第一篇:绿色环保小短文

Protection of the 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.保护环境

过去,人们不必担心保护环境的问题。因为那时地球上人口稀少,自然资源似乎取之不尽。

如今,一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源,有毒化学制品的使用也正污染着环境。如果我们继续这样下去,地球上的生命将不复存在。

我们都知道如果从海里捕捉太多的鱼,海里就不会再有鱼了。但是,现代化的捕鱼技术使得捕鱼量越来越大。我们都知道如果砍伐太多的树木,森林就会消失。但是,我们仍旧使用强大的机械砍伐越来越多的树木。我们都知道如果河水被废弃物污染的话,我们只有死路一条。但是废弃物仍然源源不断地进入河里

我们知道,人口继续照现在这个速度增长的话,不出几年,就会发生食物短缺。我们该如何解决这些问题呢?

如果我们多吃蔬菜,少吃肉类的话,我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。

如果我们学会再利用的话,自然资源就能持续更久。

如果人们使用现代化的生育控制方法,世界人口就不会增长如此迅猛。

最后,如果我们能够教育人们都意识到这些问题的话,未来我们就会有一个更好、更洁净的星球。

打好环保比赛、创建绿色北京

尽管2008北京奥运会离我们还有3年之遥,但有一项规模宏大的特殊比赛已经拉开了序幕。这场比赛的参加者并非来自世界各国的体育选手,而是身处北京的每一位公民,比赛的场所就是我们身边的街区小巷。我想大家已经想到了我所说的这项特殊比赛,这就是“创建绿色北京、保护美好环境”。那么在这场环保大赛中,我们究竟要与

谁一比高低?是繁华现代的洛杉矶、风光迷人的悉尼、还是古老神奇的雅典?都不是!比赛的对手就是我们自己,就是我们自身淡漠的环保意识。

几年前有幸在美国加州度过的一段时光,既让我享受了那里宜人的环境,更让我领略了当地人民高度的环保意识。每当说到城市环保,我的眼前总会浮现出加州那蔚蓝的天空、明媚的阳光、碧绿的草地以及嬉戏在树枝间的松鼠、彩蝶和百灵鸟。

记得刚到美国时,常去爸爸工作的美国地质调查局玩耍,每次均能看到许多人骑自行车上下班,而其中一位满头白发的骑车老人,引起了我的好奇。我问爸爸,“那个爷爷为什么总骑车上班,是不是没钱买车?”爸爸笑道:“没钱买车?嘿,说出来吓死你,他可是世界上顶级的大科学家。要论钱,他可以买一个车队呢。” “那他咋不买车呢?骑车多累呀!” “他有车,但平时除非下雨或购物,一般不去开。在美国有许多人都是环保主义者,为了节约能源和减少汽车尾气对大气的污染,他们用实际行动倡导人们尽量少开车。而我们所居住的这座美国城市,还特别将每年的5月19日定成了'骑车上班日',以支持和宣传这种有效的环保行为。”

后来,我还在经常的搭车出行中获知了他们的另一件环保趣事:在美国的许多州,政府为了鼓励大家多坐公交车或几人合用一辆车,以节省能源和缓解交通压力,在城市内一些主干道路上开辟有专门的'钻石车道',只有乘坐了二人或二人以上的车辆才从此通过。美国人民

这种自觉的环保意识和政府有效的环保措施使我从内心对他们充满了敬佩。并深刻地影响了我的环保理念。

回国后,常常有人问我:“美国好吗?”我总会脱口而出:“确实好!最好的是环境。”说句真心话,回国三、四年,美国那边同学和老师的面孔已经逐渐模糊,但加州那宜人的自然环境,却每每清晰地浮现在我的眼前,成为我最深的记忆和期盼故地重游的缘由,也成了我心目中北京环境的蓝图。2008奥运会为我们倡导和实施北京的环保提供了契机,北京能否有朝一日也拥有象加州那样美丽的环境?答案是肯定的。但需要我们以真正的环保之心和切实的环保行动去一步一步地实现。

从现在开始,如果每一位有车的朋友一星期可以少开

一、两次车,每个让家长用车接送的同学一周能主动让家长少接送一两趟而改乘公车或骑自行车,我们就会有拥有更多的蓝天……。只要我们每一位北京市民都能够自觉的从身边的环保小事做起,加州的蓝天、白云和绿草地就会在北京安家,美国的松鼠、彩蝶和百灵鸟就会来北京落户。

涓涓细流可以汇成滔滔江海,片片绿叶能够造就莽莽森林。只要我们每一位北京市民都拿起手中的环保之笔,在我们所处的街头巷尾,为北京这幅美丽而古老的画卷添上自己的一抹绿色,就能使北京掩映在绿色的海洋中。让我们一起行动起来,用我们集体的力量来打赢这场环保之赛,向全世界展现一块最大的金牌,这就是“绿色北京、精彩奥运”。

Win Competition of Environment Protection for Beijing

Although the 2008 Olympics are still three years away, another special competition has already started in Beijing.This time, the competitors are not the athletes from all over the world, but the people living in Beijing.The special competition is not held in a stadium, but in every street and every corner of Beijing.I suppose some of you may have already guessed what the special competition is.Yes, it is the competition of protecting our environment and creating a green Beijing for the 2008 Olympic Games.Someone may ask who is our rival in this competition? The modern Los Angeles, the charming Sydney, or the historic Athens? No, none of them.The real rival is ourselves.It is our bad habits of neglecting to protect environment in our daily life.Several years ago, I was very lucky to have an opportunity to live in the United States for about two years.I not only enjoyed the beautiful environment there, but also appreciated the American people's active way of protecting

their environment.Now, whenever the environment protection is mentioned, a beautiful view of California will arise in my mind: white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and small animals playing happily among the trees.I remember that at the beginning of my coming to America, I often went to my father's working place, the United States Geological Survey, to have fun.Each time I found a lot of people riding bicycles to their offices.Among the cyclists, an old man with white hair attracted my attention.Curiously, I asked my father,“ Why does the old man ride his bike to work every day? Doesn't he have enough money to buy a car?” Father laughed, “No, not because of money.Actually, he is one of the greatest scientists in the world.He can afford to buy a motorcade if he likes.He is just an environmentalist and usually doesn't drive unless going shopping, or in bad weather.In America, there are a lot of environmentalists, who actively protect their environment.For example, in Palo Alto city we are living now, there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars”.Later, I also learnt another interesting fact of environment protection there.In some states of America, in order to decrease air pollution, save energy and reduce traffic jams, state governments encourage people to take buses to work or to share a car among several people.They even set special “diamond lanes” in some main streets, which are only for the vehicles with 2 or more people.The positive actions of American people and the effective measures the American government takes in environment protection fully won my respects and deeply affected my consciousness in environment protection.When I was back in China, people often asked me: “ What do you think of America?” I always bolt out:“ Wonderful, especially the beautiful environment.” Frankly speaking, after several years, the faces of my American teachers and friends have gradually faded away from my mind, but the blue sky, green grass and lovely animals in California often arise in my mind, and became my dream of visiting there again.The 2008 Olympics provide us with the opportunity to publicize and practise environment protection in Beijing.Is it possible for Beijing to Is it possible for Beijing to become as beautiful as California? The answer is “yes”, but the dream needs every Beijing citizen's full support and active moves to accomplish.From now on, if every student who is driven to school can take bus or ride bicycle to school once a week, if every car owner goes to work in a car pool once a week, we can make a difference.If everyone can actively protect the environment in our daily life, the blue sky, green grass and lovely animals in California will appear in Beijing.Tiny streams can combine into a vast ocean, small trees can together be an immense forest.Beijing is often described as a beautiful and aged picture.If every Beijing citizen adds a trait of green on the picture, the whole Beijing will become an ocean of green.Let us unite together to win the competition of environment protection in Beijing, and present the world a big gold medal.That is “Green Beijing, Great Olympics ”

Nature--Overpopulation 环保英语演讲稿

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.A beautiful world 环保英语演讲稿

Hello:

everyone!Now I want to talk about a beatiful 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 counld hear the birds singing and see the children dancing.The streets were clear and the the air was very fresh!How nice it was!But that only was a dream of mine!How I wish that it would be come true!So I think we should do something to protect our environment.Everyone should make a contribution to protect the environment.Taking care of our environment is very important.Wherever you live,you can do something around your neighbourhood.Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls?Have you ever spat in a public place?Have you ever cut down trees?If your answers are “No”,it means that you have already helped protect our environment.It is our duty to keep our envionment clean and tidy.You might ask yourself,“Have I ever picked up some rubbish and

thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?”If your answers are“Yes”,it means that you have already done something useful to improve the environment.Now I want to say :Let`s do our best to make our world more beautiful!

第二篇:英文环保小短文

Once the human beings didn’t think about the environment

protection There were few people on the earth, and the natural resources seemed to be Inexhaustible.Nowdays, the situation is changed he world has become too crowded The desertification all over the world is threatening the human’s living We are using up our natural resources and polluting our environment with poisonous chemicals Water resources are being polluted to different degrees The polluted air is seriously harm to human's health Due to the environment destruction, the creature on the earth dies.If we continue to do this, human beings on the earth will not be able to survive.It's time for us to protect the environment.How to protect the 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.We should go on foot or by bike.Don't throw the waste batteries anywhere If we take good care of our earth today,it will be more beautiful tomorrow.

第三篇:绿色环保小知识

[绿色环保小知识] 1.尽量搭乘公交车,吸清净多走路、骑脚踏车有益人体健康,每辆车少开1公里,可避免0.61公斤的废气产生。2.停车惰转熄火,少废气每部车一年节省油耗约1.25公升,减少2.7公斤CO2排放。

3.自备水壶水杯,少开销一个瓶子重复使用20次,可节省1/3~1/4的CO2排出量。

4.使用省电灯泡,多能源换上省电灯泡,每年可减少146公斤的CO2产生。

5.定期汽车保养,多安全随时保持轮胎正常胎压,可提升汽油使用效能多行驶3%公里,每节省3.785公升汽油,可减少19.5公斤的CO2产生。

6.减少车内重量,多省油若减少10公斤的杂物重量,一年可减少2.5公升的汽油。只是一个小小的动作哦,你也可以做到

7.利用可再生资源—别等到能源耗竭的那一天

人类目前使用的能源 90%是石油、天然气和煤。这些燃料的形成过 程需要亿万年,是不可再生的资源。太阳能、风能、潮汐能、地热能则 是可再生的,被称为可再生能源。人们把那些不污染环境的能源称为“ 清洁能源”。8.珍惜纸张——就是珍惜森林与河流

纸张需求量的猛增是木材消费增长的原因之一,全国年造纸消耗木 材1000万立方米,进口木浆130多万吨,进口纸张400多万吨,这要砍伐 多少树木啊!纸张的大量消费不仅造成森林毁坏,而且因生产纸浆排放 污水使江河湖泊受到严重污染(造纸行业所造成的污染占整个水域污染 的30%以上)。

9.选无磷洗衣粉——保护江河湖泊

我国生产的洗衣粉大都含磷。我国年产洗衣粉200万吨,按平均15% 的含磷量计算,每年就有7万多吨的磷排放到地表水中,给河流湖泊带来 很大的影响。据调查,滇池、洱海、玄武湖的总含磷水平都相当高,昆 明的生活污水中洗衣粉带入的磷超过磷负荷总量的50%。大量的含磷污 水进入水源后,会引起水中藻类疯长,使水体发生富营养化,水中含氧 量下降,水中生物因缺氧而死亡。水体也由此成为死水、臭水。

10.选绿色包装——减少垃圾灾难

每人每天丢掉的垃圾重量超过人体平均重量的五六倍。北京年产垃 圾430万吨,日产垃1.2万吨,人均每天扔出垃圾约1千克,相当于每年堆 起两座景山。我国目前垃圾的产生量是1989年的4倍,其中很大一部分是 过度过包装造成的。不少商品特别是化妆品、保健品的包装费用已占到 成本的30%—50%。过度包装不仅造成了巨大的浪费,也加重了消费者的 经济负担,同时还增加了垃圾量,污染了环境。绿色环保小知识 绿色环保小知识

1.电池的组成:干电池、充电电池的组成成分:锌皮(铁皮)、碳棒、汞、硫酸化物、铜帽;蓄电池以铅的化合物为主。举例:1号废旧锌锰电池的组成,重量70克左右,其中碳棒5.2克,锌皮7.0克,锰粉25克,铜帽0.5克,其他32克。

2.电池的种类:电池主要有一次性电池、二次电池和汽车电池。一次性电池包括纽扣电池、普通锌锰电池和碱电池,一次性电池多含汞。二次电池主要指充电电池,其中含有重金属镉。汽车废电池中含有酸和重金属铅。

3.电池数量:DC、MP3等数码产品在以超猛的速度发展,而且都在使用着电池,电池的使用量在迅速增加,如果再不付诸行动的话,电池山的现象迟早会发生。

废旧电池的危害

1.废旧电池的危害性 一粒纽扣电池可污染60万升水,等于一个人一生的饮水量。一节电池烂在地里,能够使一平方米的土地失去利用价值,所以把一节节的废旧电池说成是“污染小炸弹”一点也不过分。

我们日常所用的普通干电池,主要有酸性锌锰电池和碱性锌锰电池两类,它们都含有汞、锰、镉、铅、锌等各种金属物质,废旧电池被遗弃后,电池的外壳会慢慢腐蚀,其中的重金属物质会逐渐渗入水体和土壤,造成污染。重金属污染的最大特点是它在自然界是不能降解,只能通过净化作用,将污染消除。

废旧电池的危害主要集中在其中所含的少量的重金属上

金属种类危害的表现

过量的锰蓄积于体内引起神经性功能障碍,早期表现为综合性功能紊乱。较重者出现两腿发沉,语言单调,表情呆板,感情冷漠,常伴有精神症状。

锌的盐类能使蛋白质沉淀,对皮膜粘膜有刺激作用。当在水中浓度超过10-50毫史/升时有致癌危险,可能引起化学性肺炎。铅:铅主要作用于神经系统、活血系统、消化系统和肝、肾等器官能抑制血红蛋白的合成代谢过程,还能直接作用于成熟红细胞,对婴幼儿影响甚大,它将导致儿童体格发育迟缓,慢性铅中毒可导致儿童的智力低下。

镍粉溶解于血液,参加体内循环,有较强的毒性,能损害中枢神经,引起血管变异,严重者导致癌症。

它在这些重金属污染物中是最值得一提的,这种重金属,对人类的危害,确实不浅,长期以来,我国在生产干电池时,要加入一种有毒的物质——汞或汞的化合物,我国的碱性干电池中的汞的含量达到1-5%,中性干电池为0.025%,全国每年用于生产干电池的汞具有明显的神经毒性,此外对内分泌系统、免疫系统等也有不良影响,1953年,发生在日本九州岛的震惊世界的水俣病事件,给人类敲响了汞污染的警钟。

重金属污染,威胁着人类的健康,人类如果忽视对重金属污染的控制,最终将吞下自酿的苦果,因此,加强废旧电池的回收就日显重要了。

有关资料显示,一节一号电池烂在地里,能使1平方米的土壤永久失去利用价值;一粒纽扣电池可使600吨水受到污染而无法饮用,相当于一个人一生的饮水量。电池里包含了汞、铅、镉等多种对自然环境威胁巨大的物质,若将废旧电池混入生活垃圾一起填埋,或者随手丢弃,渗出的汞及重金属物质就会渗透于土壤、污染地下水,进而进入鱼类、农作物中,破坏人类的生存环境,间接威胁到人类的健康。

环境保护,从我做起,其实并不难,您可以从下面几点着手:1注意节约用电,离开房间时关上电器,拔下插头。2每年参加植树造林活动,并在自己的居室内外种植花草。3尽可能用节能灯代替普通灯泡。4不购买、品尝野生动物,劝亲友不要到野外捕食飞食走兽。5尽量以步代车或骑自行车。6不要购买一次性物品,如筷子、剃刀、纸杯等。尽量选择用可回收利用材料包装的饮料。7购物时自己携带购物袋,不使肜不可降解的塑料袋。8节约用水,刷牙时关闭水龙头,洗脸、洗澡、洗衣物的水可以冲洗厕所或拖地。9避免使用杀虫剂和除草剂,尽量施用有机肥料。10购买无磷洗涤剂和有绿色标志的产品。11回家充当环保卫士,监督父母有无影响环保的行为,依法监督,举报破坏环境的行为。
