1996年，联合国环境部署的报告指出，南极臭氧空洞正以每年一个美国陆地面积的速度增大；空气质量严重下降，全球有1.25亿的人口生活在空气污浊下的城市中；温室气体过度释放造成全球气候变暖；地球的不行更在于人们仅污染了陆地、天空，还污染了海洋。每年人们要从船上倾倒600万吨废物大海，从船上扔下500万个塑料集装箱，漏油40万吨；目前地球上已有10%的监河流受污染，70%的引用不到安全的食用水，水源污染已成为人类健康的大敌。从森林被大面积砍伐，到水源被污染，这一切人类都被追究为罪魁祸首！这就是地球最大的不幸——人满为患！生态学家，科学家们指出：地球最多只能养活80亿人口。而到21世纪末，世界人口将达到102亿，到2500年，地球上每一平方土地就有一个人！偏偏地球又只是茫茫宇宙中人类唯一适合的孤岛。让我们用欧文的话结束全文。60年代末，美国宇航员欧文登上月球说过这样一句话：我们地球是那样的伟大而美丽，又是那样微笑和脆弱……请告诉地球上所有的人们，只有我们的地球才是温暖的，有生命的。请好好保护地球，珍惜地球。 第2篇环保作文450字

各位同学：今天我想和大家讨论环保中的一个问题——节约用水。水是大地的乳汁，我们生命的源泉。现在，我们更是离不开水，水力发电，生活用水，农业生产……这些都需要水。在过去，人们都以为水是取之不尽的，用之不竭的，但事实上不是这样的，水也是有限的。现在由于我们滥用水，污染水，水荒已经在全世界的各个角落里发生了。所以，节约用水已经成为了不得不重视的燃眉之急。许多年来，水的枯竭已经不是空头支票，而是却有其事：由于乱砍乱伐，水位下降，济南的七十二泉已有多个泉眼不喷水了，使得“泉城”济南一下子威名扫地。北京城的卢沟桥下的河水干涸已有几十年之久……几十年啦，这是个多么大的数字，难道这些事、不应该值得我们去关心，去重视吗？节约用水，利国利民，要从我们个人做起，从身边做起，从每个人做起！滴滴清水来之不易。如果每个人都浪费一滴水，整个世界就会浪费几十亿滴水，一年都能组成一条大河了！所以我们要节约用水，不污染水，这不仅为了现在，而是为了青山长绿，碧水长流！ 第3篇环保作文450字

人是自然的产物,人依赖自然而生存,这是众人皆知的道理.在生存与发展的过程中,人与自然应和谐相处.可现在,由于人口的膨胀,特别是人类的贪欲,对自然进行无节制的索取,自然已遭到严重的破坏,污染了水,减少了绿,消失了部分的生命,甚至威胁到了人类自身的生存.人与自然息息相关.人的生存就依赖于自然资源.饮用的水.取暖的煤.燃烧的油.做饭的气......无一不是直接或间接来源于自然源.地球资源再丰富,也有竭尽之时.因此,人类对自然资源的利用,特别是不可再生的资源,一定要合理开采,有效利用,切实保护自然资源,那种涸译而渔,杀鸡取卵的只顾眼前的做法,无异饮鸠止渴,最终受害的将是人类自身,人与自然资源之间,应走可持续的路子,切实保护好自然资源.人与自然之间应和谐相处,已被越来越多的人认同,接受并去实践,为什么要和谐,此中的道理很明显,人对自然超强度地索取,自然就会报复人类,这已从众多自然灾害中得到了体现.从古到今多少人为之讴歌,他们沉醉在其中而流连忘返,用他们灵性的笔,书写了经世的佳作诗篇.这些,曾让多少人为之惊叹!热爱自然.走进自然.亲近自然.书写自然吧,这将是你最美好的选择. 第4篇环保作文450字

这个暑假的一天，爸爸和妈妈带我和弟弟去大北山森林公园玩。

我们到了那儿，看见了一大片高大的森林，郁郁葱葱，遮天蔽日，林间，气候凉爽，空气清新，感觉太好了。弟弟高兴问：“爸爸，森林有什么用吗？”爸爸抚摸着弟弟的头说：“你问得好，森林好处简直太多了！高大的森林可以净化空气，是人们生活得更加健康、幸福。森林还是一座巨大的水库，它的树冠就像一把遮天雨伞，可以挡住部分雨水，不让雨水直接冲刷土地。树干上的苔藓和地上的枯枝败叶也能吸收一部分雨水，剩下来的就有土壤全部吸收，并储存起来。森林还能防风固沙、美化环境、减少噪音……”弟弟说：“啊！森林有这么多好处啊！我原来还不知道呢!”妈妈说：“你不知道的东西还多着呢！我们要多学习，多浏览，增长知识，扩大视野。”我们异口同声地说：“好！”然后，妈妈又告诉我们：“森林很重要，人类离不开它，动物也离不开它。我们要保护好森林。”

游览这个森林公园以后，我的视野开阔一点了，我想我们揭西是一个山县，森林资源丰富真是太好了！ 第5篇环保作文450字

时间总是过得这么快，一转眼就过了20年。如今已不像从前那样，一次性的塑料袋满天飞，沙漠不断往城市里蔓延，可现在，就算是有许多高楼大厦的地方，也能看见大片大片的树林。这时的我，有了一份目前最热门的工作环保发明家。20年前，或许这是一份非常冷清的工作，可是现在，公司门口每天都热火朝天的，每天就有300到400人来应聘，可每天只有100人能录取。我们的工作非常有意义，我们把一些可回收的垃圾做成树的种子、收纳盒甚至雕塑，来美化地球。另外，我们还会做一点小发明，比如说环保车、空气吸尘器、污水排离兽，这些发明都已得到人们的认可，在我们公司中最重要的发明是修补机器人，这是我们针对臭氧层空洞而发明的，这些小机器人就等于是臭氧层的医生，而他们口中喷出的气体则是药，能在5分钟内修补2平方分米的臭氧层空洞。

叮铃铃--叮铃铃我慢慢地睁开了眼睛，发现我躺在我家的地板上。啊，原来这都是梦啊！这时，我闪过了一个念头：为什么我不能把它变成现实呢？我走到阳台上，对着天空大喊：我要尽自己的一份力，让地球变成一个美丽的、被绿色包围的星球！

人与自然是相互作用的力量。

回顾历史的洪流，我们可以发现，人与自然之间存在着和谐。那时，大自然是一片可以耕种、播种和收获的净土。人尊重自然，是自然的一部分。

今天的人似乎是自然的主人，自然被撕成碎片。当我们破坏自然世界的秩序时，我们是最终的受害者，因为自然正在寻求它的复仇。森林的消失、河流的干涸、土壤的污染和气候的恶化都惩罚了贪婪的人类。我们从大自然中汲取太多，回报太少。

展望未来，当我们获得理性，当我们记起人与自然之间深刻的相互依存关系，当世界公民坚持不懈地保护自然时，自然就会成为我们的朋友，而不是我们的奴隶或仆人。当然，人们可以与自然和谐相处，有承诺，有努力，有新技术。

我们的政府将要建设一个“和谐社会”。我认为每个人都有责任努力实现这个目标。

作为学生，我们该怎么办?

首先，我们应该热爱祖国。让我们对家乡的发展充满兴趣，积极参加学校的活动。

其次，让我们用爱填满这个世界。我们应该尊敬老人、父母和老师。我们也应该互相关心，帮助那些需要帮助的人。最重要的是，我们每个人在日常生活中都必须忠诚和诚实。

最后，让我们一起努力节约能源，保护我们的自然环境，包括动物、树木、花草。

至于我自己，我会更加努力地学习，并尽我所能去做以上所有的事情。

亲爱的同学们，让我们从现在开始，不遗余力地做一点每一天，每一小时，每一分钟!

Everybody has someone in his heart that he admires very much， who may be a scientist， a writer or a musical or a movie super star。 As for the one I admire the most is my dear mother。

My mother is an honorable policewoman。 She is very busy with her job all the time。 As mom often needs to work over-time， she goes to work very early in the morning， and doesn’t come home till late at night。 Mother deeply loves her work; she treats it gingerly and conscientiously， and she is full of respected at work by her colleagues and leadership。 For always being a responsible person for the work， my mother also therefore merited many awards。

In my memory， from my childhood， my mom rarely took days off， not even for the public holidays。 When my friends went out to play with her parents on weekends， I spent my time in mom’s office。 Whenever mom had a day-off， she would be busy with preparing a delicious meal for my dad and me。 There was one time， when we were just about to start our lunch， an emergency telephone call rang up， mom hang up the call， got dressed to get ready to go out， she was even too busy to think of the meal， then rushed to her work。 Till my bedtime on that night， mom was still not home yet。 My mother works extra almost everyday， she never seems to know when she should stop it。

I admire my mom’s work spirit! I love my dearest mother!

在我的心灵词典里，有两个母亲。一个母亲是，孕育了我的生命，呵护我成长，疼我爱我的妈妈，还有一个母亲，大地是她的身躯，蓝天是她的脸颊，春风是她的呼吸，河流是她的血脉，我把她叫做：大自然母亲。

大自然母亲是美丽的，青山绿水，如诗如画;大自然母亲是慷慨的，她给予我们丰富的资源;但是，大自然母亲也是苦难的。看，一片片广袤的绿林变成了黄沙满地;听，一条条美丽的河流变成了毫无生命力的沟渠，望：一方方湛蓝的天空被烟雾遮挡，我们看不到蓝天白云，失去了漫天繁星。

“绿水青山，就是金山银山”，这句话，犹如雷一般，唤起了人们的责任。全国上下，众志成城，齐心协力绘蓝图。

在市委市政府的大力建设下，我们的家园更加清新怡人，我们的公园四季纷呈的;我们的街道瓜果飘香。作为临汾人，我欣喜，我自豪，作为蓝天小卫士，我更应多一份责任，多一份担当，我的口号是：筑梦蓝天，我是行动者。

大自然是我们共有的母亲。

为了母亲的微笑，我愿做一只飞燕。翱翔南北，为环保奔波助力。不随便踩踏草坪，不浪费文具用品，不乱丢垃圾。节约一张纸，一滴水，一度电。看到地上的垃圾主动捡起;看到长明灯、长流水主动关闭;看到浪费的不良行为，善意说服;热情传递环保能量，做环保的忠诚小卫士。

大自然是我们共有的母亲。

为了母亲的微笑，我愿做一只百灵鸟。将绿色之歌，唱给每一个人，每一个家庭，每一座城市，每一个国家，让我们手携手，肩并肩，共筑蓝天梦，人人都是行动者。

我坚信，在你我的共同努力下，每一个回家的人将会看到蓝天下的临汾，花团锦簇，华灯初上时，这颗夜明珠，将会更加璀璨夺目。

我宣誓，少年壮志不言愁，环境治理贵在行，疾风骤雨何所惧，绿水青山绘蓝图。

After a short but happy winter holiday, we come back to school today.

Its the beginning of the new term. I am happy to see all of my classmates

come back.

Because of the Spring Festival, everyone seems happy and some of them

become a little bit fatter. During the break, we talk happily to each other.

We share the happy and interesting things during the winter holiday.

Most of us stayed at home to celebrate the New Year. And some of us went to

travel with their families. In short, all of us had a happy winter holiday.

hobbies are very important to a person。 without having any hobby， life wont be as colorful as it should be。 i have a variety of hobbies， such as collecting stamps， playing musical instruments， reading， and doing sport activities。

when i am free， i will spend time on my hobbies。 when i am in a blue mood， i will also do my hobbies to cheer myself up。 hobbies can help us improve our moods。 many hobbies requires devotion。 for example， when you play a musical instrument， you have to practice over and over in order to perform good music。 after a period if you still enjoy it， gradually it will become a hobby of yours。 but， remember: a hobby is like gold under the ground; no hobby will come to you unless you dig it out yourself。

if you can treat study as one of you hobbies， learning will be more enjoyable。 i hope all of you can find your own hobbies and also have fun from them。

那天，我在家中阳台边，一边慵懒地享受着阳光，一边细细品读着一本书。突然，书中一个新颖的题目吸引了我的目光——太平洋的水，快开了。我的心猛地一揪，快速地“扫”完了这篇文章。原来，我们平时生活、工业中产生的二氧化碳，加热了地球的温度，才使得太平洋的水要“烧开”。为了地球，为了自己，为了冬天，我决定，开展低碳的“三部曲”

一个人的音符

首先，我要做到自己先低碳。

那天，我像往常一样放学回到家，又是一个人。看着空荡荡而又黑漆漆的屋子，我顺手打开了客厅的灯。唰，明亮的白光冲破黑暗。顺着灯光，我走进了我的房间。啪，我又随手打开了我房间的灯。坐在书桌前，打开台灯，我突然记起来我要低碳的。低碳的其中之一就是要节约用电！平时回家，我早已习惯顺手开灯，我可从没想过，浪费电，也不是低碳的表现！想到这里，我赶紧关掉了客厅和我房间的灯，只留一盏台灯独自在黑暗中发光。或许，这就叫做“挑灯夜战”吧。我自嘲地笑笑。自己低碳了一回。

三人旋律

个人的力量是渺小的。俗话说得好啊，人多力量大啊！我决定，让全家行动起来。

“爸、妈，手机电充好了吧？”看着躺在沙发上的两部手机，我问道。昨天早晨，我看到它们就在那里了，没想到一天过后，他们仍在原来的位置。要知道，充完电及时拔下插头，也是低碳的表现呢！“嗯，应该早就充好了，都忘掉了。”妈妈回答道。“就是，你要不说我都忘了”爸爸也接上话。看着爸爸妈妈漫不经心的表情，想想平时都是他们教训我，今天我也抓住一次当老大的机会，说道：“现在流行低碳。你们知不知道？充电器不用时拔下插头，一年可以少排放好多二氧化碳呢！”于是，我就给他们讲了讲有关这方面的知识。我看到，爸爸妈妈的表情，从一开始的漫不经心，到后来惊奇不已。最后，爸爸感慨道，：“原来我们生活中的小事，竟然可以节约这么多啊！”妈妈也说道，：“就是，以前很多东西都不注意，本以为没什么，想不到浪费了这么多东西！”我趁机说道：“那我们一起低碳吧。反正也不困难！”爸爸妈妈都欣然同意。于是我们家开始低碳。

众人的乐章

虽然全家低碳活动轰轰烈烈地展开了，可我还是不满意，我还想让的人加入低碳的行列。

经过一番商议，我们全家决定，在周末时间参加社区举办的活动。这一周是植树，那一周是捡白色垃圾，这次是宣传，那次是实践……我们一家每周都会去参加，号召大家一起加入到低碳的行列中来。我相信，只要地球上60亿人一起努力，那么温室效应一定会远离地球，太平洋的水就一定不会被“烧开”。

tell myself to stick on. Finally, I will make it and see hope. Every aim I made

completes me and makes me stronger.

I used to run about every day in previous summer vacations,this summer vacation I simply could not afford to do so.

I would soon be in the last year of my high-school education would after graduation be up against the college entrance examinations.

Though those examinations were still a year away, I had to start early to make myself well prepared by reviewing all those things I had learned at school this summer vacation was the ideal time for me to do this.

Every year billion tons of carbon dioxide is added into the air, which in part results in global warming and climate change. Now we are live in the world that is filled with pollution. As far as I am concerned, we should reduce carbon emission.

每年数十亿吨二氧化碳排放到空气中,这在一定程度上导致了全球变暖和气候变化。现在我们生活在充满污染的世界。我个人认为,我们应该减少碳排放。

First, we can adopt different ways to solve the problem if it is convenient for us, such as going to work by bus. There is no doubt that it can cut down the pollution and improve our environment. What’s more, it is cheaper, comparing with other ways. Second, there are different kinds of trees which can absorb carbon dioxide, so we also need plant more trees around us. At the same time, our government should pay attention to take action to improve our living quality.

首先, 如果对我们方便的话，我们可以采用不同的方式解决这个问题,比如乘公共汽车去上班。 无疑问,这种方式可以减少污染,改善我们的环境。更重要的是,与其他交通方式相比，它更便宜。其次，不同种类的树木可以吸收二氧化碳,所以我们还需要种植更多的树。与此同时,我们的政府应该注意采取行动来改善我们的生活质量。

It is our duty to reduce carbon emission, but it is also a long way for us to achieve it. No matter how hard the condition will be, I think if we try our best together. Maybe the problem can be solving someday, because carbon emission is a focus of the world.

减少碳排放是我们的责任,但对我们来说实现它也是一个漫长的过程。无论条件多么艰难,如果我们一起努力，也许有一天这个问题可以得以解决，因为碳排放是世界的焦点。

地球是我们共同的家，它无私地把自己宝贵的资源奉献给人类，然而人类在索取地球资源的同时，却肆无忌惮地破坏地球的生态环境。 Earth is our common home, it selflessly contributes its precious resources to humans, but when humans demand Earths resources, they dismiss the ecology of the earth unscrupulously.surroundings.

就拿我们天天能见到的水来说吧!人体内50%到60%的重量是水，没有水就没有生命。地球上的淡水资源只占地球水资源总量的3%，而这3%的淡水中，可直接饮用的只有0。5%。所以说，水是人类的宝贵资源，是生命之泉。然而，水污染在世界上相当普遍而又严重。

有一则法国寓言说：“池塘有一朵大百合花，它每天按两倍的速度生长，如果不受限制，30天内它会覆盖整个池塘，闷死水中的生物，人类直到29天才意识到这个危险——因为百合花已覆盖了半个池塘。然而，还有多少时间来挽救这个池塘呢?

不仅仅是水资源受到污染，还有人类生命和健康三大要素之一——洁净的空气同遭厄运。减少污染，净化空气，“还我蓝天红日”已成为世界各国人民的共同心愿。

随着现代科技的高速发展，我们人类发明了汽车、飞机、火车等交通工具，虽然这是我们人类在历的伟大创举，但是也给我们人类带来了巨大的危害。工厂和汽车排放出的二氧化碳是无色无味的剧毒气体，不但给人体健康造成极大的危害;还给农业生产带来巨大的损失。少量二氧化碳气体就能影响植物的生活机能，水稻扬花时受到一次熏气，产量就下降85。9%。由此看来，我们一定要保护、珍惜大气资源。
