关于环境污染的英语作文简单【精选20篇】

As we all know, pollution is harmful to living beings. There are many

different types of pollutions in this world. For instance, water pollution, air

pollution, noise pollution and so on. Water pollution cause many kinds of

disease that have negative effects on human beings, sometimes the diseases will

take people’s life away. Dirty air will increase the rate of getting lung

cancer. While the noise pollution will cause insomnia. People’s health condition

will be damaged.

In my humble opinion, people should take measures to control the pollution.

Recently, not only the government, but also individual has taken part in the

action of protecting the environment. This is a good sign. Rivers are being

cleaned, air is purified, and the people come to realize that the importance of

protecting the environment.

However, this is not enough, the problems are still exist. Not all of them

have been solved. Some factories are still pouring dirty water into the rivers

or give off the toxic gas into the sky. We should know that protecting the

environment needs everybody’s effort.

With the improvement of our living standard， more and more people can afford a car. As a result，our roads are more often than not crammed with cars.

However，with more and more waste gas being discharged by the cars，the problem of air pollution bees even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike， we can not only exercise our body but also protect our environment.

Why not have a try， my dear friends?

与我们的生活水平的提高，越来越多的人都买得起汽车的。因此，道路往往没有堆满了汽车。然而，随着越来越多的废气排放是汽车、空气污染问题变得更加严重。所以此刻我们提倡过低碳的生活。

我的推荐是我们就应更经常骑自行车而不是开车骑一辆自行车，我们不仅仅能锻炼身体，也能保护我们的环境。为什么不试试，我亲爱的朋友?

为了我的新装置能早些给人类带来福音，从现在起，我要更加勤奋学习，学习更多的科学知识，掌握足够的本领，实现更多的梦想。以下内容是小编为您精心整理的汽车尾气污染环境作文，欢迎参考！

汽车尾气污染环境作文一

我是一名农村小学四年级的学生，经常生活在农村里的我，对省城——西安的模样一无所知。在春节里，爸爸、妈妈决定把我带到西安去游玩。正月初六那天，我们一家人兴高采烈的出门了。初春的阳光照在我们身上感觉格外舒服。到了西安城，我看见在车水马龙的城市里，一股股浅蓝色的烟气从一辆辆机动车尾部喷出，呛得我睁不开眼睛，甚至感觉有点头昏。爸爸说：“这就是我们所说的机动车尾气，它的颜色怪异，而且气味令人头昏、恶心，神不知鬼不觉地影响人的身体健康。”妈妈又接着说：“汽车作为陆地上最主要的交通工具，它已经成为现代社会文明的标志。但汽车所排放的尾气已对大自然和人类造成及其严重的危害。”听了他们的话，我心里沉甸甸的，作为一名小学生，长大后能不能变废气为宝呢？

回到家后，我开始思索着。我在家里纸上画一画，结合我们日常的生活用品，我想研制一种新汽车，安装汽车尾气能量回收利用的空调装置，不但回收利用了汽车尾气的能量，还节省了能源，同时使汽车有空调器制冷的效果，降低汽车空调的生产成本，这种汽车尾气利用装置可安装在汽车轮子不同位置。

新装置安装在汽车排气管上，利用尾气与空气间温差导致的热效应，形成电能，我们可以利用尾气来发电，通过电动机驱动汽车。多余的电能，可以接到在家里，就可以节约燃料，减少用电量，真的是一举多得呢。也可以安装尾气净化装置，把有毒的尾气转换成氧气，也可以根据个人的爱好转换成各种各样的香气。

为了我的新装置能早些给人类带来福音，从现在起，我要更加勤奋学习，学习更多的科学知识，掌握足够的本领，实现更多的梦想。

汽车尾气污染环境作文二

每年有越来越多的汽车在新车的人数以百万计的生产道路。出六个一工程美国人制造汽车，驾驶卡车，修建道路或填补气体。美国人不能没有车！

大多数美国人将很难想象没有汽车的生活。然而，一些已经认识到空气污染严重的问题，汽车造成的。污浊的空气变成有毒的和危险的健康。

一个办法让污浊的空气，就是自己做，无污染的汽车。但要建设一个清洁汽车谈何容易。在这一领域的进展非常缓慢。

另一种方法是别的东西取代汽车发动机。发明者现正蒸汽汽车以及电动汽车。许多厂商认为，这将需要几年发展为我们实践模式。

为了防止世界被污染的汽车，我们要在我们的生活有所改变。例如，美国，不得不削减对它们的总人数下降cars.They鼓励使用自行车，这被认为有助于保持空气清洁。

但是，这一变化来之不易。阿大批工人可能会发现自己没有工作，如果汽车厂cioses了。因此，空气污染问题将变得并不重要，重要的失业问题。虽然汽车已使我们更好的生活，他们也给我们带来了新的问题。

Good afternoon, everyone!

We are studying in this school, and it is our duty to keep it clean and tidy. It’s not good to spit in public places, such as in the school library, in the classroom, etc. We should neither draw pictures on the walls nor throw rubbish here and there. I think we must make it a rule to do some cleaning every day. If everyone tried his best to do something useful for our school, I’m sure it will be more and more beautiful.

That’s all. Thank you.

我们小组为了完成老师步置的任务：环境保护与垃圾污染。认真地去社会中去调查。调查完了后的我们深受感触。垃圾满天飞，到处都成了垃圾堆放处;美丽的滇池已是塑料袋游玩的地方;慈祥的母亲河盘龙江正在被垃圾恶魔折磨着。

我到我居住的小区里观察。大部份人都很讲卫生。但有一些小朋友为了图方便，把垃圾乱丢在地。我见了便去告诉他们不要乱丢垃圾。有一次，我见一些小朋友乱丢垃圾便跑过去着急地说：“别乱丢垃圾，要不然空气会不新鲜。”他们听了便认真地点了点头，然后就飞快地跑到旁边的垃圾桶前把垃圾丢了进去。然后朝我笑了笑，说了声：“谢谢!”就开始玩躲躲猫了。我看了很高兴，因为只要提醒乱丢垃圾的人，他们会很自觉地改过来，这对环境保护很有利。

但有几次事使我对这个观点产生怀疑。

有一次，我在去作文班时，看见一个阿姨把吃玩的糕点袋子随手一扔，后面刚好有一个清洁人员，他看见了默默地把袋子扫进垃圾铲。等清洁人员走了，我跑上前对那个阿姨耐心地说：“阿姨你刚刚丢垃圾是不对的，而且你后面是一个清洁人员，你应该把……”那个阿姨不但没有认错，而且还不耐烦地说：“应该什么?你乱说什么，后面的清洁人员扫垃圾是他的工作，我乱丢垃圾根本没错。

旁边的三个人还理直气壮地说：“对的，对的。”我生气地看了他们一眼，快速地上了车。

后来我看见电视上也看见好多广告也都在极力让人们保护环境，确定了答案。自信地把调查表交给了班主任。

我的家乡在洛阳市吉利区。这几年来，我的家乡环境变坏了。

我听说，十几年前河阳广场上的水很清，但是现在却变的半青半黑的。这是为什么呢？

在十几年前，河阳广场上的小河里的水清澈见底，像一面镜子。人们用河里的水浇庄稼。可是现在因为一些工厂把废水排泄到了小河里，还有一些人为了方便，把垃圾扔到了小河里。所以河水才变得又青又黑。我每次从河边过的时候，河水"哗哗"的响。好像在说："乡亲们呀！以前我帮你们浇庄稼、供你们欣赏。你们却不懂得珍惜。"

每当我从小河边走过时，都忍不住想对那些把废水排泄到小河里的人，和把垃圾扔进河里得人说："我们只有一个地球，我们要爱护这个地球，把它变成一个绿色的星球。"

人类在生产生活的过程中，每天都要产生大量的废弃物、垃圾和排泄物。这些物质若果得不到有效处理，就排放出来，就会造成环境污染。

人们产生大量的废弃物、垃圾和排泄物进入大气，就会形成大气污染，尘埃降低能见度，影响生产，还会造成人类呼吸系统疾病;进入河流湖泊，就会造成水质恶化，破坏水生生态，影响工厂、城市、居民用水;进入土壤，破坏耕地，污染物还会通过植物生长积累毒性，最终影响人类健康。

环境污染弄脏了我们的大气和水，破坏了大地，损害了我们的健康。我们应该防止和治理环境污染。

The trickle of water was crystal clear, accompanied by the sound of the "ding dong" of the spring. The undulating mountain stands erect, majestic and overwhelming; The green trees, towering above the tops of the mountains, are not afraid to be afraid; The wild flowers, which are in the top of the mountain, are full of beauty and beauty, and the fresh flowers are pleasing to the soul. But that was all have become memories, is facing a murky water, batteries, plastic bags have polluted the land, industrial waste gas, automobile exhaust pollution the air, trees and flowers are hard to meet again, only can see is just a weak looking trees flowers and plants, all everything has disappeared, the earth on a red alert. The presidents of all countries have been together for three days and three nights... "The whole people moved to the moon," they were consulted, and they issued such an order. According to the scientists observed earth damage is too severe, human will not far from the end of the world, if you dont leave the earth, mankind had to count the days such as dead. The present moon, which has been constructed by human ancestors and modern humans, has been transformed.

The lush woods, the crystal clear water, the blue sky, and the various shapes of flowers and animals. "Wow! This is like a new earth, and it brings us back to the old days." people dont sigh. Yes, the moon has now and once the earth is almost the same as the air around the moon, the moons gravity, and thick atmosphere around the moon, everything seemed to go back to the once upon a time, people are living down here... "Wow! There are so many trees here! ", "wow! There are so many rivers here!" Greed once again led the human hand into the abyss...

For a long time, the moon returned to the earth and the earth was devastated, and everything on the moon was dead. All the pollution to the moon, the atmosphere became thin almost close to zero, tragedy staged again, once upon a certain day a diameter of 40 kilometers meteorite broke into the moon, because the moons atmosphere is too thin, almost no resistance, is this meteorite is easy to break into the moon, because there is almost no resistance, meteorite impact force is very big, hit ground surface cracked a big hole, the hot, liquid mass of molten rock from cracks in shock... Facing death of that a moment, human beings finally wake up, but the wake up, now is just unable to struggle, ridiculous human this time really redeemed himself again. The world has been destroyed, mankind has perished.

The Spring Festival is our traditional festival, the common saying is that it is a new year.

One day before the new year, people would go to the shops in the sea of people to buy things. Some people buy chickens, ducks, goose, some people buy fish and meat, and others buy Biscuits, chocolate and other snacks...

One day at noon, my father took the broom and sweep around the house. Mother wiped the table and the window with a rag. And what about me? It is to put the ornaments of the new year on the wall. The whole house became clean and beautiful. We are very happy.

The new year, for our children, is the most addictive, I look forward to that day early.

Now, in our life, the most serious environmental problems is the soil has been destroyed, climate change and energy waste. According to the reference news reported that the 110 countries can reduce the degree of arable land. In Africa, Asia and Latin America, the bare land has become vulnerable due to the disappearance of forest vegetation, the excessive exploitation of arable land and over grazing of pastures. The earth mother has become sallow and emaciated, please take good care of our mother earth. Some experts predicted that in the near future sea level will rise, many islands will be submerged.

How do we stop it? In fact, the protection of the environment is not as difficult as it is, as long as we start from the minor matter, will make the earth a new, for example: more use of environmental protection bags, as far as possible to avoid using plastic bags; as far as possible to take the bus, as much as possible to reduce vehicle emissions; usually more than walking, riding a bicycle, exercise and protect the environment......

环保是我们这个时代充满争议的流行词，但同时是保护环境中极其重要的一点，我们如何做到环保，如何最环保，怎样才算环保呢，在以下内容中，我们将知道。

环保是指环境保护。环保是指人类为解决现实的或潜在问题，协调人类与环境的关系，保障经济社会的持续发展而采取的各种行动的总称。

现在，我们生活活中，最严重的环保问题就是土壤遭到破坏，气候变化和能源浪费。据参考消息报道，110个国家可耕地的肥沃程度在降低。在非洲，亚洲和拉丁美洲，由于森林植被的消失、耕地的过分开发和牧场的过度放牧，裸露的土地变得脆弱了。大地母亲已经变的面黄肌瘦，请好好保护我们的大地母亲!有专家预计，在不久的将来海平面将升高，很多岛屿都将会被淹没。

那我们该如何制止这一切的发生呢?其实，保护环境并没有想象中的那么难，只要我们从小事做起，就一定会让地球焕然一新的，比如：多使用环保袋，尽量避免用塑料袋;尽量坐公交车，尽可能的减少汽车排放的废气;平时多步行，骑自行车，锻炼身体又保护环境……除此之外，还有很多很多，只要我们从小事做起，积少成多，积沙成塔，就一定会让地球重还以前的面貌。

让我们为地球的将来而奋斗吧!

[关于保护环境的满分英语作文精选

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

With the development of our society， energy in the world bees more and more

limited， so it is quite important for us to save energy and to protect our

environment。 As a student， there are a lot of methods we can do to save energy

at home。 For example， first， we can turn off the light as well as other

appliances when we are not using them。 Second， recycle the waste water， paper

and other waste so that we can reuse them。 Whats more， it is suggested to use

public transportation more instead of private cars.

Above all， everyone can make a great contribution to our environment。 I

hope I can learn more to develop new and clear energy， like energy from the wind

and solar.

早上，我和妈妈决定去打扫家门口的街道环境污染作文100字环境污染作文100字。

首先，来到了家附近的一个垃圾箱旁，我发现邻居们都把垃圾扔到了垃圾箱外面，堆起了一座“小山”，垃圾正慢慢的腐烂发臭，引来了许多苍蝇。实在太臭了，所以，我带上口罩去清理。清理好垃圾箱，我又来到路边上，清理行人乱扔的垃圾，到处都是纸屑，我扫了半天才扫好。

今天，我打扫了家附近的路。才觉得，打扫卫生的叔叔阿姨真伟大，天天都把我们的地球妈妈打扫的干干净净。

一天，小燕子飞在小河上空，远处工厂的烟囱里冒出一股股灰烟，遮着了太阳和蓝天。

漂着垃圾的小河里，小鱼探出头来，它问道：“你知道为什么河水那么脏吗?”小雨嫌弃的看着自己身边的漂浮着的垃圾。

小燕子叹了口气说：“那是人类不爱护自己的家园造成的。”

“我真羡慕你，如果这个地方受污染了你还能飞到另外一个地方，而我却只能呆在这里。”小雨无可奈何的说。

小燕子悲愤的说：“人类难道不知道是大自然抚育了他们，他们难道不应该和我们一起保护大自然吗?”小燕子越说越激动!

小鱼的情绪也波动起来，忧心忡忡的说：“地球是我们共同的家园，我们大家应该一起呵护它!

小鱼又说：“我们虽然无法改变环境，但我们可以改变自己的心情!”小鱼说完尾巴一翘就游走了。

小燕子若有所思的想着刚才小鱼说的话······

[关于环境和污染作文400字

The environment is very important to human beings, but some people dont care for the environment, also do not know the importance of environment for human.

You see, many people dont care for the environment, they throw garbage everywhere, some people think: what is a garbage? However, many a mickle makes a muckle, and neighborhood became a dump the most beautiful place. Some people cut trees to build houses dig mountain, beautiful hill into desert and house. Some people dont have time to cook, just walk outside in the fast-food restaurant to buy rice, I eat, after dinner they also put the disposable lunch box, disposable chopsticks thrown to the ground. Some people in order to display their own home is very rich, driving a car on the road around. They didnt realize that both environmental pollution and waste of energy. Some factories take some sewage, smoke into the rivers and the sky.

For the sake of our environment, for the sake of our life, I want people to throw garbage into the trash can, little cut down a tree much afforestation, try to go home for dinner. Will exhaust waste water is introduced into the ground, dont show how rich, attention should be paid to energy conservation and emissions reduction.

Believe in you in the near future, with the help of our city will be more beautiful!

环境对人类十分重要，可是有些人不爱护环境，也不知道环境对人类的重要性。

你看，许多人都不爱护环境，它们随地扔垃圾，有些人认为：一个垃圾算什么?可是积少成多，小区里最好看的地方成了垃圾站。有些人为了建房子挖山砍树，美丽的小山变成了沙漠和房子。有些人没时间做饭，就在外面快餐店买了饭一边走一边吃，吃完饭后他们还把一次性饭盒，一次性筷子丢在地上。有些人为了展示自己家里很有钱就开着跑车在路面上到处跑。他们没有意识到既污染环境又浪费能源。有些工厂将一些污水、浓烟排入江河和天空。

为了我们的环境，为了我们的生活，我希望人们可以把垃圾扔进垃圾桶，少砍树多造林，尽量回家吃饭。将废气废水引入地下，不要展示自己多么有钱，要注意节能减排。

相信在大家的努力下不远的将来，我们的城市会更美!

Dear John,

Im glad to hear from you. Now let me tell you something about our city. Nantong is trying to set up a national civilized city. We middle school students are also doing some things for it. We are all polite to our teachers. (In class, we listen careful to them./When we meet them, we always say hello to them./…)We also respect the old. For example, we help them cross the streets.

We are always ready to help each other.(When one has difficulty with his studies, others will help him at once./...)We often show our love to those in trouble. Last month, the students of my class donated money to the earthquake-hit areas.

Besides, we plant trees to protect the environment and make our city more beautiful.

Nantong is my hometown. I will do my best to turn Nantong into a civilized city.

夜晚，明亮的路灯、大楼上的装饰灯、汽车灯光、广告牌的灯光以及公共设施的灯光等都会造成光污染。白天，我们同样会受到光污染的侵扰，如：楼房上的玻璃和大理石等做成的外立面，对日光的反射也会影响我们的生活。你可能会有疑问，那么就请带着疑问看看光污染带给我们的危害吧。

不适当的照明会让我们感到烦躁，我们的生物钟一直按照日夜循环的自然规律在运转，不论是新陈代谢、心率还是体温，都和生物钟息息相关。在它的指挥下，我们在白天精神百倍，而到了晚上就要睡觉，所有器官的活动同时也会减速休息。试想，本来是晚上睡觉的时间，可是由于过度光照的影响，生物钟发生错乱，误以为是白天，它的活动就不正常，那么我们的身体肯定会受到影响，如心情烦躁、睡眠障碍、头疼等。

不适当的照明致使天文台被迫搬家。日本东京的天文台自1878年建成以来，曾多次搬迁，原因就是大型望远镜在光污染的影响下能观测到的天体已经寥寥无几了。现在，只有在没有光污染的偏远山区，才能看到满天的星星。

不适当的照明也是全球气候变暖的罪魁之一，全世界每年照明的耗电量在两万亿度以上，如果燃煤生产这些电会排放20亿吨的二氧化碳和6000万吨的二氧化硫，而全球变暖主要是二氧化碳造成的。除此之外，照明设备还会释放很多热量，这也是城市温度不断上升的一个重要原因。

光污染造成的负面影响如此严重，该如何补救呢？

首先，每个人都要有减少光污染的意识，积极参加环保活动。

另外，要设计更合理的照明工具，改善照明条件。还可以增加遮光罩，使需要光照的地方很明亮，又不会给周围环境造成光污染。减少使用玻璃、大理石等反光材料作为建筑物的外立面。

减少光污染刻不容缓，让我们行动起来吧！

Humans have only one earth, it is human beings rely on natural resources, people want to live a happy happy life, you must consciously to protect the natural environment, care for the earth.

However, in recent years, the earths environment is more and more bad: global warming, hurricane, heavy rain, such as frequent disastrous weather, infectious diseases such as SARS, bird flu, bring serious threat to human life and work and a lot of inconvenience. These are the people constantly "damage" the result of the earth. Large forests have been cut down, green green hill was digging, beautiful grassland into desert, the clear river water turbidity. Trees less, castle peak bald, grassland drought, water dark and make people living environment deteriorate, breathe the air, living environment "occupied" by many harmful things, the virus will take into the body of people, we human beings will suffer from some terrible diseases.

A few days ago, I read in the newspaper that a cartoon: a man sitting on a tree, is he sitting on the branch. "Hum, really funny." Some people may think so. Dont you have to think of it, this is just a funny cartoon? It is just in our? Dont you see, it is warning us: human in the damage to the environment at the same time, also in imperceptible to hurt yourself.

When you walk in the street, if you want to spit, what would you do? If you chose to spit on the ground, you ever think that you hurt yourself? Phlegmy contains a lot of bacteria, when the sun will reproduce and spread. Also, when you cut down a tree, when you cut a piece of grass, when you pour the dirt into rivers, dont you think it is in the destruction of the environment, "injury"?

Proverb is well said: ", predecessors trees descendants cool, "predecessors gave us large tracts of forest and green space, we leave behind is what? Is bare desert, or the thick forest, you must choose the dense woods. What hesitate, let us together voluntarily protect the environment, good care environment, consciously consciously afforest environment, improve our living environment, create a better future!

人类只有一个地球，它是人类赖以生存的自然资源，人们要过上幸福美好的生活，就必须自觉地保护自然环境，爱护地球。

然而，近几年来，地球的环境却越来越恶劣：全球性气候变暖，飓风、暴雨等灾害性天气频繁出现，“非典”、禽流感等传染性疾病时有发生，给人类的生活和工作带来严重威胁和许多不便。这些都是人们不断地“伤害”地球的结果。大片的森林被砍伐，碧绿的青山被挖掘，美丽的草原成荒漠，清澈的河水成浊流。树林少了，青山秃了，草原荒了，清水黑了，使人们生存的环境变坏，呼吸的空气变差，生活的环境被许多有害的东西所“侵占”，病毒就趁机钻进人们的体内，我们人类就会患上一些可怕的疾病。

前几天，我在报纸上看到这样一幅漫画：一个人坐在树梢上，正在砍他坐着的那根树枝。“哼，真好笑。”有些人可能会这么想。难道你就没有想一想，这仅仅是幅好笑的漫画吗?它不正是在讽刺我们吗?难道你就没有悟到，它在警告我们：人类在破坏环境的同时，也在不知不觉地伤害自己。

当你走在大街上，如果你想吐痰，你会怎么做呢?如果你选择了吐在地上，那么你想过没有，你在害自己吗?一口痰含有大量的病菌，当太阳着时就会繁殖、传染。同样，当你砍伐一棵树，当你挖掉一片草，当你把脏物倒进河流，难道你没有觉得这是在破坏环境，“伤害”自己吗?

俗语说得好：“前人栽树，后人乘凉”，前人给了我们大片大片的森林，绿地，我们留给后人的是什么?是光秃秃的荒漠，还是茂密的树林，你肯定选择的是茂密的树林。那还有什么犹豫的，让我们大家一起自觉保护环境，自觉爱护环境，自觉绿化环境，改善我们的生活环境，创造美好的未来!
