关于保护老虎的英语作文【精品20篇】

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。

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。那我们应该如何保护好自己的家园，保护好环境呢？以下是小编整理的英语作文环境保护，供大家参考。

Cherish resources, protecting the environment, only a few words, this is very important, for example, we go out to play, etc. The words will be held.

Earths resources are limited, could have uninterrupted growth, but because of the excessive development of people, these resources can hardly continue to regeneration. Water is indispensable to mankind, it gave birth to all life, he is our mother, but water has always been some dont know to cherish, will only waste, wasted a lot of water on earth, but only very little for us to drink the water, the other is the water of the sea, so we should protect water resources. Biological resources is very important also, he can let us survive, so we cant destroy any creature in the food chain, if damaged, will be big disaster, there are always some damn poachers, the capture of wild animals, such as elephants, rhinos, etc., so we need to protect any type of resource, let him not be damaged.

Protect the environment, cherish resources, from small start.

珍惜资源，保护环境，这单单几个字，却非常重要，比如我们出去玩等地方都会有这几个字。

地球上的资源是有限的，本来可以不间断的生长，可是由于人们的过度开发，这些资源都没法继续再生了。水资源是人类不可缺少的东西，它孕育了一切生命，他就是我们的母亲，可是水资源总是被一些不懂得珍惜，只会浪费的人浪费了，地球上的水很多，但只供我们饮用的水很少，其他的都是海水，所以我们要保护水资源。生物资源也很重要，他可以让我们生存下去，所以我们不能破坏食物链中的任何生物，如果破坏了，将发生大灾难，总有一些可恶的偷猎者，在捕捉野生动物，如大象，犀牛等，所以我们要保护任何资源，不让他被破坏。

保护环境，珍惜资源，从小事做起。

今天我来到了我爸爸上班的地方张集。张集是一个小镇，它是我的老家 。

Today I went to my father work place Zhang ji. A set is a small town, it is my hometown.

小时候我在那里住的时候，环境特别的不好。人们根本不保护环境。垃圾四处‘‘流浪’’，屋前屋后、路旁岸边都是垃圾的家。夏天苍蝇蚊子大聚会，散发出浓烈的腐臭味，人们过路时得捂着鼻子才行。冬天寒风吹来，纸片、树叶、塑料袋漫天飞舞，真像‘‘天女散花’’，人们不戴口罩眼镜还真不敢出门呢。

When I was a child living there, especially bad environment. People dont protect environment. Garbage everywhere wandering , house, roadside banks are rubbish home. Summer flies mosquitoes big party, stink smell strong, people crossing the road when a clutching his nose it. The winter wind blowing, leaves, paper, plastic bags flying all over the sky, like The heavenly maids scatter blossoms. , people dont wear masks glasses really dare not go out.

如今沙漠正在急剧扩大，人们也已经知道了保护环境的重要性。瞧，现在张集就像一个大森林，街道上干干净净，没有一点灰尘。绿树成荫，鲜花盛开，空气清新，天空湛蓝。

Now the desert is expanding rapidly, people already know the importance of Protect environment. Look, now a set like a forest, the streets clean, no dust. Trees, flowers in full bloom, the air is fresh, the sky is blue.

你看，如今我们在这么好的环境下生活，多么幸福啊，我们要把保护环境进行到底，让老家永远那么美丽。

You see, in such a good environment we live now, how happy ah, we want to Protect environment through to the end, let the home is always beautiful.

人类在变好，环境也在变好，让我们的环境一直好下去吧。

The human is changing, environment is also good, let our environment have been down.

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.

The earth is home to all of us live together, without the earth, we will not be able to survive. So, we should care for the earth to protect our environment.

Now, the environment and the earth has been destroyed seriously, such as: factories emit smoke, the sky to the blackened, moreover, the factory also emit dirty and smelly sewage, the river was dark; And, whats more, people also deforestation, hits the innocent trees are cut down, from time to time will blow winds.

You look, now the environment has been damaged so serious, we should start from their own care for the earth to protect environment, such as: save every piece of paper, because, each a piece of paper is made from trees, each producing one ton of paper, will burn a few big tree; Save every once electricity, every time because of the electricity, let power plant chimney smoke rose from the...

Human, please take good care of our home, to his home, please take good care of the earth to protect our environment.

地球是我们大家共同生活的家园，如果没有了地球，我们将无法生存。所以，我们要保护环境爱护地球。

现在，环境和地球已经被破坏的很严重了，比如：工厂里排放出滚滚浓烟，把天空都给熏黑了，而且，工厂里还排放出又脏又臭的污水，把小河都染黑了;而且，更严重的是，人们还乱砍乱伐，把一棵棵无辜的大树都砍伐倒了，时不时就会刮起一阵阵狂风。

大家快看，现在环境已经被破坏的如此严重了，我们应该从自身做起保护环境爱护地球，比如：节约每一张纸，因为，每一张纸都是用大树做的，每产一吨纸，就要消耗几棵大树;节约每一度电，因为每发一次电，就要让发电厂的烟囱冒出滚滚浓烟……

人类们，请大家爱护自己的家园，为了自己的家园，请大家保护环境爱护地球。

I keep it all the time, now so many years have passed, I find most of my classmates have worn glasses, while I not one of them. Thanks to my parents, I keep the good eyesight now.

The picture shows the pollution caused by chimneys of the factories in cities. Often, the sky is covered by large clouds of smoke from chimneys. The air is nearly suffocating, especially in the evening as it becomes cold and the smoke is spreading everywhere. The scene reminds us of the end of the world.

From the picture we can infer that the drawer of the picture intends to convey to the readers that unplanned factories has brought about great hazards to the city air condition. Due to planning mistakes, factories were usually placed in the center of cities, among residential and business districts. Besides, nearly every block has several chimneys for the heating system, which makes the whole city immersed in thick columns of smoke. As a result, respiratory diseases have been reported to be rising and old people dying of the worsening air pollution.

Pollution is really a hot issue in the world. If we don’t take useful measures, we may live in terrible surroundings, and some unexpected results may come out in the end. So, what we should do is to bring down the problems caused by chimneys. For one thing, factories with chimneys should be moved out of the center of the city and it should be made sure that the waste gases are at least not poisonous. For another, other means of heating should be developed to stop using coal. In a word, in the city there should be no coal, no chimney, and no smoke to pollute the air.

Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.

The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the worlds 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,

Marine living resources are likely to cause more damage.

The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.

海洋环境是一个在水里,海水宽容水解产物和悬浮物,海底沉积物和海洋生物,包括复杂的系统。海洋丰富的生物资源、矿产资源、化工资源和权力资源是人类不可或缺的资源宝库,与人类生存和发展的关系非常密切。

当前海洋保护的主要目的是保护海洋生物资源,以免失败,为了人类的可持续利用。特别是,优先保护那些有价值的和极度濒危的海洋生物。根据联合国的调查,由于过度捕捞,偶然捕捉和杀害非目标允许捕猎海洋,沿海岸线建设、红树林森林砍伐、广泛的海洋污染,至少世界上25个最有价值的渔业资源的枯竭,鲸鱼,海龟、海牛和许多其他海洋动物面临灭绝的风险。预计,随着海洋开发规模的扩张,

海洋生物资源是可能造成更大的伤害。

第一个海洋保护的权利的任务停止对海洋生物资源的过度开发,其次保护海洋生物的栖息地或栖息地,特别是他们的迁移、产卵、觅食,避免捕食者海岸滩涂,河口,珊瑚礁,有必要防止重金属、农药、石油、有机和容易产生富营养化等营养物质的海洋污染。保护海洋生物资源的自然再生能力和水净化能力,维护海洋生态平衡,以确保可持续的人类开发和利用海洋。

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.

Stepping into the new century, environment pollution has become more serious than ever since. There are different kinds of pollution. Such as, water pollution, air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. Where all these pollution comes from? To a large extend, the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel, people cut down trees and dig more corals. But the growing needs for energy are hardly to meet. Countless private cars on the street, the gas stations are short of gasoline, even the government has raise the price so many times in order to control the needs of gasoline, but it’s still not working. Overusing the natural resources has already affected the ecological balance. However, the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.

The government should put forward some more strict laws to prevent the environment from being further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again. Only in this way, our earth could be a better place to live in.

进入新世界以来，环境污染比任何时候都要严峻。有各式各样的污染：水污染，空气污染，噪音污染等等。看起来我们活着一个四周都是污染源的星球。那么，这些污染是从何而来的呢?在很大程度上，环境被破坏就是我们为快速的经济增长和人口增加所付出的惨烈代价。为了得到更多的能源，人们砍伐树木，挖更多的煤矿，但是还是难以维持日益增长的需求。不计其数的私家车充斥着公路，加油站的汽油严重短缺，政府多次上调油价也未能阻止私家车对汽油的需求。自然资源的过度利用已经影响到了生态平衡。然而，工厂依旧向外排放有毒气体，把工业废水倒入河里。人们依旧缺乏保护环境的意识。我认为人们应该做些事情了。

政府应该施行一些更为严格的法律来防止环境被进一步的破坏掉。他们应该让人们了解到保护环境的重要性。我们要在保持经济发展和环境保护中找到平衡点。在沙漠中植树造林，停止砍伐森林。禁止工厂往河流里直接排放废水。鼓励人们用交通工具上班。政府和普通民众都应该携手保护环境，让我们的家园变得干净整洁。只有这样，我们的地球才能更适合人类居住。

On Water Shortage

No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted. Actually, it has become so widespread that it has severely affected peoples daily life and hindered the development of the global economy.

A number of factors could account for the problem, but the following might be the critical ones. First, with the development of agriculture and industry, an increasing amount of water is needed. Secondly, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. Whats worse, pollution and waste of fresh water aggravate the situation.In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water. With these measures taken, it is reasonable

for us to expect a brighter future.

Man and His Environment

Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reserviors out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.

However, mans changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.

Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to mans existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise,man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings.

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。

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。 The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

The Marine life environment is a complex system including seawater, sea water content and suspension, seabed sediment and Marine life.The abundant biological resources, mineral resources, chemical resources and power resources of the sea are the indispensable resources of human beings, which are closely related to the survival and development of human beings.

The main objective of Marine conservation is to protect Marine life resources so that they are not depleted for sustainable use.Special priority should be given to protecting Marine life that is valuable and endangered.According to the relevant departments of the investigation, due to overfishing, accidental killing of non-target to allow hunting of Marine, coastal tidal flats in the engineering construction, mangrove deforestation, widespread Marine pollution, at least 25 in the worlds most valuable fisheries resources exhausted, whales, turtles, manatees and many other Marine animals are in danger of extinction.With the expansion of Marine development, the potential for greater damage to Marine biological resources is expected.

Marine conservation of the first task to stop the excessive use of Marine biological resources, secondly we must protect Marine habitats or niches, especially their migratory, spawning, feeding, avoiding DiHai coast, beaches, estuaries, coral reefs, to prevent the heavy metals and pesticides, oil, organic matter and eutrophication of nutrients, such as pollution of the sea.To maintain the renewable capacity of Marine biological resources and the natural purification capacity of seawater, maintain the balance of Marine ecology and ensure the sustainable development and utilization of the sea.
