We should have cherished nature and preserved it. Conversely, however, we have been continually spoiling it, even to a shockin

2、g degree. Now lets see what we have dong. Thousands of trees have been cut down per year, which has caused soil erosion. Hundreds of thousands of tons of CFCS have been left in the higher sky in the last decade which has led to the ozone layer leak above the South Pole that covers an area of that of

3、 the United States. Million tons of fuel containing nitrogen and sulphur have been consumed per year, which has eventually resulted in acid rain throughout the world. Similarly, ecology has been affected as well. And considerable number of species have been extinct as the years go by many creatures

4、which were common in the past are becoming less and less, even rare. The Tibet antelope, for instance, is a good example. Since the antelopes of Tibet have a part of fur on their body which can be made into a precious cape, driven by some lawless dealers many villagers killed antelopes excessively a

5、nd shocking for the large suns of fortune. Because of this, the number of the antelopes of Tibet has sharply fallen from over one million to less than one hundred thousand. And whats more, the number has now decreased by 20 thousand per year. Qing Zang Platean, which was their homeland, is their tom

6、bs now. This is how nature has suffered what we have done to it. However, nature and suffer any more. She lost her temper and could no longer possibly put up with humans. She gave humans harsh punishment, which she thought they deserved. The acid rain has caused the less of more than 100 billion dol

7、lars throughout the world per year. And because of desertisation, soil is becoming more and more barren. The soil of many planes is now until for growing plants. The air is less fresh, and a lot of people even get many stranger diseases. Those are all the punishment of nature to humans pollution. On

8、 the other hand, human being suffer a lot as well. So it leads to a serious of questions- Why cant we live harmoniously with nature? Why cant we set a balance between human and nature? Why cant we pay more attention to nature and try to reserve it? Therefore, before we take immediate measures to do

9、something, we should be aware of the fact that Conquering the nature will never be our goal, instead, we should take the nature as our intimate friend. Preserving nature is not only preserving our home, but the civilization of human community as well. 以自然为题的英语演讲稿2 We often say that the earth is our

10、homeland and human society comes from nature. Therefore, I think our society is a part of nature. People should live harmoniously with nature. All the materials we need to live with come from nature, but we should also repay the nature, rather than blindly solicit. For example, we should plant more

11、trees and take actions to protect the environment. In addition, we have to control population. Due to excessive population growth, human beings require much more natural resources than before, which lead to excessive pressure on nature. In order to long-term development, the population growth must b

12、e controlled. We all come from nature which is our homeland, so we must try best to protect it. 以自然为题的英语演讲稿3 What is nature Its everything that exists in the world independently of people, such as pants and animals, earth and rocks, and the weather. Now more and more people are focusing on the natur

13、e. It is no doubt that the nature is important to every human being. No nature, no life. Because of the supplies of the nature, we have lived happily for a long time. And we started to gain every thing available from the nature. And this lasted so long a time. Today, people have discovered that the

14、nature around is getting worse and worse. What is threatening the natureAir and water pollution, overharvesting of plant and animal species, overpopulation and so on. Overpopulation is the biggest source of pollution. Lets take overpopulation as an example. What does overpopulation feel likeWhen we

15、move slowly through the city in a tazi. When we enter a crowded slum district. When the temperature is high and when the air is thick with dust and smoke. The streets are crowded with people. The streets seem alive with people. People eating. People washing. People talking. People sleeping. People v

16、isiting each other, arguing and screaming. People relieving themselves. People pushing their hands through the taxi windows, begging. People leading animals. People, people, people, people. As we drive slowly through the crowd, sounding the taxis horn, the dust, heat, noise and cooking fires made it

17、 like a scene from hell! I admit, frightening. To the nature, overpopulation is a big problem. More people, more pollution. And the big population is threatening the nature every second. The rapid rise in world population is not creating problems only for the developing countries. The whole world fa

18、ces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. People in rich countries make the heaviest demands on the worlds resources, its food, fuel and land, and cause the most pollution. A baby born in the United St

19、ates will use in his lifetime 30 times more of the worlds resources than a baby born in India. Unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land, food and fuel, and the future w

20、ill bring poverty, misery and war to us all.For most of the developing countries, it is a good idea to control the population growth. For example, China has carried out birth control for years. And this plan has a great effect on the world population. If the population continues to increase, if the

21、air and water continue to be polluted, if we dont do something to protect wild-plant and wildlife species will be declining. Species and biological communities have difficulty adapting to change. Economic opportunities and the quality of life of future generations are also put at risk. By protecting

22、 nature, we protect ourselves. Lets unite together, hand in hand we stand all across the land. We can make this world in which to live. Hand in hand. Control the population growth. Take good care of our nature. 以自然为题的英语演讲稿4 Suddenly, is unpredictable. Natural disasters is usually fierce, with great
