room for collecting scripts and paintings. There was another room to store
clothes and shoes in the old times. The next room was for collecting the daily
necessities in the old days. In a word, all the things in it had a long history.
I learnt some knowledge from it.

+ 加入清单Nowadays, with the improvement of the people’s living standard, some people form a habit of raising small or domestic animals as pets. Some raise small dogs or cats as their pets while others raise various birds or fishes as their pets. There are still even some people raising snakes and other unusual animals as their pets.
Does anyone have the same opinion of raising animals as pets? No, some people object to the idea of raising animals as pets. To them, animals have their own right to live a natural life like human beings. On the other hand, the way people raise animals as pets have a negative influence on the surroundings such as dogs’ barking at midnight, dogs’ chasing people on the street and so on. What’s more, some animals will transmit some diseases.
In my opinion, I do not like the idea to raise animals at pets. Animals have their own right to lead a life as they like. We should not deprive them of their natural right. In this way, we will live in a peaceful world in harmony with the other living creatures.
如今，随着人们生活水平的提高，有些人养成了饲养小动物或家畜作为宠物的习惯。一些养小狗或猫作为他们的宠物，而其他人饲养各种鸟类或鱼类作为他们的宠物。甚至还有一些人饲养蛇和其他不寻常的动物作为他们的宠物。
任何人都有相同的意见，饲养动物作为宠物吗?不，有些人反对将动物作为宠物饲养。对他们，动物有他们自己的权利，生活像人类一样自然。另一方面，人们饲养动物作为宠物的方式对环境有负面影响，如狗的叫声在半夜，狗追逐人在街上等。更甚的是，有些动物会传播某些疾病。
在我看来，我不喜欢养宠物。动物有他们自己的权利，过他们喜欢的生活。我们不应该剥夺他们的自然权利。这样，我们将生活在一个和平的世界中，与其他生物和谐相处。

Panda is one of the scarcest animals. People in the world like it very much. There used to be many pandas in China long ago. As the balance of nature was destroyed and the weather was getting warmer and warmer, pandas became less. But at present, the number of pandas is increasing year by year. There are now so many pandas that some are being sent to other countries so that people there can enjoy them.

小狗的经历危险也有几次。第一次是掉进了河里，幸好被人发现拉了上来，喂给它吃药，不久就好了。还有几次是被毒狗的人毒了几次，幸好也被及早治疗，才得脱险了。从那以后，它就能嗅出那些食物有毒，哪些食物无毒。后来，我家的狗再也没中过毒。它够机灵吧!
我喜欢我家的小狗。我希望它永远伴随我左右，陪我快乐成长!

我们生活的地球正在迅速恶化，我们不得不注意一下自己的生活环境有没有对大自然造成危害，大家必须必须别乱丢杂物，特别是那些污染严重的垃圾，比如废电池，因为一节废电池中所含的重金属，如果流到清洁的水中，它造成的污染是非常厉害的，其次要尽量节约纸张、铅笔等树木造的物品，因为浪费了这些东西就是毁灭森林。还要尽量少用一次性饭盒、筷子和塑料袋等物品，以免造成不必要的浪费和减少垃圾的产生。
还有一些小建议：走时要随手关总开关，以免电器过热爆炸，浪费钱又浪费电，要节约用水，刷牙时要关紧水龙头，洗菜水可以淘米，淘米水可以浇花，洗衣水可以拖地，如此就可以减少一些浪费了。不要随意捕杀野生动物，一二级保护动物是绝对不能杀的，但也别捕杀青蛙等常见动物，因为青蛙为我们吃掉1.5万的虫子，而且大部分是害虫。有些人经常不以为是，依旧我行我素，所以我们要尽量少吃野生动物，导致他们野生动物销售额下降，不再捕杀野生动物。
我们的森林被称之是氧气加工厂，所以要爱护花草植物，不要破坏城市绿化，还要积极参与。而且还要少砍伐树木，别浪费木质的物品，因为浪费了这些东西就等于毁灭了森林，所以要少用，来保护越来越少的森林。

+ 加入清单当这个星期六下午4时少年宫的大门一敞开，我们就像一群才长了翅膀的雏鸟叽叽喳喳地飞向自己翱翔的蓝天。对我们这一只只小鸟儿来说天空是多么湛蓝，多么地广阔呀!
忽然一个身影映入我的眼帘一只浑身碧绿脖子发蓝，身高约七厘米的小鸟。咦?它怎么会有一张小巧的嘴呢?对了，这不就是常说的红嘴相思鸟吗?遇见了一只这么名贵的鸟儿，当然要逗逗它，想罢，吹了一声响亮的口哨。就这么一晃眼，鸟儿不见了，再望望前方我又看见了那只色艳迷人的小鸟，不过，这次是在一位眼疾手快的妇女手里。我呆呆地站在一旁心里有点矛盾，到底要不要救这只小鸟呢?
等我回过神来已经有许多小孩围在了妇女的身边，每个人都想玩弄一下这个可爱的小东西，“让我来玩一下!”“能给我摸摸吗”“真可爱”“它的毛真滑!”……到等他们都渐渐散去后我与小相思鸟的目光发生了碰撞，我仿佛能感受到小鸟眼神中的痛苦与哀求。我于心不忍，但总不能坐视不管让鸟儿饱受痛苦吧?当我还在思索时又有一个调皮的小男孩走了过来抢走了红嘴相思鸟，他一边拨弄着小鸟深绿色的翅膀和小小的爪子，向前走去。小鸟似乎在发抖着，更是用一种忧伤的眼神看着我，指望有一位救星。我这才鼓起勇气向小男孩走去小声地提醒道：“快放了它吧，它也很可怜。”
结果真是出人意料，那个小男孩一声不响地推出手，慢慢地端详着这只美丽的小鸟，最后张开双手放飞了这只可爱的小鸟。我们抬头观望，天空中却不见了它的身影，耳边却响起了一清脆的鸣叫，鸟儿，是你吗?是你，在谢谢我吗?
不管怎么说爱护小动物是每一个人的责任。

+ 加入清单Animals are friends of human beings. An animal is dependent on the human, also, the human also cannot leave the animals.
Long, long ago, animals and humans are a good friend. They help each other, rely on each other, get along with, who also cannot leave the who. However, with the passage of time, because of human beings, the animals with human relations soured, and there are more and more serious trend.
First of all, human beings to animals is wanton killing, on the one hand, caused a substantial reduction in animals, on the other hand also caused the animals to human hostile, to some extent destroy the animals with human friendly relationship. In fact, for a long time, the behavior of the human animal cruelty has not rested, eat eat peacock, owls, monkey, red-crowned cranes, bear bile absorption, is really to the point of "all things" entrance! What do you want to, so can not cause animal angry? How can you make animals not to stand up and fought back? This is also the animal attack humans, even damage the important reason of human life.
Second, with the progress of human society, some bad behaviors of human beings, not only destroyed the earths environment, and damage to the animals living environment. Factory sewage, automobile exhaust, deforestation of forests and other bad behavior, have caused serious damage to nature, and at the same time there are opposite to the nature of the direct damage caused by animals that makes the animal difficult to live, the type and quantity less and less, destroy the balance of the ecosystem, eventually make human to destruction.
Visible, the relationship between animals and humans have come to the point where serious deterioration, at the same time, also pose a threat to the survival of mankind itself. Humans are still can such wrong-headed, impenitence? ! I think that human beings should be timely change their bad habits, to love animals, protect earths environment.
As a primary school student, we should start from me, start from now, to take care of our nature, protect the animals around us.
Let us act together, take care of animals, people for the ethical treatment of animals, and become a good friend of animals, to improve the relationship between the animals and humans to make their due contribution!
动物是人类的朋友。动物离不开人类，同样，人类也离不开动物。
很久很久以前，动物和人类是一对好朋友。他们互相帮助、互相依靠、和睦相处，谁也离不开谁。但是，随着时间的推移，由于人类自身的原因，造成了动物与人类的关系恶化，而且有越来越严重的趋势。
首先，人类对动物的肆意捕杀，一方面造成了动物的大量减少，另一方面也造成了动物对人类的敌意不断增强，一定程度上破坏了动物与人类的友好关系。事实上，一直以来，人类残害动物的行为一直没有停息过，吃孔雀、吃猫头鹰、吃猴脑、吃丹顶鹤、吸熊胆，真是到了“万物皆入口”的地步!您想，这样怎么能不引起动物的愤怒呢?怎么能让动物不挺身而出、奋起反击呢?这也是造成了动物攻击人类、甚至伤害人类生命的重要原因。
其次，随着人类社会的不断进步，人类自身的一些不良行为，不仅破坏了地球环境，也破坏到了动物的生存环境。工厂的污水、汽车的尾气、对森林的过度砍伐等不良行为，都对大自然造成了严重的破坏，同时也对生存在大自然的动物造成了直接的伤害，使动物生存艰难，种类、数量越来越少，破坏了整个生态系统的平衡，最终使人类走向灭亡。
可见，动物与人类的关系已经到了严重恶化的地步，同时，也威胁到了人类自身的生存。人类难道还能这样执迷不悟、不知悔改吗?!我想，人类应该及时改变自身的不良习惯，爱护动物，保护地球环境。
作为一名小学生，我们应该从我做起，从现在做起，爱护我们的大自然，保护我们周围的动物。
让我们大家一起行动起来，爱护动物，善待动物，成为动物的好朋友，为改善动物与人类的关系做出自己应有的贡献吧!

篇10：保护野生动物倡议书
全文共 1362 字
+ 加入清单地球上的居民们：你们好!
据有幸飞上太空的宇航员介绍，他们在天际遨游时遥望地球，映入眼帘的是一个晶莹的球体，上面蓝色和白色的纹痕相互交错，周围裹着一层薄薄的水蓝色的“纱衣”。
但是，地球上的居民们却不曾知道这个美丽壮观的星球，正遭受着怎样的破坏和严重的威胁。
据资料统计，地球上有23%的耕地受到破坏。有许多哺乳类动物和鸟类濒临灭绝，四分之一的人因此得了各种疾病。所以，保护动物是很重要的。现在有许多动物在一瞬间就会奇迹般消失，这都是因为人们平时的行为造成的。所以保护动物就要从身边的一点一滴做起。近些年，一些不法商贩为了达到自己的经济利益，大肆捕杀动物，造成动物的食物链中断，动物之间的生态失去了平衡，有些动物开始寻找新的食物链，人类就成了它们生存下去的牺牲品。没有了动物，植物的食物链也遭到破坏，人类的食物链也会中断，长此以往，就构成地球上的恶性循环，降临在动物身上的命运终究会降临在人类身上。要知道，家园只有一个，地球不能克隆!
醒悟吧!地球上的居民们，让我们携起手来，用行动保卫家园，用热血浇灌地球。保护人类的朋友——最无辜的小动物，创造最和谐的动物家园，让世界的角角落落每一天都生机勃勃，焕发光彩，充满活力!
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。
相信我们一点点的爱心和所做的这些简单的事情，就能够让那些还在外面流浪的小动物们重新获得一个温暖的家。

篇12：环境保护措施英语作文
全文共 1289 字
+ 加入清单To Whom It May Concern,
I am writing to express my opinion about the current policy on the official holidays, such as Spring Festival and Golden Week Holiday. As you might know, some believe it is a good idea to enjoy a week-long break. For one thing, it provides enough time for people to refresh their minds and thus to have better preparations for their future work. For another, it will lead to increased tourism and in turn stimulate the development of the local economy.
Truly, the past decade has witnessed many advantages of the official holidays, but we should never ignore its disadvantages. On the one hand, it may lead to heavy traffic in that a large number of tourists go on traveling during the same Period, thus, it might cause air pollution. On the other hand, some tourists, with no awareness of environmental protection, often drop litter at random so that the scenic spots are polluted and thus it demands a tremendous sum of money to eliminate the pollution.
Considering the current grim situation, it is necessary that the authorities concerned should take immediate measures to eliminate these disadvantages. Only through these efforts can we relieve the traffic pressure and at the same time raise people’s awareness of environmental protection.
Yours sincerely,
Li Ming
篇13：写濒临危机动物的英语作文北极熊
全文共 3755 字
+ 加入清单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。
篇14：传统建筑保护英语作文
全文共 1612 字
+ 加入清单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.

Many people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our environment.Though the environment doesnt have a mouth to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result, the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!What we are suffering is only a small part of what the nature once suffered. If we dont take action to show respect to the environment.
Measures should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.
Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves. 保护环境初三英语作文（二）

Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks.

When the waste gas from cars is released, the air is polluted. People breathing in the polluted air can develop respiratory disease. Another factor is that people throw their garbage everywhere. All kinds of garbage not only spoil the splendid environment, but also cause environmental pollution. Whats more, industrial pollution also deserves our attention. Wastewater from factories is poured into rivers and this causes water pollution. As a consequence, the greenhouse effect becomes a problem which needs our immediate caution and how to solve is urgent all over the world. At present, some measures have been taken to prevernt.
For example, people classify the garbage and some is recycled after being collected. People are also encouraged to use paper products instead of plastic products because we know that our living condition will be worse if we keep ignoring this problem. And I believe we can prevent pollution if everyone makes the efforts.

篇16：保护动物，珍爱生命
全文共 607 字
+ 加入清单今天，天气晴朗，阳光明媚，爸爸、姐姐和我兴高采烈地来到市博物馆。那里人山人海，热闹非凡，我们一进去就看得眼花缭乱。
瞧!这里有许多动物标本。有又瘦又长的黄鼠狼，它好像发现前方有猎物似的，正一个劲地向前冲呢!还有几百岁的玳瑁，它的样子很像海龟，圆圆的眼睛镶嵌在椭圆形的脸上，正自由自在地在水里游呢!还有刺猬，它身上的刺，又尖又细，嘴巴翘得高高的，神气极了!它们个个活灵活现，栩栩如生。
这里，我还看到各种各样的贝壳和海螺。我最喜欢的是耳朵螺，它长得很像人的耳朵，是咖啡色的，你见过咖啡色的耳朵吗?真有趣!还有珍珠母贝，它大大的，像一个大蜗牛背上的壳一样，不一样的是里面会发出五颜六色的光芒，美丽极了!
令我印象更深的是，这里还有许多远古的化石，如：白票、狼鳍鱼……，真可惜，谁着地球的变迁，不少生物我们再也看不到了，只有这一块块冰凉的石头。
标本和化石，记忆着动物朋友们生命的迹印，一个个鲜活的生命就这样永远永远地从地球上消失了。同时，人类还在不断地制造灾难，滥捕滥杀，与动物争夺生存空间，许多动物频临灭绝的边缘，如不加以保护，人类自身也将面临同样的命运。
这里我要呼吁人们，放下你们的猎枪，让动物们能自由自在地生活，放下你们手中的斧头，给动物们一个美丽的家园，那些冒着浓烟、排着黑水的工厂啊，快停止吧，鸟儿想看到蓝蓝的天空，鱼儿需要清澈的河水，人们啊，一定要爱我们的家园，要保护自然环境，保护野生动物，做到人与动物和谐相处。

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.

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。

+ 加入清单今天下午，我打开电脑上了qq，在qq空间里看见了“惊天地泣鬼神”的一幕。
一些人准备取小熊的胆汁，这时，一只母熊挣脱了铁笼，用巨大的熊掌掐死了小熊，然后把头撞上墙壁，死了。也许这是它们最好它们的办法，因为它们解脱了。
看完这一则故事，我快哭了。这么可爱的小熊，这么伟大的母熊，是谁狠心夺走了它们的生命?是人类。口口声声说保护大熊猫的是谁?也是人类。这不是自相矛盾吗?大熊猫是我国的国宝，可一些熊猫看见人类就想逃。这是为什么?因为有人伤害熊猫。
熊猫是多么可爱啊!他们也有生命，它们不是致富的工具。我们一定要保护熊猫，一些熊猫已找到，还有一些熊猫还在受那无尽的痛苦折磨。我们要将心比心，假如自己是它们，受到这种痛苦会怎么样?
在这里，我呼吁大家：爱护动物，让动物不再惧怕我们，让这个世界变得真正和平吧!
同时我也奉劝那些伤害熊猫的人：熊猫也有生命，熊猫也有感情。它们的价值并不是让我们赚钱，而是为自己而活。希望你们能到此收手!
