Let’s Do Something to Save Our Environment

It is recently reported that some rivers and lakes have dried up in South China. A lot of fishes died. The bottoms of the rivers and lakes have become grass land. The water is becoming less and less because of the bad weather.

So everyone should do something to save our environment. First, we should save every drop of water, such as turning off the taps after using it and recycling the water. For example, we can water the plants and clean the rest room with our used water. Second, we should save energy, such as less turning on the lights and turning off the lights when we leave;Do more walking, more bicycling and less driving and so on. Third, we should ask our government to control the pollution from the factories.

Let’s act now from everything to save our environment. Don’t let our tears be the last drop of water in the world!

"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!

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.

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。

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。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。

为了保护环境，各国政府做了超多的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。

我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当透过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自我。

[英语作文保护环境的

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。

The earth mother as the cradle of life, human like a spoiled child of the earth. She give us everything we need for life leave her, we will get nothing. Beautiful living environment is the basis of which we live, but now, our environmental protection consciousness is more and more weak. Though, we all know that protect the environment, but not the property of the consciousness of earth, destroy the originally beautiful environment; In fact, in life, as long as pay attention, everywhere can be environmental protection.

In those restaurants everywhere can see around us, the boss in order to achieve "health" standard, and unconsciously extensive use of wooden chopsticks that were made from wood; Cost is huge, hits the verdant trees with bangs fall, only the birds were forced to leave, a group of a group of lovely animals homeless again, but as they didnt see, originally natural ecological environment destroyed by them, just like that. Not only did not have the forest, and animals are not spared. Recently, some cantonese put smart cute little monkeys alive opened the brain had his head down, they looked at each cute little monkey innocent dead, but still, this is what a horrible thing!

We as the master of the earth, if you dont cherish everything now, that this beautiful environment will leave us early. At that time, we will face catastrophe, the earth will be scarred, and hurt; So we should do owners should do, well protect our survival environment, do not deliberately to destroy, remember: to protect the environment, is to protect the future of mankind.

地球母亲就像是生命的摇篮，人类就像是地球的骄子。她，给予了我们生活所需要的一切离开她，我们就一无所获。美好的生存环境是我们赖以生活的基础，可是现在，我们保护环境的意识却越来越淡薄了。虽然，大家都知道保护环境，但却不自觉的掠夺地球的财产，破坏原本美丽的环境;其实，在生活中，只要留心，处处都能环保。

在我们周围的那些餐馆中随处可以看到，老板为了达到“卫生”的标准，而不自觉的大量使用那些用树木做出的木质筷子;为此付出的代价是巨大的，一棵棵青翠的树木随着巨响而轰然倒下，一只只鸟儿被迫离开，一群又一群可爱的动物无家可归，可他们却当作没有看到，原本自然的生态环境就这样被他们破坏。不仅森林没有了，而动物也是不放过。最近，一些广东人竟然把机灵可爱的小猴子活活的把头打开把脑子吃了下去，他们看着一只只可爱的小猴子无辜的死去，却还是无动于衷，这是多么令人发指的事呀!

我们身为地球的主人，如果不珍惜现在的一切，那这美好的环境一定会早早的离开我们。到时候，我们会面临灾难，地球也会伤痕累累，而受到伤害;所以我们应该做到主人应该做的事，好好的保护我们生存的环境，不要蓄意的去破坏，要记住：保护坏境，就是保护将来的人类。

This is the composition about to protect and love our environment. Indeed, we only have one earth, it is essential and imperative for us to treat it nicely. Or else, we will be the one suffering. As a matter of fact, a great number of animals and plants had extinct. All this was substantially because of we human being. And a large number of them are endangered. If this does not imply that we are not obliged to do something, the world is going insane and will be destroyed. To stop this from happening, we have many options. First and foremost we should start from ourselves. Do as what a perfect citizen should do. Then, restrain the factories from polluting, this can be done by establishing laws and rules. If we united as one, nothing is impossible.

If you really love and want to protect their birds, then: What kind of bird you do not raise!

Because there does not belong to a bird cage is not their natural attribution! And then a large cage is not!

The vast land of endless blue sky is their home!

Freedom is part of each birds life!

And those around you and then tell you to do the same thing! And refused to eat any non-breeding birds, eggs! Do not buy any use of wild birds, feathers, or other organs do arts and crafts!

Then, if you have a spare then please contribute to the Association for the Protection of Birds, as volunteers, willing to publicize knowledge of the Protection of Birds

Please send them to their friends as human beings who are not and never will be the master!

The Protection of Birds

1, to contain the phenomenon of hunting

Is a lot of expensive, rare birds has become the food on the table, people kill objects. A serious problem has been exposed, to know If you do not take measures on a shotgun I think people will be the last bullet for themselves.

The first is "blocking" is to strengthen the intensity of market management, block of wild animals in the market, distribution channels, those measures were the reason to kill wild animals will be set the expense of France, still go its own way, wantonly killing of wild animals, a great The reason is because the wild animals get sold on the market can Maihao price. Measures to kill the game as long as they can not be sold in the market, and will be punished by law, then hunting of wild animals, the phenomenon would be greatly reduced.

The second is "Shu" is to strengthen publicity and education of the people, so that people from the very recognition of the importance of protecting wild animals, so that people have the concept of the rule of law in this regard is only to clear the peoples ideological obstacles to practical action in do the work of protecting wild animals, Mao Zedong once said: "The people are in this war." Therefore, to fight this war, the protection of wild animals, we must do the peoples work.

The third is the "fight", that is, the people on the basis of clear, in-depth relied on the people, the establishment of various reporting system, where upon receipt of illegal killing, selling message, it should immediately launch an attack. Which one dares to abandon the expense of France, then waiting for him will be the legal penalties, not soft. "Beating" is a means, only the crackdown, in order to protect wildlife resources.

The fourth is to "maintain", that is, the protection of wild resources, based on the appropriate to meet the needs of the people to establish a base of wild animal husbandry. Many birds have a high food value, medicinal value. Bird could sideline the rural economy be promoted so that farmers towards the road to riches; objectively has reduced the peoples nature to kill wild animals to protect a limited number of animal resources. This can serve two too, why not?

2, the establishment of protection agencies to combat illegal hunting

我们要保护野生动物，因为我们保护野生动物，野生动物对我们人类也会很友好。

比如说燕子，燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们，它们会吃掉那些常常来搔扰我们的蚊子，让我们更好地生活吗？没有了燕子，我们的周围变得很多害虫，这些害虫对我们人类有很大的坏处呀！

我还举个例子。比如说青蛙，青蛙也能帮我们吃田里的害虫，可以说是田里的警察。我们支捕杀他们，一旦没有了青蛙，田里的害虫越来越多，害虫不断地吃菜，难道我们会有美好的丰收吗？

我还举个例子。比如说啄木鸟，啄木鸟是森林中的医生，它可以帮我们吃掉树里的害虫，让树恢复健康。我们杀害它们，树木的害虫会越来越多，树木会慢慢地减少。地球上没有树，会发洪水、地震。

我最后举个例子。比如说猫头鹰，猫头鹰捉田鼠，是对我们人类有好处的，人类却常常捕猎它们。没有猫头鹰，田鼠会增加。田鼠吃的庄稼和菜就更多了，我们人类一样没有好的收成。

所以，我们要保护以上的动物。同时，我们还要保护其他的野生动物！

Animals are people friends,they believe that human not to hurt people.But people are constantly harm to them.

We shouldnt do it.We are now protected animal,make it not hurt,to serious blow the killing animals.Because -- we are animals ah,senior animals.If we were to slaughter,and our family?It is the same with animals!

Because we are a family,so please everyone together to protect animal!

I have a white dog.Its name is Bobo.She is a female dog.She comes from Beijing,China.She has two big eyes and a small month.She wears white clothes.

She often walks around at home.It has nothing to do.She likes eating ice-cream so much,So do I.When I eat ice-cream,she will look at the ice-cream carefully.So I will give her some to eat.

Animal Farm tells a story that one day the animals overthrow the farmer Mr. Jones, and found their own regime, called Animal Farm They adopt Seven Commandments of Animalism, of which the most important is All animals are equal。 Pigs are the leaders of the operation of the newly start-up farm.Thanks to the right lead of the pigs and selfless and hardworking of all animals, the Animal Farm develops good enough to their demands.

However, the leaders separate into two factions soon after. As a result, Snowball is expelled by Napoleon as a betrayer. Although many animals remember that Snowball is a brave leader, they firmly believe they were wrong and Snowball is a bad animal indeed after brainwashing Napoleon offered. What’s more, the Seven Commandments of Animalism had also been changed. Finally, the Animal Farm becomes quite different from what they hope it to be at the beginning.

From the novel; I expressively feel the great power of faith. With the faith of Animalism, they finally found their regime, and struggle the equal from humans. And because of the faith, Napoleon can still rule the wretched animals, even though Snowball has gone. In our daily life, faith is indispensable as well. Faith just as flame, guiding us and supporting us when we feel frustrated as well as every time we need power to keep going ahead. When the Animal Farm is in mess, the animals still believe in their faith and Animalism. As to us, this believing is needed. Sometimes we may think we are in a wrong road to our dream, or we lose heart of ourselves, considering we aren"t as well as respect, we need believe. A b faith just likes a protection, and we are protected by it from kinds of difficulties.

There is no doubting the great benefits which scientific advances have brought us 。 Yet we have become increasingly aware that some technologies’ developing brings unexpected and harmful side effects 。

A number of factories spring up like mushrooms ，exhausting much waste gas ， which leads to the greenhouse effect and air pollutions 。 Plentiful trees are cut down that causes the lands to change into the deserts 。 At the same time ， varieties of species are gradually extincting 。 These phenomenons give us clear warnings of the dangers of failing to live harmony with nature 。

We ought to set up a profound mind to protect our environment 。 For the governments ，they should make detail laws and policies to observe the behaviors of destroying the environment 。 Factories should exhaust polluted water or gas after dealing with rather than merely pursue the economic interests 。 Planting as more as possible trees ， in case of the water and soil erosion 。 For farmers ， they must reduce spraying the insecticides 。 We also must make less use of plastic materials and one—off products 。 In addition ， we wouldn’t throw the rubbish anywhere 。 Thus ， we at least can maintain our environment in a good state 。 However ， that’s not enough 。 We are supposed to work harder to protect our environment 。

作文【一】

One day Sun Wukong together with his master and brothers was walking across a river. Suddenly his master fell off the horse by the bad smell of river water. They found the water so dirty that they could hardly breathe.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed. If the river water all over the country is polluted like this, no living things will exist in the water. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

Dear editor,

Environmental problems are becoming more and more serious all over the world.

With the development of industry and agriculture, cars make great noises and give off poisonous gas. Because of population expansion and overdevelopment, resources has become less and less. Trees on the hills have been cut down, and waste water is being poured continuously into rivers. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man’s existence.

We must face the situation that exists and take actions to solve our environmental problems. We hope that all these measures will be effective and bring back a healthful environment.

Yours truly

Everyone should protect the environment, this is the law of nature, if not protect the environment, the world will be contaminated.

To protect the environment from every bit of small start, and I have not done well. Have a New Year, we went to shun feng mountain park, riding a bicycle, we were hungry, we bought a small bag of snacks to eat, while I, eat snacks, I happy too much because it is over, so casually took me to once eat 7 packet snacks packaging thrown on the ground, and then I went in a convenience store in watching TV, while todays TV is very good-looking, half an hour later, I put the mother with all I said before, all my thoughts are indulged in the drama. After 30 minutes, I didnt think of it, but, at that time, his mother angry of say: "you this smelly wenches, didnt I tell you before to protect the environment, you forget?" I said: "Im not forget, I just from watching TV." Mother said: "some important watching TV, or picking up litter some important?" I said: "rubbish." Mother said: "you hurry up to pick up."

And then, I picked up a small pile of junk, throw in the trash, I apologized to his mother not only, I also to shun feng mountain park, sweep the floor every aunt to recognize the fault. Because, if everyone throw a piece of garbage on the ground, and then will add burden to clean the aunt. If you see a piece of garbage on the ground, then you are curved waist, and activities, do a man to protect the environment, is to clean the aunt to reduce burden...

, although it has been over the past year, I learned about it, if the world all throw a piece of garbage on the ground, the whole earth will become a waste, so each of us should protect the environment, protect the earth, the world will be more beautiful!

人人都要保护环境，这是大自然的规律，如果不保护环境，世界就会被污染。

保护环境是从一点一滴的小事做起，而我却没有做好。有一次过新年，我们去顺峰山公园游玩，骑完自行车，我们个个都饿了，我们买了一小包零食来吃，而我，吃完零食，我因为高兴过头了，所以随手就把我吃过的7包零食的包装扔在地上，然后我进去便利店里面看电视，尽管今天的电视剧很好看，过了半个小时，我把以前妈妈跟我说的话忘得一干二净，我所有的心思都沉迷在这个电视剧里面。在过了三十分钟，我才想起来，可是，这时候，妈妈生气的走过来说：“你这个臭丫头，难道我以前跟你说的要保护环境，你都忘了吗?”我说：“我不是忘了，我只是顾着看电视。”妈妈说：“看电视重要一些，还是捡垃圾重要一些?”我说：“捡垃圾。”妈妈说：“那你快点捡呀。”

然后，我捡起一小堆垃圾，扔进垃圾桶，我不但向妈妈认错了，我也向顺峰山公园的每一个扫地阿姨认了错。因为，如果每个人都扔一块垃圾在地面，那么就会给清洁阿姨增加负担。如果你看见一块垃圾在地面，那你就弯弯腰，动动手，做一个保护环境的人，那么就会给清洁阿姨减少负担……

虽然这件事已经过去一年了，但是，这件事让我学会了，如果世界上都扔一块垃圾在地面，那么整个地球就会变成一片废区，所以我们每个人都要保护环境，保护地球，世界才会更美好!

Animals are peoples friends, we should protect them.

If there is no animal on earth, there would be no human. Animal is a most of the earths food chain, if animals disappeared, we human beings will be extinct. For example: the frog disappeared, there is no animal pests to catch paddy fields, crops will not grow, humans have no food; If there is no tiger, the rabbit will excess breeding, our food is likely to be a rabbit eat didnt; If there is no owls, mice will encroach on our territory...

The earth is a big family, not lack of anyone, without animals, we humans situation, we should all band together and protect small animals.

动物是人们的朋友，我们应该保护它们。

地球上如果没有动物，就没有人类。动物是这个地球生物链的一大部分，如果动物消失了，我们人类也会灭绝。例如：青蛙消失了，就没有动物去捉稻田的害虫，农作物也就无法生长，人类就没有食物;如果没有老虎，兔子就会超额繁殖，我们的粮食就可能会被兔子吃没了;如果没有猫头鹰，老鼠就会侵占我们的地盘……

地球是一个大家庭，缺谁都不行，如果没有动物，我们人类的处境可想而知，我们大家应该团结起来，保护小动物。

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

人类是生存在这个地球上的生命物种之一，我们在爱自己同类的同时，也应该尊重其他生命，善意对待和爱护我们身边的小动物。

每个人在一生之中，都会与各种生命相遇：小猫、小狗、小兔子、小乌龟??这些小动物是我们的伙伴、朋友，甚至家人。每一个有爱心的人，懂得生命意义的人，都会知道怎么善意关爱自己的伙伴。

被挖掉眼球的小狗、被汽油烧焦的小猫、被恶意投毒而死的动物??当这一桩桩骇人听闻的残害动物的事件不断发生时，我心里总有说不出的沉痛，我想这是任何一个有良知、有爱心、有正义感的人所不能容忍的事情。

虽然大多数人珍视身边动物带给我们的爱和友情，但是仍有人不负责任地抛弃他们的宠物，甚至虐待它们，于是才有了这一只只的流浪动物。

绝大部分城市流浪动物的生存状况令人十分堪忧：它们被遗忘在角落的生命，不受重视；它们身体遭受病痛的折磨；它们无时无刻不在忍受着残疾带来的痛苦；它们承受未绝育带来的生殖繁育风险，小宝宝一出生就面临着巨大的死亡危机；它们经常要面对酷暑、严寒和饥饿，四处寻找躲藏之处；它们时刻面临着各种危险，每一刻都有可能惨死在街边；它们甚至还要面对一小部分人为满足自己变态的心理而做出的种种虐待和伤害??

残酷的生存环境、悲惨的生活遭遇，使得我们身边的这些伙伴的生命凋零??

真正的爱是对弱者或蒙难者发自内心的悲悯和关怀，是不假思索伸出的援救之手。在此，我郑重呼吁各界尊重生命、关爱生命的有识之士：

1. 尊重生命，尊重动物，不吝啬自己的爱心；

2. 无论自己的宠物年老、体弱、生病还是残疾，都不放弃、不抛弃它们；

3. 保证动物不受饥渴、伤害和疾病威胁；

4. 保证动物有一定的自由，让它们生活无所恐惧，能自由表达天性；

5. 有能力和条件的人，对流浪动物进行有责任感的收养、领养、寄养；

6. 依法合理、人道的利用动物；

7. 不从非法商贩处购买伴侣动物；

8. 不虐待、不伤害流浪动物；

9. 将“关爱生命，善待动物”的理念传播给身边的每一个人。

[保护动物倡议书作文两篇

今天，我读了安徒生童话里面的《维菊》。这篇童话主要讲了一只百灵鸟被两个小男孩关在牢笼里，那朵小维菊也关在里面了，它想安慰百灵鸟，可不知道说什么好。最后没人管这只百灵鸟，百灵鸟就渴死了，维菊也枯死了。

从这篇童话故事里看到：我们应该保护动物、植物，不能学故事中的小男孩，在百灵鸟能唱歌的时候，他们不爱护它，让它在牢笼受苦受难，现在它死了！然而却得到了这样尊荣和许多眼泪。

不过，在生活中人们经常挂在嘴边说，要保护植物、动物，行动上却没有表现出来，有些经常乱拔花草，还有些人总喜欢捉鸟儿。看来他们不知道这植物、动物的用处，如植物可制造出二氧化碳，使我们的空气更加清爽；动物的粪可以让植物健康地生长，这样植物就更加可以制造出清爽的空气。

看来，我们必须保护动物、植物。让我们共同生活在一个清爽、湛蓝的天空下！
