保护地球英语作文20句（热门20篇）

Nowadays, there are more and more students becoming short-sighted. Some students get short-sightedness when they are little. There are fifteen students wearing glasses in my class. Being short-sighted is common among students, even in primary school. That is too serious. Therefore, we should protect our eyes carefully. When we are reading and writing, we should keep a standard posture. Besides, we should not watch TV or play computer for too long. They are bad for our eyes. And, we should do eyes exercises regularly. A good rest is also important to our eyes. In all, eyes are the windows of our mind. We should keep it healthy.

Water is very important for living things. Without water there can be no life on earth.

As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. Whats more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So its high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.

With fresh water, the world will be prosperous.

I went to the gate of the primary school in shangjia city, and I was like walking into my other home, where I studied, lived, grew up, and my school was my home.

Lush trees, clean corridors, white walls. However, there are a few students on our campus who break the beautiful environment at will. The campus stairs and the various food packaging bags in the hallway, the various drink bottles of the flowers, the prunes in the classroom, the melon seed shells... The environment that makes us beautiful is destroyed, and it feels like a blank sheet of white paper. Taking care of the campus environment is the duty and responsibility of each of us.

To correct bad behavior, we cant just rely on our teachers and consciousness. Use concrete actions to protect and protect our campus environment. Start by myself, start by yourself, start every day, protect the campus environment.

从前有个地球，地球的生命已经快没了，人类还开着汽车。

有一个叫王明的小朋友，他很懂事，老是想着帮助别人。他觉得开汽车不好，就骑自行车，他用了好大的劲才骑到广场上，广场旁边的车子都开来开去，他发现有一辆汽车撞到了一个小朋友，小朋友非常疼，他说“叔叔你为什么要开车？骑自行车刹车快不是也很好吗？”那个叔叔说“骑自行车费劲，如果骑自行车我都要累死了。”王明说“为什么不要锻炼身体？不锻炼，身体就不灵活了。”那个叔叔觉得王明说得有道理，他就不开车了。

后来，慢慢发展下去，汽车越来越少了，车子的尾气也少了。现在自行车发展到有自动的，而且也不冒烟，也不用加油，踩一下可以开一个半小时，后来，世界各地都这样了。我说的这个故事是让大家少开车，多走路或者骑自行车。我们一起来保护环境、保护地球、保护我们的家园。

一天，我在校园走了一圈，发现校园里的垃圾还真不少，塑料袋，碎纸，小零食包装纸……这些引起了我的反思。 我们天天都是生活在大自然中。生活在这美好的一切当中。地球妈妈慷慨的为我们提供各种无限而又有限的资源，让我们“丰衣足食”，而人类不但不知足，反而还破坏地球母亲。随着时代的变化，人们的要求也越来越高，他们把一棵棵大树砍下做成木船、一次性筷子等一切对人类有利的东西，而这些在人类的眼里总是一闪而过，对于大自然是多么大的破坏。 虽然，现在人们处处在宣传环保，呼吁绿色，但这样仍然没有阻止破坏者的脚步，一棵棵大树仍在倒下，沙漠的面积仍在扩大。

现在，由于人类大量地砍伐树木，所以现在荒漠正吞噬着大自然，吞噬着整个地球，人们啊！难道你们就心甘情愿地看着大片的绿的被破坏？这种塑料很难腐烂，被称之为“白色污染”，用过的废弃物十分难以处理。如果埋掉，会破坏土壤结构；烧掉它，能生产出氟化物，氢化物等有毒或剧毒气体，危害人畜。真没想到，一个小小的塑料袋竟然有这么大的危害。 人们还没有意识到自己所播种的灾难时，大自然已愤然回击。海洋与大气向人类发出了警告。全球不论哪一个海域，不管它与工农业活动区有多么遥远，从北极冰岛到南极大陆，到处都不同程度的监测到有害物质，唉！我以前喜欢的海洋到哪里去了？绿如蓝，成记忆了吗？ 中国的青山绿水，正遭受到极度的摧残。工业废水的大量排放污染了我们民族的血液。森林大面积地砍伐、毁坏，使得洪水肆意猖獗，所到之处，民不聊生，眼睁睁看着家园被洪水吞噬，无不心痛。更有甚者，祖国的大动脉——黄河，已经不再是昔日养育中华民族起源的鱼肥水美之处了，却成了世界含沙量最多的河流，每年带走的泥土，不可估量。大片土地的沙漠化，也正袭击着我们居住的城市。

人们为了贪图自己的利益，在食品里放添加剂来牟取巨大的利润。由于食物中毒而导致死亡的事也时有发生。在校园里，同学们为了方便而忽略了环保的意识，口香糖随口一吐，致使校园的地面上留下了一道道黑色的“伤疤”。这数也数不清的道德问题正困扰着这条“东方的巨龙”甚至影响了它未来的发展。 人类赖以生存的地球是一个自然、社会、经济、文化等多因素构成的复合系统，地球不仅属于我们人类，相反，我们人类属于地球，我们人类和其他生物都在一个家园中，但是，近2000年来，地球上有106种哺乳动物和127种鸟类灭绝，濒临灭绝的哺乳动物就有406种，鸟类593种，爬行动物209种，鱼类242种，天呀！这是一个多么令人吃惊的数目。

从浩瀚太空，遥望地球，地球就像一个白里透蓝的玻璃球。蔚蓝的海洋，褐色的陆地，绿色的森林、草原，银线般闪闪发亮的河流，朵朵的云漂浮在上空，流出一幅幅清丽而柔和的画卷。地球的美丽而柔和的画倦，地球是美丽的星球，地球的美丽并不是仅仅在于它拥有这份罕见的蓝色，更在于它用几十年亿年的时间孕育了绿色的生命，地球迄今为止。地球是我们发现唯一拥有生命的星球，地球因生命而孤独，地球也因生命而美丽。来吧，让我们一起来保护我们这个美丽而脆弱的地球吧！因为，只有人类的心灵才能够知足这份美丽，善待地球——人类唯一的星球，我们别无选择。

虫类，数不甚数;但“钱虫”你见过吗? insects, the number is not even; but have you seen "money and insects"?

有一幅这样的画：一个人，在砍伐树木，一只啄木鸟停在他头上，一边啄他的脑袋，一边说：“这段木头里一定有虫。”是啊，的确有一条虫，一条害人害己，害地球的“钱虫”一条可以慢慢地把地球侵蚀的虫!

而这就是这幅画让我更加明白了一个道理，一个我们全人类都要知道的道理：爱护地球，保护地球。就是这么一个小小的口号，我们做到了吗?

伐一棵木看着没什么大碍，但是全世界每人砍一棵树，60亿的树木顿时消失，你们想过这个危害有多大吗?洪水，沙尘暴，土地沙漠化，山体滑坡，泥石流，等各种自然灾难，会爆发，二氧化碳会得不到净化，臭氧层会日益变薄，人类将面临灭绝的灾难。

如果我们不加节制地砍伐树木，污染土地，那么，离人类灭绝的时期就指日可待了。如果我们再肆意乱扔白色垃圾，地球将陷入空气危机，环境危机，食物危机，等一切危机。如果我们再向河流吐痰，大海吐痰，你们可以想象60亿人的痰汇成的痰海是多么“壮观”啊!

地球，原来是一个多么美丽的星球，是一个多么自然和谐的星球;可现在，被人类弄得乌烟瘴气，完全失去了以前朝气蓬勃的样子。我多么希望，大街上，不要有汽车啊，每天回家，看见汽车尾部排除的尾气让我头晕眼花，闻见那一个个刺鼻的气味让我丧失心情;我多么希望，每天上学放学都可以闻到，大自然的芬芳清香;我多么希望，当我为作业而烦心，为很多事烦心的时候，可以看到一片翠绿的景象······竭泽而渔，说的就是我们现在的伐木工人等一些人，永远只会在乎眼前，不会去想着将来所会发生的事。一旦以后发生了后果严重的事情，才知道，自己做错了事情。

我们应该大声地呼吁，大力地宣传：地球只有一个，不要让地球消失在茫茫宇宙中;地球只有一个，我们应该保护地球上的一切生物!

As we all know,the wild elephant, in South Africa, has been increasingly lessening.

Why have elephants in South Africa faced so dangerous situation?First of all,some illegal merchants catch the elephants for their tusks to make all kinds of ormaments and medicine.For the other,The area of their habitates has been increasingly decreasing.Some effective measures must be taken to solve thes problems.

As far as I am concerned,the goveronment should make serious regulations to forbid catching elephant and punish those who catch elephant badly.Besides,we should try our best to protect the habitas of those elephant,which is essential for therir existance.Moreover,more volunteers should spread the message of the importance of protecting the South Africas elephant.

If we do not take sound solution to protect,the fantastic species--=elephants in South Africa will become extinct .

I am a student from Xinhua High School in Chongqing，China. Informed that you have a vacancy for a student to serve as the spokesman for animals, I cannot resist my inner excitement,hoping to seize the opportunity to do something for animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I go and whatever I do, I usually keep in mind that animals are angels from the heaven, which bring us endless comfort and pleasure. I have been a panda lover since my childhood. Panda is so lovely that brings fun to people and they are regarded as the treasure of our country. Unfortunately，such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies.

我们常常见到广告牌上写着：“垃圾不落地，深圳更美丽”，说得多好啊!只可惜，说这些话的人们，却没能说到做到。随地乱丢垃圾，堆成“垃圾山”;汽车排出废气，整个城市被雾霾笼罩;白色垃圾到处可见，人们却无动于衷，依然说一套做一套。

因为人类的不加节制，生活中的“环境杀手”到处可见，不说远的，就说近的吧。龙华河原本是清澈见底的一条河，鱼儿在水里自由地游，河水唱着欢乐的歌。可现在呢?龙华河变成一条黑色的长龙，垃圾在它的身体内流动，鱼儿死在里面，腐烂发臭。关于这条河，有一个笑话：“如果你掉进龙华河，不是被水淹死，而是被臭死!”

放眼世界，地球上的森林正在快速的消失不见，这是为什么?砍伐机器把一棵又一棵树砍倒，换来房子、桥梁、筷子、家具可人们却没有想过，如果世界上没有森林，没有树木，泥石流将会冲下来，房子会被冲毁，家就不复存在;如果世界上没有森林，没有树木，世界上将全都是二氧化碳。没有氧气，人类如何生存?

看看我们生活的环境，白色垃圾漫天飞舞。如果我们每个人每天都制造一个白色垃圾，那我们现代的棺材就是垃圾袋，就是饭盒!如果我们继续无休止地制造垃圾，那我们的地球将会变成一片白色。不是洁白无瑕，而是毫无生机!我们的地球原本是一个美好的星球，它滋养着我们，可现在，我们却在亲手伤害它!不要再让地球妈妈哭泣了，不然，人类一定会消失在地球妈妈的怒火里。

保护环境，从我做起!从现在做起!

地球是一个有生命的星球，它总是默默无闻的为人类做贡献。可是人类却不爱护我们的母亲，不加节制的开采矿产资源，不顾后果的滥用化学品，不但是再生资源不能再生，还造成了一系列的生态灾难，给人类的生存带来了严重的威胁。

的确，我们这个地球太可爱了，可是也太容易破碎了!温室效应、沙尘暴频发、荒漠化严重、酸雨，这些都是谁造成的?人类呀，快省悟吧，地球是我们的母亲，伤害地球就是伤害我们自己呀!人类伤害了母亲，使地球失去了原有的生机勃勃，这一切使天空不再拥有往日的蔚蓝，让湖水、小溪不再拥有往日的清澈，让森林不再盎然，让鸟儿不再歌唱，让鱼儿不再快活……

1998年的特大洪水，是人类滥砍滥伐树木，不加节制开垦土地的报应;近年的夏季升温，是人类破坏臭氧的恶果!

塑料品的广泛使用，的确给人们带来了不少方便，但由于人们将废旧的塑料品随意丢弃，给环境造成了严重的危害。据说，一只塑料品埋在土地里几百年都化不掉。所以，希望大家少用塑料品，为地球母亲做出一点小小的贡献。

我们只有一个地球，这儿是人类赖以生存的家园，如果破坏了它，我们别无去处。因此，我们一定要竭尽全力去保护地球，建设地球、美化地球。让我们人类的唯一的家园――地球变得更加美丽可爱、生机勃勃，成为我们的永世乐土!

In particular, is the giant whale mass stranding of whales is not uncommon, even in the same group of whales stranded in a few days in a row, but because it has always been hard to understand. According to the scientists speculate, as the whale to have a strong group of marine animals, and the scope of activities near the coast, so there are two possibilities: First, the leading whale sick, toward the beach, the other whales also customary to follow the whale to the Forward setting; Second, the whales chasing prey into the bank. When one or a few stranded whales, other whales will follow suit or to try to rescue, resulting in a large number of whales stranded at the same time on the same piece of the beach.

地球是一个晶莹透亮的球体，上面蓝色和白色的纹痕相互交错，周围裹着一层薄薄的水蓝色纱衣，这位人类的母亲是那样美丽壮观。在茫茫的宇宙中，地球是渺小的，而人类活动的范围更小了。地球所拥有的资源是有限的，可人类随意地破坏她，是有些资源不能再生，给人类生存带来了威胁。如今，科学家证明在以地球为中心的40万公里内没有适合人类居住的第二个星球，所以我们要精心保护地球，造福后代。这是我读了《只有一个地球》所得。有了地球，有了人类，地球流着蓝色的血。

人类不该破坏地球——这位人类的母亲。可人类却做到了，是大肆地、随意地破坏生态环境。地球只有一个，足以让人珍惜，而人类却毁坏她。

如今，地球遭到了人类的重创，现已“面目全非”，许环保主义者尽力保护地球，但一切只不过是杯水车薪。地球上资源有限的，在人为破坏下，逐年减少。如水资源，它是宝贵的，人们往往以为它是取之不尽，用之不竭，然而，它在地球上却逐年减少。在科学技术的高度发展中，生态环境却遭到肆意的破坏，环境危机日益严重，人类遭到了大自然的报复：水土流失，土地沙化。大自然为人类敲响了警钟。水是生命之源，是不可缺少的，我们要节约用水，不要让水浪费掉，不知不觉流掉、渗透掉。面对之中这可怕的一切，看过，但仍是现实。保护水资源，不要让世界上最后一滴水是眼泪!节约用水，刻不容缓，因为浪费水就是扼杀人类自己。

还记得98年的特大洪涝吗?这天灾是由人造成的。河岸边树被砍光，泥土经雨水冲刷，沉在河底，水位上升，才导致大洪水。人为的破坏，使地球变灰了，变老了，地球是我们共同的家，让我们携手保护家园。还给大自然一次新的希望。

未来也许是美好的，或许是一场噩梦，不管怎样，让我们全人类行动起来，都来保护我们的地球，保护地球的生态环境，让地球为我们的子孙后代更好地服务。

当你还在破坏环境的时候，你可曾想到我们的生存环境正在一步步的恶化？当你在美丽的校园里随手扔垃圾的时候，你可曾想过白色垃圾正分布在每一个角落。当你在浪费纸张的时候，你可曾想过大树正在逐渐消失。当你在浪费粮食时，你可曾想过地球的土地正在慢慢退化。

地球，曾经是美丽的星球，现在变得一片狼藉。听过《地球治病》这篇文章吗？地球妈妈找遍了所有的地球医生，却没有治好。这篇文章告诉我们，如果真想治好地球的病状，只有人们认识到绿化这个问题，所有的问题迎刃而解。设置植树节，并不是光种树，而是要我们认识到保护环境的重要性，多种植树木。

如果没有了树木，地球将没有生命，没有优美风景，没有可爱的一切事物。从地球上有生命开始，树木就变成人类生存的基本。正是靠着树木，人类才生存到了现在，过着快乐的生活。可越是生活条件越好，人们的保护环境意识就越浅。往河里排放污水，乱砍树木……

地球的淡水资源本来就少，如果再往里面排放污水，乱投垃圾，那淡水资源就只剩一点点了。

中国的淡水资源只占世界的二十分之一，可见淡水源在我们国家是多么的少。

一个人乱扔一点垃圾，看不出地球有什么变化，可如果全球60亿每人都扔一点的话，世界会变成细菌的王国，变成垃圾满天飞，从一个世界民族之林的强者，变成一个落后的国家。

如果想拯救的地球，从现在开始，讲究卫生，每天节约一张纸。那些商家们，可以想想，是钱重要呢？还是生命重要呢？

爱护地球，保护环境！让美丽充满世界，让清香飘满空中，让绿色在世界上永远生存！

保护地球，让家园更美！

保护环境从我做起这句话人人都会说，却不是人人都能做到的。

每天我们放学的时候，经常看到有些人在路边发放小广告，有的同学拿到广告之后，看过就随手扔了。我看到了地上的广告，马上捡起来扔进垃圾箱，并告诉他们：“不要乱扔垃圾，我们要保护环境，要尊重那些环卫叔叔、阿姨的劳动成果，他们在为濮阳的环境卫生做出了重大的贡献。”

保护环境从我做起，从身边做起，从小事做起。我们也要为濮阳的环境卫生献出自己的一份力量，努力把濮阳建设成为一个美丽干净的城市。

Now, people dont speak hygiene, make the earth became very clean.

Factory waste water into the river discharge, discharge waste water will not think about it, if people drink the water, what will happen?

Also, people cut down trees, on the lawn, people will think of these things, without the trees, how do we have the fresh air and oxygen, no grass we how green home! Besides, if sandstorm comes, without the trees blocking, what will become of our home.

Why are both street trash can, this is to remind people not to throw rubbish everywhere, put the rubbish in the garbage can. But, a lot of people love throwing garbage everywhere, this kind of behavior not only damage the image of our home, what also polluted the earth again.

I want to tell everyone: "protecting the environment is to love life!" To protect the environment, we should start from the side, starts from me, to build our homes more beautiful!

现在，人们都不讲卫生，使地球变得很不干净。

工厂里的废水向河里排，排废水的人会不会想想，如果人类喝了那些水，会怎么样?

还有，人们砍伐树木，踏入草坪，做过这些事的人会不会想想，没有了树木我们怎么有新鲜的空气和氧气，没有了小草我们怎么绿化家园啊!再说，如果沙尘暴来了，没有了树木的阻挡，我们的家园会变成什么样。

为什么街道旁都有垃圾桶，这是提醒人们不要随地乱扔垃圾，把手中的垃圾扔进垃圾桶里。但是，很多人都爱随地扔垃圾，这种行为不仅损坏我们家园的形象，还让地球再一次的被污染。

我想告诉大家：“保护环境就是爱护生命啊!”要想保护环境，就要从身边做起，从我做起，把我们家园建设得更加美丽吧!

今天在学校上课的时候，扈老师要我们放学后回家上网查资料，是关于近年来我们国家某些破坏环境的例子。做完作业后，我叫爸爸开电脑给我查资料。可是不查不知道，一查吓一跳。啊！原来我们国家的矿产资源被开采得很严重，其中最容易发生意外的是煤矿倒塌。两年前，山西省中兴煤业一个矿洞突然倒塌，导致一个工人死亡。事后，老板赔钱给死者家属，意图平息此事，最后还是被发现。

这些资料告诉我们，一些商人只顾利益，而不管一切地开采，使我们的地球母亲千疮百孔，希望大家一定要保护好地球。

Throughout the ages, the earth mother with the sweet milk fed numerous generations of descendants. The original she was decorated by the junior was very clear and moving. However, now human beings for their own interests, tortured her innocent and dark. Mankind has only one earth; and the earth is facing a severe environmental crisis. "Save the Earth" has become the strongest voice of the people of the world.

Humans are part of nature and are part of the world of life. Many lives constitute a coexistence and coexistence related to the reputation of large systems. Humans must treat nature, care for the environment, protect animals and plants, otherwise, will endanger their own survival.

Once upon a time, people have been cut off, so that the ecological balance of nature has been destroyed. Dune swallowed the vast expanse of fertile land, the flood washed away the lovely home, the natural revenge of human embarrassment dumb. Mei Shui River once said that there is no natural, there is no human, this is the world a simple truth. Blindly plunder nature, conquer nature, will only destroy the ecosystem, blame themselves, so that human beings on the verge of difficulties. This sentence is not bad, people do not give natural face, of course, naturally will not give people behind the road, 98 floods, dust storms in 2000, 08 earthquake, in fact, this is the nature of the warning issued to mankind. Environmental protection is not a new problem for us, and our government has long put forward clear governance objectives. As a real life in every ordinary people, although it is impossible to directly engage in environmental protection work, but we can start from small, start from me. We should establish environmental awareness and take practical action to implement environmental action. See the faucet in the toilet when the drip should be able to raise their hands. When the battery is used up after the collection should be collected instead of readily throw away. When shopping should consciously do not use ultra-thin plastic bags ... ... a small thing though very humble, but it shows how much we have a sense of environmental protection.

Cherish resources, protect the environment. Lets make this city more beautiful!

Remember, protect the earth is to protect yourself!

人类啊，你们破坏地球还不够吗？停手吧！地球妈妈已经被你们折腾的不成样子了，为了保护地球妈妈，我建议人类，从此时此刻做起，从小事做起，哪怕你弯下腰捡垃圾袋，都可以啊！只要不是随便乱人垃圾，和随地吐痰的人类，我们都欢迎您加入我们，保护地球妈妈没有多难，你们的乱砍伐树木，导致你们的后代将看到的是一片光秃秃的树枝的丫丫，人类啊，就此停手吧！别伤害我们的地球妈妈了，她禁受不起你们的一番折腾了，一次，我梦到地球妈妈来到我的身边了，我看地球妈妈憔悴不堪，问她原因，她说：“是那些可恨的孩子们把我弄成如此不堪，，你可不可以告诉他（她）们不要再乱砍乱伐了，停手吧！”“地球妈妈，我可是可以帮你，但是我没这个能力帮您宣传啊！我只是一个初中生，地球妈妈别灰心，他（她）们乱砍乱伐会遭到大自然的报复的，山啸、洪水、地震、火山爆发等等，地球妈妈，别操心了好吗？这样对您的身体没有好处，只有坏处。”“好，我不生气，好了时候也不早了，我要走了，

再见孩子，真心希望他（她）们能够保护此时此刻憔悴不堪的我。”说完地球妈妈不见了，我暗自想：也许此时此刻的地球母亲真的憔悴不堪了，只能呼吁人类不要再对地球母亲下手了。“啊，原来是做梦啊，但是梦中的地球母亲好憔悴啊，哎！人类啊！你们什么时候才能停手，帮助地球妈妈完成她的心愿呢！”

人类啊，请教你们的孩子从身边的小事做起，告诫他们千万不要乱砍乱伐了，地球妈妈禁不起他们的折腾了！如果此时此刻的他们还不停手，那我肯定人类以后没有安宁的日子，大自然会用它的一切帮地球妈妈报复你们的。当你们意识到时候吗，可能已经晚了，大自然天不见你们的懊悔，处处对我们进攻，我们防不胜防。最后，我还是想说：人类啊！就此停手吧！也许此时此刻停手还有挽救的余地，到那时停手没有挽救的地步了你们才甘心吗？呼吁你们的子女收手吧！我会帮你们求情，告诉地球妈妈你们所犯下的错误，今后你们会改正，让大自然别伤害你们，那还有可能有挽救的余地。

保护地球就是保护人类自己，不要因为自己的自私，而让所有的人类跟你一起受罪，不要因为你所谓的钱财而把你自己埋葬。

[保护地球800字作文

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。

最近，我看了一幅这样的漫画，漫画的主要内容是：地面上建了无数的工厂，工厂排出的废气，使地面上的花草树木都枯萎了，请保护我们的家园——地球。有两个人拿着他们的行李匆匆忙忙地跑到地下去找他们的祖宗，让他们的祖宗安排他们住在地域里，离开这个到处都是废气的地面。

这幅漫画主要是反映了现代社会上的一些人，他们为了自己的利益而乱建工厂，滥用化学物品，不节约用水、用电，使我们本来是那么可爱的家园——地球受到了严重的破坏；把一个到处都是绿树的星球变成一个建满高楼大厦，到处都是汽车，到处充满废气的星体；使本来是一个充满光明的星球变成了一个黑暗的星球；使本来是一个有着丰富资源的星球变成一个一无所有的星球。

就拿我的家乡来说吧。我小的时候，妈妈经常带我去一些树林里玩。但是，近年来，由于人们为了金钱而把树林里的树木全都砍光，去建了许多工厂。使以前空气清新的树林，顿时间，变成了空气浑浊的工业区。

啊，人类，你们真不该！其实这样做，最终的受害者还是我们人类自己。

地球母亲，请您放心，我们一定会把您变得像以前那样空气清新，决不会再让你受到破坏。

要实现这个理想，我们现在开始就要努力学习，打好基础，掌握科学知识，长大后做一个有知识的人。我们都常说：

“保护环境，人人有责。”生为新世纪的接班人——我们应该从小树立起保护好环境的信心。把我们的家园——地球建设得更美丽，使我们的地球变得处处充满生机，处处充满希望，处处充满光明，使我们的后代拥有一个美丽的家园，我想：这应该是我们每个人的心愿。

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.
