There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

Grilled chicken. The roast duck. All kinds of meat, already is normal on table a "routine". Television also reported many save a national protected animal, encourages people from all over the world to protect animals. But, why do some people will do whatever it takes to save animals, and some will be on the table for people to enjoy? Not advocate protect animals?

The answer is very simple, because people at all costs to save animals is called "the state-level protection", and was called "poultry" on the table. Why is that? They are also lively individual life; There are also mom and dad love; a lovely kid The same is collectively known as animals. However, why? To protect rare animals, but more to eat. Side in the title of "animal protection", there are big mouth to bite a serve fish or fowl. Why the national birth will be protected, live more comfortable than some vulnerable groups, and poultry was born is raised, waiting for them is cruel, and then made into a variety of delicious, is on the table, is to eat their meat.

Isnt their life life? Why do this to them? If one day, in our own to be they kill, and then made into a variety of delicious, for them to enjoy, our own feelings of what?

Although I was not a great writer, cannot use a beautiful sentence touched your heart, but I want to say only one forever, also is the life should be respected, we have no right to decide the life and death of others, feeding them, at best, is the behaviour of a love.

Their life is life, watching, please protect your side weak life, thank you!

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!

My hometown is a beautiful small village, my father said that the original home of hanging about the village, is full of trees behind the house, lush and green all the year round, there is a small river east village, the water crystal clear, fish, the sky was crystal clear.

The few families lived in the village, the life is comfortable, but I dont know since when, the environment began to deteriorate. Say we river first, she was now the sewage river, there is a paper mill in the waste water into the river, the river with a layer of white foam, stinking, former aquatic plants and the fish disappeared, flowers reflection of the river was gone. Dad said the river but he was a child often play place, now people here to hurry past, wu hold its mouth. The river when you are sad all the day.

The earth is our home, a good environment is the premise of our happy life. In order to our survival homeland to sweet and comfortable, I put forward three Suggestions:

The industrial wastewater emissions dont, best can recycle after unified handling.

Second life garbage recycling, in order to reuse. Called on people to care for the environment, and in some poor hygiene area eye-catching warning label.

Three to supervision and control of air pollution, especially for those emissions exceed the chimney rectification within a time limit.

Around us there are many people environmental protection consciousness, I hope more people join the ranks of environmental protection, let the home environment is becoming more and more good.

我的老家是一个美丽的小村庄,听爸爸说，原来的老家村前村后、房前屋后到处都是树，一年四季郁郁葱葱，村东头有条小河，河水清澈晶莹，鱼翔浅底，天空湛蓝深远。

村里住着百十户人家，日子过得都还舒适，可是不知从什么时候开始，环境开始恶化了。先来说说我们的小河，她现在简直成了污水河了，岸边有家造纸厂在往河里排放废水，河面上泛着一层白白的泡沫，臭气熏天，昔日的水草和鱼儿不见了，鲜花倒影的河面不见了。爸爸说河边可是他小时候经常玩耍的地方，现在过往这里的人行色匆匆、捂嘴掩鼻。小河终日愁眉不展。

地球是我们的家园，美好的环境更是我们开心生活的前提。为了我们生存的家园能够温馨舒适，我提出三条建议：

一工业污水不要随意排放，最好能够统一处理后循环使用。

二生活垃圾要分类回收，以便再利用。号召人们爱护环境，并在一些卫生状况较差的区域贴上醒目的警示标志。

三对空气污染进行监督和治理，尤其是要对那些排量超标的烟囱限期整改。

在我们身边还有许多人环保意识淡薄，真希望有更多人加入到环保行列当中，让家乡的环境变得越来越好。

一幅漫画中画到：一个头戴鸭嘴帽，身穿制服的工作人员，从背包中取出一把斧头，朝森林里走去。

一到森林，他便从工作服口袋里拿出了一根香烟，悠闲地抽起来。突然，他看到一棵好树。便握着斧头跑了过去。还边走边想到了老板对他说的话：砍一棵好树，赏你50块钱。工作人员有模有样的试了试刀锋，“刷—刷”地砍了起来，动作是如此熟练。斧子在树身上留下了一条条刻痕。发出低沉得“咚咚”声。这声音打破了森林的和谐，只见一只啄木鸟飞来，朝工作人员的头啄去，并狠毒的说：“这段木头一定有虫……”

这就是那漫画，我看完了这幅漫画。心久久不能平静，“这段木头一定有虫”人的脑袋里真的有虫嘛?是的，有一条贪婪虫在人们的脑中游荡。是金钱创造了贪婪。正是贪婪毁坏了人们心中珍惜资源保护环境的意识。

例如说：塞特凯达斯瀑布是流量最多的瀑布。因为人类用水毫无节制，再加上沿河两岸的森林被滥砍滥伐，水土大量流失，使瀑布的水量逐量减少。游客常常乘兴而来，失兴而去。

我只想说：“地球上的资源不是无限的。我们不能浪费资源，因为没有了资源，人类也会灭亡。”我希望：人类不要再浪费资源了!

Animals Need Protecting

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 alone are considered in danger.

Why should people careBecause 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. WhyBecause hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

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 plant on the danger list. Slowly, the number of some animals in danger is growing.

植树节已过去了快一个月了，但是种树，保护森林还是受到人们的关注。

自上世纪五十年代以来，中国创造了世界人工造林的奇迹，据统计，20XX年至20XX年全国累计义务植树398亿株以上。但是人类对森林的破坏在速度与数量上更为惊人二十世纪九十年代的10年当中全世界森林资源大约减少了90000平方千米，占世界全部森林资源的百分之二点四。

毁坏开荒，乱砍滥伐，是我国本来就不多的森林资源破坏非常严重。火灾，虫灾也加据了对森林的破坏。

沙尘暴是一种风和沙相互作用的灾害性天气现象，它的形成与森林锐减，物种灭绝，气候异常等因素有养不可分割的关系。其中，人口膨胀导致的过度开发自然，过量砍伐树木过度开垦土地上沙尘暴频发的主要原因。我们砍伐一棵大树只需几秒，但是要长成的参天大树，要几年呢？

为了我们的家园，请保护森林。

It’s our duty to protect our school environment. We should clean the school every day. And we shouldn’t drop trash here and there. We should pick it up when we see trash on the ground.

We shouldn’t draw on the wall. If we all like our school the same as we like our homes, our school will be more beautiful. We will enjoy our study better. Let’s protect our school environment from now on, shall we?

I am a student from Xinhua High School in Chongqing，China. Informed that you have a vacancy for a student to serve as the spokesman for animals, I cannot resist my inner excitement,hoping to seize the opportunity to do something for animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I go and whatever I do, I usually keep in mind that animals are angels from the heaven, which bring us endless comfort and pleasure. I have been a panda lover since my childhood. Panda is so lovely that brings fun to people and they are regarded as the treasure of our country. Unfortunately，such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies.

Now, people dont speak hygiene, make the earth became very clean.

Factory waste water into the river discharge, discharge waste water will not think about it, if people drink the water, what will happen?

Also, people cut down trees, on the lawn, people will think of these things, without the trees, how do we have the fresh air and oxygen, no grass we how green home! Besides, if sandstorm comes, without the trees blocking, what will become of our home.

Why are both street trash can, this is to remind people not to throw rubbish everywhere, put the rubbish in the garbage can. But, a lot of people love throwing garbage everywhere, this kind of behavior not only damage the image of our home, what also polluted the earth again.

I want to tell everyone: "protecting the environment is to love life!" To protect the environment, we should start from the side, starts from me, to build our homes more beautiful!

现在，人们都不讲卫生，使地球变得很不干净。

工厂里的废水向河里排，排废水的人会不会想想，如果人类喝了那些水，会怎么样?

还有，人们砍伐树木，踏入草坪，做过这些事的人会不会想想，没有了树木我们怎么有新鲜的空气和氧气，没有了小草我们怎么绿化家园啊!再说，如果沙尘暴来了，没有了树木的阻挡，我们的家园会变成什么样。

为什么街道旁都有垃圾桶，这是提醒人们不要随地乱扔垃圾，把手中的垃圾扔进垃圾桶里。但是，很多人都爱随地扔垃圾，这种行为不仅损坏我们家园的形象，还让地球再一次的被污染。

我想告诉大家：“保护环境就是爱护生命啊!”要想保护环境，就要从身边做起，从我做起，把我们家园建设得更加美丽吧!

order to see the lovely animal, we need to protect them. We must protect the

environment, like not to throw the rubbish away, not to cut down the trees. We

condemn such behavior that killing the animals. Protecting the animals is

everybody’s job.

On Water Shortage

No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted. Actually, it has become so widespread that it has severely affected peoples daily life and hindered the development of the global economy.

A number of factors could account for the problem, but the following might be the critical ones. First, with the development of agriculture and industry, an increasing amount of water is needed. Secondly, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. Whats worse, pollution and waste of fresh water aggravate the situation.In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water. With these measures taken, it is reasonable

for us to expect a brighter future.

森林锐减直接导致了全球六大生态危机。

一、绿洲沦为荒漠

目前，全球荒漠化土地面积已经达到3600万平方公里，占陆地总面积的1/4，成为全球生态的“头号杀手”，而且每年仍以5万至7万平方公里的速度在扩展;全世界受荒漠化危害的国家达110多个，10亿人口受到直接威胁。这意味着，地球上已有1/4的土地基本失去了人类生存的条件。

二、水土大量流失

水土流失是森林破坏导致的最直接最严重的后果之一。只要地表有1厘米厚的枯枝落叶层，就可以把地表径流减少到裸地的1/4以下，泥沙量减少到裸地的7%以下;林地土壤的渗透力更强，一般为每小时250毫米，超过了一般降水的强度。一场暴雨，一般可被森林完全吸收。由于森林的严重破坏，全球水土流失日益加剧。目前，全世界有l/3的土地受到严重侵蚀，每年约有600多亿吨肥沃的表土流失，其中耕地土壤流失250多亿吨。全球地力衰退和养分缺乏的耕地面积已达29.9亿公顷，占陆地总面积的23%。

三、干旱缺水严重

森林被誉为“绿色的海洋”、“看不见的绿色水库”。据测定，每公顷森林可以涵蓄降水约1000立方米，l万公顷森林的蓄水量即相当于1000万立方米库容的水库。由于森林锐减及水污染，造成了全球性的严重水荒。目前，60%的大陆面积淡水资源不足，100多个国家严重缺水，其中缺水十分严重的国家达40多个，20多亿人饮用水紧缺。预计今后30年内，全球约有2/3的人口处于缺水状况。

四、洪涝灾害频发

水灾与旱灾是一对“孪生子”。破坏森林，必然导致无雨则旱，有雨则涝。大量事实说明，森林有很强的截留降水、调节径流和减轻涝灾的功能。森林凭借它庞大的林冠、深厚的枯枝落叶层和发达的根系，能够起到良好的调节降水的作用。森林的防洪作用主要表现在两个方面：一是截留和蓄存雨水;二是防止江、河、湖、库淤积。这两个作用削弱后，一遇暴雨必然洪水泛滥。

五、物种纷纷灭绝

科学家分析，一片森林面积减少10%，能继续在森林中生存的物种就将减少一半。地球上有500万至5000万种生物，其中一半以上在森林中栖息繁衍。由于全球森林的大量破坏，现有物种的灭绝速度是自然灭绝速度的1000倍。联合国预测，1990—2000年每年可能失去了1.5万至5万个物种。目前，地球上的物种已消失了25%，还有20%—30%存在灭绝的危险。

六、温室效应加剧

近代人类大量使用化石燃料，如石油、煤炭、天然气等，使得大气中二氧化碳的浓度在过去110多年里由270毫升/立方米上升到350毫升/立方米，到21世纪中期将达到600毫升/立方米。而森林吸收二氧化碳并放出氧气，每公顷森林平均每生产10吨干物质，吸收16吨二氧化碳，释放12吨氧气。

从这六大生态危机可以看出，破坏森林的后果是极其严重的。科学家们断言，假如森林从地球上消失，陆地90%的生物将灭绝;全球90%的淡水将白白流入大海;生物固氮将减少90%;生物放氧将减少60%;许多地区的风速将增加60%至80%;同时将伴生许多生态问题和生产问题，人类将无法生存。目前，森林锐减导致的一系列生态危机，已经构成了对人类的严重威胁。

土地资源是三大地质资源(矿产资源、水资源、土地资源)之一，是人类生产活动最基本的资源和劳动对象。人类对土地的利用程度反映了人类文明的发展，但同时也造成对土地资源的直接破坏，这主要表现为不合理垦植引起的水土流失、土地沙漠化、土地次生盐碱化及土壤污染等，而其中水 土流失尤为严重，乃当今世界面临的又一个严重危机。据估计，世界耕地的表土流失量约为230亿水土流失是指在水流作用下，土壤被侵蚀、搬运和沉淀的整个过程。在自然状态下，纯粹由自然因素引起的地表侵蚀过程非常缓慢，常与土壤形成过程处于相对平衡状态。因此坡地还能保持完整。这种侵蚀称为自然侵蚀，也称为地质侵蚀。在人类活动影响下，特别是人类严重地破坏了坡地植被后，由自然因素引起的地表土壤破坏和土地物质的移动，流失过程加速，即发生水土流失。

水土流失是我国土地资源遭到破坏的最常见的地质灾害，其中以黄土高原地区最为严重。我国目前水土流失总的情况是：点上有治理，面上有扩大，治理赶不上破坏。全国水土流失面积解放初期为17.4亿亩,到1980年约治理6亿亩。由于治理赶不上破坏，水土流失面积却扩大到22.5亿亩，约占国土总面积的1/6，涉及近千个县。全国山地丘陵区有坡耕地约4亿亩，其中修梯田约1亿亩，而另外3亿亩坡地正遭受水土流失的危害。

最近，土壤肥力下降，水土流失可使大量肥沃的表层土壤丧失。据统计，我国每年流失土壤约50亿吨，损失N、P、K元素约4000多万吨。

水库淤积，河床抬高，通航能力降低，洪水泛滥成灾。

威胁工矿交通设施安全。在高山深谷，水土流失常引起泥石流灾害，危及工矿交通设施安全。

恶化生态环境。20世纪30～60年代，人们对于水土流失灾害的认识还停留在对土地造成直接经济损失方面，但在60年代以后，开始联系到人类整个环境所受的影响，包括沉淀物的污染，生态环境的恶化等。

水土流失是地表径流在坡地上运动造成的。各项防治措施的基本原理是：减少坡面径流量，减缓径流速度，提高土壤吸水能力和坡面抗冲能力，并尽可能抬高侵蚀基准面。在采取防治措施时，应从地表径流形成地段开始，沿径流运动路线，因地制宜，步步设防治理，实行预防和治理相结合，以预防为主;治坡与治沟相结合，以治坡为主;工程措施与生物措施相结合，以生物措施为主。只有采取各种措施综合治理和集中治理， 持续治理，才能奏效。

a country maid was walking along with a can of milk upon her head,when she fell into the following train of reflections."the money for which i shall sell this milk will enable me to increase my stock of eggs to three hundred,these eggs,allowing for what may prove addle,and what may be destroyed by vermin,will produce at least two hundred and fifty chickens.the chickens will be fit to carry to market just at the time when poultry is always dear;so that by the new year i cannot fail of having money enough to purchase a new gown.green-let me consider-yes,green becomes my complexion best .and green it shall be, in this dress i will go to the fair,where all young fellows will strive to have me for a parter;but no-i shall refuse every one of them,and with a disdainful toss turn from them."

transported with this idea,she could not forbear acting with her head the thought that passed in her mind,when down came the can of milk!and all her imaginary happiness vanished in a moment.

美丽的森林里住着许多小动物。

空中一群群小鸟正在飞翔，其中的一群小岛正在窝里舒舒服服地说笑话。一只公鸟说：“我要当北极探险家。”母鸟说：“去到那里你准会成为鸟冰棍的。”听了这番话，公鸟气冲冲地说：“我要跟你离婚。”说完就飞走了。母鸟大喊道：“我最爱的阳光帅气的老公快快回来呀……”直到母鸟喊累了，才知道自己错了，它自言自语地说：“当初真不应该这样说呀

树上的其中一个小猴说：“想参加摘桃比赛的猴子，请到老猴子那里报名参赛。”于是，一群群的小猴子纷纷跑到老猴子那里报名。因为人多，所以报名报到了半夜呢。

这片森林可真热闹啊!

At present, the humanitys common mother - the earth, she for us, even his ill have no complaint, and we also - should take care of mother?

As long as you to the earth mothers blood - stream, the stream will find there are often animals such as in shat people littering caused the river smells like vomit. Another small fish and other animals in survival rates. The earth mothers bones, mountain is also at stake; Hair - woods also disastrous. Those who give loess to dig down, and then sell it to others with a high price. And the earth mother is brimming with his pain and fear his cry will cause floods. The birds in the trees are also being shot to death of the human race. Number is being with that sharp axe or chainsaw destroy forest.

Nowadays, people to see the earth mother in such pain also has the environmental protection consciousness. People slowly made public service ads, but also made environmental signs, but also on March 12 as Arbor Day. The villages have special sanitation workers.

And our students what to do to protect the environment? Actually very simple, we only need to bent down to pick up a pick up trash, pour a garbage, stop the mom and dad do not environmental protection, use less a chopsticks, etc.

We have only one earth, we need to protect our earth!

目前，人类共同的妈妈——地球，她为了我们，连自己生病了也丝毫不控诉，而我们也—应该关爱妈妈吧?

只要你到地球妈妈的血液——小河、小溪等就会发现经常有动物在排泄粪便，人们乱扔垃圾造成河水让人闻起来就想吐。另外小鱼等动物骤降存活几率。地球妈妈的骨头——山峰也危在旦夕;头发——树林也损失惨重。那些人把黄土给挖下来，然后再用高价卖给别人。而地球妈妈正强忍着自己的痛苦身怕自己哭泣会造成洪灾。树林中的小鸟也正在被人类的枪给打死。数目正在被人吗用那锋利的斧头或电锯破坏树林。

如今，人们看到地球妈妈这么痛苦也有了环保意识。人们慢慢地做出了公益广告，还做出了环保标语，而且还吧3月12日定为了植树节。各村都有专门的环卫工人。

而我们小学生该做什么才能保护环境呢?其实十分简单，我们只需要弯腰捡一捡垃圾，倒一倒垃圾，阻止爸爸妈妈做不环保的事情，少用一次型筷子等。

我们只有一个地球，我们要保护我们的地球!

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.
