保护环境初中英语演讲稿1
尊敬的评委老师,各位朋友:
大家好!
放眼望去,有的只是凹凸的地皮,大片大片的树林遭人砍伐,变成人们生活上的木制品。人们只为一己私利,使成群的动物流离失所,奔向它方。这并不是虚假的幻想,这是血淋淋的事实。
曾几何时,世界上大批的动植物遭到灭绝,还有许许多多的动植物濒临灭绝,这都是为什么?这都是因为人类乱伐树木,破坏了生态环境,这才是根本原因。
土地资源是三大地质资源(矿产资源、水资源、土地资源)之一,是人类生产活动最基本的资源和劳动对象。人类对土地的利用程度反映了人类文明的发展,但同时也造成对土地资源的直接破坏,这主要表现为不合理垦植引起的水土流失、土地沙漠化、土地次生盐碱化及土壤污染等,而其中水 土流失尤为严重,乃当今世界面临的又一个严重危机。据估计,世界耕地的表土流失量约为230亿吨/年。
有人认为酸雨是一场无声无息的危机,而且是有史以来冲击我们最严重的环境威胁,是一个看不见的敌人。这并非危言耸听。随着工业化和能源消费增多,酸性排放物也日益增多,它们进入空气中,经过一系列作用就形成了酸雨。
赤潮虽然自古就有,但随着工农业生产的迅速发展,水体污染日益加重,赤潮也日趋严重。我国自1933年首次报道以来,至1994年共有194次较大规模的赤潮,其中60年代以前只有4次,1990年后则有157起。石油类污染对水质和水生生物有相当大的危害。漂浮在水面上的油类可迅速扩散,形成油膜,阻碍水面与空气接触,使水中溶解氧减少。油类含有多环芳烃致癌物质,可经水生生物富集后危害人体健康。二氧化硫主要由燃煤及燃料油等含硫物质燃烧产生,其次是来自自然界,如火山爆发、森林起火等产生。二氧化硫对人体的结膜和上呼吸道粘膜有强烈刺激性,可损伤呼吸器管可致支气管炎、肺炎,甚至肺水肿呼吸麻痹。短期接触二氧化硫浓度为0.5毫克/立方米空气的老年或慢性病人死亡率增高,浓度高于0.25毫克/立方米, 可使呼吸道疾病患者病情恶化。长期接触浓度为0.1毫克/立方米空气的人群呼吸系统病症增加。另外,二氧化硫对金属材料、房屋建筑、棉纺化纤织品、皮革纸张等制品容易引起腐蚀,剥落、褪色而损坏。还可使植物叶片变黄甚至枯死。
保护环境,人人有责。

Water is the source of life
Earth looks like a big blue marble; from high above the Earth and from the moon, the planet gleams and shines. The blue water in the oceans and seas of the Earth makes a dramatic image.Water is the source of this beauty and the source of life on Earth. It is the reason people can live on this planet. Water is everywhere. Water is in rock deep under the ground, in natural holding areas.In a real sense, water keeps Earth alive. The last drop of water will be the world's human tears.

Therefore, I appeal to you here: "Take action at water saving

Everybody Can Help The Environment
We all know Tagore.This famous Indian poet once said, “Life is given to us, and we earn it by giving it.” As the saying goes, nature is given to us, and we earn it by contributing to it. However, most people nowadays just want to ask for more from the nature. In fact, they do very little contribution to the nature. Therefore, the environment around us is becoming worse and worse.
Do you often use batteries? Then do you know it takes 50 times more energy to make them than they produce? And just one simple battery can pollute as much water as a person can drink in his whole life. The facts and figures are amazing. So would you please try to use batteries only when it is necessary? If possible, give the used ones to the recycling companies so that they will be made into new ones and won’t be able to pollute the environment any more. Sometimes we become complacent when it comes to recycling, but when you speak in terms of actual facts and figures that everybody can understand, people become much clearer about the problem.
We, as school students, can also join in recycling activities to protect the environment. For example, our class set up a recycling center beside the back door, it is very useful. It is used to collect the waste paper and plastic bottles. In the past, our classmates used to throw all of these into the trashcan. At the very beginning of this collecting activity, it was not so warm-welcomed. Later, more and more people were influenced by the others and joined this collecting activity. Gradually, all the students in our class form a good habit to protect the environment. All of us will now put away the reusable things instead of throwing them into the trashcan.
We should always remember in our mind that protecting the environment is our duty that we can never neglect. Finally would you please let me end this speech with a little poem, “Be kind to the river. Be good to the trees. Smile at the sunshine, and bow to the breeze. Be friendly to nature, and nature will be friendly to you!”
