为什么我们应该保护野生动物英语作文初二(汇编20篇)

Russian Scientists Surrounded by Polar Bears

俄罗斯科学家被北极熊包围

Relief supplies finally arrived on a remote Arctic island where a group of scientists had been trapped in a weather station. Up to a dozen polar bears had surrounded the station on the island of Troynoy and set up camp approximately two weeks ago. The bears were becoming more aggressive over time, killing one of the stations dogs and breaking a window. On Wednesday, a helicopter that picked up supplies from a nearby vessel arrived with dogs and flares and was able to scare away the bears and allow the researchers to get back to work.

救灾物资终于抵达了偏远的北极岛屿，有一批科学家被困在那里的气象站中。大约两周以前，十几只北极熊将特洛伊诺伊岛(Troynoy Island)上的一个气象站团团包围，并在那里安营扎寨。随着时间的流逝，北极熊变得越来越有攻击性，咬死了气象站的狗，还打破了窗户。周三，一架从附近船只上携带犬和照明弹物资的直升机到达岛屿，能够将北极熊吓走，让科学家正常工作。

今天早上，奶奶带我去买菜，一进菜市场，便发现菜场边围了许多人，我好奇地凑过去一看，不看不知道，一看吓一跳，原来是一位年青人在卖青蛙。只见那位年青人从一只蛇皮袋里捉出一只青蛙，青蛙在年青人手中拼命地挣扎，年青人拿出一把尖刀朝青蛙的肚皮上划了一刀，然后伸手掏出青蛙的五脏六腑，剥了青蛙的“绿大衣”，青蛙悲惨地叫了一声，便死于非命了，我看得心惊胆颤，十分心痛那些青蛙。

青蛙是捉害虫能手，它是对农作物有益的小动物，它的身体的颜色和草的颜色接兵，这样便于它利用伪装来捕捉猎物，它的舌头长长的，沾满了黏液，只要小害虫从身边飞过，它就猛地往上一跳，张开大嘴，从速伸出长长的舌头，一下子把害虫捉住吃掉，青蛙每天平均要吃70多只害虫，一年就能吃1万多只害虫，这是多么大的数字呀!试想一下，如果没有了青蛙保护庄稼，害虫大量繁殖，庄稼遭秧了，最后受害的将是我们人类自己。

青蛙还是歌唱家，每到夏天的夜晚，只要有一只青蛙叫得欢，就会有几十只青蛙甚至几百只青蛙跟 着回应，耳边听着欢快的“呱呱声”仿佛是一支优美的交响曲，伴我入睡。

可是随着人类有意和无意识的破坏，青蛙的数量逐年减少，所以保护青蛙是我们每一个人的责任，行动起来吧，抵制青蛙上餐桌，宣传青蛙是人类的朋友，不要让青蛙从地球上消失，留住可爱的生命。

I like animals very much， such as horses，monkeys， cats， tigers and so on。 But I like dogs best。 Why？ Because they are very cute and nice。

I have a white dog。 Its name is Bobo。 She is a female dog。She comes from Beijing，China。She wears white clothes and she has two big eyes and a small month。She often walks round and round at home。It has nothing to do。She likes eating ice—cream so much。So do I。When I eat ice—cream，she will look at the ice—cream carefully，So I will give her some to eat。

I think Bobo is the cutest dog in the world。

My favorite animal is dog, my family has a puppy. His name is wangwang, he that is yellow, is really beautiful. He has a pair of bright eyes sparkly.

His two big ears perked up really high like a birds wing, but air. Sometimes also shake his tail to show your tongue with me, where I went with it, really like a small heels. I patted him on the head, it is licking my fingers, I feel itchy. Lovely!

But he has time, low head, let me feel very strange, but I dou dou it his mood suddenly. This is my dog barked. It is very cute!

大自然是一个很奇妙的世界。有许许多多的动物，天上飞的，水里游的，地上跑的，还有各种各样的植物，当然还有机智聪明的人类，从而营造了一个丰富多彩的世界。

动物家族是自然界不可缺少的一部分，然而却遭到了严重的破坏。人类为了满足自己的私欲，不断地捕杀动物来换取金钱，从而迷失了自我，导致有些动物失去了自己的亲人。

在肯尼亚北部萨布鲁大草原上，一只非洲象诞生了，它就是罗拉。一对扇子大小的耳朵上有一块蝴蝶斑大小的标记，这是罗拉独特的标记。它是一个很可爱的大象宝宝，可它的遭遇却如此不幸。

充沛的雨季已经过去了，东非草原的旱季是整个地球最热的地方，罗拉家族要去寻找一块新的领地。在途中遇到了一只小公象，它叫雷昂，雷昂的家族遭到了人类的屠杀，而雷昂的妈妈也在这次屠杀中永远的离开了雷昂，当雷昂再次见到妈妈的时候，尸体已经面目全非，两颗雪白的牙齿已经不见了，连象鼻也被割下来了。罗拉的妈妈决定收留它，对待它就如对待自己的孩子一样，这使雷昂感觉到了家的温暖。

可是好景不长，一场突如其来的灾祸降临了，在它们正准备休息的时候，近处的树木中出现了人的影子，一声巨大的轰响，罗拉的妈妈倒下了，罗拉永远的失去了妈妈，对于雷昂来说，这已经是它第二次失去亲人了。

一对美丽的象牙，就会死去一条生命，难道金钱真的比生命还重

要吗?人与动物之间同样都是生命，为什么会有巨大的差别?动物是我们的朋友，不是我们赠钱的工具。我们应该保护它们，让它们有一个温暖的家，而不是杀它们，去摧毁它们的家。放下你们的枪去保护它们吧!不要在让它们担心受怕，让那些刚出生的小象可以健康的成长，有家人倍伴成长，开心的成长。保护它们吧，给它们一个安心的家。

Yours，

Da Ming

If I have a lot of money

If I have a lot of money, I will have the chance to do what I want to do.

First I’ll travel around the world, because I love traveling, and then I’ll give some money to schools and charities. I’ll try my best to help the people who are in trouble. Next, I will buy a big house with a garden and a swimming pool for my parents, so they will live a happy life. I’m sure we will enjoy a better life.

一转眼，我已成为一名小动物保护协会的会员了。

一个酷暑难当的夏日，我接到了一个紧急救援电话：您好!我在玫瑰街珊瑚小区23号楼下的花坛内发现一只受伤的流浪猫。这只猫的伤势十分严重，请立即到达现场!放下话筒，我和同事们就带上医疗箱，驱车前往。 我们到达目的地后，果然看见一只流浪猫奄奄一息地躺在地上，它的后腿上有一道很长的伤口，伤口里似乎还有一些杂物，伤口四周已经溃烂，流着脓。我和同事们赶紧用酒精为它消毒，再用纱布简单包扎了一下，然后将它带回小动物保护协会。

回到保护协会，我们立刻投入治疗工作中。 我小心翼翼地剔除掉猫咪腿上伤口中的杂物，进行深一层次的消毒。接着，我把溃烂的地方用手术刀轻轻挖去，随后上药，缝合伤口，最后用纱布缠在伤口上。直到此时，我才深深地舒了一口气。我看向猫咪，发现它的眼里流露出感激的神情，好像在向我致谢。接下来的几天里，我们还定时给猫咪换药。 一个月过去了，猫咪的伤口痊愈了!我和同事们都很高兴。接着，我们在网上发布了猫咪的信息，希望有人能收养它，并好好对待它。

不久，一对夫妇表示愿意收养这只猫咪 如果我是小动物保护协会的会员，我会为我的动物伙伴们做得更多更多!

Low-carbon life means a kind of lifestyle in which people do their best to reduce energy consumption and carbon dioxide emissions.

Then，how can we live a lowcarbon life?Firstly，we should recognize that the lowcarbon life is not only a kind of lifestyle but also a life attitude.Each of us is responsible for the greenhouse gases in our daily actions.To combat climate change we have to take the combined efforts of everyone on the planet.Secondly，we should develop good habits in our daily life.Paper cups are made from cutting forests.We should try not to use them because trees can absorb carbon dioxide and reduce greenhouse gases.Similarly，lights should be turned off when they are not used，which will greatly reduce electricity consumption.

In a word，small actions above can make a big difference.

科学家们把现存的人类已知的动物分为无脊椎动物和脊椎动物两大类。科学家已经鉴别出46900多种脊椎动物。包括鲤鱼、黄鱼等鱼类动物，蛇、蜥蜴等爬行类动物，青蛙、娃娃鱼等两栖类动物，鸟类以及红熊猫等哺乳类动物等。下面是小编为大家精心推荐的有关于动物的英语作文，希望大家喜欢。

【关于动物的英语作文篇一】

Dolphin is my favourite animal.

It is one of the most precious animals. Their bodies are very long, about one zhang. Dolphins live in the sea. They live on fish, shrimps and so on.

Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger in the past years. How helpful the dolphins are!

Dolphins are very clever. People often train them so that they can give a dolphin show which brings people a lot of happiness and joy.

Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. Many people make money by hunting dolphins. If we don’t protect them, maybe we’ll lose our good friends one day. As a student, I hope more and more people should take actions to protect dolphins.

地球上的居民们：你们好!

据有幸飞上太空的宇航员介绍，他们在天际遨游时遥望地球，映入眼帘的是一个晶莹的球体，上面蓝色和白色的纹痕相互交错，周围裹着一层薄薄的水蓝色的“纱衣”。

但是，地球上的居民们却不曾知道这个美丽壮观的星球，正遭受着怎样的破坏和严重的威胁。

据资料统计，地球上有23%的耕地受到破坏。有许多哺乳类动物和鸟类濒临灭绝，四分之一的人因此得了各种疾病。所以，保护动物是很重要的。现在有许多动物在一瞬间就会奇迹般消失，这都是因为人们平时的行为造成的。所以保护动物就要从身边的一点一滴做起。近些年，一些不法商贩为了达到自己的经济利益，大肆捕杀动物，造成动物的食物链中断，动物之间的生态失去了平衡，有些动物开始寻找新的食物链，人类就成了它们生存下去的牺牲品。没有了动物，植物的食物链也遭到破坏，人类的食物链也会中断，长此以往，就构成地球上的恶性循环，降临在动物身上的命运终究会降临在人类身上。要知道，家园只有一个，地球不能克隆!

醒悟吧!地球上的居民们，让我们携起手来，用行动保卫家园，用热血浇灌地球。保护人类的朋友——最无辜的小动物，创造最和谐的动物家园，让世界的角角落落每一天都生机勃勃，焕发光彩，充满活力!

人类是生存在这个地球上的生命物种之一，我们在爱自己同类的同时，也应该尊重其他生命，善意对待和爱护我们身边的小动物。

每个人在一生之中，都会与各种生命相遇：小猫、小狗、小兔子、小乌龟……这些小动物是我们的伙伴、朋友，甚至家人。每一个有爱心的人，懂得生命意义的人，都会知道怎么善意关爱自己的伙伴。

被挖掉眼球的小狗、被汽油烧焦的小猫、被恶意投毒而死的动物……当这一桩桩骇人听闻的残害动物的事件不断发生时，我心里总有说不出的沉痛，我想这是任何一个有良知、有爱心、有正义感的人所不能容忍的事情。

虽然大多数人珍视身边动物带给我们的爱和友情，但是仍有人不负责任地抛弃他们的宠物，甚至虐待它们，于是才有了这一只只的流浪动物。

绝大部分城市流浪动物的生存状况令人十分堪忧：它们被遗忘在角落的生命，不受重视;它们身体遭受病痛的折磨;它们无时无刻不在忍受着残疾带来的痛苦;它们承受未绝育带来的生殖繁育风险，小宝宝一出生就面临着巨大的死亡危机;它们经常要面对酷暑、严寒和饥饿，四处寻找躲藏之处;它们时刻面临着各种危险，每一刻都有可能惨死在街边;它们甚至还要面对一小部分人为满足自己变态的心理而做出的种种虐待和伤害……

残酷的生存环境、悲惨的生活遭遇，使得我们身边的这些伙伴的生命凋零……

真正的爱是对弱者或蒙难者发自内心的悲悯和关怀，是不假思索伸出的援救之手。在此，我郑重呼吁各界尊重生命、关爱生命的有识之士：

1. 尊重生命，尊重动物，不吝啬自己的爱心;

2. 无论自己的宠物年老、体弱、生病还是残疾，都不放弃、不抛弃它们;

3. 保证动物不受饥渴、伤害和疾病威胁;

4. 保证动物有一定的自由，让它们生活无所恐惧，能自由表达天性;

5. 有能力和条件的人，对流浪动物进行有责任感的收养、领养、寄养;

6. 依法合理、人道的利用动物;

7. 不从非法商贩处购买伴侣动物;

8. 不虐待、不伤害流浪动物;

9. 将“关爱生命，善待动物”的理念传播给身边的每一个人。

相信我们一点点的爱心和所做的这些简单的事情，就能够让那些还在外面流浪的小动物们重新获得一个温暖的家。

I have a cat .Its name is Mimi. Its very lovey.My family all like it.

It always plays with me every day .It has black and white fur.As long as we sayMimi,It right away runs to you.

Its very good!so My family all like it!

“我想回家，我想找妈妈……”一阵阵声音从教室里传出来，原来这是小鱼的呼唤。如果让你关在屋子里不出去，你会不会感到不快乐？鱼儿也一样！

在今天的教室里，多了几条活泼可爱的小鱼，看着它们在鱼缸里转来转去，一个声音从我的心中传出：“让小鱼儿回家吧，让它得到属于自己的自由！”于是，我们在老师的带领下，准备去放生小鱼。

走在山间的小路上，我不由得心想：我是多么依依不舍呀！我抱着鱼缸不敢走得太快，怕鱼儿在鱼缸里会动荡不安，可又怕走得太慢会让它在水中的伙伴等得太久。我们好不容易走到了盘龙山脚下，啊，这里山清水秀，鸟语花香，真的让人流连忘返！

我们来到池塘边，池塘里的水清澈见底，碧波荡漾，不时有黑色的小蝌蚪在水中自由自在地游着，好不快活！

准备放生了，我们小心翼翼地将小鱼倒入水中，那一刻，我是多么地不舍呀！小鱼在水里游来游去，像是在感谢我们，又像在和我们告别……可我硬是转身离开了，心里异常沉重。回去的路上我看到路旁的小草在向我点头，玉兰树似乎在向我点赞。我的心情也逐渐好转了，因为我知道我今天做了一件令自己都敬佩的事！

“劝君莫食三月鲫，万千鱼仔在腹中。”我们一定要保护动物，让所有的动物朋友都能得到属于自己的自由和快乐！

谁能告诉我哪里是我的家？谁能告诉我哪里有我自由的天空？谁能告诉我我的父母在哪里？谁能告诉我

我叫xx，原来有一个幸福的家庭，家中有爸爸妈妈的疼爱。每当晨光熹微，我在伙伴的呼唤声中苏醒，伙伴们在林间嬉戏着。妈妈早已为我准备好丰盛的早餐，快乐的一天就从这里开始 暮色降临，爸爸在一旁给我讲闲暇的故事，林子里的一切都那样安谧。那时我们在这林子里生活得多么幸福呀！

可是好景不长，有一天来了一群猎人，他们拿着猎 枪四处寻找猎物，我的同胞有好多已经被他们打死了，爸爸说它们都被卖到大酒店里去做特色菜 小鸟点盘 。我担心地问爸爸、妈妈： 我们是不是也要遭受这样的厄运呢？ 妈妈从容地：说： 孩子别怕，有我们在。 但从他们不安的眼神中，我感到了恐惧的来临。惊魂的枪声时常打破了树林的宁静，伙伴们的呼唤声越来越少，爸爸、妈妈常常护着我躲在窝中不敢轻易地行动。

这样提心吊胆过了几天，灾难终于降临到我的家中。爸爸为了保护我，让我骑在他的背上，带我飞走。而妈妈却留下来引开猎人，临行前，爸爸叫妈妈小心一点，在一片告别声中猎人的枪声已经响起，爸爸只好带着我一步三回头地飞走了。在一阵枪响之后，我的妈妈被 打死了。我大喊一声： 妈妈 猎人发现了我和爸爸便向我们举起了枪。爸爸躲开了猎人的子弹，带我向一片森林飞去，猎人依然穷追不舍。爸爸将我安置在茂密的丛林中，自己去跟猎人搏斗。我的直觉告诉我，爸爸这一去就回不来了。果然，一阵枪响和惨叫之后，我的爸爸死了。

从那以后，我饱偿了没有母爱、父爱的痛苦，虽然猎人走了，我的生活并没有变好。过了几年，又有一群人把这片森林砍伐了，我已经没有地方安家了，只能四处盘旋，流浪。

人类快快醒悟吧！不要再伤害野生动物了。地球是我们赖以生存的家园，给我们一点生存的空间吧！不要因为你们的贪婪而破坏我们幸福的生活！这是一只小鸟在呼吁，这是一只小鸟在哭诉！

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

Do you have a dictionary?I think almost everyone has one.But, how often do you use a dictionary? I dont believe that everyone makes good use of it.You may come across lots of new words in your study and you will ask someone for the answer.But if you have a dictionary, please dont let it sleep. You should make better use of it.

It was my first time to go there. The moment we arrived there, we found that the

building was grand. When we walked into it, there was a big hall in front of us.

And then there were several rooms to show different kinds objects. There was a

room for collecting scripts and paintings. There was another room to store

clothes and shoes in the old times. The next room was for collecting the daily

necessities in the old days. In a word, all the things in it had a long history.

I learnt some knowledge from it.

烤鸡;烤鸭;各种各样的野味，早就是餐桌上见怪不怪的一道“家常便饭”了。电视上也报道过不少拯救国家级保护动物的节目，提倡世界各地的人们要保护动物。可是，为什么有的动物人们会不惜一切代价去挽救，而一些就要被摆在餐桌上供人们享用呢?不是提倡保护动物吗?

答案很简单，因为人们不惜一切代价拯救的动物叫“国家级保护”，而被摆在餐桌上的叫“家禽”。为什么?它们同样是活泼可爱的生命个体;同样是有爸爸妈妈疼爱的乖小孩;同样是被人们统称为动物。可是为什么?稀少的动物要保护，而多的却要吃掉。这边打着“保护动物”的头衔，那边却大口大口地咬着鸡鸭鱼肉。为什么那些国家级一出生就要被保护起来，过着比某些弱势群体还要舒服，而家禽一出生就是养大，等待它们的就是残忍的虐杀，然后做成各式各样的美味，被摆在餐桌上，就是为了吃它们的肉。

难道它们的生命不是生命吗?为什么要这样对待它们呢?如果有一天，换我们自己要被它们杀掉，然后做成各式各样的美味，供它们享用，我们自己的感受会是怎样的呢?

虽然我不是什么大作家，不能用很美的句子打动你们的心，但我想说的永远只有一个：同样是生命就应该受到尊重，我们没有权利决定别人的生死，饲养它们，充其量就是一个爱心的行为举动。

它们的生命也是生命，看完，请您保护您身边弱小的生命，谢谢!

Now the earth is yellow and the green is decreasing. Whats going on here? It turns out that people are cutting down trees, which not only causes the birds to lose their home, but also causes the collapse, the flood and so on. Without trees, our earth would seem to be missing a supporting beam.

Now each store all follow our hobby, mass production soda, and soda "appearance" is the jar and jar is a kind of pollution, the road, the park even schools have become their home. The cans are made of aluminum, which is also harmful to the human body.

You know what? Waste batteries contain a lot of heavy metal pollutants - chromium, lead, mercury, etc. The effects of pollution from used batteries are slow and profound.

Before the river bottom, can see Derek fisher, now the factory in order to improve the efficiency, they put the stream discharge sewage as a good place, river sewage got dirty, passing pedestrians were quickly leave.

To conserve water is to protect our environment, which is to save resources. We want to own practical action to protect the environment, the most simple is to start from oneself, pay attention to save water, such as: use after the tap turn off the tap at any time; Water the washing water with water, rinsing and flushing. Dont think that a few drops of water in a water bridle cant make a difference. A water bridle drops a drop of water every second, and a year is a waste of 36 square water. If a family saves one person per month, how much water is saved in a month?

Fortunately, people have learned the earth now to be polluted, everyone has to act, I hope people who didnt act, they bent and picked up the paper on the ground, a low back, let us tomorrow is more beautiful, neat!
