世界环境日活动方案英语作文(20篇)

今年4月23日是第21个“世界读书日”，为了吸引更多的读者加入到我们“好读书、读好书”的行列里来，我校图书馆开展了读书月系列活动，昨日，如火如荼的读书月系列活动达到高潮。

4月23日下午，图书馆广场开展了一场以“走进阅读世界，共享阅读快乐”为主题的读者签名活动，众读者参与积极性极其高昂，一度将签名台围得水泄不通。

紧接着图书馆文学书库举行了“书库寻宝”比赛，参赛者按比赛要求和规则在指定时间内到书库找出指定书籍，找得又快又准确者获胜。报名者众多，图书馆工作人员根据先来后到的规则，最后选出28名参赛者，每名参赛者需要在文学书库里找出比赛所列的五本书，给予的书目顺序是打乱的，目的在于考察参赛者的细心和对图书查找的熟悉。大赛评选出一等奖一名，二等奖二名，三等奖三名。一等奖获得者在交流寻宝心得时说到她的获胜诀窍：她拿到书目并没有像其他参赛者一样第一时间冲进书库，而是仔细观察所给书目，发现书目的乱码后立刻将所给书目按顺序重新排列――排列后，她立刻发现所给书目其实很容易找到。文学书库图书书架共分五排，而所给书目总共五本，于是她大胆假设每排一本，实践后发现果然如此，因此她不到三分钟就完成了所有图书的寻找，将第二名远远甩在身后。

比赛结束后，现场气氛热烈，参赛者和观众仍然舍不得离开图书馆，还在图书馆工作人员的组织下，支援图书馆的搬书活动――这应该是素来安静的图书馆最热闹的一刻了。

读书月活动已接近尾声，然而读书月活动掀起的好读书氛围却延续了下来，上千读者积极参与了此次活动。本次读书月活动将以4月30日截稿的读书征文比赛来结束，希望各位读者踊跃参与征文比赛，分享自己的读书心得。

People plant a great number of young trees in the mountains.When the trees grow big and tall enough,they are cut down by workers and carried out of the mountains to the paper mill where fine paper is made from wood.Then it is taken to every corner of the country and used for different purposes.Some people use paper to copy writing,others use it to write something such as letters,reports and articles.When paper turns out to be of no use,the waste paper is collected and retreated in the recycling factory before being put into use again.

At present, 60% of the country in the world face the shortage of water, 20% of the population is difficult to get clean water, 51% of the people do not have access to sanitary water. This is caused by what? Is, that we are causing ourselves now factories and sewage in our life, not by processing is out. This is not proof of that? According to research, each 1 cubic meter of sewage discharge, 14 cubic meters of natural water pollution. Think of it, this is what a terrible number?

In the discharge of smoke in the factory, we dont know the smoke is atmospheric pollution? Scientists have found that there are at least 100 species of air pollutants produced great harm to the environment, directly affect peoples health.

在21世纪的今天，人类的科学经济发展已经达到了很高的水平。然而我想问：你们有没有意识到人类的活动对环境会造成怎样的影响呢?

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失，使许多地区成为沙漠。人类的活动范围在不断减少，这不可怕吗?

人类除了破坏森林之外，难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性，目前世界上60%的地区面临供水不足，已有20%的人口难以得到清洁水，51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的，现在的工厂及我们生活中的污水，没有通过处理就排出去。这不是最好的证明吗?据研究，每排放1立方米污水，就污染14立方米天然水。想一想，这是多么可怕的数字?

在工厂排出的浓烟里，我们不知道浓烟是污染大气的吗?科学家发现，至少有100种大气污染物对环境产生极大危害，直接影响人们的健康。

难道我们想在这种环境中生活吗?当然不想;那让我们用行动来证明吧!我们可以从我做起，从现在做起，从身边做起。树立爱自然、爱护环境的意识吧!来做宣传环保的使者!让我们一起为保护环境行动起来吧

Every year on October 4th is the World Animal Day. It is proposed by the Italian monk St Francis in 12th century. He lives in the forests of Assisi Island for the long time, building a good relationship with the animals. So he asks people to express thanks to the animals on October 4th. He sets a good example for our human beings about how to deal with the relationship with animals. In order to memorize him and what he does, we make October, 4th to be World Animal Day. Nowadays, people from all over the world will hold various activities to celebrate on that day.

每年的十月四日是世界动物日。它是由意大利修道士圣弗兰西斯在十二世纪提出的。他长期生活在阿西西岛上的森林中，与动物建立了良好的关系。所以他要求村民们在10月4日这天向动物表示感谢。他为如何正确处理与动物的关系树立了一个很好的榜样。后人为了纪念他和他所做的，我们把十月四号定为世界动物日。现在，在那一天来自世界各地的人会用各种活动来庆祝这一节日。这一节日的目的在于提醒人们关爱所有的动物，与他们建立和谐的关系。

Every year on April 22 is earth day, just as its name implies earth day is called on everyone to protect the earth. But you touched his conscience think how many people?

The earth mother is 4.5 billion years old, as early as 500000 years ago and gave birth to the human, mom has been with the sweet milk raising us, until now. The mothers body of castle peak, green trees, have ocean, have lawns and the forest. What a beautiful and great mother!

As everybody knows, the earth only plants can absorb carbon dioxide and breathe out oxygen. Scientists have to experiment and calculated 3 tree 1 day to absorb carbon dioxide equivalent to 1 adult 1 day of exhaled carbon dioxide. According to this calculation, plant is too important to human beings. So, we must protect plants. If I were a small tree, I want to those who only know building a house, build factories, do the people of furniture and those deforestation advice: please dont disorderly cut down trees, we also dont mess on our grass brothers again. Otherwise, our family will be cut out, clear-cut, crushed to death. By then, the whole earth will be a world of carbon dioxide, a direct threat to the earth mother and her thousands of children and grandchildren live! Therefore, we must strive to stop the public nuisance and private to harm. Also, we have a large number of plant trees, clean air, green our earth mother!

We should not only protect the earth on earth day day, and should treat every day as the world earth day, every moment to protect our earth.

每年的4月22日是世界地球日，顾名思义地球日就是呼吁大家保护地球。但是大家摸着自己的良心想想有多少人做到了呢?

地球妈妈已经45亿岁了，早在50万年前便生下了人类，妈妈一直用那甘甜的乳汁抚养着我们，直到现在。妈妈的身上有青山，有绿树，有海洋，也有草坪和森林。真是又美丽又伟大的母亲啊!

大家都知道，地球上只有植物才能吸收二氧化碳，呼出氧气。科学家曾经实验并计算过3棵树1天吸收的二氧化碳相当于1个成年人1天呼出的二氧化碳。照这样计算，植物对于人类实在是太重要了。所以，我们一定要好好保护植物。假如我是一棵小树，我要向那些只知道盖房子、建工厂、做家具的人们和那些乱砍乱伐的人们提出忠告：请不要再乱砍伐我们树木了，也不要再乱践踏我们的小草兄弟了。否则，我们的家族就会被砍光、伐光、踩死的。到那时，整个儿地球将会成为二氧化碳的世界，直接威胁到地球妈妈和她千千万万个子孙后代的生存!因此，我们必须下大力气去制止这些公害和私害的发生。而且，我们还要大量植树，净化空气，绿化我们的地球母亲!

我们不仅要在世界地球日这天保护地球，而应该把每天都当作世界地球日来看待，时时刻刻保护我们的地球。

Environmental Pollution I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why？ ——Fresh air is getting less and less in Japan， and so is it in the U. S. A. In fact， environmental pollution is a very serious problem the whole world is facing. it is mainly caused by the waste products released from artificial substances， industrial production and increased consumption of goods. Bedsides， the use of chemical substances in agriculture also causes environmental pollution. Look at the sky， you can see that dense smoke is being released from the high and big chimneys；

those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons f waste products are heaping around us. How to change this condition？ More and more countries are trying to work out some effective means to bring it under control， but no great success has been made.

空气混浊，河水黑臭，森林锐减，酸雨、噪音、沙尘肆虐……

环境破坏，谁是罪魁祸首?

面对污染，谁能独善其身?

良好的生态环境需要政府、企业、社会和每个公民的共同努力。环境质量的改善，不仅依赖行政、经济、法律、教育等途径，更重要的是，在于唤醒广大民众的参与和保护意识，在于公众将绿色生活的理念践行于日常的点滴行为之中。今年环境日，中国主题为“践行绿色生活”，陕西省主题为“绿色生活，从我做起”。

“绿色生活，从我做起”，不是口号，是行动!

让我们节约资源，减少污染

节约纸张，提倡双面使用，减少纸张消耗。

节约用电，随手关闭电源，外出时及时切断电源。

节约用水，珍惜每一滴水，随手关闭水龙头，合理使用供水系统，循环利用水资源。

让我们绿色消费，环保选购

倡导勤俭节约的消费观，培育简约环保的生活理念，抵制和反对各种形式的奢侈浪费、不合理消费。

购买简单包装的商品，拒绝过度包装的商品，拒绝包装浪费。

超市购物，自带购物袋，拒绝白色垃圾。

选购环保节能产品，选购绿色产品和绿色食物。

让我们重复利用，循环再生

自觉形成资源循环利用的理念，尽量一物多用。

进行垃圾分类和资源回收，节约使用不可再生资源。

让我们低碳环保，绿色出行

Schools organize sport activities, such as ball games and races.. This is to allow the students to participate and to allow them to horn their ball skill However, people have different views about these activities. School has the intention that the sports activities are good to the health of the students and can reduce the possibility of illness. At the same time, the students can develop the spirit of team work and perseverance, and as a result, they will be more attentive in their lessons. On the other hand, most students think that these activities are a complete waste of time. If they can use the time in learning their subjects instead of playing football, theyll make great progrein their lessons. They reasoned that they will feel very tire after these activities, which has a bad effect on their learning efficiency. I personally think that sports activities should be supported. However, we can reduce the time of these activities so that they will not affect our lessons. We may feel tired after these games but we can learn to relax ourselves by listening to music or something else so as to rejuvenate ourselves. In conclusion, health is the foundation to all work. The only way to keep fit is to exercise

Nowadays,our world is in great danger.There are air pollution,water pollution and so on.So Its important for us to protect the invironment .We shouldnt throw rubbish everywhere.We can go to school by bike insdead of taking a bus.And we shouldnt draw on the wall.In a word,Lets protect our invrionment together.

The earth mother as the cradle of life, human like a spoiled child of the earth. She give us everything we need for life leave her, we will get nothing. Beautiful living environment is the basis of which we live, but now, our environmental protection consciousness is more and more weak. Though, we all know that protect the environment, but not the property of the consciousness of earth, destroy the originally beautiful environment; In fact, in life, as long as pay attention, everywhere can be environmental protection.

In those restaurants everywhere can see around us, the boss in order to achieve "health" standard, and unconsciously extensive use of wooden chopsticks that were made from wood; Cost is huge, hits the verdant trees with bangs fall, only the birds were forced to leave, a group of a group of lovely animals homeless again, but as they didnt see, originally natural ecological environment destroyed by them, just like that. Not only did not have the forest, and animals are not spared. Recently, some cantonese put smart cute little monkeys alive opened the brain had his head down, they looked at each cute little monkey innocent dead, but still, this is what a horrible thing!

We as the master of the earth, if you dont cherish everything now, that this beautiful environment will leave us early. At that time, we will face catastrophe, the earth will be scarred, and hurt; So we should do owners should do, well protect our survival environment, do not deliberately to destroy, remember: to protect the environment, is to protect the future of mankind.

地球母亲就像是生命的摇篮，人类就像是地球的骄子。她，给予了我们生活所需要的一切离开她，我们就一无所获。美好的生存环境是我们赖以生活的基础，可是现在，我们保护环境的意识却越来越淡薄了。虽然，大家都知道保护环境，但却不自觉的掠夺地球的财产，破坏原本美丽的环境;其实，在生活中，只要留心，处处都能环保。

在我们周围的那些餐馆中随处可以看到，老板为了达到“卫生”的标准，而不自觉的大量使用那些用树木做出的木质筷子;为此付出的代价是巨大的，一棵棵青翠的树木随着巨响而轰然倒下，一只只鸟儿被迫离开，一群又一群可爱的动物无家可归，可他们却当作没有看到，原本自然的生态环境就这样被他们破坏。不仅森林没有了，而动物也是不放过。最近，一些广东人竟然把机灵可爱的小猴子活活的把头打开把脑子吃了下去，他们看着一只只可爱的小猴子无辜的死去，却还是无动于衷，这是多么令人发指的事呀!

我们身为地球的主人，如果不珍惜现在的一切，那这美好的环境一定会早早的离开我们。到时候，我们会面临灾难，地球也会伤痕累累，而受到伤害;所以我们应该做到主人应该做的事，好好的保护我们生存的环境，不要蓄意的去破坏，要记住：保护坏境，就是保护将来的人类。

I turned pale with fear, quickly get out, I was happy mood was thrown to the outside of the nine days into the sky, I hate people who litter, only now is, they put a good road. I went on weakly, those people if one

Good environment can make people feel happy and fit 。 To improve the environment means to improve our life。

We should plant more trees and flowers around us 。 We shouldn’t cut them down 。 We should stop factories from pouring waste water into the river and waste gas into the air。

Whenever we see litter on the ground ， we should pick it up and throw it into dusbins。 Never spit in public。 Don’t draw on public walls。 It’s our duty to protect the environment。

“自己叠被子呀，自己梳头发呀，不再麻烦你呀，我亲爱的好妈妈……”3月21日，在县第三双语幼儿园各个教室内，传出孩子们整整歌声。

今天是“世界儿歌日”，吉木萨尔县第三双语幼儿园组织全园小朋友们学唱儿歌。小朋友们在老师的伴奏下，先后演唱了《小燕子》、《春天在哪里》、《不再麻烦妈妈》等童谣。“小孩子们特别喜欢唱儿歌，律动性强的歌曲，配上些简单动作，学得特别快!”负责为孩子们伴奏的陈丽媛老师说道。

Protection of the Environment Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive. We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products arestill put into rivers. We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycie them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

Smoke has something for people in poor health, nicotine.

Nicotine in a cigarette can kill a mouse, 25 g of nicotine in cigarettes can kill a few cows, 40 to 60 mg of pure nicotine can kill a person.

Smoke harm to people is how great! So we cant smoke. Stop smoking, the benefit of future generations.

烟里有一种对人身体不好的东西——尼古丁。

一枝香烟中的尼古丁可以毒死一只小白鼠，25g的香烟里的尼古丁可 毒死几头牛，40至60毫克纯尼古丁可以毒死一个人。

尼古丁的危害也是相当的大，它可以引起胃痛或其它胃病;还会使人引起心律不正诱发心脏病;严重的还可能引起癌症的爆发。

香烟是隐藏在我们身边的隐形杀手，是大家所应警惕的。

据科学家测定，烟草中含有数百种复杂的化学成分，大部分对人体有害，其中焦油、尼古丁、酚类、醇类、酸类、醛类等40种是有毒和有致癌作用的物质。烟在点燃后，所产生的烟雾，包含了烟草中所有的化学成分，同时比烟草本身又增加了一些有害物质，如一氧化碳和烟焦油等。这是因为除烟草本身外，在制成卷烟的过程中，要在原料中加入一些可可、甘草、糖、甘油、乙二醇等调味、湿润、产香、助燃物质。这些添加剂虽然本身无害，但在燃烧过程中却起了变化。例如，在鼠背涂上可可燃烧后产生的烟油，可长出皮肤瘤。甘草中的甘草酸在燃烧后，与其他成分化合，可生成有致癌作用的多环芳烃。糖与烟草一起燃烧后增加了焦油量，而糖燃烧后的产物是烟中的一个重要致癌物。甘油和乙二醇在燃烧后的物质，不但可能使吸烟者患膀胱癌，而且所产生的丙烯醛可抑制气管和纤毛分泌物从肺内排出，从而增加患气管炎和肺气肿的机会，并使患有这两种病的人病情加重。

烟对人的危害是多么大啊!所以我们不能吸烟。杜绝吸烟，造福后人。
