有些人不珍惜地球赐予我们的一切，例如人们乱砍乱伐，大量使用一次性筷子和乱扔塑料袋，制造白色垃圾等已经给大自然带来了许多环境问题，严重影响了我们的生活。还有大气污染，酸雨和臭氧层等带来的危害都是大自然给人类带来的灾害，人们乱砍乱伐，乱扔塑料袋和使用一次性筷子等，这些就是人们不尊重大自然而造成的，没有自然，便没有人类。这是世界一大朴素的真理，人们只会一味的抢夺自然，征服自然，只会破坏生态系统，咎由自取，使人类濒于困境。切记，保护环境就等于保护我们自己生存的环境。

poisonous gas is given off by factories。 Trees on the hills have been cut down

and waste water is being poured continuously into rivers。Furthermore， wherever

we go today， we can find rubbish carelessly disposed。 Pollution is， in fact，

threatening our existence。

and for our later generations。 Fortunately， more and more people have realized

these problems。 Measures have been taken to cope with these problems by the

government。 Laws have been passed to stop pollution。 I hope the problem will be

solved in the near future and our home will bee better and better。

I have had a dream, in the dream I dreamed that the qingshui river became very terrible.

I went to qingshui river with my father and mother. I was just walking towards the river when I heard a loud crying. I followed the sound of the past, it was a piece of grass. I squatted down and asked, "grass, why are you crying here?" The grass said, "this is a vast prairie, but people are going to build a big house here. My sisters have been pulled out, and I am the only one who has not been pulled out." "Said the grass, and began to cry again.

I stood up, turned and heard: "help me." I walked past, originally is qingshui river to cry. "Why are you crying?" I asked curiously. "Please help me," he said. I saw an aunt throw a pack of garbage into the water. Plastic bags fly apart in the air, wrapped in peel, the leftover soup is scattered into the river. I went over and said, "aunt, its wrong of you to do so." The aunt said angrily: "you care for me? Little thing. You see, everybody is not like this?" I looked across the river and some of the people on the bank had coal dust, some threw waste paper. Some factories are discharging black and black waste water, along the river, into the distance. Then I saw a yellow and yellow thing floating on the river.

God, thats terrible!

Wake up and think of the old water river. In the summer some people play in the river, and some fish swim freely in the water. On the bank of the river, the willows fly, and the bees sing.

[家乡环境变化英语作文

Nowadays， more and more people like to travel in their holidays. The other day I read a report about the ways people spend their holidays. It is reported that in recent yiars several new holiday habits have been developed. Among them， the most interesting one is the growth of the so-called holiday camps.

From the report we can see that in 20XX，40 percent of people stayed at home for holidays. But now the proportion has reduced to 9 percent. More people go out for fun. The proportion of camping and traveling abroad was increasing steadily， from 10 percent in 20XX to 38 percent in 20XX， and 12 percent in 20XX to 26 percent in 20XX respectively. People enjoy the fresh air， clean Water and green hills when they go camping in the suburbs. In 20XX，38 percent people enjoyed going to the seaside while in 20XX only 27 percent prefer to go there. What great changes!

Why did those changes appear? I think there are several reasons. First， it s because people can afford traveling. Second， people prefer to pursue a high-quality and colorful life. Third， their attitudes to relaxation have changed. Less people want to save much money by leading a simple life. In short， peoples living standard today has been rising greatly.

d happy holiday.

Because of the fiction movie 2012 which describes a horrible scene that the whole world was destroyed by earthquake, volcano and tsunami, the view of doomsday is making a great clamor. Mayans predicted December 21, 2012 is the end of the world and the sun of 22th will never rise again.

Though it is now seems that this prediction is just a nonsense without any scientific support, it did provoke peoples thinking about environment. In awake of the prediction, we cant help asking why this horrible prediction happen? I think one answer may be related to the environmental degradation. As we all can see and feel, the worlds environment is going downhill with severely polluted rivers and airs. More often we cant see clearly the sun because of heavy air suspended matter caused by pollution. If continues going this way, I think the doomed day will come true if not now, then one day.

In consequences, for the sake of our own life, we should take efforts to protect the environment and save this planet. is the alarm bell to human beings that we should protect our planet, culture and civilization. Otherwise, the doomsday will come soon.

1972年6月5日-16日，“联合国人类环境会议”在瑞典的斯德哥尔摩召开，这是人类历史上第一次在全世界范围内召开的保护人类环境的会议，具有里程碑式的意义，是人类环境保护行动史上划时代的事件。会上，各国与会代表建议联合国大会将“联合国人类环境会议”开幕日——“6月5日”定为“世界环境日”。同年10月，第27届联合国大会接受并通过了这项建议。

On June 5, 1972 -16, the United Nations Conference on the human environment "in Sweden was held in Stockholm, this is the first time in human history was held in the world within the scope of the conference on the protection of the human environment, has the meaning of landmark, is the history of mankind environmental protection action on the epoch-making event. At the meeting, delegates suggested that the United Nations General Assembly will be "the United Nations Conference on the human environment" opening day "June 5th" as the "world environment day". In October of the same year, the twenty-seventh session of the UN General Assembly accepted and adopted the proposal.

“世界环境日”的意义在于提醒全世界的人们注意全球环境状况的变化，以及人类活动对环境已经造成的危害，要求联合国系统和世界各国政府在每年的这一天开展各种宣传、纪念活动，以强调保护和改善人类环境的重要性和迫切性。联合国环境规划署也将在每年的世界环境日选择一个成员国举行“世界环境日”纪念活动，发表《环境现状的年度报告书》，确定该年世界环境日的主题。在“世界环境日”的那天，各国政府和全世界的人们都要举行各种形式的纪念活动，宣传环境保护的重要性。呼吁全体地球公民为维护、改善人类环境而不懈地努力。

"World Environment Day" is to remind people to the attention of the whole world changes the state of the global environment and human activities on the environment, the harm has been caused, the United Nations system and governments around the world every year on this day to carry out a variety of promotional and commemorative activities, in order to emphasize the importance of protecting and improving the human environment and the urgent. The United Nations Environment Programme will also choose a member of the "World Environment Day" celebration in the annual World Environment Day, issued a "state of the environment in the annual report of the year", the theme of world environment day. That day in the "World Environment Day", governments and people all over the world have held various forms of commemoration, publicize the importance of environmental protection. Calls upon all citizens of the earth for the maintenance and improvement of the human environment and make unremitting efforts to.

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.

仍有许多问题近年来环境保护。最严重的问题之一是严重污染的空气、水和土壤。空气污染给人们的健康带来极大的危害。被污染的水会引起疾病和死亡。更重要的是,植被已大大减少,现代城市的快速增长。

为了保护环境,许多国家的政府已经做了很多。介绍了立法措施控制空气污染,以保护森林和海洋资源,制止任何环境污染。因此,政府在环境保护中扮演最重要的角色。

在我看来,为了保护环境,政府必须采取更具体的措施。首先,它应该让人们充分认识到通过教育环境保护的重要性。第二,更应努力把人口计划生育政策付诸实施,因为更多的人意味着更多的人意味着更多的污染。最后,那些故意破坏环境者的人应该受到严惩。我们应该让他们知道破坏环境就是毁灭人类自己。

The communication of the intention can have been done with the person in the country though the word did not run well. However, I thought that the handicap of the word was large. I thought it was good if the word could be understood more many times. Therefore, I think that I should study the language study more.

Yes, the government has been doing a great job. And what about us? What should we ourselves do? Some of us may think that is quite difficult. But it can be as simple as: do not litter; and strictly observe the rules and regulations of the tourist areas. Use as few plastic bags and boxes as possible. When traveling, and whenever possible, use public transportation instead of always driving your own car.

It is not that far to reach, right? It is just as simple as the famous slogan for travelers in TianHuangping says, “Please take away nothing but your smile, and leave behind your but your footprint.” I believe that more and more people now are becoming aware of the importance of environment protection. Just imagine if you sit in the Large Bamboos Sea and taste the white tea of Anji, that is so wonderful and comfortable. So now let us turn our passion into action. Give ourselves a brighter future to head to. Leave our next generation a brighter, greener, and better world to stay in. If not us, who? If not now, when?
