每一个人都拥有一个家，地球是大家共同的家。曾经的地球是多么美丽，多么洁净啊，我不想把曾经的美丽停留在图片中，停留在书本里，不想生活在被大自然惩罚的可怕噩梦里。同学们，老师们，让我们行动起来吧！从身边的小事做起，从身边的一点一滴开始做起：不乱丢果皮、不随地吐痰、减少汽车尾气排量。如果每个人都做到这几点的话，我们的世界将会更加美好！

我的演讲结束了，谢谢大家！

演讲保护环境的作文篇2

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！

pollution is harmful to human beings. polluted water causes many kinds of diseases such as diarrhea, enteritis, etc. and sometimes these diseases even take man’s life. dirty air or air-borne garbage causes stinging eyes and running nose. pollutants are destructive. they cause runs in nylon stockings and crack rubber tires and they eat away at stone and rust iron. measures have been taken to control pollution. in recent years, legislative steps have been introduced to control pollution. rivers are being cleaned. air is purified, and pollutants are being trapped before they are poured out of chimneys. however, pollution problems have not been completely solved. pesticides are widely used almost everywhere. they pollute soil, water and food. they have the power to make our streams fishless and our gardens and woodlands silent and birdless. some factories are still using air as a dumping place for wastes. some lakes are still dirty. quite a few chimneys are still pouring smoke into air and noise pollution remains serious.

演讲保护环境的作文篇6

environmental problems are becoming more and more serious all over the world. with the development of industry and agriculture, cars make great noises and give off poisonous gas. trees on the hills have been cut down,and waste water is being poured continuously into rivers. furthermore,wherever we go today, we can find rubbish carelessly disposed. the whole ecological balance of the earth is changing. massive destruction of environment has brought about negative effects and even poses a great threat to man's existence. we must face the situation that exists and take actions to solve our environmental problems. for instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. we hope that all these measures will be effective and bring back a healthful environment.

演讲保护环境的作文篇7

敬爱的老师，亲爱的同学们：

你们好！

我们生活在这个美好的地球上，地球妈妈创造了我们人类，还无私的为我们奉献，提供资源。而我们人类却惨无人道的折磨它，它的慷慨奉献却是人类的浪费。因此，为了让地球更美丽，为了让我们能够在更好的环境中生存，我们要精心保护地球，保护地球生态环境！

一、保护树木

绿色是时尚的代名词，绿色是树的`代名词，绿色是小溪的欢歌，绿色是花儿的枝叶，绿色象征着勃勃生机。树是人类的朋友，它奉献氧气吸入二氧化碳，为人类净化空气，保持生态平衡，抵御沙化、风尘、赤潮。但是，人们怎么报答它的？滥砍滥伐，是沙漠面积渐渐增大，绿洲随着减少，人类生存的范围也就缩小了。试问那些滥砍滥伐的人，你们的良心还过得去吗？

二、保护水资源

水，滋润万物，与人们的生产生活息息相关。水是甘甜的。但有时又是苦涩的；水是宝贵的，但有时它又泛滥成灾；水是清冽的，但在一些地方它却变得污浊不堪；一切生物都离不开水，但在一些特别需要水的地方，它却变得那样吝啬……水，是生命之源，是任何物质都不可替代的。没有水就没有生命，更谈不上什么文明和发展。当前，由于世界人口的剧增、人类的过度索取和浪费，以及工业污染等原因，世界淡水资源越来越匮乏，人类正面临着严重的水危机。我们作为小学生应该做些什么呢？

三、保护野生动物

犚吧动物是自然生态系统的重要组成部分，在维护自然生态平衡中的作用及其在社会生活中的地位日益受到广泛重视。保护野生动物，不仅关系到人类的生存与发展，也是衡量一个国家、一个民族文明进步的重要标志之一。全社会要积极行动起来，不乱捕、不滥杀、不滥食野生动物，保护野生动物从餐桌做起，做一个文明守法的公民。

看了以上内容，你还有什么犹豫的，让我们大家一起自觉保护环境，自觉爱护环境，自觉绿化环境，改善我们的生活环境，创造美好的未来！
