保护环境的英语高中作文【实用20篇】

陈*熙

我觉得要保护环境！因为近几年清得能看见底下沙子的小溪，通通变成了浑浊又发臭的下水道，这一切都是拜人类所赐。

此时，只要你打开电视，铺天盖地的新闻就会向你涌来，绝大多数都是关于污染的。海里的鱼吃到了由人类丢下去的塑料袋。那塑料袋会随着其他垃圾掉进胃里，使它无法进食，让它活活的被饿死，一位生物学家曾经做了一个实验，把一只死在海边的鱼开膛破肚，她在鱼的胃里发现了100多块垃圾，其中包括塑料袋、包装盒、纸片，这些死于非命的鱼终有一天会进你的胃。

再来说说大气吧！汽车的尾气不仅对人体有害，还对守护我们三十亿余年的大气层有害，大气层不仅给我们充足的氧气，来掌控着雨、雷、风等等。给我们带来了农田的肥沃，但人类的汽车已然对它造成了极大的伤害，使它常常“发火”、“发怒”、“哭泣”，有些地方一年也下不了一场雨，有些地方却雨水成灾。尾气还会造成氧气里含有有害物质，PM2。5，一个极小的怪物，它不仅小于2。5毫米，还会对人体造成极大的伤害。

我们应该减少尾气排放，多坐公交车和多踩自行车，如果大家都保护环境，那地球母亲就不会累了！

我们都需要爱护大自然，因为人类与大自然是分不开的。

梁*烯

地球，我们的家。以前鸟语花香，绿树成荫，小溪清澈见底，如今，雾霾之天，海面上升，我们的祖先会怎么样想呢？

为了保护环境，我们要做到垃圾分类。我们把垃圾分为四种：可回收、有害、其他、厨余垃圾。这样就能够把垃圾的用处发挥到最大效益了。

可回收垃圾，可以回收利用它们。就拿我们学生最讨厌的试卷来说，把试卷放到机器，就可以重新造出两倍的试卷！

而厨余垃圾，可以做成肥料和洗洁精，这些腐烂的果皮，就可以变废为宝了，这真令人感到震惊。

你如果想一错再错，用自然换来科技的生活，那是十分恐怖的。工厂发出的烟气、焚烧垃圾，会有可怕的小杀手——PM2。5，它虽然小，可是能够把你的生命逼到绝境！人类的过度砍伐，使得全球没过三分钟就会有一百种珍稀动物灭绝，这多么可怕啊！

而在遥远的北极，因为温室效应，北极熊变得越来越瘦，不仅脱毛，食物也没了，只好翻人类垃圾箱过日子，还有可能食物中毒。

现在我们还可以大吃大喝，但请为我们的下一代“留一口”。

同学们：

你们知道吗？近年来，我们的城市变得越来越脏，环境变得越来越差。为什么？我们人类，就是罪魁祸首。

你们也许会慢慢发现，大街小巷到处是垃圾，大海里都是工厂排放的污水，一望无际的天空将不再蔚蓝……

随着世界经济的发展，人口不断增多，城市建设规模也日渐增大，可是人们还是没有环保意识。要知道，海滩上、街道上、公园里等，可是能经常见到垃圾那“可怕”的身影。

在这里，我们向全校同学发出保护环境的倡议，让我们从今天起努力做到以下几点：

1、要有环保意识，只有意识到“保护环境光荣，破坏环境可耻”，才能时刻注意环保，从身边的小事做起。

2、严禁随地吐痰，乱丢垃圾，踩踏草坪。

3、人人争做“环保小卫士”，养成良好的行为习惯。

4、提倡不乱扔垃圾，应该把垃圾分类扔到垃圾箱中。

一份倡议，一个承诺，一种责任。亲爱的同学们，让我们一起行动起来吧！

蔚蓝的天空；清澈的小溪；一碧千里的草原以及郁郁葱葱的森林，这一切都源自于我们的地球母亲，她是多么的美丽，又是多么的无私啊！我们作为这个生机勃勃的世界里的居民，更加应当爱护这多彩的环境，不让它被破坏。

一天，风和日丽，阳光明媚，在这舒适的好天气中，我迈着轻快的步伐，背着书包往家走，正当我过完马路时，前面的一个叔叔将喝完的可乐瓶随手扔在了地上，悠然而去，而紧接着，原本在我身后的一位环卫工奶奶迈着缓慢的步伐，却毫不迟疑地走向可乐瓶，有些吃力地弯下腰，将它捡起。看到这一幕的我先是一惊，随后便发出了质疑：捡起一个垃圾，在我们看来似乎是一件微不足道的小事，但对于一些年迈的环卫工人们是多么的吃力啊，更何况在离垃圾箱只有几步远的情况下，我们为什么不能将垃圾丢入垃圾箱呢？这不需要花费多少时间和精力啊，为何要让这些老爷爷老奶奶们如此费心呢？

想着想着，我回到了家中，将这件事告诉了妈妈，想不到，妈妈竟也愤愤地感慨起来：“小雨，那个叔叔这样做是不对的，但你可不能这样做哦，我们要做一个文明的人。”是啊，城市是我家，爱护靠大家嘛，从今以后，我下定决心，要做一个好公民：文明用语嘴边挂，见到垃圾捡起来，以后不会浪费水，绿色出行要做到！每人节约一滴水，汇集起来将是一片海洋；每人多种一棵树，以后将是一片大大的森林；每人捡起一个垃圾，我们的生活环境将会更美丽！

保护城市环境，人人有责！

今天放学以后，我训练完了，开开心心的准备回家了。我从书包里掏出自行回家卡，双手递给保安看。出了校门，看见一个高个儿，戴眼镜的姐姐，脸上有一些小小的雀斑。额头上长了一些红色的点点，不知那是什么东西。最引人住瞩目的就是她手中抱得那一沓厚厚的宣传单。

我其实是不想拿传单的，因为我根本就是不需要呀，我故意绕开她，但是，那个大姐姐飞速的跑过来，我本来想说：“姐姐，我不需要，不要给我。”但是我还没有张口说，那个姐姐就把传单塞到了我的手上。哎！我想了想，给了就给了吧，到时候回去给爸爸妈妈看一下就好了，不要的话就扔进垃圾桶吧。

走在回去的路上，我正好看见一个大约上三年级的小朋友，他走到他家的小汽车旁边，他的妈妈把车门打开，小朋友上了车，随手拉好车门，上了车，你知道他妈妈做了什么吗？她他妈妈看到他车头的后视镜上夹了张传单，就随手把传单一扔，扔到了旁边的草地上。

这是那位妈妈的举动让我很生气，本想对她说：“保护城市环境，人人有责！你真不为你自己的行为感到羞耻吗，发传单的人是不应该随便把传单夹在你车上，但是你也不能随便扔啊，如果你不需要的话，找一个垃圾桶扔了也好啊，或是回到家，扔在自己家的垃圾桶里啊。如果中山的每一个人都像你这样，那清洁工阿姨和叔叔得多么辛苦，得多几次弯腰啊！你也不为她们想想，假设这个世界上没有清洁工，那中山不就成了垃圾场啦。你以为这是小事一桩，是不足挂齿的，但你这一份小事，积少成多，就成了大事啦！俗话说的好：“勿以善小而不为，勿以恶小而为之。”你觉得你那样做对吗？你想想看，你也是做妈妈的，为什么就不能给小孩做一个好榜样呢？难道保护环境真的很难吗？”可惜的是，我还没有走上去，她就马上开车走人了。

同时，我也很想跟那个同学说：“我们学校的校长说了多少次这种事，难道你就没有听到过。你作为轩小的学生，就算校长讲的你真的没有听到，但你也要有自知之明啊，那条路紧挨着我们的学校，也是我们学校的一部分，你要保护校园环境啊！虽然扔垃圾的不是你，但他是你的亲人，是你的妈妈呀，我知道你看到了你妈妈错误的举动，但是你没有制止你的妈妈，这就是你犯得错误。人人都会犯错误，没有人是从来不犯错误的，就如你亲爱的妈妈，你为什么不批评妈妈随地扔垃圾呢？你比如说我们班的张之韵同学，我看过他学的一篇文章，题目叫《批评妈妈》，人家女生都敢批评妈妈，你是个男生，胆量也不比张之韵小啊！我衷心地希望以后你可以勇敢的批评妈妈，让你的亲人明白我们不应该乱扔垃圾，为了保护城市环境，保护校园环境，为了清洁工阿姨不再那么辛苦，为了你所有的文明，做到吧！”

在回家的路上，我看到了很多的传单，我是数也数不清楚，马路上，大树下，草坪，街道，到处都是传单。我很想问问那些乱扔垃圾的同学和家长，你们为什么要这样做。我叹了一口气，然后从地上捡了几张传单，扔进了垃圾桶。

我想向生活在中山的人们建议：“让我们共同保护我们城市的环境吧，不要再乱扔垃圾了，爱护我们的家园吧！”

四年级 曹荣洲

今天下午，我和妈妈去广场，我们看到满地的垃圾，有塑料瓶、塑料袋和一些零食袋子，这个时候我想起了老师给我们布置的作业，就是拍一些破坏环境的一些照片。

所以我们就把这些拍了几张。我们又看到有人把抽的烟，火还没有灭，就扔在小草上面。我们把这些拍下来，又把烟踩灭之后劝告那个人：抽完烟以后要灭掉扔进垃圾桶里。

然后，我们回家了。又在四小旁边看到有人在烧东西，破坏空气。所以也拍了下来。

我们回了家从这三张里选一张，我就选了在四小旁边烧东西的照片，发给了老师。

我们要是不保护环境，地球爷爷就会很难受。

地球，是每一个人的母亲；地球，是人类的栖息之所；地球，是每个生命的摇篮。和蔼可亲的地球，在今天，就像生命垂危的老人，即将奄奄一息…

“哗—哗…”一声急促的流水声从我耳边响起，用水人不知踪影。现在科技越来越发达，马路上有种类繁多的汽车，但是，人们却不知，汽车的废气里主要是“二氧化碳”，“二氧化碳”对我们的身体健康有很大的影响，会使我们生病。树木的滥砍滥伐，做成一次性筷子，一次性纸杯等等，就会让我们的大自然变成荒漠。工厂里排出的废水里有可能含有毒化学物质，以及重金属超标，我们一不小心喝到这样的水，就有可能得不治之症，让世界少去一个生命而惋惜。

我建议：在有水的地方贴上一则标语，提醒人们：“节约用水，别让最后一滴水变成人类后悔的眼泪。”污水的排放，要通过污水处理达标。在室外，尽量不要开车，减少尾气排放。我们要尽量保护每一棵树木、每一寸花草，多植树造林，可以预防沙尘暴、洪水、泥石流、酸雨等灾难，还可以吸收二氧化碳，净化空气。

让我们行动起来，保护环境，从大家做起，从身边做起，从自己做起。保护环境，人人有责！不要让地球的环境再次受到破坏了！

My Views on Environmetal Protection

Nowadays, the world we live in is becoming more and more intolerable because of environmental destruction. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. Recently,haze weather has become a usual phenomenon here in large part of China. People are forced to wear the mask to avoid breathing poisonous air. Some people think it is impossible to solve the problem,however,from my opinion,if we find out the reason and take effective measures the environment can be better.

If we trace the cause for haze weather,the main points are as follows,first,our countrys air quality standards are rather lax and evaluation factors are limited,so you will see that current air appraisal system has defects. Second,some people just go for economic interests instead of turning out products according to relevant law and regulations. They tend to use obsolete equipment in which they are more likely to emit a great deal of wasted air. Third,across our society,the awareness of protecting the environment has not built up so that people havent formed a habit of using green product and saving energy as much as possible. If we dont take action to show respect to the environment, we will have to face an increasingly awful situation.

Therefore, effective measures should be taken and laws passed to conserve the environment. In my opinion, to protect the environment, the government must take even more concrete measures. First, people should be educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. Second, much more efforts should be made to put the policy of population into practice, because more people mean more pollution. Finally,laws concerning environmental protection should be put into effect and enforce strictly just as our government has been doing. To sum up,if we work together to take out such measures,our environment will get better and better and haze weather will vanish completely.

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。

[保护环境的英语小作文

From June1, 2008, shops and supermarkets are forbidden from offering free plastic bags to customers, according to a new law. A nation-wide campaign against plastic bags has been launched.

Nowadays, Chinese people use up to three billion plastic bags a day. While being very convenient to shoppers, plastic bags also cause serious white pollution” and waste resources.

Though the ban may cause some inconvenience to shoppers, it can help reduce the use of plastic bags when people have to pay for them. Besides, the ban, in away, can promote public awareness of environmental protection.

So I think it necessary to forbid shops and supermarkets from offering free plastic bags. When shopping, we can use cloth bags or baskets instead of plastic bags as we used to.

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！

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. 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. Pollution is, in fact, threatening our existence.

The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.

全世界的环境问题变得越来越严重。例如汽车污染的空气影响了人们的呼吸，工厂释放污染的气体，山上的树木被砍伐，污水不断被排人河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。事实上，污染正威胁我们的生存。

地球是我们的家园，我们有责任为我们自己和我们的后代去照顾好它。庆幸的是，愈来愈多的人们已经意识到这些问题。政府已经采取了很多措施去解决这些问题，法律已被通过以制止污染。我希望这些问题在不远的将来能得到解决，我们的家园变得越来越好。

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 mans 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.

全世界的环境问题在变得越来越严重。随着工农业的发展，汽车制造噪音、排放毒气，山上的树木被砍伐，污水不断被排入河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。整个地球生态平衡正在改变，环境的巨大破坏已带来负面影响，甚至对人类生存带来巨大威胁。

我们必须面对现实，采取行动解决环境问题。例如必须通过新的法律严格控制工业污染问题，大众必须接受污染危害的教育等。我们希望这些措施的有效实施能带给我们一个健康的环境。

国家在富强，时代在变迁，社会在发展，人们的梦想也随之变化，从之前渴望的丰衣足食，到现在的汽车、楼房，生活变的越来越好、越来越红火。

但是我们居住的环境就发生了很大的变化，河水没有之前清澈了，天空没有之前蓝了，环境污染特别严重。环境越来越差，到处可见垃圾袋，更有人把小区里的绿化毁了，种上了蔬菜。这些还不是最严重的，更严重的是春天槐花开了，有的人为了一己私欲用钩子把槐花给拉了下来，不一会数上就光秃秃的。没有一点春意的感觉。让人看了心疼。不仅如此，秋天桂花开了，人们照样去采摘桂花，摘桂花不让他们有一点难过，这种事情兴许你也做过，也看到过，但是你们制止过这样的行为吗？

我的梦就是保护环境，保护本土植物，让植物品种不在单一，病虫灾害变少。拒绝滥砍滥伐要从小做起，在小区的荒地上种一些花草树木，不仅可以绿化环境，还可以防沙固土，何乐而不为呢？不仅自己要做，还要向同学们宣传植树造林的好处，让同学们也参加到植树造林的环境中走来。还可以向老师们提议在校园的一些荒地上，种植一些树木。让校园变的更加生机盎然，充满生机。眼睛多看一些绿色，也是有好处的，可以使眼睛放松，有利于我们的视力提高呢。保护环境，人人有责，让我们一起行动吧，植树造林，刻不容缓。

我们即使不参加活动，也不能乱扔垃圾。看见垃圾要捡起。做一个好学生。减少水土流失，打造一个鸟语花香，环境优美，令人向往的中国吧。

保护环境就是我的梦，也是全国十三亿中国人共同的梦，让我们一起创造祖国美好明天吧，让我们一起为梦想奋斗吧，为自己加油吧！

As it is known to us, Ping An was chosen to perform on the CCTV Spring

Festival Gala with his melodious and strong voice. Also, he had a great

achievement on this dream stage. Although he hadnt gain the popularity among

the audience at the beginning, he always kept his dream in mind and never gave

it up. It is his success that brings home to me the power of dream.

A life without a dream is a life without a sun. Therefore, in no

circumstances can we give up our dream. Unquestionably, dreams are of great

importance. For one thing, a person having a dream will be considered to be more

responsible and unswerving. For another, in pursuit of our dream, there is a

chance that good habits and positive attitudes can be formed, contributing to

our success.

As for our students, what we should do is to choose a healthy seed and

plant it on fertilized soil. Firstly, knowledge is the foundation of dream

realization, so we should spend much time in study to enrich ourselves.

Secondly, it also takes perseverance and confidence if we want to realize our

dreams. Last but not least, we should not be craven and timorous but brave when

we meeting obstacles.

With the development of Internet, more and more people tend to shop on the

Internet. Online shopping has provided some benefits for us, but it also has

some disadvantages at the same time.

For one thing, online shopping has brought some convenience for consumers.

Instead of going one shop to another, people can choose and buy all kinds of

commodities they like as long as they click the mouse gently. This is not only a

better choice for the old who do not have enough energy to go outside but also a

great convenience for those who have no time to go shopping in person. In

addition, consumers have more choices and can do some comparison when they are

shopping on the Internet. They can glance over various commodities in all

shapes, sizes and colors and decided to buy or not. Furthermore, online shopping

has made a great contribution to the development of express delivery

industry.

However, for another, shopping on the Internet also has some shortcomings.

Firstly, those who shop on the Internet can’t try the goods before they buy.

Sometimes, the real goods are not the same as the goods they see on the

Internet. Secondly, some shops on the Internet are dishonest and they would not

deliver the goods after paying. And if this situation happens, the consumers

would find nowhere to complain and never pull out the money any longer.

Therefore, we should pay more attention when shopping on the Internet.

As is known to all, waste on campus has become a more and more serious problem. We can easily see many students dump a lot of food in the garbage can. Some students spend thousands of yuan buying fashionable clothes and so on.

The negative effects of waste can be shown in the following aspects. In the first place, it makes some students dependent on their parents for money, which is harmful to their development.

If they don’t learn to support themselves, they will be “useless people” when they graduate. In the second place, it is not easy for our parents to arrange for our schooling. Last but not the least important, there is no denying the fact that our country is still poor. There are many people who cannot go to university and many poor people still need our help.

As far as I am concerned, I should set a good example to reduce waste on campus. First of all, I will refrain from wasting anything, from food to stationery. What’s more, I’m determined to call on more schoolmates to fight against waste. Only through these measures can we hope to reduce waste on campus.

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. "Mercury said," Sister, see you now so beautiful, I am a little jealous. "Earth said:" Thank you all for my sacrifice so much, I am now healthy, or Thank you all, thank you, "said the sun," the stars, after this action, humans have recognized the importance of the earth, and I declare that the rescue of the earth is a success.

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.

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。

如果你想保护空气，就要一点小事做起，减少汽车排气量、烟囱减少排烟量，就可以让空气清新一些。

如果你想保护卫生，也要从一点小事做起，例如看到香蕉皮或其它垃圾，要主动扔到垃圾桶里，还可以带动班上的同学一起来进行一次环保活动。到更多地方收集垃圾并扔掉。减少垃圾排放量。

如果你想保护小草，就可以树立一块牌子，上面写：“小草是我们的朋友，请保护它们。防止更多的人踩踏草坪。

你还可以做更多的事情来保护环境，比如说把垃圾分类，能更清楚的分清它们。少用一次性筷子，可以保护更多的树，减少沙尘暴的侵袭。总之要记住，地球只有一个，我们要好好保护它。

Protect our environment

In the last several decades, our earth has been extremely polluted, such as air pollution, water pollution, noise pollution and so on. In recent years, the extreme weather becomes more and more frequent. Winter gets colder and summer becomes hotter and it rains more frequently. All of these warn us that protecting the environment is a serious and emergent event. As our general people, we should build proper lifestyle. We should pay attention to water and light saving. When we go out, we should firstly choose the public transportation. The most important is that we must realize that we can do a lot of things to protect our environment. Its our duty to make our home better. Let’s change from ourselves.

我发现现在有好多人都在乱扔垃圾，给地球造成了很大的环境污染。每当我看到满地的垃圾，我就十分生气。

乱扔垃圾对环境会造成很大的影响。最常见的空气影响是雾霾。现在的雾霾程度基本是中度。有时的重度雾霾在三米以外就看不到行人了。垃圾不仅造成空气污染，还会破坏海底生物。其中，海龟就是“受害者”之一：当旧渔网沉入海底时，会把海龟缠住；当塑料袋沉入海底时，海龟会把它错当成小鱼吃掉，导致窒息死亡。

垃圾，别看它普通，它对生物的危害非常大。它会破坏生物链，严重的会使物种灭绝，使一些物种消无声息地死亡。

“地球是我家，环境靠大家”。让我们从每一件小事做起，保护环境，使我们的地球更美吧！

岁岁月月，朝朝暮暮;年复一年，日复一日。时光一去不复返，而地球的危机只要我们的人类不断地去努力是可以解除的。但是有许许多多的人都不知道地球的危机有那一些，如水资源的紧缺、大气资源的缺乏等等等。其实这些危机都是人为的!如：水污染危机、大气危机、森林危机、矿藏资源危机……因此，我们一定要用心去保护地球，去珍惜资源。; year after year, day after day.Time is gone, and the crisis of the earth can be lifted as long as our human beings continue to work hard.However, many people do not know the crisis of the earth, such as the shortage of water resources, the lack of atmospheric resources, and so on.In fact, these crises are artificial! For example: water pollution crisis, atmospheric crisis, forest crisis, mineral resource crisis ... Therefore, we must protect the earth with our hearts and cherish resources.

接下来让我先给你们说一说水污染危机吧!20__年1月，广西好江河水资源突发严重镉污染，该事件水中的镉含量约20吨，污染波及河段达300公里，引发当地居民饮用水安全的危机。20__年__月，云南曲靖陆良化工实业有限公司5222.38吨工业废料铬渣非法倾倒导致污染，倾倒地附近农村77头牲畜死亡。水是生命之源，万物之本。没有水我们的生命就无法生存，万物就无法生长。所以，我们一定要保护水资源，让地球上的水更清。

下面我再给你们说一说矿藏资源的危机吧。2003年对于中国的矿业企业来说，是不堪回首的一年。电荒、煤荒、油荒……从来没有像现在这样让每一个中国人感到痛彻心骨。而更多不可再生资源的全面告急，更让那些与其密切相关的人们坐立不安。去年12月，一份送往国务院的名为《矿产资源与中国经济发展》(社会版)的报告，在社会各界引起强大反响。

“该报告推翻了以往各机构关于中国近30年对石油、天然气、铁、铜等主要矿产的供需缺口预测，第一次以触目惊心的数据，彻底颠覆了‘中国地大物博’的理念。”报告以大量的事实证明，“除煤之外，我国主要的矿产资源都已告急”——中国油气资源的现有储量将不足10年消费，最终可采储量勉强可维持30年消费;到20__年，中国石油的进口量将超过5亿吨，天然气将超过1000亿立方米，两者的对外依存度分别将达70%和50%。人们啊醒醒吧!当你看到这些触目惊心的数据后，你又有何感想呢?如果你是一个有头脑的人，就一定会知道保护环境已迫在眉睫，珍惜资源要从我做起，从今天做起，从身边的小事做起。只要我们人人认真学习环保知识，努力做到珍稀资源保护地球，那么我坚信我们的地球明天一定会更美。

人们啊醒醒吧!如果再不保护地球，我们将无法生存!为了我们人类的美好生活请珍惜资源保护地球吧!
