Tourism is becoming increasingly important to many countries but it also has its disadvantages.What are some of the problems of tourism?

First of all,tourism can ruin the environment.Another aspect is cultural,as sometimes foreigners show no respect for national traditions.In addition,it causes the price of everything rising.

In a word,tourism is very important,there are a lot of advantages about it,but we also should remember that there are always two sides of everything,but I believe the advantages and disadvantages of tourism can be in balance if we all become more attentive to each other and the world around us.

Today is Saturday. Today is very strange, very special, because when I go

and emission reduction, global warming, improve the environment effect. Really

To improve the earth - our homes and not so easy. An hour out unwanted

light can achieve? Not that things are not so simple. Want to save our beautiful

home, must pay more attention to the ecological environment and save the earth

cellphone. Take my brother for example. He carries cellphone all the time, no

matter what he does. When we are talking to him, he just lows down his head and

says yes, I don’t think he is listening to us. When he is walking on the street,

he still keeps his eyes on the screen. My brother is a typical cellphone user, I

feel pity for him because he misses so many beautiful moment.

to check on the cellphone. They don’t have the real communicate with others, it

is not a good behavior. It is better to drop down the cellphone and see the

scenery around us.

我们今天的英语作文也许解决不了国家大事，却可以帮助我们增加对于环境保护的意识。下面是小编带来环境保护英语作文，希望对大家有帮助。

环境保护问题英语作文篇一

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

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.

环境保护问题英语作文篇三

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

I love my school so much, because of the beautiful environment. The first

day I walk into the school, I am very impressed by the green trees and the

colorful flowers. It seems that I just walk into a park and get lost in the

green world. The trees and flowers make me feel so comfortable, and my heart

feel the peace.

Stress comes in all shapes and size, and has become pervasive, it seems to

penetrate everything and everybody, its hard to get through a day without

hearing or reading something about stress. Some doctors refer to stress as some

kind of new plague天灾, 灾害, 祸患. However, numerous surveys confirm that the problem

has progressively risen since the 1980s. Why all the disorder? After all, stress

has been around since Adam and Eve were in the Garden of Eden, Stress is an

unavoidable consequence of life. Without stress, there would be no life.

However, just as distress can caw disease, there are good stresses that balance

this, and promote wellness.

环保作文:全体少先队员：

环境问题一直倍受人们的关注，因为环境的好坏直接影响着人们的学习、工作、生活。为了保护环境，我们建议全体少先队员立即行动起来，做到以下几点：

一、全体少先队员，利用课后、课余时间开展“爱鸟护蛙”活动。因为鸟类是人类的朋友，如果见到有人买卖小鸟、鸟蛋或青蛙的话，我们要尽力阻止或上报有关人员。

二、不要随地乱扔果皮纸屑，不随地吐痰。如果见到有人随地乱扔果皮纸屑，或随地吐痰的话，我们要加以阻止和劝告。

三、水是宝贵的，我们要珍惜每一滴水。现在，我国的部分地区缺水严重，这直接影响了环境，我们要从自己做起，从身边的小事做起，节约用水。

四、我们要爱护花草树木，不乱摘花朵，不乱踩草皮，不在树杆上乱写乱画，要保护大地上的一花一草。

五、我们要植树造林，多种一些花草树木，既美化环境，又净化空气，真是一举两得。

为了保护环境，保护大自然，大家一起行动起来吧！

The classmates, you might think a little convenience bag, no pollution, this you are wrong. A small convenience bag can also be water pollution.

In every household in baicheng almost a year in more than 100 convenience bag. If only more than 100 households in baicheng, convenient to use every year about ten thousand bags. We think about lets light has 100 households in baicheng? At school, I have to take a fruit every day. But the fruit of the outer packing is a small plastic bags which convenience bag to the environment pollution is very serious. And we generally just one-time use it. Used the bag into the junkyard. But most have been put into our nature.

I want people to use less some convenience bag to bag and reduce the white pollution, please take good care of our home, save the earth mother to live!

同学们，你们可能都认为一个小小的方便袋，没有什么污染，这你们可就错了。一个再小的方便袋也能污染水源。

在白城市每户人家差不多一年就能用100多个方便袋。白城市要是只有100多户人家，大约每年都要使用一万个方便袋。大家想想咱们白城市光有100户人家吗?在学校上课时，我每天都要随身带一种水果。可是水果的外包装是一种塑料做的小食品袋这种方便袋对环境的污染十分严重。并且我们一般只会一次性使用它。用过的袋子就进了废品收购站。但大部分却被弃入了我们的大自然当中。

我希望人们少用一些方便袋改用一些布袋，减少一些白色污染，请大家爱护我们的家园，救救生存的地球母亲吧!

There is nothing complicated about eating a proper diet. For good health,

eat a variety of foods. Do not eat the same foods day after day! Foods should be

selected everyday from each of basic four. They are the four groups of food

essential to proper nutrition: the milk group, meat group, vegetable-fruit

group, and bread- cereal group, Your body will then be supplied with all the

nutrients it requires; they are water, minerals, carbohydrate, fats and oils,

proteins, and vitamins. A persons diet is determined by his attitudes, likes

and dislikes. If you eat foods from each of the basic four groups each day, you

will have a balanced diet.

Environmental protection, there are many problems at present. The most serious problems is the serious pollution of air, water and soil. Air pollution is very harmful to human health. Polluted water causes pain, resulting in death. Whats more, with the rapid expansion of modern society, vegetation greatly reduced.

In order to protect the environment, governments have done a lot of work. Adopted legislative measures to control air pollution, to protect forest resources and Marine resources and to stop any environmental pollution. Therefore, in todays government plays a most important role in environmental protection.

My view is that, in order to protect the environment, the government should take more concrete measures. First of all, should by the methods of education make people fully realize the importance of environmental protection. Second, should be more efforts to put the family planning policy into practice, because more people means severe pollution. Finally, to severely punish those who intentionally damage the environment. That they damage the environment is the destruction of man himself.

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。

为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。

我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。

中考将至，环境保护成为一个热门话题，下面是小编整理的关于保护环境的英语作文，希望对你有帮助。

Let’s Do Something to Save Our Environment

It is recently reported that some rivers and lakes have dried up in South China. A lot of fishes died. The bottoms of the rivers and lakes have become grass land. The water is becoming less and less because of the bad weather.

So everyone should do something to save our environment. First, we should save every drop of water, such as turning off the taps after using it and recycling the water. For example, we can water the plants and clean the rest room with our used water. Second, we should save energy, such as less turning on the lights and turning off the lights when we leave;Do more walking, more bicycling and less driving and so on. Third, we should ask our government to control the pollution from the factories.

Let’s act now from everything to save our environment. Don’t let our tears be the last drop of water in the world!

There was a man who had four sons. He wanted his sons to learn to not judge

things too quickly. So he sent them each on a quest，in turn，to go and look at a

pear tree that was a great distance away.

The first son went in the winter，the second in the spring，the third in

summer，and the youngest son in the fall.

When they had all gone and come back，he called them together to describe

what they had seen.

The first son said that the tree was ugly，bent，and twisted. The second son

said no - it was covered with green buds and full of promise.

The third son disagreed，he said it was laden with blossoms that smelled so

sweet and looked so beautiful，it was the most graceful thing he had ever

seen.

The last son disagreed with all of them;he said it was ripe and drooping

with fruit，full of life and fulfillment.

The man then explained to his sons that they were all right，because they

had each seen but one season in the tree‘s life. He told them that you cannot

judge a tree，or a person，by only one season，and that the essence of who they are

- and the pleasure，joy，and love that come from that life - can only be measured

at the end，when all the seasons are up.

If you give up when it‘s winter，you will miss the promise of your

spring，the beauty of your summer，fulfillment of your fall. Don’t let the pain of

one season destroy the joy of all the rest.

当前，威胁人类生存的十大环境问题是：

(一)全球气候变暖

由于人口的增加和人类生产活动的规模越来越大，向大气释放的二氧化碳(CO2)、甲烷(CH4)、一氧化二氮(N2O)、氯氟碳化合物(CFC)、四氯化碳(CCl4)、一氧化碳(CO)等温室气体不断增加，导致大气的组成发生变化。大气质量受到影响，气候有逐渐变暖的趋势。由于全球气候变暖，将会对全球产生各种不同的影响，较高的温度可使极地冰川融化，海平面每10年将升高6厘米，因而将使一些海岸地区被淹没。全球变暖也可能影响到降雨和大气环流的变化，使气候反常，易造成旱涝灾害，这些都可能导致生态系统发生变化和破坏，全球气候变化将对人类生活产生一系列重大影响。

(二)臭氧层的耗损与破坏

在离地球表面10~50千米的大气平流层中集中了地球上90%的臭氧气体，在离地面25千米处臭氧浓度最大，形成了厚度约为3毫米的臭氧集中层，称为臭氧层。它能吸收太阳的紫外线，以保护地球上的生命免遭过量紫外线的伤害，并将能量贮存在上层大气，起到调节气候的作用。但臭氧层是一个很脆弱的大气层，如果进入一些破坏臭氧的气体，它们就会和臭氧发生化学作用，臭氧层就会遭到破坏。臭氧层被破坏，将使地面受到紫外线辐射的强度增加，给地球上的生命带来很大的危害。研究表明，紫外线辐射能破坏生物蛋白质和基因物质脱氧核糖核酸，造成细胞死亡;使人类皮肤癌发病率增高;伤害眼睛，导致白内障而使眼睛失明;抑制植物如大豆、瓜类、蔬菜等的生长，并穿透10米深的水层，杀死浮游生物和微生物，从而危及水中生物的食物链和自由氧的来源，影响生态平衡和水体的自净能力。

(三)生物多样性减少

《生物多样性公约》指出，生物多样性“是指所有来源的形形色色的生物体，这些来源包括陆地、海洋和其他水生生态系统及其所构成的生态综合体;它包括物种内部、物种之间和生态系统的多样性。”在漫长的生物进化过程中会产生一些新的物种，同时，随着生态环境条件的变化，也会使一些物种消失。所以说，生物多样性是在不断变化的。近百年来，由于人口的急剧增加和人类对资源的不合理开发，加之环境污染等原因，地球上的各种生物及其生态系统受到了极大的冲击，生物多样性也受到了很大的损害。有关学者估计，世界上每年至少有5万种生物物种灭绝，平均每天灭绝的物种达140个，估计到21世纪初，全世界野生生物的损失可达其总数的15%~30%。在中国，由于人口增长和经济发展的压力，对生物资源的不合理利用和破坏，生物多样性所遭受的损失也非常严重，大约已有200个物种已经灭绝;估计约有5000种植物在近年内已处于濒危状态，这些约占中国高等植物总数的20%;大约还有398种脊椎动物也处在濒危状态，约占中国脊椎动物总数的7.7%左右。因此，保护和拯救生物多样性以及这些生物赖以生存的生活条件，同样是摆在我们面前的重要任务。

(四)酸雨蔓延

酸雨是指大气降水中酸碱度(PH值)低于5.6的雨、雪或其他形式的降水。这是大气污染的一种表现。 酸雨对人类环境的影响是多方面的。酸雨降落到河流、湖泊中，会妨碍水中鱼、虾的成长，以致鱼虾减少或绝迹;酸雨还导致土壤酸化，破坏土壤的营养，使土壤贫瘠化，危害植物的生长，造成作物减产，危害森林的生长。此外，酸雨还腐蚀建筑材料，有关资料说明，近十几年来，酸雨地区的一些古迹特别是石刻、石雕或铜塑像的损坏超过以往百年以上，甚至千年以上。世界目前已有三大酸雨区。我国华南酸雨区是唯一尚未治理的。

(五)森林锐减

在今天的地球上，我们的绿色屏障——森林正以平均每年4000平方公里的速度消失。森林的减少使其涵养水源的功能受到破坏，造成了物种的减少和水土流失，对二氧化碳的吸收减少进而又加剧了温室效应。

(六)土地荒漠化

全球陆地面积占60%，其中沙漠和沙漠化面积29%。每年有600万公顷的土地变成沙漠。经济损失每年423亿美元。全球共有干旱、半干旱土地50亿公顷，其中33亿遭到荒漠化威胁。致使每年有600万公顷的农田、900万公顷的牧区失去生产力。人类文明的摇篮底格里斯河、幼发拉底河流域，已由沃土变成荒漠。中国的黄河流域，水土流失亦十分严重。

(七)大气污染

大气污染的主要因子为悬浮颗粒物、一氧化碳、臭氧、二氧化碳、氮氧化物、铅等。大气污染导致每年有30-70万人因烟尘污染提前死亡，2500万的儿童患慢性喉炎，400-700万的农村妇女儿童受害。

(八)水污染

水是我们日常最需要，也上接触最多的物质之一，然而就是水如今也成了危险品。

(九)海洋污染

人类活动使近海区的氮和磷增加50%-200%;过量营养物导致沿海藻类大量生长;波罗的海、北海、黑海、东中国海(东海)等出现赤潮。海洋污染导致赤潮频繁发生，破坏了红树林、珊瑚礁、海草，使近海鱼虾锐减，渔业损失惨重。

Protect environmental health and build a good home -- speech

The teachers! The classmates! Everybody is good! My topic today is "protecting the sanitation of the environment and building a beautiful homeland."

We live on earth, and the earths environment is protected by everyone. Head is LanYingYing day, is at the foot of green land, the majestic beauty of high mountain, the flow of water on the bottom, the tall green trees, the bright beautiful flowers, the earths favor of human is so beautiful environment, we can feel life here is very comfortable and happy, some people, however, not only protect the environment, also damage the environment, this is what a shameful act.

Currently, yichang is creating a national health city. There is no national health city in hubei province, but there are national health cities in the underdeveloped areas of the west. The city of yichang province, the world three gorges dam and ge zhou dam are located in yichang, the golden three gorges, the silver dam, the green yichang. The beauty of the mountain.

In the second half of last year, we started the "triple town" campaign and should start from me. Now the streets are littered with litter, spitting and scribbling. The dustmen tore up the rubbish ads, the people secretly taped up, and the people scrawled on the walls with paint, called the "psoriasis" of the street. These dirty and messy phenomena and to be governed.

The three orders of the state have led to the prevention and reduction of pollution and pollution, and the protection of air and environment. Now there are more and more cars, and the emissions are getting worse and worse. There are factories, sewage, pollution and water quality that directly harm crops and live life.

What is the benefit of this environmental destruction, and the destruction of the environment? Teachers, students, and to strengthen the awareness of environmental protection, improve their quality of civilization, actively join the "tri-cities lianchuang" activities, must start from me, starts from the minor matter, do a civilized, townsfolk hand in hand to build better homes!

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.

The earth is our common homeland, we will not be able to live without the earth, so we should protect our home, cant let those greedy people destroy the earth.

Due to the deforestation of people, from underground oil, coal, discharge of sewage, chemical plant, built the earth has been scarred, because the tree is his bones and muscles, underground oil is his blood, the coal is his insides, the earth must be very painful, very hate him sons and daughters, should treat him so, but people did a show of indifference, said: "the earth is not to provide us with resources, hearing this, I am very sympathetic to the earth, feel sad for the earth."

And better homes in my heart is like this: people living in wooden houses, the home use is very of environmental protection, the source of all is depend on the sun can, as long as the sun will have electricity, car is the solar energy, environmentally friendly, green city, the birds come here to live and work in peace and contentment, singing a happy song, people no longer deforestation, wont hurt the earth, all living a happy good life, also wont kill some innocent little animals, the earth saw it all, happy smile, his scar is finally good, again is a fresh world.

While people used to hurt the earth, but now most people realize his mistake, and the country will also from time to time to do a publicity, to remind people to protect the environment, to become a good citizen, if people correct mistakes, I think my homeland in my heart, can come true soon.

地球是我们共同的家园，没有了地球我们将无法生存，所以我们要保护我们的家园，不能让那些贪心的人破坏地球。

由于人们的乱砍乱伐、从地下抽油、挖煤、排放污水、建化工厂，地球已经伤痕累累，因为树木就是他的筋骨，地下油是他的血液，那煤就是他的五脏六腑呀，地球一定很痛，很恨他的儿女们，竟然这样对待他，可人们却一副无所谓的样子，说：“地球不就是给我们提供资源的吗，听了这话，我非常同情地球，为地球感到悲伤。”

而在我心中的美好家园是这样的：人们都住着木头房子，家里用的东西都是很环保的，一切都是靠太阳的源能，只要有太阳就会有电，车都是太阳能的，很环保，城市里绿树成荫，鸟儿们都来这安居乐业，唱着愉快的歌声，人们不再乱砍乱伐，不会再伤害地球，都过着幸福美好的生活，也不会再杀害一些无辜的小动物，当地球看到了这一切，高兴的笑了，他的伤痕终于好了，又是一个精神焕发的地球了。

虽然人们以前伤害了地球，但现在大部分人都认识到自己的错误了，而且全国也会时不时的做一做宣传，时刻提醒人们要保护环境，做一个好公民，如果人们都改正错误的话，我想我心中的美好家园，不久就能成真的了。

In my hometown, the air is polluted seriously. However, in recent years,

the pollution gets from bad to worse, because of the increasing number of

private cars. Especially during the rush hours, too many private vehicles move

slowly on narrow roads, emitting a large amount of waste gas. Moreover, the

poisonous gas sent by the nearby factories is also one of the main causes of

pollution. Therefore, it’s demanded that immediate and effective measures must

be taken to restrict private cars and public transportation must be developed to

the largest extent. Besides, we should use renewable and clean energy

recourses.

Almost every country in the world faced the population problem.China has the largest population, so the one-child policy was necessay. In America, there were 2 billion people 20 years ago, now there were 3 billion. Some day they will have the same amount people as we had in china, will they apply our population control policyAnyway we could be sure they will not critize our population policy at that time.
