说起保护环境,很多人都会说:“嘿!不就是环境嘛,中国地大物博,用不着保护。”这些人多么无知,其实根本不是这样的。

现在,脏水越来越多了。原本清澈见底的小河小溪变得又脏又臭,原本活蹦乱跳的小鱼也大批死去,时常看到水面上漂浮着死鱼,那是因为人们经常向这些小河小溪随意排放污水的缘故。根据专家检测,中国的水资源正在急速减少,不少水被污染,这是一个大难题。今年暑假,我乘坐盛世公主号邮轮去日本长崎玩,刚从上海港出发时,海水是黄色的而且浑浊不堪。经过两天两夜的航行,抵达了日本长崎的水域。这里的海竟然蓝的那么漂亮,让人感觉与之相比翡翠的颜色太浅,蓝宝石的颜色太深。放眼望去,蔚蓝色的大海和湛蓝色的天空连成了一条线,水天相接就像是一幅美丽的图画。马路上车辆不多,行人更是寥寥无几,街道两旁根本捡不到一个垃圾,地似乎被拖过一遍似的。接待我们的中国导游说:“之所以中国的鱼逐年减少,是因为国内渔民都用渔网捕鱼,一捕就是好几百条,而日本人是钓鱼,钓到小的还得放回去,只能钓大的不能钓小的。”这次旅游的见闻让我难以忘怀。

生活中的污染还不止水污染一种,更可怕的是大气层污染。由于汽车尾气过多和对树木进行大量砍伐,导致空气中的灰尘和尾气形成了雾霾。雾霾就像给阴沉的天空蒙上了一层灰黑的纱布,让你看不见远处的世界,空气中弥漫着一股奇怪的味道,人们出行还得带上口罩。

今年暑假,各小区都在紧急发布通告:登革热来了!这又是不好好保护环境惹的祸!这是一种花斑蚊传染病,通过蚊虫叮咬传播病毒。在夏天,花斑蚊喜欢在积水中产卵,一次可达四千颗。人们在草丛中随手乱丢瓶瓶罐罐、食品与物品的包装袋,下雨天这些垃圾容易积水。有些居民在楼道堆放杂物,在屋顶种菜养花,花盆托盘内的积水等都成了蚊虫孳生的温床。

污染环境,就是危害健康!保护环境,每个人都要行动起来!哪怕是一件微不足道的小事,也要尽自己的能力。现在,我洗碗时会把第二次洗碗的泔水用来擦饭桌、油烟机和灶台;而洗完脸的水呢,我会把它用来冲马桶;上下学接送,我让妈妈骑电动车,尽量少开车;去外面吃饭时不用一次性筷子,尽量少用餐巾纸,用自带手帕。每做一件这样的小事,我就想一想,环境是不是好了一点点呢?

保护环境,人人有责。只要每一个人共同努力,就能够还我们一个美丽的绿色家园!

In China, we can see white trash, common throw the waste battery status, protect the environment, 500 - word composition. Well look at Japan, Japans battery and white trash are through strict processing, no breach of the garbage disposal in China. I once read an article, the article mentioned in humans to Mars, lets not say whether there are suitable for human survival on Marss atmosphere, can the living. Now we have already seen, the earth has been destroyed by us so, we not only not repent, dont have to destroy another planet?

If stubbornly wait until the whole universe are we break up, we dont know to repentance? To see our mother river - the Yellow River! It used to be so spectacular, so great, is our Chinese peoples pride, between the two generations, however, you see, now whats the mother river? And a mighty momentum before? Later we if asked about Yellow River between the two generations, we how to answer, again to see the big forest into a desert, all desire become the real "Yellow River", we must continue to damage the earth? We hate Japanese dont like Japan, but please put down hatred of learning how to learn Japanese environmental protection?

Japan is the largest country in the amount of wood, but never cut down their own trees, are imported timber in foreign countries, Japan is the largest country in the world forest area accounted for the proportion. There will be a high pollution projects on foreign production. Read this, Im afraid you will scold the Japanese are trying, but its not just proves that Japan is one of the most importance to the state environmental protection?

Protect the environment, starts from me!!!!!! How many times we shout the slogan, but we have to implement? The slogan was initially we shout out, but we never have the real action, and this slogan as a basic national policy by Japan, the implementation of the little hole. This not only make the Japanese environment better, or Japan become the least amount of pollution in the air.

So Japan seems really shameless, despicable! But this is our most the place. Take a look at our central news, headlines which which where leadership is always a meeting, what was said at the meeting, but that many are just fallen on deaf ears, which can truly implement good, is all lip service, had forgot. But foreign headlines always where where what happened, for help, for the common people for the real benefits. This is the difference between China and Japan. We sell wood at a low price to foreign countries every year, and then to spend hundreds of thousands of millions of the soil and water conservation management. This is the difference between China and Japan. The frequency of the Yellow River burst its Banks over the years more and more frequent, we do not pay attention to the Yellow River is not protected and the consequences of planted?

I say this is not I...... today, I really love our country. Really hope our country can better. I described above is the living example, we see is true, to everyone. Over the years we in the development of science and technology has obtained the very good fruit, but we on environmental protection and began at least fifty years of distance in the world, do we still shouldnt have a good look at what? I said these are want you to look at our countrys environmental protection problems, lets put the protection of the environment, starts from me "to carry out the point, make our country more beautiful, more beautiful.

I am a middle school student, not how good literary grace, not how beautiful words, it can write this. But I really hope our country better, become the pride of our all Chinese people!!!!!!

It is very urgent to protect the environment,! Lets action, and work together for the motherland tomorrow.

在中国,我们可以普遍的看到白色垃圾满天飞,废电池乱扔的状况,保护环境作文500字。我们再看看日本,日本的电池和白色垃圾都是经过严密处理的,完全没有上述中国垃圾处理上的疏漏。我曾经看过一篇文章,文章中提到人类移居火星的事,咱们先不说火星上是否有适合人类生存的大气,能不能活人。现在我们已经看到了,地球已经被我们破坏成这样了,我们不仅不悔改,难道还要再破坏另一个星球吗?

是不是硬要等到整个宇宙都被我们破坏完了,我们才知道悔改?再看看我们的母亲河——黄河!它曾经是那么壮观,那么伟大,是我们炎黄祖孙的骄傲,可是,你们看看,现在的母亲河是什么样子?还有以前磅礴的气势吗?以后我们的祖孙如果问起黄河,我们又该如何作答,眼看着大片的森林变成荒漠,条条清流变成真正的“黄河”,我们还要将地球继续破坏下去吗?我们恨日本不喜欢日本,但是请先将仇恨放下学习学习日本的环境保护好么?

日本是用木材量最大的国家,但是却从不砍伐自己国家的树木,都是进口的国外的木材,日本是全世界森林面积占国土比例最大的国家。将有高污染的工程全放到国外生产。读到这里,恐怕大家免不了要骂日本人心机重,但是这不正好证明了日本是最重视国家环境保护的吗?

保护环境,从我做起!!!这句口号我们喊了多少遍了,可是我们有落实过吗?这个口号最初还是我们喊出来的,但是我们从来都没有真正的行动起来,这个口号被日本当做了基本国策,落实的没有一点漏洞。这不仅使日本的环境变好起来了,还是日本成为了大气污染最少的国家。

这么看来日本好似真的很无耻,卑鄙!但是这却是我们最该学的地方。看看我们中央新闻,头版头条总是哪个哪个领导在哪开会,会上说了些什么,但是那很多都只是耳旁风,有哪个能正真落实好的,全都是嘴上说说,过了就忘了。但是外国头版头条总是哪里哪里发生了什么,都是求帮助的,真正为老百姓谋的了福利 。这就是中日之间的差别。每年我们将木材低价卖给外国,然后又要花几十万几百万把水土治理好。这就是中日的差别。这些年来黄河决堤的频率越来越频繁,这不都是我们不注意黄河保护而种下的恶果吗?

我今天说这些并不是我崇洋媚外,我真的很爱我们的国家。真的希望我们的国家能越变越好。我上面描述的都是我们看到的鲜活的例子,都是真正的,大家有目共睹的。这些年来我们在科技发展上取得了很不错的硕果,但是在环境保护上我们却与世界上拉开了至少五十年的距离,难道我们还不该好好反思一下吗?我说这些是想让大家注视一下我们国家的环境保护问题,让我们把“环境保护,从我做起”落实到点上,让我们的国家变得更美,更漂亮。

我是个中学生,没有多么好的文采,没有多么华丽的词语,这能写到这了。但是我真的希望我们的国家变得更好,成为我们所有中国人的骄傲!!!

保护环境,刻不容缓!让我们行动起来,为了祖国的明天而一起努力。

保护环境英语作文篇1

Through observation, I found that plastic bags on peoples harm and pollution is very large。 People often use plastic bags: mother to buy food and plastic bags; to shopping malls with plastic bags; in the restaurant to eat rice is also packaged with plastic bags to take home; even I buy stationery also with plastic bags。 People do not know what they do to the environment caused by pollution, their own body caused any harm。 Such as: people often put useless plastic bags thrown into the garbage, plastic bags in the rubbish will be smelly, so that the pollution of the air。 People also throw plastic bags anywhere, a wind, plastic bags flying in the sky, the branches also see the tree is a plastic bag, and even the river there are plastic bags。 This plastic bag in addition to pollution of the air, but also polluted our water resources。

We should raise peoples awareness, tell us the neighbors and friends and family together to beautify our environment。 On the road to see the plastic bag quickly picked up, immediately took it to the garbage disposal。 We want to start from my use less plastic bags, so that my mother every day to buy food or shopping when they first take their own bags, this is not very environmentally friendly? Or can use their own holding things as far as possible by hand, no plastic bags。

As the saying goes: "to protect the environment, everyone is responsible" We have to protect the home environment out of a force。

通过观察,我发现塑料袋对人们的危害和污染非常大。人们还经常用塑料袋:妈妈买菜用塑料袋;去商场购物用塑料袋;在饭店里吃不完的饭也是用塑料袋打包带回家;连我买文具也用塑料袋。人们却不知道他们这样做对环境造成的污染,对他们自己的身体造成了什么危害。如:人们常把没用的塑料袋扔进垃圾堆,塑料袋在垃圾里会发臭,这样就污染了空气。人们还把塑料袋随地乱扔,一刮风,塑料袋在天空中漫天飞舞,树枝上也看到满树都是塑料袋,就连小河里也有塑料袋。这样塑料袋除了污染了空气,还污染了我们的水资源。

我们应该提高人们的认识,告诉我们身旁的邻居和亲朋好友一起来美化我们的环境。在路上见到塑料袋就连忙捡起来,马上把它拿到垃圾场处理掉。我们要从我做起少用塑料袋,让妈妈每天买菜或购物时都先拿上自己做的布袋,这样不是很环保吗?或者能用自己手拿的东西就尽量用手拿,不用塑料袋。

俗话说的好:“保护环境,人人有责”我们也要为保护家乡环境出一份力。

保护环境善待地球

众所周知,我们只有一个地球。地球是我们的家园。我无法想象,如果地球消失了,人类该怎样生存。

我们的生活不能离开地球,所以,请善待地球。

现在的空气不是很新鲜,天也不是那样湛蓝。这是为什么?因为有很多人乱砍滥伐,还污染河流。我们在森林里看不见小动物玩耍,也看不见小鱼在水里游泳。

如果长时间都是这个景象,世界末日就会来临。

那么,我们怎样才能保护环境呢?让我来给大家一些建议吧。

首先,我们可以植树。树木可以给予我们新鲜的空气,还可以吸收二氧化碳。

其次,我们可以坐公交去上学或上班,少开车。汽车排放的尾气会污染空气,它对我们的身体没有好处,对地球也没有好处。

这就是我的建议。

今天是世界环境日,让我们一起保护环境,善待地球吧!

全文共 899 字

亲爱的同学们:

你们好!

我是小学部的一名学生,和你们一样共同在这个美丽的校园中学习、生活。

绿树成荫的小树林,春意盎然的桃林,四季常青的苍松翠柏,如茵的草坪,再有星星点点的小花点缀其间,更有那风景秀丽的“植物园”,它们组成了风格独特、朝气蓬勃的校园。每天早上迎着朝阳,呼吸着甜润清新的空气走进课堂;傍晚,沐浴着夕阳的余辉在校园嬉戏、玩耍,对于我们这些孩童来说是一种莫大的享受。相信同为凤华学子的你们一定也深有同感。可是在我们美丽的校园中,却出现了一些很不文明的现象,这不得不引起我们的深思。

一次, 我们随着老师到植物园游玩,却在不经意中发现植物园靠边的草坪中到处都是奶袋、面包袋、一些零食的包装袋……植物园是封闭的,怎么会存在这些垃圾呢?我们的脑子中满是问号。后来经我们观察,有垃圾的地方紧靠初高中的女生公寓,垃圾是从女生公寓的窗户扔出来的。无独有偶,在一个周六的下午,老师带我们去校外郊游,又一次惊讶地发现校园外紧挨围墙的两边也是到处充斥着一些生活垃圾。毋庸质疑,这些生活垃圾是从我们校园的铁栅栏里扔出来的。还有我们学校围墙边的松树林里也存在着这些情况。另外,我发现有的学生还不爱护学校的公共设施,有的学生在打电话时还拿电话当出气筒。学校的电话已经坏了两个,可是还是没有引起大家的重视。这种种现象像一个个极不和谐的音符,遍布在学校的角落,让学校这个年轻的妈妈为之黯然失色。为了让这位校园妈妈不再伤心垂泪,在此,我提出以下建议:

一、如果在公寓吃了零食,请把一些生活垃圾扔到公寓的垃圾篓里,不要再往窗外乱扔,让植物园重新恢复她往日秀丽的容颜。

二、不要把餐厅的食物(如奶、麻花、面包之类)带到校园,不要在校园内吃零食,时时刻刻要注意维护自己的形象,要做一个文明的学生。

三、学校的公共设施不仅给大家提供了生活上的方便,而且还是学校对外交流的一个窗口,毁坏公共设施等于给自己带来不便,请大家都能爱护公共设施。

四、严格要求自己,做一个自尊、自爱、自强、自律的新世纪青少年。

学校是我家,美丽靠大家!还校园一片洁净!从自己做起,从自己身边的小事做起。弯一弯腰,动一动手,让我们一起努力,让校园的美丽在我们的手中绽放。

Everyone should protect the environment, this is the law of nature, if not protect the environment, the world will be contaminated.

To protect the environment from every bit of small start, and I have not done well. Have a New Year, we went to shun feng mountain park, riding a bicycle, we were hungry, we bought a small bag of snacks to eat, while I, eat snacks, I happy too much because it is over, so casually took me to once eat 7 packet snacks packaging thrown on the ground, and then I went in a convenience store in watching TV, while todays TV is very good-looking, half an hour later, I put the mother with all I said before, all my thoughts are indulged in the drama. After 30 minutes, I didnt think of it, but, at that time, his mother angry of say: "you this smelly wenches, didnt I tell you before to protect the environment, you forget?" I said: "Im not forget, I just from watching TV." Mother said: "some important watching TV, or picking up litter some important?" I said: "rubbish." Mother said: "you hurry up to pick up."

And then, I picked up a small pile of junk, throw in the trash, I apologized to his mother not only, I also to shun feng mountain park, sweep the floor every aunt to recognize the fault. Because, if everyone throw a piece of garbage on the ground, and then will add burden to clean the aunt. If you see a piece of garbage on the ground, then you are curved waist, and activities, do a man to protect the environment, is to clean the aunt to reduce burden...

, although it has been over the past year, I learned about it, if the world all throw a piece of garbage on the ground, the whole earth will become a waste, so each of us should protect the environment, protect the earth, the world will be more beautiful!

人人都要保护环境,这是大自然的规律,如果不保护环境,世界就会被污染。

保护环境是从一点一滴的小事做起,而我却没有做好。有一次过新年,我们去顺峰山公园游玩,骑完自行车,我们个个都饿了,我们买了一小包零食来吃,而我,吃完零食,我因为高兴过头了,所以随手就把我吃过的7包零食的包装扔在地上,然后我进去便利店里面看电视,尽管今天的电视剧很好看,过了半个小时,我把以前妈妈跟我说的话忘得一干二净,我所有的心思都沉迷在这个电视剧里面。在过了三十分钟,我才想起来,可是,这时候,妈妈生气的走过来说:“你这个臭丫头,难道我以前跟你说的要保护环境,你都忘了吗?”我说:“我不是忘了,我只是顾着看电视。”妈妈说:“看电视重要一些,还是捡垃圾重要一些?”我说:“捡垃圾。”妈妈说:“那你快点捡呀。”

然后,我捡起一小堆垃圾,扔进垃圾桶,我不但向妈妈认错了,我也向顺峰山公园的每一个扫地阿姨认了错。因为,如果每个人都扔一块垃圾在地面,那么就会给清洁阿姨增加负担。如果你看见一块垃圾在地面,那你就弯弯腰,动动手,做一个保护环境的人,那么就会给清洁阿姨减少负担……

虽然这件事已经过去一年了,但是,这件事让我学会了,如果世界上都扔一块垃圾在地面,那么整个地球就会变成一片废区,所以我们每个人都要保护环境,保护地球,世界才会更美好!

尊敬的校长:

您好!

我是一名六年级的学生,在学校的五年间,我感受到学校的美好。可我也发现学校里有不少不环保的现象,如:通知单看完后随手一扔了事;人已经走了,可水龙头的哗啦啦声一直没停下来;天气并不是很热,可还是有人开着窗户吹空调……依我看,导致这些现象的原因有很多,如坏习惯,家庭环境,依赖心理等。针对这些现象,我想向您提一些环保建议。

通知单,可以用短信、电子邮箱或飞信等电子方式来发。家里没有电脑的同学,可以让大家把通知单用作业记录的方式抄回家,这样,可以节约不少纸张,也不会出现随地乱扔通知单的现象了。

水龙头,经常出现不关的现象,有时是因为同学洗手的时候,突然响上课铃了,大家一心急,就忘了关水龙头了。学校可以把水龙头改成自动感应式的,一有人把手放进去,水龙头就开,手一离开,水龙头就自动关闭,这样就不会出现水龙头一直开着放水的浪费现象了。

空调,同学们再天气并不是很热的情况去开,是因为有时早上凉,同学们穿的衣服比较多,到了中午,温度升高,再加上大家喜欢跑,就会感觉很热,所以喜欢去开空调。学校可以在类似的季节,提醒同学们早上穿上一件可以脱的外套,到中午的时候感觉热了就脱下来,就能冷热兼顾,而不会去开空调了。

我们的校园本来是完美无瑕的,可就因为这些不环保的现象,而给美丽的校园抹上了污点,所以向你提出以上环保建议,请校长能尽快采取措施,制止校园不环保的现象发生,让我们的校园更加美好!作文

岁岁月月,朝朝暮暮;年复一年,日复一日。时光一去不复返,而地球的危机只要我们的人类不断地去努力是可以解除的。但是有许许多多的人都不知道地球的危机有那一些,如水资源的紧缺、大气资源的缺乏等等等。其实这些危机都是人为的!如:水污染危机、大气危机、森林危机、矿藏资源危机……因此,我们一定要用心去保护地球,去珍惜资源。; year after year, day after day.Time is gone, and the crisis of the earth can be lifted as long as our human beings continue to work hard.However, many people do not know the crisis of the earth, such as the shortage of water resources, the lack of atmospheric resources, and so on.In fact, these crises are artificial! For example: water pollution crisis, atmospheric crisis, forest crisis, mineral resource crisis ... Therefore, we must protect the earth with our hearts and cherish resources.

接下来让我先给你们说一说水污染危机吧!20__年1月,广西好江河水资源突发严重镉污染,该事件水中的镉含量约20吨,污染波及河段达300公里,引发当地居民饮用水安全的危机。20__年__月,云南曲靖陆良化工实业有限公司5222.38吨工业废料铬渣非法倾倒导致污染,倾倒地附近农村77头牲畜死亡。水是生命之源,万物之本。没有水我们的生命就无法生存,万物就无法生长。所以,我们一定要保护水资源,让地球上的水更清。

下面我再给你们说一说矿藏资源的危机吧。2003年对于中国的矿业企业来说,是不堪回首的一年。电荒、煤荒、油荒……从来没有像现在这样让每一个中国人感到痛彻心骨。而更多不可再生资源的全面告急,更让那些与其密切相关的人们坐立不安。去年12月,一份送往国务院的名为《矿产资源与中国经济发展》(社会版)的报告,在社会各界引起强大反响。

“该报告推翻了以往各机构关于中国近30年对石油、天然气、铁、铜等主要矿产的供需缺口预测,第一次以触目惊心的数据,彻底颠覆了‘中国地大物博’的理念。”报告以大量的事实证明,“除煤之外,我国主要的矿产资源都已告急”——中国油气资源的现有储量将不足10年消费,最终可采储量勉强可维持30年消费;到20__年,中国石油的进口量将超过5亿吨,天然气将超过1000亿立方米,两者的对外依存度分别将达70%和50%。人们啊醒醒吧!当你看到这些触目惊心的数据后,你又有何感想呢?如果你是一个有头脑的人,就一定会知道保护环境已迫在眉睫,珍惜资源要从我做起,从今天做起,从身边的小事做起。只要我们人人认真学习环保知识,努力做到珍稀资源保护地球,那么我坚信我们的地球明天一定会更美。

人们啊醒醒吧!如果再不保护地球,我们将无法生存!为了我们人类的美好生活请珍惜资源保护地球吧!

今年暑假期间爸爸妈妈带我去了承德坝上的草原大森林,参观游玩,从远到近看,就像一片绿色的海洋。

到了大森林里,我们看到了花花草草。但是草地里有各种各样的垃圾,我随手捡起一张纸,扔到了自己带的垃圾袋里。我引导着爸爸妈妈跟我一起捡垃圾,过了差不多快一个小时,才把垃圾全部捡完。

我们到了森林里看见了许多花草树木,在哪里有许多的大松树,在太阳的照射下挤出来了许许多多的松脂。有的松脂里面有昆虫,就形成了琥珀。有的人摘下琥珀说:“我看见真的琥珀了。”还有的人说:“我摸到真的琥珀了。”我们再往前走看见了只剩下树枝和树干的柳树。我们看见人们正在摘柳树的叶子,我上前去阻止说:“你们去摘柳树的叶子,柳树会疼的,如果去揪你的头发,你肯定疼的死去活来。”

有的人听了我的话,不再摘叶子了便还去保护大树,还编了一个队号叫“生态环境要保持。”我们再回到大草原上,只看见一片绿色没有一点垃圾。我们很高兴。

最后我希望大家能保护生态环境,不要随地扔垃圾,要是看见地上有垃圾要随手捡起扔到垃圾桶里,我们要一直保持好生态环境。

篇11:描写懂得保护环境的优秀

你是否曾经为了聆听众鸟的和鸣而忘我驻足?你是否曾在清澈的溪流里企图逗弄水里的小鱼而全身湿的狼狈?你是否也曾望着田间的白鹭欣羡牠自在洒脱的身影?这地球上的生物包罗万象,以广阔的海洋为基调,苍翠的森林为背景,蔚蓝的天空为渐层,无私的用它们的生命为这星球增添了缤纷的色彩。但曾几何时,原是绚丽的油彩却渐渐的变成泼墨山水,一层又一层的阴霾笼罩在我们所居住的。 Do you have forgotten to stop me in order to listen to the sound of the audience? Have you ever tried to tease the small fish in the water in the clear stream and wet the wet body?Have you ever looked at the egrets in the field and envied its free and easy figure? This creature on the planet was all -encompassing, based on the broad ocean, the lush forests as the background, the blue sky is the gradient, selflessly uses their lives as the life as the life is the life as the life is the life as the life.This planet adds colorful colors.But once a time, the gorgeous oil paint gradually became splashing ink landscapes, and the haze of layers of layers of haze was shrouded in what we lived.

始作俑者是谁?是谁扰乱了季节使侯鸟失去了方向?是谁砍伐了森林让猩猩无处可栖?是谁在流域里下毒让鱼群暴毙?是谁让被北极熊沦落到溺毙的窘境?不要再漠视眼前一切了,人类!同是这地球中繁复物种之一的你,却因为一己私利,占据了其他动物的生存空间,甚至加以迫害生态环境,使它们无家可归甚至走向灭亡。

有“生物基因库”之称的巴西亚马逊雨林,孕育了无数珍贵的物种,如:巨嘴鸟、猕猴、蟒蛇……不过,巴西人民为了种植作物,就将大片的热带雨林夷为平地,这样不仅加速臭氧层破洞,更使得钗h生物种因此灭绝,若持续下去,恐怕十年之后,“地球之肺”将不复以往,幸好。

当地政府已采取行动:每砍伐一棵树,便要栽种一棵树,希望能落实永续发展的精神,也能保护剩余的动物现今社会上伤害动物的事件也层出不穷,有的人使用捕兽夹吓唬狗儿,也有单存的驱赶,不过若是狗儿误触陷阱,可能造成他们终身残废;不肖的鱼贩为了贪图一时之快,采用“毒鱼”或是“电鱼”的方式,不但污染了河川,还有可能危害人体的健康;另外,因为地球暖化,使原本冰雪覆貌的北极冰原,迅速融化,无辜的北极熊失去了栖息地与粮食,最终将会消失在冰冷的海水中,以上几则例子,就是人类破坏生态环境的后果。

世界保护野生动物基金会就曾指出由于人类大量排放二氧化碳、砍伐森林及捕鱼,滥用大自然资源的速度已经远超过环境所能负载能力。唯有与大自然的和睦共处、尊重自然生态,并负起保护的责任,才能避免生态浩劫、减缓全球暖化、让我们携手共创美好的生态环境,为后代树立好榜样,连到永续发展的目标!

引导语:环境与人类共存,资源开发与环境保护协调。下面是小编为你带来的英语保护环境的作文,希望对你有所帮助。 保护环境初三英语作文(一)

Many people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our environment.Though the environment doesnt have a mouth to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result, the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!What we are suffering is only a small part of what the nature once suffered. If we dont take action to show respect to the environment.

Measures should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.

Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves. 保护环境初三英语作文(二)

The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially. Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment.

Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks. So we will develop and improve a new risk management system and a disaster prevention system to preserve and create the city environment where people feel easy and sound in their life. 保护环境初三英语作文(三)

Pollution has been a serious problem for a certain time around the world. There are many causes for it. Transportation is the main factor of pollution. When the waste gas from cars is released, the air is polluted. People breathing in the polluted air can develop respiratory disease. Another factor is that people throw their garbage everywhere. All kinds of garbage not only spoil the splendid environment, but also cause environmental pollution. Whats more, industrial pollution also deserves our attention. Wastewater from factories is poured into rivers and this causes water pollution. As a consequence, the greenhouse effect becomes a problem which needs our immediate caution and how to solve is urgent all over the world. At present, some measures have been taken to prevernt.

For example, people classify the garbage and some is recycled after being collected. People are also encouraged to use paper products instead of plastic products because we know that our living condition will be worse if we keep ignoring this problem. And I believe we can prevent pollution if everyone makes the efforts.

雾霾是一种雾,不要小看雾这个东西,它可以看得见,但是摸不着,所以每当雾霾这种现象来临后,天空就像被蒙上了一种看得见又摸不着的灰色的布,到了那个时候,白天云灰暗淡,一点儿阳光都无法看到,晚上甚至走路连地下的石头都看不到,就如人们近视了一样,没戴眼镜,看什么东西都模模糊糊的。

而且雾霾中含有灰尘和细菌,一但被呼吸入体内就会得病毒感冒。如果气管不好也会得支气管炎,而且还含有有害物质,而雾霾则是汽车排放的尾气是使空气受到了污染,不仅仅是一辆车排放的尾气,而是很多很多辆车的尾气集中在一起,从而形成的雾霾,如果是一辆车的。是远远不能形成的,而且城市里的汽车的数量太多,而且每一个人家都会开车,这就是形成了雾霾的主要原因。

而且不仅是汽车尾汽,施工时会有大量的沙子,泥土。而且施工的这些车子的尾气,也会产生比较严重的雾霾。拆除房子时大量的砖瓦倒地,风中含着浓重的沙子,泥土,砖瓦的气味,这些都使空气中的指数含量大大降低。

因此,我觉得保护好纯净的空气。应该从自己做起,因此我每次去学校时,总是起早些让爷爷开电瓶车去学校。电瓶车是用电的,不会产生污染。到学校也快,真是两全其美。

我觉得保护环境,应该从我做起。

今天清晨我一起床,从屋里往外看,看见屋外昏黄一片,远处的建筑物若隐若现的。我问爸爸“今天是什么天气啊?”爸爸说“今天是沙尘天。”我奇怪的问:“什么是沙尘天啊?”爸爸说:“地上的尘土飞上天就是沙尘天气。”爸爸从网上查了一下我国有十三个省都受到沙尘的影响,有些地区的人们要带着防沙面罩才能出行。我又问爸爸“他们是怎样形成的呢?”爸爸说:“都是人类乱砍树木森林,植被被破坏,植被草地被沙化,春天风大,地表的沙尘被吹上了天,就形成了沙尘天气。”

我想起来语文第七课《一个小村庄的故事》这个故事告诫我们要爱护树木,保护大自然的生态平衡,否则就会受到大自然的惩罚。我想我们的城市是不是也像故事里的那样把庄园给冲毁了呢。

老师说过一棵大树每天可以吸收大量的二氧化碳和其他的有害气体,还能抵御风沙,保护环境要从自我做起。我想:我要变成一棵树,要快快长大为人们提供氧气,抵御沙尘,假如我是一片大大的天空,我就会下很大很大的雨雪,给地球“降尘”。

总而言之,保护环境,要有实际行动,从我们自己做起,要用我们的双手保护我们这个美丽而又脆弱的地球。

同学们,你们好:

地球是我们人类赖以生存的地方,它就像母亲一样为我们提供生存资源和条件。所以大家要保护地球,珍惜自然资源、保护环境

生活中,很多同学都有浪费资源的现象:水龙头不停地流出清澈的自来水,用水的人不知去向;开着电灯、电视的房间里却长时间空无一人;笔记本随手扔进垃圾桶,却只写了几个字……这些都是在生活中存在的问题。因此,我特意提出以下建议:

1、节约用水

在使用水时,要注意以下几点:洗完手立即关上水龙头;在拖地板时不要用太多水,拖完地板的水可以用来冲厕所;

2、爱护公物

大家知道,学校的东西都是政府给的,应该爱护公物,不要破坏校园里的一草一木。如发现有同学破坏公物,应立即制止或告诉老师。

3、节约用纸

大家在用纸的时候不能浪费,没用完的纸张可以撕起来装订成草稿本。既环保又不浪费。

地球是我们的家园,是人类的摇篮。我们应该行动起来,珍惜资源、保护环境,共创美好家园!

千百年来,黄河孕育了古老而伟大的中华文明,哺育了一代又一代中华儿女。黄河是流域经济、社会发展的生命线。现在,她仍在供养着1.4亿人口、160万公顷耕地、50多座大中城市。保护母亲河,保护生态环境,是落实科学发展观,构建社会主义和谐社会的具体举措,是功在当代、利在千秋的大事。作为一个炎黄子孙我们更应该保护我们的母亲河应在全社会提倡倡导、树立绿色文明意识和可持续发展意识,社会各界的人士广泛认同和大力支持保护母亲河的行动。近年来,根据团中央及有关部委的统一部署,各省各级团组织在当地党委、政府的关心支持下,动员社会力量,扎实推进保护母亲河行动,取得了巨大的经济效益和社会效益。各省市各级环保部门要严肃处理,落实整改方案,监督恢复保护区生态环境。提出如下要求:

一是要坚决查处保护区内的违法违规行为。对于在自然保护区内开展开矿、挖沙等《自然保护区条例》明确禁止的活动和自然保护区核心区和缓冲区内的违规资源开发活动,要坚决予以取缔;对于自然保护区内和涉及自然保护区的未执行环境影响评价制度的建设项目,要依法责令停止建设。

二是要对自然保护区内造成的生态破坏,必须采取补救措施,限期治理,恢复原有生态环境。对于在自然保护区内违法进行资源开发和建设,造成自然保护区生态环境破坏的,责令立即改正违法行为,并制定生态恢复和治理方案,限期恢复原状或采取其他补救措施。

三是要严肃查处违法违纪案件,加强责任追究。对于严重违反《自然保护区条例》和有关法律、法规,在自然保护区内进行违规开发和建设,并造成自然保护区严重破坏的环境违法行为,按照中纪委、监察部加大对环境违法行为进行责任追究的要求,各级环保部门将协调监察部门,依法追究有关地方政府、自然保护区行政主管部门、自然保护区管理机构和有关责任人的行政责任。

总局将组织督查组对各地自然保护区专项执法检查工作的开展情况和重点违法案件的处理情况进行督查。并积极配合全国人大加快制定《自然保护区法》,建立自然保护区评估和升级降级制度,加强统一监管,促进自然保护区健康发展,维护国家生态安全。生态环境是人类赖以生存和发展的基本条件。保护母亲河行动以保护黄河、长江等大大小小江河流域的生态环境为主题,动员青少年,带动全社会为国家生态环境建设做贡献。近年来,保护母亲河行动组织动员3亿多人次青少年参与,面向海内外筹集资金2。5亿元人民币,建设了1103个面积达399万亩的造林工程,与30多个国家和地区开展了生态环保国际交流与合作,保护母亲河行动已经成为广大青少年和社会公众参与国家生态环境建设的重要途径,成为对广大青少年和社会公众进行生态环境意识教育的重要载体。当前,我国已进入全面建设小康社会,加快推进社会主义现代化的新的发展阶段。树立和落实科学发展观,实现人与自然的和谐、可持续发展,建设节水防污型社会,已成为我们党、政府和全体人民的共识。今年3月,温家宝总理在政府工作报告中提出了“让人民群众喝上干净的水,呼吸新鲜的空气,有更好的工作和生活环境”的环境保护和生态建设的奋斗目标,这些都为青少年生态环保事业的蓬勃发展提供了广阔的舞台。

黄河是中华民族的母亲河,曾经创造了璀璨的华夏文明党和政府历来高度重视黄河生态环境的保护和治理,取得了显着的成效。近年来,由于自然、社会等因素的影响,黄河流域生态环境建设的任务还很艰巨,保护黄河,保护母亲河,是我们义不容辞的责任。此次系列活动是围绕流域开展保护黄河生态环境的活动,山东团组织在组织实施中积极主动,多方协调,成功整合社会资源,创造性的设计活动方案,为系列活动的顺利开展打下的良好的基础。沿黄九省(区)各级团组织要高度重视,加强领导,精心照料组织,密切协作,突出特色,开展好各项活动,形成强大的声势,取得扎实的成效,真正为黄河流域的生态环境保护做些实实在在的事。

同志们,青少年朋友们,让我们积极投身保护黄河,保护生态环境的伟大事业中,为促进构建人与自然和谐相处的社会主义和谐社会做出我们应有的贡献。

保护母亲河行动是一项引导亿万青少年全方位参与生态环境保护和建设的大型公益事业,它以保护哺育中华民族的母亲河为主题,组织动员广大青少年和社会公众参与生态环境建设,六年来取得了良好的生态效益、经济效益和人才效益。去年以来,保护母亲河行动开始围绕大江大河流域的生态环境保护开展活动,先后启动实施了“共饮丹江水,保护母亲河”、“相约2008——绿色接力潮河情”、“环太湖流域青少年生态环保活动”等宣传实践活动,有效地组织动员同一个流域的青少年为同一条河,献同一份爱!

Protect environment, everyone, now, the destruction of environment has been bad, therefore, I know Protect environment.

在生活中,仍有很多人在乱砍伐树木,有一本书上写着这样一个故事:有几个人在砍树,半天就砍完一片森林,旁边有一个人,半天连一棵树都没栽下。要知道,环境对于人类来说是多么重要啊!我们破坏了环境,可是遭到报应的还是自己,仔细想想,多么不应该呀!

In life, there are still a lot of people in the indiscriminate felling of trees, a book is written in such a story: a few people in the trees, half cut down a forest, next to a person for a long time, even a tree not planted. You know, how important is for human beings! We destroy the environment, but retribution or their own, think about it, how should not ah!

虽然,政府对排污方面进行了制止,可是,还有些公司还在排污,我看到电视里的新闻:有一家公司把泥浆顺着一条蓝色的管子排放到一条小溪中来,使当地居民抱怨不已。

地球是一个美丽、富饶的星球,我们人类就居住在这个星球上。但现在地球变得不再美丽:人们为了赚钱不断地砍伐树木,人们为了方便随意乱扔垃圾……

首先,我们说说塑料袋白色污染。现在超市有很多塑料袋,都是用来装东西的。但当人们不用塑料时就会毫不在乎地把塑料袋扔掉,这样似乎很方便,但是人们有没有想过,这样随意地把塑料袋一扔会产生什么后果吗?把塑料袋随意扔到泥土上、花草里、庄稼地里,就会严重污染土地。因为塑料袋不能像树叶一样分解成肥料,所以长期将塑料袋扔在花草、庄稼所生长的泥土里,对它们不利,会影响它们的生长。

接下来,我们来谈谈砍伐树木的事情。现在人们过度砍树,一片片森林在不断地减少。要知道,树木为人类做的贡献可不少!树木可以为我们吸收废气,排放出新鲜空气,还能为我们抵挡洪水,以免发生水灾……哦,对了,还可以乘凉呢!树木为人类做出那么多贡献,因此我想问问大家人类是怎样回报树木的呢?

对于环境污染,还有很多。但是人们有没有想过采取什么措施呢?比如塑料袋,人们看见塑料袋可以把它捡起来,扔进垃圾桶里去,或者不乱扔塑料袋。还有砍树,我们可以劝身边砍树的大人让他们别再砍树了。也可以自己种植植物,为地球增添一份绿色。

我们的小区本来非常干净,可不知谁带头在草丛里扔垃圾……

有一天,我终于忍不住了,“哎,草地呀,是我们让你变的这么脏。”

于是,我从家里拿了一双筷子和一个塑料袋,就开始工作了,这里一共有两块草地,我决定一点儿一点儿的清理。这儿有一片纸,那儿有两个奶盒……草地里的各种垃圾应有尽有。

刚才那一片草地还算好,没想到这一片更糟糕,一件破衣服,一双臭鞋子,两只破鞋垫……都被我捂着鼻子夹到垃圾桶里了。清理完两片草丛我早已累的腰酸背痛,想想环卫工人们太辛苦里。

我呼吁大家,赶快拿起身边的工具,清理我们身边的垃圾吧,让我们行动起来,保护环境,人人有责!

To Whom It May Concern,

I am writing to express my opinion about the current policy on the official holidays, such as Spring Festival and Golden Week Holiday. As you might know, some believe it is a good idea to enjoy a week-long break. For one thing, it provides enough time for people to refresh their minds and thus to have better preparations for their future work. For another, it will lead to increased tourism and in turn stimulate the development of the local economy.

Truly, the past decade has witnessed many advantages of the official holidays, but we should never ignore its disadvantages. On the one hand, it may lead to heavy traffic in that a large number of tourists go on traveling during the same Period, thus, it might cause air pollution. On the other hand, some tourists, with no awareness of environmental protection, often drop litter at random so that the scenic spots are polluted and thus it demands a tremendous sum of money to eliminate the pollution.

Considering the current grim situation, it is necessary that the authorities concerned should take immediate measures to eliminate these disadvantages. Only through these efforts can we relieve the traffic pressure and at the same time raise people’s awareness of environmental protection.

Yours sincerely,

Li Ming
