Remember last years summer vacation, my father and I went for a walk EHu edge, a way, Im kind of shouted thirsty, so my father on the side of the road store bought me a Popsicle. I ate and go, soon finished eating, carelessly threw the ice sticks into EHu. Dad saw, reminded me immediately; "Coco, cant litter oh! If everyone like you to throw garbage in the lake, the beautiful EHu lake becomes waste." Im ashamed of say: "know, next time I must not litter." Dad smiled and stroked my head and said: "the earth is our home, we should protect it, cherish it, let the sky bluer, the water cleaner, the grass is greener." I naughty to say: "oh, that is, everybody has said, the city is my home, clean environment depends on everybody. I understand." From then on, I no longer throw garbage.

I want to take care of the environment is closely related to everyone, so lets start from everyone!

今天,我们读了很多关于保护环境的小短文。我想起曾经在我身边发生的事情。

记得是去年的暑假,我和爸爸一起去鹅湖边散步,走了一段路,我就一个劲的喊口渴,于是,爸爸就在路边的小店给我买了根冰棍。我边吃边走,一会儿就吃完了,随手把冰棍棒往鹅湖里一扔。爸爸看见了,马上提醒我说;“可可,不能乱扔垃圾噢!如果每个人都像你一样往湖里扔垃圾,这美丽的鹅湖不就变成了垃圾湖了。”我羞愧的说:“知道了,我下次一定不乱扔垃圾。”爸爸微笑着抚摸我的头说:“地球也是我们的家,我们应该保护它,爱护它,让天更蓝,水更清,草更绿。”我调皮的说:“噢,那就是大家一直说的,城市是我家,环境清洁靠大家。我明白了。”让从那以后,我再也不乱扔垃圾了。

我想爱护环境与每个人息息相关,所以要从每个人做起!

Where is my home?

Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!

Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.

Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.

【译文】

一些鱼类被迫离开受污染的水,并在天上飞。但不幸的是,空气污染,也使他们不得不戴上口罩。他们每个人都在哭,“我的家在哪里?”这太可怕了!

人类带来了如此多的污染。废物被排入河流和海洋。毒药杀死农业害虫和化学品进入河流和海洋去,太。从工厂有毒气体也使空气这么脏。整个自然界的平衡被毁坏了我们对环保的无知造成的。

As the technology and economic is developing, the environment problem is becoming a severe problem, and the people are seriously affected.

随着科技和经济的发展,环境问题变得严峻,人们也受到严重的影响。

The sustained damage to the environment has caused a serious problem, such as air pollution, sand storm, extraordinary weather, and diseases etc., people suffer from what they have done to the environment.

对环境的持续破坏已经导致了一系列问题,例如大气污染,沙尘暴,反常气候还有疾病等等,人们对环境的破坏让他们尝到苦果。

However. People have realized that it will be too late if they don’t do anything to prevent things from getting worse. For example, there is an “Earth Hour” on a Saturday of March of each year. It is a global movement, usually it lasts from 8:30pm to 9:30pm. It is also called “Light-off for One Hour”. During this hour, all the light will be turned off. The purpose of this movement is not only to save energy, but also to warn the people to realize the importance of protecting the mother earth, and to stop violating the environment.

然而,人们已经意识到,如果他们不做些事情来防止情况继续变糟的话,就太晚了。例如,每年三月的一个周六,有一个“地球一小时”,这是一个全球性的运动,通常从晚上8:30持续到晚上9:30。也叫做“熄灯一小时”。在这一小时里,所有的灯将会被关掉。这个运动的目的不仅仅是节约能源,还警示人们意识到保护地球母亲的重要性,停止对环境的破坏。

Anyway, people and the environment have to keep a balance relationship. People take from the environment, and have to protect it too.

无论如何,人与环境必须要保持一种平衡关系。人从环境索取,也要保护它。

We live in the beautiful earth, its a pity that the earth is every day under the various odor, chemical items, poison, carrion, automobile exhaust, living garbage, factories and so on dirty garbage pollution, make our lovely earth gradually degradation. So to protect the environment is the duty of every man.

Plants and trees is human natural oxygen "manufacturer". But the deforestation, the destruction of the ecological balance of nature; Sand dunes to gobble up the fertile land, white; Floods can be our lovely home. Relentless stuff we clear the river becomes cloudy. Dense forests become sparse clutter, the blue sky become dark, green mountains become bald. Mud-rock flow, dust storm, flood... These disasters are caused by a dirty environment. So we should protect the environment.

How to protect the environment? First of all, cant litter, saw rubbish pick up, is the environment become clean and beautiful. Second, do not arbitrarily trample flowers and plants trees. To plant trees, a variety of flowers and plants.

Electricity, bring us all kinds of convenience, especially gives us light, lit up the colorful world. But we want to save electricity, because electricity is mostly produced by burning coal. Save electricity is to save from coal, less waste, and only enough storage of coal mining in our country in one hundred years! We think, more than one hundred years later, our children and grandchildren to do? So we should save electricity, the usual lamp, use energy-saving light whenever possible.

Protect the environment, everyone duty. Lets start from me, start from now, start from the side of dribs and drabs.

我们住在美丽的地球上,可惜地球每天都饱受着被各种臭气、化学物品、毒汁、腐尸、汽车尾气、生活垃圾、工厂垃圾等等肮脏污染,使我们可爱的地球逐渐退化。所以保护环境是每个人义不容辞的责任。

花草树木是人类的天然氧气“制造厂”。但人们乱砍乱伐,使大自然的生态平衡遭到了破坏;沙丘吞噬了万顷良田;洪水冲毁可我们可爱的家园。无情的杂物把我们清澈的河水变得浑浊。茂密的森林变得稀疏杂乱,蔚蓝的天空变得灰暗,碧绿的青山变得光秃。泥石流、沙尘暴、水灾……这些灾害,都是由肮脏的环境造成的。所以我们更应该保护环境。

如何才能保护环境呢?首先,不能乱扔垃圾,看到垃圾就捡,是环境变得整洁优美。其次,不要任意践踏花草树木。要多植树,多种花草。

电,给我们带来各种便利,特别是给我们带来了光明,照亮了五彩缤纷的世界。但是我们要节约用电,因为电大多是烧煤产生的。节约用电就是节约用煤,少排废气,而在我国储藏的煤只够开采一百多年了!大家想想,一百多年以后,我们的子孙后代该怎么办?所以我们要节约用电,平时的照明灯,尽可能用节能灯。

保护环境,人人有责。让我们从我做起,从现在做起,从身边的点点滴滴做起。

自从人类来到这个世界上,就一直面临着严重的环境问题。但是有的人面临着这么严重的环境污染,却还没有意识到危害的征兆已经降临。

在人类这个赖以生存的地球上,“白色环境污染”相当多。例如:人们上商尝菜市场等购物,都用白色的塑料袋装着。说是因为白色的塑料袋卫生。但是人们用了以后就扔在地上,哪里顾及这会带来多大的污染。

还有大气污染,许多有钱的大老板开着小汽车东奔西跑。在有些人看来,这是富有的表现。但是,在懂得这种污染危害之大的人看来,却是不文明的表现。这些人把整个城市搞的乌烟瘴气,却不以为然自己在破坏环境。

在农村里,有花草树木,空气当然好,环境污染也就会相应减少。但是人们不懂得去保护,反而去破坏。例如:人们滥砍滥伐,把一个充满空气和活力的山砍的伤痕累累,毫无生机。从而造成了严重的环境问题,还有河水里沼泽遍地。

人类面临着这么多的环境问题,怎么能无动于衷呢?为了人类不再受到环境污染的威胁,我们应该发出“保护环境,从我做起”、“关爱一草一木,就是关爱人类的生存”的号召。让我们共同为“保护环境”努力吧!

难道人们就不想有一个天常蓝、水常碧、鸟齐鸣的生态环境吗?如果在这样任意糟蹋下去,几时百年以后,我们的生存环境将会变成:空中弥漫着工厂排出的滚滚浓烟;河里到处流淌着工厂排除的污水……后果不堪设想啊!

人们啊!让我们共同创造一个良好的生存环境吧!

Humans have only one earth, it is human beings rely on natural resources, people want to live a happy happy life, you must consciously to protect the natural environment, care for the earth.

However, in recent years, the earths environment is more and more bad: global warming, hurricane, heavy rain, such as frequent disastrous weather, infectious diseases such as SARS, bird flu, bring serious threat to human life and work and a lot of inconvenience. These are the people constantly "damage" the result of the earth. Large forests have been cut down, green green hill was digging, beautiful grassland into desert, the clear river water turbidity. Trees less, castle peak bald, grassland drought, water dark and make people living environment deteriorate, breathe the air, living environment "occupied" by many harmful things, the virus will take into the body of people, we human beings will suffer from some terrible diseases.

A few days ago, I read in the newspaper that a cartoon: a man sitting on a tree, is he sitting on the branch. "Hum, really funny." Some people may think so. Dont you have to think of it, this is just a funny cartoon? It is just in our? Dont you see, it is warning us: human in the damage to the environment at the same time, also in imperceptible to hurt yourself.

When you walk in the street, if you want to spit, what would you do? If you chose to spit on the ground, you ever think that you hurt yourself? Phlegmy contains a lot of bacteria, when the sun will reproduce and spread. Also, when you cut down a tree, when you cut a piece of grass, when you pour the dirt into rivers, dont you think it is in the destruction of the environment, "injury"?

Proverb is well said: ", predecessors trees descendants cool, "predecessors gave us large tracts of forest and green space, we leave behind is what? Is bare desert, or the thick forest, you must choose the dense woods. What hesitate, let us together voluntarily protect the environment, good care environment, consciously consciously afforest environment, improve our living environment, create a better future!

人类只有一个地球,它是人类赖以生存的自然资源,人们要过上幸福美好的生活,就必须自觉地保护自然环境,爱护地球。

然而,近几年来,地球的环境却越来越恶劣:全球性气候变暖,飓风、暴雨等灾害性天气频繁出现,“非典”、禽流感等传染性疾病时有发生,给人类的生活和工作带来严重威胁和许多不便。这些都是人们不断地“伤害”地球的结果。大片的森林被砍伐,碧绿的青山被挖掘,美丽的草原成荒漠,清澈的河水成浊流。树林少了,青山秃了,草原荒了,清水黑了,使人们生存的环境变坏,呼吸的空气变差,生活的环境被许多有害的东西所“侵占”,病毒就趁机钻进人们的体内,我们人类就会患上一些可怕的疾病。

前几天,我在报纸上看到这样一幅漫画:一个人坐在树梢上,正在砍他坐着的那根树枝。“哼,真好笑。”有些人可能会这么想。难道你就没有想一想,这仅仅是幅好笑的漫画吗?它不正是在讽刺我们吗?难道你就没有悟到,它在警告我们:人类在破坏环境的同时,也在不知不觉地伤害自己。

当你走在大街上,如果你想吐痰,你会怎么做呢?如果你选择了吐在地上,那么你想过没有,你在害自己吗?一口痰含有大量的病菌,当太阳着时就会繁殖、传染。同样,当你砍伐一棵树,当你挖掉一片草,当你把脏物倒进河流,难道你没有觉得这是在破坏环境,“伤害”自己吗?

俗语说得好:“前人栽树,后人乘凉”,前人给了我们大片大片的森林,绿地,我们留给后人的是什么?是光秃秃的荒漠,还是茂密的树林,你肯定选择的是茂密的树林。那还有什么犹豫的,让我们大家一起自觉保护环境,自觉爱护环境,自觉绿化环境,改善我们的生活环境,创造美好的未来!

As revolu??es do Rio Grande do Sul e do Pará amea?avam a integridade do Império. A nacionalidade mergulhava num ambiente de dúvida e de incerteza. As revoltas que se faziam para restaurar a normalidade acabavam por agravar os males, em círculo vicioso.

A sociedade debatia-se entre doutrinas mal assimiladas, sem encontrar interpreta??es certas, e radicalizava-se em partidos, fac??es e grupos.

同学们一天中大部分时间都在学校里度过,学校为我们创造了良好的学习环境,因此,校园环境需要同学们来维护保护校园环境应该做到以下几点:

(1)不随地乱扔果皮、纸屑。同学们吃了零食以后,经常把那些塑料带随地乱扔,给校园环境带来了重大危害。想想看,如果你生活在一个满地都是垃圾的学校里,心情还会舒畅吗?学习还会搞得好吗?

(2)不能破坏花草树木。学校里栽着许多绿叶繁茂的树木,五彩缤纷的花朵,碧绿的草坪,它们提供给我们新鲜空气,它们不但给我们带来了美的享受,还让整个校园充满了清香。所以不能让它们受伤害。不能用刀在树杆上刻字,不能乱摘花朵,不能残踏草坪。

(3)见到地上有垃圾要随手捡起,扔进垃圾桶里。

(4)如果看到有人正准备随地乱仍垃圾,就要告诉他不要乱扔,然后叫他扔进垃圾箱里。

(5)不在墙壁上乱写乱画。墙壁是洁白无暇的,可是有的同学就是手闲不住,偏偏要在墙上画上那么几笔,这样就不美观了。

(6)积极参加保护校园环境的劳动。学校经常组织一些保护校园环境的活动,比如锄草、擦墙壁等等,这些活动我们要经常参加,为保护校园环境贡献一份力量。

人类的破坏并不是近代,在很久以前人类就一直在破坏生态环境。曾看过一篇报道,证实了澳大利亚塔斯马尼亚岛上巨型袋鼠和有袋犀牛,有袋豹在早期人类出现之前仍漫游在岛屿上。该发现证明了塔斯马尼亚岛上大型史前动物的灭绝是由于人类打猎导致的,而并非是由于天气恶劣所形成的灭绝。

曾经有人说“如果全中国的人给我一元,我就可以发财了。”的确,一粒纽扣电池可以污染60万升水,中国一共有14亿人口,如果每个人扔一粒电池到水中,就会污染到84万亿的水,而地球一共只有140亿亿升水,可见人们日常的生活习惯影响之大。

大自然的报复正向我们一步步逼近,大自然的报复是无法抵御的。所以我们应该从现在做起,从自己做起来保护环境。顺应时代发展,我们最先做到的就是低碳生活。我们要做到尽可能的步行外出,或者骑自行车,减少二氧化碳排放量。我们也要学会节电,将手机的亮度调低点,将空调温度调高一度。这些细小的动作对我们来说非常简单,然而日积月累,它们就有可能可以改变我们的命运。

篇15:当前,威胁人类生存的十大环境问题是

全文共 2072 字

+ 加入清单

(一)全球气候变暖

由于人口的增加和人类生产活动的规模越来越大,向大气释放的二氧化碳(CO2)、甲烷(CH4)、一氧化二氮(N2O)、氯氟碳化合物(CFC)、四氯化碳(CCl4)、一氧化碳(CO)等温室气体不断增加,导致大气的组成发生变化。大气质量受到影响,气候有逐渐变暖的趋势。由于全球气候变暖,将会对全球产生各种不同的影响,较高的温度可使极地冰川融化,海平面每10年将升高6厘米,因而将使一些海岸地区被淹没。全球变暖也可能影响到降雨和大气环流的变化,使气候反常,易造成旱涝灾害,这些都可能导致生态系统发生变化和破坏,全球气候变化将对人类生活产生一系列重大影响。

(二)臭氧层的耗损与破坏

在离地球表面10~50千米的大气平流层中集中了地球上90%的臭氧气体,在离地面25千米处臭氧浓度最大,形成了厚度约为3毫米的臭氧集中层,称为臭氧层。它能吸收太阳的紫外线,以保护地球上的生命免遭过量紫外线的伤害,并将能量贮存在上层大气,起到调节气候的作用。但臭氧层是一个很脆弱的大气层,如果进入一些破坏臭氧的气体,它们就会和臭氧发生化学作用,臭氧层就会遭到破坏。臭氧层被破坏,将使地面受到紫外线辐射的强度增加,给地球上的生命带来很大的危害。研究表明,紫外线辐射能破坏生物蛋白质和基因物质脱氧核糖核酸,造成细胞死亡;使人类皮肤癌发病率增高;伤害眼睛,导致白内障而使眼睛失明;抑制植物如大豆、瓜类、蔬菜等的生长,并穿透10米深的水层,杀死浮游生物和微生物,从而危及水中生物的食物链和自由氧的来源,影响生态平衡和水体的自净能力。

(三)生物多样性减少

《生物多样性公约》指出,生物多样性“是指所有来源的形形色色的生物体,这些来源包括陆地、海洋和其他水生生态系统及其所构成的生态综合体;它包括物种内部、物种之间和生态系统的多样性。”在漫长的生物进化过程中会产生一些新的物种,同时,随着生态环境条件的变化,也会使一些物种消失。所以说,生物多样性是在不断变化的。近百年来,由于人口的急剧增加和人类对资源的不合理开发,加之环境污染等原因,地球上的各种生物及其生态系统受到了极大的冲击,生物多样性也受到了很大的损害。有关学者估计,世界上每年至少有5万种生物物种灭绝,平均每天灭绝的物种达140个,估计到21世纪初,全世界野生生物的损失可达其总数的15%~30%。在中国,由于人口增长和经济发展的压力,对生物资源的不合理利用和破坏,生物多样性所遭受的损失也非常严重,大约已有200个物种已经灭绝;估计约有5000种植物在近年内已处于濒危状态,这些约占中国高等植物总数的20%;大约还有398种脊椎动物也处在濒危状态,约占中国脊椎动物总数的7.7%左右。因此,保护和拯救生物多样性以及这些生物赖以生存的生活条件,同样是摆在我们面前的重要任务。

(四)酸雨蔓延

酸雨是指大气降水中酸碱度(PH值)低于5.6的雨、雪或其他形式的降水。这是大气污染的一种表现。 酸雨对人类环境的影响是多方面的。酸雨降落到河流、湖泊中,会妨碍水中鱼、虾的成长,以致鱼虾减少或绝迹;酸雨还导致土壤酸化,破坏土壤的营养,使土壤贫瘠化,危害植物的生长,造成作物减产,危害森林的生长。此外,酸雨还腐蚀建筑材料,有关资料说明,近十几年来,酸雨地区的一些古迹特别是石刻、石雕或铜塑像的损坏超过以往百年以上,甚至千年以上。世界目前已有三大酸雨区。我国华南酸雨区是唯一尚未治理的。

(五)森林锐减

在今天的地球上,我们的绿色屏障——森林正以平均每年4000平方公里的速度消失。森林的减少使其涵养水源的功能受到破坏,造成了物种的减少和水土流失,对二氧化碳的吸收减少进而又加剧了温室效应。

(六)土地荒漠化

全球陆地面积占60%,其中沙漠和沙漠化面积29%。每年有600万公顷的土地变成沙漠。经济损失每年423亿美元。全球共有干旱、半干旱土地50亿公顷,其中33亿遭到荒漠化威胁。致使每年有600万公顷的农田、900万公顷的牧区失去生产力。人类文明的摇篮底格里斯河、幼发拉底河流域,已由沃土变成荒漠。中国的黄河流域,水土流失亦十分严重。

(七)大气污染

大气污染的主要因子为悬浮颗粒物、一氧化碳、臭氧、二氧化碳、氮氧化物、铅等。大气污染导致每年有30-70万人因烟尘污染提前死亡,2500万的儿童患慢性喉炎,400-700万的农村妇女儿童受害。

(八)水污染

水是我们日常最需要,也上接触最多的物质之一,然而就是水如今也成了危险品。

(九)海洋污染

人类活动使近海区的氮和磷增加50%-200%;过量营养物导致沿海藻类大量生长;波罗的海、北海、黑海、东中国海(东海)等出现赤潮。海洋污染导致赤潮频繁发生,破坏了红树林、珊瑚礁、海草,使近海鱼虾锐减,渔业损失惨重。

(十)危险性废物越境转移

危险性废物是指除放射性废物以外,具有化学活性或毒性、爆炸性、腐蚀性和其他对人类生存环境存在有害特性的废物。美国在资源保护与回收法中规定,所谓危险废物是指一种固体废物和几种固体的混合物,因其数量和浓度较高,可能造成或导致人类死亡,或引起严重的难以治愈疾病或致残的废物。

篇16:关于癌症与环境的英语作文

全文共 1068 字

There are two main causes for cancer: heredity and environment. We can do nothing to change our heredity, that is, the basic physical characteristics that arepassed on to us by our parents. However, we can do a great deal to control our environment, which may account for eighty to ninety percent of all cancers.
