导语:地球是我们从后代手中借来的、环保不分民族,生态没有国界不要旁观,请加入行动者的行列今天节约一滴水,留给后人一滴血。面是yuwenmi小编为大家整理的优秀英语作文,欢迎阅读与借鉴,谢谢!

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. Trees on the hills have been cut down,and waste water is being poured continuously into rivers.

Furthermore,wherever we go today, we can find rubbish carelessly disposed. 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 mans existence.

We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.

【参考译文】

全世界的环境问题在变得越来越严重。随着工农业的发展,汽车制造噪音、排放毒气,山上的树木被砍伐,污水不断被排入河里。另外,无论我们走到哪里,到处可见随意丢弃的垃圾。整个地球生态平衡正在改变,环境的巨大破坏已带来负面影响,甚至对人类生存带来巨大威胁。

我们必须面对现实,采取行动解决环境问题。例如必须通过新的法律严格控制工业污染问题,大众必须接受污染危害的教育等。我们希望这些措施的有效实施能带给我们一个健康的环境。

篇1:家乡环境污染

哦!家乡变了,家乡变了,我怀着无比激动的心情来到家乡。

下了车,眼睛突然一亮,哇!家乡简直是梦幻美丽的天堂。眼前,是一排排苍翠挺拔的大树,像一位位士兵守卫着这梦幻般的仙境。脚下的路更加宽阔平坦,不再蜿蜒崎岖。向前走10分钟,一条清澈见底的小溪便印入眼帘,水底的鱼虾清晰可见,它们无忧无虑地在小溪里穿梭,快乐的好像神仙一样。在阳光的照耀下,水面破光粼粼,像一面洁白无瑕的璞玉。小溪旁,是一片翠绿的草坪,几棵小草,伸着懒腰,从土地里钻了出来,探视着这五彩缤纷的世界;小花涨红了脸,呼吸着春天的香气息。

家乡的变化可真大啊!想当年,家乡的环境十分恶劣:山上,一群肌肉结实,身体强壮的年轻男子,拿着一把把锋利的电锯,无情地把高大粗壮的树木砍伐一空。生活在山林的小动物都仓皇而逃,过着定无居所的日子。生活在小溪旁的人们更受着百倍的煎熬,溪水恶臭浑浊,鱼虾奄奄一息。溪旁的小草面黄肌瘦。无精打采,小花也垂头丧气,没有了往日的生机。更恐怖的是,环境的污染使得可怕的自然灾害降临到家乡。瓢泼大雨使山体滑坡,严重的泥石流,造成了许多人财产受损。幸亏人们对家乡长生了保护意识,在荒山上植树造林,把小溪的垃圾清除一空……这才把家乡从死亡的边缘拉了回来。

我们美丽的家园需要爱,请保护环境吧!让我们的地球永远拥有美丽、青春的活力。

篇4:英语作文:经济发展与环境保护

Economic development and environmental protection are a pressing issue primarily for developing countries where, in trying to catch up with developed countries, they have to consume natural resources on an unprecedented scale. This has seriously polluted our environment and, with the global environmental campaign gaining momentum, many people in China call for the precedence of environmental protection over economic development.

Any attempt to pose economic development and environmental protection as diametrically contradictory is simple-minded. Since no country is willing to stop its economic development, the best way is to strike a balance between the two and to heighten the environmental awareness of those solely concerned with economic development.

European countries both economically developed and environmentally friendly can serve as perfect examples for China. Their success story in both undertakings illustrates that environmental protection does not mean a complete standstill of economic activities or exploitation of natural resources, but rather an active development and application of effective technologies to minimize environmental consequences. In Germany, environmental protection has become part of economic development as it boasts the world s most successful environmental industry. With a developed economy, we are well equipped to develop sophisticated technologies that can effectively safeguard our environment.

唉!看来这个周末骑自行车的愿望又泡汤了!为什么呢,因为天气预报显示:未来几天,杭州都是雾霾天。爸爸说,在这样的天气里,如果在户外骑自行车或是跑步,我们就变成了雾霾的“吸尘器”,久而久之,几乎等于慢性自杀--我们在呼吸过程中,悬浮在空气里的灰尘都“钻”到肺里去了。特别是在运动的时候,随着呼吸的加剧了,我们吸进去的坏分子--雾霾就更多!

记得我们在课堂上学过:秋天是“秋高气爽”的日子,空气应该是最好的。可是最近这么多天,我们见到最多的却是灰蒙蒙的世界。一开始我开心,城市朦朦胧胧的“罩”在雾里头,好像是海市蜃楼,我觉得自己就像是进入了烟雾缭绕的蓬莱仙境。可是爸爸妈妈给我泼了一盆冷水,他们告诉我,这不是“晨雾”而是“雾霾”。

“雾霾”?我好奇地在网上查了一下这个新鲜的名词。原来,“雾霾”是雾和霾的组合词。但是雾和霾的区别十分大。雾是由大量悬浮在近地面空气中的微小水滴或冰晶组成的;而霾是由空气中的灰尘、硫酸、硝酸等组成的,它能使大气浑浊,视野模糊并导致能见度恶化。中国不少地区把阴霾天气现象并入雾一起作为灾害性天气预警预报。统称为“雾霾天气”,如遇雾霾天气,要做好防毒措施。汽车尾气、工业废气等是导致雾霾的罪魁祸首。

我不要做城市里的“吸尘器”。可我们现在有什么好的办法来“降雾驱霾”?我想我用孙悟空的“定身法”,让城市里的汽车都无法排放尾气;我想用铁扇公主的芭蕉扇,吹走城市上空的雾霾;我想用观音菩萨的“净瓶”,把空气里的粉尘洗干净;我想请龙王降一场大雨,把城市里的灰霾冲刷得干干净净!其实,最好的法宝是我们大家一起来呵护地球:减少开车,环保出行;减少污染保护环境!

近日,欧洲空间局发射升空的地球环境监测卫星传回首批数据照片。科学家计划,不久将根据地球环境监测卫星传回的资料出版地球环境月度报告。

经过欧洲14国十多年的共同努力,欧洲巨型地球环境监测卫星“恩维萨特”于2002年3月1日被送入太空。

“恩维萨特”卫星被科学家戏称为巨型“环境间谍”,是以阿斯特利乌姆航天公司为首的欧洲50多家公司联合制造完成的,重量为8111公斤,展开宽度26米,卫星运行在距地面800公里的太阳同步轨道,每100分钟环绕地球一周,卫星携带的仪器对地球进行观测,周期为35天,使用寿命为5年,其造价、发射费用及5年运转费用为24亿欧元,是欧洲空间局生产的最大、最昂贵、最先进的地球环境观测卫星,也是目前世界上惟一一颗准实时向地面传送观测数据的观测卫星。

该环境监测卫星具有两大功能:一是普查地球资源;二是监测地球环境。欧洲空间局一支450人的科研队伍将根据卫星传回的资料评估人类活动对环境的影响,其中两大研究课题是臭氧层破坏和环境污染。该卫星的使用大大丰富了环境和气候变化的科学数据,能帮助科学家观测地球变暖、臭氧减少、海洋变化和冰层、植被消亡等现象,研究地表荒漠、火山爆发、洪水与厄尔尼诺等形成的原因,以及监控地球污染状况,并传回地球生态系统间相互作用的相关数据,找到地表污染源与污染原因。

德国政府发布的新闻公告表示,由于“恩维萨特”环境卫星配备先进的探测分析仪器,传回的数据将比目前所有同类卫星更精确,“达到其他卫星无法达到的质量”,因此它将有助于监督旨在控制全球变暖的《京都议定书》的执行情况。

However, I am sorry to have witnessed some improper behaviour among us students: scribbling and littering everywhere. Not only does it destroy our school environment, it is also a spoiler of the image of our school.

This issue is now crying out to be solved and it should be a common concern for the school administration, staff, and all the students. In my humble view, the school should place more dustbins around the set up specific rules against those rude practices. At the same time, students should be encouraged to develop good habits and enough awareness of environment protection.

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。

汞污染

汞是唯一在常温下呈液体的金属元素。俗称“朱砂”。汞可溶于水,空气中。它巨大的毒性令人谈之色变。它主要来源于电池等物品。据统计1970~1979年全世界直接向水体排放的汞总量达1.6万吨!排向大气的汞量也达10万吨。当水中或空气中的汞浓度过高时,会导致树木枯死,人类患上因汞摄入过高引发的病症,如日本南部九州湾有一个叫水俣的小镇,这里居住着4万居民,以渔业为生。1939年开始,日本氮肥公司的合成醋酸厂开始生产氯乙烯,工厂的生产废水一直排放入水误湾。该公司在生产氯乙烯和醋酸乙烯时,使用了含汞的催化剂,使废水中含有大量的汞。这种汞在水体中,被水中的鱼食用,在鱼体内转化成有毒的甲基汞。人食用鱼后,汞在人体内聚集从而产生一种怪病:患者开始时,只是口齿不清,步履蹒跚,继而面部痴呆,全身麻木,耳聋眼瞎,最后变成神经失常,直至躬身狂叫而死。1972年据环境厅统计,水误镇共患水误病180人,死亡50多人,就在新线县阿赫野川亦发现100多水误病患者,8人死亡。据报到,患者人数远不止此,仅水误镇的受害居民,即达万余人。

环保事业说大很大,说小很小。往大的说,可以造成成片的水域污染。往小了说,只要我们每人从身边的小事做起,人人环保低碳,环保事业也可以是一件很小的事。如果我们少用些塑料袋,少乱丢些垃圾,那么这个世界上便会少些随风飘舞的白,多些生机勃勃的绿;也会少些乌黑肮脏的河,多些碧蓝清澈的湖。

如果我们每个人在地上看见一个塑料袋不是直接走过,而是弯腰拾起;如果我们每人不是随意乱丢垃圾,而是做到合理分类垃圾;如果我们每人都少用些塑料袋,多用些环保袋。那么我相信地球母亲会少些愤恨的泪水。

一:环境污染的根源

在十年前的中国,大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样,看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产,燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝,随着中国经济的迅速发展,人们生活水平的不断提高,人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题,其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬,专家们各有其立场,但对于普通百姓来说,全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖,海平面上升,冰川融化,动植物灭亡的问题,人们大多数是在电视新闻或报刊杂志上看到,恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题,人们开始关注更多的便是最近发生在北京,广州,武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康,更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象,国外专家学者很多年前便开始研究。

那么何为灰霾?灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物(PM2.5)和臭氧()、二氧化氮()、二氧化硫()、挥发性有机物()等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关,还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种,直径小于2.5微米的颗粒物(PM2.5)和直径小于10微米的颗粒物(PM10)。虽然两种形式的颗粒物都对人类健康有极大的危害,PM2.5被普遍认为是更危险的,因为它的体积小,大约只有人类头发宽度的1/30。人们在呼吸时,PM2.5可以进入人类肺组织深处,甚至进入血液,造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此,PM2.5可以传播的更远,停留在空气的时间越长,影响更大的人口。PM2.5和PM10的主要来源包括机动车,电厂和其他工业源,以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合,可以在城市或农村地区天空一片阴霾,而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因,像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围,当地空气干燥,白天阳光充足。到了晚上,地表面冷却很快。地面附近的空气变冷,而上层空气都比较热,形成逆温。北京市位于华北平原的西北边缘,背靠太行山余脉和燕山山脉,面对辽阔的华北平原,东南距渤海约150公里, 地处暖温带半湿润地区,气候属于暖温带半湿润大陆性季风气候,四季分明,春季多风和沙尘,夏季炎热多雨,秋季晴朗干燥,冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远,周围地形如盆地,集热容易散热难,河湖多、晚上水汽多,城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市,而且城市海拔较低,周围至少有一面是高地,都分布在低于南北纬50度的地方。这些地区夏季阳光明媚,天气温暖干燥。在城市的盆地地区,逆温现象十分普遍。夏季的阳光使地面温度升高,城市街道和建筑物迅速升温,与炎热的物体表面接触的空气温度升高。通过对流空气向上运动,但它却不能穿透逆温层,因为上面的空气温度更暖且密度更小。空气聚集,但连续的对流形成了垂直的循环,使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下,通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集,大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响,学者称它为街谷模型。随着城市化的加速,城市及城市周边的自然生态系统逐渐被人工生态系统取代,取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续,高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时,风速迅速降低并产生特殊的湍流,使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用,因此,对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市,尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物(PM)浓度和40%的二氧化氮(NO2)浓度。因此,通过对植被的合理利用能过创造一个有效的城市污染过滤膜,对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题,相反它是一个长久的问题,从它如何形成,加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象,它只是地球环境污染的一个缩影。我们更应该探究它的根源问题,什么才是它形成的根源,什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题,但我们可以通过减少排放源,通过增加植被,加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼,越来越发达便利的交通,相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了,人们是否会怀念那晴朗的蓝天,向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

就最近这几年来看,随着各地区的经济迅猛发展,环境污染问题也越来越严重,保护环境,维持生态平衡也成为了我们每个公民应尽的责任和义务,也是为了社会更好发展的一项重要举措!

何为环境?从哲学的角度来看,所谓环境,主要指我们所研究的主体周围的一切情况和条件。对于人来说,环境是指人生活于其中,并能影响人的一切外部条件的综合。人的生活离不开好的环境,在人类几百万年的历史进程中,环境对开创人类文明和进步发挥着巨大作用。

大气资源、水资源、土地资源等等,都是让人类得以生存的物质基础;而森林资源、矿藏资源等资源又为人类的不断发展提供物质,创造出地球上高度的人类文明。但是,人类在开发利用环境资源的同时,也对自己的生存环境产生了一系列环境问题。

在我们身边就有很多污染环境的污染物,例如说:大量的生活废弃品,塑料袋(也称白色垃圾),一次性木筷,一次性饭盒,果皮纸屑。污染物对环境来说,毫无疑问,肯定有很大的危害,例如动物的腐烂的尸体会影响环境卫生,而且还会滋生细菌。饭店、餐馆认为很卫生的一次性木筷,使用后随便一扔,影响了市容,破坏了环境。。

现在像我们柳疃镇、青乡乡,最近电网部门纷纷撤除喷水机器的使用。喷水机的使用对环境的污染更加恶化、污染了水资源对人们的身体健康危害甚大。人类的活动会使大量的工业、农业和生活废弃物排入水中,使水受到污染。又例如说,我们北部渤海湾受到工业、印染厂的废弃物排放大量鱼虾死亡,地区农民上海捕鱼,鱼的体内含有大量化学物质对人们的身体健康造成了危害。据资料统计,目前,全世界每年约有4200多亿立方米的污水排入江河湖海,污染了5.5万亿立方米的淡水,这相当于全球径流总量的14%以上。1984年颁布的中华人民共和国水污染防治法中为“水污染”下了明确的定义,即水体因某种物质的介入,而导致其化学、物理、生物或者放射性等方面特征的改变,从而影响水的有效利用,危害人体健康或者破坏生态环境,造成水质恶化的现象称为水污染。水的污染有两类:一类是自然污染;另一类是人为污染。当前对水体危害较大的是人为污染。水污染可根据污染杂质的不同而主要分为化学性污染、物理性污染和生物性污染三大类。

最近,我发现政府部门、昌邑环卫局开始大力整治环境,沿街排查污染源,青乡街也定点安置了便民垃圾桶,替代了原来垃圾围绕街道,臭气熏天的状况。各个村庄开始整治村内环境的污染源,使街道、村庄焕然一新!而这不是主要的,更重要的是我们每个人自觉保护环境,保护我们赖以生存的家园,为了我们更为了我们的后代,树立好榜样,奠基好基础,让我们的家园更加美丽、更加丰富多彩!

所以呢!环境与我们的生活密切相关,保护环境卫生从我做起,从现在做起:不随地吐痰;不乱扔垃圾;废弃电池和塑料袋要处理好;多植树造林,不践踏草坪;不污染水源。保护环境,我们有责!看你的行动喽!

小建议:家庭生活中的塑料瓶可以做成装饰品,可回收物品可以卖出,换来金钱买实用的东西岂不很好?一次性木筷消毒清洗一下可以做成装饰品,你也能开小店赚大钱了!化废物为贵宝,让自己的心情更舒畅,让自己的心灵更纯洁,让自己的家庭更温馨!

三:环境污染

在二十一世纪的今天,人类赖以生存的地球环境越来越恶劣,灾难频发,旱灾、洪涝灾害、土地沙漠化、地震、全球气温上升、海啸等等过去,以我所受到的信息宣传,简单以为环境污染只是浓烟滚滚,或者水面上漂浮着垃圾、发出恶臭,蚊虫成堆、尘土飞扬等等。但是,今年从网络、报纸、广播、电视、人们的关注里,我似乎明白;现实的情况要糟得多。西南五省大旱,就是我们自己想都没有想到的原因,专家分析:因为在过去10几年中,西南从新西兰大量引进桉树速生林,为了求短期的经济利益,毫无限制的大面积种植,以用来工业造纸,从而导致物种生态环境失衡,形成地下水严重缺失。俗话说,十年树木,百年树人,可这种桉树两三年就成材,是一种巨大的抽水机和抽肥机,不断侵蚀着其他植物物种的生存空间,而当地人却沉浸在多种树就可以保护环境的僵化错误的指导思想中,不断的在往恶性循环上发展,正是这个想到想不到的原因最终导致西南几百年的大旱灾。在报纸上,我看到温总理在一片干涸开裂的耕地上,捧着一颗枯死的禾苗,只说了一句话:“痛定思痛!”云南拥有大片的原始森林,风景名胜众多,地理环境独特,自古以来就是一个山清水秀,气候宜人的好地方,可是为了种植这种桉树,大量砍伐原始森林,想象这些经过几十年甚至数百年才形成的树木,仅仅是为了去满足最快速度的造纸而被破坏,真是让人可惜,并且痛心。据说旱灾的另一个原因,就是所有的大江小河都修起了水电站。对这一点我有自己的感受,早两年湘江的水面多么宽广,可是上游修了一个水电站后,下游的水明显减少,甚至连河床都经常露出来,同时影响到了城市自来水的引水工程,我都有这些感受,那些江河里小鱼虾们感受就应该更深了。前些天报纸上又爆出地沟油事件,报纸上说地沟油是别人吃完的饭菜倒进垃圾桶后,一些黑心商人把这些进行简单的提炼加工后,不但闻不出异味,加入香精后吃起来还挺香,但是对人体危害很大,我现在都不敢随便在外面吃东西了。环境污染的问题日益严重,影响到了我们生活的方方面面,对此我感到非常的忧虑。

四:河道为什么会污染

在我们学校旁边,有一条小河,听长辈们说,原来这里的河水清澈见底,河里鱼虾成群,夏天人们喜欢在水里游泳,还直接取水饮用呢!可如今,河水不但变得混浊,有时还有臭味呢!

为什么河水会发生翻天覆地的变化呢?经过我们全班同学的观察分析,河水污染有许多原因 。首先,人们不重视环保,乱倒垃圾。如有一次,我去张微家去玩,吃了一根香蕉,问她的妈妈:“阿姨,香蕉皮扔哪里?”只见她从我手中拿过香蕉皮,又随手用力一扔,扔进了小河,说:“这就是我们家的垃圾桶。”甚至有人把死猫死狗也扔进去了,这时,如果你从旁边经过,一阵阵臭味就会扑鼻而来。我真是不明白,人们为什么不多走几步把垃圾扔到垃圾箱里让垃圾车运走呢?。其次,人们家里的化粪池的排污口就直接通向小河。特别是我们学校,大小便没有经过处理就流进了小河,让人看了真是恶心。河水不变臭才怪呢!还有人们给庄稼喷了农药后,就在河里洗药筒等等。由于各种原因使河水变得越来越脏,甚至发臭,更不用说饮用,就连小鱼也快要无家可归了。

我想向人们呼吁:“水是生命的源泉,没有水就没有生命,就没有我们这个美丽可爱的家园,所以请你们不要再伤害小河了,难道你们就没有看见小河在哭泣吗?”

我们的环境污染我们的环境污染我们现在的生活比以前好得多,但环境跟以前简直就不能比。以前的空气清香并掺和着花草的芳香,河水清澈见底。而现在呢?汽车排出的废气和工业废气相当多,河水臭气直出。我们大家为了过上好生活,都买汽车,但车主们有没有想过这样的量使用汽车的后果。

有些地方之间的距离非常近,但车主们不想跑,就直接开汽车。假如一辆汽车一天排放一千克废气,那么中国每天大约有几千万辆汽车在行驶,那么一天就要排放几千万千克的废气。这个数目仅显示一天一千克的废气排放量和仅计算中国的废气排放情况。工厂的污染更严重,水和空气都要被污染。大量的废水排入大海和河流之中,以致大量的鱼虾、水中植物死亡和大量的水资源被污染。

我们地球上的资源也在一天一天的减少。大量可回收的品中只有3%是被回收并再生的。许多白色垃圾造成了白色污染。我心中的家园是和以前差不多的,可是这是很难挽回的。为了我么大家共同生活了几千万年的蓝色星球?——地球的美好未来而努力吧!
