Do you love animals? Animals and human beings are the owner of this beautiful planet that we all have the right to freedom of survival on this planet, have the right to enjoy nature gives us everything, this is our common homeland.

However, in the eyes of some people, but these animals is some lose your life, no life, no feelings. They are just delicious or money can buy the things on the table, the people in order to kill all kinds of animals and birds, fur clothing and food in order to the so-called "mouth" a lot of killing selling duck, full mountain bird nets, traps set, overrun by shocking animal remains, such as there are numerous unsubstantiated reports that have appeared. Dropped sharply in animal species, some animals have become extinct or endangered, too cruel. Dont know what those people long is the heart of stone, if left unchecked, we can no longer hear birds schools of thought contend, and cant see the fish live the bottom of the sea, many animals will become "according to historical records". The world will no longer be rich and colorful, the world will only greedy human lonely and sad. This is the tragedy of the entire human race.

Have a word said good, protect animals is to love ourselves, any kind of animal in nature are one part of the food chain, a ring is indispensable, the lack of any one ring will upset the balance of nature, to suffer or ourselves, many animals are friends of human beings, human beings are not often divides into the animal beneficial insects and pests? If beneficial insects is destroyed, it is how a situation? If extinction beneficial insects pests also ceased to exist, the survival of the animal extinction is closely related to our life.

To protect animals, cherish life, is that we call, from the bottom of his heart. We should start from around things, care for small animals, care for the weak life, refuse to eat wild animals, refused to wear clothes made of animal skins, animal bones, accessories and supplies. Resolutely resist the behavior of animal cruelty, and animals together for us to build a harmonious coexistence of their homes.

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。

[水英语作文

We are paying more attention on many environmental problems we made before, one of them is the water emergence. Long time ago, we never noticed that we are in a situation that the water on the earth is less than before, and the consequence is continuing.

Until recently, we have started to acknowledge that we should make the bigger efforts to save water. Therefore, so save water from every single person is important. That is why we should save water at home. If every one of us saves water at home, then the water saved together would be a huge amout. And I have some suggestions following: we could cycle the water we just used them to wash clothes to water the plants or to rush the toilet; when we wash our hands, we could turn the tap off for the moment we put soap on our hands etc.

So if we want to save water sincerely, we could save it at home .

How to protect the environment.

Good environment can make people feel happy and fit . To improve the environment means to improve our life.

We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.

Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.

[提倡保护环境的英语作文

Chinahas a very long and brilliant history, whose people are so friendly

and hospitable. But I am wondering why some people pay such little attention to

the environment and nature. In many places of the countryside, rivers have

become stinking sewers and brooks have disappeared. Heaps of garbage obstructs

the scarce flow of dirty water. The grounds are littered with plastic bottles

and bags. People are cutting down trees even though it is illegal. In some

towns, rubbish is hidden behind walls. Garbage cans are often of little use,

making cleaners must rush all day long and also by night to clean the

rubbish.

This lack of consideration for nature in general is extremely detrimental

to children’s education, toChina’s image, to public health, to tourism and to

the future.Chinais the common treasure of all Chinese, and we should live up to

be a member of this big family, a descendant of 5000-year-plus ancient civilized

country. I think the environment must absolutely be strictly protected by all

means. This protection should go at the same pace as the marvelous development

of the nation.

In this respect,Germanyis a rare model and leaves me a very deep

impression. After you have an exciting tour around in this country for a week or

so, it is unnecessary for you to polish your leather shoes. Personally, first of

all, the strong awareness of people’s environmental protection; then, the

advanced technology applied in the field of preserving the nature; We can learn

form others in building China into one of the most environmentally friendly

places in the world.

The earth is our home, the environment is closely related to our life. Humans consume enormous amounts of water resources and environmental pollution, have a beautiful earth destroyed not decent. Water gradually less, plants and animals endangered... All this because human dont pay attention to protecting the environment.

People cut down trees everywhere, and now the world average cut 11 million hectares of forest a year, this is such a big number! People with throw garbage, the floating on the river stinking garbage, the dirty plastic bags hung on the branches, the dark skin and confetti were piled on the grass. Have done great damage to environment, river, forest green, blue sky has disappeared, the earth is destroyed gradually, humans also gradually die.

Originally, the earth has a clear brook, green forest, the blue sky. Ancient times, how many poets praising the earth beautiful environment! Human is maker of environmental disaster and environmental disaster victims, more should be an environmental disaster prevention. We have to start from oneself, start small, join hands to jointly protect the environment, protect our homeland. For our children leave water, forest, the blue sky.

Lets joint efforts in order to better tomorrow!

地球是我们的家园，环境与我们的生活息息相关。人类大量的消耗水资源和污染环境，已经把一个美丽的地球毁的不象样了。水渐渐少了，动植物濒临灭绝……这一切都是因为人类不注意保护环境造成的。

人们到处砍伐树木，现在全世界平均一年砍掉1100万公顷森林，这是一个多么大的数字啊!人们还随手丢垃圾，那发臭的河面上漂浮着垃圾、那肮脏的树枝上挂着塑料袋、那黑黑的草地上堆着果皮和纸屑。环境遭到了很大的破坏，清清的小河、绿绿的森林、蓝蓝的天空都消失的无影无踪了，地球渐渐被毁灭，人类也渐渐死亡。

原来，地球有着清澈的小河，绿绿的森林，蓝蓝的天空。古代，有多少诗人赞美过地球美丽的环境啊!人类既是环境灾难的制造者，也是环境灾难的受害者，更应是环境灾难的预防者。我们要从自己做起，从小做起，携起手来，共同保护环境，保护我们的家园。为我们的孩子们留下碧水、森林、蓝天。

让我们为了美好的明天共同努力吧!

Many animals are in danger of dying out. As is shown in the chart, we can see the number of animal species decreases faster and faster and this trend will continue. From 1980 to 2010, at least 1 million animal species have disappeared. Worse still, more and more wild animals are in great danger. It is not a piece of sensational news; it is a fact, a harsh reality. Unfortunately, we may not see these animals in the near future.

From the second picture, we can find some reasons. Why is the number of animal species declining year by year? Apparently animals have become victims of fashion industry. Animal skin has been used to make fashionable clothes and these clothes sell at a high price. So some greedy people begin to kill animals in a large quantity. This irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings.

As far as I am concerned, something must be done to stop this illegal action. We believe "no buying, no killing". First, we must make concerning laws to protect these animals in danger. Second, we must take some measures to protect animals effectively. Animals are our friends and part of our environment. Third, we should raise peoples awareness to protect animals and our environment. In this way, we can build a harmonious society and ensure a sustainable development.

呼吁保护动物英语作文3

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 careBecause 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. WhyBecause 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.

Nowadays, the environmental protection is becoming one of the most important issues in the world. Being one of the members of our society, what shall we do to protect the environment

First, stop using plastic bags, boxes and bottles. Stores should be required to use the bags, boxes and bottles which are made from paper. Secondly, more and more trees and flowers should be planted to keep our surrounding clean. People must be required to plant plants around their houses and work places.

Finally, we must control the pollution by law, according to which, polluted water and air exhausted from factories should be forbidden.

These are some of the measures that we can take to protect our environment and they are not hard tasks for us. Remember, the earth is the only planet we could live at present.

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.

Whats 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.

[关于环境保护问题的英语作文

海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

导致海洋的盐度变化的基本过程有三个，其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。

这样由于盐留了下来，所以盐度增大。

当然，如果这种方式走向极端，将会余下白色的盐晶体。与蒸发相反的是降水，如降雨，由此水被加入海中，海水被稀释，从而盐度降低。

这种情形会发生在大量降雨的地区，或江河入海岸处。因此，盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。一般来说，在阳光很

强烈的热带地区，海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。同理，在江河稀释海水的海岸地带，海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。海水冻结时，溶于其中的物质被留了下来。这样，在新形成的海

水冰面的正下方的海水比在冰形成之前有更高的盐度。

当然，当冰融化的时候，会降低周围水中的盐度。

在南极洲边缘的威德尔海中，结冰过程增加低温海水的盐度，从而形成了浓度最大的海水。这些大密度的海水下沉，可以在世界海洋的深水域发现。

if the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. nevertheless, some of these small changes are important. there are three basic processes that cause a change in oceanic salinity. one of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. in this manner the salinity is increased, since the salts stay behind. if this is carried to the etreme, of course, white crystals of salt would be left behind.

the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. here the ocean is being diluted so that the salinity is decreased. this may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.a third process by which salinity may be altered is associated with the formation and melting of sea ice. when sea water is frozen, the dissolved materials are left behind. in this manner, sea water directly materials are left behind.

in this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.in the weddell sea antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. this heavy water sinks and is found in the deeper portions of the oceans of the world.

Excuse me waiter, there’s a shark in my soup

Some 200m years before dinosaurs made their appearance on earth and thus quite some time before Homo sapiens began celebrating nuptials at extravagant wedding banquets, sharks swam the oceans. Sharks are older than trees. They have survived at least four planetary mass extinctions.

在恐龙在地球上出现之前两亿年左右，也就是在现代人(Homo sapiens)开始举办奢华婚宴之前相当久远的时候，鲨鱼们就已经在海洋中游弋。鲨鱼比树还要古老。它们至少经历了四次地球物种灭绝，一直活到了今天。

The link between these ancient predators and contemporary wedding receptions is that, among Chinese people, it is a sign of generosity and prestige to serve guests shark-fin soup. Since there are more than 1.3bn Chinese people, and since they are getting more affluent by the day, that is of no little consequence to the shark population. Some 70m sharks are killed each year for their fins. Much of the time, the fins are sliced off with a blade at sea and the bloody shark torso thrown back in the water to die.

这种古老的食肉动物和当代婚宴之间的联系在于，在中国人眼中，请客人吃鱼翅羹是慷慨与体面的标志。由于中国有13亿多人口，并且中国人一天比一天富裕，吃鱼翅对鲨鱼数量可谓影响重大。为了获取鱼翅，人类每年要捕杀约7000万条鲨鱼。大多数时候，人们在海上用刀把鱼鳍割下来，然后便将血淋淋的鲨鱼躯干扔入海里，任由它们死去。

The California state legislature is debating a bill co-sponsored by Paul Fong, a Chinese-American Democrat, to ban the sale, consumption and trade of shark fin. Hawaii, Oregon and Washington state already impose similar bans. California accounts for 85 per cent of shark fin eaten in the US. The bill sailed through the lower house assembly, but is being held up in the state senate because of concerns it discriminates against Chinese Americans.

加利福尼亚州立法机构正在讨论由民主党人、美籍华人方文忠(Paul Fong)联合提议的一项旨在禁止贩卖、消费和交易鱼翅的议案。夏威夷州、俄勒冈州和华盛顿州已经实施了类似的禁令。加州的鱼翅食用量占到美国鱼翅总食用量的85%。州众议院会议已通过了此项议案，但因担心法案有歧视美籍华人的嫌疑，州参议院还未对其投票表决。

What people eat is, indeed, a sensitive topic and one that generates much hypocrisy. Different cultures have formed their own taboos about what is proper, and not proper, to eat. Muslims and Jews don’t eat pigs, Hindus don’t eat cows and most Americans don’t eat snake or whale. Jains, and vegetarians of all cultures, don’t eat any animals at all.

人们吃什么确实是一个敏感的话题，也会催生许多虚伪的作风。对于可以吃什么、不可以吃什么，不同的文化有着各自的禁忌。穆斯林和犹太教徒不吃猪肉，印度教徒不吃牛肉，而大多数美国人不吃蛇肉或鲸肉。耆那教徒(Jains)和各种文化中的素食主义者都不吃任何动物。

Westerners are particularly prone to turning up their nose at what other people eat. Their position is mostly illogical and sometimes offensive. They tend to mentally divide animals into those you eat (like pigs, sheep and chickens); those you cuddle or stroke (cats, dogs and horses); and those too ugly, unusual or intelligent to eat (say beetles, zebras and dolphins). Many profess to loathe barbarity – think clubbing seals – yet are happy to eat veal or to ignore what goes on in their friendly neighbourhood abattoir.

西方人尤其看不惯其它文化社会的人们所吃的东西。他们的出发点大多不合逻辑，有时可能还会触犯众怒。他们往往在心里把动物分为好几类：吃的(如猪、羊和鸡)、搂抱或抚摸的(猫、狗和马)以及太丑、太怪或太聪明而不能吃的(比如甲虫、斑马和海豚)。许多人都公开对残暴行为表示憎恶——例如用棍子猎杀海豹——但却爱吃小牛肉，或佯装对自己居住的友好社区的屠宰场里发生的一切毫不知晓。

Michael Moore, the American documentary film-maker, brilliantly – if possibly inadvertently – exposed this self-delusion in Roger & Me. In a scene that was meant to highlight the poverty of Flint, Michigan, a woman selling rabbits is shown asking customers if they want “pets or meat”. If the answer is “pet”, the cuddly bunny is handed over to a delighted child. If “meat”, the hapless creature is clubbed to death with a lead pipe and skinned on the spot.

美国纪录片电影制片人迈克尔?摩尔(Michael Moore)在《罗杰和我》(Roger & me)中绘声绘色地(也可能是不经意地)披露了这种自欺欺人的行径。在展现密歇根州弗林特(Flint)贫困状况的一个场景中，有个女人在卖兔子，她问顾客要买“宠物还是兔肉”。如果答案是“宠物”，她就把小兔子交给一个满心欢喜的孩子。如果答案是“兔肉”，她便当场用一根铅管把这个可怜的动物打死并把皮剥下来。

The richer societies get, the more finicky they tend to become. Many (including myself) waste half the animal they have had killed on their behalf, refusing to consume its organs, intestines, brain and so on. These parts are often eaten, and sometimes prized, in non-western societies, particularly in Asia. In their willingness to consume almost all the animal, both China and Japan score far better than most western countries.

社会越是富有，往往就会变得越挑剔。许多人(包括我在内)会浪费掉因为他们而被杀死的动物的一半，我们拒绝食用它们的器官、肠子和脑子等等部位。但在西方之外的社会、尤其是亚洲，人们通常是吃这些的，而且有时还会将其视若珍品。就吃下动物所有部位的意愿而言，中国和日本要远远排在大多数西方国家的前面。

Surely, then, one can’t object to eating shark fin? Yet one can and one should. The reasons are to do with conservation and our broader ecosystem. Some species of shark have been depleted by 70 per cent and a few, such as smooth hammerhead, bull sharks and tiger sharks, by 90 per cent or more. Sharks are the ocean’s top predators. Their absence causes havoc. Off the east coast of America, sharks used to eat bottom-feeding rays. With shark numbers massively depleted, the rays have had a field day devouring scallops, clams and oysters, rapidly reducing stocks.

这么说来，想必我们不能反对吃鱼翅了?不，我们可以反对，而且也应当反对。因为这关系到环境保护以及更广泛生态系统的保护。一些种类的鲨鱼数量已减少了70%，少数几个种类的数量减少了90%，例如平双髻鲨、牛鲨和虎鲨。鲨鱼是位于海洋食物链最顶端的捕食者。若没有它们，生态系统会发生混乱。在美国东海岸附近，鲨鱼通常以在水底觅食的魟鱼为食。由于鲨鱼数量急剧减少，魟鱼就会趁机吃掉很多扇贝、蛤蜊和牡蛎，使这些物种的数量迅速减少。

Once shark fins are dried and in jars, it is all but impossible to tell what kind of shark they came from or whether they were finned. At one store in the Sheung Wan district of Hong Kong, a city where half the world’s shark fin is traded, a salesman admits he has no idea whether the fins come from endangered species. His shop does not sell shark meat, and he says it could be true that the carcase is simply tossed into the sea. As well as the cruelty, there is also the incredible waste. The average shark stretches to about 10 bowls of soup.

鲨鱼的鳍一旦被晒干并放入罐里，便几乎无可判断它们来自哪种鲨鱼，或者是否是被割下来的。在鱼翅交易量占全球一半的香港，上环区一家商店的一位销售人员坦承，他不清楚店里的鱼翅是否来自濒危鲨鱼。他的店里不卖鲨鱼肉，并且他表示，鲨鱼的尸体被直接抛回海里可能是真事。岂止是残忍，这也是一种巨大的浪费。平均每条鲨鱼只能加工出大约10碗鱼翅汤。

Certainly, shark fin is traditional. As one writer points out, to ask people to stop eating it is the equivalent of suggesting Americans give up turkey for Thanksgiving. There is doubtless a case for banning other types of food, such as some types of caviar and some species of whale. But cultures are not immutable. Traditions change, especially when they are unsustainable.

不错，鱼翅是一种传统食物。正如一位作家所指出的那样，要求人们不吃鱼翅就好比让美国人过感恩节时不要吃火鸡。我们无疑有理由禁止食用其它食物，比如某类鱼子酱和某些种类的鲸。但文化也不是一成不变的。传统会发生变化，尤其是当它们难以为继的时候。

Fortunately, many of the most prominent campaigners against shark fin are Chinese, with Yao Ming, the recently retired basketball sensation, among the most passionate. In Hong Kong, where shark fin used to be de rigueur at Cantonese banquets, many young people refuse to eat it. Besides, sharks have less cachet now they are siphoned from the oceans on an industrial scale.

值得庆幸的是，在反对吃鱼翅的最著名活动人士之中，许多都是中国人，比如近期退役的篮球明星姚明，就是行动最积极的人士之一。在香港，鱼翅曾是粤宴上的必备菜肴，但如今许多青年人拒绝食用鱼翅。此外，在捕杀鲨鱼实现工业化规模的今天，鱼翅的身价已大不如前。

In Canada, more than a few ethnic Chinese couples have made a show of not serving shark fin at their wedding. Judy Lao recently told the Vancouver Province why she didn’t have it at her reception. “We don’t really care, our friends don’t care, and shark fin has no nutritional value anyway,” she said. “So why should we serve it?” Why indeed.

在加拿大，许多对华裔夫妇已做出表率，在婚宴上不供应鱼翅。Judy Lao最近向《温哥华省报》(Vancouver Province)解释了，为什么她的婚宴没有上鱼翅。“我们并不介意这些，我们的朋友也不介意，再说鱼翅根本也没有什么营养价值，”她表示。“所以，我们为什么要上鱼翅呢?”确实，这有什么必要呢?
