亲近大自然的英语演讲稿亲近大自然的英语演讲稿1 We often say that the earth is our 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 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 be controlled. We all come from nature which is our homeland, so we must try best to protect it. 亲近大自然的英语演讲稿2 Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down, and waste water is being poured continuously in to rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence. We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the hazard of pollution and soon. We hope that all these measures will be effective and bring back a healthful environment. 亲近大自然的英语演讲稿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 nature. 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 nature around is getting worse and worse. What is threatening the nature? Air 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 like? When we 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 visiting 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 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 faces 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 States 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 will 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 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 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. 亲近大自然的英语演讲稿4 Mother Nature is an exquisite and complex life-system. Its charm appears in the trees, stream, soil, insects, moss and fungus, all the things on th
