环境保护所要解决的问题大致包括两个方面的内容,一是保护和改善环境质量,保护人类身心的健康,防止机体在环境的影响下变异和退化;二是合理利用自然资源,减少或消除有害物质进入环境,以及保护自然资源(包括生物资源)的恢复和扩大再生产,以利于人类生命活动。下面给大家分享一些关于高中英语环保演讲作文5篇,供大家参考。
What is nature? It's 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. Let's 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 taxi's 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 world's 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 world's 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 don't 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.
Let's 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.
Good afternoon, my honorable judges, ladies and gentlemen and fellow contestants:
I feel so happy to have the chance to make a speech. The title of my speech is Protect the Environment, Protect Ourselves. I hope you will like it.
Everybody knows waste paper and used coke cans are discarded everywhere. You might have seen plastic bags flying in the sky and getting caught in the trees when the wind blows or maybe you have seen old cans floating in the rivers and polluting the water. Our environment is the place in which we live, but it is being ruined by us.
There is a story about house and trees. It is said that a man’s house was surrounded by a lot of trees. Though the wind was strong, that man could have a good rest under the trees. How comfortable the life was! One day, that man wanted to enlarge his house, so he cut down all the trees. Then the autumn came without the protection. The strong wind blew the roof of the house into the sky. The whole house was gone with the wind. What a pity! But that’s the price people have to pay for destroying in the ecology balance. People shouldn’t be short-sighted. Protecting the environment is everyone’s task.
As you know, there are four kinds of pollution. They are air pollution, water pollution, waste pollution and noise pollution. But what can we do to solve the pollution? I think, firstly, we can make cars that don’t pollute the environment. We can ask companies to use modern clean technology. In some big cities, we can limit the number of cars. Secondly, we can try to use less water and make sure that we do not pollute the water. We can tell factories that they are not allowed to pour waste water into the lakes and rivers. Thirdly, we should not throw rubbish in parks and cities. We can pick up rubbish if we see it. We can put more rubbish bins in our parks and cities. Fourthly, we can live far from the noise and make the laws to limit the noise.
The air, water and the whole atmosphere directly influenced our lives, such as the air, people may cough and it will lead to cancer. So we must try our best to keep the world clean and tidy. To reach it, I want to put forward three points to everybody---Point 1: don’t spit and liter; Point 2: don’t draw on the wall; Point 3: clean the streets every day.
In order to make the environment clean, let’s join our hands together to make the world better.
Thank you!
DEMAND for graduates in the UK with skills related to sustainability is booming. Academia is waking up to the need to train specialists in green architecture, chemistry and engineering.
Dean Millar founded the world’s first ever BSc course in Renewable Energy at Exeter University after working as an industry consultant.
He said: “A lot of companies were complaining that there was a lack of bright young people suitably trained to work in the renewables business.”
Now his course has around 90 students learning the ins and outs of biomass, tidal, solar and offshore wind power.
Their career prospects are incredibly bright. Employment opportunities are not just limited to the energy sector, but segue into the regulatory and, increasingly, investment sectors as well.
“The big boys are moving in. The returns to be had are significant, especially in terms of wind development,” said Millar. “Financial firms need expertise across the board so they can make sensible investment decisions.”
Students on York University’s Master’s course in Green Chemistry are ideally placed to take advantage of the growing demand in industry for graduates with waste minimization skills.
Professor James Clark is founder of York’s Green Chemistry Centre for Excellence and the world’s leading green chemistry journal, Green Chemistry. He said: “We are now talking to producers of automobiles, electronics, furniture and pharmaceuticals, people who need to use chemistry but don’t think of themselves as chemists.”
As waste production legislation becomes increasingly strict, the traditional emphasis on making as much of a chemical as possible is shifting towards minimizing the waste that process creates. “A lot of chemicals are made from petroleum, but we are developing sustainable ways to make carbon, typically from biomass such as dead plants and trees,” said professor Clark.
All of last year’s graduates quickly found employment, some receiving multiple job offers in a variety of different fields.
Li Li, a 26-year-old Chinese postgraduate student, graduated from York in 20_. She said:
“I hadn’t heard about green chemistry in China. It was a new area and I was curious. Now the government back home needs people who know about these principles.”
Deep in the heart of Wales, 400 students at the Centre for Alternative Technology’s (CAT) Graduate School of the Environment are busy designing and building everything from high insulation wood housing to wind power turbines. With energy costs rising, building firms are increasingly looking to minimize the energy wasted heating and lighting homes, a service CAT students are well-equipped to provide.
A new institute is being built to meet the burgeoning demand for places and a distance learning facility will be launched next September so foreign students can complete CAT courses from home.
The expertise being taught on these courses is essential to a continually expanding range of companies and government authorities. Yet there is a larger goal at stake; the students are at the forefront of the battle against climate change. In the words of Dean Millar, “If we’re going to save the planet, we need to start turning these people out in big numbers.”
he world we live in is becoming more and more intolerable because of environmental destruction. For example , forest destruction results in decrease of planting land and unpleasant weather. In addition, man is faced with problems of water pollution and air pollution.
A lot of measures have been taken. Planting trees helps improve and beautify the environment. Besides, laws concerning environmental protection have been put into effect and achieved good results.
However, the problem of environmental protection remains far from being solved. On the one hand, the environment pollution and destruction are getting worse and worse in the modern world. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. In a word, there is a long way to go before we enjoy a clean and comfortable world.

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。
