关于保护动物的英语作文【最新20篇】

昨天放学时，天气非常炎热，我下楼没看见爷爷，就借同学手机打了个电话，然后我等了几分钟，爷爷就来了。

我上了车一边与爷爷闲聊，一边看着路边的风景。

突然我看到公路上有一个毛茸茸的小东西，是老鼠吗?怎么可能，怎么可能有这么大的老鼠，我又仔细看了看，这小东西正摇着它那蓬松的大尾巴，呀!是松鼠!太神奇了，居然在大马路上看见了松鼠。它好像要过马路似的左顾右盼的，好像不怕人，我们电瓶车走过，也没有引起它的恐慌。这时一辆路虎朝它飞驰而来，我心里一阵担忧，心跳顿时加快，仿佛有什么大事情要发生似的。一瞬间这辆路虎飞快超过我们，也穿过了这只松鼠，一声清脆的咔嚓声传入我的耳膜，是那样的惊天动地，我看着松鼠在半空中翻了几圈又啪的一声掉在路上，就一动也不动，一点生息也没有了。顿时一种莫名的悲伤涌上了我的心头。为一个鲜活的生命逝去而痛心。

也许这个司机是无意的，没有看见松鼠。也许这只松鼠太相信人类了，认为大家都喜欢它，不会伤害它。可以惨剧确确实实在我眼前发生了，难道不能引起我们思考吗?

在我国青藏高原可可西里这个无人区里生活着许多藏羚羊，在修建天路时怕火车影响藏羚羊的迁徙，设计者们想出了在那里架设铁路桥，这样火车在上面过，藏羚羊从下面迁徙，人与自然在这里完美可以结合。这是保护稀有动物的极好例子啊!

在澳大利亚生活着许许多多的动物，动物在马路上走对于这里的人们不足为奇，司机们开车遇到动物还要主动给它们让路。这在当地是人们自觉的行为，体现了他们的爱心，所以在澳洲这块土地上才会有那么多的动物与人和睦相处。他们的行为难道不值得我们仿效吗?

现在的环境越来越好，动物朋友们会随时和我们邂逅。对于那些不期而遇的朋友，我们除了惊喜，当然还要注意保护它们。我们司机朋友在路上，不仅要避让行人，也要避保护它们，这也是我们社会文明社会进步的表现。

The boundless sea gives people the expectation, the beauty, the warm maternal love.

The sea is like a poem.Like a picture, the meaning is rich;Like a symphony, the vast...It is always calm, like a mirror;Now and then the rage, the surge of rage, can overturn the boat that sailed.In my mind, the sea is the blue world and the cradle of life.There are so many free and free lives.The sea is so mysterious, so charming!

Now the sea has changed.The water is no longer clear, its cloudy, its dirty.The water washed up on the sand, leaving no more of a bouncing fish, but a pile of trash, and a lot of shrill little shrimps.Why is that?Its all because of us.While enjoying the beauty of the sea, someone threw the stinky rubbish into the sea.There are also people living on the coast who make toilet discharge pipes to the bottom of the sea.Even worse, the waste water from the factory poured into the sea, and the water became a strange color.Lead to give birth to a lot of lack of brain ` low IQ baby, our next generation - the eyes bright ` voice immature ` gorge through red face the next generation will never see the beautiful blue sea.

Some people have done an experiment, he compared a basin of water to the sea, and drop a drop of ink into the "sea".At once, the ink spread slowly, shallower and disappeared, and the "sea water" was almost as clean as before.If the ink keeps dripping, "the color of the water will get darker and darker, and then it will turn into a basin of black water.The worlds six billion people produce a lot of waste water and industrial pollution every day, just as the ink has been pouring into the pristine waters of the sea, and the sea is now a pool of sewage.

For the sake of our human health, to see the beautiful and charming blue ocean for our children and grandchildren.Let us act immediately, love the sea as we love life, and love the common blue home of mankind.

同学们、老师们：

亲爱的全体同学：

野生动物是人类的朋友，是自然生态系统的重要组成部分，是大自然赋予人类的宝贵自然资源。保护野生动物，维护自然生态平衡，不仅关系到人类的生存与发展，也是衡量一个国家、一个民族、一个地区文明进步的重要标志。

我国是一个野生动物资源非常丰富的国家，但是由于生态环境的恶化，野生动物栖息地的人为破坏，致使我国野生动物的数量，分布范围正日益缩小，许多种类已处于濒临灭绝的状态。近几年，滥食野生动物的现象屡禁不止，使得许多已经处于濒临灭绝的野生动物的处境更加艰难。最近，有记者采访调查表明:很多地方滥食野生动物的现象还十分严重，滥食野生动物的行为也正受到越来越多人们的谴责，要彻底改变滥食野生动物这种不文明的行为，需要社会各界的共同努力。

为此，我们倡议:加大《中华人民共和国野生动物保护法》的普法力度，媒体和社会各有关部门，要进一步加强对保护野生动物的普法宣传教育工作，使《野生动物保护法》的宣传家喻户晓，深入人心。

我们倡议:保护野生动物是全社会共同的责任，林业、工商、卫生检疫、公安、交通等有关部门认真履行职责，相互配合。坚决打击非法盗猎、非法运输、非法经营野生动物的违法行为，全社会也要积极行动起来，举报并协助执法部门，坚决与各种破坏野生动物的违法行为作斗争。

我们倡议:为了保护生态环境、为了保护野生动物资源、为了我们的身心健康，不食野生动物，树立饮食新观念，摒弃不良饮食陋习，保护野生动物从餐桌做起。争做文明、守法、有爱心的公民。

朋友们，为了人类共同的生存环境，让我们共同努力，一起行动起来，从我做起，从小事做起，让大地处处充满生命的绿色，让野生动物与我们在同一片蓝天下平安地生活。

让我们携手共创21世纪人类与野生动物和谐共存的美好家园!

保护野生动物就是保护人类自己。由于坏境的恶化，人类的乱捕滥猎，各种野生动物的生存正在面临着各种各样的威胁。近100年来，物种灭绝的速度已超过了自然灭绝速度的100倍，现在每天100多种生物从地球上消失。我国也已经有10多种哺乳类动物灭绝，还有20多种珍稀动物面临灭绝。而它们的灭绝会导致用于制造新药分子归于消失，还会导致许多有助于农作物战胜恶劣气候的基因归于消失，甚至引起新的瘟疫。由此所造成的损失是我们永远也无法挽回的。

《中华人民共和国野生动物保护法》规定珍贵、濒危的陆生、水生野生动物和有益的或者有重要经济、科学研究价值的陆生野生动物受国家法律保护，所以滥食野生动物是违法行为。

国家一级重点保护野生动物有96个种或种类，如大熊猫、金丝猴、中华鲟等。国家二级重点保护野生动物有160个种或种类、如猕猴、黑熊、金猫、黄羊等。

但是，人类猎杀野生动物的现象还在不断发生。有些人杀了大象，把大象的象牙给拿下来，做成象牙制品，赚取高额利润;有些人猎杀老虎，把老虎的虎皮的刨了下来，做成虎皮地毯，老虎的骨骼泡虎骨酒;有些人猎杀藏羚羊，用它的毛皮做围巾;还有些人猎杀动物做美餐……正是由于人类毫无顾忌地大量猎杀野生动物，才导致不少的野生动物灭绝和濒临灭绝。

动物和我们人类一样，也是这个地球上的一份子，如果我们不计后果，继续乱捕滥猎，将会引来新得灾难，2003年的非典病毒流行，不就是一个典型的事例吗?所以，我们应该立即行动起来，禁止猎杀野生动物，保护它们，让他们和我们人类同在一片蓝天下和睦相处吧。最后，我要大声呼吁：保护野生动物，人人有责!

Boundless sea to look forward to, give people the beauty, give a person warm motherly love.

The sea is like a poem; it jumps; like a picture, rich in meaning; and like a symphony, vast and mighty...... It is like a mirror; sometimes calm, sometimes filled with rage, overwhelming, to sail the boat overturned. In my mind, the sea is blue world, is also the cradle of life. Pregnant with many free and small life. The sea is so mysterious, so charming!

Now the sea has changed. The sea is no longer clear, it becomes muddy and dirty. Washed up on the beach, left is no longer alive and kicking the fish shrimp, instead of the piles of rubbish, but also mixed with a lot of dead fish shrimp, stinking. Why is that? Its all because of us. When people admire the beauty of the seaside, they throw the foul rubbish into the sea. There are also people living on the beach, the toilet drain pipe to the bottom of the sea. Whats worse is that the factory waste water flows into the sea in large stocks, and the sea is dyed in a strange color. Led to the birth of a lot of lack of brains, low IQ infants, our next generation - bright eyes [voice tender], the face of the next generation of red, will never see the beautiful blue sea.

Someone once did an experiment. He compared a basin of water to the ocean, and dropped a drop of ink into the sea. Immediately, the ink slowly spread out, became shallow and disappeared. The sea water was almost as clean as ever. If the ink kept dropping, the color of the sea would be deeper and darker, and eventually it would become a basin of black water. 6 billion people on the earth produce large quantities of living waste water and industrial pollution every day. Like ink, it has been injected into the clear sea water. It has become a polluted lake.

To the health of our human beings, to see the beautiful blue sea for our children and grandchildren. Let us act now, love the ocean as much as we love life, and love the common blue home of mankind.

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。

Animals Need Protecting

Earths biological diversity is being fast decline of many species facing extinction. Threat to the survival of wild animals and plants is a major factor in habitat loss, business development, and wild animals and plants and their products in international trade. Resources are limited, it is necessary for the endangered species, to propose specific measures of protection level. We can formulate the corresponding endangered species laws, application to establish nature reserves, endangered species breeding centers, means of conservation biology, endangered species, the implementation of in situ conservation and ex situ conservation. At the same time, we must restrict international trade in Endangered Species of Wild Fauna and Flora, to make laws to protect endangered species.

“我想回家，我想找妈妈……”一阵阵声音从教室里传出来，原来这是小鱼的呼唤。如果让你关在屋子里不出去，你会不会感到不快乐？鱼儿也一样！

在今天的教室里，多了几条活泼可爱的小鱼，看着它们在鱼缸里转来转去，一个声音从我的心中传出：“让小鱼儿回家吧，让它得到属于自己的自由！”于是，我们在老师的带领下，准备去放生小鱼。

走在山间的小路上，我不由得心想：我是多么依依不舍呀！我抱着鱼缸不敢走得太快，怕鱼儿在鱼缸里会动荡不安，可又怕走得太慢会让它在水中的伙伴等得太久。我们好不容易走到了盘龙山脚下，啊，这里山清水秀，鸟语花香，真的让人流连忘返！

我们来到池塘边，池塘里的水清澈见底，碧波荡漾，不时有黑色的小蝌蚪在水中自由自在地游着，好不快活！

准备放生了，我们小心翼翼地将小鱼倒入水中，那一刻，我是多么地不舍呀！小鱼在水里游来游去，像是在感谢我们，又像在和我们告别……可我硬是转身离开了，心里异常沉重。回去的路上我看到路旁的小草在向我点头，玉兰树似乎在向我点赞。我的心情也逐渐好转了，因为我知道我今天做了一件令自己都敬佩的事！

“劝君莫食三月鲫，万千鱼仔在腹中。”我们一定要保护动物，让所有的动物朋友都能得到属于自己的自由和快乐！

在一片天空里，候鸟在飞着，它飞过了崇山峻岭，飞进了属于自己的世界。可是为甚麽人类打破了这个美丽的世界，打破了鸟儿的自由。

当它被人类捉起来的时候，他是多么希望有那麽一个人可以伸出援手来帮助他，解开他身上的铁锁，让他重新飞回天空。

可是谁会这样做呢?谁会不想吃美味的烤鸟啊，可是我们儿童不会，因为一个小生命在你手中，难道你会忍心看着它被别人煮来吃吗?

我想世界的每一个动物都想拥有自由，不会想眼睁睁的看着，自己被别人吃掉，所以它们飞向自己向往的地方。

我看到鸟儿们都在欢笑，他们喜欢在这片天空下飞翔，无论经过多少的风雨，他们也不害怕，因为天空是他们的飞翔的翅膀，他们带着希望，与其他的鸟儿，一起飞过一座座城市，看到了世界的美好，感受了飞翔的美丽，和那些经历过的酸甜苦辣，风风雨雨。他们飞了3100英里。你说在那段时间里，他们有过被别人爱护，也有过被别人本想捉起来的人。

啊!看，人们正在保护大自然，原来他们在保护每一个动物，不让他们灭绝，不让人们都看不到它的影子，不让它成为历史。每个人都在环保，把自己的垃圾放进垃圾桶，每年植物节都来种树，给动物们更多的家，更多的空间。

人类与动物让它们团结不是更好吗?让他们成为人类的好朋友，知心朋友，在你烦恼时让动物给你增添快乐，有时你们去草地玩耍，不停的奔跑，把什麽都忘掉，只顾着奔跑。

我们的好朋友永远都是动物们，无论是多麽凶险的动物，它们也是我们的好朋友，我们不会忘记，你们是我们永远的好朋友，是我们永远的希望。

"Green" the eternal topic, let us better to understand the importance of environmental protection.

Green environmental protection is to make us live a happy life in a clean environment, however, the environment around us in a worse if we dont alarm, then, our motherland will be a mess in our hands! Green environmental protection starts from me. My dad used to drive his car to work, listen to my advice, to protect the environment, he ride a bike from now on, he thought that not only the exercise of his body, also for the green environmental protection.

My mother began to contribute to the green environmental protection. Before she went to vegetable market to buy food, she used plastic bags, a village green environmental protection propaganda on TV, she understood the green environmental protection is sustainable, in order to we can have a better environment. In order to we live healthier lives, so mom from that moment on, every day go to vegetable market with the own basket, instead of plastic bags.

As a new era of junior middle school students, and I will response to the green environmental protection call for, I had at school are all use one-off chopsticks, but now I can bring their own chopsticks to school. I think, though this is a small matter, but I do my responsibility.

Happiness of life to let China land everyone be permeated with happy smile, rich products, long history, noble quality, the plot environment. Nowadays, the environment is polluted, the green environmental protection starts from me, let us together to protect the environment!

Now, the earths environment continued to deteriorate, give people brought a lot of disaster, all this comes from peoples pollution. Want to let her to reduce pollution, only environmental protection.

Life, environmental protection is everywhere, such as: saving water, use less plastic bags, use of solar energy, hydroelectric power. Promote environmental protection and more people, has said that the earth is crying, please protect the environment. Also have said that protecting the environment, everyone duty, various and diverse. But some people dont cherish the earth, the stubborn still: waste paper, waste water, drive a car.

Once, I saw a man in the street in the smoke, smoke after not even cigarette out, throw it on the ground. Then he began to eat melon seeds, casually eat shell to vomit. I cant see it, he said to him: "how could that happen?" He said: "a child, understand what ah, go away. I have no fear, for he said:" I though small, but I also know that this is wrong, and you are an adult! And you also throw cigarette butts on the ground directly, now the weather is dry, one thousand fires to do. "Paused and said," there are sunflower seeds, the somebody else see how to think, you are affect the environment. "The man looked down, without a word, I think he will be corrected.

Another time, I went to my cousin home, saw the water as he scrubbed his hands on loud, wash your hands after he hands with a lot of paper. After I watched the said to him, "why are you so wasted?" Upon hearing this, he pursed mouth said to me: "so a bit, and has nothing to do!" I said angrily: "this has nothing to do how? Do you know those impoverished mountainous area children how much water one day only drink? Know not to know how much they only paper?" But my cousin drive is rightfully said: "dont know!" I said with a sigh: "we are more happy than them, how dont you know contentment?" At this moment, my cousin know "importance" of the story, low head, said: "I know I was wrong, Ill correct."

Let us start from me, to protect our only home!!!!

现在，地球环境持续恶化，给人们带来了许多灾难，这一切都来自人们的污染。想要让她减少污染，只有环保。

生活里，环保随处可见，比如：节约水资源，少用塑料袋，利用太阳能、水力发电。宣传环保的人也多了，有说地球在哭泣，请保护环境的;也有说保护环境，人人有责的，各种各样，五花八门。但也有人不爱惜地球，依旧我行我素：浪费纸张，浪费水资源，开汽车。

一次，我在街头看见一个人在抽烟，抽完后连烟头也不灭，直接扔在了地上。接着，他又开始吃瓜子，吃完的壳随便一吐。我实在看不下去，就对他说：“怎么能这样呢?”他说：“一个小孩子，懂什么呀，走开。我没有害怕，对他说：“我虽然小，但也知道这样不对，何况你大人!而且你还直接把烟头扔在地上，万一现在天气干燥，引起火灾怎么办。”停了停，说，“还有瓜子壳，人家看了怎么想啊，你这是在影响环境。”那人低下头，没有说话，我想他会改正的。

还有一次，我到堂弟家做客，看见他洗手时把水开得很大，洗完手后他还用很多纸擦手。我看了后对他说：“你怎么这么浪费呀?”他听后，撅着嘴对我说：“就这么一点，又没什么关系!”我生气地说：“这怎么会没关系呢?你知不知道那些贫困山区的孩子们一天只喝多少水?知不知道他们只有多少纸?”可我那不服输的堂弟却理直气壮地说：“不知道!”我叹了口气说：“我们比他们要幸福多了，你怎么不知道知足呢?”这时，堂弟知道了事情的“重要性”，低着头说：“我知道错了，我会改正的。”

让我们从我做起，保护我们唯一的大家园吧!

I went to the gate of the primary school in shangjia city, and I was like walking into my other home, where I studied, lived, grew up, and my school was my home.

Lush trees, clean corridors, white walls. However, there are a few students on our campus who break the beautiful environment at will. The campus stairs and the various food packaging bags in the hallway, the various drink bottles of the flowers, the prunes in the classroom, the melon seed shells... The environment that makes us beautiful is destroyed, and it feels like a blank sheet of white paper. Taking care of the campus environment is the duty and responsibility of each of us.

So what can we do to make our campus environment civilized?

To set up the campus is the idea of home, the campus is my home, everyone loves it. Students should love the campus as much as they love their new clothes.

On the campus, the behavior should be standardized, from the little things, from a little bit, the daily behavior standard is every day, every time, everywhere.

We will comply with the regulations of the elementary school childrens daily behavior and strictly observe the institutions of the school. Be a good boy at home, be a good student at school, and be a civilized citizen in society.

4, do not break the environment of the school carelessly, should not throw waste to the ground; You shouldnt leave a mark or a handprint on a white wall. Consciously pick up every piece of paper or food bag on the floor; Stop unethical behavior.

To correct bad behavior, we cant just rely on our teachers and consciousness. Use concrete actions to protect and protect our campus environment. Start by myself, start by yourself, start every day, protect the campus environment.

With big eyes， there is an emergency ears like flying up to now。 You guess what？ Let me guess， is the rabbit。

A rabbits eyes like ruby， of course， I also gave a name to my rabbit called ruby。 Because the rabbit eyes glistened like ruby。

Remember once， my mother took me to go for a walk， I bring my ruby went to the park。 Ruby remembered it home for many years， because of the ruby grew up in the park， but his mom and dad have vanished into thin air， I also know that the rabbit is very poor， but I also didnt find its relatives。 The rabbit ears soon ran off， may be sad， I had to chase her for a long time。

This is my favorite little animals。 Smart， lovely ruby。

眼睛大大的，有紧急情况耳朵像飞的一样竖起来了。大家猜猜是什么？猜不到吧，就是兔子。

兔子的眼睛像红宝石一样，当然，我也给我的兔子起了一个名字叫红宝石。因为兔子的眼睛像红宝石一样亮晶晶的。

记得有一次，妈妈带我去散步，我带着我的红宝石来到了公园。红宝石想起了它多年的家，由于红宝石是在公园里长大的，但是他的爸爸妈妈却消失得无影无踪，我也知道兔子很可怜，但是我也没有找到它的亲人。兔子很快就竖起耳朵跑了起来，可能是伤心了，我追了很久才追到。

这就是我最喜欢的小动物。聪明、可爱的红宝石。

Dear Lily:

I think you had better feed a hamster,the trediest kind of pet these days is the small hamster. People like them because they are quiet and clean. I have a hamster named Tom,it’s very cute and easy to take care of,and it’s cheaper than rabbits or cats,so I bought it. She’s my best company,because she reads books and litens to music with me every night.However,life with a hamster isn’t always perfect,she sometimes noisy at night ,she love sleep all day,too. So,sometimes she is very boring! How do you think?

从古自今，世界上的动物种类非常多，但绝种的动物也不计其数。根据生物学家估计，经几千年来，被人类杀害导致绝种的动物，至少有数百种以上。如此一来，世界上的动物就会越来越少了，如果我们在不及时挽救的话，那么将来世界上的动物，可能就只剩下人类了。

大自然是悠久的，富饶的，它拥有的野生动物，是留给人类的无价之宝，如何安抚饱受欺凌的野生动物，就是我们保护动物的基本观念。对动物而言，滥杀是最可怕的行为，然而他们所面对的大敌---猎人，却为了满足自己的口福之欲，或是为了换取钱财，而对他们大肆捕杀。估计在过去的五年之内，有两万只东非的猫科动物被捕杀。每制成一件薄皮大衣就需要十二张动物的毛皮，这些毛皮大衣真是供不应求，价格也非常昂贵。因此必须严禁盗猎者滥杀，违者可以用罚款和判刑来处置。我们身边也有不少虐待动物的例子;班上有些同学会掏鸟窝、杀青蛙，还把小蛇带到学校，吓得一些女生一边尖叫一边用手捂着脸。还有些男生把小蛇杀死后用绳子扣住它尾巴到处吓人。

在动物园里，有些人会经常喂动物吃东西，有些动物不知道怎么吃，往往连塑料袋也了下去，这样一来，再多的动物也会被这种举动折磨死.饲养员们应该多教些喂养知识。这也是爱护动物的有效办法之一。总之，现在我们必须积极保护动物，以免再有动物绝种。试想;如果我们的子孙不能见到大自然的宝贵珍品，那将会是多么遗憾哪!所以保护动物的政策要坚决实施，使野生动物不再灭绝，甚至培植一些新的种类，使我们的子孙也能在观看动物时，享受到我们曾有过的乐趣。

保护动物从我做起!从现在做起!

[保护动物的高中作文900字

A triple bacon cheeseburger seems like a heart attack on a plate.

三层奶酪咸肉汉堡感觉吃完很容易让人突发心脏病。

So how can polar bears thrive on their version, seal blubber?

那么,北极熊是如何处理这些高热量食物的呢?

Turns out theyve stocked up on genes that let them clear fats from their blood.

结果显示它们储存在遗传基因里的信息使得它们能够清除血脂。

Thats according to a study in the journal Cell.

这是根据《细胞》杂志上的一篇研究得出的结论。

Polar bears are well adapted to life on the sea ice.

北极熊非常适应在浮冰上的生活。

Up to half their body weights fat, which gives them extra insulation and buoyancy, and provides them with a ready source of energy.

几乎占它们身重一半的脂肪足以使它们保暖并且维持体力，提供给它们一种易转化的能量。

But how can an animal so fat also be so fit?

但一种动物怎么能又胖又健康?

Researchers compared the genomes of polar bears with those of brown bears, and found that polar bears have accumulated genetic changes that boost their heart health and fat metabolism.

研究人员们通过比较北极熊和棕熊的基因，发现北极熊的基因组中积累了不少有利于心脏健康和脂肪代谢的遗传突变。

One gene in particular, called ApoB, helps move cholesterol out of the blood—where it causes problems in humans—and into cells.

特别是编码为载脂蛋白B的基因有助于清除血液中对人类有害的胆固醇转变成细胞代谢。

These genomic changes happened quickly, evolutionarily speaking.

这些遗传变化从进化的角度来讲发生的十分快。

Polar bears and brown bears diverged from a common ancestor less than half a million years ago.

北极熊和棕熊都来自于同一个祖先，它们是在大约50万年前左右开始向不同分支进化。

But if that seems super speedy, the ability to digest lactose didnt spread through human populations until we domesticated cows, just 10,000 years ago.

但是如果这种变化看上去十分快速的话，消化乳糖的酶逐渐进化到人类各个种群中也还是发生在大概1万年前我们可以驯化乳牛之后。

A moooving testament to the power of natural selection.

这是自然选择力量的证明。

“保护动物”这四个字我们每天都在说，可是又有多少人在用实际行动表示呢?被割掉胸鳍和尾鳍的鲨鱼，被割掉角的犀牛，用洁白的象牙制作的装饰品，活熊取胆……这一件件残忍的事情时常发生，申赋渔的《逝者如渡渡》叙说了数百年间，世界各地灭绝了的或正在走向灭绝的30多种动物的故事，如：日本象.指猴.象龟.渡渡鸟……它们都是人类的伙伴，它们也曾快乐的生活在这个地球上，可是，因为人类掠夺了它们的生存空间，使它们从地球上永远消失了。

全球变暖，使北极熊赖以生存的浮冰断裂.消融。也使他们的食物——海象.海豹逐渐减少，使北极熊频临灭绝;人口迅速膨胀和乱砍乱伐，使熊猫的生存范围被迫向竹子稀少的山顶推进，食不果腹成了家常便饭，当竹子开花时，有些野生熊猫会因找不到食物而饿死。熊猫虽是我国的“国宝”，可在全世界的数量也不过区区2000多只。

人类啊!醒悟吧，让“保护动物”不只是说说而已。动物是人类的朋友，是地球大家庭中的一员，动物同人类生活在同一个地球上，动物作为食物链中的一员，如果动物灭绝了，那么人类也逃脱不了灭绝的厄运。

动物是有灵性的，它们也有思维和感情，人类怎么能忍心去杀害它们呢?每一个物种的消失，都是人类走向孤独的脚步，没有了动物的陪伴，人类还能走多远?保护动物绝不仅仅是一个组织的责任，大自然为大家所共有，保护动物，人人有责。但愿每个人都问一下自己，自己的行为曾经给地球带来过怎样的伤痛?自己有没有为一时的利益而透支我们的未来?

Dear headmasters,teachers,classmates and friends:
