英语环保主题演讲稿篇1
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.

once man did not have to think about the protection of his environment. there were few people on the earth, and natural resources seemed to be unlimited.
today things are different. the world has become too crowded. we are using up our natural resources,and polluting our environment with dangerous chemicals. if we continue to do this, human life on earth will not survive.
we realize that if too many fish are taken from the sea, there will soon be none left. yet,with modern fishing methods, more and more fish are caught.we know that if too many trees are cut down, forests will disappear. yet, we continue to use powerful machines to cut down more and more trees. we see that if rivers are polluted with waste products, we will die. yet, waste products are
still put into rivers.
we know that if the population continues to rise at the present rate, in a few years, there won't be enough food.what can we do to solve these problems?
if we eat more vegetables and less meat, there will be more food available. land for crops feeds five times more people than land where animals are kept.
our natural resources will last longer if we learn to recycie them.
the world population will not rise so quickly if people use modern methods of birth control.
finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

everyone!now i want to talk about a beautiful world!
when i was young,i always dreamed that i lived in a beautiful country. there were many flowers and trees around our city.we could hear the birds singing and see the children dancing. the streets were clear and the the air was very fresh! how nice it was! as is known to all , we have a beautiful world .we can see the sun shining. we can see the moon in a full view. we can see the birds flying in the sky. we can see the horses running on the plain. but that only was a dream of mine! the world is not as beautiul as before, for human beings have brought a disaster to the world.how i wish that it would be come true! so i think we should do something to protect our environment.
however, 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.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.
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 pollution. finally, those who destroy the environment intentionally should be severely punished. we should let them know that destroying environment means destroying mankind themselves.
of course ,not only government but also everyone should make a contribution to protect the environment.have you ever thrown any litter onto the groundhave you ever drawn pictures on public wallshave you ever cut down treesif your answers are ＂no＂,it means that you have already helped protect our environment. protecting our environment is everyone＇s business.
thank you !

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.

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 20xx. 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.”

we live in the world every day. we eat food, drink water, wear clothes, watch tv, use computers and so on. we are producing waste every moment. generally speaking, there are four sorts of waste. they are material waste, organic waste, inorganic waste and poisonous & harmful waste. now, we are going to talk about each sort of waste one by one. material waste: it means the waste of substance or things from which something else can be made. for example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. at last, they become waste. for example, when people finish reading newspaper, the paper will become waste. when the glass is broken, it also becomes waste. nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. once it is broken, it becomes waste. the rate of using plastics is increasing day by day. people use plastic bags because they are convenient. when they get home, they throw the plastics way, paying no attention to the environment. the more convenience plastics brings to us, the more plastic waste is produced. this is called “white pollution” as most plastics are white. some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. it’s true that rubber plays an important role in our life. however, it also brings us some trouble when it has been used for a long time and becomes old. the old tyres become waste because it can’t break down by nature. this is really a big problem.
