环境和人类英文作文（经典20篇）

With the broadcast of smog,this long-standing environmental problems,become the hot discussion once again.According to some reports,the frequent appearances of smog obscure the clarity of the sky recently.Some people drove slowly on the road because they could not see clearly. They also suffered from many illnesses caused by smog.

Smog is the general expression of various higher-than-permitted suspended particulate matter (such as PM2.5) in the atmosphere,which express the state of air pollution .It contains fog and haze,both of them are disastrous weather. Fog consists of a large number of tiny water or ice crystals.It’s actually a harmless natural phenomena that makes visibility worse .Haze is air pollution in which is mixed up with dust, smoke and other dry particles. The components that make up haze may have negative effect on peoples health, especially for children and the old.

So it’s necessary to find out the reason why leads to smog and work out the resolution.If we trace the cause for smog weather ,the main points are natural causes that include windblown dust and manmade causes which include three aspects.Firstly,china s air quality standards are rather lax and evaluation factors are limited.Secondly,some enterprises just go for economic interests instead of observing relevant law and regulations.Obsolete equipment、industrial fuel burning and manufacturing operations are high likely to emit much wasted air.Thirdly,across our society ,relevant protection awareness has not built up.Just for the sake of convience to go out,people rely more and more on travelling and working by car while car is the main cause for smog.

To settle this problem,a series of meaures should be taken as follows.Primarily,we should establish a sound control system of smog. Not only can environmental protection departments strengthen air monitor,but government should enact more strict laws and regulations.Moreover,Reduce pollution sources is the fundamental solution to cut air pollutants. For example,we can reduce the amount of fuel vehicles or close down high polluting enterprises.Developing green and energy-saving energy can lower the emission of smog.Last but not least, People should do personal protection.They need to reduce the time for outdoor sports and pay attention to rest in smog days.Everyone all over the country should take measures to reduce the smog weather. We can use more public transport such as the bus and the underground so that the number of cars will be limited.Also,people should plant more trees. As far as I’m concerned ,if we work together to do such measures ,smog weather will vanish completely and we will get clear and blue sky.

人类，让我们保护环境!保护环境对人类来说是不可忽视的。

如今，工厂的大烟囱正冒着浓浓的黑烟;马路上，各种车子排放着尾气;小河里都是垃圾，肮脏极了……

昨天，我到菜场去，又看到了塑料袋。这是一种白色污染。去年的时候，通过整治，得到了一段时间的好转，电视也播放过了。然而，现在人们又忘记了它的危害，虽然它使用起来方便，却造成了环境的污染。风一吹，到处飞扬起来。埋在泥土下吗?可是又不会腐烂。焚烧起来吗?又污染了空气。只有大家同心携手共同拒绝白色垃圾，我们的家园才能更洁净，生活更美好!

生活中，随地吐痰，乱扔垃圾等不文明现象还是无处不在。从小做起，从我做起!共同爱护人类的家园——地球。

Topic:

Environmental problems are as big as not for individual country or individual people to address。

In other word， we have reached the stage that environmental problems be solved for international view。

To what extent do you agree or disagree?

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。

The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。

By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。

Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。

In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。

All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。

The impact is long term and international in scope。

Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。

Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

As far as I know,river pollution exist so many places in our country.A great deal of dead fish can be found floating on the surface of the river because of the serious pollution.Besides river pollution,there are also air pollution,soil pollution and so on.They have done great harm to human lives.Fortunately,more and more people have come to realize how serious the problem is.The government has begun to take measures to fight against pollution.But there is still a long way to go.We should take care of our earth and try our best to win the buttle against pollutin.

In modern society, we tend to become more and more aware of our living environment or physical environment, because we are not clean as before. So many people now choose their house as to its environment but not its location and expenses to afford it. As we all know, the environment pollution is more and more serious during these years, what we could do is to make great efforts in protecting environment gradually. As to government pollution, as to common people. We also try to protect it and make it remain clean. Although we have managed to protect the environment to a certain extent. It is still a very long way to go. Protect our enviorment The earth is our home,we must take care of it.We shoule make a less pollution as we know everybody in north America makes 1000 kilograms of the garbage everyday. Most of it is packaging Most of garbage turns into soil but not to plastic,plastic keepsfor many years it will pollute our environment so we shouldn’t waste thing we should make some things for recycling .

“There is only one earth”,I hope everyone will protect our environment well.

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?

所以此刻我们提倡过低碳的生活。

我的推荐是我们就应更经常骑自行车而不是开车骑一辆自行车，我们不仅仅能锻炼身体，也能保护我们的环境。

为什么不试试，我亲爱的朋友?

In recent years, tourism has been popular and played an important role in our nation’s economic growth. However, I am afraid that if tourism develops over, it will bring harm to the environment and give rise to many problems.

There are a few reasons accounting for my views and I would like to list three of them. One of the examples is that a large number of woods and other plants were replaced by all kinds of accommodation facilities or scenic spots. That definitely breaks the ecological balance of these areas and destroys the natural beauty of the scenic spots. Worse still, more pressure has been placed environment protection in that many tourists left their garbage in the scenic spots. In addition, over-developed tourism will occupy large numbers of farmland and lead to the shortage of the land.

In a word, tourism will be harmful to our environment if it is over development. Thus, I do not advocate that we development tourism without considering the environment. And we should keep the balance between tourism development and environment protection so that we can achieve the sustainable development between our nation’s economy and the environment.

People have been living on the Earth for thousands of years。Humanactivity influences the Earth。 Some people believe that theEarth isbeing harmed by human activity。 Others feel that humanactivitymakes the Earth a better place to live。 In my opinion， theearth isbeing damaged by human activity。 There are manystatementssupporting my opinion。

Human activity has damaged natural environment and almostexaustednatural resources。 Modern industry needs more and moreresources，including minerals， fuels and water。 So we confront ofthe seriousproblems such as the lack of fuels and water。Ecological balance isdamaged because factories occupy many placeswhere animals andplants live。 More and more buildings areconstructed and forestsbecome less and less。 If we cannotrecognize these problems andsolve them soon， we would finally losethe environment suitable forour living。 An other serious problem is the green-house effect。

Humanactivity decreases forests and increases the usage of fuels sothatthe gas of carbon dioxide is output more and more and there arenotenough plants to absorb it。 The green-house effect is moreobviousand more sensible these years。 Due to the effect， icebergsin thesouth polar and north polar melt and the sea level becomeshigherthan before。 I am worried about the cities nearby the sea andhopescientists find an effective method to eliminate thegreen-houseeffect。 Although we have advanced machines and our life seemsmorecomfortable than before， we have less chances to approachnaturesand less spaces to act。 The cities become bigger and if wewant tohave a picnic with our friends， we have to drive a longdistance tofind a natural place。 In fact， the spaces of humanactivity arebeing damaged by the skyscrapers and factories。 From the above statements， we can conclude that humanactivitybrings the Earth many damages。 Fortunately people haverecognizedthe point and I believe that the Earth will become abetter placeto live with our ceaseless efforts。

[英语作文：人类活动破坏了环境

环境是人类生存和发展的基础，大自然向我们提供了庞大的资源，而我们却不知感恩，对环境不停的污染，造成生态环境的破坏。人类不合理地开发、利用自然资源和兴建工程项目而引起的生态环境的退化及由此而衍生的有关环境效应，从而对人类的生存环境产生不利影响的现象。

随着工业时代的来临，人类科学技术水平的不断提高，人与自然的关系发生了逆转，人成了强者，而“温和的自然”却成了容易受伤的对象。高度提纯的化学制剂，如杀虫剂、油漆、洗涤剂等对自然环境构成了重大威胁；大规模的能源消耗改变了大气的构成，进而改变了地球气候；卫生条件的改善使人口急剧增加，人类活动大量破坏了地球的森林和湿地资源。于是，“温和的自然”变为“凶恶的自然”，人类施加给它的，它最终都要归还人类。被高度提纯的化学制剂污染了水和土壤的地区，畸形儿和绝症的出现比率大大高于正常；石油资源一旦枯竭，人类的生活质量和社会的正常运转必定遇到问题；气候异常必定带来水灾或干旱，饥荒也将伴随着种种天灾降临人间。“凶恶的自然”将再一次让人类成为弱者，人类和自然的关系又将回到起点。

因为人类不停的排放污水，排放废气，大量的浪费资源砍伐树木以致全球渔业资源减少90％；1/3的两栖动物、1/5的哺乳动物和1/4的针叶树种濒临灭绝；大自然调节气候、空气和水源的能力大幅下降；自然灾害对人类的冲击越来越多。

面对自然污染对人类的威害，全世界终于开始重视，联合国对此也召开了多次会议，讨论如何保护环境，各国也积极响应，推出了一系列的政策。

我们应该重视保护环境，环保也是我们每个人的事。

我们要学会废物利用，低碳环保，节约用水，尽自己的微薄之力，一起创造美好的家园。

同一颗星球，同一片天空，人类与大自然和谐相处，相信人类如果用爱去对待地球，地球也会回报我们。

让我们一起环保拯救满目疮痍的地球吧！

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。

保护环境

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，各国政府做了超多的工作。

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，应当透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我。

环境,是地球的表层,由空气、水和岩石(包括土壤)构成大气圈、水圈、岩石圈,在这三个圈的交汇处是生物生存的生物圈.这四个圈在太阳能的作用下,进行着物质循环和能量流动,使人类(生物)得以生存和发展.

据科学测定,人体血液中的60多种化学元素的含量比例,同地壳各种化学元素的含量比例十分相似.这表明人是环境的产物.人类与环境的关系,还表现在人体的物质和环境中的物质进行着交换的关系.比如,人体通过新陈代谢,吸入氧气,呼出二氧化碳；喝清洁的水,吃丰富的食物,来维持人体的发育、生长和遗传,这就使人体的物质和环境中的物质进行着交换.如果这种平衡关系破坏了,将会危害人体健康.

人类为了生存、发展,要向环境索取资源.早期,由于人口稀少,人类对环境没有什么明显影响和损害.在相当长的一段时间里,自然条件主宰着人类的命运.到了"刀耕火种"时代,人类为了养活自己并生存、发展下去,开始毁林开荒,这就在一定程度上破坏了环境.于是,出现了人为因素造成的环境问题.但因当时生产力水平低,对环境的影响还不大.

With the global warming getting worse, more people choose to live a low-carbon life for the purpose of reducing greenhouse gases.

We’d better save much water and paper and electricity. We should use less carbon and oil. It’s important to turn off the lights and computers when you leave the room. We should take our own bags in shopping instead of using plastic bags from the supermarket. We can buy few clothes which are unnecessary. We shouldn’t buy or use one-off cups or chopsticks or bowls. It’s good for us to walk or take bikes to school instead of taking cars. We can also plant more trees to change air around us.

Let’s take action and be a low-carbon people!

In recent years, tourism has developed rapidly in China. Many people believe that tourism produce positive effects on economic growth and we should try our best to promote tourism. But what these people fail to see is that tourism may bring about a disastrous impact on our environment. As for me, Im firmly convinced that too much tourists bring harm to the environment.

The bad impact of tourism on the environment has mainly expressed itself in various ways. One way is the proceof exploiting a new scenic spot. In order to attract tourists, a lot of artificial facilities have been built, which have certain unfavorable effects on the environment. This proceusually breaks the ecological balance of the area. In some mountainous places, trees are being cut down to build hotels for others to see and explore the beauty of the mountains. Then land slides and mud-rock flows come up. Another way the development of tourism has damaged the environment occurs when tourists go to scenic spots. Some tourists dont have the awareneto protect the environment, and ignorantly throw their garbage here and there. Some people even kill the local wildlife to eat, which badly damages the balance of the natural environment.

It is wrong to sacrifice the environment for the growth of tourism. We must keep in mind that too much tourists bring harm to the environment. We need to find a balance between satisfying the needs of tourists and reducing to a minimum the pollution they cause.

Will Tourism Bring Harm to the Environment? Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world. In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagernefor a glimpse of ages past . Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air. In sum , although tourism is playing an indispensable we`d better try to limit role in the society , I still believe that its speed according to the harm that brings to the environment.

The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.

Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.

What s more, every citizen should realize the seriousneof the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.

[旅游和环境的英文作文

The empty dam below my home was clean and tidy, and now the empty dam is full of rubbish, especially on rainy days, polluted water, and pedestrians passing by. The other people, because of the strength of the power, threw the garbage just hanging on the tree, ugly dead.

Im going to talk to the grown-ups. Theyre not talking to me. What are the kids doing? And drove me out. After I was driven out, I thought to myself, "this cant work. I can go to the neighborhood committee." So I went to the neighborhood committee. When I arrived at the neighborhood committee, I said to an aunt, "aunt, I want to reflect that someone in this building is littering." Aunt kind of say: "kid, the things we already know, one building will see you in a few days to clean the residents of the building to education, by the way you, you are quick to go home." I had to go home and wait for someone to clean. A few days later, we actually saw someone to clean, clean the people of the whole building up and down, left and right, fringes sweep of very clean, after finished, clean people will start all the residents of education building (including me), finished her education and clean people have left. After I passed this, I never saw him/them littering.

I suggest that we really want to protect the environment, because it is peoples responsibility to protect the environment. If people do get it right, we can have a good home.

关于人类与环境的英语作文 Human and the Environment

Last weekend, I wanted to swim in the river that I usually wen in the childhood. When I went there, I was shock. The river is no longer like before. It was full of rubbish. It seemed that the rubbish is from the villagers themselves. In order to put the rubbish nearer, they put all of them into the river. Not only the water is not clean any more, the river also smelt bad. I real touched. Why human and the environment couldn’t live harmonious? Long time ago, they could get along with each other. Why not now? People have to stop their behavior to harm the environment. Otherwise, it would cause destruction to both sides.

上周末，我想去我小时候经常去的那条河里游泳。当我去那里的时候，我很震惊。河水再也不像以前那样了。河里面到处都是垃圾。似乎这些垃圾都是村民丢的。为 了不走那么远丢垃圾，他们把垃圾都丢到河里了。水不仅仅不干净还会散发出臭味。我真的触动了。为什么人类和环境不能和谐地相处呢？很久以前，他们可以好好 相处。为什么现在不可以了呢？人们必须停止他们伤害环境的行为。否则，最后会是两败俱伤。

The earth is our only home to this day, and many people know that "there is only one earth, we should love it", but some people just talk about it and do nothing. They dont know that some very small actions can protect the environment -- by sorting out the garbage and using the battery to choose the rechargeable battery. Plant more trees in your spare time...

Now the earth is seriously ill, mainly caused by air pollution, water pollution and soil pollution.

Air pollution is mainly caused by the floating of material from factories, power stations and car exhausts into the atmosphere, making the air "dusty and footless". In cities with severe air pollution, people and animals are also affected and stunted. In addition, if the atmospheric carbon dioxide content is too high, it will produce a greenhouse effect, which will melt the ice in the south and south poles and reduce the ozone layer rapidly, which will eventually lead to global warming. It is not difficult to prevent this phenomenon. We can use the power of the transportation to replace the diesel fuel, thus reducing the exhaust emissions, the simplest way of course is to plant more trees.

Water source pollution is mainly caused by waste water and climatic factors. With the increase of population and the extension of human life, mankind will face unprecedented water scarcity. Some people say that the worlds water supply will be in short supply after 2030. To this, we must pay attention to saving and protecting water resources.

Soil pollution is my concern, because soil has a huge connection to air and water. Without soil to grow plants, there is no source of air, and soil is an important survival basis for plants and animals. Without soil, we humans could die. So we must protect the soil. There are many ways to protect the soil, such as in daily life, dont bury things like disposable batteries and foam plastics into the soil. We need to start small, and everyone is helping to protect the soil.

The earth is the cradle of life and the common home of mankind. We should love the earth and protect the earth.

how to save environment? i think we should do the followings: first, it’s best to ride a bike to school, don’t take a bus or a taxi. second, i will remember to turn off the lights when i leave the classroom. third, in my free time, i will collect the empty bottles and waste paper for recycling. the fourth idea is turning off the shower when i ‘m not using it. fifth, it is imporment to save water and money. also, i won’t spend too much money on expensive things. last, we had better not cut down the trees, we have to take care of the trees . i’ll try my best to save the energy, i hope i can do something for our country.

the environmental protection is the most major problem which in the modern life the humanity faces. must solve this problem must start from foundation. first, must massively propagandize, enhances peoples consciousness with understanding, strengthens the environmental protection consciousness. next, must carry on waste recovery use, reduces to forest-trees felling. also must strengthen to white pollution processing, little uses the plastic product. finally, must make improvement to clean aspect. causes the citys appearance to be neater. for earths tomorrow, we must start from the now diligently, will want the well local constable to protect the environment. to this us proposes as follows suggests: implementation trash classification packed in bags. like this not only can reduce the environmental sanitation workers work load, but also can even better basically arrive makes use of waste, to reduce the pollution, saves the resources.
