万物之灵的人类:

如今经济发达的地球,从表面上看,虽然高楼林立,环境优美,但是却有着十分巨大的隐患,地球大约每天倒下五亿棵树,你知道让地球伤痕累累的是谁吗?是人类,让可再生资源变成了不可再生资源。

你们居住的地球已伤痕累累,不堪一击了,你们听到地球母亲的哭声了吗?其实只要我们人类保护环境,不破坏一棵树就行,因此,我郑重地向你们这些号称万物之灵的人类提出建议:

1、 节约用水,减少对水的污染,随时不让水龙头哭泣,防止滴漏;

2、 到外面吃饭时不能用一次性餐具;

3、 不要乱扔果皮纸屑,不能乱吐痰;

4、 不要乱伐树木。

在一个公园里有一条干净的小路。

一个阳光明媚的大早上,在公园的小路上人很多,我看见有好多人在草地上野餐,我走了一圈发现公园的地上,有很多垃圾,我又发现草地上也好脏,我和妈妈马上跑出了公园,在公园里的人越来越少,过了一会儿,公园没人了,我伤心地说:“妈妈,公园好嗅啊!”妈妈和蔼可亲地说:“不行,公园再这样就没有人来这玩了。”“那怎么办呀?”我伤心极了!

后来妈妈去买了个东西,妈妈给我了口罩,我们把香气的东西一个个放了进去,我把每个地方都放了一个。过了一会儿,公园香啊,我拿了袋子就进去了,我和妈妈在里面。

过了一会儿,有一个人来了,她和我们一起打扫,很快就好了,又有很多人来了,我开心地笑了。

我们就该保护环境,保住环境是我最大的快乐。

以前,世界是美好的,鸟语花香,绿树红花,动物和人类幸福地生活着。随着时代的发展,工厂越来越多,把污水排到小溪里、小河里,导致水流被污染,小鱼也被污染死掉了。如果世界上还有最后一滴干净的水的话,那这最后一滴水将会是人类的眼泪。此外,工厂还随意排放废气,空气都被污染了,pm2。5也不断地增高,不仅我们人类生活在毒气中,废气排到森林,还会导致树叶全部枯萎。我们都知道,树叶可以通过光合作用来释放氧气,净化空气;如果没有了树叶,雾霾将不断扩散,到时候人类就会因为没有纯净氧气呼吸而死。因此,我呼吁从此刻开始,人人都做环境小卫士,让我们为保护环境而奋斗吧!

主席说过,“绿水青山就是金山银山,宁可要绿水青山也不要金山银山”,从现在开始,让我们从自己做起,携起手来,保护环境,保护我们的家园吧!

亲爱的家长们,市民们,同学们:

近期发现本市环境直线下降,街上随处可见塑料瓶和易拉罐,水中也漂浮着塑料瓶和一次性塑料盒。垃圾桶旁堆着如小山一般的垃圾,而垃圾桶内的垃圾却并没有填满。绿化带中的垃圾更是数不胜数,学生吃零食吃剩残渣和包装袋,把地上的小草压得不起腰。在此,我对广大市民们提出以下倡议:

1、大人们以身作则,真正做到垃圾不落地,争当好市民。不随手乱扔垃圾,把垃圾送回“家”——垃圾桶。

2、家长们要做好带头作用,主动把垃圾扔进垃圾桶。

3、学生养成垃圾分类的好习惯。

各位市民,只要我做到凡事从我做起,从小事做起,每个都不乱扔垃圾,那么,聚沙成塔,众志成城,终有一天,我们这个城市将变成一个环保、温馨、整洁的美丽城市,愿我们每个人从现在开始就行动起来。每个人都为美化环境、文明城市作出自己的贡献。

我看了一些资料,读出了许多道理。人们过的生活越来越先进了,虽然有了高科技的设备,但污染的情况越来越严重了。

许多冰川随着人类的过度的开发慢慢地融化,多少企鹅、海鸟的羽毛被污染的水弄得不能保温,不能捕食,最后冻死或饿死了,擅长游泳的北极熊竟然会被淹死,累死。动物是人类的朋友,如果他们都灭绝了,就我们人类留在地球上,全世界都污染严重,那地球就会变成一个死球了。

国外也因为人类的破坏而环境受到污染,什么布列塔尼海岸碰到礁石沉没,漏出原油22.4万吨,污染了350公里长的海岸带;在博帕尔市郊的“联合碳化杀虫剂厂”存贮45吨异氰.酸甲酯贮槽的保安阀出现毒气泄漏,1小时后毒烟蔓延着整个城市;美国东北部和加拿大东南部多个湖泊池塘漂浮死鱼,湖滨树木枯萎……

我们国内因为沉重的人口负担,所以人均资源不足,但人们还破坏着花草树木,污染着环境,让从工厂排出来的乌黑的烟跑到湛蓝的天空上去,让从物品上制造出来的垃圾随风飘。

为了我们的家园,爱护环境,保护动物吧!

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。

保护环境英语作文(一)

With the improvement of our living standard, more and more people can afford a car。 As a result, our roads are more often than not crammed with cars。 However, with more and more waste gas being discharged by the cars, the problem of air pollution bees even more serious。 So nowadays we advocate to lead a low-carbon life。

My suggestion is we should ride bikes more often instead of driving cars。By riding a bike, we can not only exercise our body but also protect our environment。 Why not have a try, my dear friends?

保护环境的英语作文(二)

As we all know, the environment around us is getting worse and worse /more and more seriously today。 Water is polluted, we have no clean water to drink。 Many trees are cutting down, some animals are getting less and less。 Some factories are pouring dirty air into the sky。 The population is increasing faster and faster, resources are getting less and less…etc。 Not only does it affect our lives and health, it also has a great affection in the future。 People’s health has been greatly affected by air, noise and water pollution。 Many people died of diseases。 In order to live a better life, something must be done to stop the pollution。 It’s our duty to protect our environment。 We shouldn’t throw away rubbish everywhere。 Trees are very helpful and important for us。 We should plant more and more trees in order to live better and more healthy in the future。

If everyone makes contribution to protecting the environment, the world will bee much more beautiful。 In a word, if everyone pays more attention to our environment, there will be less pollution and our life will be better。 “There is only one earth”, I hope everyone will protect our environment well。

保护环境的英语作文(三)

There are still many problems of environmental protection in recent years。 One of the most serious problems is the serious pollution of air, water and soil。 the polluted air does great harm to people’s health。 The polluted water causes diseases and death。 What is more, vegetation had been greatly reduced with the rapid growth of modern cities。

To protect the environment, governments of many countries have done a lot。 Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution。 Therefore, governments are playing the most important role in the environmental protection today。

In my opinion, to protect environment, the government must take even more concrete measures。 First, it should let people fully realize the importance of environmental protection through education。 Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution。 Finally, those who destroy the environment intentionally should be severely punished。 We should let them know that destroying environment means destroying mankind themselves。

保护环境的英语作文(四)

Environmental problems are as big as not for individual country or individual people to address。 In other word, we have reached the stage that environmental problems be solved for international view。 To what extent do you agree or disagree?

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。

最近,在我们生活的家园——地球上,频繁的发生自然灾害,而这些灾害的罪魁祸首就是人类,是人类不保护环境所造成的。所以,我们要保护环境。

上次,我们学校组织了“扫街活动”,这次活动主要的目的有两点,一:清理街道上的垃圾;二:呼吁大家一起保护环境。

那天,大家都是“全副武装”,有带小铲子的、笤帚的、抹布的等等,真是五花八门、样样俱全。随后我们六年级全体师生都来到了赣州小南门路。到了哪儿,大家都分工合作,有扫地的、铲广告纸的等等。我被分配到了铲广告纸的工作,于是我先拿一桶水将墙上浇湿,广告纸湿了之后很容易清理,我再用小铲子把墙上的广告纸一点一点的铲除。其他待了小铲子的同学也一起加入到我的工作里来。

街边过路的行人都夸我们是好学生,我们感到非常的自豪,这使我们更有劲了。于是我们这儿刷刷那儿铲铲,都乐此不疲。一会儿,老师走过来,表扬了我们,说我们干的非常的好,还给我们每个人发了一张小奖状。回家的时间到了,我们都依依不舍的散去,希望下次学校还能举行“扫街活动”。

进过这次扫地的经历,我知道了保护环境的重要性,也正好印证了这句话“保护环境,人人有责”,也希望有更多的群众加入到保护环境的行列中来。

可是地球人为了潘多拉星球上的资源把参天的大树砍得一根也不剩、美丽的森林变成一片焦土、动物们都无处藏身,晚上森林再也不会发出蓝色的萤光了,整个星球变得漆黑一片,人们无家可归。

地球哪?人们过度的砍伐树木,导致泥土流失,造成了沙尘暴。

人们的工厂把有毒的物质排放到水里,人们喝了对人体造成了极大的伤害,水中的生物也遭受了灭顶之灾,许多生物已经濒临灭绝了。

汽车排放的尾气、工厂排放的有害气体,对地球的大气层的伤害越来越大,导致大气层越来越薄,太阳的紫外线越来越强,气温越来越高,更为严重的是造成了江南地区大面积出现阴霾天气。

如果地球环境被人们在这样破坏下去,潘多拉星球的今天,就有可能是地球的明天,为了地球美好的明天,让我们多植树造林、减少汽车的尾气和工厂的排放,一起努力保护环境吧!

这个暑假,我参加了社区组织的保护环境活动,这次活动主要是针对一次性用具展开的。

在社区里,我们经常能看到大家拎着塑料袋,使用一次性的纸杯,在小餐馆里,大多数使用的都是一次性筷子,还有快餐盒等等。因此,社区领导针对此现象,展开了一次环保活动,由小区里居民自愿报名参与。

我们将使用一次性用品对我们人的身体和对社区的环境所产生的影响一一列举出来,然后打印出来。早上我们站在小区的不同入口,将传单分发给居民。假如他们有时间,我们会为他们一一做解答。傍晚,我们在社区的空旷处举办了一次活动,主要是让大家上去讲讲对一次性用品的认识,最后活动的领导对使用一次性用品的弊处进行总结,并告诉大家如何从自己的身边进行环保,呼吁大家不要使用一次性用品,一起保护环境,保护我们的地球。虽然这一天的时间活动让我觉得很累很辛苦,但我从中锻炼了自己,并且学到了很多课堂上学不到的东西。也通过这一天的实践,使我有了些关于保护环境的心得体会。

这次活动让我深刻的体会到,当今社会保护环境的重要性,和如今环境问题的严重程度超乎我们的想象,同时也明白“纸上得来终觉浅,绝知此事要躬行”。社会实践使我们找到了理论与实践的最佳结合点。也知道了保护环境光是口头上说是没用的要靠我们的实践行动来证明,通过实践活动才能更深刻的了解如今环境问题的严重性。

在我们亲自打扫社区街道卫生,分发环保传单时。发现虽然有些人对环保,对低碳并不陌生。可是他们在生活中却往往不知从何入手,因而并未采取什么切实的行动。甚至有些人,在我们上前宣传时,会远远的避开,一脸冷漠、事不关己高高挂起的样子。或许我们的环保意识的确有待加强,我们并不能再停留在口头上,而是加强实践,注重树立精神上的榜样。

我就经常看到路边,田地里有很多垃圾,心想:这得多污染环境啊?如果每人都这样到处扔塑料袋、塑料瓶、旧电池……那地球不是变成了大的垃圾场。于是,我总是上前劝住那些人,告诉他们:“乱丢垃圾是会污染环境,破坏大自然的,如果大自然破坏了,我们人类也会无法生存的。”听了我们的话,他们总会红着脸,灰溜溜的走掉,我想他们应该会改变的。

同时,我也感到了无比的高兴和骄傲,因为我又为保护环境,守卫大自然做出了努力。其实,爱护大自然的生态环境是每个人应尽的责任和义务,所以我想说,爱护环境,人人有责。

大家好!

草木葱茏,绿树成荫,鸟语花香,空气清新是我们梦寐以求的家园。地球是人类唯一居住的地方,人类要在地球上安居乐业,就要爱护地球,保护环境,维持生态平衡。“天苍苍,野茫茫,风吹草低见牛羊”多么美的一首诗啊!一下子就把我们带到了大自然风光的遐想中,那么美丽和谐,那么生机昂然,可是现在,人类以飞快的速度改造着大自然,一片片树林倒下,一块块绿色消失,一座座高楼建起,一条条污水流出,我们的生存环境遭到了极严重破坏,大气、水、土地被严重污染,自然界的生态平衡受到很大的影响,湿地、酸雨、荒漠化、沙尘暴一次又一次侵袭着地球,难道这还不足以警示我们,保护环境已刻不容缓!地球就好比宇宙间一艘承载生命的航船,而人类是这艘船上的旅客,现在,这艘船漏水了,为什么?因为人类在船上破坏这艘船不可少的设施——环境,所以,从现在开始,我们应该尽全力补好环境漏洞。

我们可以从身边一点一滴的小事做起,比如多植树造林,爱护周围一草一木,不捕猎小动物,见到垃圾就捡起来等。但这些光凭我们的努力还不够,还要号召我们身边的每一个人为保护环境而做出贡献。绿色是多么宝贵啊!它是生命、是希望、是安慰、是快乐。同学们,当你陷入挫折和失意的时候,当你烦恼的时候,回归大自然吧!拥抱大自然吧!大自然可以陶冶人的性情,平静人的情绪,在林间小路上走一走,在草丛中躺一躺,在大树旁靠一靠,拥抱蓝天绿水,闻一闻泥土的芳香,看看地上的蚂蚁不知疲倦的忙碌,一定可以让你的情绪渐渐平和,愁眉苦脸来,笑逐颜开回。

保护环境,人人有责。让我们行动起来吧!只要努力,绿色一定会再次围绕在我们身旁!

篇17:保护大气环境

全文共 1031 字

20世纪以来,科学技术的发展日新月异,一次又一次新的技术革命促进了世界经济的高速发展,这一方面给人类带来了巨大的物质财富,另一方面也带来了日益严峻的环境和资源问题。人们在分享科技革命成果的同时,也不得不承受着环境公害的苦果,尤其是大气污染。

大气污染有三个最突出的问题:悬浮颗粒物和室内烟尘污染。根据世界组织制订的标准,80年代后期有13亿人口生活在空气悬浮颗粒超标的城市里,超过全球城市居民总数的一半。

空气悬浮颗粒物严重超标的城市多在发展中国家。在发展国家中,如果将空气排放物的浓度控制在世界卫生组织规定的范围内,估计每年可以挽救30-70万人的生命,城市儿童慢性咳嗽的病例每年将减少5000万(发病率降低一半),还有更多的人可以避免慢性呼吸道疾病带来的痛苦,老年人心脏病的发病率也会下降。

空气中铅污染的主要来源就是车辆排放的废气。在许多发展中国家的大城市里,汽车废气的排放量越来越大,已成为最危险的环境问题。在曼谷所做的研究表明,由于汽车废气增加了空气空气中铅的含量,儿童7岁为止智商的数值已下降了7点。对成年人来说,患高血压、心脏病、中风和死亡的危险都会增加.此外,汽车排放的二氧化硫和一氧化氮也在许多城市里造成了严重的空气污染。由此而产生的酸雨还危及森林和水体,给工农业生产带来巨大损失。

人们常常以为大气污染就是工厂排放的废气和尾气等,其实在我们所处的房间里也可能有大气污染,也就是室内烟尘污染。人们对室内烟尘的研究起步较晚,仅仅在16年前才开始重视这种污染造成的危害。在低收入的发展中国家,木柴、秸秆和畜牧粪便便是农村居民的主要燃料。在家庭居室内燃烧这些燃料的结果类似于吸烟,由于浓度高、接触时间长,对健康造成的危害比任何室外空气污染都更加严重.发展中国家有4-7亿人受到室内烟尘的污染,他们主要是贫困地区的农民,其中妇女和儿童受害最深。发达国家室内空气污染的主要来源是合成材料和树脂产品散发的异味和氡气。

我们必须意识到,地球的承受力是有限的,人类社会的发展必须与周围环境之间达到一定程度的协调和平衡。对自然,我们不能虚妄的去“征服”和“战胜”,要精心地加以保护和照拂,否则,我们就会遭到自然界的无情报复.科学技术在利用自然资源方面能发挥巨大威力,同时,在改善环境方面也能起到关键性的作用,因此,我们必须意识到:我们只有一个地球,地球是人类的家园,为了未来必须选择可持续发展的道路,建立人与自然和谐共处的绿色文明。大气污染保护环境作文:让人担忧的大气污染

One day Sun Wukong together with his master and brothers was walking across a river. Suddenly his master fell off the horse by the bad smell of river water. They found the water so dirty that they could hardly breathe.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed. If the river water all over the country is polluted like this, no living things will exist in the water. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

作文【二】

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

Dear editor,

Environmental problems are becoming more and more serious all over the world.

With the development of industry and agriculture, cars make great noises and give off poisonous gas. Because of population expansion and overdevelopment, resources has become less and less. Trees on the hills have been cut down, and waste water is being poured continuously into rivers. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man’s existence.

We must face the situation that exists and take actions to solve our environmental problems. We hope that all these measures will be effective and bring back a healthful environment.

Yours truly
