全球变暖现象英语作文(汇总20篇)

在这一则报导中，我学到很多事，但我第一个想到的是，造成地球变暖的原因是二氧化碳增加。

In this paper, I have learned a lot of things, but I think the first one is the cause of global warming, the increase of carbon dioxide.

为什么二氧化碳会增加呢?我想到的原因是人们常常开车、养食家畜、工厂大量排放黑烟……等。不过这些是大家可以一起解决，说不定可以改善地球继续暖化，例如：目的地很近的话可以骑自行车;目的地很远的话，可以搭乘公共交通运输工具;家畜的排泄物经过处理再排入河内;工厂可以建一座废弃处理厂……等。

Why carbon dioxide will increase? I think the reason is often drive, raising livestock, food factory emissions of smoke...... Etc.. But these are all can solve them together, it can improve the Earth continues to warm, for example: the destination is close enough to ride a bike; destination long enough, can take the public transport; waste livestock treated and then discharged into the Hanoi factory; to build a waste treatment plant...... Etc..

请大家不要小看二氧化碳的威力，等到海平面上升、都市浸水和农地淹没，到最后就会面临粮食不足的危机了。请大家跟我一起喊：“停止伤害地球的行为吧!我们居住的地球只有一个。”

Please do not underestimate the power of carbon dioxide, when the sea level rise, urban water and farmland submerged, eventually facing food shortage. Please call with me: "stop the harm to the earths behavior! Only one earth on which we live. "

Hang up red lanterns, happy song sings, with the crackling sound of firecrackers, the Spring Festival party. Below, lets go to a small case of the waste of the Spring Festival. Let SGO!

The Spring Festival: a waste of reciprocity

The Spring Festival is a traditional festival in our country. It is a happy day for family reunion. Most people visit relatives and give gifts to each other. Trinidad send goose, courtesy light weight friendship." It has already been regarded as a custom for many people to send gifts for the Spring Festival. Among the people I am investigating, most people actually spend a lot of money to buy gifts. In fact, we dont have to spend lots of money to buy so many gifts, in fact, as long as the greetings, relatives and friends also met the joys of.

The waste phenomenon of the Spring Festival two: travel out

In the new year, many people like to take their family together to travel, and the cost is quite high, with the convenience of a few million yuan. Some of them go abroad, some go to pray, go to...... The highway is the "car mountain car sea", in common words, one word - blocking! Take the Buddha, the Buddha is straight up the number of 2016. So, I ask you: is it necessary? After the Spring Festival, the best thing is to accompany their parents and children to go shopping street and accompany them. It is not necessary to go to such a distant place.

The waste of the Spring Festival three: set off firecrackers

Crackling crackling......" When it comes to the Spring Festival, firecrackers can be said to be an essential activity for people. But its a waste, too. The smell of smoke produced after the firecrackers will affect peoples health, and the explosion of firecrackers will frighten children and the elderly. The ear injury is beyond doubt -- tinnitus, hearing loss and so on. It will also pollute the environment and cause fires. Also, some people spend lots of money to buy many firecrackers, most will listen to the sound, see the beauty of it, is not how happy, we can choose the new year a more interesting way, do not have to put the choice of firecrackers to celebrate the new year, if it is to set off firecrackers, must go to the specified place a small amount of fireworks.

The waste of the Spring Festival is four:...

A Witness of a Theft Incident Yesterday, I witnessed a theft incident on my way home. The thief was so rampant that it left me a very deep impression. It was in the rush hour, when many people were buying tickets at the subway station. A woman took her purse out and paid for the ticket. Then she put her purse back into her bag and turned to leave, when a mid-aged man brushed past her muttering Excuse me. She didnt feel unusual and went into the station. Indeed, her purse had been stolen by that man. To our surprise, the thief seems not to be nervous at all and even began to look others up and down. Maybe he was searching for the next target. At that time some persons, including me, witnessed the process. But unfortunately, no one dared to warn that woman. This incident makes me ashamed and leaves me a deep thought. The pickpocket has posed a great threat to residents and visitors property safety. Undoubtedly, it is an urgent thing to take action to prevent pickpocket. However, it cannot depend on the police only. Instead, it needs our common efforts. We can not shut our eyes and mouths to the pickpocket any more. It should be kept in our minds that our forces are far beyond those thieves.

我读完《全球气候》时，我才发现环境的严重污染。

I read the "climate", I found that the serious pollution of the environment.

里面说，现在由于二氧化碳的严重增多，导致全球变暖，从而影响海平面上升0。5厘米。听起来不算多，可是地球上还有更大的淡水区，那就是南极和格陵兰岛，如果南极的冰全部融化，海平面会上升60米，再加上格陵兰岛的冰，海平面还会上升6米。现在的美国海边，经常有台风出现，导致巨大的经济损失，气候变暖使高山动物开始迁移，许多动物因为不适应环境而灭绝。

It said, now due to carbon dioxide more serious, leading to global warming, sea level rise and influence 0. 5 cm. This may not sound very much, but the earth has more fresh water area, it is the Antarctic and Greenland, if all the melting of Antarctic ice, the sea level will rise 60 meters, plus the Greenland ice, sea level will rise 6 meters. Now America beach, often have typhoon occurs, resulting in huge economic losses, due to climate warming in Alpine animal migration began, many animal extinction because they do not adapt to the environment.

所以我们要积极响应“保护环境，人人有责”的号召。

So we should actively respond to "Protect environment is everyones responsibility," the call.

Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.

很多人都认为是人类活动导致了全球气温上升。他们说全球变暖会对我们的环境造成可怕的后果，如干旱和洪水。

What should governments do to help prevent global warming? Give reasons for your suggestions.

政府该做什么来防止全球变暖呢?给出你建议的原因。

The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.

地球的温度正在迅速改变。导致很多气候变迁，如热浪、干旱和洪水。科学家认为这是人类活动污染了地球的大气层的结果。如果政府不采取行动来防止全球变暖的话，这可能会成为灾难。他们可以在三个方面上有所行动;支持研究，制订法律和保持公众知情。

Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.

首先，政府可以支持研究。例如，他们应该鼓励公司致力于汽车研发来减少污染。他们也应该支持来自风和水的电力替代能源，而不是来自石油和煤的电源。同时，他们应该主持会议来讨论温室气体排放的影响和可能解决问题的方案。

Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.

其次，他们应该制定法律限制公司发出的温室气体。私人公司应该因为遵循这些法律而得到奖励。他们也应该因为创造出污染而受到惩罚。

Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.

最后，每个人都是受到全球变暖的影响。因此，政府和个人在解决问题的过程中是很重要的。例如，他们应该鼓励家庭尽可能多的节省能源，尽可能多的使用更高效的灯泡或少用热水。他们也应该鼓励公众回收，因为这对每个人来说都是必须的。另一种节约能源的方法是公共交通系统。政府应该把钱花在公共交通使公众尽可能容易的节约能源。

In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.

总之，很明确的，各国政府可以做很多事情来防止全球变暖。他们应包括公司，支持科学家和鼓励个人保护地球。

On Uncivilized Behaviors

We cannot fail to notice that countless uncivilized behaviors exist in ourdaily lives, such as spitting, talking loudly, littering, saying nasty words inpublic places and so forth. All these are bad manners that we should not losesight of. As an ancient land enjoying a splendid civilization spanning over5,000 years, China is witnessing a surge in improper acts that every Chinesecitizen should feel ashamed of. Uncivilized behaviors by a host of Chinese bothat home and abroad have seriously affected Chinas image, according to aneditorial posted on People Dailys official website.

As Chinese, we should not get offended when others point out our weaknessesbut should focus more attention on improving ourselves. We should strive toidentify the causes of those improper behaviors and find ways to eliminatethem. There are a host of causes, I would argue, behind this trend. To nameonly one: the lack of moral education. The government should wage a massivemoral campaign to fight against this trend and we ourselves should endeavor tobehave decently in our daily lives. As college students of the new age, weshould take the leading role.

When global warming, the world have changed dramatically.

The Antarctic ice and snow melt, human feeling will be under water, it is human to take the consequences. Arctic overlord, the polar bear also gradually extinction due to global warming. Has been the mother to a pair of scissors to bear, baby bear curiously ask: "mother, with scissors stem what ah?" Mom replied in a tone of command: "quick shearing, longer so thick hair will be hot dead!" Naive to bear looked at his mom, "we live in the ice and snow, how can heat? This is our coat, without it will be cold, cant cut!" Mother bear tone with a sad and sigh: "global warming, in does not adapt, now Im afraid go!"

Global warming, the polar bear cant find food, even little bear, it is be compelled helpless! Humans shall make profound reflection to your behavior, but, when global warming, human couldnt realize his mistake! Only know no longer suffer from the cold in winter, the temperature rose, the cold has gone, only the immediate interests, didnt know that will be far away from the white snow, originally should be open the flowers in the winter.

When global warming, I hope this to human consciousness already consequences. Early up, to stop all this happen!

当全球气候变暖时，世界发生了巨变。

南极，冰雪融化，人类感觉将要处于冰水之中，这是人类自食其果。北极的霸主北极熊，也因全球变暖而逐渐走向灭绝。一直熊妈妈向小熊递来一把剪刀，熊宝宝好奇地问：“妈妈，用剪刀干什么呀?”妈妈以命令的语气回答：“快剪毛，再长这么厚的毛会被热死的!”小熊天真的望着妈妈：“我们住在冰天雪地里，怎么会热呢?这是我们的外衣，没有它会受冻的，不能剪!”熊妈妈的语气中带点悲伤和叹息：“现在全球变暖，在不适应，恐怕就走向灭亡了!”

全球变暖，北极熊无法找到食物，甚至食用小熊，这是被逼无奈呀!人类应当对自己的行为进行深刻的反省，可是，当全球变暖时，人类还无法意识到自己的错误!只知道冬天不再受寒风的折磨，温度上升了，寒冷已离去，只顾着眼前利益，可不知道以后将远离那洁白的雪，原本应在寒冬中开放的花。

当全球变暖时，希望人类早已意识这以后果。趁早弥补，阻止这一切的发生!

industrial pollution is the industrial production process of the formation of gas, waste water and solid emissions on the environment pollution. industrial pollution is mainly concentrated in a few industries. paper, chemical, steel, electricity, food, mining, textile and other seven sectors accounted for the total wastewater discharge 4 / 5. paper and food industry accounts for cod emissions of cod emissions 2 / 3, non-ferrous metallurgical industry, heavy metal emissions of heavy metals emissions account for nearly 1 / 2. industrial pollution is the industrial enterprises in the production process, including human biological survival and reproduction of the natural environment against. pollution is mainly from the production of the "three wastes" (waste water, waste gas, waste) and all kinds of noise caused can be divided into water pollution, air pollution, waste pollution, noise pollution.

industrial pollution hazard. first, a large number of industrial production in the discharge of untreated water, gas, slag and other hazardous waste, it will seriously damage the ecological balance of agriculture and natural resources on the development of agricultural production caused great harm; second, industrial "three wastes" of the industry production itself is also very serious hazards, toxic pollutants can corrode pipes, damaged equipment, affecting plant life, etc.; third, environmental pollution, rampant pollution, directly endangering the health of the masses; also some contamination is not easy to find, after the damage that has very serious

On the eve of the new year, everyone is enjoying the delicious new years Eve dinner, setting off firecrackers and giving gifts, but they once thought of wasting, so there was a waste in the new year.

This is the result I had to ask my mother once. At the time of the new year, we all eat up the stomach, but there are many more meals to go to sleep. When you get up in the kitchen in the morning, you cant see their shadows again. I ran to ask mother, mother said: “ those ah, all I fell off, you have to eat me to cook. ” Im puzzled that mom is usually very frugal, so how to waste it this time! So, I found the phenomenon of waste in the New Year!

Students, know Li Shenyou a poem “ who knows the dish, the grain is hard ”? These waste of food enough to eat for many days, this is by how many sweat, I believe that many families have been such a phenomenon!

And the fireworks, and dont see it as beautiful when it is launched. In fact, it contains a lot of harmful substances to the human body, and it will also cause pollution to the environment. Some people also buy fireworks and do not put it, is it a very waste of money? The right amount of fireworks is good, not too much!

There is a gift, we will send in at present, if every day stopping, not every day to send a gift? Its a lot of money and a lot of wrapping paper.

There is a lot of waste, I dont say it, we dont waste, a happy year!

I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.

First of all, global warming is one example, soak in the hot weather in summer air conditioning becomes a new "hobby", but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.

Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust serious affect our nong cough, throat inflammation... . According to concerning sectional statistic Chinese per capita emissions of carbon dioxide emissions 2.51 tons each year. The changes in the harsh environment around us.

More important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs "of the south-north water diversion project".

In order to save the planet, people all over the world should be: dont open air conditioning, use recycled environmental protection bags, dont use plastic bags, take the bus, dont throw waste batteries... Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!

我在电视上、网络上经常看到现在的地球已经被人类破坏的千疮百孔，如果我们在不同心协力的保护它，地球将在不久的将来彻底的毁灭。随着人类科技的发展越来越快，科学随之产生的负面影响逐渐体现出来，下面我就给大家举几个例子来说明为什么专家会预言地球将在多年后不复存在。

首先全球变暖就是一个例子，天气炎热在酷暑里泡空调成为一项新的“业余爱好”，但人们可曾想过空调会带来什么负面影响呢?空调排出的气体中含有大量的甲烷，输送到外面甲烷也是导致全球变暖的气体，同时空调还会浪费掉大量的电力资源，所以要尽量避免使用空调或适当使用即可。

另一个原因就是：二氧化碳，汽车尾气与工厂废气中含有大量二氧化碳，而二氧化碳最可能导致全球变暖。现在汽车逐渐增多，太多的尾气严重影响着我们咳嗽、喉哝发炎……。据有关部门统计中国每年的二氧化碳排放量人均排放量达到2.51吨每年!我们周围的环境在恶劣的变化。

更重要的原因就是：森林减少，农田减少，水资源破坏，水污染严重，新鲜的淡水供应成了问题，许多地方吃水已经成了一大问题。现在国家也在大规模的搞费力，费神，又费财的“南水北调的工程”。

为了拯救地球，全世界的人们都应该做到：不开空调，使用回收环保纸袋，不用塑料袋，乘坐公交车，废旧电池不要乱扔……等生活中的点点滴滴。其实环保并不难，只要大家支持环保就是你给地球最好的礼物，行动起来吧，这就是一股强大的力量!

it was the industrial revolution that gave birth to environmental pollution as we know it today. the emergence of great factories and consumption of immense quantities of coal and other fossil fuels gave rise to unprecedented air pollution and the large volume of industrial chemical discharges added to the growing load of untreated human waste. chicago and cincinnati were the first two american cities to enact laws ensuring cleaner air in 1881. other cities followed around the country until early in the 20th century, when the short lived office of air pollution was created under the department of the interior. extreme smog events were experienced by the cities of los angeles and donora, pennsylvania in the late 1940s, serving as another public reminder.环境污染现象英语作文二

industrial pollution is clearly one of the biggest contributors to our polluted landscapes, at least here in the west. there are plenty of causes of land pollution, from urban and industrial ones, to rural and agricultural sources.

but which kinds of land pollution are the most important? and what can we realistically do to help prevent more pollution?

this part of the site gives an overview of some of the most important causes of land pollution, including industrial pollution.

there are also some recommendations for helping avoid domestic land pollution incidents.

Some people may believe that going to classes should be optional, but I disagree. I dont understand how university students can expect to learn anything if they dont attend classes. Personal experience can help people learn about themselves and the world outside the classroom, but when it comes to learning about academic subjects, students need to be in class.

有些人可能认为，上课应该是选择性的，但我不同意。我不明白如果大学生不去上课，他们如何能够学到东西。个人的经验可以帮助人们了解自己和课堂以外的世界，但就学习学术课程来说，学生是需要去上课的。

In class they receive the benefit of the teachers knowledge. The best teachers do more than just go over the material in the class textbook. They draw their students into discussion of the material. They present opposing points of view. They schedule guest speakers to come, give the students additional information, or show documentary films on the subject.

在课堂上他们接受教师传授的知识的好处。好的老师不仅仅是照搬教科书上的材料。他们把他们的学生带入材料的探讨中。他们提出了相反的观点。他们安排嘉宾的到来，给学生带来更多的信息，或展示那个主题的纪录片。

Also, attending classes on any subject teaches more than just facts. It teaches students how to learn, how to absorb information and then apply what theyve learned to other situations. Their teacher is the best one to help them with these skills. They cant learn them just by reading the textbook.

同时，任何学科的课程所教的不仅仅只是事实。会教学生如何去学习，如何吸收信息，然后在其他情况下运用他们所学到的知识。老师是最好的人选来帮助他们掌握这些技能。那是他们不能仅仅通过阅读课本而学习到的。

Going to class also teaches students how to work with the other members of the class. Many times students will be given group assignments. This is different from what they did in secondary school. Here theyre with people from different backgrounds and experiences. In this situation, they learn how to handle working with people different from themselves to achieve a common goal.

去上课也教导学生如何与班上的其他人共处。很多时候学生要做小组作业。这与他们在中学中是不同的。在这里，他们有着不同的背景和经历。在这种情况下，他们学会了如何处理与自己不一样却有着共同的目标的人。

Going to class also teaches students responsibility and discipline. Having to be at a particular place at a particular time prepares themselves for getting a job. Being at a place on time with an assignment completed prepares them for a career.

去上课也教学生责任和纪律。必须在特定的时间、地点自己做好找工作的准备。在规定的地方按时完成任务是为找工作而做准备。

In short, by going to class, students learn more than just information from the teacher. They also learn how to learn, how to work with others, and how to work responsibly. These are not optional skills in life, so attending classes should not be optional in college.

总之，去上课的学生不仅仅是从教师身上学到知识。他们也学到如何学习，如何与他人合作，如何负责任地工作。这些都是生活必备的技能，所以不应该在大学上课是可选的。

With the bursts of firecrackers. The celebration of the Spring Festival comes at last.

However, at the same time, people play a lot of waste. According to the survey, the waste of the Spring Festival is 10 times as much as usual (non holiday). These figures are really to be counted, and you can imagine how amazing it is. So, at the same time, we do not forget to save.

The waste of food is especially serious during the Spring Festival. The new year, we have to prepare enough things in the supermarket to buy special purchases for the Spring Festival, convenient to move home; there are people who work units, friends. The source of special purchases for the Spring Festival not put, the home refrigerator, but on the outside. But just a few days later, the weather is getting warmer. The thing broke out immediately, couldnt eat it, and had to throw it away. There are also years of night meal, in order to be rich, all families have bought a lot of things, but they can eat very little, and finally there is a lot of surplus. “ more than &rdquo in years; a good omen, but the remaining things, but in the case of no one, were poured into the ditch or the roadside. New years festival is the peak of consumption. At this time for the Spring Festival shopping, eat and drink, do special purchases for the Spring Festival can. However, do not forget to save in the consumption, to eliminate waste.

In addition to the waste of food, the waste of the new year is very serious. In our lives, there is often a waste of electricity. As far as our family is concerned, thirty nights in the big year, the lanterns are hung up on my house, all night, and how much electricity is consumed. Also, in order to have a good sign, on the thirty night houses are the lights lit, night lights, electricity consumption as can be imagined how much.

There is a lot of waste in the Spring Festival. For example, gifts are given during the Spring Festival, which also presents the waste of gift packaging. Some units send gifts to employees in the new year, and everything is covered with beautiful packaging. It is too big to take home, but when the packing is removed, the original thing is much smaller. These packages are about half of the space, and most of them are new, so its a bit wasteful. Many shopping malls, supermarkets can see, many for the gift of people in the selection of those exquisite gift boxes. There is only two bottles of wine in a box that looks like the size of a normal TV screen. A lot of gifts are packed in layer after layer, so people dont know what it is inside. Its even doubted that the box is worth more than the inside. During the Spring Festival, the packing box is the most important time. It did cause a lot of waste of paper and plastic.

“ save the resources, start from me. ” to eliminate waste, the key is to start from yourself, start from small things, start from now!

Earth’s temperature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet.

地球的温度开始太阳。大约百分之30的太阳光被反射回太空的光明面与云冰。在余下的百分之70，多数是由陆地和海洋吸收，其余的被大气层吸收。吸收太阳能加热我们的星球。

As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane.

当岩石，空气，和温暖的海洋，他们辐射热能源(热辐射)。从表面上看，这种能量进入大气层，大部分是由水蒸气和长寿命的温室气体如二氧化碳和甲烷的吸收。

When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight.

当他们吸收辐射能量从地球表面，微观水或温室气体分子变成小加热器-就像在壁炉的砖，他们散发热量，即使在火熄灭。他们在所有方向辐射。能量辐射回地球加热低层大气和表面，增强他们从阳光直射加热。

This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.

这种吸收和辐射热的气氛自然温室效应有利于地球上的生命。如果没有温室效应，地球表面的平均温度将是一个非常寒冷的18°C(0°F)而不是舒适的15°C(59°F)，它是今天。

About two weeks from now, college students will begin to enjoy their long summer holidays. Many are looking for odd jobs, of which tutoring is almost the most popular one.

These students say, by doing pan-time jobs, they can not only make some money for next terms tuition, but also enrich their holidays. They prefer to be tutors because this has more to do with what they have learned in class.

As a student, I myself have also been a tutor. But I didnt wait in line until I was chosen. I put up an advertisement with my school scripts attached. So, my suggestion to my fellow students is: be a tutor only when you are good at your courses.

Recently, global warming has become a hot topic among people. It results

from serious air pollution. As the environmental pollution is more and more

strict, the temperature of all the world has dramatic increased. Gradually, some

disaster such as drought, floodandGlaciers Melting follow. How terrible it is!

Therefore, we need to protect our earth and fight against the disaster

together.We should start from the trivial side. Making contribution to

protecting our home.
