pring is tht best season of the year. the weather gets warmer and warmer. my clas i'amates and i took a one-day sightseeing around our city.the scene was pretty. but when we saw the rivers along our city, i felt very sorry, and thoughit a lot.

with the development of modern agriculture and industry, more and more waste water is being poured into rivers. it has caused serious pollution. the river is becoming so dirty that no living things can live in it. the river is giving off a terrible smell.

we make an urgent appeal that measures should be taken to cope with the situation. our government should start building various facilities such as sewage treatment!plant and encourage scientists to work out more and better ways to reduce the pollution of water. water is tho source of our lives. it is very important to protect water.

my classmates and i had an outing this spring. we had a good time. but meanwhile i noticed that water pollution in our city was becoming more and more serious.

on our way, we could see women washing clothes in the river. litter was floating on the river. waste water produced by a chemical factory was being discharged into the river. we did not see any fish in the river. the fiver was not so clear as before. water quality was very bad. i am worried

about it because water is important to all living things. man can not live without water. i hope people pay more attention to this problem, especially the government. try to control the pollution of water as early as possible.

at last i would like to say, "to protect water is to protect life."

water pollution is caused by waste from factories and cities. oceans are able to clean themselves, but certain seas, once they become dirty, are not able to do so. one example is the mediterranean which lies between europe and africa. it has onlyeone narrow entrance to the ocean in the west. on quarter of the shores of the mediterranean are polluted and are no longer safe for swimming, as a lot of diseases are present in the water. in most places it is not safe to eat the fish.

lakes also have the same problems. lake baikal in asia was once the cleanest in the world, with over 700 different kinds of plant and animal life. now, however, the waters of this great lake, which is also the worlds deepest (over 1,740 metres), have been dirtied by waste from a chemical factory.

in 1988 an oil tanker hit a rock off the northwest coast of alaska. 35,000 tons of oil poured into the sea. the accident was one of the worst in history. more than 34,000 birds and 10,000 animals were killed. 4,800 square kilometres of ocean were polluted.

一天，兔子咪欣和小鸟理理一起到溪边散步，咪欣觉得很口渴，就迫不及待的跑到了小溪边喝了一口水，然后他们就去小象长鼻儿家玩，突然兔子咪欣肚子痛，理理很紧张，不知怎么办好。忽然，他想起了河马镇长雷尔那，于是就往河马镇长雷尔那家跑去，把咪欣肚子痛的事告诉了河马镇长雷尔那。不一会儿，也跑来了许多其它动物，都说喝了小溪的水后肚子痛，雷尔那觉得奇怪，就找来了山羊医生音利，因利为大家检查，发现大家都中毒了，于是，它就化验小溪的水，结果小溪的水是被污染了。于是，河马镇长雷尔那就派其它动物去寻找小溪被污染的原因。

第二天，动物们发现远处有一间工厂，原来这间工厂是乌鸦塞丝开的，它把工厂排出的污水流入小溪，使溪水受到了污染。于是雷尔那马上去阻止它说：“塞丝，你知道你已经把溪水污染了，昨天，许多动物因为喝了受污染的水而中毒了，你再不停止生产，整个动物乐园就会给你毁掉了。”塞丝听了惭愧地低下了头，就把工厂停办了。

因利很快把动物们的病治好了，然后动物们一起把动物乐园里受到污染的地方搞干净了。

第三天，动物乐园开了个会，雷尔那对动物们说：“水是我们的生命之源，我们不能为了挣钱，就随意地污染水源。我们没了水就不能再生活，所以大家要好好保护我们的小溪，不要让它受到污染。忽然，乌鸦阿丝站起来一本正经地说：“真对不起，我不应该为了挣钱而污染了水源，让大家因喝了被污染的水中毒了。”散会后，阿丝回家写了许多道歉条，然后派到各家各户。大家看了阿丝的道歉信，就纷纷到阿丝家去，告诉它不要太内疚，大家都已原谅它了。河马镇长雷尔那还对阿丝说：“你真是个知错能改的好孩子，大家都被你的真诚打动了。”

从今以后，动物乐园再也没有人开工厂了，动物们经过这件事后，更加懂得珍惜精灵乐园的一切，精灵乐园也越来越可爱了。

third，across our society ，relevant protection awareness has not built up so that people havent formed a habit of using green product and saving energy as much as possible.just for the sake of convience to go out，people rely more and more on travelling and working by car while car is the main cause for the haze weatherto settle this problem，a series of meaures should be taken as follows.first ，we should strengthen air monitor to lower the levels of small particulate pollutants.second，we should enact more strict laws and regulations and keep perfecting our current law on environmental protection to regulate people s daily action and the industrial production and punish those factories that ignore the protection and keep emitting dangerous material that cause haze. third，we should develop green and energy-saving energy to lower the emission of haze and improve air quality.as far as i am concerned ，if we work together to be able to do such measures ，our environment will getting better and better and haze weather will vanish completely.

地球现在已经被人类们破坏，变得越来越虚弱……

地球的二氧化氮污染严重：德国科学家日前利用卫星数据和一种先进的仪器，绘制了一幅地球上空二氧化氮的分布图。图像显示，一些地区的大气中二氧化氮含量过高，污染严重。自然界中的二氧化氮是由闪电或者微生物形成的。但是，使用矿物燃料、重工业密集和交通繁忙等原因都会造成空气中二氧化氮的增加。这种气体的密度过大会导致呼吸疾病、肺损伤，甚至可能在接近地面的高度形成有害的臭氧。因此，长久以来，空气中二氧化氮的含量都是判断一个地区污染程度的重要标志。从科学家绘制的二氧化氮分布图看，欧洲和北美洲的`一些大城市上空二氧化氮密度很高，这可能与这些地区机动车辆过多有关。从分布图判断，东南亚和非洲地区上空的二氧化氮含量也很高，专家估计原因可能是这些地区的植被遭到焚烧。让人惊讶的是，在这幅地图上，红海和印度洋中的船舶航道清晰可辨。科学家指出，这说明由于海洋运输频繁，造成了海洋上空严重的大气污染。我看了这一些我的心里感到非常的痛苦，我看到自己的国家，自己的地球逐渐走向灭亡……逐渐走向虚弱……我不希望看到我们的地球被自己给破坏。此外，还有许多因污染造成的噩耗！由于地球的污染空气污染影响日照地球上的阳光越来越少：美国气象学家在一份刚刚发表的报告中指出，过去50年间，由于大气污染，到达地表的太阳光越来越少.

这份提交给美、加两国地质学会联合会议的报告指出，与20世纪50年代相比，到达地表的太阳光平均减少了10%。这一结论的依据，是设在全球各地的数百个传感装置所做的记录。美国航空航天局戈达德研究中心主任詹姆斯·汉森博士说，人们早已发现这一现象，但至今仍无人知道其确切程度。总体而言，阳光减少情况各地不同，一些地方还比较严重。大气污染以两种方式影响日照。一是污染物颗粒把阳光反射回宇宙空间；二是由于气候变化，空气中云雾量增加，从而阻挡阳光到达地表。不过，任何事物都有两面性。阳光减少的有利面在于，它在一定程度上减缓了全球气候升温的速率。科学家就此预测，冬季温室效应可能不会很快出现…………地球在哭泣，花儿再落泪，小草在悲伤……而我们在快快乐了地欢笑，没有感觉地球的危机！伸出我们的援助之手吧！全世界的人民伸出你们的援助之手吧！我们的家已经生病了！地球养育过我们，现在我们要来帮助自己的母亲了。让我们捡起一片小小的做起，为我的地球做出自己的一片贡献。我相信，我们坚持不懈，我们的母亲会越来越美丽！

被污染的河作文篇6

二十一世纪,随着科学技术的发展,，人们建造了越来越多的工，,很多工厂都往河里排放污水、废渣等有害物质，污染了一条又一条的清澈的小河，有些人还随意地将生活垃圾扔进河里，导致河水肮脏不堪，水质遭到严重破坏。大量的含有化学物品和有毒物质的黑水以不可阻挡的势头滔滔不绝地涌进每条小溪，每条河、湖，直到流进大海。

假如所有的水都被污染了，会导致整个世界各地严重的自然灾害。干旱这个自然界的恶魔，将会控制整个世界。大批的人和动物会因缺水而亡，可怜的鱼儿被毒死，大批大批的浮在水面上，挤挤挨挨地覆盖了清澈的湖面，发出令人呕吐的`恶臭。陆地上的动物因找不到干净的水源，大批地渴死饿死；鸟儿们也无可奈何，渴得全身无力，头昏眼花，飞着飞着就像石头一样砸下来，落在地上；植物们不再像以往那样蓊郁苍翠，青翠欲滴，失去了雨水的滋润，它们暗淡枯黄，变了颜色，不久就会秋天的落叶那样，落得一树的凄凉。它们都是无辜的，是因为人们过度的贪婪，愚蠢的举动害了它们！

它们哭诉，哀求：给我们点水喝！可转而又自我安慰：即便人们给了水，我们能喝吗？还不是和没水喝一样的下场！人类自己都没可以饮用的干净水了，哪还顾得上我们？

地球姑娘不再像以前那样美丽了，皮肤干裂，头发枯黄，面目无光，肮脏丑陋，她向自己的父亲——太阳诉说：“都是人类把我弄成了这个样子，让他们离开这个地球！”话说到这里，她嚎啕大哭起来。

让我们自己好好想想吧！污染水源不就是一种自杀行为吗？假如所有的水都被污染了，是多么可怕，水是生命之源，我们应当共同保护水源的洁净和卫生，让我们行动起来，为了我们自己，为了我们赖以生存的

地球，为了人类的朋友——所有的动物和植物！

假如世界上的水都被污染了，那么世界上最后一滴水将是人的眼泪！

被污染的河作文篇7

春天的早晨，海鸥妈妈走到小海鸥的床前说：“快醒醒，今天天气特别好，我带你去海上找吃的。”小海鸥一听非常高兴，立即起床跟着它的妈妈飞向大海。

那天，晴空万里、风平浪静，它们不停地在海面上飞来飞去，寻找海里的食物。远方有一艘大油轮自西向东的开了过来，越走越近。这时，油轮上发出“轰”的一声巨响，接着油轮里的石油很快的流了出来，它们立即飞回到岸上去。

海水被污染了，海鸥妈妈很着急，它对小海鸥说：“油轮里流出来的石油漂浮在海面上，海里的鱼虾不能在这里生存下去了，我们也不能再在这里捕食了。”小海鸥忙问：“那我们以后可怎么生活呀?”接着就大哭起来。海鸥妈妈一看，耐心地说：“别怕，现在我们最重要的任务就是报警，请海上清洁队赶快来清除海上的污染。”小海鸥一听高兴地跳了起来，说：“太好啦!我现在就去打报警电话。”

小海鸥急忙跑回家里，拿起电话按了紧急呼救铃，电话里有人说：“我是海上清洁队，是谁打来的电话?”小海鸥回答说：“叔叔，我是东海岸的小海鸥，我们家门前的.大海里，有一艘巨型油轮触焦了，许多、许多的石油都流到了大海里”。没等小海鸥说完，海上清洁队就说：“我们马上出发，去你们那里救援。”

小海鸥走出家门，跑到妈妈跟前大声地说：“有救了，海上清洁队马上就来，帮我们清除海水里的石油，这样我们可以在这里继续生活下去了。”海鸥妈妈连忙夸奖了小海鸥，说他长大了、懂事了，独立生活能力也一天比一天的多了。

被污染的河作文篇8

as we all know, pollution is harmful to living beings. there are many different types of pollutions in this world. for instance, water pollution, air pollution, noise pollution and so on. water pollution cause many kinds of disease that have negative effects on human beings, sometimes the diseases will take people’s life away. dirty air will increase the rate of getting lung cancer. while the noise pollution will cause insomnia. people’s health condition will be damaged.

in my humble opinion, people should take measures to control the pollution. recently, not only the government, but also individual has taken part in the action of protecting the environment. this is a good sign. rivers are being cleaned, air is purified, and the people come to realize that the importance of protecting the environment.

however, this is not enough, the problems are still exist. not all of them have been solved. some factories are still pouring dirty water into the rivers or give off the toxic gas into the sky. we should know that protecting the environment needs everybody’s effort.

我们都知道，污染对生物有很大危害。在这个世界上，有许多不同类型的污染。例如：水污染，空气污染，噪音污染等等。水污染会使人们生病，甚至死亡。脏空气会使患肺癌的几率上升。而噪音污染会让人失眠。人们的健康水平会下降。

在我看来，人们应该采取措施去保护环境。最近，不仅仅是政府部门，个人也参与到环保中去。这是个好现象。河流干净了，空气清新了，人们也意识到环保的重要性。

然而，这些还远远不够。问题依旧存在。不是所有的问题都得到了解决。一些工厂依旧往河流里面排放污水，向天空排放有毒气体。我们应该谨记环境保护需要每个人的努力。
