In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

Suddenly, it saw an intruder -- a lumberjack, and was holding a pair of wood chopper in cut down a tree, and idly smoking a cigarette. "Snapping" 1, cigarette butts havent put out was he ruthlessly fell to the ground. Didnt he dont know, put out the cigarette may cause a fire?

森林里，树木成群，百花盛开。啄木鸟像往常一样，停在一棵树上东啄啄，西啄啄，在给大树治病。

突然，它看见一位不速之客——一位伐木工人，正拿着一把柴刀在砍树，一边还悠闲地抽着烟。“啪嗒”一声，烟头还没熄灭就被他无情地摔到了地上。难道他不知道，没熄灭的烟头会引起火灾吗?看着他目不转睛，两眼放光的样子，一定看见了许多钞票朝他飞来了吧!啄木鸟气愤的暗想道，顿时升起了一股无名之火!啄木鸟飞快地飞到那个伐木工人的背上，用尖尖的嘴巴啄他的脑袋。一边啄，一边暗想：看来槐树爷爷的话真没有错，人类的脑子里真的有“贪婪虫”!要不然，干嘛砍树呢?干嘛破坏资源，干嘛破坏环境呢?干脆，做做善事，给这段木头治治病吧!那位伐木工人突遭啄木鸟袭击，一时没反应过来，愣了一下便飞快地扔下柴刀捂着脑袋就跑了!

透过这幅漫画，透露出了人的无穷无尽的贪婪和欲望。借着这幅漫画讽刺了人类，告诫人们要珍惜资源，保护环境!是的!雨果曾经说过，让风沙不再猖狂，换地球一片绿色铺垫!人类破坏了自然环境，也受到了应有的惩罚，沙尘暴，泥石流，干旱，洪水泛滥等数不清的自然灾难接踵而来。造成了无数人的牺牲，是人类应受的。

带着欢乐舞步，让风沙停止，让小鸟起舞，让绿色腾飞吧!

Harmony with the environment is that we live in on Earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and the mountains on Earth, the animals. Plant human cells, if it damaged, destroyed nature organizations, to the eradication of mankind. Therefore, the environment must be linked with social ethics, character education and practice acts as an important element of it. Everyone must fulfil its responsibilities and obligations to protect the environment.

人与环境是和谐相处的，我们生存在地球上，人是自然之子，而不能仅把人看作自然的征服者，大家都知道，人类只有一个地球，地球上的山山水水、动物。植物是人类的细胞，如果我们把它损坏了，破坏了大自然的组织，等于消灭人类。因此，环境要与社会公德联系起来，与实践行为作为人格教育的一项重要内容来抓。每个人都要履行保护环境的责任和义务。

With the improvement of peoples living standard, people more and more do not take the protection of the environment, throw rubbish everywhere and spit everywhere.

Whenever I see garbage on the ground, I will be deeply touched, protect the environment, starts from me. Take the a small river near my house, for instance, in the past, the water in the river is very clear, like a bright mirror, can see clearly the many stone in the river; You can see fish free in swimming in the river. There are often many children playing, playing in the river water; The adults in the river to wash the dishes, washing clothes. Gradually, people then throw the garbage into the river, sewage discharge into the river, make the river as well as smelly and dirty, can no longer on the bottom, into a murky waters of the bin. Serious environmental pollution, serious harm peoples health. Yes, only set up the idea of protecting the environment, have a better tomorrow.

On Sunday, I find to my good friend small good, each with a plastic bag, pick up the trash in the river one by one to light, our hands are full of bags, is really "to eat"! Even if we pick up the trash in the river, but you cant stop the garbage in the river, get off there will be, how to do? The most critical or arouse peoples environmental consciousness, we took a plank on the plate is greatly write: please protect the environment, starts from me. We put it in the river, in a prominent place in the task is complete, we are pleased to go home.

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。

为了保护我们自己的家园，为了保护我们自己的生命，为了我们自己的将来，为了我们美好的环境，让蓝天更蓝，让清水更清，让地球妈妈更可爱，更生机勃勃，让我们张开小手，献一份爱，出一份力，共创绿色的环境。

Some people believe that economic development should never be at the cost of the environment.They think the present serious environmental problems are largely caused by rapid?economic development.For example,land resources are shrinking because of the industrial development and the expansion of cities.Deserts are spreading because of over grazing,poor fanning,tree cutting,and strip mining.Our air and water supplies are being polluted by poisonous gassesand waste products.It is important,therefore,that we should take another look at the way in which our industries and cities are developing.

However,other people think it unnecessary to consider environmental problems now and our first priority should always be given to economic development.They believe that environmental problems are inevitable and unavoidable in the process of economic development.They are only the by products of economic development,which can be dealt with later when we have the time and money.

I think the second idea is completelywrong.Our ultimate aim in economic development is to provide a comfortable and happy life for our people.What is the point of economic development if we achieve it at the cost of our environment?There has been much evidence to prove that a balance between the two helps more rapid and continuous development.

Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful.It is really a pity to see all this in our school.Some students don’t respect their teachers or parents. Some don’t take their studies seriously and cheat in exams. Some throw wastes everywhere and pollute the environment . It is honorable to obey the law and rules , care much about our class and study hard.It is shameful to break school rules, to be selfish or to make little effort to achieve success.We should respect others and think more of them than of ourselves.We should work hard and make much more progress to repay the society.We should try our best to keep the environment clean。

With the improvement of our living standard， more and more people can afford a car。 As a result， our roads are more often than not crammed with cars。 However， with more and more waste gas being discharged by the cars， the problem of air pollution bees even more serious。 So nowadays we advocate to lead a low-carbon life。

My suggestion is we should ride bikes more often instead of driving cars。By riding a bike， we can not only exercise our body but also protect our environment。 Why not have a try， my dear friends?

Everybody is responsible for environmental protection,. I accidentally caught a cold, do not know why, so he went to see the doctor, my mother asked the "flu?" Asked his mother.

The doctor shook his head, said: "because there are too many viruses in the air, is full of garbage, house dust, industrial emissions, and so on, these are the cause of poor air quality, virus." I seemed to understand a lot.

With the development of the society, living standards continue to improve, we drink the tap water, use the TV set, refrigerator, heater, elevators, etc. But in life, we constantly in the waste of resources, clean water, watering the flowers in the water, washing water, waste every day. Water for us to be of much use, irrigate farmland water, building water, plants and trees need water, and peoples life water for industrial water, we cant live without water. However, as we waste water was contaminated. If we use wash bowl of water to water the flowers and clean the water to wash clothes, wash your hands when the water is boiling down a little, that how much we want to save water. Electricity, as usual, we open a lamp less per person a day, watch less TV for an hour, less a elevator, how much we want to save electricity. When we are standing on the street, smell the stench, walking in the street is full of garbage, look up at the sky gray, one after another car emissions both in the exhaust, and people in disorderly cut down trees? Observe, to think of it, our environmental protection consciousness is so bad.

Nature cannot be improved, the life can choose to choose green, environmental protection, everybody is responsible for.

环境保护，人人有责。 我不小心感冒了，不知道是为什么，于是就去看了医生，妈妈问这“是流感吗?”妈妈问。

医生摇了摇头说：“因为空气中有太多的病毒，到处是垃圾，修房子的灰尘，工业排放的废气等，这些都导致空气质量差、病毒多的原因。”我似乎明白了很多。

随着社会的发展，生活水平不断提高，我们喝上了自来水，用上了电视机，冰箱，取暖器，电梯等。但生活中我们不断地在浪费资源：打扫卫生的水，浇花的水，洗衣服的水，每天都在浪费。水对于我们有多大的用处，浇灌农田要用水，修建房屋要用水，花草树木需要水，还有人们的生活用水工业用水等，没有水我们就无法生存。然而水在被我们浪费，被污染。如果我们用洗碗的水来浇花，洗衣服的水来打扫卫生，洗手时水开小一点，那我们要节约多少水。电也一样，我们每天每人少开一盏灯、少看一小时的电视，少座一次电梯，我们要节约多少电。当我们站在街上，闻到的是臭气，走在大街上到处是垃圾，抬头看天空灰蒙蒙一片，一辆接一辆的汽车都在排放着尾气，还有人在乱砍伐树木?注意观察，仔细想想，我们的环保意识实在太差了。

自然不可改良、生活可以选择 选择绿色生活、环境保护，人人有责。

Economic development and environmental protection are a pressing issue primarily for developing countries where, in trying to catch up with developed countries, they have to consume natural resources on an unprecedented scale. This has seriously polluted our environment and, with the global environmental campaign gaining momentum, many people in China call for the precedence of environmental protection over economic development.

Any attempt to pose economic development and environmental protection as diametrically contradictory is simple-minded. Since no country is willing to stop its economic development, the best way is to strike a balance between the two and to heighten the environmental awareness of those solely concerned with economic development.

European countries both economically developed and environmentally friendly can serve as perfect examples for China. Their success story in both undertakings illustrates that environmental protection does not mean a complete standstill of economic activities or exploitation of natural resources, but rather an active development and application of effective technologies to minimize environmental consequences. In Germany, environmental protection has become part of economic development as it boasts the world s most successful environmental industry. With a developed economy, we are well equipped to develop sophisticated technologies that can effectively safeguard our environment.

[英语作文：经济发展与环境保护

The survival of the earth is our home, its like mother, provide us with the resources and conditions of survival. We are the master of the earth, we should like to yourself to protect it.

Who wouldnt want to make their homes more beautiful, more beautiful? However, with the development of science and technology, more and more living garbage all sorts of multifarious, including most waste will cause environmental pollution. For example we commonly used battery, if you dont properly handle after use, it will cause a great environmental pollution. According to research, section button battery waste 600000 litres of water undrinkable. If each throw away a battery, then then, water, and will become a luxury.

So, in order to protect the environment, please put garbage sorting.

On June 1, 2008 in our country implements the "plastic limit order", the practice, to make our country save thirty-seven million barrels of oil a year. Plastic bags, this kind of thing for ordinary family ordinary but again, but you know, plastic bags is one of the main factors pollute the environment. Plastic bags with oil as raw material, not only consumes a large amount of resources, but also need 500 years to be natural decomposition.

So, in order to protect the environment, use less plastic bags, please.

As the owner of the society, to improve the earths environment, it is our duty-bound responsibility and obligation. If the world environmental protection, environmental protection, everyday everyone can create a new, beautiful world!

地球是我们赖以生存的家园，它就像母亲一样，为我们提供着生存的资源和条件。我们是地球的主人，我们要像善待自己一样去保护它。

谁不想让自己的家园变得更美好，更漂亮?然而，随着科学技术的发展，各种五花八门的生活垃圾越来越多，其中大多数垃圾都是会造成环境污染的。比如说我们常用的电池，如果用完后不进行适当的处理，那么将会造成极大的环境污染。据研究，一节废的纽扣电池能使60万升的水不能饮用。如果每人丢弃一颗废电池，那么到了那时，水，将成为奢侈品。

所以，为了保护环境，请将垃圾分类。

我国于2008年6月1日起实行“限塑令”，这一做法，使我国每年节省三千七百万桶石油。塑料袋，这种东西对于普通家庭来说再普通不过了，可是你知道吗，塑料袋却是污染环境的一大因素。塑料袋以石油为原料，不仅消耗了大量资源，而且还需要500年的时间才能被自然分解。

所以，为了保护环境，请减少使用塑料袋。

c. your composition should

1. 人们认为淡水是取之不尽的（提示：雨水，河水，井水）

2. 实际上淡水是短缺的（提示：人口增加，工业用水增加，污染严重）

3. 我们应当怎么办（提示：节约用水，开发新水源）

例文： global shortage of fresh water

people often think that water will never be used up. there is plenty of water, such as rain, water from the rivers and wells. it seems as if water is always available around us and we never have to worry about water shortage.

in fact water is rather limited on the earth. with the rapid increase of population and fast development of industries, water is more needed than before. at the same time, a large amount of water has been polluted and wasted every day. some big cities in china are facing the problem of water shorage already. there, water supply is controlled and industry has been restrained.

what should we do about the water shorage? i think, first, the people should be made aware of the real situation about the water. everyone should consciously save on water and certain law should be made that no water will be polluted. we have to protect the existing water resources and develop new ones. in this way i believe that our cities will not be thirsty for water in the future.

I wonder if the students have seen a picture of the comic, the title is "the fish also needs protection", "on the surface of the floating many trash, some heavier continues to sink. A little fish in the water with a lotus leaf. This seemingly funny cartoon has deep meaning.

Although only a usual cartoon. Have you ever thought, in a few years, decades, hundreds of years... Will become a reality? According to the survey, 20% of freshwater fish endangered, 50% of the coral reef degradation. About two thirds of the population in 2025 water supply difficulty... All kinds of ugly data show that the earth, homeland of human suffering from the tremendous harm. As human beings we must stand up face, start from every little thing. Such as: protect the environment, and actively promote civilization.

Hugo said: "mother nature is good, is also cruel butcher." If you dont protect the environment, so, the plants and trees might be people watch exhibits. Because trees reduce, originally all over the world every year about 300, one hundred million tons of soil erosion is not even more in the future? At that time, the earth can also give us the wealth?

To their homes, for ourselves, for the benefit of future generations, protect the environment, everyone duty, urgent!

不知同学们是否看过一幅这样的漫画，标题是“鱼儿也需要保护”，“在水面上漂浮着许多垃圾，有的比较重的还在不断的往下沉。一条小鱼撑着荷叶在水中游。这幅看似可笑的漫画却含义深刻。

虽只是一幅平常的漫画。可你是否想过，再过几年、几十年、几百年……是不是会变成现实呢?据调查，20%的淡水鱼濒临灭绝，50%的珊瑚礁退化。大约在2025年三分之二的人口面临供水困难……各种不堪入目的数据都表明，地球——人类的家园正遭受着巨大的危害。作为人类的我们必须站起来面对，从每一件小事做起。比如：保护好周围的环境，积极宣传文明。

雨果说过：”大自然是善良的慈母，也是冷酷的屠夫。“假如你不保护好周围的环境，那么，花草树木也许就会成为人们观看的展品。因为树木的减少，原本每年全世界的土壤流失约300多亿吨，以后不就更多了吗?到时候，地球还能给予我们财富吗?

为了家园，为了我们自己，为了造福子孙后代，保护环境，人人有责，刻不容缓!

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.

Good afternoon, everyone!

We are studying in this school, and it is our duty to keep it clean and tidy. It’s not good to spit in public places, such as in the school library, in the classroom, etc. We should neither draw pictures on the walls nor throw rubbish here and there. I think we must make it a rule to do some cleaning every day. If everyone tried his best to do something useful for our school, I’m sure it will be more and more beautiful.

That’s all. Thank you.

环境保护雅思英语作文

You should spend about 40 minutes on this task.Write about the following topic:

The earth is being filled with waste material such as plastic bags and other rubbish. Is this really happening? What are some solutions to this problem?

Gives reasons for your answer and include any relevant examples from your own knowledge or experience.Write at least 250 words.

model answer:

Over the past few decades, the increasing amount of industrial wastes and household garbage has become a major problem in many countries. People have questioned what caused this problem and what can be done to improve the situation. In my opinion, two of the most critical causes of this waste material problem are the increased consumption and a shortage of space for landfill.

To begin with, modern lifestyle has contributed greatly to the increasing amount of waste and garbage we produce everyday. In other words, we have turned into a materialistic and mass-consumption society where we use more and throw away more than ever before. Moreover, countries are running out of space to store garbage and waste material. In fact, securing land for waste disposal raises controversies in many countries.

To solve this intractable problem, every citizen needs to participate in producing less garbage. For example, we can bring our own personal shopping bags instead of using plastic bags provided by stores and shops. Besides, the government can enforce stricter laws on companies to use biodegradable packaging or use recycled material. Indeed, this alone can eliminate much of the waste which is sent to at land fills. Companies can also contribute by developing new raw material which is recyclable and will ultimately lead to less garbage. One good example of this is that tire companies develop new tires for cars which are not made of rubber but of new biodegradable material.

As discussed above, individuals, business and the government can share the responsibility to reduce the amount of waste material and to save the earth. I hope that in the future our offspring will be better off with the well-preserved environment.

环境保护雅思英语作文

Environmental hazards are often too great for particular countries or individuals to tackle. We have arrived at a point in time where the only way to lessen environmental problems is at an international level.

Environmental problems have reached such proportions that people feel international organizations must be set up to intervene in world affairs to resolve these problems. Whether this will resolve the problem is very unlikely as international organizations are just an extension of human behavior. That is, if human conflicts cannot be resolved at home, then they are unlikely to be resolved at the international level. Nevertheless, international organizations do attract attention to the growing problem of aims of the international community to resolve the issue of environmental pollution and support their cause, I do not believe it is the best or only way to protect the environment; in fact, it is only a small part of what is needed in a global initiative.

All world problems, whether it is environmental pollution, war, energy insufficiency, or famine, arise from the abusive behavior of all individuals. Therefore, the solution to all these problems is the need for a collective consciousness. What is meant by this is that each individual must be aware of the impact he or she has on the world and their unique part to play in this world. After all, if one is happy with his life, he will surely not endeavor to harm the environment or anyone else. His behavior will be that of a responsible individual.

What is needed, therefore, is education. Education is the key to all problems and it starts from pregnancy all the way to adulthood and beyond. Furthermore, education means that children all over the world should be allowed to go to schools with good teachers and where teaching materials and methods can be adapted to each individual. Education means raising children to be responsible individuals.

This may sound like utopia, but it is not: if a country had important problems in its educational system, then it should realize that it is contributing to the worlds problems. These are perhaps long term solutions, but they are more realistic solutions than setting up yet another international organization.

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。

Living in a city has both advantages and disadvantages. It is often easier to find work. There are always many choices of public transport. Besides, there are a lot of interesting things to do and places to see. You can eat in good restaurants, visit museums, go to cinemas and go to parks whenever you want to relax. However, living in a city is often very expensive. You must find a well-paid job, otherwise, you will not be able to afford the things you will do. Whats more, the city is always crowded, noisy and dirty. It is very difficult to find a good place where people can enjoy peace and fresh air as in the countryside.

Environmental protection is not a new question for us, our government has put forward clear governance objectives. As every ordinary people in real life, although not may be directly engaged in environmental protection work, but we can starts from the minor matter, starts from me.

When see the bathroom faucet is dripping, close is able to raise your hand? When the battery after use can be classified collection processing and not carelessly throw away? Whether consciously or the use of ultra-thin plastic bags when shopping? Them are very small, but it reflects how much we have environmental protection consciousness.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save 17 big tree. Recycling waste 20 boxes can create a beautiful pen container. Recycling one glass bottle to save energy, can make the bulb light for four hours. Recycling one aluminum can is to save the half oil cans. So we should place the garbage classification, reproduction by the relevant department after recycling reuse!

As long as we start from oneself, starts from the minor matter, everybody joint efforts, perseverance, we will be for the society, also a piece of clear water, blue sky for yourself, I hope everybody can voluntarily protect the environment, to make our environment more beautiful life.

环境保护对我们来说并不是一个新问题，我国政府也早就提出了明确的治理目标。作为现实生活中的每一个普通人，虽然不可能都直接从事环保工作，但我们完全可以从小事做起，从我做起。

当看到洗手间的水龙头在滴水时，是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?一件件小事虽然都很不起眼，但却体现我们究竟具备了多少环保意识。

回收1吨废纸可再造出800千克好纸，可以挽救17棵大树。回收20个废餐盒可以造出一个漂亮的笔筒。回收一个玻璃瓶节省的能量，可使灯泡亮4个小时。回收1个铝罐就等于节约了半个铝罐的石油。所以我们应将垃圾分类安放，由有关部门回收后再生产再利用!

只要我们从自己做起，从小事做起，大家共同努力，持之以恒，就一定能为社会、也为自己留下一片碧水蓝天，我希望人人都能自觉保护环境，让我们的生活环境更加美好。

在我们的生活中存在着许多环境危机，今天我就略举一二。

我家隔壁马叔叔特别喜欢钓鱼，而且是钓野生鱼。那一次他去钓了几条寸把来长的小鱼回来，丢给小猫吃，结果小猫只吃了两条小鱼便躺在地上不动了。我和邻居家小妹妹一起叫小猫，可小猫躺在地上一动不动，我和小妹妹跑到它身边它也没感觉，后来马叔叔一看，原来小猫已经死了。小猫剩在食盘里的小鱼连苍蝇都不叮，我们一看，鱼鳃是绛紫色的，小猫是被毒死的。原来马叔叔钓鱼的那个小水塘早被污染了。

昨天晚上，我和妈妈从厂里一直走到西岭，中间大约有五公里的路程，我们走得很辛苦。可我抬头一看，天上飘着彩色的烟，看起来很吓人。我问妈妈那是什么，妈妈说那是附近化工厂排出的浓烟。那烟好像比空气重，一会儿就飘散在我们周围。我闻着直恶心，拉着妈妈赶快走，可等我们走出烟的笼罩，我的白衣服已经是红一片紫一片的了。

我们厂外面有几座小丘，小丘上光秃秃的什么也没有。听老爹说，那些小丘上以前都是树，但是后来被人砍了。可这一砍不打紧，一刮东南风，我们厂就闹沙尘暴。沙子吹进眼睛里，怎么都弄不出来，难受死了。

我们身边的“环境危机”还有很多，我不用多说，大家都知道。大家可以想想，这些危机都威胁着我们的健康，大家应该做到心中有数，加以制止才行啊！
