中考英语作文关于环境保护汇集20篇

每当我看见垃圾桶旁的垃圾，就会想起一件事来。 那是上月的一天下午我正兴致勃勃的走在街上，看见一个叔叔在抽烟，抽完一根丢在地上，一点也不在乎，也没有害羞的感觉。又开始抽另一根烟，边抽边跟一个人讲话。一副得意忘形的样子。我走上前去勇敢地对那位叔叔说：你不能乱仍垃圾，破坏环境。叔叔听了凶巴巴地说：少管闲事，滚开。我听了就走开了，他第二根烟抽完后，干净的地面被破坏了。这时，一个清洁工走来了，他理直气壮地说：你应该往垃圾桶里丢。 他反而气势汹汹的说：我丢了就应该你扫。

清洁工说：如果全世界的人都像你这样，世界就成了垃圾世界，你愿意生活在又脏又臭的世界里吗？如果我们都像那位叔叔一样，地面就会到处都是垃圾，蚊子、苍蝇满天飞舞，疾病就会像妖魔的影子一样在人群游荡。 全球变暖给我们敲响了警钟，地球正面临着巨大的挑战。保护地球，就是保护我们的家。让我们行动起来，保护环境，挽救地球家园的命运，维护人类的一个继续生存的未来。

依稀记得以前某一年的一天，奶奶带着我和堂弟去老舅舅家。途中，必须要经过一条河。那条河很长很宽。但是，却很臭，就连河水也是黑色的，在途中。奶奶告诉我们姐弟俩说那条河以前的河水很清，味道也不是那么难闻。还听奶奶说那里有很多条小鱼，他还在那里面捞鱼，游泳呢，可是不知道怎么会演变成那样子可见我们人类当时是怎么对待那条河的。这条河之所以变成现在这个样子，也是由于我们人类破坏生态环境所引起的。我一边去往老舅家，一边在想为什么有关部门不来处理这个问题呢？为什么还要维持现状呢？实在是太不负责任了！

再次去老舅家，在途中必须要经过的那条臭水河居然变得那样清澈，也没有那样难闻的味道了！听奶奶说是因为有关部门把那条河的污染治理了，才会变成现如今的样子。再次想想，他们还是有保护生态环境的意识嘛！可是，我却还是没有看到有小鱼在水里面自由自在地游。看来，我们还是要多多保护生态环境。

现如今，我们能做的，就是不再随便像以前一样什么东西也往河里面扔了。记得有句话几乎人人都知道：保护环境，人人有责。

如果我们不保护生态环境，也会危及我们人类自身的生存。所以我们一定要记住那句我们几乎人人都知道的：保护环境，人人有责。一定要切记，切记。

“保护环境，人人有责。”这是连幼儿园小朋友都耳熟能详的一句话。但是，人们却没有理解它的真正内涵，保护环境，是我们每个人都必须要做的，也是理所当然要做的，这并不是领导，扫地工人的事，这是我们全人类都要做的事。

因为现在的环境已经不容乐观，再这样下去，后果将不堪设想。就拿家乡的那条河来说吧，原本河边长满了绿草、花朵，河水也清澈见底，还能看见几只小鱼小蟹。小时候，我舅舅还带我来游过泳，但，现在呢?采砂机一来，河水就变得浑浊不清。原本长在河边的小草小花，一个个都垂着头，苦着脸，好像在说：“这可恶的采砂机，害得我们的生命之源——水都变得肮脏了，唉——”还有，农民们开辟的水沟里的水也不能用了，因为这混杂了泥沙的水显然不利于庄稼生长，这就苦了农民们，要把原来的水沟堵起来不说，还要从自己家里带水来，浇灌庄稼。你看，就因为采砂，弄得那么多人麻烦，虽然你们是赚钱来养活家人，但是你们为什么一定要把这么清澈的河水弄成这样?这到底该怪谁?

因为我知道现在大气污染大体是汽车尾气造成的，所以我专门调查了一下汽车，真是不查不知道，一查吓一跳!全世界目前竟然拥有11亿辆车!按照正常行驶来算，每辆汽车每天排出约24kg的废气，也就是说，全世界每天会排出264亿kg废气，等于2640万吨!你自己想想看，这是有多恐怖啊，一股废气扑面而来……恐怕不被吓死也要被熏死了吧。所以，大家要少开车，多骑车，绿色出行，才能使我们的环境更加美好!

塑料袋，是我们生活中很常见的物品，它轻巧，简洁，还方便，深受广大市民的喜爱，但是，在背负美誉的同时，它也有个不好听的外号，名叫：白色垃圾。没错，塑料袋虽然集众多优点于一身，但，它有个致命的缺点：会污染环境!丢一个塑料袋会污染0.6平方米的土地，按照平均每个人丢一个塑料袋计算，宁海每天就会有60万个废塑料袋，就算被扫掉一半，还是有18万平方米的土地被污染。请问，把自己称作宁海人的你，有没有干过这样对不起宁海的事?千万不要说没有，我们所有人都干过，我们现在所能做的，就是不要再扔塑料袋了，宁海的土地，没有多少啊!

“保护环境，人人有责。”我希望大家能真正做到这一点，不要理解错其中的含义，不要以为扔一个塑料袋没什么了不起，土地是大家的，不是你一个人的!不要再执迷不悟了!

Now, "environmental protection" has become a global focus. But to truly protect the environment, we must start from ourselves and start with the small things around us.

One day, I went to play in the small river in the park. A little boy wanted to throw a fresh bottle into the river. I looked at it and said, "no matter what, Im going to play. If I take care of him, I wont be able to play." But at this time, one is old man on a fishing trip saw the little boys behavior quickly held out his hand to stop a small boy, and said to the boy: "child, dont throw rubbish into the river." The little boy listened and put down the bottle and said to the old man, "whats the big deal? Besides, this is a bottle, not a garbage." The old man listened and was not angry. Smiled and said to the boy, "son, you dont understand. You dont see it as a bottle, but it will also be like other garbage pollution water. We cant drink clean water. Moreover, the trash can is over there, a few steps away." The little boy was speechless to the old man. He said "thank you" to the old man and ran to the trash can.

I listened to that thought, "thats right. When we want to throw fruit peel, tend to throw the rubbish casually into the trash can outside, and ignored. In fact, as long as you stretch out his hand, will be thrown into the trash can. Sometimes, you can throw some wrapping paper with a, then a walk it. Later, you said cant find the trash can. In fact, trash can in a few steps away." These little things can reflect a persons moral character and whether he loves the environment around him.

Protect the environment. Its all about us. Everyone has to do their part. This will make our home more colorful!

20xx，崭新的开始，在除旧迎新走亲访友的同时，你有没有让你的身边多一些低碳和环保呢？

谁都知道，全球温室效应是多么可怕，它就如同一个魔鬼正慢慢地在吞噬地球。《2012》这部电影已经告诉我们世界末日的恐怖，这一次空前绝后的大灾难，足以把人来几千年的灿烂文明毁于一旦，这就是人类破坏大自然的后果。要阻止这种结果，只有保护地球，保护环境。20xx，我们要过低碳生活。

在我们的生活中，低碳环保无处不在。出门时记得关掉电灯，将无家可归的垃圾送回家，或者少开汽车，多走路，少用塑料袋，多用环保袋，这一些微小的举动，都是在为低碳环保做贡献。低碳大到修理地球，搞科学研究做环保设备，小到捡一点垃圾，关掉电灯。我们只需做一些力所能及的事保护地球，保护环境。低碳环保需要人人参与，人人负责，地球一片绿色，还地球一片生机。从崭新的20xx开始，我们人人都要参与进来，保护环境。

地球是我们的家园，地球把保护环境这个重任交给我们，我们就有责任做到，也算是报答地球对人类的养育之恩。

Water is the source of life. Human can not do without water, animals, plants cannot survive without water. We every day to drink water, water, not only we need water, the fish in the water, the crops of the fields, the trees on the hill, and so on all need water. Some people may think so: water is to burn forever, love how how waste waste, this idea is wrong, we should change the idea.

I listen to mama said, in our city the creek, at the time of their small river on the bottom, they often catch fish in the river, catch shrimp, game play, but now is full of rubbish, into a dry river.

Water had a close relationship with each one of us, if there is no water, crops cant grow, we have no food to eat and vegetables, we wash hands, wash dishes, laundry every day... A moment also can not do without water. We cant live without water. Since the water effect, we should save water, form the good habit of saving water, do people go to close the tap, dont throw the rubbish into the river... Keep water clean.

For all of us have a good living environment, let us together hand in hand together, starts from me, start from now, sets up the idea of saving water, protecting water, take good care of water is to take care of ourselves.

In order to our better future, we all work together!

水是生命的源泉。人类离不开水，动物、植物也离不开水。我们每天要喝水、用水，不光我们需要水，水里的鱼儿、田里的庄稼、山上的树木等等都需要水。有的人可能这么想：水是永远用不完，爱怎么浪费就怎么浪费，这种想法是不对的，我们应该改变这种想法。

我听妈妈说，在我们城里的这条小河，在她们小的时候河里清澈见底，她们经常在河水里捉鱼、捉虾、游戏玩耍，可是到了现在却到处是垃圾，成了一条干枯的小河。

水与我们每一个人都关系密切，如果没有水，农作物就无法生长，我们就没有吃的粮食和蔬菜了，我们每天洗手、洗菜、洗衣…一刻也离不开水。如果没有水，我们就不能生存。既然水的作用那么大，我们就应该节约用水，从小养成节约用水的好习惯，做到人走关好水龙头、不把垃圾扔到河里…使水能够保持干净。

为了我们大家有一个良好的生活环境，让我们一起携手起来，从我做起，从现在做起，树立起节水、护水的观念，爱护水就是爱护我们自己。

为了我们美好的未来，我们大家一起努力吧!

How to protect our environment has become one of the biggest problems in the world. We do everything can do a real difference to our environment.

We need to pick up litter around us. Youd better join a programme to protect our environment. You mustnt cut down too many trees. We can protect factories from polluting the rivers.

We can do our best to keep the air clear! I hope everyone do these!

First should realize the importance of protecting endangered animals， to protect endangered animals and habitats， to promote the wildlife conservation and management of the laws and regulations 首要就应认识保护濒危动物的重要性，自觉保护濒危动物及其栖息环境，主动向亲友宣传野生动物保护管理的法律法规。 Second is to use the source of the endangered animals and do not eat， no， not keeping the source of the endangered animals or products， especially in the wild birds， turtles snakes and class 其次是拒绝利用野外来源的濒危动物，做到不吃、不用、不养野外来源的濒危动物或其产品，尤其是野生鸟类、蛇类和龟鳖类。 Last to be destroyed resolutely expose animal resources of the offence， for many endangered animal protection department or unit or fat， with the support of the animal protection administration 最后要坚决揭发破坏濒危动物资源的不法行为，用心为濒危动物保护部门或单位献计献策或捐资捐款，支持濒危动物保护管理工作。

小时候，总喜欢依偎在奶奶怀里听奶奶讲那七彩祥云上的传说。那时的家乡实在美极了，碧水蓝天，绿树环合，即使在夏天最热时也不需要开风扇，那时的我们在树阴下睡觉、嬉戏……。

曾经如此美好，而如今极端天气总神出鬼没。极端天气像吃家常便饭一样频繁—1976年唐山大地震。地震来临之前，天空闪出五颜六色的光，地球已伸出魔爪去拽住那些不择手段破坏环境的目光短浅的小人。2008年汶川地震，死亡人数众多，地震是凶残的恶魔，是无情的吗？不，这是人类自作自受。人类的恶劣行为使地球母亲千疮百孔。2011年夏，皖地区下起了暴雨，雨连续下了四五天，庄稼都被水腐食，这是雨吗，这是雨吗？不，它是地球母亲的泪……

就最近一段时间来看，正值春末夏初，就往年而言，此时已能穿短上衣，但我们还时不时穿褂子。空中还时常弥漫大量沙土。沙漠化日益严重，大气受到污染。就连家乡的曾经那片沃土也已沙化，农作物生长缓慢。这些现象无一不说明环境污染严重，曾经的青山绿水已不复存在。

保护环境迫在眉睫，我们是中华少年，是祖国花朵，是21世纪的主宰。我们应该从小事做起保护环境。如：不乱扔垃圾，不随地吐痰，爱护花草树木等。青少年是社会上最受关注的群体，相信我们的环保意识会让全世界人民行动起来，争做环保小卫士。

为了实现凡水必清，凡地必洁，凡山必绿的愿望；为了让那七彩祥云重现；为了让地球母亲不再满目疮痍，中华少年们，行动起来，让我们携手共建美好地球村。

在我们身边，有这样一些景象：道路上，垃圾四处丢；河流中，废水天天见；空气中，各种“黑龙”肆意排放，臭气熏天…给我们的生活了带来重大的伤害！树木砍光了，只要暴雨来临，水和泥沙形成巨大的泥石流，后果不堪设想；“黑龙”污染蓝天，使人无法正常呼吸；河中废水有人喝了，就引发了水中毒……

难道这些不引人深思吗？在环境污染日益严重的今天，我们又能做些什么呢？在人们随手丢垃圾时，在人们向河里倾倒废水时，有多少人能想到他们毁灭了自己没有？所以，保护环境势在必行！我们必须控制好自己，不乱扔垃圾，就能少一份污染；多种一棵树，多一份绿色；多安装一台废水过滤机，多一份洁净健康；少排放废气，还我们一个湛蓝的天空……让我们的家园干干净净！由此，我郑重、严肃地向还未意识保护环境的人们提建议：

1、以节水为荣，随时关上水龙头，防止滴漏。以节约粮食为荣，尽量地把残留的食物吃完。

2、尽量少用一次性物品，多使用耐用品，自备购物袋或提篮，减少白色污染。

3、不乱丢垃圾和废物品，将垃圾分类投放，变费为宝，使资源循环再生，造福人类。

4、不猎杀珍惜动物和受以保护的动物，关爱与保护野生动植物；植树造林，爱护我们身边的每一朵花、每一片草和树木。

5、不随地吐痰，不随地大小便，不在公共场所吸烟和不制造噪音。

我倡导大家赶快行动起来提高保护环境的意识。为保护环境、造福后代贡献自己的力量。因为，保护环境，刻不容缓！

地球——一个蓝宝石般的星球，他是我们能赖以生存的家园，蓝色的大海，绿色的森林，辽阔的草原，弯弯的小河，蔚蓝的天空，朵朵的白云漂浮其间，描绘出一幅幅清理柔和的画卷，我们是多么的热爱您，我们的地球妈妈！

你们看现在的地球，河里有脏水鱼儿不能快乐的生活。再说被我们砍下的一棵棵大树，我们就不再有新鲜的空气。你们再想想以前的绿草如茵，那里的水那么蓝，树叶那么绿，那景色多美啊，我们为什么要把那么美的景色给毁了呢？

所以，为了我们的地球妈妈，为了我们的共同家园，我们每个人都应该出一份力尽一份心！保护地球，让蓝天更蓝，让白云更白，让鸟儿有可爱的家，让鱼儿游得更加换了，让生命之水长流，让生命之绿永驻，让我们拥有一个共同美丽的家园。

The earth is our home. We must protect it, do not polluted it. To attain low carbon life, actually very simple.

地球是我们的家。我们必须保护它，不要污染它。达到低碳生活，其实很简单。

The scientists found that at least 100 kinds of environmental harm atmospheric pollutants, including so2, nitric oxide, carbon monoxide and hydrogen fluorine hydrocarbon etc on human body has great harm. Industrial production and transportation exhaust gas and dust is the main way if atmospheric pollution. Industrial waste gas of the dust particles would adsorption many poisonous and harmful substances, these pollutants in the atmosphere will produce all sorts of chemical reaction, generate more contaminants, second pollution formed. Atmospheric pollutants in the air accumulated in air quality declining, directly harmful to human health, and make ozonosphere being damaged, cause global warming. Environmental problem has become a global problem, even influenced the survival and development of mankind. Latest research shows that when people in Nineveh is virtuous orchid climate mutation of extinction.

科学家发现，至少有100种不同的环境危害大气污染物，包括二氧化硫，一氧化氮，一氧化碳和氢氟烃等对人体有很大的危害。工业生产和交通尾气烟尘是造成大气污染的主要途径。工业废气的尘埃会吸附许多有毒有害物质，这些污染物在大气中会产生各种各样的化学反应，产生更多的污染物，形成二次污染。在空气中积累在空气质量下降的大气污染物，直接危害人类健康，使臭氧层受到破坏，导致了全球变暖。环境问题已成为全球性的问题，甚至影响到人类的生存与发展。最新研究表明，当人们在尼尼微是尼德兰气候突变的灭绝。

First of all, let me tell you a true event. That is my grandpa with me by boat from yichang to three gorges occurs when one thing.

We all got up that morning, the people on board, is preparing to play water to wash shu. But the faucet for half a day on the boat were down only a few drops of water, one asked, originally is the boat ran out of water! So, we only have stood in long lines, slowly, etc. Although I looked at the ship, the ship under a stream of water, but no one would like to use it. Because the water is so dirty, so HunHuang, who dare to use? Line only slowly, slowly, etc!

Although in the high-speed development of science and technology nowadays, but the impact on our environment. Reduced river pollution, air pollution, the trees, the increasing of the desert... All this is all thanks to the human! Countries while in value, although the world in value, environmental protection, what and how much these things figure up attention? In my opinion, is rare. Although countries in so to speak, but whats the use of words and not of deeds? Did just a few, too! Dont grab from main reason! You see, the Yellow River water is not still contaminated? So the factory does not still pollute the atmosphere? Should grasp, starts from the quality of people, quality grab, but the country and the world to do so? No! Just like to do even when you are done. In the polluted environment is not so?

Animals are extinct, flash floods in explosion, dust storms still exist... It fully shows the environmental pollution! Countries will only go to disaster relief, instead of simply grabbed, will only go to disaster relief, whats the use? Dont all kinds of disaster is still in? We should like lu xun. He had become a is in order to save the Chinese, and he found that it will not solve the fundamental, so he became a writer, to save the people of the spirit. Because this is the fundamental! So, we as the master of the 21st century, you should understand, what is the root of the damage to the environment, from the point to solve it. Work hard -- the 21st century we!

首先，我先给大家讲一个真实的事件。那是我随我的外公从宜昌坐船前往三峡时发生的一件事。

那天早晨，船上的人都起来了，正准备打水洗淑。可是船上的水龙头半天也只下来几滴水，一询问，原来是船上的水用完了!所以，大家只有排着长长的队伍，慢慢的等。我望着船下，船下虽然有着流不尽的江水，但却没有一个人愿意来使用它。因为江水太脏了，是那么的浑黄，又有谁敢去使用呢?只有慢慢的排队，慢慢的等!

如今科技虽然在高速发展，但这影响到了我们的环境。河流污染，大气污染，树木的减少，沙漠的增多……这一切的一切都是拜人类所赐!国家虽然在重视，世界虽然在重视，什么环境保护日，这些事又有多少人影起了注意呢?在我看来，是极少的。国家虽然在这么说，可是光说不做又有什么用呢?做了也只是少数罢了!根本没有从主要原因抓起!你看，黄河的水不是还在被污染吗?工厂不照样还在污染大气吗?抓，就应该从小抓起，从人们的素质，品质抓起，可是国家乃至世界这么做了吗?没有!即使做了也只是做样子罢了。环境不是照样还在被污染吗?

动物还在灭绝，山洪还在爆发，沙尘暴照样存在……这都充分说明了环境还在污染!国家只会去赈灾，而不去根本抓起，只会去赈灾，这又有什么用呢?各种灾难不还是照样在发生吗?我们应该像鲁迅一样。他当初从医是为了拯救中国人，而他发现，这解决不了根本，所以，他当了作家，去拯救人们的精神。因为这就是根本!所以，我们作为21世纪的小主人，就应该明白，什么是破坏环境的根本，从要点去解决它。努力吧――21世纪的我们!

每天，我们都能看见保护环境、爱护环境的标语或行为。但是，我们也能看见不少破坏环境的行为。那么，你是保护了环境，还是破坏了环境呢？

在我家的小区里，我常常看见我小区里的朋友在干坏事，有时她们扯一些花花草草来玩过家家；有时她们在草地上踩来踩去玩游戏；有时她们扯好看的花，然后插在头上；有时她们采一些花瓣，撒向天空，让花瓣掉在自己的身上。这些都是破坏环境的行为。你，做过吗？

她们这样破坏环境，没有人来制止她们吗？不，有些爱护小区环境的大人，就在这时出手了。他们一看见这种行为，就喊这些小孩：别扯花，花是给大家看的，怎么能扯呢？别踩草，草是用来绿化环境的，怎么能踩呢？你们的老师没教过你们要保护环境吗？听到这么一席话，即使是再调皮的小孩，也会乖乖的停止行动。你，做过吗？

保护环境，人人有责。这句话大家都是耳熟能详的了，那为什么，还是有的人管不住自己的手脚，要去破坏环境呢？那是因为，保护环境在有些人的心中，得不到重视。为了我们自己，为了我们的子孙后代，就让我们从自身做起，开始保护环境吧！

Today the quality of our natural environment has become an

important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the

importance of the problems, to use modern methods of birth control, to conserve(保存） our natural resources and recycle（再循环） our products. We are sure that we can have a better and cleaner place in the future.

To Whom It May Concern,

I am writing to express my opinion about the current policy on the official holidays, such as Spring Festival and Golden Week Holiday. As you might know, some believe it is a good idea to enjoy a week-long break. For one thing, it provides enough time for people to refresh their minds and thus to have better preparations for their future work. For another, it will lead to increased tourism and in turn stimulate the development of the local economy.

Truly, the past decade has witnessed many advantages of the official holidays, but we should never ignore its disadvantages. On the one hand, it may lead to heavy traffic in that a large number of tourists go on traveling during the same Period, thus, it might cause air pollution. On the other hand, some tourists, with no awareness of environmental protection, often drop litter at random so that the scenic spots are polluted and thus it demands a tremendous sum of money to eliminate the pollution.

Considering the current grim situation, it is necessary that the authorities concerned should take immediate measures to eliminate these disadvantages. Only through these efforts can we relieve the traffic pressure and at the same time raise people’s awareness of environmental protection.

Yours sincerely,

Li Ming

The sun summoned the planet in the solar system to open an emergency meeting, the theme is to save the planet. The sun to see everyone to the Qi, and clear the clear voice, said: "The stars, our good sister earth has been at stake, the doctor said that her blood is toxins, the body of nutrients is also depleted, in this way "The moon says," In recent years, mankind has mined a lot of oil, minerals, wood and other materials, without protecting the environment, and the earths sister is not sick. "Saturn says" Way, we save the earth together! "" Well! "The stars have promised.

After the stars go back, have heard of human beings looking for a second home, so have made an appointment, never the second home of mankind, have also thrown away the conditions may be human use. For example: the moon threw away the oxygen, Saturn threw away the appropriate temperature, Mercury thrown away ... ... Finally, the human consciousness that the earth is the only human home, carried out to protect the Earth action.

300 years later, the sun also held a meeting, the earth also participated, she looks beautiful, green skin, clean blood, more importantly, she becomes healthy, the moon said: "sister, see you now So happy, I am happy for you.

Friends, the mother of the mothers disease though good, but also need to continue convalescence, and now, let us work together to the earth dressed as the most beautiful planet in the universe.

保护环境英语作文篇3

There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

保护环境作文一：

保护环境，就是保护人类生存的环境，使地球不受到污染。环保意识，从我做起，从点点滴滴做起，从一张小纸屑开始做起。

同学们你们知道吗?“环保”这两个字写起来十分容易，但是做起来却十分的困难。如果我们不做到“环保”，那么也许在五年后，也许在十年后，也许就在未来的某一天，我们的世界又将会变成什么样子的呢?可能是天灰蒙蒙的，到处都可以看到垃圾，每隔三两天就会来一次沙尘暴，就会来许许多多人们无发想象的事情……

我真的不敢再想象下去、再写下去了，这真的太可怕了。但是如今又有多少的人是真真正正地在环保呢?你们看，每个垃圾桶旁都有数不胜数的垃圾。尽管这些垃圾离垃圾桶只有一步之遥，但是四周围来来往往的人没有一个人会将这些垃圾投入垃圾桶内，大家对它都不约而同的做到视而不见;有多少棵树在被砍伐，送往工厂，做成一次性筷子，给那些贪图方便的人使用，做成火柴，做成纸巾……然后到市集上去卖。我想如果这些物品会说话，他们一定会说这么一句话:“醒醒吧!不要再破坏环境了，不要再破坏自己的家园了，你们以后一定会追悔莫及的。难道你们不想要家了吗?不想要地球了吗?如果你还想要这些东西的话，那就请你们开始保护我们，开始保护你们身边的点点滴滴吧!”

现在大家也许有点后悔了吧!也许在想各种各样的方法来挽救这个世界，来挽救我们的家园吧!其实很简单，我们只需从身边的小事做起。看到有废纸掉在地上就弯腰将它捡起;看到小树苗倒了，就几个小伙伴合力，一起将它扶正，一起帮助它成长;保护野生动物，不再贪图它们那鲜美的肉，将它们残忍地剥皮吃肉;开一次小小的演讲会，呼吁人们保护环境，保护身边的人和物。一点一滴，从小事做起，从身边做起，为地球而努力。

让我们行动起来，保护环境，做好环保。不要让地球的环境再次受到破坏了!

保护环境作文二：

地球是我们人类的家园，也是人类的母亲。我们依赖它，探索它。这个蔚蓝色的星球多么美丽，但我们要知道：地球只有一个!

遗憾的是，许多人对于这个浅显易懂的道理却视而不见，继续为所欲为，妄顾地球家园的安危。环境科学家曲格平曾经说过这样一句话：“唯有变革，才能拯救人类的命运，也唯有变革，才能使我们的子孙后代世世代代生存下去。”里面的“变革”就是指环保。说得很对，所以如今有许多人拿着标语在街上喊空口号，却没有见过多的行动。难道这样污染就会好转吗?不!

看，我们城市里的河流的河水发黑发臭;排成长龙的汽车放出大量的废气;成片的绿地变成“石屎森林”;那清脆的鸟叫声消失得无影无踪。如果再这样下去，中国将继续贫乏水资源，空气将变得愈来愈浑浊，本世纪将有10%的鸟类物种消失。上述的事情，我们人类是罪魁祸首!

人人皆知：树木能吸收二氧化碳，排放氧气，净化空气，是我们人类生存的必要的条件。但是有一些人为了金钱去乱砍滥伐树木，造成了过度的水土流失，使大地的植被受到严重的破坏，绿洲和城市也荒漠化，我们人类的生存受到了威胁。就我们平时用的一次性筷子，每天都要耗费数十亩的森林，在那些人眼中，树木除了可以做家具和建筑材料外，似乎没有任何价值。难道还有人不懂树木对我们意味着什么吗我们居住面积已经很小了，如果再这样下去，可能连我们唯一的土地都失去。还有，我们的母亲河——黄河近年来河床和含沙量不断增高，成为全国污染最严重的几条江河之一。我们不能眼睁睁地看着黄河从我们手中枯竭，因而有许多环境学者纷纷研究治理黄河污染的方案，试图改善黄河的水质。但如果没有我们的共同参与，我们这个生命的摇篮——黄河将会走向衰竭和死亡。

如果我们再肆无忌惮地破坏环境，大自然将会给予我们惩罚。那些特大的洪水剥夺了不知多少人的性命，还有由于温室效应,南极北极的冰川融化导致水平面升高,海水淹没了沿海地区，经济损失惨重。难道这不是最好的证明吗

我的家乡广宁是靠竹海生态旅游来发展经济的，而今，某些竹林的环境恶乱不堪，让人叫苦不迭。竹海生态游是我们广宁发展的根，如果根被破坏了，怎能长出茂盛的枝叶、开出美丽的花儿呢

让我们善待人类、善待自然吧!不知大家是否看过《保护环境可做的100件事》这篇文章。其实，我们能做的事很多很多。如，在植树节栽一盆花、种一棵树;保护野生动物，是生态得到平衡;珍惜水资源，不要向江河倾倒垃圾;当环保小卫士，利用每个绿色纪念日宣传环保意识，让青山常在、绿水长流、泥土永芬芳……这都是我们力所能及的事情，我们为何不愿意实践呢?

现在，地球的生态环境加剧恶化，环保警世钟已经敲响了。让我们齐齐加入保护环境的行列，创立一个人与大自然和谐共处的美好未来，让人类与自然生生不息地繁衍下去吧。

保护环境作文三：

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。

金黄色，是一种幸运、光辉的颜色，曾是古代至高无上的皇家御用色。而此处的金黄色就没那么惹人喜爱了！这里黄沙满地，水源奇缺；岩石因风化而渐渐形成了独特的蘑菇状；还有迷幻无穷的海市蜃楼；只要你走进去，就像走进了永远出不来的黄色旋涡；随时随地发生的龙卷风和沙尘暴就像吃人的恶魔，如影随形。它，就是荒漠化的土地、地球的毒瘤——沙漠。

沙漠，就像潘多拉的魔盒，一旦不小心打开盖子后，就肆无忌惮地向四处抛洒着沙子，让自己的地盘日益壮大。它咆哮着绿地，吞并着水源，蹂躏着万物，且不停舒坦地伸展着肥硕的身躯，没有丝毫仁慈，一刻也不消停。它的孩子更加横行霸道，一会儿来个龙卷风，把所到之处的一切都吸进它的身体。龙卷风还可以一分为二，二分为四，它的分身术，真的很高深又迅捷；一会儿又来场沙尘暴，胆大妄为地将整片土地搅得天昏地暗、鸡犬不宁，时不时使出“佛山无影脚”。哎呀，虚虚实实的，还真会打“太极拳”，一切生物都被折磨地苦不堪言、痛不欲生。

难道我们就没有办法对付它了吗？答案是——有的！我们可以大规模引进沙漠植物，如金琥、沙棘、白杨等等，将它们植入沙地中，让它们用发达的根系牢牢锁住水土，改善土壤质量，减缓沙漠扩张，直至沙漠完全消失。

土壤是一切生物赖以生存的地方，是一切生命活动的源泉！我们人类必须停止乱砍滥伐，要珍爱绿地和土壤，多多植树造林；不能再将塑料制品或有害垃圾不经处理就置于土壤之下，请不要继续做沙漠的帮凶！

作为一名小学生，我们要从身边的小事做起，植一棵小树，种一束鲜花；减少使用一次性木制品；拒绝使用难以分解的塑料用品，真正地做一个环保小达人！

珍惜土壤，爱惜绿地，保护环境，拒绝土地沙漠化，这是我们每个公民应尽的义务！让沙漠走上不归之路，让绿色覆盖茫茫荒漠，这便是我们的终极目标！

珍爱地球，它是我们永远的家园，珍惜绿色，它是我们永远的守护神！

Our world is originally mountains, vast sea is blue, the vast sky is blue, the earth on which we live there are so many beautiful scenery, let us can not help but to admire the beauty of this world.

In this world there are ten million species of creatures, they get along, together in this live on the earth like a sapphire, tens of millions of years, too, will not change. But there is a kind of biological change the world, it is in this world with his proud technology to kill themselves, it is human. Human beings in this world only live for one million years, but it such as brute kills life on earth! In 2009, the Indian da-hong ruined homes of five million people in one hundred; In 2010, the Haitian earthquake left two hundred and thirty thousand people dead, according to estimates that by the year 2050, there will be two hundred and fifty million ecological refugees, we use our knowledge to kill themselves, as a human, I think its ironic.

The earth is in the vast universe, the only planet to harbor life, originally the earth is green hills and water, a piece is abundant, but todays earth after hurricanes, forest fires and drought in high temperature, is about to collapse, the earth began to shout for us, in the 2010 years, the earth has used its roar to kill two hundred and thirty-six thousand people, the earths voice we should hear, or the end of the world will come in advance.

Close to one end of the alarm, have "lungs of the earths forest gradually reduce, the earth began to collapse, there is only one earth, and this one belongs to you, rather than a human, the earth is our refuge, we should find a balance point and the earth coexistence, reduce the anger of the earth, let the human is no longer increase driver disaster, let us have a better living environment, but also for generations to leave some more living space.

我们的世界本来是青山绿水，汪洋的大海是湛蓝的，广阔的天空是蔚蓝的，我们居住的地球有太多美景，让我们不禁要赞叹这世界的美丽。

在这个世界上有千千万万种的生物，它们相处融洽，一起在这如蓝宝石般的地球上生存，过了几千万年也是一样，不会改变。但是有一种生物的出现改变了整个世界，它在这个世界用自己引以为傲的科技杀死自己，它就是人类。人类在这个世界上只生存了百万年，但是它却如猛兽般的杀死地球上的生物!在二零零九年时，印度百年大洪水毁了五百万人的家园;二零一零年，海地大地震让二十三万人死亡，根据估计，到了二零五零年，将会有二亿五千万名的生态难民，我们用我们的知识杀死自己，身为一个人类，我觉得很讽刺。

地球是在浩瀚宇宙之中，唯一能孕育生命的星球，本来的地球是青山绿水，一片盎然，但是现今的地球经过飓风、森林大火和高温干旱等严酷的考验，已经快要崩毁，地球开始对我们怒吼，在二零一零年时，地球已经用它的怒吼害死了二十三万六千人，地球的心声我们应该要听见，否则世界末日将提前来临。

末日的警钟一分一秒的接近，有“地球之肺”的森林逐渐的减少，地球开始崩毁，地球只有一个，而且这一个属于大家，而不是人类的，地球是我们的庇护所，我们应该找到一个和地球共存的平衡点，减少地球的怒气，让人类不再是加重灾难来临的推手，让我们有更好的生活环境，同时也替后代子孙多留一些生存空间。

环保局的局长：

我近日发现，我去上学的小路上有许多散发着恶臭味的垃圾。可是以前这条小路是没有垃圾的，是一条干干净净的小路，现在，小路上除了香蕉皮，就是零食的袋子，我心想：这么多的垃圾怎么没人清理？这里的居民怎么一点儿也不讲文明、不讲卫生？这样怎么能算是文明城市？我在心里怨恨着这些公民。

最近，有许多朋友在小路旁边的零食店买零食吃，并且将垃圾随地乱扔，有一天，我和朋友在这条小路经过的时候，朋友脚下踩了一个香蕉皮，“啊！”朋友一叫，重重地摔在地上，我心想，这里环境不好，还容易使人摔倒，环保局为什么不管呢？

我对环保局局长提出了建议：你这么做是不对的，如果有垃圾，要及时清理，如果不清理，就会使人摔倒，难道你们就这么不负责任？我希望你可以买一些垃圾桶，放到人多的地方，让他们有垃圾的时候可以往垃圾桶里扔。我还希望你分配一些工作人员到小区里做环保工作，让一些居民们更好地和我们一起保护环境。

最后，我希望天更蓝、地更美，让我过上幸福安康的日子。
