保护环境英语作文80词高中【通用20篇】

Music is the important part of my life. The world needs music to amuse

peoples life. As they live in the fast pace, music can bring them the great joy

and relax. Since I was very small, I fell in love with music and every time when

I heard music, my body would move and feel relaxed. The function of music is

various.

There is a famous song, which called let the music heal your soul. A lot of

young people have their favorite singers. When they see their idols face to

face, they would say thank you to the singers, because their songs inspire these

young people to move on in the dark days. The songs deliver positive messages to

the public and inspire them to never give up.

Listening to the music is the main way for the young people to release

their pressure. Every day before I sleep, I will listen to the light music,

which helps me to take relax and make me sleep well. The reason why so many

people like to KTV after their work lies in releasing pressure. They need to

shout and then forget about the annoyance.

Music is favored by everyone and it is the indispensable part of our

life.

听，风在喘息；看，水在抽泣。你是否感觉到，祖国的生命气息逐渐减弱，它在呼喊：请保护我们的环境！

时光就像夜空匆忙滑过的流星、像瞬间绽放的火花，记忆中小小的故事静止了，像枫叶一片片飘落。我们的母亲在经过几个世纪的消磨下变得更加强大，但心灵的伤口也随即越变越大。

她精心哺育着每一个生灵，但她付出后得到的回报又是怎样的呢？

环顾四周，我们的处境真是不堪入目：各式各样的污染侵蚀着我们的家庭、吞噬着我们的健康、威胁着我们的未来。在世界尽头的某个城填，那里本是奇山峻岭、古树浓荫、奇花异鸟、鱼米飘香，人们世代和睦相处。但是现在，科技的进步促使人们有了不同的表现：随地吐痰、狠命抽烟、排放废气、乱砍滥伐、践踏花草……优美的环境禁不起这样的折磨，最终倒下了，病怏怏地存活着。

环境一旦受到污染，就很难治愈。当有一天，到了已经无法挽回的地步，如果才想起保护，那么一切都已经迟了。那时，植物枯死，从此再也没有了绿色，剩下的只有灰暗；天空没有了蓝色，我们呼吸不到清洁的空气，甚至也看不到光明；最后，人类就会面临死亡，国家也会走向毁灭。

保护环境是一份事业，更是一份责任，每个人都要从自身做起，只有大家都参与到环境保护这份事业中来，世界才会变得美好。同时，我想对那些破坏环境的人说：“你们与其眼睁睁地看着资源流失、环境污染，也不愿伸出手去保护我们的环境吗？觉醒吧，那是我们的生存之本，不要为了眼前的利益而蒙蔽了自己的双眼！”

我不愿再次听到祖国的哭泣，治愈祖国的创伤是我们义不容辞的责任。让我们一起携手，大声呼吁：保护环境，人人有责！

here are many kinds of animals in the world,but not only the humans.we live in the same world,and we should be friends.as everybody knows,the humans are the rulers of the world today,so we should protect our friends--the animals!

But how to protect them?as first,i think we must stop killing the rare birds and animals,especially the young ones.the second,we have to protect the environment,to make the sky blue,to make the grass green,to give the animals a comfortable space to live

星期六，老师叫我们去调查环境，我就和我的小伙伴一起来到了洹河。

听说，以前的洹河水清澈见底，还很静，静得都把周围的景物照映在河面上，像一面大大的镜子。这条小河里的鱼非常多，成群结队，各种各样，颜色各异；有红的鱼、白的鱼、金的鱼、黑的鱼……河面上的鸭子多得数不清，都成千上万了，像绣在绿色锦缎上的一朵朵白色的小花。周围的花千姿百态，万紫千红，芬芳迷人。柳树的枝条像一块块碧玉。草像一个个小孩，从地下探出头来，人们都非常喜欢这条洹河。

可十年后的今天，洹河水变成了棕红色，泡沫也成了棕红色的了，还有的地方，河水是“绿色的”，还很混浊，还有的地方水是蓝色的，那里垃圾非常的多，鱼虾也都搬家了，鸭子也飞走了。周围的草都死了，土地上也是垃圾，散发出了刺鼻的气味，引来了许多苍蝇。

这都是人们不重视环境，政府开始现在整治环境了，到处都挂着“禁止燃放烟花爆炸”的条幅，禁止有害气体排放，汽车限行，希望环境得到改善。

为了花更红，为了草更绿，为了空气更清新，让我们行动起来，保护环境，保护我们共同生活的家园。

我是一条美丽的小鱼，我的眼睛水汪汪的，身上有着整齐的鱼鳞。我生活在一条清澈见底的小溪里，周围是连绵起伏的大山，一早，阳光闪耀，洒在我身上，我全身闪着金光，小溪也变成了一条闪着金光的溪。我们家世世代代都生活在这美丽的小溪里，过着自由自在的生活。

每天我醒来，就会和我的朋友们一起玩耍。刚出生不久的小鱼苗成群结队，用力地甩着尾巴，瞪着圆圆的眼睛，从我身边游过。最有趣的是小虾，他弯着腰，把身子缩起来，使劲一蹬，就像箭一样地从这边游到了那边。最懒的是小螃蟹，老是躲在石头底下，好不容易露出来头来，可吹了个小跑炮又缩了回去。晚上，我偶尔跃出水面，欣赏美丽的星空，天上有一条银河，小溪也变成了银河。

可是，好景不长。有一天，人们在小河边建起了工厂，黑色的、红色的、发臭的……液体，不断流进小溪，见多识广的乌龟爷爷说：“不好，不仅是那些臭水，人们把生活垃圾也扔了进来，五颜六色的塑料袋、用过的餐巾纸、泡沫……”好奇心最强的小螃蟹钻进塑料袋里，可再也出不来了，小鱼吃了一块泡沫，可第二天就白肚皮向上，再也没有动过。一天天过去，越来越多的小伙伴象他们样，小溪里没有了笑声，溪水不再清澈见底，我们只能无奈地离开家乡，人类，我恨你们！

水是生命之源，请你们住手，让小溪重回清澈见底，难道你们没看到吗？清澈见底的小溪没了，清洁的小河没了，小虾、小螃蟹、小鱼……也没了！我们都只有一个家——地球，所以请你们保护好我们共同的家园。

In our life, everyone 情态动词+have . Some could be found at last. But some of them couldn’t be found forever. I had an unforgettable experience. One day, I went home happily.

地球是我们赖以生存的家园，它为我们提供一切生存必要的条件。我们也是地球的主人，要担当其责任去保护它。因为地球只有一个！

随着社会的不断进步，科技的不断发展，然而有的人们的道德却出现了偏差。笔直冲天的大烟囱，雄赳赳的冒着滚滚浓烟；工厂直接把污水排放到河流；马路上，一辆接一辆的小汽车，冒着烟疾驰在马路上；森林被为了一己私欲的人们而滥砍滥伐，造成森林资源大面积的减少；到处是随处丢弃的垃圾……空气被污染了，伤害着人们的身体；河流被污染了，鱼儿死了，我们的生活用水越来越肮脏；森林消失了，自然灾害接踵而至……地球妈妈留下了伤心的眼泪，警钟早已敲响。

为了人类更好的生存，为了生活更加美好，让我们从现在做起，从小事做起，保护我们的地球，增强环保意识，倡导低碳生活。我们要节约用水、电、煤气，不使用一次性物品，不乱扔垃圾，出行少开车，宣传环保知识……

山川秀美是我们共同的追求和理想！保护环境，人人有责！【公众号：宋奕萱】

如果没有了树木，天空将会阴沉沉的，各种疾病会在人类之间传播。正如病毒们所说的：“假如没有了树木该多好呀，但现在树木已经不在了，真是天助我也啊!”人与病毒之间的战争就爆发了。

首先是蒙古，那里生长着一种病毒，有点像枯手。大多数会破坏草、树、花……但如果幸运的话，这些病毒会使草、树、花……长得更好。假如你是动物的话，而且爱吃草，说不定哪天你是因为草而死的。

再说一下成都吧，我们这走几步就是垃圾，而垃圾桶里却一个垃圾也没有，望着那被人遗忘的垃圾桶，我不禁想起了身边的清洁工阿姨还有叔叔。最重要的是听老师说：“好像成都要干旱，那一场雨就是人工降的。今年都是人类惹得祸”有人会问：“雨下了应该有彩虹的呀?”我想告诉你：“是因为空气不清新，灰尘又很多，能见度太低了，所以成都没有彩虹。”但如果成都有沙尘暴，成都就不叫成都了，应该叫沙城才对。

如果你对生活很满意，但你忽略了一点，就是大家。

如果人类的科技很发达，但是植物却很少。

还好这只是如果。

The picture shows the pollution caused by chimneys of the factories in cities. Often, the sky is covered by large clouds of smoke from chimneys. The air is nearly suffocating, especially in the evening as it becomes cold and the smoke is spreading everywhere. The scene reminds us of the end of the world.

From the picture we can infer that the drawer of the picture intends to convey to the readers that unplanned factories has brought about great hazards to the city air condition. Due to planning mistakes, factories were usually placed in the center of cities, among residential and business districts. Besides, nearly every block has several chimneys for the heating system, which makes the whole city immersed in thick columns of smoke. As a result, respiratory diseases have been reported to be rising and old people dying of the worsening air pollution.

Pollution is really a hot issue in the world. If we don’t take useful measures, we may live in terrible surroundings, and some unexpected results may come out in the end. So, what we should do is to bring down the problems caused by chimneys. For one thing, factories with chimneys should be moved out of the center of the city and it should be made sure that the waste gases are at least not poisonous. For another, other means of heating should be developed to stop using coal. In a word, in the city there should be no coal, no chimney, and no smoke to pollute the air.

有一天，小花和弟弟讲，在上学的路上看见垃圾桶，有很多很多垃圾。小花说：“大概是，小朋友把垃圾当足球踢了，结果没有踢到垃圾桶里，垃圾撒的满地都是。小花，告诉弟弟，你来写一句话，也就是说，告诉人们要保护环境，不可以乱丢垃圾。就这样，我来把这些垃圾放入垃圾桶，好不好。

小明说，好的。过了一会儿，姐姐把垃圾都，清理干净了。小明也写好了，小明又说，姐姐，你来看看我写的好不好？姐姐说很好。

小花和小明长大了，他们又经过了那个垃圾桶，看见他都激动旁边，没有垃圾了，小明，写的，纸条，也没有被撕掉，而是完完整整的叠好了，小明又说人们已经知道要保护环境了，小花说，是啊，再过几年，我们的生活会更加美好的。

We need to follow all kinds of public rules, such as the manner rules and

the traffic regulation. If we break the rules, then all the work will be out of

order and everybody will suffer the loss. But few people just ignore the rules

and waste other people’s time and money.

Chinese high speed train has won many praise from foreign people. The

trains always start off as the timetable and reach the destination on time. High

speed train is popular by the public by its speed and punctuality, but what if

someone breaks the traffic rule? Recently, a video got popular on the Internet.

A woman was stuck in the door of high speed train and the staffs tried to stop

her but failed. She said her husband was on the way and she wanted the train to

start off later. How ridiculous it was. How could she let all the passengers to

wait for her. Everybody’s time is precious.

Though the woman apologized after the policemen’s education, what she did

discomforts the public. The way she acted wasted the public’s time. It is our

duty to follow rules and keep the public in order.

很多人认为“环境保护，是社会和大人做的事情，我们还小。就是做的什么也体现不了我的作用?”其实我们生活中的许多习惯与环境保护息息相关、密不可分。 Many people think that "environmental protection is what society and adults do, we are still young. Just do what we do not reflect my role?" In fact, in our lives, in our livesMany habits are closely related to environmental protection.

在我们学校许多同学都习惯使用一次性的墨囊，它轻巧，方便携带，不已漏墨，但你知道吗?每位同学每学期使用大约20个墨囊，一个四十人的班级就是800个，一个年级大约9000个，一个小学四个年级(一、二年级不用)就是36000个，想一想，一年是72000个墨囊，一起放在学校的广场上，估计也是厚厚的一层吧!要生产这么多的墨囊需要多少吨塑料和消耗掉多少吨的煤炭呢?估计也是个不小的数字。如果我们使用瓶装的墨水，可以既节省费用同时又保护环境，为什么何乐而不为呢?

当风吹起的时候，漫天的垃圾袋随风起舞，有时还会挡住你的视线，造成事故。如果每人每天少用2个塑料袋，全国一天就是27亿个，一年就是9855亿个，这个数字太恐怖了。其实每个人少2个是很容易做的事，再加上生产这些袋子背后的消耗，我们能为环保事业做的贡献不小吧!

再来看看不爱护环境的后果吧!由于工业生产造成下降酸雨的比率大大提高，而大量的酸雨会“吃掉”大自然的绿色的美景，树木花草的大量死亡，土地的裸露。今年全国的雾霾天气，他也有不少的功劳，而带给人类是让更多的人患上呼吸道疾病，甚至造成死亡。

所以说，环保就在我们身边，只要你一点的改变，就能改变的整个地球的环境;你离环保并不遥远，你的举手之劳，或许就能还世界一片洁净。让我们行动起来，从改变自己开始，让我们的家园——地球变得更加洁净、更加和谐!

别样的秋天

秋天，一个美丽而又丰收的季节。稻子熟了，黄灿灿的，似乎对人们的辛勤耕耘很满足，开心得笑弯了腰。但是，一切美好的背后总是不尽人意地藏着“隐形杀手”。

想起往年，每到这秋收的季节，天空中总是浓雾弥漫，伴随着刺鼻的烟味，焚烧的秸秆红红火火映透半边天。我曾问过邻家的伯伯：“为什么要焚烧秸秆呢?你看，这烟雾弥漫的，不是污染了空气吗?”伯伯一肚子苦水：“我们也没办法呀，现在条件好了，家家户户都有煤气灶、电饭锅，秸秆运回去也派不上用场。再说有的人家已经拆迁，住进了小区，运回去也没处放呀!”看着伯伯无奈的表情，我不知该怎么劝了。是的，农民有自己的难处，可是焚烧秸秆产生的浓烟含有大量的二氧化碳和烟尘，不仅危害人们的身体健康，容易引发火灾和交通事故，还会破坏土壤结构，造成耕地质量下降，真是祸患无穷啊!

握着放学前老师发给我们的《抵制秸秆焚烧，共创文明家园》这封信，我着急起来：我能为环保做什么?深吸一口气，蓦然发现，空气中没有呛人的烟味，倒是呼吸到桂花以外的秸秆的清香，怎么回事?看看空旷的稻田，几台大型机器正在紧张地吞吐，那一只只“小铁牛”依次向前把摊在地上的秸秆吃到肚里，几秒钟后尾部就吐出了捆得结结实实的秸秆包，真神奇。一打听才知道，这些小铁牛是先进的“打包机”，港区政府为了解决群众的后顾之忧，联系了一台台“打包机”，然后把这些成捆的秸秆运到造纸厂。这样，既减少了环境污染又增加了废物的利用率，真是一举多得呀!怪不得今年秋收以来，家乡的天空依旧那么澄碧，空气依旧那么清新。

我一定要努力学习文化知识，将来更好地用科学技术为环保作贡献，让天空永远蔚蓝。

“拯救地球，就是拯救未来。”可是又有多少人真正去做到过。人们对满地的垃圾视而不见，街道上随意吐口香糖成为习惯；认为街道的干净与否于己无关，便袖手旁观；对于河水的污染，动物的灭绝，森林的砍伐。作为小学生的我面对这一切，从心底里说：“这样的地球很受伤，很无助，实在不应该！”

人们砍伐了一片又一片的森林。建起了许许多多的高楼大厦，开发了不计其数的房子；可是，谁又会想过那失去的森林。新闻上时不时报道某某工厂排出了废水废气，超标污染了环境；那工厂的人可否曾想过，这样做的后果会对地球有多大的伤害，对地球的寿命更加的短暂呢？

现在的地球在哭泣，因为河水从清澈到浑浊；让蔚蓝天空变成了到处是阴霾笼罩；树木由森林变成了填鸭似的屈指可数。人们那保护环境的决心去哪儿了，那绿化造林的思想又去哪了？

有一回，在超市的厕所里。水龙头“哗哗”的声音不绝于耳，白花花的水就这样流淌了下来。我想：“又是哪个马大哈不关水龙头。于是，我走了过去，把水龙头关紧了。”节约不仅是一口号，更应该从爱惜每一滴每一点水做起。更要树立“节约用水光荣，浪费用水可耻！”的观念，时时处处注意节约用书。

虽然我是一名小学生，但我同样可以为环保做些力所能及的事。去年的植树节，我便和妈妈到大屏障森林公园参加了植树。虽然只有寥寥可数三棵，但我想：三棵虽少不能带来什么可观性的代表，但每个人都参加进来那就是可观的成果。那我们又为地球争取到了多一点的呼吸空气的来源！

“超载的地球迅速疲倦着；忧郁的地球急剧苍老着；似重伤般的哭泣着。几乎可以看到的只是——漂浮宇宙的一口悬棺！”这是李松涛《拒绝末日》的诗句。是啊！如果我们再污染环境，乱砍伐树木，那么地球就要真的灭亡了。

在此，我想向广大的市民呼吁一声：热爱地球吧！善待地球吧！善待人类吧！

“滴答，今天晚上的作业可真多！”连钟都同情我，这不！10点了！不过忍着总算是写完了。“我好困啊！”不知不觉我就进入了梦乡……

“你好！”只听到背后传来一阵响声，我回头一看“哎！这不是东海龙王吗？”那个人回答到“是的我就是东海龙王。”我说：“找我有事吗？”东海龙王笑着说：“你太幸运了！”“此话怎讲？”我疑惑不解的问。龙王说：“我们每五年在世界各国挑选一个幸运儿到东海参观，万里挑一，难道你还不够幸运吗？”我激动万分：“是啊！我的确很幸运！”说完，我和东海龙王就腾云驾雾来到了东海龙宫。龙王盛情的款待了我，带我到水晶宫玩，去大厅吃了一顿丰盛的饭……过后龙王带我去了后花园。

“哇！好美啊！简直是人间仙境！”我赞叹到。不见龙王沾沾自喜，龙王却长叹了一口气：“唉！”我问：“龙王你怎么了？”龙王把心中的忧愁说了出来：“这里曾经何止这样？过去这里是世界最大最美的花园不比天上的御花园差，而如今……唉！”龙王又叹了一口气，我说：“怎么回事？”“这不是人们给闹的？你现在看到的只是它的四分之一，自从女娲创造了人类以后，东海龙宫就成了人们的旅游景点，人们把吃了的东西都仍进了大海里，所以都被垃圾给覆盖了。”我听了心里甚为同情我对龙王说：“就没有解救的办法了吗？”“有到是有……”我心急如焚：“什么办法？”龙王说：“你知道孙悟空吗？”我说：“当然知道！”“你只要借到他的定海神针，就能把垃圾搬走，不过那要比登天还难应为他是不会轻易把定海神针借给你的！”我说：“再难我也要去借！”“好！”

刷！我还没有反应过来，就到了一个神秘的洞口前，我抬头一看上面写着金光闪闪的六个大字“花果山水连洞”我想：这一定就是孙悟空的住所了，我轻轻的敲了敲门，大门就打开了我走了进去，看到孙悟空坐在那儿闭目养神，孙悟空说：“你有事吗？”我说：“大圣，如今人们的环保意识太差了，地球已经是千疮百孔了，我想借你的定海神针把地球上的垃圾搬走。”孙悟空笑到：“你能拿动我的定海神针？我何尝不想呢？可是连我也无能为力了。”我大吃一禁怎么会这样呢？孙悟空说：“垃圾太多了。不过如果让人们感受一下垃圾的滋味我想可能会好一些。”忽然眼前一片漆黑只听见人们的尖叫声和哭泣声……

滴滴！闹钟响了，把我从睡梦中叫醒，我满头大汗，心想：“如果真的变成那样世界会怎样的乱啊！也许这是给我们的一个警告吧！人们你们想看到未来是那个样子吗……如果不想好！让我们携手共进维护美好的明天！

The protection of the environment is everyones responsibility!(标题)

Taking good care of our environment is very important.Wherever you live,You can do something around your neighbourhood.

its our duty to keep our environment clean and tidy.You might ask yourself,"have I picked some rubbish and thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"

If everyone makes a contribution to protectingthe environment,the world will become much more beautiful!

Nowadays, smart phone has been part of our life. We can see people lowing

down their heads and playing smart phones all the time. When people are walking

on the street, the traffic regulations are no longer their first concern. It is

so dangerous for them to keep their attention on the phone. Dutch officers

figured out a new rule to let people realize the traffic lights. On the ground,

the traffic light can be seen. What a smart idea. When people are watching smart

phones, they can see the lights, too. At the same time, we need to think about

the problem that whether our life is controlled by the technology.

我们的祖国虽然资源、物产比较丰富。可是，你知道吗?光光这些都还不够，更重要的是要注重环保!

Although our motherland is rich in resources, products. But, you know? Only these are not enough, it is more important to pay attention to environmental protection!

我觉得，政府应该多多提倡环保，多多参与环保工作，为环保做贡献，组织好环保是最关键的。你们说，是吗?

I think, the government should take to promote environmental protection, actively participate in the environmental protection work, make a contribution to protecting the environment, organization of environmental protection is the key. You say, yes?

首先，应该告诉市民，要关注每一件环保的事，积极做环保工作，不要随手扔垃圾、看到垃圾要及时捡起。其次，要把废旧电池该扔哪的问题解决好，应该把这件事给做得更完善：在一些地方分放一些回收废旧电池的筒，每天都有专门负责的人去取。这样一来，不管是住在偏远地区，还是住在热闹的地方，都可以很方便的把废旧电池处理了，再也不会发生人们不知道废旧电池怎么处理，就把废旧电池扔进垃圾箱里的事了。最后，政府应该增加一个环保工作者的职务，让更多的人投身于环保工作当中!

First of all, should tell the people, pay attention to every green thing, to do environmental protection work, do not readily throw garbage, garbage to pick up see. Secondly, to throw the waste batteries which to solve the problem, should put this thing to do better in some places put some recycling waste batteries, cylindrical, every day there are responsible for people to get. In this way, whether it is to live in the remote areas, or in the bustling place, can be very convenient to the handling of used batteries, and it wont happen again and people dont know how to deal with the waste batteries, waste batteries thrown in the garbage again. Finally, the government should increase a environmental protection worker job, let more people involved in environmental protection work!

为了环保，行动起来吧!

To be environmentally friendly, action!

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

保护生态环境

啄木鸟一家住在一座树木茂盛的大森林里,那里的环境清新幽静,许多路过森林的动物在这里安居乐业,静寂的大森林渐渐变得热闹起来。

一天,沉睡的小啄木鸟被一阵奇怪的声音给吵醒了。

啄木鸟妈妈带着小啄木鸟顺着发出的声音寻找声音的源头。它们飞到森林最高的一棵树上向下眺望,看见一个伐木工人拿着斧头砍树,嘴里还叼着一支香烟。

小啄木鸟好奇地问:“妈妈,这个人是谁?他为什么要砍树呢?”妈妈叹了一口气,沉痛地说:“他是一个伐木工人,是专门砍树的。这个人呀,脑袋里有两只虫子,一只叫做‘自私’,还有一只叫做‘贪婪’,它们才是砍树的罪魁祸首,就是这两只虫子在作怪,是它们使人变得越来越坏。”

小啄木鸟听了妈妈的话,非常生气,它愤愤地说:“真想啄开那个人的脑壳,看一看里面到底有什么虫子!用尖尖的嘴巴啄掉那一支烟头,用爪子撕成碎片。如果烟头被他扔到草丛里,一定会引起火灾的!”可是,那是不可能的,至少啄木鸟妈妈不会让孩子冒这个险的。

哎,如果人类再不注意保护环境,失去家园的就不仅仅是鸟儿了。任何降临到动物身上的是,终究会降临在人类身上。
