保护地球的英语小作文(经典20篇)

Nowadays environmental protection has become the first thing we have to do, because now the earths environment is under threat.

Now, we know that the earth has been warming, cold place has melted the ice, the water level becomes more and more high, let many coastal countries. More land desertification, disasters are hit, make our life is no longer so carefree.

First of all, we must start from the side.

Forests have been cut down, automobile exhaust emissions... The first will directly affect our lives, because they let we dare not breathe. So, the best way to deal with these problems is to drive less, ride bikes, and riding a bike is good for you! . But although it has been said that and said more than once, but why there are so many cars on the road? So, this method really, a bit not practical.

The simplest is to plant trees, the trees are humans good friends, they can help mankind to many things, such as clean air, and so on. So, a variety of trees, this method is very practical!

In short, our earth wanted us to take good care of yourself, to protect, want to use practical actions to help the earth, make the environment more beautiful!

先如今环保已经成为了我们必做的事，因为现在地球上的环境正受到威胁。

现在，我们知道地球已经开始变暖，寒冷地方的冰已经开始融化，变成的水使水平面越来越高，让许多沿海的国家被淹没。更多的土地沙漠化，天灾不断来袭，使我们的生活不再那么无忧无虑。

首先，我们必须从身边做起。

大片森林被不断砍伐，汽车尾气不断排放……这些首先就会直接影响到我们的生活，因为这些让我们“不敢呼吸”。所以，这些问题最好的解决方法就是少开车，多骑自行车，而且，骑自行车也很有益身体健康!。可虽然一直这样说，而且说了也不只一次，可为什么还是有那么多的车在路上呢?所以，这个方法实在，有点不实用。

最简单的就是种树了，树是人类的好朋友，他们能帮助人类许多事，比如净化空气啦，等等。所以，多种树，这个方法很实用!

总而言之，我们的地球要我们自己去爱护，去保护，要用实际行动来帮助地球，让环境更美好!

There is only one earth. He is the cradle of life, is the homeland of all mankind. However, environmental pollution and ecological destruction of normal life has been on the social and economic development and peoples constitute a real threat. Care for the environment, advocate of civilization, is the humans moral responsibility.

我们渴望干净的地球，渴望健康的地球，渴望环保的家园，渴望绿色，健康，卫生的社区……让我们用爱心去关注环境的变化，用热情去传播环保的观念，用行动肩负起环保的重任。从我做起，从现在做起，从身边的点滴小事做起，把环保承诺变为实际行动。

We desire to clean the earth, to earth for environmental health, home, eager to green, health, the health of the community...... Let us love to pay close attention to changes in the environment, with enthusiasm to spread the idea of environmental protection, with action to shoulder the responsibility of environmental protection. Begin from me, start from now, start from the side of the little things, the environmental commitments into actions.

记住，保护地球，就是保护我们自己。

Remember, the protection of the earth, is to protect ourselves.

地球，被人们称为人类美丽而又慈祥的“母亲”。这个比喻，我觉得特别亲切。“它像一个晶莹的球体，上面相互交错着蓝色和白色的纹痕，周围裹着一层薄薄的水蓝色“纱衣”。当我从《只有一个地球》这篇课文中读到这句话时，我更确定了地球的美丽壮观!而且它赋予了人类生命，为人类提供了生活所需的自然资源，所以它更像是人类的母亲，一位慈祥的母亲。

但是，在茫茫宇宙中，我们的地球母亲是那样的渺小，它只是个半径只有六千三百多千米的的星球。它所拥有的自然资源也是有限的，这些矿物资源也是经过了几百万年，甚至几亿年的地质变化才形成的。而人类就像是一个贪婪的孩子，肆无忌惮地开采资源和破坏我们赖以生存的环境，长此下去，资源没有了再生功能，那么我们拿什么生存?你也许会认为，我们可以迁移到另外的星球上去生活。你错了，科学家已经证实，没有另外任何一个星球适合我们人类居住。想到这里，我感到忧心忡忡!

一直以来，我们总以“地大物博”自居，可是，我们地是大，物真得博了吗?当人类对森林乱砍滥伐的时候，有没有想过我们的绿色正渐渐褪去;当人类滥用化学品排放污气、污水的时候，有没有想过我们的蓝色正被灰黑色的颗粒渐渐吞噬，清澈的溪水也变得混浊不堪，小鱼小虾们也没了去向。当人类破坏这些生态资源的时候，肯定不会想到自己的生命也在遭到威胁，各种各样的病症都出现了。

自私的人类真得该醒醒了，如果我们现在开始补救，应该还来得及拯救我们的地球母亲。我们要大力植树造林、严格控制工厂排污现象、保护我们的母亲河。

从我做起，从现在做起，让我们一起来保护生活的大家园，还母亲一片蓝天白云。

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.

[英语作文：经济发展与环境保护

Many animals are in danger of dying out. As is shown in the chart, we can see the number of animal species decreases faster and faster and this trend will continue. From 1980 to 2010, at least 1 million animal species have disappeared. Worse still, more and more wild animals are in great danger. It is not a piece of sensational news; it is a fact, a harsh reality. Unfortunately, we may not see these animals in the near future.

From the second picture, we can find some reasons. Why is the number of animal species declining year by year? Apparently animals have become victims of fashion industry. Animal skin has been used to make fashionable clothes and these clothes sell at a high price. So some greedy people begin to kill animals in a large quantity. This irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings.

As far as I am concerned, something must be done to stop this illegal action. We believe "no buying, no killing". First, we must make concerning laws to protect these animals in danger. Second, we must take some measures to protect animals effectively. Animals are our friends and part of our environment. Third, we should raise peoples awareness to protect animals and our environment. In this way, we can build a harmonious society and ensure a sustainable development.

Animals Need Protecting Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today.

About 170 kinds in the United States aloneare considered in danger. Why should people care? Because we need animals, and because once they are gone, there will never be any more.Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly. Luckily, some people are working to help save the animals.

Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

动物需要保护动物是自然资源,人们浪费了所有通过我们的历史。动物被杀的毛皮和羽毛,食物,运动,仅仅因为他们的方式。成千上万种动物已经从这个地球上永远地消失了。数以百计的今天也在名单之列。

在美国大约有170种aloneare认为是危险的。为什么人们会在意吗?因为我们需要动物,因为一旦他们消失了,再也不会了。动物不仅仅是漂亮或有趣。他们不仅仅是一种食物。每个动物都有其自然的平衡。毁灭一种动物会产生很多问题。例如,当农民杀死大量的鹰派,农民的玉米和谷物被老鼠和老鼠。为什么?因为鹰吃鼠类,没有鹰控制它们的数量,鼠类繁殖很快。幸运的是,有些人正在努力帮助拯救这些动物。

一些组织筹钱让人们了解这一问题。和他们试图使政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法律禁止杀害任何动物或planton名单之列。慢慢地,某些濒危动物的数目正在增长。

我在电视上曾经看到过这样一则广告：地球好像一个水龙头，每天都有很多水在流失，土地在一天天的荒漠化……直到有一天地球上在也没有水了，它在宇宙中在也不是蔚蓝色的星球了。人类再后悔也没有用了。

如果我们要环保环境，我们首先要学会节约资源。地球上的资源是有限的，迟早有用完的一天，但我们必须延迟这一天的到来。我们要从家庭做起，做个低碳家庭：少开私家车，多坐公共交通;电器不用，记得插头拔掉;倒垃圾要分类;使用节能灯……举手之劳不仅有益于家庭，更有益于保护环境，珍爱地球。

其次我们要学会保护资源。环境之所以恶化是因为人类没有好好的保护资源，还肆意的去破坏它。黄土高原水土流失严重是由于人类过度伐木引起的;温室效应是由于人类过度排放二氧化碳导致的;水污染是由于工厂违规操作所造成的……人类在做这些事的时候有没有想过，他们破坏的不仅仅是宇宙中的地球，更是人类自己的地球，没有了地球人类将如何生存?

最后我们要学会创造资源。如今科技发达，但还没有特别发达。因为人类使用的资源大部分都是污染环境的，所以我们需要研究洁净无污染的资源。这个是最有难度的也是人类最值得挑战的，也是最有价值最有意义的。如今人类烧煤炭获得能量，但烧完后还要进行尾气处理，费力又不环保，人类在大力开发一次能源，例如风能，太阳能等洁净的可再生的能源作为替代品。在此我预祝他们成功。

由此可见，保护环境是多么的重要了。一个好的环境可以促使人生长，反之，可以遏止人的生长。人类如何选择?当然，这个选择权在人类自己的手里。

法国的卢梭曾经说过：“大自然从来不欺骗我们，欺骗我们的永远是我们自己。”我们一再向大自然索取，开始它还能纵容我们，但它也是有极限的，当我们触碰了，它就向人类施行报复……这几年人类没少遇到过灾难：雪灾，旱灾。这都是人类一手造成的，天气一天天的变暖，生物的规律都被我们打破，我们还有什么颜面面对大自然呢?人类只有悔改和弥补……

地球只有一个，为了不让人类后悔，他们就必须要善待地球，为了能让人类继续生存，他们就必须要保护环境，为了能让自己有个美好的未来，他们就必须爱护自然。

灰蒙蒙的天在太阳升起的一刹那，明亮了，不那么耀眼，但却充满希望，带来温暖，而我，也醒了。

天气晴朗，景色美好，今天是世界地球日。我来到湘湖城山广场，参加萧山日报小记者亲子毅行闯关“寻宝”活动。

我和另外两位小记者组成了一个环保小队一边进行毅行闯关，一边“寻宝”，这个“宝藏”就是不讲文明的游客随地乱丢的垃圾，它影响了湘湖的风景，影响了地球的环境，我们要找到这个“宝藏”，并把它放到它该去的地方，地有烟蒂、零食包装袋和卫生纸等，我们很快就装满了一个垃圾袋。

“寻宝”的路途中还有许多亲子毅行闯关游戏，有袋鼠跳、两人三足、默契大比拼等闯关活动。我最喜欢默契大比拼，因为是妈妈比划我来猜的，我猜的很快，说明我和妈妈默契十足。

通过这次活动，我觉的我要做一个讲文明的孩子，在任何地方都不能乱丢垃圾，也不乱停自行车，学着保护地球环境。

Last week, I saw a very impressive documentary about panda. A professor

studied panda in the early 1980s went to the wild life and kept trace of wild

giant panda for many years. As a result, he found that it was human being that

made these lovely animals die out. At that time, many people believed that giant

panda became less because of the low rate of newborn babies. But it was not

true. People cut trees for making profit at that time. Panda lose homeland and

they lacked of food. Thanks to these valuable data, the government took the

policy to protect the animals. So today, the number of giant panda is

increasing. People realize the importance of protecting the environment and it

is the best way to protect wild animals, they are the indispensable part of the

nature.

Recently, it is very popular to live a low-carbon life.Living a low-carbon life is ofgreat importance to every one. First of all, it can protect the environment to a great extent. Second, it can save the limited natural resources and energy, and will leave a better world for our offspring.Third, it is a healthy lifestyle and will help mould a harmonious social atmosphere.

Therefore, how to create a low-carbon life is necessary for us to consider. To begin with, we should save the energy, such as the electricity, water and domestic gas. Second, when we go out we can walk or ride a bike instead of by car. Third, we should not use the plastic bags which are hard to break down. If so, we can live a low-carbon life and gain the happiness of it.

Environment is a basic human existence conditions, if we destroy the environment, it is ruined our survival conditions.

At present, the ecological environment is becoming more and more bad, is the greatest influence on our water resources. According to the relevant information reported: the laying of drainage system and detergent used to grow, consume the oxygen in the water, fish died, deterioration of ecosystem. Human activities can make a lot of industrial and agricultural pollutants into the water, the water is polluted. The world each year about 4200 sewage into the river, polluting the 5. 5 trillion of fresh water.

This is how the startling fact, protect the environment is everyone duty, why want to destroy?

Lies a small river near my grandmas home, on the bottom, before my sister and brother in ones childhood often swimming in the river, and their friends to play in the water, uncles and aunts are often in the river to wash clothes, wash dishes, and now, near the river built a chemical plant, the production of waste water discharge into the river, originally the bottom stream gradually turned into a black sending out the smell of the river. The adults never go to the river to wash clothes to wash the dishes, friends never go to the river to play, too!

How I miss the crystal-clear stream! I think: cherish resources, good care environment, these are GongZaiDangDai, force and art event! If we are in such polluted water, that we can use water resources will be less and less, we destroy the environment, is destroying our living conditions.

Let us join hands to jointly protect the environment, dont let water into water, protect the environment, is our common responsibility!

环境是一个人类生存最基本的条件，如果我们破坏了环境，这等于破坏了我们生存的条件。

目前，生态环境日益恶劣，对我们影响最大的就是水资源。据有关资料报道：排水系统的铺设和清洁剂的使用有增无减，消耗水中的氧，使鱼类死亡，生态系统恶化。人类的活动会使大量的工业、农业污染物排入水中，使水受到污染。全世界每年约有4200多亿的污水排入河中，污染了5。5万亿的淡水。

这是多么让人触目惊心的事实啊，保护环境是人人有责的，为什么要破坏呢?

我外婆家附近有一条小河，以前清澈见底，我的姐姐、哥哥小时候常常在小河里游泳，和他们的小伙伴们在水中嬉戏，叔叔、阿姨们也常常在这小河中洗衣服、洗菜，而如今，小河旁建造了一个化工厂，把生产的废水排放到河里，原本那清澈见底的小河渐渐变成了黑黑的散发着怪味的小河。大人们再也不去小河洗衣服洗菜了，小伙伴们也再也不去河里嬉戏!

我多么怀念那条清澈见底的小河啊!我想：珍惜资源，爱护环境，这些都是功在当代、力及千秋的大事啊!如果我们在这样污染水，那我们可以用的水资源就会越来越少，我们破坏环境，就是破坏我们生存的条件。

让我们携起手来，共同保护环境，不要让淡水变成污水，保护环境，是我们共同的责任!

随着科技的发展，人类文明又向前迈进了一大步：从以前的马车到现在的汽车;从以前的扇子到现在的空调;从以前的油灯到现在的电灯等等，它们虽然能使我们更省力，更方便，但是它们也不是十全十美，就像药品一样，它也有一定的副作用。

就拿汽车来说，它的出现使我们改变了原始以马车为主要交通工具的生活，让我们更加省力。但是它又存在着种种对环境和人体的危害。经科学研究分析发现，汽车所排放的尾气中有上百种不同化合物，当中，污染物有固体悬浮微粒、一氧化碳、铅和硫氧化合物等。一辆汽车一年排放出的有害物质比自身重量大三倍之多。在汽车大量消耗资源的同时，其排放的尾气会严重影响人类的健康。汽车尾气中的一氧化碳与血蛋白结合的速度比氧气快250倍。即使有微量的一氧化碳吸入，也可能给人造成可怕的缺氧性伤害。轻者眩晕、头痛;重者脑细胞将受到永久性的损伤。汽车对环境也有着不小的危害。尾气中的二次污染物臭氧、过氧乙酯基硝酸脂，可使植物出现坏死病斑和枯斑，乙稀可影响植物的开花结果。研究证明公路两旁的农作物减产与汽车排放的尾气明显相关。汽车所排放的尾气还严重影响了大气污染，机动车尾气污染被喻为“无形杀手”。

空调也给我们的环境带来了负担。在炎热的夏天，躺在凉爽的空调房里是一件非常惬意的事情，但是我们在享受的同时，它也在破坏着我们的环境。据调查，我国的冰山因受到温室效应，开始融化，如果在不阻止，大海的水位增加后果将不堪设想。这也是和空调息息相关的。

为了我们以后的幸福生活，让我们共同努力，从小事做起;少开私家车，尽量坐公交车;尽量少开空调等等。让我们把明天打扮的更美好!

地球的孩子有无数个，但是，地球母亲只有一个。如果，我们没了母亲，我们还怎么生存?所以，我们要爱护我们的家园。

一次次灾难的降临，地球母亲并没有把我们抛弃，可是，我们却无知地伤害了她无数次，她在痛苦的呻吟，伤心的流泪……同学们，救救咱们的家园吧!大家应该立即行动起来，从小事做起，从现在做起，从自我做起，从爱护校园环境做起，一片纸，我们捡起，一滴水，我们节约，一堆垃圾，我们打扫，我们爱一棵苗，保一蛙，种一棵草，栽一棵树，把保护环境作为自己应尽的义务，用自己的实际行动保护环境，创建绿色校园。这样，在不久的将来，再看我们的校园，我们人类的家园，必是绿的世界，花的海洋。

我们能让这个悲剧重演吗?不，绝不。我们想让我们的家园变成荒无人烟烟的草地吗?不，绝不。我们能让天和地的界限不那么清晰吗?不，绝不。

如果有一天，地球母亲真的遗弃我们了。我们该怎么办?我们还不是走向灭亡?还不如好好保护她……

总之，就是让我们好好地保护我们的家园——地球!

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。

Serious Floods

The Yangzte River is the longest river in China. And its important and helpful to us Chinese. But these days the Yangtze River is bringing us serious floods.

Many villages were destroyed by floods. The floods made hundreds of millions of people lose their homes, relatives and friends. Many children cant go to school as usual .Now the foods have drawn the attention of the whole world. People from abroad have offered their help too. In China, millions of soldiers are busy fighting against the floods. They are working very hard. Many of them have lost their lives in their attempt to save the villagers.

Though we cant help them to fight against floods, we should help them to rebuild their homeland. We can present them our pocketmoney and clothes. I believe most of the people will return to their homeland in the near future.

严重的水灾

长江是中国最长的河流。它对我们中国人十分重要。但现在长江给我们带来了严重的水灾。

许多村庄被洪水冲毁于。洪水使成千上万的人失去了家园，亲戚和朋友。许多孩子不能与平常——样去学校了。现在洪水引起了全球的注意。国外的人也给予了援助。在中国，上百万的战士忙于与洪水搏斗。他们努力工作，许多人在救村民时献出了自己的生命。

尽管我们不能帮助他们抗洪，但我们可以帮他们重建家园。我们可以捐出零花钱和衣服。我相信在不久的将来大多数人会回到家乡。

Water pollution on the impact of industrial and agricultural production of industrial and agricultural production not only need to have enough water, but also have some requirements for water quality. Otherwise, the industrial and agricultural industry will cause great losses, especially in the industrial and agricultural production process using contaminated water, the human has a great harm. First, the destruction of industrial equipment, a serious impact on product quality. Second, the chemical composition of the soil changes, fertility decreased, leading to crop reduction and serious pollution. Third, the city to increase domestic water and industrial water treatment costs.

Clean air is the necessary material basis for people to survive, an adult to breathe an average of 15 cubic meters of air a day, if people breathe heavily polluted air, no doubt harmful to health. Therefore, the study of the impact of air pollution, awareness of the value of clean air is a very complex frontier research project. And children in the growth and development stage, is the most sensitive to the outside world air pollution, the study of air pollution on children more likely to obtain valuable results. Based on this, the Chinese Academy of Engineering, China Environmental Monitoring Station Chief Engineer Wei Fusheng for the Chinese chief scientist of the Sino-US scientific and technological cooperation projects one by one air pollution on the impact of human respiratory health research, in Guangzhou, Wuhan, Lanzhou, Chongqing and other cities and suburbs The results showed that 8196 questionnaires were used to investigate the pulmonary function of children in the air, including environmental monitoring data, and about 3 million data were obtained. After statistical analysis, Air pollution has a quantitative understanding of the effects of human respiratory health (especially children). The results confirmed that the impact on human health to the fine particles of air pollution is most serious (China has 2/3 of the city exceeded), followed by sulfur dioxide pollution (1/3 of our city exceeded), the impact of nitrogen oxide pollution relative Weak. It can be said that fine particles (respirable particulate matter) is the first killer of human health. According to experts, particulate matter attached to the toxic heavy metals, acidic oxides compared with the soil enrichment hundreds of times, thousands of times, or even tens of thousands of times, and can float in the air up to several days, harmful substances with the inhalation Particles into the human lungs, and may through the alveolar into the blood, directly endanger human health.

Recently, the eight-year research results in Beijing adopted by the State Environmental Protection Administration presided over the expert appraisal. Experts believe that this research results for our understanding of the importance of clean air, improve the public and the leadership of environmental awareness is of great significance. The data of the research results provide a scientific basis for the national air environment legislation, the development and revision of air quality standards, emission standards and air pollution control policies.

同学们，你们知道吗我们的河水在以前有多么美；水清粼粼的，一阵风吹过，便荡起微波。溪边的柳枝不时伸出枝条拉动小溪的琴弦。可现在却是另一番景象；河水呈乌黑色，风吹过来还散发出一阵阵臭气。河面还飘着朔料带、坏鞋子、油桶等等。

这些都是人类一手造成的呀。让我们听听现在地球的状况吧；一、气候变化未来70年内气温升高2摄氏度以上的可能性：高危险系数：6二、端粒损来70年内由于端粒未损耗而人口锐减的可能性：低危险系数：8三、病毒未来70年内出现一种致命病毒的可能性：非常高危险系数：3四、恐怖主义未来70年内出现重大恐怖袭击的可能性：非常高危险系数：2五、核战争未来70年内爆发全球核战争的可能性：低危险系数：8六、陨星撞击未来70年内地球受到大陨星撞击的可危险系数：4能性：中等危险系数：5七、机器人反客为主未来70年内高智商机器人出现的可能性：高危险系数：8八、宇宙射线未来70年内遭遇超新星爆发的可能性：低九、超级火山未来70年出现超级火山喷发的可能性：非常高危险系数：7十、黑洞未来70年内地球被黑洞吞噬的可能性：极低

第十三，节约用水，在刷牙时，请关闭水龙头。

美丽的小溪，绿油油的草地。是我们向往的地方，大家行动起来吧，爱护家园从小事做起。

今天，我们上物理课，学到了光的色散以及光谱一课。并且，我们还认识到了比红色更“红”的红外线，以及比紫色更“紫”的紫外线。但两种光线都是看不见的。

紫外线呢，是用途广泛的一种光线，具体地说，它可以在人体内合成维生素D，促进钙的吸收，又可以用作验钞、杀菌消毒等。但是同时，它又是一种杀伤力非常强大的光线，尤其是当中对生物有害的部分(UV-B)，可是，人类又在地球上生活了差不多几百万年，这是为什么呢?

这是因为，在大气层的表面，还有一层保护着我们的东西——臭氧层。虽然，臭氧层中的臭氧含量极其微少，却具有非常强烈的紫外线吸收功能，甚至可以吸收UV-B。

所以，很庆幸，我们人类活了下来，还创造了几百万年的辉煌文化。所以，时代在不停的进步中，如今，人们有发明了电冰箱、空调等，各种各样的，这些高科技又方便的电器，让人们可以在炎炎夏日当中享受冰凉的饮料、环境等，很舒服的享受着这些电器带给他们一时的方便，可他们可曾想过，这些电器却正在慢慢地把人们推进深渊。

人们毫无节制地使用各种资源，滥用各种对大自然有害的物质，制造出令他们一时感到舒服的东西，不注意爱护环境，结果，大自然向人类报复了——1985年，英国科学家观察到南极上空出现臭氧层空洞，并证实其同氟利昂(CFCs)分解产生的氯原子有直接关系。

你们知不知道氟利昂是什么吗?它正是正在破坏地球的“罪魁祸首”!你知道它存在于哪儿吗?它就在你们家的冰箱、空调中!它是一种制冷剂，但由于大量的使用，使其产生的氯原子在南极上空大量聚集，消耗了臭氧物质，使臭氧层惨遭破坏，以致南极上空出现了臭氧空洞!

1994年，南极上空的臭氧层破坏面积已达2400万平方千米，北半球上空的臭氧层比以往任何时候都薄，欧洲和北美上空的臭氧层平均减少10%至15%，西伯利亚上空甚至减少了35%。

科学家警告说，地球上臭氧层被破坏的程度，远比一般人想象的要严重得多。如今，地球上臭氧层覆盖的面积越来越少了，这也让紫外线“有机可乘”了。

大量的紫外线从臭氧空洞进入，加速冰川融化，使海平面上升，冰封千年的古病毒可能被释放，一些岛国将面临被淹没的悲剧，陆地面积将越来越少，如果这样下去，地球将遭受灭顶之灾。

生活在地球上的同胞们，让我们来救救地球吧!难道你们忍心将人类创造出来的几百万年的文明抹杀于一个忧虑中吗?到时候，如果臭氧层没有了，人类则不能忍受紫外线的强烈刺激，从而不能在生活在地上，只能生活在地下。既便如此，到时候，皮肤每天都会被紫外线灼伤啦!难道为了自己在生活上的一点儿方便，从而要牺牲全人类，这么做值得吗?

如果不想发生“灭顶之灾”的话，现在行动还来得及!只要在不是很热的天，就尽量不要开空调啦!

你知道吗?如果全世界的人，都不用一天的空调的话，那都不知道阻止了多少氯原子的产生了!

地球终于有望得救啦!现在全球世界各地的政府都实行了控制氟利昂排放量计划啦!

各位，地球给予了我们这么丰富、优厚的物质生活，同时也需要我们去关心和爱护呀!

让我们用自己的一份力量，一起去守护地球吧!

People often say: the construction of a modern city, first of all to ensure that the city should have a good ecological environment.

Every day in the morning to go to school, he always can see the ground clean; At noon after school, I always can clearly see garbage on the ground, and trash can next to the clean, dont these people dont know garbage into the trash can? No, they know, even kindergarten children know garbage to throw into the trash, how come they dont know? They litter is completely in order to save trouble, because they are at the moment of litter didnt thought that could damage the environment, there is no thought that could bring inconvenience to the cleaners. I wonder why, these people have no morality heart? If so, I ask them to stop littering, please them to protect the city, to protect our beautiful home.

Day, the once very blue, but because of air pollution from factories, make the blue of the sky becomes cloudy; Water was very clear, but because the effluent from the factory, once the bottom stream become colorful; Forest, once very lush, but due to the deforestation of people, make once lush forest into a desolate desert...

At our side, there are many "environmental small guards", of course, there are a lot of damage to the environment behavior; Environmental protection of people we need to encourage them to adhere to the environmental protection, destroy the people we need to tell them the benefits of protecting the environment and damage the environment.

I hope that people can do it later "protect the environment, everyone duty", and the ability to truly realize the importance of protecting the environment, and make everyone around him to do this, in this way, our earth will be able to more and more beautiful, more and more prosperous!

人们常说：建设一座现代化的城市，首先要保证这座城市要有良好的生态环境。

每天早上上学时，总是可以看到地面上干干净净的;中午放学的时候，我总是能清楚地看见地上的垃圾，而旁边的垃圾桶里却干干净净的，难道这些人不知道垃圾要丢到垃圾桶里吗?不，他们知道，连幼儿园的小朋友都知道垃圾要丢到垃圾桶里，他们怎么会不知道呢?他们乱丢垃圾完全是为了省事，因为他们在乱丢垃圾的那一刹那根本就没有想过这会破坏环境，根本就没有想过这会给清洁工带来不便。我很纳闷，这些人究竟还有没有公德心?如果有，我请他们不要再乱扔垃圾，请他们一起来保护这座城市，保护我们美丽的家园。

天，曾经很蓝，可是由于工厂排放的废气，使曾经湛蓝的天空变得浑浊不堪;水，曾经很清，可是由于工厂排放的污水，使曾经清澈见底的溪水变得花花绿绿;森林，曾经很茂盛，可是由于人们的过度砍伐，使曾经郁郁葱葱的森林变成了荒无人烟的沙漠……

在我们的身边，有许许多多的“环保小卫士”，当然，也有很多破坏环境的行为;环保的人需要我们去鼓励他们坚持环保，破坏的人需要我们去告诉他们保护环境的好处以及破坏环境的弊端。

我希望，以后人们能够做到“保护环境，人人有责”，并且能够真正地意识到保护环境的重要性，并且使身边的人都做到这一点，这样，我们的地球就能够越来越美好，越来越富强!

在浩大的宇宙中，有一个球体上面蓝白交错，周围有着薄薄的浅蓝色雾气，这就是我们人类最信赖的地球。对于人类唯一生存的家园，我们人类能做些什么呢？前些天，我读了一首题为《只有一个地球》的现代诗，这首诗告诉了我许多许多

在这篇文章里，我了解到了人类所做的一些不当行为。例如在不停地索取资源的同时，还在随意破坏海洋的生态环境，让海洋里的生物都不得安宁，甚至有些生物都快灭绝了。许多树木都被人类砍伐，有些地方呈现出一副光秃秃的凄凉景象。这种破坏生态环境的行为导致了一些稀有动物物种被灭绝。如华南虎、丹顶鹤、扬子鳄等稀有动物都已寥寥无几人类快把地球几亿年的积蓄全部用光了！其最终结果必将影响到我们人类自身的生存与发展。

就拿我们可以天天看到的植物来说吧，它们为我们人类制造新鲜的空气。现在所用的煤和石油也是很久很久以前的植物衍化而来的。它们吸收着二氧化碳，吐出人类赖以生存的氧气。从某种程度上来说，植物是我们人类第三个母亲。但如此重要的植物，我们人类是怎样对待它的呢？

在我小的时候，就总是不注意那些植物。记得我读幼儿园的时候，妈妈每天接我回家。在我回家的时候总是摘一些小花小草来玩。妈妈每次提醒我不要再摘，可我总是不听。现在回想起来，我的心里非常愧疚。如果这些植物从地球上消失，我们人类就无法再在地球上生存下去了。

想到这里，我仿佛看到了一个浑身是病，丑陋无比的地球在伤心地痛哭。我们的地球是美丽可爱的，但也很容易被破坏。人类是地球最好的保护者，拯救地球，同时也是在拯救人类自己。大家快快行动起来吧！
