保护地球英语作文20句【经典20篇】

在公园里，在电视上，在公路上，都看到保护绿色，保护自然的公告。那是为什么呢？原来，那是为了呼吁人们爱护我们的家园——海南。

绿色是人类的服务员。春天，它会向人们报告春，让人感到新的生命发芽了；夏天，浓荫蔽日，它为人们挡住炎炎烈日。这时，绿色浓得可爱，让人感到生命力的顽强。秋天，之所以结出累累的硕果，那是因为绿色在春天汲取了自然的养分；冬天，是绿色在孕育着新生命的种子。

绿色植物是人类的恩人，它吐出氧气，让人们吸收新鲜的空气。森林是大自然的清洁工，在保护环境方面，森林的生态效益大大高于直接经经济效益。海南，四周环海，它就是靠森林的保护，才不会被汹涌澎湃的海水淹没的。像古巴比伦一样，由于人们长期滥代森林、过度放牧、陡坡种植，使两河上游的高原发生了严重的水土流失，所以才被泥沙掩了。你看，难道这不正是大自然的惩罚吗？

是的，绿色和人类有着密切的联系。如果谁惹怒了它，它也会无情地惩罚你。绿色对于海南至关重要。思格斯说：“不要过分陶醉于我们对自然界的胜利。对于每一次这样的胜利，自然界都报复了我们。”的确如此，它为海南创造了巨大财富，装点了海南，点化了环境，有了绿色，一切都生机勃勃。可人们不断破坏，绿色迅速消失。如果失去森林，地球生态系统就会崩溃，人类就将无法生存。为了我们的生存，我们的财富，我们的南方明珠——宝岛海南，我们必须保护着宝贵的绿色！

很多人都知道“绿色生命之源，是人类赖以生存的条件”。但又有多少人是有一颗保护绿色的心呢？我觉得，在我们海南，没有几个人是真心真意地热爱大自然，保护绿色的。因为在我们身边，都会看到成千上万的人都是为了自己的利益，肆意破坏身边的自然绿色，为了获得财富，他们不惜损失海南最宝贵的绿色来达到自己的目的。但他们又何曾想过，他们失去的何止是财富，他们更在损害自身的健康！

用心去感悟自然吧！心动不如行动，为了海南明天的辉煌，首先从经绿色着手，一起手拉手去保护地球，给地球一个清新，给人类一个绿色美好的家园！

[作文保护地球500字

今天是4月22日，是“世界地球日”，人类历史上的第一个“地球日”，是1970年的今天由美国哈佛大学法学院的一个刚满25岁的学生——丹尼斯·海斯在校园发起和组织的，如今他被誉为地球日之父。

Today is April 22nd, is the "World Earth Day", the first "Earth Day" in the history of mankind, is today in 1970 by a USA Harvard University law school, just over 25 years old students in Campus -- Dennis Hays initiated and organized, but now he is known as the father of earth day.

也许有同学认为，关心地球环境是大人们的事，或者说这是环保部门的事，与我们无关。其实，大家都知道，我们所有的人都居住在同一个地球上，都是地球村的村民，地球环境与我们每个人的生活是息息相关的。下面我以我们生活中的必需文具──纸为例，说明节约用纸、合理用纸与保护地球环境的关系。

Maybe some students think, to care for the earth environment is the thing, or that it is a matter of environmental protection departments, has nothing to do with us. In fact, we all know, we all live in the same earth, all the villagers, the earths environment and our lives are closely related. Below I to the necessary stationery in our lives -- as an example to illustrate the relationship between paper, save paper, paper and reasonable to protect Earths environment.

我们每个人每天都在用纸，用各种各样的不同类型的纸。你统计过吗?你每天要用多少张纸?一星期要用多少纸?一个月乃至一年要用多少张纸?统计之后，我们会发现这一结果是非常惊人的。

Each of us every day in the paper, using a variety of different types of paper. Your statistics? You every day how much paper? How much paper for a week? A month or even a year how much paper? After the statistics, we will find that this result is astonishing.

一张纸从何而来?造纸的原材料主要是由树皮等植物的纤维“变”来的。一棵树往往需要长几年、几十年才能被人类利用。而人类有时却很无情，电锯声中，几十年长成的大树轰然倒地。那些木材，被运往造纸厂，变成了一张张纸。纸给人类的生活带来了许多方便，但同时，人类对纸张的过度使用也给森林资源造成了极大的不良影响。大家知道，大面积的森林可以涵养水源，防止水士流失，净化空气，森林是制造氧气的“工厂”，森林能够吸收有害物质，森林能够保持水土。可见，节约每一张纸，对保护地球环境至关重要。

A piece of paper from why and come? Raw material for paper is mainly composed of bark and other plant fibers "change". A tree often require long years, decades to be human use. But sometimes people are unkind, chain saws, decades old growth trees crashing to the ground. The wood, was shipped to the paper mill, turned into a sheet of paper. The paper gives human life has brought a lot of convenience, but at the same time, the paper also human excessive use of forest resources caused great negative impact. As we all know, a large area of the forest can conserve water sources, prevent soil and water loss, purify the air, forest oxygen is produced "factory", forest can absorb harmful substances, soil and water conservation forest can. Visible, saving every piece of paper, is essential to protect the earths environment.

尊敬的深圳市环保局领导：

你们好！我是**市南山实验学校六年级的一名学生。

如今十分发达的地球，但是却有十分重大的隐患，这都是人为制造出来的：大肆砍伐树木、建立化工厂、胡乱排放有害液体。"对人类威胁较大的气体，世界每年的排放量达6亿多吨……"看见这一组组令人触目惊心的数字，真是叫人吃惊何感想？从2300万年到1800万年前森林古猿的出现到现在人类高度发达的文明时代，对于每个人从未停止过的索取，大自然都是"有求必应"的，这更滋长了人类的贪欲。

环保局的各位领导，以下是我为这个美丽的城市所提出来的建议，供你们参考！

第一，我们要做到讲究卫生，因为那样才能够保护环境！当然就是不能随地吐痰，不乱扔垃圾，不在公共场所吸烟，不制造噪音。

第二，我们要保护自然环境，那样万物才能共同生存在一个美好的家园。我们不但自己要做到，而且还得以自己的力量来提倡身边的人不猎杀、不使用珍稀动物和受保护的动物，关爱与保护野生动植物；植树造林，爱护我们身边的每一寸绿地、每一株花草、每一片树木！现在我们部分地方已经做起了这个活动项目："分类回收循环再用".我们不能乱丢弃废电池、废塑料等垃圾、废物；而是要将垃圾分类投放，变废为宝，使资源循环再生，造福人类！

第三，我们一定要做到最重要的一个：节约资源减少污染！节水为荣，随时关上水龙头，千万不能浪费我们的水资源！

以上就是我为这个美丽的城市所提出来的建议，希望环保局的领导能参考参考我的建议。

希望我们的城市能越来越美丽！！

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。

河水是地球母亲的血管，因此一定要好好保护河水，不能让母亲的血液受到污染，血管被堵塞。中华民族的母亲河--黄河原本是一条清澈的河流，但流经黄土高原时，因为缺少树木，遍地是黄土，所以河水受到沙土的严重污染，变成了黄色。同时河水也是一些小鱼小虾等小生物的领地，如果河水被污染，就会夺去许多小生物的生命。我们应该阻止人们往河里扔拉圾、排污水。

空气是人类和其它生物赖以生存的，地球上的生物一分钟也不能离开它。可工厂向外面排出的浓烟大大污染了空气，有的人吸了被污染的空气以后，时常咳嗽，嗓子发干、发痒、发痛，甚至引发咽炎。所以，对污染空气的事我们应一律拒绝。

当雪白的墙壁被涂抹时，你的心情会怎样呢?这种行为既不美观，又不道德，就像墙上长着一大块牛皮癣，哪个人希望自己身上长一大块牛皮癣呢?我们如果遇到这种情况时，应及时清理。

地球是我们人类共同的家园，我们应该保护环境。

一天，月亮姑娘和星星们正在银河系里玩耍。突然传来了一阵呜呜的哭声，她们连忙赶过去，看到地球姐姐正在哭泣，都过去安慰。

月亮姑娘问地球：“姐姐，您为什么哭呀？遇到什么伤心的事了吗？”这时，月亮姑娘看到地球满身都是伤，就追问道：“您的身上怎么全是伤啊？您不是有很多孩子——人类吗？”地球有气无力地说：“还说呢，就是人类害我这样的，呜呜呜，我该怎么做呀？”一颗小星星插口道：“哪他们是怎么伤害你的呢？”地球说：“他们这些不孝顺的孩子，为了自己生活的舒坦，把保护我身上的树都砍光了，还无时无刻的在让化工厂排放有污染气体。所以我的身体受到了极大的伤害。”一颗淘气的小星星说：“那您就应该给他们点厉害，让他们知道身在福中不知福是什么后果！”地球说：“可他们是我的孩子呀，我怎么忍心呢？”月球想了想，兴奋的说：“对了，你不是还有净化空气的大海还有长江黄河吗？环境怎么还会被污染呢？”地球长叹了一口气，说：“他们被污染得更厉害，人们随意把污水倒进大海里，长江黄河也是苦不堪言哪！唉！”这时，刚好龙卷风和台风路过这里听到地球与月亮的对话，高兴极了，就准备趁地球现在身上没有任何保护环境的东西，去地球上搞破坏。他们说干就干，马上分头闯进了地球，龙卷风把街道上的石子和垃圾高高卷起，玩够了就又扔下去，把人们居住的房间的房顶都掀了起来。而台风则闯进了大海，在海上胡作非为，大风把沿海居民的家都吹垮了。“如果以前有树的话，”一个逃生的人说，“那就不会发生这样的事了。”可是后悔已经来不及了。正在这时，地震和暴雨来了，他们看到台风和龙卷风玩得很开心，就上前一起捣乱。人们四处逃窜，可是当龙卷风和台风来到一个村子的时候，不知看到什么东西，连忙逃窜了，地震和暴雨这两个跟屁虫也跟着他们跑了。

人们喜不自胜，就都凑上去看情况，他们看到了一排排大树和一条条清澈的小河，再往进走，他们看到了一群男女老少正在植树，都羞愧地低下了头。人们这才体会到保护环境的重要性。

回到家后，人们自发的组织植树，还积极的捡拾垃圾，直至排放污染气体和污水，地球又焕发出了勃勃生机。台风、龙卷风等自然灾害都不敢入侵了。

地球妈妈十分开心，一旁的月亮也很高兴，她说：“呵呵，这下可好了，人们终于知道保护环境的重要性了。姐姐，您有什么愿望呀？”地球满怀憧憬地说“我希望人们可以永远懂得‘环保’二字的意义。这样我就可以永远这么舒服了。”

Boundless sea to look forward to, give people the beauty, give a person warm motherly love.

The sea is like a poem; it jumps; like a picture, rich in meaning; and like a symphony, vast and mighty...... It is like a mirror; sometimes calm, sometimes filled with rage, overwhelming, to sail the boat overturned. In my mind, the sea is blue world, is also the cradle of life. Pregnant with many free and small life. The sea is so mysterious, so charming!

Now the sea has changed. The sea is no longer clear, it becomes muddy and dirty. Washed up on the beach, left is no longer alive and kicking the fish shrimp, instead of the piles of rubbish, but also mixed with a lot of dead fish shrimp, stinking. Why is that? Its all because of us. When people admire the beauty of the seaside, they throw the foul rubbish into the sea. There are also people living on the beach, the toilet drain pipe to the bottom of the sea. Whats worse is that the factory waste water flows into the sea in large stocks, and the sea is dyed in a strange color. Led to the birth of a lot of lack of brains, low IQ infants, our next generation - bright eyes [voice tender], the face of the next generation of red, will never see the beautiful blue sea.

Someone once did an experiment. He compared a basin of water to the ocean, and dropped a drop of ink into the sea. Immediately, the ink slowly spread out, became shallow and disappeared. The sea water was almost as clean as ever. If the ink kept dropping, the color of the sea would be deeper and darker, and eventually it would become a basin of black water. 6 billion people on the earth produce large quantities of living waste water and industrial pollution every day. Like ink, it has been injected into the clear sea water. It has become a polluted lake.

To the health of our human beings, to see the beautiful blue sea for our children and grandchildren. Let us act now, love the ocean as much as we love life, and love the common blue home of mankind.

Protecting the Environment

In the last several decades, our earth has been extremely polluted, such as air pollution, water pollution, noise pollution and so on. In recent years, the extreme weather becomes more and more frequent. Winter gets colder and summer becomes hotter and it rains more frequently. All of these warn us that protecting the environment is a serious and emergent event. As our general people, we should build proper lifestyle. We should pay attention to water and light saving. When we go out, we should firstly choose the public transportation. The most important is that we must realize that we can do a lot of things to protect our environment. Its our duty to make our home better. Let’s change from ourselves.

在过去的几十年里，我们的地球已经极度污染，比如大气污染，水污染以及噪音污染等等。近几年，极地气候越来越频繁。冬天越来越暖，夏天越来越热，还经常下雨。所有的这些都警示我们保护环境是一件严肃紧迫的事。作为普通老百姓，我们应该形成合适的生活方式。我们应该注意节约水电。出门的时候我们应该首选公共交通。最重要的是我们必须意识到我们可以做很多事情来保护我们的环境。使我们的家园变得更美好是我们的责任。让我们从自己开始改变。

[初中英语作文及翻译：保护环境

The survival of the earth is our home, its like mother, provide us with the resources and conditions of survival. We are the master of the earth, we should like to yourself to protect it.

Who wouldnt want to make their homes more beautiful, more beautiful? However, with the development of science and technology, more and more living garbage all sorts of multifarious, including most waste will cause environmental pollution. For example we commonly used battery, if you dont properly handle after use, it will cause a great environmental pollution. According to research, section button battery waste 600000 litres of water undrinkable. If each throw away a battery, then then, water, and will become a luxury.

So, in order to protect the environment, please put garbage sorting.

On June 1, 2008 in our country implements the "plastic limit order", the practice, to make our country save thirty-seven million barrels of oil a year. Plastic bags, this kind of thing for ordinary family ordinary but again, but you know, plastic bags is one of the main factors pollute the environment. Plastic bags with oil as raw material, not only consumes a large amount of resources, but also need 500 years to be natural decomposition.

So, in order to protect the environment, use less plastic bags, please.

As the owner of the society, to improve the earths environment, it is our duty-bound responsibility and obligation. If the world environmental protection, environmental protection, everyday everyone can create a new, beautiful world!

地球是我们赖以生存的家园，它就像母亲一样，为我们提供着生存的资源和条件。我们是地球的主人，我们要像善待自己一样去保护它。

谁不想让自己的家园变得更美好，更漂亮?然而，随着科学技术的发展，各种五花八门的生活垃圾越来越多，其中大多数垃圾都是会造成环境污染的。比如说我们常用的电池，如果用完后不进行适当的处理，那么将会造成极大的环境污染。据研究，一节废的纽扣电池能使60万升的水不能饮用。如果每人丢弃一颗废电池，那么到了那时，水，将成为奢侈品。

所以，为了保护环境，请将垃圾分类。

我国于2008年6月1日起实行“限塑令”，这一做法，使我国每年节省三千七百万桶石油。塑料袋，这种东西对于普通家庭来说再普通不过了，可是你知道吗，塑料袋却是污染环境的一大因素。塑料袋以石油为原料，不仅消耗了大量资源，而且还需要500年的时间才能被自然分解。

所以，为了保护环境，请减少使用塑料袋。

作为社会的主人，改善地球环境，是我们义不容辞的责任和义务。如果世界人人环保、天天环保，就可以创造一个崭新、美丽的世界!

Animals are our good friends, we should protect them, because a lot of animals is beneficial to human.

For example, I like little bees. It is very industrious, arrive every day, honey for the people.

I like the little green frog. It hid in the fields every day, as long as pests, will be the frog to eat into the belly.

I like the swallow. Its a beautiful singing voice, as long as the spring comes, they fly back from the south.

I like worms. It ran winding in the ground, turned out to be digging in to help the earth mother.

I like small gecko. Its tail special magical, broken can come back for yourself. Also can help mankind to catch mosquitoes.

Little friends, do you like the animals? So lovely small animals, we mustnt hurt it.

动物是我们的好朋友，我们应该保护它们，因为很多动物对人类有益。

比如，我喜欢小蜜蜂。它很勤劳，每天早出晚归，为人们采蜜。

我喜欢小青蛙。它每天都躲在田地里，只要害虫一来，就会被青蛙吃到肚子里。

我喜欢小燕子。它的歌声很优美，只要春天一到，它们就从南方飞回来。

我喜欢蚯蚓。它在地底下弯弯曲曲的跑着，原来是在帮助大地妈妈松土。

我喜欢小壁虎。它的尾巴特别神奇，断了能自己再长出来。还能帮助人类捉蚊子。

小朋友们，你们喜欢这些小动物吗?这么可爱的小动物，我们千万不能伤害它。

Everyone can do something for our environment. For me, I should try to save electricity in my daily life. For example, if I am the last person leave the classroom in the evening, I will always remember to turn off the lights. In order to protect our forests, I will use paper wisely. I should try to use both sides of paper whenever it is possible. I will not use things like paper cups and disposable chopsticks because they are made of wood. I believe that doing all these small things will improve our environment and help make our world a better place to live in.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

在这个美丽的蔚蓝色星球上，有着让人美不胜收的亮丽风景，有着让人目不暇接的名胜古迹，有着令人眼前一亮的神奇的自然景观。春天的明媚娇艳、百花齐放;夏天的绿多荫浓、烈日炎炎;秋天的瓜果飘香、色淡叶疏;冬天的银装素裹、万里雪飘，无不体现出欣欣向荣的和谐景象!“红花绿草满园栽，风送花香碟时来。”

然而，有一天，一个恶魔来到了这里，他卷着沙尘暴，挟着病毒细菌，带来了漫天的垃圾纸屑，他的名字叫——污染。

他将原本清澈见底的河流湖泊变得肮脏不堪，他将原本树木丛生的森林变得光光溜溜，他将原本茂密的草丛变成一块块荒地，他将原本清新凉爽的空气变得乌烟瘴气，许多动物植物不得不面临惨痛的决定：灭种!那些因为滥采滥发而失去家园的鸟儿，无助的在天空周旋，悲凉的看着那个破烂不堪的家，那些因为水质污染而无法继续生存的鱼儿，绝望的浮在水面上睁大眼睛望着天空，似乎在诉说着什么……

人们啊，请醒悟一下吧!不要再让那个恶魔继续猖獗下去了，请从身边的小事做起，善待身边的动植物，爱护身边的环境，让那个恶魔从这个地球上永远的消失到!要知道，世界万物是互相关联的，如果不善待环境，总有一天也会危及自身的生存!

庄子曾经说过“顺之以天理、行之以五德、应之以自然”当你捡起一片纸，你就为世界减少了一份污染;当你种下一颗树，你就为世界增加了一抹绿;当你回收了一块电池，你就为世界保留了一片肥沃的土地!也许一个人捡起一块纸没什么大作用，但如果每个人都捡起一块呢?也许一个人种下一棵树没什么大不了，但如果每个人都种下一棵呢?

不要整天大放厥词“我要保护环境!”光说不做是没有用的，让我们拿出实际行动，从身边的点滴小事做起。为了让河水继续清澈，为了让天空更加湛蓝，为了让动植物们重新拥有一个赖以生存的家，让我们一起“减少污染，行动起来!

亲爱的同学们：

大家好!今天我提笔写这一份建议书，是想针对保护地球，珍惜资源的问题，来向大家提一些建议。

众所周知，现在在我们身边，浪费资源的例子有很多：水龙头的水哗哗地流着，用水人却不知去向;电视机卖力地播放节目，房间里却空无一人;厚厚的本子被随手扔进垃圾桶，仔细看发现只是用了几面而已;富丽堂皇的饭店里，桌子上的“剩饭剩菜”竟然多数是只夹了一两筷子的美味佳肴。

因此，我诚恳地向大家提出以下建议：

一、洗手完要关紧水龙头。现在我们地球虽然有70%是水了，但可饮用的淡水很少，大多都是不可饮用的咸海水。

二、电视机不看了要关掉。电力资源也是有限的。想一想未来要是没有电了，那该有多可怕呀!

三、本子用过后如果还有剩余，可以用来当练习本，如果没有剩余，背面还能当草稿纸。纸是树做的，要用树就要砍树，砍树就会造成土地沙漠化。要避免土地沙漠化的方法就是少砍树，多植树。

四、饭店吃饭，吃不完的可以打包，别以为这样没面子，现在难道不是都在支持光盘行动吗?要知道餐桌上的饭菜来之不易呀!

以上是我提出的建议，也许还不够成熟，但是希望大家能参考一下。当然，我这微小建议如果大家能认真对待，每个人出一份力，那么，我们地球母亲的环境将变得更美好!

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

各位沈四小周边居民：

你们好！

众所周知，地球是我们赖以生存的家园，人类今天的发展与竞争离不开地球的帮助。有人曾说,地球是我们的摇篮，更是我们的母亲。我觉得这句话形象地道出了地球与人类之间相互依存的关系。然而，在科技飞速发展的二十一世纪，人们在享受物质财富的同时，有没有发现，我们身边的环境正在严重的恶化？

不错，南极臭氧层空洞、两极冰川融化、长江流量减少；水土流失、洪水泛滥、土地沙漠化……难道这样的生态灾难还少吗？汶川、玉树大地震，舟曲泥石流……这就是大地母亲向我们发出的警告。如果人类再不幡然醒悟，从身边做起，好好保护环境，那么最终的结果只能是走向灭亡，重蹈楼兰的覆辙。生态破坏、环境污染已经对人类生存发展构成了极大的威胁，也许在不久的将来，《2012》电影中的镜头就会成为现实。现在，很多人都举着“低碳节能，保护环境”的大旗，可真正付诸于行动的又有多少？因此，特向你们发出几点倡议：

1、 拒绝白色污染。不论到哪里购物（包括菜市场）都不要使用收费或免费的塑料袋，尽量自备布袋。因为这些塑料袋一旦被埋入地下，几千年都不会分解，其危害不亚于废电池。

2、 不乱扔垃圾。出门在外，最好带一个袋子，将自己用过的废旧物品放进袋子里，等找到了垃圾桶时再扔掉。

3、 实行家庭垃圾分类制度。用不同颜色的垃圾袋区分可回收和不可回收垃圾，再按其种类丢进垃圾桶，能给垃圾回收工作带来不少的便利。

4、 珍惜水资源。不将生活垃圾倒进河里；洗手擦肥皂时应该将水龙头关掉；淋浴时脚下放个水盆，积下来的水可以冲厕所，这样也能节约很多水资源。

5、 节约每一寸纸。复印资料或其它文件时，尽量采用双面复印的方法。虽说只是一面纸的问题，但天长日久，积少成多，一年下来就可以少砍几棵大树。

6、 节能减排。堵车时，如果队伍太长，就干脆将发动机关掉，既节约了汽油，又减少废气排放。

正所谓木本水源，一脉相承。我们的老祖宗给我们创造了这样一个良好的环境，我们就应该好好珍惜。希望你们采纳我的建议，珍爱地球，保护环境。

[珍爱地球保护环境初中生优秀作文

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 of 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.

It is the duty of every global villager; man just can not sustain his glorious civilization without a rewarding environment, which will be possible only if man makes considerable efforts to protect the environment.

Do you cherish precio us opportunities to volunteer in our joint efforts in environmental protection? Here is a great one not to be missed by any enthusiastic youth; Right next Saturday, our university is to run a publicity campaign to advocate environmental protection across the city. The University Students Union will be in charge of recruitment of volunteers. Lets join our hands and take action immediately.

Yours sincerely,

People like to modernize the building compared to the magnificent, then this embodies a high degree of spiritual civilization and material civilization of the building should stand in what kind of environment? If the sky filled with smoke, the earth vegetation and so on, this is the people of the modern society of it? No, no, it is the irony of history, this is the tragedy of mankind.

People live on earth, to survive, to develop, first of all have to rely on the earth, by mountains and water, there are grassland nature of the forest. But some people mistakenly believe that nature is inexhaustible treasures, so deforestation and species, dried Ze and fishing, and even by the natural punishment and not know. Year after year, the forest into a barren hills, oasis into a desert, resulting in the world every year, 2,000 hectares of farmland was swallowed by the desert. So go after a few years, the earth will be all occupied by the desert green, our children and grandchildren will not survive! A few years ago, the rural package to the household, coax the mountain into the wind, Chinas Wuchuan County, a township of nearly 2,000 acres of fir forest, cut in a week for the ground. Hearing this news, I have a headache, I am angry, the farmers doing so are too ignorant and too selfish. There are a lot of things that are doing the same thing: it is the smoke of the sky, so that the noise of high decibels can stimulate the nerves of the people.

In this regard, we should think deeply. Modern society makes us live better, modern science has also fully revealed the importance of environmental protection. Every honest citizen should have such a historical vision and sense of urgency: to build our country into an ideal modern power, we must do the development of economic and environmental protection simultaneously, to achieve economic development and social benefits of unity.

人们喜欢把现代化比作宏伟的大厦，那么这座凝聚着高度精神文明和物质文明的大厦应矗立在怎样的环境之中呢?如果天空烟雾弥漫，大地草木枯败等等，这是人们心中的现代化社会吗?不，不是，这是历史的讽刺，这是人类的悲剧。

人生活在地球上，要生存，要发展，首先就得靠地球，靠有山有水，有森林有草原的大自然。可是有人误以为大自然是取之不尽，用之不竭的宝库，于是毁林而种，竭泽而渔，连连受到自然的惩罚而不自知。年复一年，森林变成了荒丘，绿洲沦为沙漠，致使世界上每年有2000公顷农田被沙漠吞噬。这样下去经过若干年，地球上的绿地将全部被沙漠侵占，我们的子孙将无法生存!前些年，农村包产到户后，哄砍山林成风，我国务川县一个乡的近2000亩杉木林，在一周之内被砍为平地。听到这个消息，我头疼，我愤怒，这样做的农民太愚昧，太自私。还有很多正在干着类似务川的贻害子孙的事情：任滚滚浓烟弥漫天空，让高分贝的噪音刺激人的神经。

对此，我们应该深思。现代化社会使我们生活得更美好，现代科学也已充分揭示了环境保护的重要性。每个正直的公民，都应具备这样的历史眼光和忧患意识：要把我国建成一个理想的现代化强国，必须做到发展经济与保护环境同步，实现经济发展效益与社会效益的统一。

事实也是这样，几年前，大连污染严重，经过一系列的保护措施后，不仅使市容面目美观了，还带来了良好的经济效益，外商投资，中外合作等等，因此让大连成为现代化的大都市。

让我们伸出自己的双手，来保护自己的家乡，来建设自己的家乡吧

破坏环境的人们：

你们好!

我是一名普通的小学生，之所以要给你们写信，是因为想倡导大家要保护人类的母亲——地球。

最近，严重的雾霾笼罩了整个杭州市，天空变得灰蒙蒙的，这样，我们人类就成了雾霾的受害者，但你们想过吗?其实，这也是人类自己制造的!各种工厂排放二氧化碳之类的有毒有害气体，汽车排放尾气，使大气受到了严重的污染。人们常说：我们要保护地球。但为什么环境还不好呢?因为人们光说不做，为了眼前的利益失去了理性。因此，只有人类做好了，我们的天才会更蓝，水才会更清，空气才会更清新。我们要向你们提出几点建议：

1、尽量少排放有毒有害气体。

2、少开车，多骑自行车。

3、节约用水。

4、不随意砍伐树木。

做到以上四点并不难，只要用心，一定能行!保护环境，人人有责!我们共同为后代创造一个美好的生活环境!
