We live in the world every day. We eat food, drink water, wear clothes, watch TV, use computers and so on. We are producing waste every moment.
Generally speaking, there are four sorts of waste. They are material waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort of waste one by one.
Material waste: it means the waste of substance or things from which something else can be made. For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. At last, they become waste. For example, when people finish reading newspaper, the paper will become waste. When the glass is broken, it also becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Once it is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they are convenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenience plastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are white. Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. It’s true that rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a long time and becomes old. The old tyres become waste because it can’t break down by nature. This is really a big problem.
Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution. Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment. However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.
各位同学们：
今天我要讲的是保护环境的演讲稿，题目是《保护环境是不容推御的责任》
让我们想一想，自从人类诞生以来，一切的衣食往行及生产、生活有哪一样离得开我们生存的环境，我们生活在地球上，然而地球并不是有我们生存，还有很多很多的动物植物，所有生物的生存，又有哪一样离得开地球上的大气、森林，海洋、河流、土襄、草原呢?地球就是由所有的生物组成了错综复杂而关系密切的自然生态系统，这就是人类赖以生存的基本环境。
然而，保护环境的演讲稿，就是这样供人类生存的环境，却总是被人类自己所破坏。人类把文明的进程一直滞留在对自然的征服掠夺上，却从来不曾想到对哺育人类的地球给予保护和回报，我们人类在取得辉煌的文明成果的同时，对自然的掠夺却使得我们所生存的地球满目疮疤，人口的增长和生产活动的增多，也对环境造成冲击，给环境带来压力。
地球上人类、生物和气候、土壤、水等环境条件之间存在着错综复杂的相互关系，就好比我们人体的各个器官、各种机能之间都是需要保持平衡是一样的，你想想，我们人类身上的某个器官坏了，人就会生病，就会痛苦不已，其实地球也是如此，一旦失去了生态平衡，便会产生种种不良后果。因为人类的侵害，如今地球面临了很多的环境问题，比如气候变暖，臭氧层空洞，酸雨，有毒废弃物，野生生物灭绝，以及大气、水污染等等，这些都是令人类头疼不已的事情，保护环境的演讲稿，推荐一篇小学生安全演讲稿。
保护环境，人人有责，虽然我们现在还只是个学生，没有能力去改变那些环境不问题，但是我们可以从小事做起。春天到了，植物开始生长，我们可以积极参与植树节，保护身边的花草树木。除此之外，我们还要爱护身边的环境卫生，遵守有关禁止乱扔各种废弃物的规定，把废弃物扔到指定的地点或容器中，避免使用一次性的饮料杯、饭盒、塑料袋，用纸盒等代替，这样可以大大减少垃圾，减轻垃圾处理工作的压力。这一切，看起来不是很平凡的事情吗?只要我们愿意，很轻松就能完成，很轻松就能参与到保护环境的重大工作当中。
亲爱的同学们，你还在犹豫什么呢?从此刻起，就伸出你的手，伸出我的手，一起去爱护环境，保护环境，我相信，有了每一个人的参与，我们的校园更美丽，我们的祖国更美丽，让我们时刻谨记保护环境是不容推御的责任。
我的演讲完毕，相信大家!您此刻正在百范文网阅读演讲稿《保护环境的演讲稿：保护环境是不容推御的责任》
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?
同学们：
大家好!
今天我要演讲的题目是保护环境。
保护环境是每个人的责任，社会无论如何发展，人类都得承认一件事实，那就是大自然是人类的母亲，我们呼吸一口空气，喝的每一滴水，都离不开自然。人类赖以生存的星球只有地球。
可是，人类像一个贪婪的孩子，只顾索要，不管回报，以至于现在的环境伤痕累累，场次以来，受伤的必将是我们人类自己……
瞧!如果不保护环境，大自然母亲也将会发怒，比如20xx年的5。12大地震，日本大地震，泥石流灾害等，在这过程中，有多少人失去的亲人，失去了无法估量的财产，这不是大自然对人类的惩罚吗?
我们身边触目惊心的事例历历在目，如;路边的小树被折，小草被践踏，小花被采摘，难道他们不痛，不伤心吗?乱砍滥伐，无节制的开采矿产资源。人们就是这样，无所事事的破坏生态平衡。作为小学生，我们应该从身边做起，从小事做起;保护花草树木，不乱丢垃圾，不使用一次性筷子，尽自己一份微薄之力。
在此我呼吁大家;请保护环境，只有这样才是最终保护了人类自己!因为地球只有一个，人类不能克隆。
我的演讲到此结束谢谢大家!
Stepping into the new century environment pollution has become more serious than ever since. There are different kinds of pollution. Such as water pollution air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. where all these pollution comes from? To a large extend the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel people cut down trees and dig more corals. But the growing needs for energy are hardly to meet. Countless private cars on the street the gas stations are short of gasoline even the government has raise the price so many times in order to control the needs of gasoline but it’s still not working. Overusing the natural resources has already affected the ecological balance. However the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.
The government should put forward some more strict laws to prevent the environment from being further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again. Only in this way our earth could be a better place to live in.
protect the environment?
Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.
Ladies and gentlemen,
I am honored to stand here to share with you on such a important subject as climate change.Yes ,it is global warming .
Let me give you two phenomenons.
Here is the first one. More and more people used to be using air condition ，but how many people ever thought whether this new ,hobby will bring side-effects or not? Maybe just few people. In fact, the side-effect is apparent. The emissions of gases exhausted from air conditioning contain a lot of methane .which could cause global warming. By the way, air conditioning will waste a lot of electricity .
The second one is about the increasing amount of cars. According to the statistics, in 21st century, there are 7 millions cars in the world, a large amount of exhaust gases has seriously influenced us, such as: cough, throat inflammation.
This two phenomenons are just few part of reason which change our environment badly. There are many other reasons.
In nearly 100 years, the average global temperature experienced twice fluctuations which is “cold-warm-cold-warm”. Generally, it is the trend that global climate is becoming warmer and warmer . In 1980s,global temperature rised apparently. According to Chinese scientists, the average temperature in China has risen by 1.1 degrees
protect the environment.
Good environment can make people feel happy and fit . To improve the environment means to improve our life.
We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.
Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.
尊敬的老师，亲爱的同学们：
大家好!今天是6月5日—世界环保日。今天我要演讲的题目是《保护环境卫生，人人有责》。
在我们的日常生活中，生活环境是十分重要的，但人们常常不重视这一方面。使清澈见底的小溪变成了肮脏的水沟;郁郁葱葱的大森林变成了落光头发的老爷爷;鸟语花香的村庄变成了山洪爆发的地方……这一切都是由人类的一举一动所造成的。
前几日，我到广场上骑自行车，发现不远处的草坪中有许多的白色垃圾，真是不计其数!可见我们的环保意识还不够强。说小一点儿，影响该地区的形象;说大一点儿，这是影响我们国家的形象啊!
作为一名少先队员，作为一名小学生，我们也应该保护环境，从我做起，从小事做起，从力所能及的事情做起。当别人随手扔下垃圾的时候，你会去捡起;当别人践踏草坪的时候，你会去阻止;当别人在破坏树木的时候，你会去教育……
曲格平曾经说过：“没有一个清洁美好的环境，在优裕的条件也毫无意义。”南丁格尔也曾说过：“人生欲求安全，当有五要：一要清洁空气;二要澄澈饮水;三要流通沟渠;四要扫洒房屋;五要日光充足。”我相信，在我们的共同努力下，我们的家园一定会成为一个美丽、健康、幸福、和谐的世界!
让我们从小事做起，从我做起，爱护花草树木，爱护环境，让明天的世界变得更加美好!
谢谢大家!
In recent years there has been a marked growth of fire accidents in big cities of our country. Almost every day we see fire engines rushing through the streets. Fires have not only resulted in heavy economic losses but also injured and killed many people.
What are the causes of fire accidents? Most of the fires are brought about by carelessness and violation of fire safety regulations. Others are due to the poor quality of home electrical appliances. By the way, some people don't know how to use them properly. Besides,there are quite a few businesses which focus so much of their attention on profits that they tend to neglect and even ignore fire precautions.
In my opinion, in order to prevent fires we should first of all foster people's sense of fire prevention. The second thing we have to do is to increase the number of professional fire fighters, to whom regular training courses should be offered. Finally, we are to improve the existing fire engines and add more fire facilities to high-rise buildings. In this way, a reliable fire prevention system will be formed.
尊敬的领导、同志们：
大家好!
当前人类社会已经进入十分发达的工业文明时代了，人类在不断的进步，我们人类已经征服了地球，成为地球上的主宰，现在人类又开始征服太空，希望能够在太空中找到自己更好的归宿。殊不知，我们的地球已经被我们人类破坏的不能再破坏了，保护环境已经不是一时间的事情了，需要全世界人民的一起努力，我们的地球才会回到曾经的样子。
其实，真的说不清是从哪一天开始，纯净辽阔的大海里产生了星球史上最早的生命精结绿藻群带;其实，真的说不清是从哪一天开始，奔腾不止的黄河岸边出现了现代人铭记的祖先蓝田人类;其实，真不说清是从哪一天开始，大地欣然地托起了普罗米修斯窃取的火种，从而宣告了文明初始而完整的诞生;其实，真的说不清是从哪一天开始，人类不仅征服了自然，而且开始学会向自然索取曾饱受天灾的赔偿资源潜能。
于是，人类的文明史上有了结实的木椅、精刻的木阁;而孕育出人类的原始丛林却在伤心地萎缩;于是，人类的文明史上有煤炭、石油、地热;而承接着人们疯狂攫取的大地却在悄悄地下沉、裂变、陷落;于是，人类文明史上有了林立的厂房、烟囱、化工车间;而那片曾经
温柔的晴空，却正在被黑的、黄的、灰的污染杀手将臭氧层残忍地撕破。
终于，人类的文明史上有了微观得可怕的氢能、中子能、原子能，而从此，文明之邦的土地上不知多少因亲离友散而痛苦凄厉的哭声。
假如，历史真的是一张翔实无疏的时间表，我只想查一查人类究竟是从什么时候起开始学会把作为星球上的最高智能生物的特权发挥得如此淋漓尽致，却轻而易举地忘记，自然一样会再次惩罚我们。
因为英国人无规划地扩大工厂，排放废气;于是大自然便在1873年、1883年、1892年发生了三次伦敦毒雾事件侵吞一千八百人作为赔偿。因为日本人在足尾铜矿疯狂采挖，任排污水，于是大自然便让400平方公里的良田变为荒园以示惩罚。因为美国人在狭长的平原地带连建了铁、硫、铜三大工厂，于是大自然便在1948年10月27日用毒雾遮笼整个山谷作为报复。 因为苏联人肆意将粉尘毒气排入空中，于是大自然便让加里宁格勒普降黑雪，让1960年两次黑风暴席卷俄罗斯大平原作为警告。因我们过分索取森林，于是大自然便以黄河两岸土流失区达百分之七十四，一次性水灾毁坏千万亩沃土作为代价。
然而，人类不知为何却固执地抛开了这些暗示，仍在一天天、一年年执迷不悔地犯着同一种错误，重演着同一种悲剧;终于，1952年一次伦敦毒雾事件死亡一万两千余人是前三次总和的十倍;美国河谷带十年肺气肿死亡率上升为以前的百分之六百三十;苏联仅水污染一项每年损失六十亿美元，这些加速上升的数字已迫使人类不得不承认，曾被征服的自然现在却无法控制，中东北非的富饶土地变成极目无边的沙漠;墨西哥的丰足粮仓变成了荒芜的侵蚀斜坡;我国凉山彝族自治州的青山绿水被泥石流淹没。
正如恩格斯指出的：我们不要过分陶醉于我们对自然界的胜利，对于每一次这样的胜利，自然界都报复了我们。每一次胜利在第一步确定取得了我们预期的结果，但第二步、第三步却有了完全不同，出乎意料的影响，常常把第一步结果取消了。
我们常常是在有意与无意之间，把地球推向了生命的底线。让地狱迸爆出的烈火肆意侵舐着每一点绿色，让所有的生灵在灼伤的苦痛中哀叹。
我们经常是在有意与无意之间，打开了潘多拉的魔盒，然后面对因贪婪的欲念铸下的过错，无奈地看着盒中升起的狰狞的黑烟在大地与天空间弥漫。
我们常常是在有意与无意之间，撞响了天王手中的金玉琵琶，然后忍受绵延的噪音，却不知该怎样办。我们常常是在有意与无意之间，使海面漂浮的石油粘住了海鸥的翅膀;使果林里的农药残害了弱小的生灵;使夜空里再也看不见清亮的星星，使明净的湖水变成了一点就着的油坑。
我无以否认，人类正在夜以继日创造文明;可是朋友，你能否认人类正在夜以继日地毁灭文明吗?
我们只有这么一个美丽的星球，我们的先人和我们的后人都注定要在这里生存。为了调色板上的蓝色能属于天空和大海，白色能属于瑞雪和浮云，黄色能属于阳光和谷堆，绿色能属于山川和森林;让你、让我共同伸出手来，承下昨天交给我们的这份责任。用诚心、汗水、智慧化合成的清泉，刷洗这个世界，赎去我们曾犯下的罪过，交还给自然一个真正的文明。 我们的地球是最美丽的，可是我们不能让我们的地球毁在我们的手中，这样的话，我们的后代只会说我们的目光短浅，没有给他们留下一个美丽的地球，这才是我们一直以来都在痛心的事情，我们的后代还要继续生活在地球上，可是我们给他们留下的是什么，是很难被我们救回的地球生态环境，以后的道路还要怎么样，我们不知道，可是我现在对大家说，保护环境、人人有责!
