有关于保护水资源的英语作文最新20篇

As is known to all, waste on campus has become a more and more serious problem. We can easily see many students dump a lot of food in the garbage can. Some students spend thousands of yuan buying fashionable clothes and so on.

The negative effects of waste can be shown in the following aspects. In the first place, it makes some students dependent on their parents for money, which is harmful to their development.

If they don’t learn to support themselves, they will be “useless people” when they graduate. In the second place, it is not easy for our parents to arrange for our schooling. Last but not the least important, there is no denying the fact that our country is still poor. There are many people who cannot go to university and many poor people still need our help.

As far as I am concerned, I should set a good example to reduce waste on campus. First of all, I will refrain from wasting anything, from food to stationery. What’s more, I’m determined to call on more schoolmates to fight against waste. Only through these measures can we hope to reduce waste on campus.

Although the world develops much faster and better, the resources on the earth get fewer and fewer. In order to protect them,something must be done.

尽管世界发展得更快，更好，地球上的资源越来越少。为了保护它们，必须做些什么。

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.

Presently, the world is faced with serious water problems. But these problems witt become more intense and more complex in the future. Our increasing population witt tremendously increase urban waters, primarily sewage. On the other hand, increasing demands for water witt decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce large volumes of liquid wastes. Many of thesewitt contain chemicals that are poisonous. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever increasing quantities of agriculture chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problems.

There are two ways by which these pollution problems can be lessened. The first relates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes to permit the reuse to the water or best reduce pollution upon final disposal. The second approach is to develop an economic use for all or part of the wastes. Farm manure is spread in fields as a nutrient. Wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Liquid wastes from other processing plants may also be used as a supplemental source of water. Only by doing these promptly now can we expect to solve the serious water problems in the future.

Recently, it is very popular to live a low-carbon life.Living a low-carbon life is ofgreat importance to every one. First of all, it can protect the environment to a great extent. Second, it can save the limited natural resources and energy, and will leave a better world for our offspring.Third, it is a healthy lifestyle and will help mould a harmonious social atmosphere.

Therefore, how to create a low-carbon life is necessary for us to consider. To begin with, we should save the energy, such as the electricity, water and domestic gas. Second, when we go out we can walk or ride a bike instead of by car. Third, we should not use the plastic bags which are hard to break down. If so, we can live a low-carbon life and gain the happiness of it.

Important to save water

Water is a kind of liquid. It has no taste or smell. It is transparent, too. Water is useful and is important to us. Why? For example, we use water to water the plants. We use water to wash our face or to have a bath. We drink water or we will die…Water is also very important for China. There are 2.8 hundred millions of steres of water in China, but everyone can only use 2300 steres. It is only twenty–five per sent in the world.

Not too long ago, there was a man called Jacques Cousteau. He loved the beautiful colors, and the beautiful fish in the sea. However, when he returned some years later, the colorful coral reefs were dead and grey because the factory near the sea poured waste water into the sea. Jacques Cousteau decided to tell people how important it was to save the environment under the sea. He started the“ Cousteau Society ” to help protect life in the sea. Now there are over 30000 members all over the world. Since water covers most of the earth, Cousteau knew that we should keep the sea clean. We should not litter the sea, and should clean up the dirty parts. As water is very important to our environment, he encouraged everyone to take part in protecting our lakes, rivers, sea and ocean.

There are still a few people who are not protecting the water now in the world. For example, some factories pour waste things into the rivers, lakes or into the sea near by. The water there has become very dirty and we can’t use them at all. Although there are seventy–five per sent of water in the world, we can only use fresh water, that there is only a little. So we should use little water when we need to use it. For example, I do not use too much water when I am washing my face or having a bath… It is important for us to keep the water clean. You may ask yourself, have I ever poured or thrown dirty things into the water? If your answer is “No”, that means you have already helped to protect the environment. It is our duty to protect the environment. You may ask yourself again, have I ever helped to clean up the water? If your answer is “Yes”, that means that you have already done something useful to improve the water. If we use up all the water, it is difficult for us to get it from anywhere, including the universe. It is terrible to think that people are too thirsty to live! I believe, that if everyone helps to protect the water, the water must be protected. You do not want to “kill” your son or your grandson, do you? So now let us to protect the water! Please don’t let the last drop of water on the earth is we human’s tear!

Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States aloneare considered in danger.

动物是自然资源，人们已经浪费了整个历史。动物已为他们的皮毛和羽毛，食物而被杀，运动，因为他们在路上。成千上万种动物已从地球上永远地消失了。今天，数百人在危险中。对170种美国aloneare危险。

Why should people care? Because we need animals, and because once they are gone, there will never be any more.Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

人为什么要在乎?因为我们需要动物，因为它们一旦消失，就永远不会再出现。动物不仅仅是漂亮或有趣的。它们不仅仅是人类的食物来源。每一个动物在自然界的平衡有它的地方。毁灭某种动物会导致许多问题。例如，当农民杀死为数众多的鹰，他们谷物和粮食的商店被老鼠破坏。为什么?因为鹰吃鼠类，没有鹰控制它们的数量下降，鼠类就会迅速繁殖。

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

幸运的是，有些人正在努力帮助拯救动物。有些组织筹钱以便让人们了解这一问题。他们试图让政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法律禁止任何动物或杀害濒危名单。慢慢地，某些濒危动物的数目正在增长。

The animal is the friend of our human beings. We live in the same earth.

Animals and human beings can’t be separated from each other. But some animals

are getting less and less. So it’s necessary for us to protect animals,

especially wild animals. Some people kill wild animal because of money. It’s

illegal. Beside, because of the development of society, human needs more space

to live in, so we explore the forest. Animals have less space to live in. The

number of wild animals decreases year by year. It’s high time to take actions to

protect wild animals.

春天到了，青蛙又开始“呱呱”地唱歌了，我发现又有人在田野里开始捕捉青蛙了，使青蛙成为那些人的“盘餐中”，我感到非常痛心。

Spring has come, the frog began to "Gua Gua" to sing, I found someone in the field began to catch frogs, the frog became those who "tray", I feel very sad.

鲸是一种庞大的动物，它的身上全是宝。

日本人常常捕鲸，就把鲸当成世界上美味之一。日本人把鲸捕来，不就是吃就是做东西，现在鲸的数量越来越少，国家提出不要捕鲸，日本人就要捕鲸。日本人曾经捕获过440条小须鲸。还死活不放的把那些可怜的小须鲸拿到饭店出售。日本人再次捕鲸还说，我们是拿来研究的。其实日本人把鲸肉送到菜馆和饭店里，就想发财。日本人真会撒谎。我真的恨透他们了。

国家把鲸认为保护动物了。现在日本人还是要捕鲸。如果日本人不把鲸捕来吃，那国家就放心了。我们该怎样让日本人不捕鲸呢!这就让祖国担忧了。

我想：和日本人讲和，不行，他们还会捕鲸的。还是就让他们捕鲸，不行。我们暗中保护鲸呢，不行。跟日本人总统谈条件，不行，不行，都不行。

我们只能眼睁睁地看着鲸被日本人捉去吃了吗!我们中国人一定会想尽一切的办法拯救鲸的!

身为一名中学生，我们有责任保护环境，关心地球，及时发现环境，水资源的问题，保护地球。

缺水的危害

生物学研究表明：人的体内的水只要丢失1%-2%变会感到口渴及浑身乏力，丢失5%则陷入半昏迷状态，丢失12%将会导致死亡。

长期处于缺水状态或急性脱水，就会引起各种病症。如：白内障，心律失常，脑血栓形成，有害物质积蓄

记得看一个关于缺水的新闻：炎炎烈日和肆虐的干热风使河北省经受着日益干旱的严重威胁。根据最新统计，截至5月底，河北全省的受旱面积达到3752万亩。水库、洼淀可用水量仅为12亿立方米。446座水库干涸，滦河断流，白洋淀水位降至干淀水位以下，16万眼机井出水不足或抽不出水。据河北省农业气象中心介绍，今年1至5月份，河北省平均降水量47毫米，比常年同期减少32%。河北北部张家口、承德、唐山、秦皇岛的绝大部分地区一直没有有效降水，属特大干旱。目前全省南部、北部未经浇灌的耕地干土层已达10厘米。 干旱使河北全省农业生产受到严重影响，城乡供水紧张，全省11个地级市普遍陷入缺水困境。其中兴隆县的人畜饮水已成为相当突出

的问题，全县10万人以及6000多头牲畜饮水困难。这个县地处石灰岩地带，雨水下渗快，县境内10条河流已断流，可利用水源相继枯竭，靠水窖截留雨水生活的群众也已无水可存。如今，全县20个乡镇19个处于严重缺水状态。每天约有5.7万人要往返几公里甚至几十公里背水、驮水维持生活。

世界淡水资源的65%集中在10个国家里，而占人口40%的80个国家却严重缺水。如果一个国家年人均水量在2000立方米以下，就是缺水的国家。中国人均水量不富，是缺水国家之一。

水是生命之源，如果没有水树木不会生长，如果没有树，生命会停止呼吸，如果没有树，地球就会变得枯黄衰竭，所以我们要保护这珍贵的水资源，就要做到以下几点：

一、 水是生命之源，节约用水，保护水源，爱我太湖，爱我“母亲河”，爱我300万平方公里的富饶海洋，爱护祖国的所有“蓝色国土”。

二、 节水为荣，随时关上水龙头，防止滴漏

三、 慎用清洁剂，尽量用肥皂，减少洗涤剂中的化学物质对水的污染。

四、 提高工业用谁的重复利用率

五、 农业上改打水灌溉为喷灌、滴灌、淋灌

六、 改变一些不良的用水生活习惯，如洗衣，刷牙似的不间断放水改为间断放水

七、 使用新技术、改革工艺，如生产节水型用具和家电

海洋也是水资源中的一种，海洋的污染也是十分严重的。 海洋污染的危害

海洋面积辽阔，储水量巨大，因而长期以来是地球上最稳定的生态系统。由陆地流入海洋的各种物质被海洋接纳，而海洋本身却没有发生显著的变化。然而近几十年，随着世界工业的发展，海洋的污染也日趋加重。

局部海域水体富营养化;油海域至陆域使生物多样急剧下降;海洋生物死亡后产生的毒素通过食物链毒害人体

在新的世纪里，我们渴望美丽的地球，绿色的家园，湛蓝的天空，清新的空气。但是，由于人类的肆意破坏、污染、浪费，使地球变得千疮百孔、遍体鳞伤。人类受到了大自然的惩罚，逐渐意识到了环保的重要性。在我的家乡陆川，一条九州江贯穿县城。听老人说，以前九州江的水清澈见底，河畔的沙滩上还不断地涌出温泉，吸引着四面八方的游人，夏天，人们还常常到江里游泳。而现在，九州江河水混浊，还夹带着恶臭，各种垃圾漂浮在江面上，温泉大大减少，需要用抽水机才能抽上来，朋友们，我们人类是聪明的，我们已经觉悟到应该吸取教训，已经开始制止破坏行为，要从我做起，从现在做起，为了地球，为了人类的将来，也为了让我们永远拥有一个美好的生存环境，我再次向大家发出建议：

1. 共同建设“节约型社会”，节约一滴水，节约一度电，节约一张纸。

2. 节约用水，用完水后及时拧紧水龙头，避免大开水龙头，提倡用脸盆洗手、洗脸;节约用电，电器不使用时应关闭电源;节约用纸，多用手绢、抹布，尽量两面使用纸张。

3. 实行垃圾分类化。这样不仅能减少环卫工人的工作量，还能更好地起到废物利用，减少污染。

4. 节约资源。建议大人买菜时，少用塑料袋，尽量用竹篮子。用笔尽量用可换芯的，减少圆珠笔外壳的浪费与垃圾量。

5. 外出吃饭尽量不用一次性饭盒。绿色消费，尽量少使用一次性用品，多使用耐用品。

6. 人类要想征服可怕的大自然，就必须尊重自然，爱护树木，爱护动物，爱护大自然的一切。

作为新时代的中学生，我倡导同学门提高保护环境，保护水资源的意识，也建议叔叔阿姨们加入我们的队伍中来，为保护环境、造福后代贡献自己的力量。因为：保护环境，刻不容缓!希望我们早日到山青水秀、鸟语花香、百花争艳、生态良好、景观优美、植物多样、清新舒适的人居环境中生活!

Today, Chinas economy has made the great achievement. More and more

foreign people come to China to seek for cooperation. It is true that peoples

life standard has been improved a lot during the last decades, but the

environment has been polluted badly. When I was very small, I could see the

green trees and clean water around my hometown, but now, the river becomes

smaller and the rubbish can be seen everywhere. I feel so sad about it. We have

sacrificed so much to chase the profit. If we cant save the environment, we

wont live the comfortable life. For us, we should not throw away the rubbish

and plant more trees. The little things we do will make a great difference.

Last Sunday my father and I went fishing along a river. We found the water so dirty that we could hardly catch fish in it.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed.

If the river water all over the country is polluted like this， no living things will exist in the water. As we all know， environmental pollution does great harm to living things and human beings. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

上个星期日我和爸爸一起去钓鱼。我们发现水太脏了，我们几乎不能在它的鱼。

沿着这条河的许多工厂总是把废水和垃圾倒进河里，使河水受到污染。这样，河里的大部分鱼都被杀死了。

如果这个国家的河水都被污染了，水里就不存在生物。我们都知道，环境污染对生物和人类都有很大的危害。现在越来越多的人开始意识到这个问题有多严重。我国政府正在尽最大努力采取措施打击污染。我们期望在每一条河流中的水将在长时间内变得更清洁，更清洁。

the only mother of human beings, is now facing a great threat-environmental pollution. Therefore, it is important for all of us to protect the earth, for she is only home to all peoples living on it. Throughout the world, environmental pollution is becoming more and more serious as a result of various reasons .First of all, the rapid economic and social development is producing a large amount of pollution in form of gas, waster and waste;. Besides, Peoples poor awareness of environmental protection is also another important factor contributing to environmental problems. For example, a large number of people have developed the habit of using plastic bags and white lunch boxes which do great harm to environment. What’s worse, many people are cutting ting down increasing number of trees, causing soil erosion. In addition, the management of the government also contributes to serious pollution. Therefore, we must take measures to prevent the earth from being polluted. Living on this beautiful planet, we must actively contribute to beautifying the environment. Its important to improve the environmental awareness of human beings. The factories should reduce the discharge of sewage and gas. People should learn to use clean energy such as Solar, Nuclear and Hydrogen energy. The government should make some laws to ban different harmful pollution. Let’s change words into action! The earth is our only home. From now on, everybody should protect the environment and make our home a better world.

"Bumper harvest, bumper harvest!"!" Cried one of the fishermen, happily jumping up like a child. After a while, the full cabin fish alive and kicking, calm sea filled with coming from all sides of the fishermens laughter.........

Now, like this "fish and shrimp full cabin" scene has been very rare. In todays market, is the most common fish pound at least to dozens of yuan, more serious pollution of the ocean, the ocean resources gradually dried up, seafood production, prices rise, it illustrates this point?

In the ocean of natural calamities and man-made misfortunes emerge in an endless stream today, human pollution is often not from the original intention, but it is caused by the unexpected effect. The British Petroleum oil, because the drilling platform explosion, caused by the oil spill in the Gulf of Mexico, to 9900 square kilometers of sea water is seriously polluted, so that tens of thousands of seabirds soaked in oil to move, die in hunger and misery, makes countless fish poisoning death; and the Japanese earthquake and tsunami triggered a nuclear leak the marine pollution is more serious......

The sea is so vast that it is because the rivers and streams flow into the Yangtze River and then run into the sea. If we do not solve the pollution problem from the source, then no matter how people clean up the sea, there will always be sewage flowing into the sea, and all the efforts will be futile. Now, streams and streams are often seriously polluted, or they become places where people dump rubbish or are loaded with pesticide cans. Finding a clear stream in an inhabited area can be very difficult today!

In any case, the protection of the oceans can not be achieved by individual forces, and the protection of the oceans depends on the joint efforts of all mankind. I do not want one day in the future, our descendants can only imagine the image of the vast and wide sea.

This is not only the wish of a pupil, but also the wish of all mankind, isnt it?

There is only one earth. He is the cradle of life, is the homeland of all mankind. However, environmental pollution and ecological destruction of normal life has been on the social and economic development and peoples constitute a real threat. Care for the environment, advocate of civilization, is the humans moral responsibility.

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。

We desire to clean the earth, to earth for environmental health, home, eager to green, health, the health of the community...... Let us love to pay close attention to changes in the environment, with enthusiasm to spread the idea of environmental protection, with action to shoulder the responsibility of environmental protection. Begin from me, start from now, start from the side of the little things, the environmental commitments into actions.

记住，保护地球，就是保护我们自己。

Remember, the protection of the earth, is to protect ourselves.

我们住在这蔚蓝的星球里，这星球给予了我们生命，给予了我们万物，而我们，却无情将它们毁灭。

水，是万物最重要的资源，而我们，却污染了它，工业排出的废气，垃圾，最重要的是样它伤心的流泪，然而，如果没有水，人类就无法生存下去，动物将会死去，植物将会枯萎，因此，大家请珍惜水源吧！请把废弃排放到别处去，垃圾倒到规定的垃圾箱，注意节约用水。这样，地球妈妈就不会再哭泣。

树木，是支撑世界的栋梁，可以防沙尘暴，洪水。但我们，砍伐它，用来做房子，铅笔，使灾难侵犯了我们美丽的家园。3月12日是植树节，我们应该在所不辞，把小树培养起来，我们不应该再砍伐它们，应该保护它们，样它们巨恤支撑世界的栋梁！

地球是我们唯一的家园，我们应该珍惜它和它给我们的资源，只有这样，就再也不会哭泣！

第1篇：保护水资源作文400字

保护水资源有一次，我在河边玩耍，一不小心把一个球，踢进水里了，我和伙伴们都目瞪口呆，我们想该怎么办呢，我想呀、想呀，终于我想到一个办法，那就是用抓鱼的网子到水中去捞，我捞了半小时都没捞到球，但我却捞了一大堆脏的东西。比璐说剩菜剩饭全都丢在水里，和不要的东西也全丢在这里。后来，我在水中找了很长时间才找到，我又站到桥上去看水，只见水中有一股臭气，水面浮脏东西，我有时又看到别人在水中钓鱼，而且还吃鱼。水污染这样严重，我们使用水对我们身体有害，我们要保护环境，保护水资源，从小事做起从我做起。

还有一次，我在奶奶家玩，我看邻居拿着菜往后院去，我很好奇，就跟着去了，后来才知道，原来他是去后院水里洗菜去的，还好我及时阻止他了，要是我当时不阻止他的话，那这个菜吃了就会生病，水里面的细菌也全爬到菜上了，而且大家也看不见，因为细菌很小。

第2篇：保护水资源作文400字

水是生命的源泉。没有了水我们不能做许许多多的事，比如：洗衣、做饭、洗澡……而这些事情对于我们来说是多么的重要。植物不能没有水，因为没有水它们会干枯；动物也不能没有水，因为没有水它们会渴死。

保护水资源从身边做起。我要请工厂的叔叔、阿姨们不要把有害化学液体倒入江河湖泊中；我要请那些爱玩水的小朋友们，制止一下，不要再浪费水资源了；我要请每个人顺手关一下水龙头，否则世界上的最后一滴水那便是人类的眼泪。请大家不要把污染水资源的东西乱扔到水里面，因为那样供我们用的自来水会慢慢减少。洗菜的水可以倒进马桶里，洗衣服的水可以冲厕所，洗米的水可以拿来洗菜…… 水是可以做不计其数的许多事情。

水是一幅美丽的山水画。水是大自然赋予给我们的生命。让我们从现在做起，让我们一起行动吧！保护水资源，爱护水资源，珍惜水资源。我相信地球上的最后一滴水肯定不是人类的泪水。

第3篇：保护水资源作文400字

水，是生命之源，任何物质都不可替代。没有水就没有生命，更谈不上什么文明和发展。

然而，由于世界人口的剧增、人类的过度索取和浪费，以及工业污染等原因，世界淡水资源越来越匮乏，人类正面临着严重的水危机。水是那样的普通，普通得让人须臾不可缺少而又随时可以忘记。人只是在饿的时候想到吃饭，渴的时候想到喝水，而对于粮食和水本身，可以说关心得很少甚至从未关心过。

至今，绝大多数人的心目中，水仍然是取之不尽用之不竭的，到处都是对水资源的过量开采、挥霍浪费以及粗暴的践踏与污染。水资源是人类的共同财富，保护水资源，必须提高人们对水资源的认识。

国家应制定出相应的节水法规，大家应自觉养成节约用水的良好习惯。我们应该从身边小事做起，在生活中节约用水，与浪费水资源、破坏水资源的行为做斗争。如果人类继续破坏和浪费水资源，那么人类看到的最后一滴水，将是自己的眼泪！

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

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!

水是生命之源，一城一水，因水结缘。今天，我参观了“山里人家·水管家”体验店，了解水的知识，动手做了有趣的小实验。大家知道多少关于水的知识？现在请跟我一起走进山里人家高端体验店，探索“水世界”吧！

一走进大门，我就被摆着的各种瓶瓶罐罐吸引了。看，有胖乎乎的大瓶饮用水，有小巧玲珑的瓶装水，还有一种奇特的方形饮用水……就在我看得眼花缭乱时，一位解说员姐姐就给我们介绍：“世界上有很多水，几乎成了一个“水球”，但地球虽有70。8%的面积被水覆盖，在全部水资中97。47%是无法饮用的，余下2。53%淡水中，有很多是难以用的。我们真正能喝的仅占地球的0。26%。”我心中的暗暗惊呼，这么少，看来我们要珍惜水了。

接下来，解说员又介绍了水资源污染、缺水的后果、能饮用的水。大家在叽叽喳喳，眉飞色舞地讨论刚讲的知识时，解说员拍拍手：“接下来我们要做几个有趣的小实验。”大家立马端端正正坐好，一双双小眼里充满了欣喜与期待，让我感受最深的是测“余氯”。首先解说员拿了一瓶小小的白色药剂，又用了三个杯子分别装了矿泉水、纯净水和苏打水。解说员分别往矿泉水、纯净水和苏打水里加四滴药剂，矿泉水和苏打水依然没变，可纯净水呈现出了黄绿色。解说员又倒了一杯纯净水，叫一个男生上去用手指搅了搅，大家都致着眉，不知道解说员葫节里卖了什么药。解说员滴了四滴药剂——咦？没变色呀？解说员笑了：“因为水里的余氯被手指吸收了。”哦！大家都恍然大悟。

最后到了涂鸦时刻，解说员拿出一个个白色瓶子，让我们画上今天参加活动的心得体会，我画的是在水源充足的南方，人们一点都不珍惜水，把水龙头拧到最大，在水少的可怜的北方，人们站在干涸的河岸上，捧着碗求水，人们身边都是死鱼，这幅画呼吁大家要节约用水。

这样的活动既可以教育我们要节约用水，又给我们科普了很多知识，我喜欢这样的活动。

从前，水资源污染很严重，到处都是臭水。可是，有一滴水，它叫透明水。它去过很多污染水公司，比如：垃圾站、臭水沟，等等。

透明水很喜欢冒险，所以，它今天又要去一家严重污染水公司——化学实验室。它逆流而上，终于来到了化学实验室的排水管，那里排放的全是绿色的污水，而不象是透明水那样好看。它突然看见了很多和自已形状一样的水，它问它们：“你们怎么了?身体不舒服吗?”

它们回答说：“我们身体里有些不好的东西，使我们发出一些难闻的气味。我们也想像你一样透明、明亮。”它们提醒透明水：“你不要在这里呆太久，要不然，会象我们一样的。”透明水赶紧往家里跑，可是，它回家的方向却被垃圾堵住了。它伤心的哭了起来，眼泪流到嘴巴里，没想到是辣的，而不是咸的。因为它回不了家，所以在排水管里呆了三天三夜。第四天黎明，它起床看了一下自已的身体，发现，它又变成透明的颜色了，而且，水里的垃圾不见了。然后，它赶紧跑回家里，扑到妈妈的怀里。妈妈问：“儿子(透明水)，你怎么了?”透明水说：“妈妈，我很想你。几天前，我遇到了象我一样的的千千万万的朋友，他们好象生病了，全身都是绿色的，而且散发着一股难闻的气味。”妈妈说：“孩子，你的那些朋友，前段时间确实生病了，不过，现在他们已经康复了，它们与你一样，也变成了透明的水。”小水滴好奇的问道：“为什么呢?”，妈妈答道：“因为实验室的叔叔阿姨们买来了专门处理污水的机器，重新过滤后，污水变成了清澈的水。这样，就不会再有污水排放了，所以，它们也就变成了与你一样，透明的小水滴!”透明水听了，高兴极了。

透明水又回去找它的朋友们，这时，成千上万滴透明水变成了一条大河，他们在河水中自由自在欢快的玩耍。
