From this cartoon, we can see that at the top end of the river,is a chemical factory and a paperrnaking factory which send out and poisonous wastes. And the river has been seriously polluted,n be seen from the color of it. Along this "black" river, there area few people selling fresh water which must have been taken from far away places.

At the first glance, it is very strange to us how can people sell water along the river, but this is the case, because the water in this river is undrinkable. This presents a serious social problem--environmental pollution. With the development of economy, our living standards have been greatly improved. But we can＇ t ignore the fact the air we take in and the water we drink today are not as fresh and clean as they used to be. Some kinds of pollution can even be deadly to people. It is high time that we took some measures to solve the problem.

I think we can first call people＇s attention to this problem so that they will be aware of the serious consequences of it. Then,we can pass certain laws to restrain the factories from sending out wastes. Finally, we can do more resarch work to find out ways to deal with the wastes.

Keep Square Clean, Tidy On Sunday, still on display on Tian＇anmen Square were dozens of floats that were paraded along Chang＇ an Avenue during the NationalDay celebrations. Thousands of people strolled on the narrow lanes be- tween the floats that fragmented the square, busily taking photos. Not far from the noisy crowds, yellow leaves fell nonchalantly from locust trees along the driveway, sending out the first signals of the coming autumn. But even if all the leaves fall, they still cannot cover the brown and black spots on the hitish stones in the huge square.

Such stains of chewing gum, stale oil or some worse blemish have remained a constant pain for city cleaners since the square ＇was re-opened a few months ago after renovations to celebrate the 50th anniversary of the founding of the People＇s Republic of China.

Few renovation project planners likely foresee this discouraging outcome. Originally, they merely intended to give the city a facelift. The square was indeed impeccable when new: The-white terrazzo surface not only looks clean but it was made with materials that help prevent it from becoming slippery.

However, as time goes by, the virtue becomes the vice: the surface attracts and accentuates dirt. As a result, China＇ s most high profile site has to suffer the indignity of being paraded daily efore thepublic in a humiliation state.

While the tourists who litter should bear the bulk of the blame, the renovation designers should also have learned something: including the square＇s sanitary maintenance issue into their consideration.

济南市环境保护委员会的叔叔阿姨们：

您们好！

暑假期间，我跟随父母去大明湖游玩，所见所闻一直印在了我的脑海里。美丽的大明湖中，荷花盛开，千姿百态，真不愧是“四面荷花三面柳，一城山色半城湖”呀！我陶醉了！但这时，猛然看见一位游客将一块糖果的包装纸扔到了湖水中，而不远处就是垃圾箱；甚至还有几位游客随手将荷叶和荷花摘去。虽然有管理人员劝说，可是他们还是满不在乎。荷叶根部漂浮的垃圾，靠近岸边的被摘去的荷花、荷叶深深地刺痛了我的心。因此，我想提出几点建议：

一、可以开展一些文艺活动，通过演出的形式来教育那些不爱护环境的游客；

二、与游客做一些小游戏，如环保知识问答等，并给予小奖品，让人们认识到环保的重要性；

三、组织志愿者每周打扫大明湖的环境卫生；

四、开展“我爱大明湖”摄影比赛与征文比赛，唤起人们对大明湖的热爱；

五、号召小学生组成义务宣传队，通过宣传为泉城尽自己的一份力量；

六、设计一个“曝光台”，曝光有些人的不文明行为。

亲爱的叔叔阿姨们，泉城是我们的家，大明湖是我们泉城人的骄傲。让我们行动起来，保护我们的家园，爱护令我们骄傲的大明湖，好吗？

金黄色，是一种幸运、光辉的颜色，曾是古代至高无上的皇家御用色。而此处的金黄色就没那么惹人喜爱了！这里黄沙满地，水源奇缺；岩石因风化而渐渐形成了独特的蘑菇状；还有迷幻无穷的海市蜃楼；只要你走进去，就像走进了永远出不来的黄色旋涡；随时随地发生的龙卷风和沙尘暴就像吃人的恶魔，如影随形。它，就是荒漠化的土地、地球的毒瘤——沙漠。

沙漠，就像潘多拉的魔盒，一旦不小心打开盖子后，就肆无忌惮地向四处抛洒着沙子，让自己的地盘日益壮大。它咆哮着绿地，吞并着水源，蹂躏着万物，且不停舒坦地伸展着肥硕的身躯，没有丝毫仁慈，一刻也不消停。它的孩子更加横行霸道，一会儿来个龙卷风，把所到之处的一切都吸进它的身体。龙卷风还可以一分为二，二分为四，它的分身术，真的很高深又迅捷；一会儿又来场沙尘暴，胆大妄为地将整片土地搅得天昏地暗、鸡犬不宁，时不时使出“佛山无影脚”。哎呀，虚虚实实的，还真会打“太极拳”，一切生物都被折磨地苦不堪言、痛不欲生。

难道我们就没有办法对付它了吗？答案是——有的！我们可以大规模引进沙漠植物，如金琥、沙棘、白杨等等，将它们植入沙地中，让它们用发达的根系牢牢锁住水土，改善土壤质量，减缓沙漠扩张，直至沙漠完全消失。

土壤是一切生物赖以生存的地方，是一切生命活动的源泉！我们人类必须停止乱砍滥伐，要珍爱绿地和土壤，多多植树造林；不能再将塑料制品或有害垃圾不经处理就置于土壤之下，请不要继续做沙漠的帮凶！

作为一名小学生，我们要从身边的小事做起，植一棵小树，种一束鲜花；减少使用一次性木制品；拒绝使用难以分解的塑料用品，真正地做一个环保小达人！

珍惜土壤，爱惜绿地，保护环境，拒绝土地沙漠化，这是我们每个公民应尽的义务！让沙漠走上不归之路，让绿色覆盖茫茫荒漠，这便是我们的终极目标！

珍爱地球，它是我们永远的家园，珍惜绿色，它是我们永远的守护神！

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 are

still 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.

在一个公园里有一条干净的小路。

一个阳光明媚的大早上，在公园的小路上人很多，我看见有好多人在草地上野餐，我走了一圈发现公园的地上，有很多垃圾，我又发现草地上也好脏，我和妈妈马上跑出了公园，在公园里的人越来越少，过了一会儿，公园没人了，我伤心地说：“妈妈，公园好嗅啊！”妈妈和蔼可亲地说：“不行，公园再这样就没有人来这玩了。”“那怎么办呀？”我伤心极了！

后来妈妈去买了个东西，妈妈给我了口罩，我们把香气的东西一个个放了进去，我把每个地方都放了一个。过了一会儿，公园香啊，我拿了袋子就进去了，我和妈妈在里面。

过了一会儿，有一个人来了，她和我们一起打扫，很快就好了，又有很多人来了，我开心地笑了。

我们就该保护环境，保住环境是我最大的快乐。

This winter is freezing cold. I didn’t have any desire to go out for play.

I always stayed at home. Actually, most of the time I was in my bed. When I felt

anxious for staying inside too long, I will go near the window to wach the

children building snowman or throwing snowballs. It seemed very interesting. But

I just didn’t want to go out. Later my mother found that I was so lazy. Then she

forced me to go out. Since my mother said, I have no excuse to reject. My mother

is right. Though the outside was icy, it’s fantastic. Everything smells fresh.

Since then, I went outside everyday, and then did my homework and felt full of

energy. The holiday ended very soon. It was a lazy holiday.

尊敬的环保局局长：

我是安阳市钢城小学六（一）班的一名小学生。这几年安阳的变化非常大。水变清了，天变蓝了，草变绿了……安阳的环境明显比原来好了，这可少不了您的功劳。不过地上还是有随处可见的白色垃圾。

当您走在街上就可以看见到处都是随处可见的塑料袋，一次性饭盒、塑料瓶。菜市场里遍地都是花花绿绿的塑料袋。饭店里，人们用塑料袋，一次性饭盒打包饭菜。冷饮店门口到处都是塑料瓶。人们把一些用完的白色垃圾随手乱扔。

我觉得存在这些问题的主要原因在于：没有加强市民的环保意识，现在，在超市里虽然买塑料袋是要收费的，但是三角，五角对人们来说已经是小得不能再小的数目了，所以还有一些不讲文明的市民去购买塑料袋。菜市场里的塑料袋是不要钱的。饭店里带饭盒去吃饭的人几乎为零，所以当人们吃不完怕浪费就要求打包带走。

减少白色垃圾的建议如下：

1、饭馆不要使用一次性筷子，尽量少得使用塑料袋与一次性饭盒。

2、商店里禁止出售一次性塑料袋，如果忘记拿购物袋，可以在商店里买可以再次利用的购物袋，也请市民在去超市之前带上购物袋。

3、在饭料外包装上写上：请勿乱扔。以此警告人们不要把塑料瓶乱扔。

为了减少白色垃圾的污染，请您能研究并采纳我的建议。

Since I was very small, my parents sent me to learn painting. They thought

I could understand art and mastered one skill. This experience brings me the

sense of art. I have my own understanding of it.

On the one hand, art is an important way to express peoples opinion. When

we see the pictures, the difference between classical and ordinary paintings

lies in the thoughts. The famous artists implant their ideas in the pictures,

which are admitted by the public, so the value of arts can be seen. Some famous

artists expressed their unique opinion and gives arts great meaning.

On the other hand, art is not only from works, but also from life. For

example, my mother cooks the delicious food. Everybody speaks highly of her. So

her food brings people great happiness, which makes the food an art for me.

Whats more, my friends is good at communicating. The way she talks can convince

other easily, so I call the way she communicates as an art.

In all, for me, art is around. It brings people a way to see the world or

makes our life wonderful.

My Views on Environmetal Protection

Nowadays, the world we live in is becoming more and more intolerable because of environmental destruction. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. Recently,haze weather has become a usual phenomenon here in large part of China. People are forced to wear the mask to avoid breathing poisonous air. Some people think it is impossible to solve the problem,however,from my opinion,if we find out the reason and take effective measures the environment can be better.

If we trace the cause for haze weather,the main points are as follows,first,our countrys air quality standards are rather lax and evaluation factors are limited,so you will see that current air appraisal system has defects. Second,some people just go for economic interests instead of turning out products according to relevant law and regulations. They tend to use obsolete equipment in which they are more likely to emit a great deal of wasted air. Third,across our society,the awareness of protecting the environment has not built up so that people havent formed a habit of using green product and saving energy as much as possible. If we dont take action to show respect to the environment, we will have to face an increasingly awful situation.

Therefore, effective measures should be taken and laws passed to conserve the environment. In my opinion, to protect the environment, the government must take even more concrete measures. First, people should be educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. Second, much more efforts should be made to put the policy of population into practice, because more people mean more pollution. Finally,laws concerning environmental protection should be put into effect and enforce strictly just as our government has been doing. To sum up,if we work together to take out such measures,our environment will get better and better and haze weather will vanish completely.

当我们从堆积如山的垃圾旁走过；当我们从乌黑如墨的河流边经过；当我们不得不每天呼吸着满是沙尘和废气的空气时，我们应该如何做？是漠然而对？还是积极的呼吁：请保护我们赖以生存的自然环境！

还记得以前上学时经过的一座桥，从桥面望下去，能看见河底的细沙，偶尔还能看到游鱼在水中嬉戏。流经桥下的清澈小河，是许多村民日常生活的好伙伴。人们在这条河里洗衣服、洗菜，兴致来了，甚至在河里游泳，捕鱼。这里也是我们童年时的乐园，自由自在的小鱼、小虾伴随我们在水中快乐的游玩，让我们的童年充满了乐趣！

然而好景不长，近两年不知从哪来的一群人，在河边建了一间工厂，工厂是生产什么的我们不知道，但这间工厂每天都用几根管子把乌黑的废水排出我们村民都喜欢、依赖的小河。村民们抗议过，但工厂的工作人员根本就不把村民的劝告放在眼里，只顾自己能多赚钱就行，面对村民的抗议，他们不管不顾，自己喜欢干什么就干什么。现在原来那条清澈见底的小河已经被那间工厂的废水污染了，昔日透明的河水变得乌黑发臭，村民们都不敢在那里洗衣服、洗菜，甚至从河里捕捞的鱼儿，即使还活蹦乱跳也不敢送进口里了。至于游泳，也仿佛成了我们的痴想！

面对态度如此恶劣的工厂，村民们没有妥协，他们积极向村委和上级有关部门投诉，并自发组织村民阻止工厂继续向小河排放污水。在村委及上级部门的干涉和村民们不放弃的努力下，工厂的负责人不得不承认了错误，承诺关闭工厂并为恢复小河原貌出一份力！

经过这一件事，村民们的环保意识都得到了加强，他们通过抗争知道面对环境的污染，如果人人都能团结起来，改变环境被污染的情况也不是不可以的。我也从这件事中明白了：地球是我们共同的母亲，她养育了我们，面对母亲所受到的污染，我们不能视而不见，无动于衷，而应该积极行动起来，用自己的热忱及努力改变这种情况。

请大家都积极的动起来，从我做起，从身边的事开始努力，保护好我们赖以生存的自然环境！

good environment can make people feel happy and fit . to improve the environment means to improve our life.

When I was very small, I lived in my hometown. My grandparents raised two

dogs, and I liked them very much. I watched them grow up from the little animals

to the big dogs. Every time when I leaved home for school, they would follow me

for some distance. When I walked a little far away, they would turn home. When I

went home after school, they would wait for me in the door and swayed their

tails. I knew they were welcoming me home. They were like my family members and

I learned that animals are part of our nature. We should protect them. We can

create a harmonious society.

Children’s education has been concerned by the public all the time. As they

are the future and will decide a country’s destiny, so the environment matters

so much to them. Most parents expect the school can provide the children a good

learning environment and ignore the importance of home education.

School provides the children a direct stage to receive education. In the

school, the teachers pass knowledge and educate them the right value. The

children know their task and as everybody around them focus the attention on

study, so they are affected by each other and have the strong desire to

learn.

Home education is easy to be ignored by most parents, they think it is the

teachers’ duty to educate children. Actually, most criminal teenagers have

family issues. Parents haven’t set good example for the kids. Sometimes they are

even the trouble makers. Without love, teenagers won’t grow up as the strong

people.

Both school and family environment are important for the children, and they

need to be nurtured with the good examples and learn knowledge.

周末，我和爸爸妈妈来到十六潭公园郊游。一路上，鸟语花香，到处充满的春天的气息路旁的柳树妹妹租着自己的小辫子，小草从土里慢慢的探出头来。

终于到了目的地，找到了一块小小的空地，爸爸铺好了一张长长的，蓝白相间的餐布，妈妈小心翼翼地拿出食物，把香蕉三明治，还有我最喜欢的鸡翅和鸡腿等等，放到餐布，我盯着我最喜欢的鸡翅，一把抢过来，闻了闻，舔了舔嘴巴，咽了咽口水，大力的撕开袋子，狼吞虎咽，然后一边吃一边说："妈妈，还有没有吃的啦！"妈妈转了身，理了理衣服，微笑的说："这里还有，小心点别噎着。”我吃完了鸡翅，留下了骨头，我都扔在草地上，骨头正好被茂盛的小草给掩盖住了，我看到了也不理睬。还继续吃，然后，吃完的垃圾袋被我一个一个的扔到的草地上，最后我四周到处都是垃圾。

忽然我看到穿着橘色的衣服的清洁工，正在那边弯着腰打扫边上的垃圾。满头大汗，伸出像树皮一样的手，走到我的旁边，先用钳子把垃圾放到垃圾箱，接着轻轻拿着扫把到处扫，然后，放进垃圾箱。最后就默默的走了。

后来我又看到一个小男孩手上提着一袋垃圾，走进垃圾箱，垫起了脚，把垃圾袋扔进去。我的脸顿时像红红的大苹果。想起老师说过，"保护环境，人人有责。”我就决定一定不能扔垃圾，要爱护环境。

地球是我们的母亲，可是近年来灾难频频发生，母亲的血液也混浊不清，母亲的毛发也快没了，现在的母亲已不是那个美丽漂亮的母亲了，地球母亲日益的衰老，而这一切都是我们造成的。

母亲一直为我们默默的奉献着，可是忘恩负义的人们让污水横流，让一些土地寸草不生，让黄沙满天，母亲终于忍不住这种痛苦了，一向温文尔雅的地球绝了食。

这下好了，农作物颗粒不收，山洪。泥石流。地震。海啸。赤潮一个接一个的来了，人们终于意识到了保护环境的重要性。可是有些事不可挽救的了，虽然为时还不晚，可是如果到了地球马上要毁灭时的最后一滴水将是人类的泪水。

赤潮是我认为最危险的灾难，当然赤潮的诞生还要多亏了人类。赤潮也称红潮，赤潮是在特定的环境下，海水中的浮游植物。原生植物和细菌爆发性增殖或高度聚集在一起而引起水体变色的一种有害的生态现象。赤潮是一个历史沿用名，他并不一定是红色。

“赤潮”，被誉为“红色幽灵”，国际上也称其为"有害藻类"，赤潮是海洋生态系统中的一种异常现象。它是由海藻家族中的赤潮藻在特定的环境条件下爆发性繁殖造成的。海藻是一个庞大的家族，除了一些大型海藻外，很多都是非常微小的植物，有的是单细胞植物。根据引发赤潮的生物种类和数量的不同，海水有时也呈现黄、绿、褐色等不同颜色。

一是大量赤潮生物集聚于鱼类的鳃部，使鱼类因缺氧而窒息死亡；

二是赤潮生物死亡后，藻体在分解过程中大量消耗水中的溶解氧，导致鱼类及其它海洋生物因缺氧死亡，同时还会释放出大量有害气体和毒素，严重污染海洋环境，使海洋的正常生态系统遭到严重的破坏；

三是鱼类吞食大量有毒藻类。

赤潮发生后，除海水变成红色外，同时海水的pH值也会升高，粘稠度增加，非赤潮藻类的浮游生物会死亡、衰减；赤潮藻也因爆发性增殖、过度聚集而大量死亡。

赤潮是在特定环境条件下产生的，相关因素很多，但其中一个极其重要的因素是海洋污染大量含有各种含氮有机物的废污水排入海水中，促使海水富营养化，这是赤潮藻类能够大量繁殖的重要物质基础，国内外大量研究表明，海洋浮游藻是引发赤潮的主要生物，在全世界4000多种海洋浮游藻中有260多种能形成赤潮，其中有70多种能产生毒素。他们分泌的毒素有些可直接导致海洋生物大量死亡，有些甚至可以通过食物链传递，造成人类食物中毒。

善待地球就是善待自己，拯救地球就是拯救未来，这世界都是有因果关系的，种下善良就会得到回报，种下恶果就会得到报应。解铃还需系铃人嘛，停止吧快去拯救我们唯一的住所地球吧！！

With the rapid development of science and technology, human demand for resources is increasing, causing the Antarctic arctic ice melting speed, rising sea levels, the Antarctic ozone hole, increasing dust storms in Beijing, haze weather, the Japanese earthquake nuclear pollution...

When we enjoy the good life at the same time, the thought of the importance of protecting the environment?

随着科技的高速发展，人类对资源的需求越来越多，致使南极北极冰雪融化的速度加快、海平面日渐上升、南极出现臭氧空洞、北京的沙尘暴、雾霾天气不断增加、日本大地震后造成的核泄漏污染……

当我们在享受美好生活的同时，是否想到保护环境的重要性呢?

那么，请同学们关注一下我们的校园，看!操场上、校门口、楼梯过道上漫天飞舞的纸屑、食品袋、饮料瓶;瞧，雪白的墙壁上那些张牙舞爪的涂鸦……这些都是和我们校园文明不和谐的一幕啊!

同学们，如果我们大家都行动起来，争当环保的主人翁，不乱扔纸屑、果皮，不乱涂乱画，随手捡起地上的纸屑垃圾，爱护环境，把我们的校园装扮的漂漂亮亮。当我们在绿树成荫的校园小道上漫步时，一定会感到心旷神怡;当我们在窗明几净的教室里读书时，一定会全神贯注;当我们在整洁优雅的环境中学习时，一定会心情舒畅。

优美的环境，让我们懂得珍惜，学会爱护;优美的环境，让我们知书达理，更加文明;优美的环境，让我们学会谦让，学会做人;优美的环境，让我们道德高尚，使我们的学习更加进步!

湛蓝的天空上，不时有鸟儿飞过。四周是漫山遍野的绿色，青翠欲滴，仿佛一片绿色的海洋，即将要流入你的心中。森林里，各种各样的动物在互相嬉戏，享受着这美好且和谐的大自然……这，是曾经的地球。

可是如今的地球却与曾经相差如此遥远。绿色在迅速消失，天空也不再蔚蓝，动物们更是我家可归，一切都源于我们人类，而现在，作为罪魁祸首的我们也该为地球做点什么了……那一天，辅导班组织“绿色家园”植树活动，每一个人都积极参加，乘着大巴车，来到了一片开阔的平原上，这里没有一棵树木，有的只是遍地的杂草。每个人都从车上拿下了自己的树苗，我也不例外，植树，说起来简单，做起来却困难得很。首先，我们要除去这里的杂草，以便影响树苗的生长。每个人都拿起了从没摸过的锄头，便热火朝天的干起来。因为是第一次干活，当笨拙的我们将在草出完的时候，已经是烈日当空了。这仅仅是第一步，大家就累得上气不接下气，我也不例外，坐在地上再也不想站起来了。但是，我们没有放弃，每当想到曾经的地球是那样的美丽，我们就感到浑身充满了力量。在老师的带领下，我们齐声嘹亮地唱着歌曲为自己助威，挖坑，植树，浇水，大家热火朝天地干着，终于，在夕阳西下之前，完成了工作。这次活动之后几天之内，我的身体都酸痛的没有力气，但是我的心里却乐开了花，能够为保护环境出一份力，是每个人的荣幸。

各种事实证明，只要人们肯去努力，都能够团结起来保护地球的环境，其实，曾经的地球离我们并不遥远。以后的生活中，我还会去积极参加这样的活动，也希望能够有更多的人加入进来，一起为我们的地球母亲恢复原来的容貌。

本校全体师生们：

你们好！

现在大街上都是随处可见的垃圾。有的被风吹得满天都是，有的被风吹到了河中，还有的吹到了居民家的院子……有一些人不仅乱扔垃圾，还随意破坏大自然的花草树木，使它们不能再生，丢掉生命。这些现象已经严重毁掉了我们的生活环境，因此，我在此发起倡议：

一、不在大街上丢垃圾。丢垃圾这样不仅破坏了大街上的环境，还给年纪大的老爷爷和老奶奶带来了麻烦，影响出行。

二、野餐时要带走自己带来的垃圾，不能随意被五颜六色的垃圾盖住了。既污染环境，还破坏了绿草以及植物生长的土质。

三、不往河中排放废水（污水）。这样既破坏了水质，还让水中的鱼儿们死亡，更给常年住在河边的居民带来了非常大的不便。

四、节约用水。大家都知道水是生命之源，由于人们浪费水资源，有一些地方已经干旱。那里的人们因缺水而死亡。

五、不用一次性东西。有些人经常点外卖，造成一次性筷子的大量使用，这使大自然的树木不断减少。

六、不把垃圾扔进河里。有一些人经常把垃圾扔进水里，这一些垃圾随着水流漂进海洋变成了“海洋垃圾”，出海的渔船发动机经常失灵。

在这我倡议大家保护环境，不破坏花草树木，垃圾要进行分类。在各个街道多安装垃圾桶，让我们行动起来，一起保护我们的家园吧！

Recently, a Chinese student who studied abroad delivered a speech at the

graduate ceremony. Her speech soon became the hot issue, because she criticized

Chinese air pollution, which was a great threat to her health. Though her speech

had exaggerated the problem, it is true that China has faced many pollution

problems. The haze in Beijing is famous around the world, which is the

punishment for human to ruin the environment. It needs time to fix the problem,

but there is no need to deny our country. Even for the developed countries, they

have once faced such problem before. We can do something in the daily life to

protect it, such as do not throw away the rubbish.
