如何写保护动物的英语作文（20篇）

Low-carbon life means a kind of lifestyle in which people do their best to reduce energy consumption and carbon dioxide emissions.

Then，how can we live a lowcarbon life?Firstly，we should recognize that the lowcarbon life is not only a kind of lifestyle but also a life attitude.Each of us is responsible for the greenhouse gases in our daily actions.To combat climate change we have to take the combined efforts of everyone on the planet.Secondly，we should develop good habits in our daily life.Paper cups are made from cutting forests.We should try not to use them because trees can absorb carbon dioxide and reduce greenhouse gases.Similarly，lights should be turned off when they are not used，which will greatly reduce electricity consumption.

In a word，small actions above can make a big difference.

寒假里，爸爸、妈妈带着我来到了杭州动物园。那里我去过好多次，但这次并不像以前一样兴奋。以前看到奔跑的骏马，上窜下跳的猴子，以为它们过得很快活。那天，我却看到它们伤心和无奈的样子。在这酷暑里，马儿不知要为多少游客服务，它们疲惫地耷拉着脑袋。上窜下跳的猴子被训练员鞭打，很可怜的样子!

走着走着，我又看到很多小动物被关在笼子里，像小鸟、小兔、小狗都关在很小，很湿的地方，小鸟“叽叽喳喳”地叫着，好像在说：“我又不是犯人，干嘛把我关起来，生活在比监狱还差的地方，真是太不公平了!”小兔“吱吱”地叫，好像在说：“救救我，我不想生活在这样的地方!”小狗“汪汪”地叫，好像在说：“你们还说动物是人类的朋友，对待朋友是这样子的吗?”

我们来到了黑熊住的地方，很多游客都不停往里面扔东西，根本没有注意旁边的警告牌“勿扔食品!”管理员告诉他们不要这么做，他们不听劝告，继续往里扔东西。在报纸上曾经报告过一个大学生为了做实验竟然把硫酸泼在一只黑熊身上，使它痛苦地倒下了，身受重伤。为什么那位大哥哥会这样残忍?难道他没有想过这样黑熊会很痛苦吗?

人们常说：“动物是人类的朋友。”对待朋友是这样的吗?对待朋友要像对待自己一样，这样才公平。动物是人类朋友，我们就该保护动物，善待朋友。

Everyday, they play with each other happily. One day, I couldn’t find them. I asked my mother: ”Where are they? ” My mother told me that She didn’t know. At last, I found them in the grass.

你热爱动物吗?动物和人类一样都是我们这个美丽星球的拥有者，都有权利在这个星球上自由的生存，都有权利享有大自然赋予我们的一切，这是我们共同的家园。然而在有些人眼中，这些动物不过是一些任人宰割、没有生命、没有感情的东西。它们不过是餐桌上的美味或能换取金钱的物品，人们为了皮衣和食品杀死各种飞禽走兽，为了所谓“口福”大量捕杀贩卖山珍野味，满山的捕鸟网，遍野的捕兽套，令人触目惊心的动物残骸，诸如此类的报道屡见不鲜，不绝于声。致使动物种类大幅减少，有些动物已经灭绝或濒于灭绝，太残忍了。

不知道那些人长的是怎样的铁石心肠，如果任其发展下去，我们再也听不到百鸟争鸣，再看不到鱼翔海底，许多动物将成为“据史料记载”。这个世界将不再丰富多彩，这个世界将只剩下贪婪人类的孤独和凄凉。这是整个人类的悲哀。

有一句话说的好，保护动物就等于爱护我们自己，大自然中的任何一种动物都是食物链的一环，一环不可缺少，缺少任何一环都会打乱自然界的平衡，遭殃的还是我们自己，许多动物都是人类的朋友，人类自己不是经常把动物分为益虫和害虫吗?

如果益虫都灭绝了，那会是怎样一种情况呢?如果害虫灭绝益虫也不复存在，动物的生存灭绝与我们的生活密切相关。保护动物，珍惜生命，是我们从心底发出的呼唤。我们要从身边的小事做起，爱护小动物，爱护弱小生命，拒绝食用野生动物，拒绝穿戴使用兽皮、兽骨做的衣服，饰品和用品。坚决抵制残害动物的行为，为我们和动物共同营造一个和谐共存的家园。

亲爱的市民朋友们：

四、人人行动起来，积极劝说阻止、举报各类破坏森林、伤害野生动物的行为，做保护生态环境的模范。

让我们携起手来共同努力，把广州建设成为处处鸟语花香、人与自然和谐的美丽花城!

These days, different ways are being taken to protect cultural identity. Obviously, not only is much contribution made to maintain old houses but also rules of laws associated with cultural protection are changed for the better. Some people even say that new buildings are right to be set up in the conventionalway. I seem to be one of opponents who believe that the action can be unsuitable in our world.

One of the main reasons is that most of traditional buildings, in my nation, that offer provide few rooms can hardly hard to meet the demands for housing as increasing numbers of people pour into the city. Compared to before, todays population has doubled and even trebled, which puts seriouspressure on housing supply. As a result, new buildings must be substituted for old ones that have more efficient utility, even for some old buildings that have been damaged seriously.

No doubts that building or maintaining traditional buildings is very essential to raise art sense and increase choices of peoples housing. Plus, these old houses are believed as very important resources to attract international visitors. However, the proportionof traditional houses has to be under control, and otherwise the housing of citizens is badly affected.

Overall, my view is that cultural identity is so preciousthat more efforts and measures should be taken but carefully. The excellent tradition helps with deep understanding of history, and educates youths. Nevertheless a simple and recklessbehavior. that new buildings are built in a typical way does more harm than good in the improvement of peoples being.

随着人们生活水平的逐渐提高，对生活用品的要求也越来越高。一些工厂为了自己的利益，把排出的废水倒进清澈的小溪里;把废气排进森林里。森林渐渐枯萎，小溪渐渐污浊，一些动物和人类因为喝不少不干不净的水而死去，这已经危害到了我们的生活环境!现在，一片片森林逐渐减少，一座座工厂在逐渐增加;绿色在逐渐减少，灰色在逐渐增加。人们只顾及自己的利益，完全不管坏境。醒醒吧!赶快行动起来保护环境吧!

at work, people use water to put out fires, to grow vegetables, to make things in factories and so on. we also can swim in the sea.

water is important for us, isn’t it?

.There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities. To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources

and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves

Snakes蛇

The snake is a long and thin animal that lives in grass or other dark places. A snake has no legs or feet, but it can move very fast on its stomach. Snakes usually have green, yellow or black skins, which make them difficult for their enemies to find them.Some kinds of snakes live in water. They can swim as freely as fish.

蛇是一种又长又瘦的动物，生活在草丛里和阴暗的地方、蛇没有腿和脚，靠胃部飞快的移动前进。 蛇常常有绿色，黄色和黑色的皮肤，使得敌人很难找到他们。

Snakes are cold-blooded animals. In winter they hibernatein holes which are narrow enough only to hold the snakes bodies. The snakes can sleep through a whole winter without eating and moving. They can not feel any pain. The hibernation period lasts about five months. When spring comes, the snakes come out and begin their normal life.

蛇是冷血动物，在冬天，它们通常隐藏在只能容下它们身体的狭小的小洞里。蛇可以不吃东西，不移动地睡一整个冬天。它们不会感觉到痛苦，它们的隐藏时期持续大概5个月。当春天来临的时候，蛇就会出现并开始它们的正常活动。

Snakes can take many things as food, such as mice, sparrows, frogs,birds eggs, pests and so on. People sometimes can see a snake eat a sparrow. First it moves close to the sparrow, then it puts out its tongue and brings the sparrow into its mouth and swallows it, which makes a lump in the snakes body. After some time the lump disappears.

许多东西都可以成为蛇的食物，就像老鼠，麻雀，青蛙，鸟蛋和害虫等等。人们常常看见蛇吃麻雀，蛇首先靠近麻雀，然后伸出它的舌头把麻雀带进它的嘴巴里并吞下去。麻雀就像一块肿瘤一样突出在蛇的身体里，但是过了一段时间就会被消化消失。

As snakes are dreadful-looking, people are afraid of them. Many people drive them away whenever they see snakes. But in Chinese fairy tales, snakes are by no means bad. They seem to have human feelings. They can change into pretty girls. People like and respect them. The most well-known is the story about the White Snake and the Blue Snake.

因为蛇看起来很可怕，所以人们总是害怕它们，很多人每当看到蛇的时候都会把它们赶走。但是，在中国的神话故事里，蛇并不代表坏人，它们可以感觉到人类的想法，它们会变成美丽的女生，人们喜欢和尊重它们。最著名的故事就是白蛇与青蛇的故事了。

In fact, snakes are not as dreadful as they look. They can help us to kill mice and pests. They can provide us with delicious meat. Their blood is a good drink. Poisonous snakes are especially useful. We can make valuable drugs with them.

事实上，蛇并不是像它的样子那么可怕，它们可以帮助我们杀死老鼠和害虫，它们可以给我们做成美味的佳肴，它们的血是很好的饮料。毒蛇就特别有用处了，我们可用它们做成珍贵的药品。

Dear editor,

I know on your school English newspaper that the readers are expected to have a discussion on the topic of protecting Traditional Chinese Culture. The protection of national and folk culture is of great significance to Chinese cultural diversity and also to the harmonious social development. I have a strong desire to share my personal viewpoints on it.

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

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

关于保护动物高中英语作文1：Animals Need Protecting

Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people care? Because we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

I am a student from Xinhua High School in Chongqing，China. Informed that you have a vacancy for a student to serve as the spokesman for animals, I cannot resist my inner excitement,hoping to seize the opportunity to do something for animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I go and whatever I do, I usually keep in mind that animals are angels from the heaven, which bring us endless comfort and pleasure. I have been a panda lover since my childhood. Panda is so lovely that brings fun to people and they are regarded as the treasure of our country. Unfortunately，such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies.

关于保护动物高中英语作文3：How tu protect animals

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

Through observation, I found that plastic bags on peoples harm and pollution is very large. People often use plastic bags: mother to buy food and plastic bags; to shopping malls with plastic bags; in the restaurant to eat rice is also packaged with plastic bags to take home; even I buy stationery also with plastic bags. People do not know what they do to the environment caused by pollution, their own body caused any harm. Such as: people often put useless plastic bags thrown into the garbage, plastic bags in the rubbish will be smelly, so that the pollution of the air. People also throw plastic bags anywhere, a wind, plastic bags flying in the sky, the branches also see the tree is a plastic bag, and even the river there are plastic bags. This plastic bag in addition to pollution of the air, but also polluted our water resources.

We should raise peoples awareness, tell us the neighbors and friends and family together to beautify our environment. On the road to see the plastic bag quickly picked up, immediately took it to the garbage disposal. We want to start from my use less plastic bags, so that my mother every day to buy food or shopping when they first take their own bags, this is not very environmentally friendly? Or can use their own holding things as far as possible by hand, no plastic bags.

As the saying goes: "to protect the environment, everyone is responsible" We have to protect the home environment out of a force.

[关于保护环境的英语主题作文

Some people think that human needs for farmland, housing, and industry are more important that saving land for endangered animals.

Do you agree or disagree with this point of view? Why or why not?

Use specific reasons and examples to support your answer.

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is “Yes.”

Yes. It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will effect all the other parts.

For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.

Yes. Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies, which migrate from Canada to Mexico.

Some of the breeding grounds of these butterflies were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.

Yes. The quality of our life has been changed America used to be covered with giant trees. Now we have to visit them in one small park.

Rain forests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.

I would encourage us humans to look for other alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

Do you know what kind of animal I like most? It’s monkey. Monkey is a kind of lovely animal.

Many people like monkeys very much. Generally, monkey has small body covered with fur. Some kinds of monkeys have two big eyes and ears and a long tail. I can see them on TV or the zoo.

Every time I go to the zoo, I will go to see them.

Monkeys often stay in trees and jump between them. They are so lively and favorable. When they are happy, they will act for visitors. It’s very funny.

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。
