层空气都比较热，形成逆温。北京市位于华北平原的西北边缘，背靠太行山余脉和燕山山脉，面对辽阔的华北平原，东南距渤海约150公里, 地处暖温带半湿润地区，气候属于暖温带半湿润大陆性季风气候,四季分明，春季多风和沙尘，夏季炎热多雨，秋季晴朗干燥，冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远，周围地形如盆地，集热容易散热难，河湖多、晚上水汽多，城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市，而且城市海拔较低，周围至少有一面是高地，都分布在低于南北纬50度的地方。这些地区夏季阳光明媚，天气温暖干燥。在城市的盆地地区，逆温现象十分普遍。夏季的阳光使地面温度升高，城市街道和建筑物迅速升温，与炎热的物体表面接触的空气温度升高。通过对流空气向上运动，但它却不能穿透逆温层，因为上面的空气温度更暖且密度更小。空气聚集，但连续的对流形成了垂直的循环，使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下，通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集，大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响，学者称它为街谷模型。随着城市化的加速，城市及城市周边的自然生态系统逐渐被人工生态系统取代，取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续，高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时，风速迅速降低并产生特殊的湍流，使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用，因此，对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市，尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物（PM）浓度和40%的二氧化氮（NO2）浓度。因此，通过对植被的合理利用能过创造一个有效的城市污染过滤膜，对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题，相反它是一个长久的问题，从它如何形成，加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象，它只是地球环境污染的一个缩影。我们更应该探究它的根源问题，什么才是它形成的根源，什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题，但我们可以通过减少排放源，通过增加植被，加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼，越来越发达便利的交通，相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了，人们是否会怀念那晴朗的蓝天，向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

我家可是个环保“节约小组”，奶奶每天都会提醒我：“出门上学别忘记关灯啊”。这句话已经是奶奶的口头禅了，也是我每天必须听到的话，然而这句话已经深深地记在我的心中。每天去上学的路上，都会看见一些不文明的现象，有的人踩踏草地，有人随地吐痰，甚至有的人向河里倒垃圾，等等……

我想对他们说，地球是我们的母亲，我们是地球的孩子，不要随意给地球妈妈增添负担，让她难受。那些不文明的现象，其实我们是可以克服的。虽然地球妈妈还可以生存很多年，但假如有一天，地球妈妈不在了，我们还在吗?我们人类也只是生存在地球上的一种生物而已，和许多小动物小草一样。

那些踩踏草地的人们，你们不知道小草也是有生命的吗，它们为我们贡献绿色，为环境增添美丽。那些随地吐痰的人们，你们知道你的口水里有多少细菌吗，随便一吐，会让多少人有被感染的危险。那些向河水倒垃圾的人们，你们不知道你的家门口都有蓝色的垃圾桶吗，只要倒入垃圾桶，让清洁工人集中整治，会省去很多污染的。

随着人们生活水平越来越高，人类产生的垃圾也就越来越多了，还有各种各样的工业污水污染，我听长辈们说，我家附近的河，十多年前，每天都是黄色的，工厂直接排污进去，都开玩笑的叫它，黄河。现在这几年，政府注重了环保，河水经过打干排污，工厂也不在直接排污水，水质得到明显提升，夏天，现在好多人都在那游泳了。这让我感到很开心。从这件事上，我们可以看出，只要人们注意环保，都是可以改变的，虽然我们只是小学生，没有能力改变大环境，但是我们只要从身边小事做起，一样可以为创造优美环境出一份力的。

我们小学生对那些不文明现象应该提出劝告，让他们知道，破坏环境就是破坏自己的家园，让他们知道那些行为是可耻的，让人们知道，保护环境人人有责。

我相信，人类一定会努力向污染宣战，从身边小事做起，我们只要用心，一定可以减少污染打败污染的。

同学们，还记得电视台的一则公益广告吗?一只无家可归的小鸟在可怜地唱着：“我想有个家，我想有个家，我想有个家……家!在哪儿呢??”相信这个情景给大家留下了很深的印象!

地球是人类的共同家园，然而随着科学技术的发展和经济规模的扩大，全球环境状况在过去30年里持续恶化。

曾有资料表明：1860年有气象仪器观测记录以来，全球年平均温度升高了0.6摄氏度，最暖的13个年份出现在1983年以后。20世纪90年代，全球每年受灾害影响的人数平均为1.47亿，而到了20世纪90年代，这一数字上升到了2.11亿。近几年来，我国也发生了不少自然灾害。目前，世界上约有40%的人口严重缺水，如果这一趋势得不到遏制，在30年内，全球55%以上的人口将面临水荒。

自然环境的恶化也严重威胁着地球上的野生物种，加上人类的大量捕杀，许多种动物正在逐日减少。我在报纸上看到：美州猎豹早已长离世间、猛犸象早已丧命冰河、剑齿虎早就灭绝、欧洲大雷鸟接近灭绝、非洲象被逼在了绝种的边缘……我从网上获知：臭氧层被称为大地的保护伞，因为它可以挡住大部分紫外线，如果没有臭氧层的话，人类的生存将会受到威胁。可是，因为人们大量使用化学药品，南极上空已露出了大洞，臭氧层已经遭到了人类的破坏。

我可以通过以下几种方法来宣传保护环境：

1.成立组织，诚招社会各界热爱、支持环保事业的人士加入，对社会和生活环境会产生积极的影响。

2.积极主动与社会各界各阶层人士开展交流合作，用演讲传单等形式在本地区内的中小学、各大企事业单位等区域单位进行环保宣传。

3.广泛开展义务劳动和各种形式的环境保护行动。

4.开展“植树月”活动，每年争取用一个月左右的时间来绿化自己的家园。

5.大力提倡公共交通优先和绿色出行理念，每个公民尽量选择步行，减少废气排放。

6.养成良好生活习惯，把“环保”的理念树立在心中，用身体力行影响你的家人、朋友、同学及身边的每一个人。

我想，大自然既然已经向人类发出危险的警告，如果人类再不珍惜环境的话，一定会遭到大自然报复的。为了创造美好的环境，我们要珍惜大自然赐给我们的宝贵财富，从小事做起，从自己做起，保护有限的自然资源，保护人类赖以生存的环境。我希望每个人们都拿出实际行动来弥补人类的过失。

With the continuous development of science and technology, the increasing number of cars, emissions of emissions has caused serious pollution, perhaps, a few years later generations, hundreds of years after everyone, perhaps because of air pollution and death. Now, twenty percent of the people on earth every year are killed by drinking contaminated water, and if this continues, will the earth become bare after tens of thousands of years, like the moon?

According to the statistics of scientists, every year, more than 20 percent of the trees are withered by exhaust pollution every year. More than eighty percent of our useful bacteria die, and everyone may feel very exaggerated, but it is true. Followed by contaminated waste water, waste gas and so on. Is human error?

How much I hope that we can cherish every thing around us, every animal, every beneficial bacteria, because it is possible, in tens of thousands of years later today, they are gone.

Animals have warned against humans;

Bacteria have warned against humans;

Every innocent life warned us.

"Human, do not harm yourself, do not kill us again!"

随着科技的不断发展，汽车的不断增多，排放的废气已经造成了严重的污染，或许，几年后的子孙后代、几百年后的大家，或许会因为大气污染而死亡。现在，地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡，如果这样延续下去，地球在几万年后岂不是变得光秃秃、像月球一样了?

据科学家的统计，每一年，每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡，大家或许会觉得很夸张，但这是事实。其次还有受到污染的废水、废气等。人类有错吗?

我多么希望大家能珍惜我们身边的每一个事物，每一只动物，每一只有益的细菌，因为，很有可能，在几万年后的今天，他们都没有了。

动物对人类发起了警告;

细菌对人类发起了警告;

每一条无辜的生命对我们发起了警告。

“人类，不要再害你自己，不要再害死我们了吧!”

[保护环境的英语作文2篇

我知道家乡受到了很大的污染。造成家乡污染的东西有这么多，比如：汽车的尾气、工厂里的废水、废气、草坪上的垃圾等等。

污染物对环境和生物有很大的危害，它会使空气变得浑浊，对人类的肺部也有害。生活垃圾处理不好还会产生细菌，还会影响到人类的健康。污水会影响到人类喝的水，这样的话，这些水就会直接进入到人类的身体里。

所以，我建议大家做到以下几点，一.不用一次性木筷。二.不污染水源。三.不乱扔垃圾。四.不随地吐痰。五.多植树造林。六.不践踏草坪。七.废旧电池和垃圾要处理好。八.不要用动植物的东西。

我们要保护好周围的环境，不要再让家乡受到污染。
