城市环境变化英语作文（精彩20篇）

We cant live without water, but now the water was polluted. It is the biggest problem. It influences our daily life. So we should find a way to solve this problem. Water is important resources. In our daily life, we often leave the tap on after cleaning hands. Sometimes we often drop litter in the river. So the water was polluted by us. I think we could use a bottle of water two or three times. We have to turn off the tap after cleaning hands.

Lets try to form a good habit and save things around us. Lets do it from now on!

Water is very important to us. We cant live without water. But the drinking water is less and less. Because we waste a lot of water in our daily life. And some of us often throw rubbish into the rivers. So the rivers are polluted seriously.

Its our duty to save water, we must do something to save water. For example, we shouldnt pour waste water into the rivers and we should pick up litter around us.

If we dont save water, the last drop of water will be our tear.

Fish cant live without water. Plants cant live without water. People cant live without water, either. As you can see, the water is very important to us. But now drinking water is less and less. The water was polluted seriously.

So we would act quickly in order to save the water, But what must we do now? I think we can plant trees, clean the banks of the river, water the plants by using used water. Turn off the shower while we are washing hair. And we shouldnt drop litter into the river and so on.

Its our duty to try our best to protect and save water. And dont forget that if we dont save water, the last drop of water will be our tear.;

If we dont save water, the last drop of water will be our tear. What a frightful announcement!

Water is very important for people, animals and plants. Water is needed to many things in daily life, like taking a shower, drinking, washing clothes, making meals and so on. We cant live without water. But now water has become less and less because people waste water and pollute water. If we continue to do things like this, we shall destroy ourselves. So we should take action to improve the environment quickly. We shouldnt throw rubbish into the rivers. We should pay attention to environmental protection. We can use less water when we wash something. In a word, we should save water.

没有水我们无法生存,但是现在水被污染了。这是最大的问题。它影响我们的日常生活中。所以我们应该找到一个方法来解决这个问题。水是重要的资源。在我们的日常生活中,我们经常离开水龙头清洗后的手。有时我们经常在河里乱扔垃圾。所以我们的水被污染了。我认为我们可以用一瓶水两到三次。我们必须关掉水龙头后清洗双手。

让我们试着养成良好的习惯,节约我们周围的事情。让我们从现在开始吧!

水对我们是非常重要的。我们没有水是无法生存的。但是,饮用水越来越少。因为我们浪费大量的水在我们的日常生活中。和我们中的一些人经常把垃圾扔进河流。因此,河流污染严重。

节约用水是我们的责任,我们必须做些事情来节约用水。例如,我们不应该把废水倒进河流和周围我们应该捡起垃圾。

如果我们不节约用水,最后一滴水将是我们的眼泪。

鱼没有水是无法生存的。植物没有水是无法生存的。人没有水是无法生存的。正如您可以看到的,水对我们是非常重要的。但是现在饮用水越来越少。水被污染严重。

所以我们将迅速行动,以拯救水,但是现在我们必须做些什么?我认为我们可以植树,干净的河岸,通过用水浇灌植物。关掉淋浴当我们洗头发。我们不应该乱扔垃圾到河里,等等。

这是我们的职责尽力保护和节约用水。别忘了,如果我们不节约用水,最后一滴水将是我们的眼泪。

如果我们不节约用水,最后一滴水将是我们的眼泪。多么可怕的消息!

水对人们是非常重要的,动物和植物。水是需要很多东西在日常生活中,如洗澡、喝,洗衣服,做饭等等。我们没有水是无法生存的。但是现在变得越来越少,因为人们浪费水,污染水。如果我们继续这样做,我们将毁灭我们自己。所以我们应该迅速采取行动来改善环境。我们不应该把垃圾扔进河流。我们应该注意环境保护。我们可以用更少的水当我们洗东西。总之,我们应该节约用水。

The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.

Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that cant be replaced. Too much fishing may harm fish populations to the point where they cant recover. We are too careless in taking what we want without giving anything back.

There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners cant keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.

With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If were not careful, we can harm our planet beyond repair.

People need to respect the Earth and try to preserve it. If we dont, what kind of future will we have?

Tourism is becoming increasingly important to many countries but it also has its disadvantages.What are some of the problems of tourism?

First of all,tourism can ruin the environment.Another aspect is cultural,as sometimes foreigners show no respect for national traditions.In addition,it causes the price of everything rising.

In a word,tourism is very important,there are a lot of advantages about it,but we also should remember that there are always two sides of everything,but I believe the advantages and disadvantages of tourism can be in balance if we all become more attentive to each other and the world around us.

I believe the school environment protection are important because students need a quiet and pollution-free environment to study. What we need to do in order to maintain our clean and neat environment to our students? First, we will need to have giant garbage can around each corner. Second, we will need to have school policies regarding littering and spits on the ground, where students and teachers would be fine if they violated the school policies. Third, we also will need to have garbage cans in classrooms, school main entrance, back door, parking lots, basketball court, ect. Last, we will need to announce the school policies, so the students and teachers will need to follow. By doing all this, we can promise the clean and neat environment for our current and future students.

时间在变，岁月在变，美丽的家乡徐州也在变。从一个淳朴没人知道的小地方，变成了一个繁荣昌盛，无人不知无人不晓的城市，这需要付出很大的努力。

走在一条条宽阔的马路上，让我不禁想起了我们家门口那条泥泞的小路。以前这条小路非常的窄，只能供行人通过，而且到了下雨天，这条小路便泥泞不堪，让人无法行走，现在经过政府的大力改造，这条泥泞的小路已经变成了平坦的水泥路，人们再也不为出行发愁了。

现在随着科学技术的发展，人们出行再也不成问题了。拥有私家车简直是家常便饭，以前的城市街道上交通工具不过是马车，板车，能拥有一辆自行车都算是“土豪”。人们以前居住的房子大都是平房，瓦房，不防风也不防雨，而现在呢？高楼大厦越来越多，人们住的也越来越舒适，平房，瓦房也变的越来越少，甚至没有了，这难道不是徐州的变化吗？

城市的居住环境变了，人们的心情也随之改变。看，满大街的人们穿着五彩缤纷，款式新颖的服装，人们以前的衣服颜色只有黑色蓝色，样式也不好看，这不更能体现人们生活水平的提高吗！

原来大街上交通秩序非常乱，交警叔叔不仅要指挥交通，还要查处违规车辆，人们认为耽误自己的时间，就不顾生命的安全，乱闯红灯，横穿马路，导致道路发生堵塞，事故。而现在，人们不仅不横穿马路，乱闯红灯，而且看到违反交通秩序的还能主动制止，既减轻了警察叔叔的工作强度，也为家乡徐州增添了一道靓丽的风景线。

徐州的变化可真大啊！我们要保护这赖以生存的城市，保护这美好的环境，让我们在这个“大家庭”中健康成长。

The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly.

Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people.

When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health.

The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air.

Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases.

Nowadays more and more people realize it`s necessary and important to protect the environment. Alsothere are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition there are a few factories often cutting down the trees discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harderso we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

【参考译文】

如今，越来越多的人认识到环境保护的必要和重要性。同时，有些人整天都不注意卫生，而且他们不能停止乱扔垃圾或者随意，随地吐痰。此外，还有一些工厂经常砍伐树木，化学品和污水排放等。并导致像温室效应问题很多。如果他们现在这样做，我们的生活会越来越困难，所以我们必须阻止他们。阻止他们，我们可以贴公益广告，告诉他们破坏环境的危害。所以我们可以从现在开始做一个美好的生活。

My home town is in the center of Xuzhou which was a quiet and beautiful place. In the past, there were many animals. They were lovely and nice. The air was fresh and there were many birds fly in the sky.

我的家乡在徐州，是一个安静而美丽的地方中心。在过去，有许多动物。他们是可爱的，漂亮的。空气清新，有许多鸟在天空飞翔。

Over the past years, it has changed a lot. At the present, it becomes a modern town and develops a lot. Now, the people in Xuzhou are richer than before, so most of people go to work by bus or by underground. Sometimes, they also drive their private cars to work. Many people sell out their old houses and move into new flats.

过去的那些年，它已经发生了很大的变化。现在，它已经成为一个现代化城市，也得到了很大的发展。现在徐州的人都比以前富有，所以大多数人都是乘巴士或地铁去工作的。有时候，他们也开私家车去上班。很多人卖了他们的老房子，然后搬进新公寓。

In some ways, the development has brought some good things, but it has also causes much environment pollution. I think we should take action to reduce the pollution.

在某些方面，发展带来了好处，但是也带来了环境污染。我认为我们应该采取措施来减少污染。

作文一：家乡的环境

一转眼，四年过去了，我的家乡变化可大了！瞧！家乡就像一个美丽的大森林街道上干干净净，没有任何灰尘，绿树成阴，鲜花盛开，我们生活在绿色的世界里。

看看这样的家乡再看看四年以前的家乡。四年前我的家乡树木很少，刮大风时，尘土飞扬五颜六色的塑料袋也随风飘舞。空气糟透了。

那时人们不爱护身边的环境。就说我们家吧！我家的门口有条河，河里养了许多金鱼。可人们总把水果皮、树枝，包装纸扔进水里。时间一长河水都变黑了，鱼儿都死了。这都是人们不爱护环境造成的。

你看，如今我们在这么美丽的环境生活，多么幸福啊！我们要把环境保护到底，让家乡永远这么美丽！

几年后家乡的环境

作文二：家乡的环境变化

日月如梭，时间像飞箭，转眼间暑假又溜走了。假期中令我感受最深的是一家人一起回家乡。这件事仿佛就发生在昨天。

回到家乡，突然眼前一亮。还记得前几年回家乡时，我们走的路还是坑坑洼洼的泥路，下雨时泥土黏着鞋子，村民们走路个个都是左闪右避，以免踩到那大大小小的水坑。如今泥路变成了现在的水泥路，平滑而宽大好走了许多。以前每当夜幕渐临时，房屋门外一片漆黑，伸手不见五指。如果要外出都必须人手一盏电筒才能看清楚路面，如今路的两旁各安装了几盏路灯，给村民们带来了极大的方便。看！家家户户都盖上了新房子，就连外婆家也盖上了几层的楼房。“啊！家乡这几年的变化可真大。”我不禁感叹道。

朝远处看了看，啊！就连农民伯伯们也用上了新技术——用收割机来收割稻谷。“看来农村生活一点也不差过城市！”我不由自主地惊叹道。

村尾背靠着一座座连绵起伏的山头，青翠欲滴的。房屋的旁边是一亩一亩的稻田。夏天，正是稻谷成熟的第一季，也是农民伯伯忙于收获的季节。看！谷穗脱下了绿色的衣裳，换上了金色的服装。在微风的吹拂下，那一大片金灿灿的稻谷如同阵阵浪涛滚滚不息。夏日的夕阳在山峦起伏的青山中徐徐落下，加上黄澄澄的稻田与家家户户的楼房相映，成了一幅优美的油画图。我不得不再惊叹道：“家乡变化真大啊！”

区区的这几年时间里，家乡竟发生了如此翻天覆地的大变化。家乡不仅变得更富裕而且变得更美丽了。

望着变化如此之大的家乡，我感慨的大喊一声：“家乡，我爱您！”

几年后家乡的环境

作文三：家乡的环境变了

咦！以前的泥巴路变成了干净的马路。呀！以前的小矮房变成了高大的楼房。可是……现在的环境却……唉！

我的家乡在安徽蚌埠，现在家乡的变化很大，但是环境却大大不如以前了，现在就让我们去看看吧！

现在，随着科技的发达，家乡都盖起了楼房，生活有了大大的提升，这本来是件好事。可是，楼房盖起来了，工厂也随着增加了起来，工厂里排出的污水污染了小河，以前活泼乱跳的小鱼，现在都成了死鱼。绿化少了。以前，这里是一片又一片绿茵茵的草地，我们总爱在这儿放风筝、做游戏，笑嘻嘻的，跑累了，就躺在上面，数着白云，看着晚霞，和星星说晚安……可是，它们不见了。草地没了，水泥却覆盖在上面，人们生活虽然方便了，但是脸上的笑容少了。没有了玩耍的地方，大家都不喜欢出来玩了，都喜欢宅在家中。以前，这里的空气清新，连家家户户的饭菜香都能闻得到，现在呢，都没有了。香味全都被那难闻的烟雾吓走了。以前，夏天里总有着许多知了唱着“交响曲”，但现在夏天只能听到一两只知了的叫声。

人们啊！你们知道吗？你们的家乡在哭泣，你们的母亲在哭泣呀！

几年后家乡的环境

作文四：几年后的家乡环境

傍晚，我梦见时光老人把我带到了几年后的家乡。

大街上，人们开的都是太阳能汽车，不会排出废气，排出的居然是新鲜的空气。地上没有一点垃圾，原来人们发明了“清除垃圾机器”啊！所以地上干干净净。“清除垃圾机器人”还有语言功能，比如，你故意向他面前扔一个垃圾，它就会说∶“请把垃圾扔到垃圾桶里去。”

村里的树木长得很茂密，地上还有一朵朵野花，五颜六色的，美丽极了。还有许多树木，没有一棵树是枯死的，因为，发明家发明了一台叫“清理枯树机器”只要它吸进一棵枯死的树，它就会吐出精美的木材。

我又来到了小河边，河里的水清澈见底，连河里的小鱼都能看见，而且小河很平静，连一点声音都没有，河水碧绿，河底没有杂物，我问一位老渔翁，老渔翁说人们早已发明了“垃圾处理袋了”。“垃圾处理袋”的用处就是，只要河里有垃圾，它就会把垃圾处理掉。

空气一下子变得新鲜了，这就是“转换空气机”的用处，它可以把天空中的废气吸进去，放出新鲜的空气，不会让我们吸废气，天也变得更蓝了。

妈妈把我从床上叫起来，啊，原来这是一场梦，我好想把梦变成现实。

几年后家乡的环境作文五：几年后家乡的环境

一天晚上，我见到了我的家乡。

我来到大街上，空气很清新。大街一尘不染，这时我看见一个叔叔刚吃完香蕉就把香蕉皮扔在了地上。刮来一阵风，我一看是一个机器人。机器人用长长的机械手把香蕉皮给扔进了垃圾桶里。就想来时一样，一阵风刮走了。我看见大街上开汽车的人都用太阳能汽车。

我来到小溪边，看见小溪清澈见底。能看见溪底已经发黑的落叶、溪底的石头的颜色和在溪里活蹦乱跳的小鱼。向我走来了一位老人，我问他为什么小溪里那么清澈？他告诉我因为人们发明了一种机器人，他看见小溪里有垃圾就会把垃圾扔进垃圾桶里。

我来到山上，看见那里树木茂盛。这时来了一群人，身体强壮的人背着一棵棵树，有的拿着水壶，有的拿着肥料。他们告诉我只要一种树，就会有水和电了。

我睁开眼睛，发现那一切都是梦。

Now, our side of the car constant more up, the environment also increasingly worse!

That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do.

For example, we can go to school by bike or walk, it can exercise.

If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment.

现在，我们身边的汽车不断的多了起来，环境也越来越糟糕!以至于我们周围的空气有很多有害物质。所以，我们要苏身边的小事做起。比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。有时间的话可以少用电梯，多爬楼梯。我们不仅能锻炼身体,也能保护我们的环境。

我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。以下是小编给大家整理的形势与政策论文：城市水环境的问题探讨的内容，欢迎大家查看。

摘要: 随着经济快速发展，城市生态形势压力也与日俱增，水环境问题已成为制约社会发展的大问题，环保基础设施建设严重落后，城市生活污染物未得到有效控制，工业污染源未得到严格治理，农业污染日益突出，部分河段水质受污染严重，河水发黑发臭，完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词：城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分，城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响，我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失，造成了城市生态环境、水环境的进一步恶化。针对这样的情况，我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发，恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型，由于城市人员密集、工业化生产程度高，所以，城市用水需要较高的质量、较大的供水量、稳定的供给，这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高，所以，单纯依靠城市区域的供给和开采往往难于满足城市发展的需要，因此，大众城市往往需要从城区周边或外地调水来满足城市的用水需要，“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方，城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中，在日积月累的大量污染的影响下，城市水环境受到了严重破坏，并且这一现象有蔓延和恶化的趋势，造成水环境的脆弱和生态的破坏，影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个，一是，城市生产和生活中大量污染源渗入地下，造成对地下水资源和水环境的破坏;二是，城市地表硬化导致城市地面下渗量的减少，在大量开采地下水的同时，没有必要的补充，出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本，科学发展

把维护广大人民群众的根本利益作为第一点，把群众最关心、最直接和现实的水环境保护问题为重点，转变发展观念，重视生态文明建设，加快建设资源节约和环境友好社会，走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品，水环境治理应突出重点，优先保护饮用水源，确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩，把COD削减量考核指标纳入到区县水环境治理目标体系中，明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标，即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金，对节能减排效果明显，有一定经济基础，技术条件成熟，符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集，污染来源复杂。为此，河道治理将坚持“先截污、后清淤、先治理、后换水”的原则，周密排查河道沿线污染来源，大力实施清淤、截污、生态护坡、河岸绿化等措施，加强河道水体自净和生态修复功能;在突出截污治理的同时，各区县还将坚持污水处理厂、配套管网同步建设，大力提升现有污水处理厂运行负荷率，妥善解决污水出路，切实提高河道水环境质量。

5、加强协作，落实责任

市水务局于去年成立了河道水环境考核办公室，将清水工程已治理河道纳入考核范围，各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制，有效巩固水环境治理成果。此外，目前市政府已正式批准本市河道水环境实施“河长制”管理意见，即将公布全市主要河道“河长”名单，构建完善的河道水环境管理长效机制，为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述，我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。

There is no doubting the great benefits which scientific advances have brought us 。 Yet we have become increasingly aware that some technologies’ developing brings unexpected and harmful side effects 。

A number of factories spring up like mushrooms ，exhausting much waste gas ， which leads to the greenhouse effect and air pollutions 。 Plentiful trees are cut down that causes the lands to change into the deserts 。 At the same time ， varieties of species are gradually extincting 。 These phenomenons give us clear warnings of the dangers of failing to live harmony with nature 。

We ought to set up a profound mind to protect our environment 。 For the governments ，they should make detail laws and policies to observe the behaviors of destroying the environment 。 Factories should exhaust polluted water or gas after dealing with rather than merely pursue the economic interests 。 Planting as more as possible trees ， in case of the water and soil erosion 。 For farmers ， they must reduce spraying the insecticides 。 We also must make less use of plastic materials and one—off products 。 In addition ， we wouldn’t throw the rubbish anywhere 。 Thus ， we at least can maintain our environment in a good state 。 However ， that’s not enough 。 We are supposed to work harder to protect our environment 。

[英语作文怎样做到保护环境

Stepping into the new century, environment pollution has become more serious than ever since. There are different kinds of pollution. Such as, water pollution, air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. Where all these pollution comes from? To a large extend, the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel, people cut down trees and dig more corals. But the growing needs for energy are hardly to meet. Countless private cars on the street, the gas stations are short of gasoline, even the government has raise the price so many times in order to control the needs of gasoline, but it’s still not working. Overusing the natural resources has already affected the ecological balance. However, the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.

The government should put forward some more strict laws to prevent the environment from being further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again. Only in this way, our earth could be a better place to live in.

进入新世界以来，环境污染比任何时候都要严峻。有各式各样的污染：水污染，空气污染，噪音污染等等。看起来我们活着一个四周都是污染源的星球。那么，这些污染是从何而来的呢?在很大程度上，环境被破坏就是我们为快速的经济增长和人口增加所付出的惨烈代价。为了得到更多的能源，人们砍伐树木，挖更多的煤矿，但是还是难以维持日益增长的需求。不计其数的私家车充斥着公路，加油站的汽油严重短缺，政府多次上调油价也未能阻止私家车对汽油的需求。自然资源的过度利用已经影响到了生态平衡。然而，工厂依旧向外排放有毒气体，把工业废水倒入河里。人们依旧缺乏保护环境的意识。我认为人们应该做些事情了。

政府应该施行一些更为严格的法律来防止环境被进一步的破坏掉。他们应该让人们了解到保护环境的重要性。我们要在保持经济发展和环境保护中找到平衡点。在沙漠中植树造林，停止砍伐森林。禁止工厂往河流里直接排放废水。鼓励人们用交通工具上班。政府和普通民众都应该携手保护环境，让我们的家园变得干净整洁。只有这样，我们的地球才能更适合人类居住。

When freshmen enter the university at the first time they have to deal with all kinds of affairs independently.Whether a new student can understand and become familiar with the environment of the campus rapidly will determine whether he can live and study freely.

You want to know sthe changes about my hometown. You know, great changes have taken place since 60 years ago.

In the past, the living conditions were very poor. There were not many buses or cars, and the roads were narrow. Usually, a big family was crowed into a small, dark house. Most families couldn’t get enough food. The communications were simple and slow. People kept in touch with their friends and relatives far away mainly by letter or telegram.

Thanks to the government, our hometown has developed rapidly in recent years. The living conditions are much better and more comfortable. The roads are wide. Some people have their own cars. Most of the people have lived in big new houses. Quite a few adults have mobile phones. Because of many good policies, I think our lives will become better and better.

We human beings live on the earth, the earth has a lot of things we need to protect, but we dont care.

Now on, we should protect the environment, to defend our home together.

我们人类生活在地球上，地球上有许多东西需要我们保护，但是我们却没有在意。

有些人不珍惜地球赐予我们的一切，例如人们乱砍乱伐，大量使用一次性筷子和乱扔塑料袋，制造白色垃圾等已经给大自然带来了许多环境问题，严重影响了我们的生活。还有大气污染，酸雨和臭氧层等带来的危害都是大自然给人类带来的灾害，人们乱砍乱伐，乱扔塑料袋和使用一次性筷子等，这些就是人们不尊重大自然而造成的，没有自然，便没有人类。这是世界一大朴素的真理，人们只会一味的抢夺自然，征服自然，只会破坏生态系统，咎由自取，使人类濒于困境。切记，保护环境就等于保护我们自己生存的环境。

我们要保护这个脆弱的的地球，不要让茂密的森林，辽阔的草原和无边无际的海洋成为我们的回忆。

现在起，我们应该保护环境，一起捍卫我们的家园。

1972年6月5日-16日，“联合国人类环境会议”在瑞典的斯德哥尔摩召开，这是人类历史上第一次在全世界范围内召开的保护人类环境的会议，具有里程碑式的意义，是人类环境保护行动史上划时代的事件。会上，各国与会代表建议联合国大会将“联合国人类环境会议”开幕日——“6月5日”定为“世界环境日”。同年10月，第27届联合国大会接受并通过了这项建议。

“世界环境日”的意义在于提醒全世界的人们注意全球环境状况的变化，以及人类活动对环境已经造成的危害，要求联合国系统和世界各国政府在每年的这一天开展各种宣传、纪念活动，以强调保护和改善人类环境的重要性和迫切性。联合国环境规划署也将在每年的世界环境日选择一个成员国举行“世界环境日”纪念活动，发表《环境现状的年度报告书》，确定该年世界环境日的主题。在“世界环境日”的那天，各国政府和全世界的人们都要举行各种形式的纪念活动，宣传环境保护的重要性。呼吁全体地球公民为维护、改善人类环境而不懈地努力。

"World Environment Day" is to remind people to the attention of the whole world changes the state of the global environment and human activities on the environment, the harm has been caused, the United Nations system and governments around the world every year on this day to carry out a variety of promotional and commemorative activities, in order to emphasize the importance of protecting and improving the human environment and the urgent.

Protection of the Environment Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive. We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products arestill put into rivers. We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycie them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

Throughout the ages, the earth mother with the sweet milk fed numerous generations of descendants. The original she was decorated by the junior was very clear and moving. However, now human beings for their own interests, tortured her innocent and dark. Mankind has only one earth; and the earth is facing a severe environmental crisis. "Save the Earth" has become the strongest voice of the people of the world.

Humans are part of nature and are part of the world of life. Many lives constitute a coexistence and coexistence related to the reputation of large systems. Humans must treat nature, care for the environment, protect animals and plants, otherwise, will endanger their own survival.

Once upon a time, people have been cut off, so that the ecological balance of nature has been destroyed. Dune swallowed the vast expanse of fertile land, the flood washed away the lovely home, the natural revenge of human embarrassment dumb. Mei Shui River once said that there is no natural, there is no human, this is the world a simple truth. Blindly plunder nature, conquer nature, will only destroy the ecosystem, blame themselves, so that human beings on the verge of difficulties. This sentence is not bad, people do not give natural face, of course, naturally will not give people behind the road, 98 floods, dust storms in 2000, 08 earthquake, in fact, this is the nature of the warning issued to mankind. Environmental protection is not a new problem for us, and our government has long put forward clear governance objectives. As a real life in every ordinary people, although it is impossible to directly engage in environmental protection work, but we can start from small, start from me. We should establish environmental awareness and take practical action to implement environmental action. See the faucet in the toilet when the drip should be able to raise their hands. When the battery is used up after the collection should be collected instead of readily throw away. When shopping should consciously do not use ultra-thin plastic bags ... ... a small thing though very humble, but it shows how much we have a sense of environmental protection.

Cherish resources, protect the environment. Lets make this city more beautiful!

Remember, protect the earth is to protect yourself!
