保护环境的英语作文高中作文（实用20篇）

广大的青年朋友们：

你们好！

我们的地球母亲已经遭到严重的破坏，你们有想过是什么原因使我们的“地球母亲”遭到了破坏吗？其实破坏“地球母亲”的罪魁祸首就是我们……

或许，当你们听到这个答案的时候会不以为然，但是你们有没有想过你们任何的一个小行为都会破坏环境！例如：乱丢垃圾，浪费水资源……这一切的一切都会使我们的“地球母亲”遭到伤害。

当你们正坐在餐桌上吃着香喷喷的米饭时，难道你们没有想过这是“地球母亲”的功劳吗？当你们破坏自然生态平衡时，难道没有想过“地球母亲”会对我们有多失望吗？当你们在乱砍乱伐时，有没有想过“树爷爷”正在悄悄的流泪？我们在做这些事的时候，本以为会对自己有好处，可是我们在赚取利益的同时，却破坏了我们的第二个母亲——“地球母亲”。

“地球母亲”不是万能的，它也有脆弱的时候。伤害了“地球母亲”也相当于在伤害我们自己。例如：汶川大地震、洪水、河水干涸……这难道不是自然对我们的惩罚吗？难道这些自然对于我们警告还不足以让我们洗心革面吗？

有时候，人类往往会根据自己的片面认识去决定正确的事情，可是这样却往往会害了我们美丽的家园。

地球太可爱了！可是又太脆弱了，所以让我们好好的保护它吧！

谢谢大家！

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！

Traffic and Protecting Environment

交通与环保

2015年11月，全国中东部地区17省市持续雾霾，陷入大范围的重度和严重污染。造成这一现象的主要原因是工厂排出的废气和汽车尾气等。绿色低碳，保护环境，从我们身边小事做起。现请你根据以下三个方面的提示，以"Let’s Do Something to Save Our Environment"为题写一篇80词左右的短文。

内容包括：

1.重要性：只有一个地球。2.主要问题：污染、疾病、灾难。3.措施：停止污染、保护大自然。

Let’s Do Something to save Our Environment

We all live on the earth. The earth is our home. We have only one earth. We must take care of it. It gives us the best environment. If we harm it, it will be angry. And then we will have a terrible end. There are three problems in our earth, they are pollution, disaster and illness.

It’s our duty to protect our environment. So we must plant more trees, protect the flowers and the trees, save energy, reduce the pollution. We should ask our government to control the pollution from the factories.

Protecting the nature is very important. It’s our duty to keep our environment clean and tidy.

If everyone makes a contribution to protecting the environment, the earth will become much more beautiful.

[关于保护环境的英语作文示例

Generation gap refers to the misunderstanding between the old and young.

The term came into fashion after the 1980s. However, in recent years, the

phenomenon is getting more and more fierce.

How does generation gap come into being? The first reason is that the two

generations have grown up in different ages, thus they have different attitudes

toward life. Secondly, due to having little in common with each other, they are

unwilling to sit down and talk face to face. Besides, as modern life is so

stressful, both of them are so busy with their study or work that they have not

enough time to exchange their ideas.

To bridge the generation gap is not easy at all, but we can do something to

shorten it. For one thing, children should respect their parents as well as

accept their good advice. For another, parents should not only show their love

and care to the kids, but also support their good life view. As long as the old

and young can understand each other, it would be more harmonious in family and

world.

ver 70% of the Earth’s surface is water; water is obviously the most precious natural resource that exists on our planet. Without water, life on Earth would be non-existent. Water is the lifeblood of the environment, essential to the survival of all living things-plants, animals, and human. Although we recognize this fact, we disregard it by polluting our rivers, lakes, and streams. Afterward, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate, and our drinking water has become greatly affected. In order to fight against water pollution, we must understand the problems and become part of the solution; we also need to do everything possible to maintain its quality for today and the future.The government alone cannot solve the entire problem; it’s up to us when it comes to the problems we face with our water. In your home, correctly dispose dangerous household products. Keep paints, used oil, cleaning solvents, pool chemicals, and other dangerous household chemicals out of drains, sinks, and toilets because many of these products contain harmful substances. In your yard, recycle used motor oil. Avoid pouring waste oil and resist the temptation to dump wastes onto the ground.These are just a few of the many ways in which we, as human have the ability to combat water pollution. If these measures are not taken and water pollution continues, life on Earth will suffer severely.

星期三下午，我考完试回家后，和妈妈一起去公园玩。

到了公园，公园里的空气真是清新，我们沿着河岸边的小路慢慢往前走，远远就望到了几棵盛开着粉红桃花的桃树和翠绿的柳树。桃花如害羞的小姑娘羞红了脸颊，争奇斗艳；柳树舒展着秀发，迎风舞动。

我们继续往前走，看见几个小朋友在草地上蹦蹦跳跳地玩耍，把草坪破坏得乱七八糟，看到他们这样破坏草坪，我心里非常生气。

于是，我就前去驱逐他们，这一路不是看见垃圾，就是看见被折断的柳枝，我下定决心一定要好好教训他们。

我用手拽着他们，严肃地质问：“你们为什么要乱丢垃圾？为什么要折断那些柳枝呢？”他们不仅不反思，还生气了，对不服气地说：“我们这样怎么了？我们只是玩。”听到他们这样说，我更加生气了，说：“你们就能随随便便把大自然弄成这样吗？玩是玩，但你们玩的方式不对，你对得起我们的家园吗？你对得起辛勤劳作的环卫工人吗？”“你这人真多管闲事，我们玩什么，要你管呀，这是我们的事，关你屁事！”

我愤怒了，说道：“怎么不关我的事了？保护环境是靠我们大家，这里的小花小草都有生命，这里的万物都有生命，你们不能这样，保护环境，人人有责，如果破坏我们的环境，就等于破坏我们自己的家园。”听了我的这番话，他们羞愧极了，脸红着说：“对不起，我们再也不敢了，我们知道错了。”看到他们知错就改，我也欣慰了，不枉费我的一番口舌。

只有保护好环境，才能保护我们唯一的乐园。“保护环境，人人有责”，这句警示语我会铭记在心，也希望每个人都铭记在心！

保护环境的口号耳熟能详，保护环境的活动也参与过，可是发生在自己身边的环保故事很多，能这么真实而又直观的教育还是第一次。

在一个阳光明媚的早晨，我在楼道里和小伙伴们开心地玩耍时，讨厌的苍蝇满天飞，让人很反感，破坏了我们玩游戏的兴趣。于是，我和小伙伴飞快地跑回家，拿来三件“宝贝”在玩耍的地方集合。我们组成了清扫小队——“环境在我家”，便开始合作一层一层的打扫楼道卫生。

我们先用宝贝之一——“灭害灵”，把每个角落都喷洒一遍，然后用宝贝之二——“扫帚”，把死蚊虫扫到一个专放死虫子的地方。再用宝贝之三——“抹布”，把玻璃擦得亮晶晶。当电梯的门忽然打开时，保洁员爷爷看到这一幕，目瞪口呆，并夸奖我们是辛勤的好孩子。

保洁员爷爷也加入到我们的队伍中，大家一边打扫一边说说笑笑，不知不觉，我们用了一个上午的时间把整栋楼打扫得干干净净。虽然身体很累，但看到家园没有蚊虫骚扰心情很是愉悦。

从中我懂得了保护环境，人人有责。我们要从自己身边的小事做起，为维护好环境而努力。

人们常说：“爆竹声声辞旧岁，欢歌笑语迎春来。”的确，劳累了一年的中国人总爱在除夕之夜以最热闹的方式迎接新年的到来，故而燃放烟花爆竹便成为庆祝的方式之一。

“噼里啪啦……”门外传来一阵阵震耳欲聋的爆竹声，炸开后的爆竹碎片满地都是，火红火红的，伴随着它的还有那刺鼻的气味。这种浓烟和气味不只出现在我家，家家户户都充满了爆竹燃烧后释放出的浓烟，甚至整条街道、整个天空，空气非常难闻。

吃完了饭，我好奇地问爸爸：“爸爸，放这么多爆竹会不会破坏环境呢？”

“应该会吧。”爸爸回答道。

我又问：“那为什么还要放？”

爸爸：“这样热闹，图个喜庆，当然是要放的了。”我十分不理解。

清晨，我高高兴兴地跑出家门，却被扑鼻而来的浓烟呛得直咳嗽。我不由得想到：过年放烟花爆竹确实给节日添了一份喜庆，一份热闹，同时也带来了危险。

燃放烟花爆竹时产生有毒气体，会对环境造成破坏，如空气中的PM2。5浓度升高，产生大量的二氧化硫、二氧化氮等有害气体，这些气体可以在大气中聚积，造成大地越来越热，南极冰川不断融化。

还有不少人因为燃放烟花爆竹而受伤。那些顽皮的小孩在燃放爆竹的过程中，由于爆竹的威力强大，一不小心就有可能被炸伤眼睛、手指等，这可关系到孩子的未来。

门外的浓烟渐渐消散，我的心绪却并未消去。我相信，只要我们减少燃放烟花爆竹，地球就会减少一些负担，世界将会变得更加美好，金城江这座山城才会更加美丽。

Animals Need Protecting

There are more and more endangered animals at present，so how to protect them has been our task of top priority 。 Its wrong for people to hunt animals for their meat and feather，for they are our good friends。We should protect them instead of killing them。Giant pandas，which are one of the endangered animals，live in the forests and live on bamboo lealves。They can just live safely in the natural protection zones。We should stop killing animal and protect them。

Chinahas a very long and brilliant history, whose people are so friendly

and hospitable. But I am wondering why some people pay such little attention to

the environment and nature. In many places of the countryside, rivers have

become stinking sewers and brooks have disappeared. Heaps of garbage obstructs

the scarce flow of dirty water. The grounds are littered with plastic bottles

and bags. People are cutting down trees even though it is illegal. In some

towns, rubbish is hidden behind walls. Garbage cans are often of little use,

making cleaners must rush all day long and also by night to clean the

rubbish.

This lack of consideration for nature in general is extremely detrimental

to children’s education, toChina’s image, to public health, to tourism and to

the future.Chinais the common treasure of all Chinese, and we should live up to

be a member of this big family, a descendant of 5000-year-plus ancient civilized

country. I think the environment must absolutely be strictly protected by all

means. This protection should go at the same pace as the marvelous development

of the nation.

In this respect,Germanyis a rare model and leaves me a very deep

impression. After you have an exciting tour around in this country for a week or

so, it is unnecessary for you to polish your leather shoes. Personally, first of

all, the strong awareness of people’s environmental protection; then, the

advanced technology applied in the field of preserving the nature; We can learn

form others in building China into one of the most environmentally friendly

places in the world.

Throughout history man has changed his physical environment in order to

improve his way of life。 With the tools of technology he has altered many

physical features of the earth。 He has transformed woodlands and prairies into

farms and made lakes and reserviors out of rivers for irrigation purposes or

hydroelectric power。 Man has also modified the face of the earth by draining

marshes and cutting through mountains to build roads and railways。

However， mans changes to the physical environment have not always had

beneficial results。 Today， pollution of the air and water is an increasing

danger to the health of the planet。 Each day thousands of tons of gases e out of

the exhausts of motor vehicles。 Smoke from factories pollutes the air of

industrialized areas and the surrounding areas of the countryside。 The pollution

of water is equally harmful。 The whole ecological balance of the sea is being

changed and industrial wastes have already made many rivers lifeless。

Now environmental protection is more pressing than ever before。 As we know，

massive destruction of environment has brought about negative effects and even

poses a great threat to mans existence。 Indifference to these problems will

mean mitting suicide。 Therefore， effective measures should be taken and laws

passed to conserve environment。 Otherwise，man is certain to suffer from the

serious consequences caused by this lack of care for his living

surroundings。

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。 The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

月十二日是植树节，可是，我没有参加学校组织的植树节活动。第二天，将功补过，在自家小区里种下了花种。

那天早上，我拿了一袋鸡冠花种子和两棵芦荟，带上劳动工具和一个水瓶，来到楼下。我和哥哥找了一块地方，因为没有铲子，我们只好用螺丝刀替代。我用螺丝刀挖了两个小坑，把芦荟一棵一棵地种下，还在边上撒上一圈鸡冠花种子。然后，浇上一壶水就大功告成了。

在回家的路上，我想，如果我们每个人都爱护身边的植物，保护身边的动物，植树种花，那么，我们的`家园就会越变越美丽，就会到处郁郁葱葱，生机勃勃。

一边想着，一边在我的眼前仿佛出现了这样一幅画面：花儿向我点着头哈腰，好像在向我们问好；大树抖抖手臂，可口美味的果子落了下来，好像是送给我们的礼物；小草从地里探出脑袋，好像在和我们做迷藏呢……真是一个美不胜收的家园啊！

早晨，爸爸带我去了西溪湿地参加了五水共治活动。

五水共治是治污水、防洪水、排涝水、保供水、抓节水这五项。是平安浙江建设的题中的意思，也是一举多得的举措，既优化环境还惠民生。浙江“缺少水”主要是污染造成的质性缺水。“江南水乡没水喝”，就是因为太依赖资源环境消耗的粗放增长模式。

西溪国家公园湿地公园环境清幽、水道纵横，我们在这里宣传“五水共治、保护生态环境、你我共行”。

活动开始了，老师安排三人一小组，“认养”一块绿地，做“荒岛求生”的游戏，我们在绿地上发现了一处小山洞，我们爬进去，里面虽然有点黑，但可以清楚地看到洞壁上有许许多多的小生物、错综复杂的树根，小生物们可以在里面挖一处自己的窝遮风挡雨。树根上的一些小昆虫，还在悠闲地爬着，在如此生态的环境下快快乐乐的生活着，小生物、昆虫、树木、清澈地溪水，这是一个多么和谐的世界！

我们不能乱扔垃圾，比如塑料制品是不可被分解的，它会在土壤里很多年很多年，就会影响到小生物等的生存，它们就没地方去了，多可怜呀！我们要关注有些企业偷排污水，不能让清澈地溪水变得黑黑的臭臭的！

我们一定要从身边小事做起，提倡“五水共治、保护环境、保护大自然”！

我们此刻的环境太差了：垃圾到处都这样，人们随地吐痰，随地大小便。在我们周围，空气不清新了，水变的不清澈了，沙尘暴越来越多了。

有一天，走在大街上看见形形色色的人，他们一个个戴着口罩，包着脑蛋行色匆匆，从他们的眼光中看出了对环境的无奈。他们为什么都这样这样的打扮呢？因为这都这样可怕的沙尘暴使人们生活在层层包裹之中。沙尘暴来袭这样令人可怕的，大风夹杂着尘土和沙砾肆无忌惮的刮风向人们生存的土地，哪怕这样小小的缝隙也不放过，沙尘刮向农田尘土附着在刚出生的小苗上能够导致农作物不能够进行正常的光合作用，最终导致农作物因营养不良使产量下降，沙尘也这样一些疾病的“传播者”尘土吸入人们的口腔中会造成许多呼吸道疾下方这样一个真实的例子。

黄河流域自古这样我们中华民族的摇篮，也这样世界古代礼貌的发扬地之一。黄河，作为中华民族的摇篮和母亲河，不仅仅传承着几千年的历史礼貌，而且也养育着祖国8。1%的人口。然而，目前黄河流域的生态危机正在日益加剧，并且面临着土地荒漠化，水资源短缺，水土流失面积增大，水污染严重，断流加剧，生存环境恶化等诸多问题交织的严峻形势，给我们发出了严重的警示。

仅仅这样一个例子，就这样这样的令人可怕，这一切都这样因为人类贪梦的向大自然过度的索取造成的，如果人类继续这样执迷不悟下去，那么，我们赖以生存的环境将一去不复返，到那个时候，这个世界除了钢筋混凝土将再也看不到一丝绿色。

所以，要让环境变好，就要从小事做起，植树造林、持续水土、防止污染、倡导和树立绿色礼貌意识，为国家的生态环境建设做自我的一点贡献，这样我们每个公民意不容辞的职责。

我相信，在不久的将来，地球会变的十分美丽，到处这样参天大树，绿油油的草地和芳香的鲜花。气候温暖、湿润、空气清新。小鱼儿在清澈的河水里自由自在的游着，小鸟在枝头唱着欢乐的歌，无颜六色的蝴蝶在花丛中飞来飞去。

我认为完美的东西人人都很向往，所以我对地球的未来充满期望，让我们携手共同创造绿色、环保、和谐的人类大家园。

当人类诞生的时候，就想与大自然和谐地生活，一起欢乐的生活。随着人类的逐步进化，人们的生活逐渐地进入了工业化生活，什么和谐生态早已忘却了。说要保护好野生动物，却严重污染了环境……说好的呢？却已忘却。醒醒吧！人类啊！

那光秃秃的山，从现在开始植树；那餐桌上的野味，从现在开始禁止食用；那污染的环境，从现在起开始保护……

人口的迅猛增长，环境污染和人类对生物资源的过度利用等，导致地球上动植物的自然栖息地被大量破坏，大量物种的生存受到严重威胁。我国的近在眼3万种高等植物中，至少有3000种生存受到威胁或濒临绝灭。为了让更多的物种生存，人类啊，醒醒吧！不要再滥砍滥伐了。一时的诱惑蒙蔽了双眼，却不知还有更大的灾难因此而逼进，赶快醒过来吧，重建绿色家园，现在还有一丝希望，不要放弃这一丝希望，种出绿色的未来，现在开始播种。再继续破坏下去，人类和动物将再也无法生存，保护森林就是在保护我们自己的生态家园。

虽人们常说，动物是人类的朋友。可人类就是这么对待自己的朋友的吗？捕捉它们，食用它们，杀害它们，又破坏了它们的家园……其实，人类真的很残忍。动物原本与人一样，无忧远虑地生活在同一片蓝天下，但后来人类因为某种利益，开始大量捕杀野生动物。许多野生动物因此绝种或濒临灭绝。动物是人类在这个生态环境中唯一的好朋友，它们和人一样，是一群可爱的生灵，人类怎么忍心杀害它们呢？人类只是被利益充昏了头，人们啊，振作吧！不要图利益而杀害自己的好朋友，行动起来，保护好小动物们！

在这个硕大的生态环境中，人类控制着这里的一切。人们的一举一动，都将影响这个生态环境中的事物。现在，这个环境在日益地恶化着。这是人类和所有生物唯一的生态环境，人类就当是在造福生灵，行动起来吧，保护环境，不要再让这个惨局恶化下去，现在补救是唯一的办法，为了生态环境而努力吧！

保护环境，共建生态文明，共享绿色未来。

“我们只有一个地球，保护环境要从自己做起。”每当我听到这熟悉的声音，我的心底仿佛就有一个声音在呼唤：“保护环境，人人有责。”

五年前我们穰东镇的环境很差。街道很窄，路面上又有很多垃圾。夏天会发出难闻的臭味，也会引来许多的苍蝇蚊子。河面上总是漂浮着一些塑料袋，瓶子，河水又黑又臭，令人不堪入目。一些工厂的废气黄烟滚滚，飘入空中，天空也经常是灰沉沉的，看不见蓝天白云。街中心的广场上坑坑洼洼，四周也没几棵树，随处都可以看见垃圾的影子。当然，也没人愿意到这儿玩。

去年，我们穰东镇为了创建文明卫生城镇，政府也做出了很大的努力。大街小巷增添了很多垃圾桶，一大早就有很多身穿桔红色工作服的清洁工在扫地。垃圾被装进垃圾车运到了垃圾中转站。每到夏天，街道上有很多禁止焚烧秸秆的标语，还有卫星监控。很多人也把摩托车换成了电动车，许多汽车也是电动的，这样空气的污染就大大地减少了。到了春天，在街道的两边和广场上环卫工人就会种上许多树木花草。这样我们这里的环境越来越好了！

现在，走在街上，看着郁郁葱葱的树木，听着清脆悦耳的鸟鸣，人们的心情无比舒畅。街中心的广场也焕然一新，引来许多人在这里游玩。

保护环境，人人有责。我要从身边的小事做起，做一个环保小卫士。

这一切是谁惹的祸？

同学们，当你沐浴着春日里和煦的阳光，享受着自然环境给予我们的恩赐时，你可曾想过，人类同样在向大自然索取并不应得的东西… …

1998年，流经中国大地的长江、嫩江、松花江等大江大河，隐去往日温柔美丽的笑靥，露出了凶猛可怖的狰狞。肆虐的暴雨，横扫着中国的南方和北方，暴雨所到之处，江湖水涨，河沟漫溢。咆哮的江水卷起了一次又一次洪峰，吞噬了一个个村庄，一片片良田，一个个市县，一座座工厂，一所所学校。

肆虐的洪水像一只只无情的魔爪，几千万亩良田被淹，几百万人痛失家园。浩浩荡荡的江水，每天都在制造大大小小的险情。暴戾的烘魔，酿造大大小小的险情。暴戾的烘魔，酿造大大小小的悲剧…… 如果说古代科学尚未发达，大地子民们对生态的认识有一定局限，做出了只顾当前不顾长远的蠢事，那么现代人又如何呢？自1950年到1980年30年间，全世界有一半以上的森林面积被毁，其中非洲的二分之一林地变成不毛之地。绿色植被是大自然赠于人类的“生命之被”。可是，世界进入20世纪50年之后，人和动物赖以生存的绿色环境遭到破坏，绿色植被正在衰退，全球土壤流失量现以增加到每年254亿吨，沙漠化土壤正以每年5-7万平方公里的速度迅速扩展。

绿色植被被破坏，人类也无情地得到了回报。20xx年春季，我国北方发生的沙尘暴给农牧业、工矿业和人民生活造成的巨大危害，至今想来仍然心有余悸……

所有的一切引起我们的反思，是谁惹的祸？所有的一切无不在提醒着我们：防止水土流失，环境保护迫在眉睫！

“一万年太久，只争朝夕”，失去的已经失去了，再怎么忏悔，再怎么怀念都是无济于事的。就让我们把握现在，手牵手，肩并肩，深深知道“砍一棵树只需三分钟，育一棵树却要三十年”、“人类只有一个地球”的简单道理。“滴水成川，积土成山”从我做起，从小事做起，从大处着眼，以星火燎原之势轰轰烈烈地将环境保护进行到底，共同呵护我们的绿色家园。

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.

广大村民朋友们；

我镇各村的街道都已放置垃圾桶，街道也有专人清扫，我们的街道会越来越干净，我们的生活环境会越来越美好。为共同创造洁净、优美的生活环境，在此，我们倡议：

一、树立“保护环境从我做起、从点滴做起”的理念，养成正确投放垃圾的良好行为习惯。

二、村民朋友相互宣传、相互监督，对乱扔垃圾行为积极劝导，营造全体村民共同维护美好生活环境的良好氛围。

三、保洁员是捍卫环境的天使，我们要尊重保洁员的辛勤劳动成果，自觉做到生活垃圾投入垃圾桶。

四、不乱扔垃圾，具体做到：不向垃圾桶里投放明火和未燃烧完的灰烬；不向垃圾桶里倾倒污水；不向垃圾桶里倾倒建筑类垃圾、工业垃圾以及农业废物。

洁净环境靠你、靠我、靠大家！让我们立即行动起来，从我做起，从点滴做起，共同维护我们美好的生活环境，为共同打造洁净宜居、舒适优美的居住环境尽出自己的一份力！
