保護環(huán)境初中英語演講稿1
尊敬的評委老師,各位朋友:
大家好!
放眼望去,有的只是凹凸的地皮,大片大片的樹林遭人砍伐,變成人們生活上的木制品。人們只為一己私利,使成群的動物流離失所,奔向它方。這并不是虛假的幻想,這是血淋淋的事實。
曾幾何時,世界上大批的動植物遭到滅絕,還有許許多多的動植物瀕臨滅絕,這都是為什么?這都是因為人類亂伐樹木,破壞了生態(tài)環(huán)境,這才是根本原因。
土地資源是三大地質(zhì)資源(礦產(chǎn)資源、水資源、土地資源)之一,是人類生產(chǎn)活動最基本的資源和勞動對象。人類對土地的利用程度反映了人類文明的發(fā)展,但同時也造成對土地資源的直接破壞,這主要表現(xiàn)為不合理墾植引起的水土流失、土地沙漠化、土地次生鹽堿化及土壤污染等,而其中水 土流失尤為嚴重,乃當(dāng)今世界面臨的又一個嚴重危機。據(jù)估計,世界耕地的表土流失量約為230億噸/年。
有人認為酸雨是一場無聲無息的危機,而且是有史以來沖擊我們最嚴重的環(huán)境威脅,是一個看不見的敵人。這并非危言聳聽。隨著工業(yè)化和能源消費增多,酸性排放物也日益增多,它們進入空氣中,經(jīng)過一系列作用就形成了酸雨。
赤潮雖然自古就有,但隨著工農(nóng)業(yè)生產(chǎn)的迅速發(fā)展,水體污染日益加重,赤潮也日趨嚴重。我國自1933年首次報道以來,至1994年共有194次較大規(guī)模的赤潮,其中60年代以前只有4次,1990年后則有157起。石油類污染對水質(zhì)和水生生物有相當(dāng)大的危害。漂浮在水面上的油類可迅速擴散,形成油膜,阻礙水面與空氣接觸,使水中溶解氧減少。油類含有多環(huán)芳烴致癌物質(zhì),可經(jīng)水生生物富集后危害人體健康。二氧化硫主要由燃煤及燃料油等含硫物質(zhì)燃燒產(chǎn)生,其次是來自自然界,如火山爆發(fā)、森林起火等產(chǎn)生。二氧化硫?qū)θ梭w的結(jié)膜和上呼吸道粘膜有強烈刺激性,可損傷呼吸器管可致支氣管炎、肺炎,甚至肺水腫呼吸麻痹。短期接觸二氧化硫濃度為0.5毫克/立方米空氣的老年或慢性病人死亡率增高,濃度高于0.25毫克/立方米, 可使呼吸道疾病患者病情惡化。長期接觸濃度為0.1毫克/立方米空氣的人群呼吸系統(tǒng)病癥增加。另外,二氧化硫?qū)饘俨牧?、房屋建筑、棉紡化纖織品、皮革紙張等制品容易引起腐蝕,剝落、褪色而損壞。還可使植物葉片變黃甚至枯死。

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. We Chinese are one of the 12 water-poor countries, as people waste, water less and less. However, there are many waste of water, for example: some of the children bought water gun filled with water shooting water everywhere; there are some students hand-washing after washing bowls, or not turn off the faucet, waste a lot of water... .... Yunnan-Guizhou Plateau, where the recent prolonged drought, making survival of the population there is facing a serious threat to address this problem, we in China 1.3 billion to develop awareness of water conservation. 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!”
