关于环保英语的演讲稿篇1
we have only one earth. but now,the environment becomes worse and worse.
as you know,there's no enough clean water for people. so many of them lose their lives because of water. in a lot of countries, people have to cut trees for living. so there's nothing to keep water from running away. also we have polluted the land, the river and the air. so we have to face more and more floods and droughts .
it's time that we must do something useful to protect our environment. we can plant trees and take good care of them. we can save the water and ask our parents to do so. we can't throw any litter onto the ground and we should collect them for recycling.
if we take good care of our earth today,it will be more beautiful tomorrow.

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.

ladies and gentlemen,
i am honored to stand here to share with you on such a important subject as climate change.yes ,it is global warming .
let me give you two phenomenons.
here is the first one. more and more people used to be using air condition，but how many people ever thought whether this new ?hobby? will bring side-effects or not? maybe just few people. in fact, the side-effect is apparent. the emissions of gases exhausted from air conditioning contain a lot of methane (这里可以停顿一下)which could cause global warming. by the way, air conditioning will waste a lot of electricity .
the second one is about the increasing amount of cars. according to the statistics, in 21st century, there are 7 millions cars in the world, a large amount of exhaust gases has seriously influenced us, such as: cough, throat inflammation.
this two phenomenons are just few part of reason which change our environment badly. there are many other reasons.
in nearly 100 years, the average global temperature experienced twice fluctuations which is “cold-warm-cold-warm”. generally, it is the trend that global climate is becoming warmer and warmer . in 1980s,global temperature rised apparently. according to chinese scientists, the average temperature in china has risen by 1.1 degrees
centigrade in the last 5 decades. it is higher than the reported global average. we are seeing more frequent bouts of extreme weather in many parts of the country. for example, last spring, the most severe drought in 50 years hit northern china affecting the livelihood of 4 million people. environmental damage and climate change is a reality for us. out of the world?s most polluted 20 cities, half are in china,70% of chinese rivers are polluted . china has become the largest carbon emitter of the world.
it is really thought-provoking(发人深省). who pays for it ? first,as the pace of human high-tech development process goes quiker and quiker, the side-effects with the science development reflected, global warming is one example. more and more greenhouse gases with the development of economy are being discharged into the air.about 70% of the greenhouse gases has been composed of carbon dioxide,which is considered as one of the greatest causes of global warming . it has harmful effects,causing the sea level to raise and many natural disasters to strike. on the other hand , scientists in one wave after another try to awaken us to the growing threat of global warming.but many coutries tend to turn a deaf ear(充耳不闻) to the scientists?warnings.in fact,the earth?s atmosphere is definitely being warmed and the problem is largely man-made. a wise way is that we should get moving to protect ourselves. so the public demand that all nations should taket strong measures to prevent the increase of the earth?s temperature.
in my opinion, it is the high time for us to take action. in order to save the earth, we should try to do things below: no air conditioning, use recycled paper,abandon meat food, don?t use plastic bags,take a bus.it is little drops of life.as long as everyone takes action, it will be a powerful strength to rescue our planet. all countries are supposed to take the legislative initiative as soon as possible.only in this way can the global warming be put under control.

dear teachers and students,hello! today, my topic is "protecting the environment and everyone isresponsible".
throughout the ages, earth's mother has nurtured countless generations ofchildren with sweet milk. she was beautifully decorated by her children. now,however, the human race tormented her for its own sake. man has only one earth;and the earth is facing a severe environmental crisis. "save the earth" hasbecome the most powerful voice of people all over the world.
students, we are the small masters of the earth, environmental awareness isthe important symbol of modern people. we should establish a sense ofresponsibility in the times. focus on the world and focus on the campus. to pickup the scraps of paper with a bent waist; don't throw about; take a few moresteps, don't pass through the green belt, trampling green space. "it isincumbent on all of us to save resources and protect the environment. we need tostart from now, start from our side, start small. through our efforts, the skyof the motherland is bluer, the land is greener, the water is clearer. whetherit is the past, present, or future, whether it is family, country, or the world,the environment is always our friend, to be kind to our friends, to be kind toourselves.
"there is only one earth", let us protect our homeland together.
关于环保英语的演讲稿篇5
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 beunlimited.today things are different. the world has bee too crowded. we areusing up our natural resources,and polluting our environment with dangerouschemicals.
if we continue to do this,human life on earth will not survive. werealize that if too many fish are taken from the sea,there will soon be noneleft. yet,with modern fishing methods,more and more fish are caught.we knowthat if too many trees are cut down,forests will disappear. yet,we continue touse powerful machines to cut down more and more trees. we see that if rivers arepolluted with waste products,we will die. yet,waste products are still putinto rivers.
we know that if the population continues to rise at the present rate,in afew years,there won't be enough food.what can we do to solve these
problems?ifwe eat more vegetables and less meat,there will be more food available. landfor crops feeds five times more people than land where animals are kept.ournatural resources will last longer if we learn to recycie them.the worldpopulation will not rise so quickly if people use modern methods of birthcontrol.
finally,if we educate people to think about the problems we shall have abetter and cleaner planet in the future.
