演讲环境作文篇1
各位老师、同学们:
早上好!
在人类生存发展,曾遇到过许多的敌人:战争、灾荒、瘟疫、这每一种敌人都曾使人类付出过惨重的代价。然而,今天人们面临的的敌人,已不是战争、疾病、天灾以及瘟疫,而是无处不在的环境问题!
大气污染超标、温室效应增强、臭氧层被破坏、土地沙漠化、水资源污染严重、海洋生态危机、绿色屏障锐减、物种消失加剧、垃圾威胁人类、人口增长过快,这些世界性的环境问题,究其原因,都是人类在发展经济的过程中,对自然资源和生态环境的不合理利用和破坏所致。
这一切的现实,让每一个关心祖国前进和发展的中国人深感痛心。保护环境,利在当代,功在千秋,这是一项崇高而伟大的事业,更是中华民族千秋万代利益所在。
千里之行,始于足下。保护环境,建设美好家园,要从我做起,从小事做起。心动不如行动。只要我们确实落实我们的言行,不乱丢垃圾,不浪费粮食,限度地节约用水,节约能源,节约用纸,拒绝使用一次性的“白色污染物”,乘公共交通旅行,多栽树种草,保护好野生动植物资源,自觉地遵守各项环境法规。那么,我们头顶上的天空将会变得更蓝,身边的河水会变得更清,空中的鸟儿将会鸣叫得更加响亮,生活在其中的人们将会变得更加健康快乐。
我很高兴地经常看到许多同学在校园的各个角落捡拾果皮纸屑;用自己的双手去保护和营造优美的校园环境。但是,我们也经常看到一些我们不愿意看到的情景:操场上、楼梯上、走廊上有纸屑、食品袋;雪白的墙壁上被印上手印、脚印和球印;教室里、走廊上留有难以清除的口香糖的.污迹……这说明,我们的习惯还没有很好的养成。
同学们,我们是21世纪的主人,具有环保意识是现代文明人的标志。我们要有时代感责任感,要心系全球,着眼身边,立足校园。“勿以善小而不为,勿以恶小而为之”,让我们积极行动起来,从身边的小事做起,培养环保意识,养成环保习惯,创造我们美好的校园,塑造我们美好的灵魂!
演讲环境作文篇2
你知道我的家乡在哪吗?你猜对了,就是美丽的绿城—南宁。
南宁街道的绿化非常茂盛,种花地方五颜六色,种树木和草的地方是一片绿油油。还有很多人周末只放一天假,可是他们不怕辛苦,为了保护环境,就带自己的子女到邕江边捡垃圾,让他们的子女有环保意识。
你知道3月12日是什么节吗?对了,就是植树节。每到这一天,就有很多人去义务植树,为的就是保持生态平衡。人们渐渐有了环保意识,上街买东西都用用布袋装,吃东西不用一次性筷子,上班工作大多数都使用单车或电动车也乘公车,乘公车可减少车尾气的排放。人们为了保护环境插了标语,比如:“南宁是我家,保护环境靠大家。”“别踩我,小草也会疼”“保护环境从我做起,从每个人做起,从身边小事做起。
接下来说一说为什么要保护环境?因为以前人们不懂得保护环境大量使用汽车,造成太多尾气排放破坏了臭氧层,那么北极的冰就会融化,水就会淹没整个地球。所以,从现在开始我们就要保护环境,节约用电,买家店买一级能秏的,或二级能耗,空调加的也是不生产臭氧的雪种。以后,我们要多坐电动车,多坐单车,少坐汽车,减少对地球的危害。
保护环境,从我做起。
演讲环境作文篇3
亲爱的老师、同学们:
大家好!
我是来自xx班的xx,此次有幸能给大家进行演讲,我真的感到无比的荣幸,感谢各位老师和同学给我的支持和帮助!
那么进入正题,此次,我给大家带来的演讲主题是——“珍惜资源,保护环境”!
说到这个话题,相信同学们都不会陌生。我们同生活在一个地球村,环境和资源都是我们赖以生存的资本。保护和珍惜,都是我们生活中本应该做到的责任。
但随着工业和科技的发展进步,我们人类在发展和生活中消耗资源的速度以及地球环境的恶化也越发的严重!如今,我们不仅要面对风沙侵蚀和部分地区的水资源短缺,甚至连全球的气温都在不断的.升高!这正是因为我们过度开发和开采却没有有效保护生态的证明!再回头看,尽管我们倡导文明环保,学习各种勤俭节约的知识!但在我们的生活中,甚至校园里都仍然存在着浪费资源以及一些不文明的行为存在!乱丢垃圾、乱扔纸屑,甚至还有“长明灯”和“长流水”等浪费资源的行为!更别提在我们在食堂中浪费的饭菜了!
同学们,让我们好好回想一下在校园内的生活,我们是否经常会发现一些被丢弃在花坛中的垃圾,是否能听到水龙头没关导致水流不停的“哗哗”声!各位,这正是因为我们没能遵守文明和环保的意志所导致的结果,我们现在浪费和污染的,其实正是我们自己的未来!
绿水青山并非一朝一夕能长成的,但美好的未来绝对无法离开自然给我们的这些恩惠!同学们,家园的环境与我们息息相关。或许对于整个地球的环境来说,我们整个xxx学校都是微不足道的一个小点,但只要我们从自己开始努力,就能从一个小点开始,一点点的改变世界!点与点连成线,线与线又最终会构成一幅美丽的画卷!但这一切,都是从最初的小点开始的!为此,让我们从现在开始,重新审视自己的生活,改善自己的习惯,让水不再白流,让垃圾不再落地!我们可以做到,我们必须做到!
如今,环保和节约已经是迫在眉睫的问题,让我们一起奉献自己小小的力量,为重建家园的美丽和清新做出一份努力的!我相信,未来的我们一定不会为自己的努力感到后悔,我们一定能见到更美的蓝天!
谢谢大家!
演讲环境作文篇4
尊敬的老师们,亲爱的同学们:
大家好!
早晨出行时,虽鼻子并不十分灵敏,闻不见什么特别异味,可那久高不下的pm2.5指数却让我知道,早上pm2.5已高达500多!这是一种有害健康的颗粒状灰尘,而500多的指数已是大幅度在损害健康状况!单从汽车释放的尾气便可看出来,在那乌黑的气体中得有多少损害健康的物质!
对于这种情况,人们虽然在心里心知肚明,可谁又会去做什么呢?大多数人还不是眼看着空气一天天的变差,自已却不停的买车,扔垃圾?从来不曾想到要为保护环境做点什么,嘴上谈论却并不付诸于行动,又有什么用呢?
而做一个环保的人其实并不困难。身边的一切,只要想去节约,环保,都是很容易做到的。家里可能会买瓶装洗手液,但用完就把这样一个瓶子扔掉了,这实在是太过可惜的`事情。把瓶子洗净留下来,下次就买袋装的洗手液,只不过多了一道事情,就能让这件事情充满环保,何乐而不为呢?
这些事情都是小事,看似不起眼,可做了便是环保。如果每个人都能环保,哪怕只是做些小事,都是在为我们生存的环境出一份力。
河流污染,导致饮用水有毒;汽车数量的极速增加,使空气质量越来越差。这些事情的造成,是因为虚荣心,利益,还是别的什么?化学工厂把化学用的废材料为了省事,一股脑的倒进了人们日常食用的河水里,却因为省的再把这些材料进行处理而心里在沾沾自喜。
他们在倒的时候想起过会引起河流污染吗?人们在买车时,是否考虑过汽车会污染环境,而且,还是自己生存的环境?
所以,保护环境刻不容缓,让我们把环保看成一件每个人的身边事吧。环保,从现在开始!
谢谢大家!
演讲环境作文篇5
through the changes in the ways of making a living in a family over several generations, man has been warned against waste of natural resources and emphasizing the urgent need to preserve these resources. ever since man appeared on the earth, man's survival has been heavily relied on nature. almost everything we use in our everyday life comes from notate, ranging from the food we eat, the water we drink, to the wood which is tm'ned into furniture.with the development of technology and population growth, the amount and range of materials used has increased at an alarming rate.however, natural resources are not inexhaustible. some reserves are already on the brink of exhaustion and there is no hope of replacing them. the widespread water shortage is an example in point. if man continued to squander natural resources with no thought for the future, the later generations would be in danger. it is up to us to take effective measures before the situation gets out of hand.
演讲环境作文篇6
chinahas a very long and brilliant history whose people are so friendly and hospitable. but i am wondering why some people pay such little attention to the environment and nature. in many places of the countryside rivers have become stinking sewers and brooks have disappeared. heaps of garbage obstructs the scarce flow of dirty water. the grounds are littered with plastic bottles and bags. people are cutting down trees even though it is illegal. in some towns rubbish is hidden behind walls. garbage cans are often of little use making cleaners must rush all day long and also by night to clean the rubbish. this lack of consideration for nature in general is extremely detrimental to children’s education tochina’s image to public health to tourism and to the future.chinais the common treasure of all chinese and we should live up to be a member of this big family a descendant of 5000-year-plus ancient civilized country. i think the environment must absolutely be strictly protected by all means. this protection should go at the same pace as the marvelous development of the nation.in this respectgermanyis a rare model and leaves me a very deep impression. after you have an exciting tour around in this country for a week or so it is unnecessary for you to polish your leather shoes. personally first of all the strong awareness of people’s environmental protection; then the advanced technology applied in the field of preserving the nature; we can learn form others in building china into one of the most environmentally friendly places in the world.
演讲环境作文篇7
各位老师、同学:
大家好!
今天,我要演讲的内容是“保护环境,人人有责”
同学们,我们曾经有一个美丽富饶的家园,那时候,草木苍翠,绿树成荫,百花盛开,百鸟争鸣,小溪缓缓地流动着,唱着悦耳的歌,空气是十分清新的,带给人一种神清气爽的美感,地球妈妈,也正为我们带来快乐呢!
可是,你知道吗?在美丽的环境中,灾难也不知不觉地降临了。现在,由于人类对环境不够珍惜,随心所欲地滥伐树木,滥建厂房,导致各种环境问题接踵而至:森林退化,沙尘暴扬,水土流失,洪水肆虐,火灾频发,噪音刺耳,臭气熏天,酸雨赤潮,废渣成堆……且据现在统计,南极的臭氧空洞正逐步增大,地面紫外线辐射增强,皮肤癌发明率上升;1.2亿人口生活在浑浊的空气里;12亿人口生活缺水;12%的哺乳动物跟11%的鸟类濒临灭绝;每年地表土壤流失200亿吨;森林以每年450公顷的速度小时……
这些一次又一次的灾难还不足以警示我们,保护环境已刻不容缓了吗?所以,为了我们的地球跟我们自己,请保护环境吧!地球是我们的家,既然我们在地球上安居乐业,就要好好的保护环境,维护生态平衡。让我们号召身边的人,一起为保护环境做出贡献吧!保护环境,人人有责,让我们先从身边的小事做起吧!
我的演讲完毕,谢谢大家!
演讲环境作文篇8
the quality of human life has improved greatly over the past few centuries, but earth is being harmed more and more by human activity. as we develop our technology, we demand more from our planet. eventually, this will harm people as well. our planet gives us everything we need, but natural resources are not endless. strip mining devastates whole regions, leaving bare and useless ground. deforestation removes old growth trees that can't be replaced. too much fishing may harm fish populations to the point where they can't recover. we are too careless in taking what we want without giving anything back. there are more people than ever, living longer that ever. so is it any surprise that many areas suffer from too much development? anyone living in or near a city has experienced "urban sprawl". there is a new shopping area on every corner and new houses, townhouses and apartments everywhere. traffic gets worse and worse because planners can't keep up with growth. keeping up with human demand is hard enough. environmental concerns come in last. with growth comes pollution. companies and communities dump waste into water. landfills are full of trash. emissions from factories pollute the air. barrels of industrial waste and worse, radioactive waste, have no safe place to go. if we're not careful, we can harm our planet beyond repair. people need to respect the earth and try to preserve it. if we don't, what kind of future will we have?
