如何保护濒危动物的英语作文(实用20篇)

A thought-provoking dialogue between the mother elephant and her own child appears in the first picture. Having growing his teeth, the young elephant is eager to share the exciting news with his mother. However, after repeating his words several times, there is still no response coming from the mother. Meanwhile, the attractive caption in the second photo reads: no trade, no kill.

The above pictures unveil a hazard posed to wildlife due to the expanding scale of world commercial hunting. At least two fundamental factors could contribute to this phenomenon. The industry of commercial hunting have undergone a booming expansion (along with the growing public awareness of the merits of wildlife, which makes/), making hunting unusually profitable. Worse still, lacking knowledge regarding the significance of ecological balance, some people take the gun to chase animals insatiably (and thus cause a severe threat to all life in the world). Apparently, this trend will surely in turn endanger humankind in the long run.

(On no account should we turn a blind eye to such things.//All these factors above make it crucial to take drastic measures to protect the wildlife.) Accordingly, governments all over the world are supposed to unite to work out effective measures against commercial hunting. Additionally, people should be educated from childhood to cultivate the awareness that we and the rare wild animals share the same precious planet. I do believe a harmonious relationship between the wildlife and human beings is awaiting us if we make every effort to promote wildlife protection both nationally and internationally.

我们人类生活在地球上，地球上有许多东西需要我们保护，但是我们却没有在意。

We live on the earth, the earth there are many things we need protection, but we didnt care.

有些人不珍惜地球赐予我们的一切，例如人们乱砍乱伐，大量使用一次性筷子和乱扔塑料袋，制造白色垃圾等已经给大自然带来了许多环境问题，严重影响了我们的生活。还有大气污染，酸雨和臭氧层等带来的危害都是大自然给人类带来的灾害，人们乱砍乱伐，乱扔塑料袋和使用一次性筷子等，这些就是人们不尊重大自然而造成的，没有自然，便没有人类。这是世界一大朴素的真理，人们只会一味的抢夺自然，征服自然，只会破坏生态系统，咎由自取，使人类濒于困境。切记，保护环境就等于保护我们自己生存的环境。

Some people do not cherish the earth gives us all, for example, people cut down many trees, the extensive use of disposable chopsticks and throw plastic bags, producing white garbage has to nature brought many environmental problems, a serious impact on our lives. There are air pollution, acid rain and the ozone layer damage caused is human nature to bring disaster, people cut down many trees, throw plastic bags and disposable chopsticks, which is that people do not respect the nature and cause, no nature, no human beings. This is a big world, plain truth, people just blindly grab the nature, conquer nature, will only bring trouble to oneself, the destruction of the ecological system, humans dilemma. Remember, Protect environment is to protect our own living environment.

我们要保护这个脆弱的的地球，不要让茂密的森林，辽阔的草原和无边无际的海洋成为我们的回忆。

We want to protect this fragile earth, dont let the dense forests, vast grasslands and boundless ocean has become our memories.

现在起，我们应该保护环境，一起捍卫我们的家园。

At that time, I was on the first grade, do not understand love small animals.

That day my mother bought me two little ducks. I am very happy to put two little ducks in the box, listen to their calls, my mood is very good.

The passage mainly tells us the importance of protecting traditional Chinese culture, which is challenged or facing extinction because of the developing society and changing lifestyle. Besides, China is nationwide sparing no efforts to do it.

The protection of national and folk culture is of great significance to Chinese cultural diversity and also to the harmonious development between local economic and social development. It is reported that the Guangdong government pays special attention to protecting Chaoju，a local drama born in Chaozhou in the eastern Guangdong province.

In my opinion, some measures should be taken to protect traditional culture effectively. To start with, we should make a law to regulate the society’s performance. Besides, we should draw more people’s attention to it, for the more they know about the importance of culture protection, the stronger the support we can get from the public.

In a word, it is high time for us to treasure and develop our own valuable culture.

今天，我见到了几个在我们这，不常见的鸟类。今天，天气很好，经过昨天的雨，空气也更加清新了，天也更蓝了。早上，我早早的起来了，来到窗前，做了个深呼吸，感觉清醒多了。

我在窗前站了一会，欣赏欣赏风景，突然，传来几声鸟叫，接着，从树上飞下来依次飞下来两只鸟，定睛一看，原来是两只啄木鸟，要知道，在我们这个地方，这种鸟可是不容易见到的。这只啄木鸟有着又长又尖的嘴巴，头和脖子是棕色的，下半身是黑白相间的，很是漂亮。只见，那只鸟在左边看看，又往右边瞧瞧，着急的寻找着食物。

就在这时，又飞来一个鸽子，这只鸽子全身都是灰色的，也掺着一点白色的羽毛，也十分漂亮。可这只鸽子悠闲地踱着步子，好像胸有成竹，能在啄木鸟之前找到食物，一点也不着急。啄木鸟见鸽子这样，很是不解，便停了下来，侧着身，歪着头，不解的看着鸽子，可鸽子并不理它，照样悠闲地踱着步子。啄木鸟见他还是这样，便不再理他，继续寻找着食物，就这样，功夫不负有心人，啄木鸟找到了吃的，正要享受，有一个人正好从旁边经过，吓得他叼起食物就走，一走脖子还一前一后的好玩极了，我看得十分投入。

这时，鸽子看到啄木鸟先找到了，很不乐意，上去就要抢那个吃的，啄木鸟知道了，立马叼着食物要走，鸽子在后面紧追不舍，这追着追着，就追到了路上，让一个人看见了，就径直走过来，想要抓住他们，还好，他们俩发现了那个人的意图，吓得立马丢下食物，慌忙而逃，他们可能飞到了另一个地方，找吃的去了。

我们应该保护动物，停下对它们的捕杀。

我一向很喜欢小狗,对姥姥家的那只小狗是格外喜欢,记得有一次我回姥姥家,小狗好像把我当成了坏人,不停的汪汪的叫着,还是姥姥把狗抱开了. 小狗是一种可爱的小动物,很讨人喜欢.它四肢灵活,行动敏捷,可爱的小面孔上长着一对可爱的小眼睛,身上白色和咖啡色的毛,显得格外可爱. 它那毛茸茸的身体,漆黑的鼻子,摇来摇去的小尾巴,很讨人喜欢. 小狗吃东西的时候非常可爱,要是肉它就狼吞虎咽,要是喝牛奶,就把牛奶舔得一干二净,我帮姥姥的小狗起了一个名字,叫-----乐乐,因为我希望它快快乐乐的长大,把不高兴的事抛到九霄云外. 乐乐喜欢晒太阳,要是太阳特别好,它就会立马跑过来,你怎么逗它,它都不理你. 乐乐睡在自已的狗窝里,喜欢把狗窝放在床底下.这样既安静又方便. 乐乐爱干净,每隔几天就要冼一次澡,我喜欢给它冼澡,逗它玩,让我感到了许多的乐趣. 所以我很喜欢小狗.

今天夜晚，我和爸爸在电脑上查了对我们有益的小动物，我们在网上找到了许多对我们有益的小动物，比如：蜻蜓、燕子、青蛙、蚯蚓、蜜蜂、蛇、猫头鹰、啄木鸟等。下面就说说它们对人类有哪些益处吧!

蜻蜓生活在水边，扑捉蚊子等小飞虫，免得叮咬人畜，传播疾病;燕子是候鸟，专门扑食空中飞虫，如;蝗虫、蚂蚱等害虫;对农作物生长有益的青蛙生活在稻田里，每天能吃70多条害虫，是农民伯伯的好帮手;啄木鸟是森林的好医生，它们可以从树掏出蛀虫来，每天吃上千条害虫，好厉害啊!猫头鹰专吃传播疾病和破坏庄稼的老鼠。

这些小动物可都对人类有益的，为人类作出了贡献哦，它们都是我们的好朋友，我们一定要好好地保护它们。首先，我们要爱护环境，让这些小动物有安身之处;其次，我们小朋友还可以成立保护小动物的队伍，宣传小动物对人类的益处，告诉别人不要扑食这些小动物当然，可行的措施还不止这些，希望所有的人都行动起来，为保护好小动物献计献策。

Now, our side of the car constant more up, the environment also increasingly worse!

That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do.

For example, we can go to school by bike or walk, it can exercise.

If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment.

现在，我们身边的汽车不断的多了起来，环境也越来越糟糕!以至于我们周围的空气有很多有害物质。所以，我们要苏身边的小事做起。比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。有时间的话可以少用电梯，多爬楼梯。我们不仅能锻炼身体,也能保护我们的环境。

老虎是生活在食物链顶端的一种动物，它关系到整个生物链的平衡。因此，保护老虎不单单是保护老虎这么一个物种的问题，而是保护整个食物链完整性的问题。

目前分布于我国的四个老虎亚种（东北虎、华南虎、孟加拉虎和印支虎）中，惟有华南虎是中国独有的。19世纪以前，华南虎曾经广泛分布于以我国东南部为主的国内广大地区。20世纪后，由于自然环境变迁、战乱纷扰及人类活动影响等多方面的原因，华南虎的分布区域不断受到挤压，分布地域面积逐渐缩校直至上个世纪80年代以前，由于捕猎和砍伐森林等活动，使华南虎赖以生存的栖息地受到破坏，华南虎的数量急剧减少。

据以往调查估算，目前中国处于野生状态的华南虎仅有20至30只，养殖在中国动物园里的数量也仅有60只，这仪数量比大熊猫还要稀少。在最近的一次野外考察中，甚至没有发现活的野生华南虎个体，华南虎已接近物种灭绝的边缘。

国家林业局全国野生动植物研究与发展中心的副研究员陆军介绍说，由于动物园中的数量有限，用于交配的华南虎之间的血缘关系越来越亲近，目前有的新产虎崽已经开始出现短尾（尾巴短一结）的现象。毫无疑问，如果任由这一趋势发展下去，在不久的将来，这一世界最濒危动物将不复存在。

透过虎类这一典型的例子，我们更应该保护动物，从自己做起，从他人做起，从身边的小事做起。让我们行动起来保护野生动物，共建和平家园世界将变得更美好。

It is widely noted that lots of traditional culture is disappearing along with the development of technology. Many ancient architectures and traditional ways of living have been deserted. It seems that the traditional culture and craftsmanship will be replaced in this modern era.

The following reasons can account for the above phenomenon. Firstly, traditional technologies are always considered ineffective while the new sciences are always highly efficient, because modern science and technology facilitate both our daily and academic life a lot, with which we can save much money and time. Secondly, it is costly to protect the traditional culture, especially the maintenance and repair of the historical buildings.

In my opinion, although traditional culture is an ancient heritage, it couldnt keep pace with the development of society. It is the tide of history that the traditional culture and technology will no doubt be eliminated in the end.

The global polar bear population could decline by more than 30 percent in as little as 35 years. Thats according to a new study in The Royal Societys Biology Letters.

全球北极熊数量在35年内可能下降超过百分之30。这是根据英国皇家学会生物学快报的一项新研究。

Researchers looked at climate change effect on the Arctic Sea and calculated the likelihood of this projected population drop is 71 percent.

研究人员观察气候变化对北极海的影响，并计算出预计种群下降的可能性为百分之71。

Thats because polar bears stand on Arctic Sea ice when hunting for seals. According to NASA, even the thickest ice in the Arctic Ocean has "either thinned or melted away."

这是因为北极熊捕猎海豹时站在北极海的冰上。美国国家航空航天局表示，甚至北冰洋最厚的冰要么变薄或要么融化了。

And just this week, scientists reported sea ice levels in the area were at a record low for this time of year.

就在本周科学家报告称，该地区的海冰水平创下一年中这个时候的历史新低。

This all adds up to not great news for polar bears. With an estimated population of 26,000, the bears are already listed as a vulnerable species by the International Union for the Conservation of Nature.

这对北极熊不是什么好的消息。现估计有26,000头北极熊，已被国际自然保护联合会列为易危物种。

保护动物，人人有责!相信大家都深知这句话的意思。

从前，有一个一年级的小学生小明，他的父亲天天到外面去打猎，没时间管他的学习。因此，他的成绩一直都不好。每天晚上，他的父亲都会捕来几只动物。他的父亲这样残杀动物，小明很伤心。“爸爸，不要再杀动物了，您知道杀动物是一件多么严重的事吗?这样会破坏生物链的，到头来，受损的还是我们呀!”小明说。他的爸爸严厉的回答说“你这么小懂什么?有时间就好好弄弄你的学习成绩吧!如果不打猎，靠什么吃饭?怎么供你上学?”小明说“那我好好学习，每次都得奖学金，你是不是就不打猎了?”“对，只要你的奖学金，我就不打猎”从此，小明就天天都努力学习。果然，在初中的时候学校答应只要他考试得第一名的时候就会给他奖学金。他的父亲也信守诺言，再也不打猎了。

就连一个一年级的小学生都懂的道理，难道那么多的猎人就想不清吗?你们有没有想过，假如你是一只动物，人类无缘无故的就把你杀了，你会愿意吗?肯定是千万个不愿意。俗话说得好“己所不欲，勿施于人。”你自己都不愿意，那动物们会愿意吗?就因为捕猎，现在都有多少种动物灭绝了，你们知道吗?已经800种了，这个数字看起来是不大，但是把每种动物的数量加起来，你们知道是多少吗?你们算过吗?破坏生物链，对人类一点好处都没有。

让我们行动起来，一起保护动物，从我做起。

当这个星期六下午4时少年宫的大门一敞开，我们就像一群才长了翅膀的雏鸟叽叽喳喳地飞向自己翱翔的蓝天。对我们这一只只小鸟儿来说天空是多么湛蓝，多么地广阔呀!

忽然一个身影映入我的眼帘一只浑身碧绿脖子发蓝，身高约七厘米的小鸟。咦?它怎么会有一张小巧的嘴呢?对了，这不就是常说的红嘴相思鸟吗?遇见了一只这么名贵的鸟儿，当然要逗逗它，想罢，吹了一声响亮的口哨。就这么一晃眼，鸟儿不见了，再望望前方我又看见了那只色艳迷人的小鸟，不过，这次是在一位眼疾手快的妇女手里。我呆呆地站在一旁心里有点矛盾，到底要不要救这只小鸟呢?

等我回过神来已经有许多小孩围在了妇女的身边，每个人都想玩弄一下这个可爱的小东西，“让我来玩一下!”“能给我摸摸吗”“真可爱”“它的毛真滑!”……到等他们都渐渐散去后我与小相思鸟的目光发生了碰撞，我仿佛能感受到小鸟眼神中的痛苦与哀求。我于心不忍，但总不能坐视不管让鸟儿饱受痛苦吧?当我还在思索时又有一个调皮的小男孩走了过来抢走了红嘴相思鸟，他一边拨弄着小鸟深绿色的翅膀和小小的爪子，向前走去。小鸟似乎在发抖着，更是用一种忧伤的眼神看着我，指望有一位救星。我这才鼓起勇气向小男孩走去小声地提醒道：“快放了它吧，它也很可怜。”

结果真是出人意料，那个小男孩一声不响地推出手，慢慢地端详着这只美丽的小鸟，最后张开双手放飞了这只可爱的小鸟。我们抬头观望，天空中却不见了它的身影，耳边却响起了一清脆的鸣叫，鸟儿，是你吗?是你，在谢谢我吗?

不管怎么说爱护小动物是每一个人的责任。

I love dogs, dogs are the cutest animal ever on earth. From small and cute ones to big and fierce ones. I love all kind of them. They say dogs are mans best friends. I agree with that because dogs are royal, friendly and fun to play with. Some of them are extremely cuddly and soft to hold and hug.

Ears are very long, put up is particularly clever. It signed the front legs short and small, hind legs are fat and strong, so can only jump, can not run. Tail is also very small, almost can not see.

如果你看到了那用生命搭成的桥，你会不会放下你手中的LIE枪；如果你看到了那因同胞而死去的蚁国英雄，你会不会放下你手中灭蚁的工具。

是的，有时生命是那么的渺茫，渺茫的就象大海里的细沙。在夏天，当你在草丛中奔跑你那随脚一跳，你知道会有多少生物会从这世界上逝去吗？我可以负责任的告诉你：你那一脚对昆虫来说，就等于八磅C4炸药！八磅C4炸药可以一口气炸掉一座摩天大厦！你想象的到吗？

世界上平均每隔5分钟就会灭绝0.002种生物！地球在变暖，冰河在融化，我们美丽的地球将不再是一个家……动物的种类在逐渐减少，人类将渐渐变的孤独；如果我们还不觉悟，难道以后动物园也要用机器来制造动物吗？！

所有的少先队员们，请和我一起呼吁：爱护生命是少先队员应尽的责任，我们要珍爱生命，保护动物！

Today, Dameisha took me to see the sea, because I have never seen the sea. I was thinking of the sea all the way. I saw on TV the sea is very beautiful, I feel that the sea should be like this: blue water, spray gently lying in the arms of the sea. On the beach there grows many palm beach, lying quietly in many shells, conch. A few crabs to climb. Should be against the background of blue sky, the sky the sun, seagulls flying, this beautiful picture of you! What an intoxicated! I feel relaxed and happy.

Can be when I saw the sea of a moment, I am disappointed, the mood suddenly changed. Because my eyes of the sea is dark, is muddy, is not angry, is not confident. Some just inferiority. I know that the sea is not so, but people are polluting into this.

Now, human beings in order to live, a large number of cutting trees, cut and not planted, how many of the previous tropical rain forest, now is flat, how many trees, now replaced by high-rise buildings. Factory emissions, air pollution, and no trees to release fresh air. And plant emissions of toxic wastewater, so that water in the small fish, shrimp have been poisoned, and the river afloat smelly fish dead bodies and garbage, all this is how terrible ah!

Lets go and embrace the nature! To protect nature! Let everything in the world be beautiful.

今天，大姨带我去大梅沙看大海，因为我从来没有见过大海。我一路上都在想大海的样子。我看见电视上的大海很漂亮，我觉得大海应该是这样的：碧蓝的海水，浪花轻轻的躺在大海的怀抱中。海滩上生长着许多的椰树，海边静静的躺着许多贝壳，海螺。几只螃蟹爬来爬去。映衬着的应该是蔚蓝的天空，天空上的一轮红日，海欧飞来飞去，这景象多美呀！多令人陶醉呀！我心情轻松愉快。

可当我才看见大海的一瞬间，我失望了，心情一下子变的沉重了。因为我眼前的大海是灰暗的，是浑浊的，是没有生气的，是没有自信的。有的只是自卑。我知道大海原来不是这样的，而是被人们污染成这样的。

现在，人类为了生活，大量砍伐树木，砍了又不栽，以前有多少热带雨林，现在是平地，以前多少树木，现在取而代之的是高楼大厦。工厂排放的废气，污染空气，又没有树木放出新鲜的空气。还有工厂排放出的有毒的废水，让水里的小鱼，小虾都被毒死了，河面上浮着发臭的鱼的尸体和垃圾，这一切又是多么的可怕呀！

让我们去拥抱大自然吧！去保护大自然吧！让世界上的一切都变得美好。

Water is the source of life.We cant live without water.However,with the increasing population and industrial development,water pollution has become a serious problem.Large amounts of wastewater go into rivers and seas directly without being treated,which can be dangerous to people.Also lots of people pay no attention to saving water in daily life,while in some place water is badly needed.

Its time for us to take some measures to improve the situation.Factories should treat the wastewater before letting it go into rivers.We can play a positive role in saving water.For example we can reuse the water for wishing rice to wash vegetables and then clean a mop.

henry ford didn’t always pay attention in school. one day ,he and a friend took a watch apart. angry and upset, the teacher told him both to stay after school. their punishment was to stay until they had fixed the watch. but the teacher did not know young ford’s genius. in ten minutes, this mechanical wizard had repaired the watch and was on this way home..

ford was always interested in how things worked. he once plugged up the spout of a teapot and placed it on the fire. then he waited to see what would happen. the water boiled and, of course, turned to steam. since the steam had no way to escape, the teapot exploded. the explosion cracked a mirror and broke a window. the young inventor was badly scalded
