保护自然英语作文通用2篇 作文怎么写20篇

早晨，太阳公公把灿烂的光芒带给大家。有一群孩子吃着东西走来，他们踩在小草的头上，小草哭了；他们用力的栽花，华人的爸妈伤心落泪；他们用手把我的胳膊摇来摇去，我说好痛啊！他们把脏的垃圾扔进泉水上，泉水不再叮咚叮咚的叫了。他们不止是这样，还叫砍树者把我的同胞砍了，我看到一个个同胞被砍了我心里非常痛苦，我希望这一切不是真的，但事实始终是事实，我忍不住落泪了。

过后，雨姐姐忍不住也落泪了，她把泪水落在小草上，抚摸着它，安慰着它别哭；她把泪水落在花儿上，说被：你的儿女不会有事的。她把泪水落在我的头上说：别难过了，什么都要经过磨练才是人生最大的幸福。她把泪水落在泉水上说：你的演奏的乐曲是独一无二的，要努力哦！

树上有生命的，大自然的每一件事物都有生命。我呼吁人类：请不要再伤害我们了，我们也怕疼。如果你是我们，被人砍了，你会看新吗？如果你被人踩在头上，你会快乐吗？请你们爱护大自然把，做一个好公民！

There are more and more endangered animals at present,so how to protect them has been our task of top priority .Its wrong for people to hunt animals for their meat and feather,for they are our good friends.

目前有越来越多的濒危动物,所以如何保护他们一直是我们的重中之重的任务。是不对的人猎杀动物的肉和羽毛,因为他们是我们的好朋友。

我们应该保护他们,而不是杀死他们。大熊猫,这是濒危动物之一,生活在森林和住在竹lealves。他们可以安全地生活在自然保护区。我们应该停止杀害动物和保护他们。

Our modern city is too crowded， and to solve the problem， three proposals are put forward. Most people believe that we should fist practise the policy “Late Marriage” and “One Couple， One Child” in order to reduce the birth rate. Secondly， the city government must have a tight control over rural people entering cities to engage themselves in trade or do various physical jobs so as to lessen the pressure on the city caused by the increased population. Finally more and more people suggest that living blocks with shopping centers， schools， hospitals as well as cinemas and theatres round them or even satellite towns should be built in city suburbs or the countryside round the cities. In this way city citizens will be encouraged to move there to live and work. If these three proposals are well carried out， the city population will be greatly reduced.

我们现代城市太拥挤了，要解决这个问题，提出了三点建议。大多数人认为我们应该在政策上“迟婚”和“一对一”，以降低出生率。其次，城市政府必须严格控制农村人口进入城市，从事贸易或从事各种体力劳动，减少人口增长造成的压力。最后，越来越多的人建议，居住在购物中心、学校、医院、电影院、剧院等生活街区，城市郊区或郊区的城市应该建在城市郊区或城市周边的城市。在这个方式中，城市居民将被鼓励在那里生活和工作。如果这三项建议都很好地实施，城市人口将大大减少。

[保护环境英语作文如何减少城市污染

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.

对人有益的动物有很多，例如有蜻蜓、青蛙等等。

There are a lot of useful animal, such as dragonflies, frogs and so on.

我们先说蜻蜓吧，它是益虫，它对人的益处可多了。它生活在小池子旁边，捕捉害虫。有些人，捉蜻蜓，捕蜻蜓，捉住后到处卖。我们应给立一个保护蜻蜓法，如果他们再敢捉蜻蜓，捕蜻蜓，就是知法犯法，交给警察叔叔处理。

We first dragonflies, it is good, it can be more benefit to the people. It lives in the small pool, to catch pests. Some people, to catch dragonflies, catching dragonflies, caught after selling everywhere. We should give up a dragonfly, if they dare to catch dragonflies, catching dragonflies, is to break the law, to the police uncle treatment.

青蛙也不例外，它也是捕捉害虫的能手，不过，它生活在庄稼附近的池子旁边，有时候，它也到庄稼地，旁边捕捉害虫，人们都称它保护庄稼的好帮手。有的小朋友，到池子旁边，捕捉青蛙，回家后，吃青蛙。我们应该在池子旁边树一个牌子，上面写着“保护青蛙，人人有责”，这样就不会有人捕捉青蛙了。

The frog is no exception, and it is also catch insects but it lives in crops near the pool, sometimes, it is also next to catch insects to crops, crop protection, people call it a good helper. Some children, into the pool, catching frogs, after coming home, eat a frog. We should be in the pool next to the tree a sign that read "protect the frog, is everybodys responsibility", so no one will catch frogs.

如果没有这些有益动物，害虫就会增多。这样，连农药和灭害灵都不行了。我们应给共同保护动物。

If none of these beneficial animal pests will increase. So, I can not even spirit pesticides and pest. We should to protect the animal together.

Last Friday, a chance encounter changed me and my familys life greatly.

After school, I was about to enter my apartment building when a little dirty dog, lying beside the du，stbin, caught my eye. He looked extremely weak. Immediately the homeless dog filled me with sympathy. So I bent down and held him in my arms. I rushed him upstairs and right away fixed him some food. Then, I gave him a bath. After the bath he looked energetic and refreshed. What a lovely dog!

When my parents got home, I asked if I could keep the dog. To my surprise and happiness, they agreed. From that day, he has become a member of our family. Everyone has enjoyed his company. My parents walk him often. He and I play joyfully.

Looking at the cute, happy dog today. I realize that I did the fight thing. I brought him to a warm, loving home and he has brought us great happiness and laughter.

“哇，快看哪，这棵树长出新芽了！”“是啊是啊，好漂亮啊！”我循声望去，只见树下围着一群小孩子，正站在树下，仰起脖子，美美的欣赏这树上的新叶。是啊，这棵树真的很美，碧绿的叶子，青翠欲滴，微风拂来，树叶儿沙沙作响，似乎在为春姑娘的到来而喝彩，时不时的，会有几片叶子飘落下来，在空中划起一道道优美的弧线，便落进了大地母亲的怀抱中。一阵微风吹来，拂过我的脸，吹起我的发梢，当我伸出手，想要将它捉住时，它却又不见了，呵，是风姑娘在和我玩捉迷藏呢！我将目光收回，不经意间，我的目光瞥见了路边的一个红色的塑料袋，被风吹得沙、沙的作响，它躺在草丛里，似乎在等待，等待有人将它捡起，可是过往的路人却都没有发现它的踪迹。又似乎在呐喊，在春风中，呐喊。我走过去，走到马路边，弯腰——伸手——拾起，再将它扔进它的归宿——垃圾桶。

转身，发现妈妈正站在我的身后，她微笑地看着我，朝我竖起了大拇指，我自豪地笑了，摆出了一个胜利的手势。春风再次抚摸我的脸，温柔的好像妈妈的手一般，不知何处飞来了几只小鸟，在我头顶上叽叽喳喳叫个不停，哦，我知道了，它们正替那只塑料袋感谢我呢。我飞快地跑回了妈妈身边，妈妈微笑着问我：“你知道塑料袋对环境的影响有多大吗？”这倒把我给问住了，我打开电脑查找，哇，每个塑料袋的自然分解需要200年以上，会污染周围的土地和水质，全国每年耗费掉的塑料包装袋，它在生产中所消耗的原油超过1000万桶，而处理时要耗费的电量更是大得惊人啊！一个小小的塑料袋，竟如此大的危害，街上满地的垃圾，将对环境有多大的影响啊！每年的6月5日，是世界环境日，但是，并不只是6月5日，我觉得，每一年的每一天，对于我们来说，都是世界环境日，每一天，我们都要让小草微笑，让白云欢呼，让风儿将我们的欢乐，捎去每一个角落。

保护环境，是我们每个地球人的责任。不可推卸

Children, you grabbed the small tadpoles right, you must know that tadpole grew up to become small frog, the frog can eat insects, so the frog is our humans good friends. We should protect it, not hurt it. But some hotels are also sold the frog meat? Once, dad and his friends took me to dinner. A waiter said: "you see, this is we store the launch of new specials, stir flogs ball". "Chicken is what ah?" I curiously ask, "chicken is the frog." The waiter said, with a smile. I was very angry, because they hurt our good friends-frog! Another thing, he makes a big inspiration. One day, when I finish school, saw a man at the school gate at little chicks must sell, and I will have mercy on them. Because the little chicks must first came to this world, away from the mother, away from the mother love and mother warm embrace, and this is what they faced starved to death, the risk of freezing to death. At that time I thought: we humans are so happy! When you see here, did you see to protect our human friends-animals!

小朋友，你们抓过小蝌蚪吧，你们一定知道蝌蚪长大要变成小青蛙，青蛙可以吃害虫，所以青蛙是我们人类的好朋友。我们应该保护它，而不是伤害它。 可是有些饭店还卖青蛙肉呢。有一次，爸爸和他的朋友带着我去吃饭。一位服务员过来说：“您看，这是我们店新推出的特色菜，爆炒田鸡球”。“田鸡是什么 呀?”我好奇地问，“田鸡是青蛙。”服务员笑着说道。我当时很气愤，因为他们伤害了我们的好朋友——青蛙!还有一件事，他对我有很大的启发。一天，我放学 的时候，看见一个人在学校门口卖小鸡仔，我好可怜它们。因为小鸡仔刚来到这个世界上，就远离了妈妈，远离了母爱和妈妈温暖的怀抱，这也使它们面临着饿死、 冻死的危险。当时我想到了：我们人类是多么幸福啊!当你看到这里时，你是不是明白了要保护我们人类的朋友——动物呀!

When I was very small, I lived in my hometown. My grandparents raised two

dogs, and I liked them very much. I watched them grow up from the little animals

to the big dogs. Every time when I leaved home for school, they would follow me

for some distance. When I walked a little far away, they would turn home. When I

went home after school, they would wait for me in the door and swayed their

tails. I knew they were welcoming me home. They were like my family members and

I learned that animals are part of our nature. We should protect them. We can

create a harmonious society.

In particular, is the giant whale mass stranding of whales is not uncommon, even in the same group of whales stranded in a few days in a row, but because it has always been hard to understand. According to the scientists speculate, as the whale to have a strong group of marine animals, and the scope of activities near the coast, so there are two possibilities: First, the leading whale sick, toward the beach, the other whales also customary to follow the whale to the Forward setting; Second, the whales chasing prey into the bank. When one or a few stranded whales, other whales will follow suit or to try to rescue, resulting in a large number of whales stranded at the same time on the same piece of the beach.

走进自然，亲近我们身边的自然，就会发现：我们身边的一切都是美好的。

——这是我进凇谊中学来的第一次秋游。

进入这公园，路两旁的大树仿佛在整齐地排队。

蓝天中映衬着一尊巨大的石雕，我走近一看，介绍牌上写着四个大字：飞向永恒。再详细看下面的介绍，才知道这是一尊石雕钟，我仔细看了看它所指的方向就清楚的知道了时间。我想：这真是一尊杰作呀!

走过一座宽敞的桥，放眼望去，哈。风景如画!

花草郁郁葱葱，青翠欲滴。微风吹来，轻轻的摇动。

……

走累了，找个阴凉的地方坐下来，吃一点东西。又来到了迷宫，这迷宫可真绕!走着走着，我就没有了方向感。还是队长带着我们走了出去。

哈!这里仿佛一个大花园一朵朵花儿簇拥着，太阳照着他们，照着我们的一个个笑脸……

我们爬上了一座观光塔，它的形状可真怪!像一棵古老的巨树，从上面俯视整个公园，一切都是那样的美丽!

躺在草地上，仰望天空，蔚蓝的天空漂浮着白云。

在这样一个舒适的空间里，我自由玩耍，我观望风景，我自由放松……在这样的活动中，我深切体会了：亲近自然，保护自然!

活动结束了，不言而喻，我当然意犹未尽。那美丽的风景，轻松快乐自由的玩耍，我喜欢!

人类，是地球上最聪明的动物，被列为高级动物，可我却常常想，人类真的是最聪明的动物吗？那为什么他们还任意践踏自己赖以生存的家园呢？如果人人从自己做起，为地球献出一份自己的力量，地球该有多么棒啊！就拿环境来说说吧！现在的环境较差。

人们乱扔垃圾。那在冰冷的地上的垃圾，它们在哭泣，在冰冷的小路上打颤，它们想回到自己的家──垃圾桶，人们，想想，它们该有多可怜啊！来来往往、形形色色的人，从他们的身上踩过，却视而不见，香蕉皮那滑滑的汁液，就是他的泪水；牛奶瓶”咔啦“的响声，是他在哭诉；漫天飞舞的白色塑料袋，他在寻找回家的路……人们破坏生态环境。

人类肆意砍伐树木，换来了一栋栋高楼洋房，换来了各式各样的工具，可却破坏了大自然赠予人类的”生命之被“；人类创造了无数酒楼和工厂，虽然这方便了大家，可排放的污水废气却污染了环境；人类无休止的浪费水资源，却不知，”缺水“的脚步正在日益逼近；人类为一己私欲猎杀珍惜动物，同时也在破坏自然界的生态平衡。龙卷风的来临，是风爷爷的咆哮，他在对人类的污染表示不满；海啸的发生，是水妹妹在哭泣，人类的行为使她恐惧了。人们制造噪音。

许多人开着汽车，在大马路上”嗒嗒“的直按喇叭，仿佛这是件十分光荣的事，按得还十分有劲儿呢！甚至还闲着没事在马路上神气地哟呵一声，叫骂一声呢！在家的居民们每天都听着这”交响曲“他们好受吗？多吵呀！别只顾着自己呀！假如人人献出一份力，世界就会很美好。

所以我认为环保应该从我做起，从每件小事做起。每人捡起自己扔的纸团、水果皮……小路上，街道上，就会少许多垃圾，垃圾们回到了各自的家，也不再哀鸣、哭诉了，都在家里开心的”笑“……大家都不再污染环境，坚持步行，还能锻炼身体哩！没有了噪音，城市是不是安静了许多？在家里的一些老年人，都图清静，他们是不是更舒服了呢？世界有了环保才会美丽。

嫩绿的小草在地上舞动，在跳”民族舞“；小花做小草的舞伴，和他一起翩翩起舞；蝴蝶在空中自由的飞翔，时不时地为一朵可爱的小花朵采蜜；大树挺立在风中，仿佛在保护着这”一草一花一蝴蝶“，保护着这美丽的环境。我们期待我们的家乡青山绿水、绿树成荫；我们期待我们的地球永远春意盎然、生机勃勃。是的，我们只有一个地球，爱护我们的家园，用心付出、用心感受，把环保的树种在我们的心中，总有一天它会长成参天大树！

同学们，地球妈妈是一艘浩瀚无边的宇宙飞船，而我们人类则是这飞船的乘客。我们的人本来就已经多得让地球妈妈撑不住了。可是人类还是肆无忌惮的破坏。

大家想一想，我们渴了，有水喝，那地球妈妈渴了呢？河水干涸，几个月不下一滴雨……如果人类不从现在节约水源，保护水资源，人类看到的最后一滴水将是自己的眼泪。

以前，人和动物和睦相处。可是，现在人们不保护动物反而去屠杀东北虎，拔取象牙……地球上最后灭绝的动物就是我们人类。

同学们啊，现在每个地区的“绿色”都“下降”了许多。如果有一天，惹得大地妈妈生气、伤心，就发生大灾难：海啸、山洪、泥石流……同学们，树木拥有绿色，地球才有脉搏。

蔚蓝的大海，本来是海鸥的乐园。可是巡弋的战舰和水雷成了不速之客，绿茵茵的草地，本该滚动着欢乐的足球，可是如今散落着地雷碎片，阻挡着孩子们奔跑的脚步……战争把我们本该欢乐的家园搅得不安宁。我呼吁，让战争停止，让那些本应该享受生活的人和我们一样享受！

保护环境、制止战争，让地球妈妈重生。

[保护环境英语作文60字

我们要随时随地的保护环境卫生！假如大家都不保护它，它就会被垃圾污染，以后大家吃了这些不好的食品和喝了不干净的污水大家就都会生病的，所以我们不可以让这种事情发生，现在我提昌：“保护大自然，爱护身边的每一寸土地让他们变得更加干净，更加洁白，大自然也是我们的地球妈妈呀！我们的妈妈生病了，大家还要细心，努力的照顾她！”

身边的环境是最重要的，我们要在家庭里，学校里做一个讲文明，懂礼貌的好孩子。我们必须要学会怎样保护环境。环境这两个字，对我们来说并不陌生，他们代表着什么意思呢？就是要告诉我们要保护环境，我们大家要有一个良好的生存环境。

所以，就让我们行动起来吧！保护环境，人人有责，从一点一滴的小事做起，做到爱护花草树木，做到“只捡不扔”，让大家都主动，自觉的做起来，好好保护我们这个美丽和谐的大家园吧！大自然的每一件事物都有生命。我呼吁人类：“请不要再伤害我们了，我们也怕疼。假如你是我们，被人砍了，你会开心吗？假如你被人踩在头上，你会快乐吗？请你们爱护大自然吧，做一个好公民！”

保护大自然吧！

同学们，我们走在大自然中是否能听到万物凄惨的声音，人们啊请放过我们吧！

为什么人们要这么要这么残忍的去伤害大自然呢！下面我们来听听树木的倾诉吧：你们看，我身上的叶子吸附了多少灰尘，并且我的树身还可以做家具。人们就是利用我们去挣钱，大量的捕杀我们的家族，去卖成钱，他们自己拿着钱为所欲为，他们这中自私的行为应该受到大家的责骂。他们可想过假如有一天没有了树木，会不会引来洪水，人们的生命是否受到威胁，到那时后悔就来不及啦！我们在换一个角度想想，假如人们特别爱惜我们这个家族，也同样保护大自然，当洪水来到时，我们还可以阻挡洪水，也同样保护了人们的生命。这样难道不好吗？伟大的人们请你们放过我们吧！！放过我们也同样是放过你们自己。

水资源的污染对人们的身体也是有坏处的。你听啊！小溪在说话呢！哎！我身上是越来越脏拉，而且身体也是一天不如一天啦！这些都是人们对我们的破坏啊！求求你们放过我们吧！你们吃的水也是我们提供的啊！如果我们受了污染，你们吃饭或喝水的时候病菌就会从你们的口中直泻到你们的身体上，你们就会得个种疾病，随时危害到你们的生命，所以我请求你们不要在把废水排放到我们这里来啦！不要在危坏我们啦！

啊！大自然啊！你什么时候能在回到原来的面目呢？人们什么时候能像保护自己一样的去保护大自然呢！求求你们，放过我们吧！

[保护大自然为题目的作文

As we all know the environment around us is getting worse and worse .In some places, we can’t see fish swimming in the river or trees on the hills. Some people even have no clean water to drink. So I think we must do something to protect the environment.

But what can we do? How to protect our environment? For example ,we can go to school on foot or by bike. We can use shopping baskets not plastic bags when we go shopping and we can use both sides of the paper when we write

In a word ,if everyone pays more attention to our environment ,there will be less pollution and our life will be better . “There is only one earth”, I hope everyone will protect our environment well.

What Can We Do for the Environment our environment is becoming worse and worse what can we do for the environment? I think each of us can do a little bit to help with this problem.

The first thing we can do is to use cloth bags instead of plastic bags when we go shopping. It helps to protect the environment. The second thing we can do is to reuse the old textbooks as possible as we can. We should also never forget to turn off the lights when we leave the classrooms in order to save energy. What’s more, it would be better if we walk or ride a bike to school. We should try our best to reduce pollution and waste. In fact, even the simplest everyday activities can make a real difference to the environment. I believe we can make the world a better place to live in.

我们都知道我们周围的环境变得越来越糟。在一些地方,我们不能看到鱼在河里游泳或树木在山上。一些人甚至没有干净的水喝。所以我认为我们必须做些事情来保护环境。

但我们能做些什么呢?如何保护我们的环境?例如,我们可以步行去学校或骑自行车。我们可以使用购物篮子而不是塑料袋当我们去购物时,我们可以使用双方当我们写论文的

总之,如果每个人都更加关注我们的环境,将会有更少的污染和我们的生活将会更好。“只有一个地球”,我希望每个人都能保护我们的环境好。

我们能做些什么对环境我们的环境正变得越来越糟的环境我们能做什么?我认为我们每个人都能做一点帮助解决这个问题。

我们能做的第一件事就是使用布袋而不是塑料袋当我们去购物。它有助于保护环境。第二件事我们可以做的就是尽可能的重用旧的教科书。我们也应该永远不要忘记关灯当我们离开教室以节约能源。更重要的是,它会更好,如果我们步行或骑自行车上学。我们应该尽力减少污染和浪费。事实上,即使最简单的日常活动也能对环境产生一定的影响。我相信我们可以让世界变得更美好。

Once man did not have to think about the protection of his environment。 There were few people on the earth， and natural resources seemed to be unlimited。Today things are different。 The world has bee too crowded。 We are using up our natural resources，and polluting our environment with dangerous chemicals。 If we continue to do this， human life on earth will not survive。 We realize that if too many fish are taken from the sea， there will soon be none left。 Yet，with modern fishing methods， more and more fish are caught。We know that if too many trees are cut down， forests will disappear。 Yet， we continue to use powerful machines to cut down more and more trees。 We see that if rivers are polluted with waste products， we will die。 Yet， waste products are still put into rivers。

过去，人们不必担心保护环境的问题。因为那时地球上人口稀少，自然资源似乎取之不尽。如今，一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源，有毒化学制品的使用也正污染着环境。如果我们继续这样下去，地球上的生命将不复存在。我们都明白如果从海里捕捉太多的鱼，海里就不会再有鱼了。可是，现代化的捕鱼技术使得捕鱼量越来越大。我们都明白如果砍伐太多的树木，森林就会消失。可是，我们仍旧使用强大的机械砍伐越来越多的树木。我们都明白如果河水被废弃物污染的话，我们仅有死路一条。可是废弃物仍然源源不断地进入河里。

We know that if the population continues to rise at the present rate， in a few years， there won＇t be enough food。What can we do to solve these problems?If we eat more vegetables and less meat， there will be more food available。 Land for crops feeds five times more people than land where animals are kept。Our natural resources will last longer if we learn to recycie them。The world population will not rise so quickly if people use modern methods of birth control。

我们明白，人口继续照此刻这个速度增长的话，不出几年，就会发生食物短缺。我们该如何解决这些问题呢?如果我们多吃蔬菜，少吃肉类的话，我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。如果我们学会再利用的话，自然资源就能持续更久。如果人们使用现代化的生育控制方法，世界人口就不会增长如此迅猛。

Finally， if we educate people to think about the problems we shall have a better and cleaner planet in the future。

最终，如果我们能够教育人们都意识到这些问题的话，未来我们就会有一个更好、更洁净的星球。

We need to protect wild animals, because we protect wild animals, wild animals will be very friendly to us.

Like the swallow, swallow can help us to eat the pests in the field. If we human beings killed to catch them, they will eat mosquitoes that often to scratch faze us, let us better life? Without the swallow around us become many insect pests, these pests have great harm to our human!

I have an example. For example the frog, the frog can also help us to eat the pests in the field, can be said to be the police in the field. Once we kill them, not the frog, the pests in the field more and more, pest constantly eat vegetables, dont we will have a good harvest?

I have an example. Such as w, w is a doctor in the forest, it can help us to eat the pests in the tree, the tree back to health. We killed them, pests will be more and more trees, trees will slowly decrease. No trees on earth, floods, earthquakes.

My last an example. Such as owls, catch rats, the owl is good for us human beings, human is often hunt them. No owls, voles will increase. Rats ate the crops and vegetables is more, we human beings did not have a good harvest.

So, we need to protect more than animals. At the same time, we also need to protect other wild animals!

我们要保护野生动物，因为我们保护野生动物，野生动物对我们人类也会很友好。

比如说燕子，燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们，它们会吃掉那些常常来搔扰我们的蚊子，让我们更好地生活吗?没有了燕子，我们的周围变得很多害虫，这些害虫对我们人类有很大的坏处呀!

我还举个例子。比如说青蛙，青蛙也能帮我们吃田里的害虫，可以说是田里的警察。我们支捕杀他们，一旦没有了青蛙，田里的害虫越来越多，害虫不断地吃菜，难道我们会有美好的丰收吗?

我还举个例子。比如说啄木鸟，啄木鸟是森林中的医生，它可以帮我们吃掉树里的害虫，让树恢复健康。我们杀害它们，树木的害虫会越来越多，树木会慢慢地减少。地球上没有树，会发洪水、地震。

我最后举个例子。比如说猫头鹰，猫头鹰捉田鼠，是对我们人类有好处的，人类却常常捕猎它们。没有猫头鹰，田鼠会增加。田鼠吃的庄稼和菜就更多了，我们人类一样没有好的收成。

所以，我们要保护以上的动物。同时，我们还要保护其他的野生动物!

同学们：

大家好！我演讲的题目是《人类，请保护大自然吧》。

大自然是人类生命的起源地，也是动植物的出生地、栖息地。所以，人类应该竭尽全力地去保护大自然，维护大自然生态系统的平衡。

昨天，我在手机上看到几张图片，这些图片给了我很大的震撼——海边都是人类乱丢的垃圾，海面上也漂浮着塑料袋、易拉罐……

还有一张森林里有许多高大挺拔的大树都被砍伐了的图片。

在一只已经死亡了梅花鹿的肚子里，发现了一个塑料袋。因为人们把装东西的塑料袋随手乱扔，被梅花鹿误食入嘴中，导致窒息死亡。

还有一些关于海洋生物的信息。原来，海洋里的生物很多，也很美，有凶猛的，有温顺的，有庞大的，也有细小的，这些生物都有它们各自的生态循环，可因为人类的捕捞、猎杀，导致大多数海洋生物系统无法循环，更严重的是会导致许多物种濒临灭绝或已经灭绝了。

相比之下，大自然都已经这样了，可某些人并没有要停止破坏的意思。有一天，我走在放学路上，看见有几名小学生在小区的小树林里爬树折树枝玩，我走上去制止他们这种可恶的行为。可他们并没有要停止的意思，还恶狠狠地对我说：“要你管，赶紧走开，小心我们揍你！”因为当时时间已经不早了，我又是独自一人，不好说什么，就离开了。可是，这种行为真是太可恶了，这种人就应该受到惩罚。

大自然是一个非常巨大的生态循环系统，人类和动植物都离不开它的。从现在起，我们应该尽自己最大的“力量”去保护大自然！

谢谢大家！

It is undeniable that the worsening environment has become the biggest concern of the present-day world. Land resources are dwindling because of water loss and soil erosion. Waste gases poison the air we breathe. The rivers and lakes are polluted by waste dumped in them from factories. It is probably no exaggeration to say that deterioration of the quality of the environment threatens the existence of mankind itself.

Some people are of the opinion that the environmental problem is the price we have to pay for economic development. But I do not think that this argument is valid. After all, what is the point of economic growth if peoples lives are adversely alfected by worsening environmental pollution ?

不可否认环境恶化已成为当今世界最大的问题。土地资源在不断减少,因为水土流失。废气污染着我们呼吸的空气。河流和湖泊被工厂的 倒出来的废弃物所污染。这可以毫不夸张地说,环境质量的恶化威胁着人类的生存。

有些人认为环境问题是我们因为经济发展而必须要付出的代价。但我不认为这种观点是有效的。毕竟,经济增长的重点是什么?如果人们的生活环境被日益恶化、被严重污染了，那还有什么意义?
