Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

Cars and Air Pollution

Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly.

On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

随着人们生活水平的提高，人们越来越不重视保护环境，随地扔垃圾，随地吐痰。

每当我看到地上的垃圾，我就会感慨万千，保护环境，从我做起。就拿我家附近的一条小河来说吧，以前，河里的水十分清澈，像一块明亮的大镜子，可以清清楚楚地看到河底的许多石头;可以看到小鱼在河里自由自在在游来游去。经常有许多小朋友在河里嬉戏、玩水;大人们在河里洗菜，洗衣服。渐渐的，人们于是把垃圾扔到河里，污水排放到河里，使河水变得又臭又脏，再也不能清澈见底，变成了浑浊不清的垃圾箱。严重污染环境，严重危害了人们的身体健康。对，只有树立保护环境的观念，才有美好的明天。

星期天，我找来我的好朋友小好，每人拿一个塑料袋，把河边的垃圾一一捡光了，我们手里都是满满的一塑料袋，真是“满载而归”啊!即使我们把河边的垃圾捡光了，但是河里的垃圾是阻止不了，捞掉了还会有，怎么办好呢?最关键的还是唤起人们的环保意识，我们找来一块木板在板上大大地写上：请保护环境，从我做起。我们把它放在河边最显眼的地方，任务完成，我们高兴地回家了。

The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical,biological,and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.

Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies.Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day,mostly in developing countries.

Many people are not aware that water pollution is serious problem in almost all parts of the world,and not just in third world countries like some choose to believe.In fact many experts will tell you that reality is completely different than the common belief,and that actually water pollution problem is already out of control.

Water pollution problem is in most cases connected with the careless handling of chemical agents,toxins introduced into our water through industrial dumping,and farm runoff.All these factors make our water unsafe to drink.

My house have a garden downstairs, where flowers bloom all the year round, is the main place to neighbors leisure entertainment. The children often play there, I also liked to play there.

Homework today, I came to visit my good friends in the garden, flowers, they found flowers side there are a lot of rubbish. Think of "the teacher said to protect the environment is the responsibility of each one of us", I immediately ran over to pick up all the rubbish into the dustbin, at this moment, the other side of the garden came the cries of children: Peng Linqian, come and play! I cant help but stopped, the in the mind like two little quarrelling, pick up, afraid of see after children, said I was picking up litter. Dont pick up, let the garbage lying there quietly? Because of this problem, let me in a quandary. Pick up or not pick up? Ask mom and dad to say again!

Mom and dad is walking toward the side, and the father said, "of course it is important to environmental protection, you should start from around things, do not litter. If you see a garbage on the ground, should pick it up, so that you do to protect the environment." Mom said so.

Mom and dad gave me courage. Environmental protection is more important than face, they would say I am picking up litter and let them say! I dont care now. If a man pick up a garbage, more people will be able to pick up more junk. Earth must be the earth more than it is now clean and more beautiful.

Without hesitation, I run past, all the trash in the underground (bin) back to their home. Then, the people around to me to approval.

我家楼下有一个花园，那里一年四季都有鲜花盛开，是邻居们休闲娱乐的主要场所。小朋友们也经常在那里嬉戏，我也特别喜欢到那里玩。

今天做完作业，我又来到花园里看望我的那些好朋友——花，却发现花儿的身边有很多垃圾。想到老师说的"保护环境是我们每一个人应尽的责任"，我立刻跑过去准备把垃圾都捡起来送进垃圾箱，这时，花园的另一边传来小朋友的喊声：彭林茜，快来玩!我不禁停住了脚步，心里像有两个小人在吵架，捡，怕小朋友看见后，说我是捡垃圾的。不捡，就让垃圾静静的躺在那儿?就因为这个问题，让我左右为难。捡还是不捡?问问爸爸妈妈再说吧!

爸爸妈妈正好也朝这边走来，爸爸说："那当然是环保重要，你要从身边的小事做起，不要乱扔垃圾。如果看到地上有垃圾，当然应该捡起来，这样你就为保护环境做了贡献。"妈妈也这么说。

爸爸妈妈的话给了我勇气。环保比面子更重要，他们要说我是捡垃圾的就让他们去说吧!我现在不在乎了。要是一人捡一次垃圾，更多的人就能捡更多的垃圾。那时候的地球一定比现在的地球更干净，更美丽。

我毫不犹豫地跑过去，把地下的垃圾全部送回了他们的家(垃圾箱)。这时，周围的人们向我投来赞许的目光。

Protect Our Environment It is important to beal with the rubbish in cities. Our world was colorful,beautiful and full of life. But these years, people have built many factories along rivers. Many trees have been cut down. Many animals have lost their homes. Factories cause pollution. Rivers become polluted. As a student, you should do every things in your everyday life to protect them. First, stop wasting more water. Second, throw waste things into different dustbins. For example, waste paper should be throw into paper recyclable bins. Third, stop cutting down trees. Instead, plant more. Fourth, pick up garbage in the park or on the road when we are free. Last, call on more and more people to pay attention to contrlling pollution. In a word, everybody has his duty to protect the world.

We need to protect wild animals, because we protect wild animals, wild animals will be very friendly to us.

Like the swallow, swallow can help us to eat the pests in the field. If we human beings killed to catch them, they will eat mosquitoes that often to scratch faze us, let us better life? Without the swallow around us become many insect pests, these pests have great harm to our human!

I have an example. For example the frog, the frog can also help us to eat the pests in the field, can be said to be the police in the field. Once we kill them, not the frog, the pests in the field more and more, pest constantly eat vegetables, dont we will have a good harvest?

I have an example. Such as w, w is a doctor in the forest, it can help us to eat the pests in the tree, the tree back to health. We killed them, pests will be more and more trees, trees will slowly decrease. No trees on earth, floods, earthquakes.

My last an example. Such as owls, catch rats, the owl is good for us human beings, human is often hunt them. No owls, voles will increase. Rats ate the crops and vegetables is more, we human beings did not have a good harvest.

So, we need to protect more than animals. At the same time, we also need to protect other wild animals!

我们要保护野生动物，因为我们保护野生动物，野生动物对我们人类也会很友好。

比如说燕子，燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们，它们会吃掉那些常常来搔扰我们的蚊子，让我们更好地生活吗?没有了燕子，我们的周围变得很多害虫，这些害虫对我们人类有很大的坏处呀!

我还举个例子。比如说青蛙，青蛙也能帮我们吃田里的害虫，可以说是田里的警察。我们支捕杀他们，一旦没有了青蛙，田里的害虫越来越多，害虫不断地吃菜，难道我们会有美好的丰收吗?

我还举个例子。比如说啄木鸟，啄木鸟是森林中的医生，它可以帮我们吃掉树里的害虫，让树恢复健康。我们杀害它们，树木的害虫会越来越多，树木会慢慢地减少。地球上没有树，会发洪水、地震。

我最后举个例子。比如说猫头鹰，猫头鹰捉田鼠，是对我们人类有好处的，人类却常常捕猎它们。没有猫头鹰，田鼠会增加。田鼠吃的庄稼和菜就更多了，我们人类一样没有好的收成。

所以，我们要保护以上的动物。同时，我们还要保护其他的野生动物!

我们的祖国虽然资源、物产比较丰富。可是，你知道吗?光光这些都还不够，更重要的是要注重环保!

Although our motherland is rich in resources, products. But, you know? Only these are not enough, it is more important to pay attention to environmental protection!

我觉得，政府应该多多提倡环保，多多参与环保工作，为环保做贡献，组织好环保是最关键的。你们说，是吗?

I think, the government should take to promote environmental protection, actively participate in the environmental protection work, make a contribution to protecting the environment, organization of environmental protection is the key. You say, yes?

首先，应该告诉市民，要关注每一件环保的事，积极做环保工作，不要随手扔垃圾、看到垃圾要及时捡起。其次，要把废旧电池该扔哪的问题解决好，应该把这件事给做得更完善：在一些地方分放一些回收废旧电池的筒，每天都有专门负责的人去取。这样一来，不管是住在偏远地区，还是住在热闹的地方，都可以很方便的把废旧电池处理了，再也不会发生人们不知道废旧电池怎么处理，就把废旧电池扔进垃圾箱里的事了。最后，政府应该增加一个环保工作者的职务，让更多的人投身于环保工作当中!

First of all, should tell the people, pay attention to every green thing, to do environmental protection work, do not readily throw garbage, garbage to pick up see. Secondly, to throw the waste batteries which to solve the problem, should put this thing to do better in some places put some recycling waste batteries, cylindrical, every day there are responsible for people to get. In this way, whether it is to live in the remote areas, or in the bustling place, can be very convenient to the handling of used batteries, and it wont happen again and people dont know how to deal with the waste batteries, waste batteries thrown in the garbage again. Finally, the government should increase a environmental protection worker job, let more people involved in environmental protection work!

为了环保，行动起来吧!

To be environmentally friendly, action!

Everyone knows animals are our friends. So we should be friendly to them.

But some people kill the rare animals, such as pandas, golden monkeys and so on in order to get money.

It will cause these animals to disappear soon.

I think our government should punish those people severely who kill the rare animals.

It is our duty to protect the endangered animals.

我们渴望干净的地球，渴望健康的地球，渴望环保的家园，渴望绿色，健康，卫生的社区……让我们用爱心去关注环境的变化，用热情去传播环保的观念，用行动肩负起环保的重任。从我做起，从现在做起，从身边的点滴小事做起，把环保承诺变为实际行动。

Today, Dameisha took me to see the sea, because I have never seen the sea. I was thinking of the sea all the way. I saw on TV the sea is very beautiful, I feel that the sea should be like this: blue water, spray gently lying in the arms of the sea. On the beach there grows many palm beach, lying quietly in many shells, conch. A few crabs to climb. Should be against the background of blue sky, the sky the sun, seagulls flying, this beautiful picture of you! What an intoxicated! I feel relaxed and happy.

Can be when I saw the sea of a moment, I am disappointed, the mood suddenly changed. Because my eyes of the sea is dark, is muddy, is not angry, is not confident. Some just inferiority. I know that the sea is not so, but people are polluting into this.

Now, human beings in order to live, a large number of cutting trees, cut and not planted, how many of the previous tropical rain forest, now is flat, how many trees, now replaced by high-rise buildings. Factory emissions, air pollution, and no trees to release fresh air. And plant emissions of toxic wastewater, so that water in the small fish, shrimp have been poisoned, and the river afloat smelly fish dead bodies and garbage, all this is how terrible ah!

Lets go and embrace the nature! To protect nature! Let everything in the world be beautiful.

今天，大姨带我去大梅沙看大海，因为我从来没有见过大海。我一路上都在想大海的样子。我看见电视上的大海很漂亮，我觉得大海应该是这样的：碧蓝的海水，浪花轻轻的躺在大海的怀抱中。海滩上生长着许多的椰树，海边静静的躺着许多贝壳，海螺。几只螃蟹爬来爬去。映衬着的应该是蔚蓝的天空，天空上的一轮红日，海欧飞来飞去，这景象多美呀！多令人陶醉呀！我心情轻松愉快。

可当我才看见大海的一瞬间，我失望了，心情一下子变的沉重了。因为我眼前的大海是灰暗的，是浑浊的，是没有生气的，是没有自信的。有的只是自卑。我知道大海原来不是这样的，而是被人们污染成这样的。

现在，人类为了生活，大量砍伐树木，砍了又不栽，以前有多少热带雨林，现在是平地，以前多少树木，现在取而代之的是高楼大厦。工厂排放的废气，污染空气，又没有树木放出新鲜的空气。还有工厂排放出的有毒的废水，让水里的小鱼，小虾都被毒死了，河面上浮着发臭的鱼的尸体和垃圾，这一切又是多么的可怕呀！

让我们去拥抱大自然吧！去保护大自然吧！让世界上的一切都变得美好。

Recently, the problem of environmental pollution is getting more and more serious.

The air pollution, noise pollution and water pollution are found on the newspaper everywhere.

It is obvious that we should do something to protect our earth. Because we have only one home.

We should try our best not to pollute the environment and appeal the people around us make their effort to protect our unique home.

近年来，环境污染问题越来越严重。

空气污染，噪音污染,水污染是在报纸上随处可见。

很明显，我们应该做些什么来保护我们的地球。因为我们只有一个家。

我们要尽量不污染环境，还要呼吁我们周围的人努力来保护我们唯一的家园。

Today I am very glad here to share my opinionsabout the protection of environment.

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

Thank you for listening！

环境保护

Nowadays, peoples life has changed a lot with the development of modern technology and economy, which has put lots of negative effects on the environment.

Why this? Because, firstly, some factories are pouring wastes into rivers, lakes, seas and so forth; secondly, because of human activities, a great number of plants and animals are losing their lives; thirdly, using modern machines and chemicals is bad for the environment. Besides these, there are a lot of human activities which have done or are doing harm to our surroundings.

For this, I think, first, our government should make drastic measures to regulate human activities; second, we human beings should take pains-taking work to stop ourselves destroying the environment and try our best to protect our living space more.

[英语作文：环境保护

Environmental pollution can cause direct damage and impact to ecosystems, such as desertification and forest damage, which can also cause indirect hazards to ecosystems and human societies. Sometimes the harm of this indirect environmental effect is greater than the direct hazard caused by it, It is more difficult to eliminate. For example, the greenhouse effect, acid rain, and ozone depletion are the environmental effects derived from atmospheric pollution. This environmental effect derived from environmental pollution is lagging behind, often at the time of the occurrence of pollution is not easy to be perceived or expected, but in the event of environmental pollution has been developed to a very serious point. Of course, the most direct and most environmentally conscious consequence of environmental pollution is the decline in the quality of the human environment, affecting human quality of life, physical health and productive activities. Such as the citys air pollution caused by air pollution, peoples morbidity and so on; water pollution so that the deterioration of water quality, drinking water quality generally decline, threatening human health. Serious pollution incidents not only bring health problems, but also cause social problems. With the increase in pollution and peoples awareness of the environment, due to pollution caused by population disputes and conflicts increased year by year.

Let us all love nature, love the earth, hand in hand, shoulder to shoulder, heart to cast a green embankment, to defend the resources, to defend the environment, to defend the earth, to defend our beautiful home now!

环境污染会给生态系统造成直接的破坏和影响，如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害，有时这种间接的环境效应的危害比当时造成的直接危害更大，也更难消除。例如，温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应。这种由环境污染衍生的环境效应具有滞后性，往往在污染发生的当时不易被察觉或预料到，然而一旦发生就表示环境污染已经发展到相当严重的地步。当然，环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降，影响人类的生活质量、身体健康和生产活动。例如城市的空气污染造成空气污浊，人们的发病率上升等等;水污染使水环境质量恶化，饮用水源的质量普遍下降，威胁人的身体健康等。严重的污染事件不仅带来健康问题，也造成社会问题。随着污染的加剧和人们环境意识的提高，由于污染引起的人群纠纷和冲突逐年增加。

让我们都来关爱自然，热爱地球吧，手挽手、肩并肩、心连心地铸起一道绿色环保的大堤，捍卫资源、捍卫环境、捍卫地球、捍卫我们美好的家园吧!

Animals are peoples friends, we should protect them.

If there is no animal on earth, there would be no human. Animal is a most of the earths food chain, if animals disappeared, we human beings will be extinct. For example: the frog disappeared, there is no animal pests to catch paddy fields, crops will not grow, humans have no food; If there is no tiger, the rabbit will excess breeding, our food is likely to be a rabbit eat didnt; If there is no owls, mice will encroach on our territory...

The earth is a big family, not lack of anyone, without animals, we humans situation, we should all band together and protect small animals.

动物是人们的朋友，我们应该保护它们。

地球上如果没有动物，就没有人类。动物是这个地球生物链的一大部分，如果动物消失了，我们人类也会灭绝。例如：青蛙消失了，就没有动物去捉稻田的害虫，农作物也就无法生长，人类就没有食物;如果没有老虎，兔子就会超额繁殖，我们的粮食就可能会被兔子吃没了;如果没有猫头鹰，老鼠就会侵占我们的地盘……

地球是一个大家庭，缺谁都不行，如果没有动物，我们人类的处境可想而知，我们大家应该团结起来，保护小动物。

People often say: the construction of a modern city, first of all to ensure that the city should have a good ecological environment.

Every day in the morning to go to school, he always can see the ground clean; At noon after school, I always can clearly see garbage on the ground, and trash can next to the clean, dont these people dont know garbage into the trash can? No, they know, even kindergarten children know garbage to throw into the trash, how come they dont know? They litter is completely in order to save trouble, because they are at the moment of litter didnt thought that could damage the environment, there is no thought that could bring inconvenience to the cleaners. I wonder why, these people have no morality heart? If so, I ask them to stop littering, please them to protect the city, to protect our beautiful home.

Day, the once very blue, but because of air pollution from factories, make the blue of the sky becomes cloudy; Water was very clear, but because the effluent from the factory, once the bottom stream become colorful; Forest, once very lush, but due to the deforestation of people, make once lush forest into a desolate desert...

At our side, there are many "environmental small guards", of course, there are a lot of damage to the environment behavior; Environmental protection of people we need to encourage them to adhere to the environmental protection, destroy the people we need to tell them the benefits of protecting the environment and damage the environment.

I hope that people can do it later "protect the environment, everyone duty", and the ability to truly realize the importance of protecting the environment, and make everyone around him to do this, in this way, our earth will be able to more and more beautiful, more and more prosperous!

人们常说：建设一座现代化的城市，首先要保证这座城市要有良好的生态环境。

每天早上上学时，总是可以看到地面上干干净净的;中午放学的时候，我总是能清楚地看见地上的垃圾，而旁边的垃圾桶里却干干净净的，难道这些人不知道垃圾要丢到垃圾桶里吗?不，他们知道，连幼儿园的小朋友都知道垃圾要丢到垃圾桶里，他们怎么会不知道呢?他们乱丢垃圾完全是为了省事，因为他们在乱丢垃圾的那一刹那根本就没有想过这会破坏环境，根本就没有想过这会给清洁工带来不便。我很纳闷，这些人究竟还有没有公德心?如果有，我请他们不要再乱扔垃圾，请他们一起来保护这座城市，保护我们美丽的家园。

天，曾经很蓝，可是由于工厂排放的废气，使曾经湛蓝的天空变得浑浊不堪;水，曾经很清，可是由于工厂排放的污水，使曾经清澈见底的溪水变得花花绿绿;森林，曾经很茂盛，可是由于人们的过度砍伐，使曾经郁郁葱葱的森林变成了荒无人烟的沙漠……

在我们的身边，有许许多多的“环保小卫士”，当然，也有很多破坏环境的行为;环保的人需要我们去鼓励他们坚持环保，破坏的人需要我们去告诉他们保护环境的好处以及破坏环境的弊端。

我希望，以后人们能够做到“保护环境，人人有责”，并且能够真正地意识到保护环境的重要性，并且使身边的人都做到这一点，这样，我们的地球就能够越来越美好，越来越富强!
