保护野生动物,共建和平家园作文

老虎是生活在食物链顶端的一种动物,它关系到整个生物链的平衡。因此,保护老虎不单单是保护老虎这么一个物种的问题,而是保护整个食物链完整性的问题。

目前分布于我国的四个老虎亚种(东北虎、华南虎、孟加拉虎和印支虎)中,惟有华南虎是中国独有的。19世纪以前,华南虎曾经广泛分布于以我国东南部为主的国内广大地区。20世纪后,由于自然环境变迁、战乱纷扰及人类活动影响等多方面的原因,华南虎的分布区域不断受到挤压,分布地域面积逐渐缩校直至上个世纪80年代以前,由于捕猎和砍伐森林等活动,使华南虎赖以生存的栖息地受到破坏,华南虎的数量急剧减少。

据以往调查估算,目前中国处于野生状态的华南虎仅有20至30只,养殖在中国动物园里的数量也仅有60只,这仪数量比大熊猫还要稀少。在最近的一次野外考察中,甚至没有发现活的野生华南虎个体,华南虎已接近物种灭绝的边缘。

国家林业局全国野生动植物研究与发展中心的副研究员陆军介绍说,由于动物园中的数量有限,用于交配的华南虎之间的血缘关系越来越亲近,目前有的新产虎崽已经开始出现短尾(尾巴短一结)的现象。毫无疑问,如果任由这一趋势发展下去,在不久的将来,这一世界最濒危动物将不复存在。

透过虎类这一典型的例子,我们更应该保护动物,从自己做起,从他人做起,从身边的小事做起。让我们行动起来保护野生动物,共建和平家园世界将变得更美好。

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.

一日三餐,都要吃东西,而肉则是必不可少的,我们吃的大多数都是鸡鸭鱼肉,这些没啥大不了。可是一些珍稀动物也被摆上了餐桌,如鳄鱼,江豚,鲸等。

我们都是地球妈妈的孩子,又何必要向兄弟姐妹下此毒手呢?

其实大自然是一个相当复杂的食物链,里面的生物可谓缺一不可。缺了其中的任何一种都会早产极大的后果,就会乱了套。在此就举几个例子吧:

蛇,众所周知蛇是无足的爬行动物的总称目前全球共有3000多种蛇类。身体细长,四肢退化,无可活动的眼睑,无耳孔,无四肢,无前肢带,身体表面覆盖有鳞。部分有毒,但大多数无毒。蛇类中最毒的要数大洋洲的太攀蛇和内陆太攀蛇。它每咬一口释出的毒液已足够杀死100个成年人,最长的蛇要属网斑蟒它。

是人们知道的唯一体长达10米的蟒蛇。网斑蟒通常生活在热带的亚洲地区,依靠身体的重量缠死猎物,眼镜王蛇也应是大家较为熟悉的一种,是最长的毒蛇,喜欢捕食蛇。你们知道吗,在一些地方蛇已经成为了保护动物。你们知道吗蛇的毒液已被用来治疗一些不治之症。而且可以成为史上最强的麻醉剂。

再说鳄鱼。鳄鱼是迄今发现活着的最早和最原始的动物之一,它是在三叠纪至白垩纪的中生代( 约两亿年以前)由两栖类进化而来,延续至今仍是半水生且性情凶猛的爬行动物,它和恐龙是同时代的动物,恐龙的灭绝不管是环境的影响,还是自身的原因,都已是化石;鳄鱼的存在证明它更加强盛的生命力。

被誉为活化石的他们已经越来越无法适应当前的环境了,仅存的23种中,有17大概种处在濒危状态鳄鱼全身都是宝,他们的皮可以做为鳄皮大衣,肉可以做成汤, 血清提取出来的胎蛋白将成为史上最强大的抗生素,甚至可以抗击艾滋病。这可谓是一项重大成功的发现。

啊!

朋友们,动物的大量毁灭对人类将产生严重的不良后果,造成生态环境严重不平衡,从而使人类的生存环境遭到破坏。消灭动物,就是在消灭人类自己,如果有一天世界上的动物全都消失了,那人类还能生存吗?要保护动物,珍惜这自然界里的每一个生灵吧!

让我们从现在做起,从我做起,保护动物,使世界变得更美好吧!保护动物,就是保护人类自己。

Humans have only one earth, it is human beings rely on natural resources, people want to live a happy happy life, you must consciously to protect the natural environment, care for the earth.

However, in recent years, the earths environment is more and more bad: global warming, hurricane, heavy rain, such as frequent disastrous weather, infectious diseases such as SARS, bird flu, bring serious threat to human life and work and a lot of inconvenience. These are the people constantly "damage" the result of the earth. Large forests have been cut down, green green hill was digging, beautiful grassland into desert, the clear river water turbidity. Trees less, castle peak bald, grassland drought, water dark and make people living environment deteriorate, breathe the air, living environment "occupied" by many harmful things, the virus will take into the body of people, we human beings will suffer from some terrible diseases.

A few days ago, I read in the newspaper that a cartoon: a man sitting on a tree, is he sitting on the branch. "Hum, really funny." Some people may think so. Dont you have to think of it, this is just a funny cartoon? It is just in our? Dont you see, it is warning us: human in the damage to the environment at the same time, also in imperceptible to hurt yourself.

When you walk in the street, if you want to spit, what would you do? If you chose to spit on the ground, you ever think that you hurt yourself? Phlegmy contains a lot of bacteria, when the sun will reproduce and spread. Also, when you cut down a tree, when you cut a piece of grass, when you pour the dirt into rivers, dont you think it is in the destruction of the environment, "injury"?

Proverb is well said: ", predecessors trees descendants cool, "predecessors gave us large tracts of forest and green space, we leave behind is what? Is bare desert, or the thick forest, you must choose the dense woods. What hesitate, let us together voluntarily protect the environment, good care environment, consciously consciously afforest environment, improve our living environment, create a better future!

人类只有一个地球,它是人类赖以生存的自然资源,人们要过上幸福美好的生活,就必须自觉地保护自然环境,爱护地球。

然而,近几年来,地球的环境却越来越恶劣:全球性气候变暖,飓风、暴雨等灾害性天气频繁出现,“非典”、禽流感等传染性疾病时有发生,给人类的生活和工作带来严重威胁和许多不便。这些都是人们不断地“伤害”地球的结果。大片的森林被砍伐,碧绿的青山被挖掘,美丽的草原成荒漠,清澈的河水成浊流。树林少了,青山秃了,草原荒了,清水黑了,使人们生存的环境变坏,呼吸的空气变差,生活的环境被许多有害的东西所“侵占”,病毒就趁机钻进人们的体内,我们人类就会患上一些可怕的疾病。

前几天,我在报纸上看到这样一幅漫画:一个人坐在树梢上,正在砍他坐着的那根树枝。“哼,真好笑。”有些人可能会这么想。难道你就没有想一想,这仅仅是幅好笑的漫画吗?它不正是在讽刺我们吗?难道你就没有悟到,它在警告我们:人类在破坏环境的同时,也在不知不觉地伤害自己。

当你走在大街上,如果你想吐痰,你会怎么做呢?如果你选择了吐在地上,那么你想过没有,你在害自己吗?一口痰含有大量的病菌,当太阳着时就会繁殖、传染。同样,当你砍伐一棵树,当你挖掉一片草,当你把脏物倒进河流,难道你没有觉得这是在破坏环境,“伤害”自己吗?

俗语说得好:“前人栽树,后人乘凉”,前人给了我们大片大片的森林,绿地,我们留给后人的是什么?是光秃秃的荒漠,还是茂密的树林,你肯定选择的是茂密的树林。那还有什么犹豫的,让我们大家一起自觉保护环境,自觉爱护环境,自觉绿化环境,改善我们的生活环境,创造美好的未来!

Now our side, however, the environment is worsening, I once saw a man on the side of the road just lost a piece of paper, I was very sad, think if everyone throw a piece of paper, then the world will be what are the consequences? Is terrible, and the world will become a white tips, more think more terrible, I quickly pick up the pieces of paper, thrown into the garbage can. At another time, I saw on TV a report about the environment: fujian on the other side of the river water turbidity is not clear, the fish died in the river, floating in the river every fish mouth blowing, the river still waving white trash, have small bags, candy. The scene is really horrible. Improvement in living standards of people, and their environmental protection consciousness is on the decline.

I believe that as long as we work together, in the near future, our environment will be getting better and better.

环境对于我们来说,是非常重要的,它就像一把大伞,为我们遮风挡雨保护我们的家园,如果离开了这把神奇的伞,那我们的家园就会像撒哈拉大沙漠一样,一片死气沉沉,荒无人烟。所以我要向全球发出意示,让我们一起保护环境吧!

然而现在我们身边,环境越来越恶化,有一次我看见一个大人在路边随便丢了一张纸,我非常伤心,心想如果每个人都丢一张废纸,那么这个世界会是什么后果呢?真是太可怕了,整个世界就会变成白色的垃圾站,越想越可怕,我急忙把这个纸片捡起来,丢进垃圾桶里。还有一次,我在电视上看见一篇有关环境的报道:福建那边的江水浑浊不清,江里的鱼都死了,浮在了江面,每条鱼的嘴里都吐着白沫,江边还飘着白色垃圾,有小食品袋,糖果皮。这一景象真是惨不忍睹。人们的生活水平在提高,自身的环保意识却在下降。还有那些没有道德的伐树者,他们可有想过树给我们带来的好处呢?树为我们人类付出了那么多!那么多树为我们挡住袭来的沙尘暴和可怕的龙卷风,这些伐树者真应该静静的好好的反省一下,如果没有了树,我们的生活环境又是什么样子呢?可见目前我们环境的恶劣,也是在向我们发出了警告,提醒我们爱护环境刻不容缓!我认为爱护环境,人人有责,所以我们要从现在做起,从身边做起,不要随地吐痰,不乱丢纸屑,少用本子,用完的本子可以当验算本,看完的报纸可以练习毛笔字。把保护环境当做最重要的工作做下去,树立环保意识,做环保守护者。

“保护环境,人人有责。”我要把这句话铭记在心,把这句话当作一颗种子,我会用细心去浇灌它,让它茁壮成长,让“爱护环境,人人有责”这句话传递下去。我相信,只要我们齐心协力,在不久的将来,我们周围的环境一定会变得越来越好。

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.

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.

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!

有许多人因为能挣钱就随便捕捉青蛙,青蛙体大肉肥,味道鲜美而且还非常有营养,就有人到市场上卖,我感到非常痛心,我也无能为力,只好默默的为青蛙祝福。

青蛙被称为“除害高手”青蛙的又叫田鸡,蛙类大约有4800种,绝大部分生活在水中,也有生活在雨林潮湿环境的树上的。卵产于水中,青蛙是卵生的,卵孵化成蝌蚪,蝌蚪在水里也能捉害虫,等的卵都在水里,一只蝌蚪每天要吃掉100多只孑孓,最后才变成青蛙。它可以捕捉害虫,蚊子、苍蝇、小飞蛾、蝗虫、蝼蛄、椿象、蝇类及稻飞虱等农业害虫为主要食物。都可以吃。在南方有许多人捕捉青蛙,在北方就少一些。一只青蛙一分钟能吃10只,一只青蛙一天捕食的害虫,少则五六十只,多则二百只,如此推算,一只青蛙一年至少要吃掉15000只。因此,青蛙是当之无愧的农田卫士。

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!

篇20:高一保护动物的语文作文

全文共 629 字

唉,现在的人们啊,真是越来越不懂的珍惜了。

下午,我正在和妈妈说话呢,突然,姑姑走了进来,还把我的侄子和侄女给带来了,手上有一只鸟,好像是大伯抓的。

“有没有带子?”

“有,在那里。”

说到这里,我就已经猜到姑姑要做什么事情了,肯定是要把小鸟的腿给扎起来,不过后面就不知道要干什么了,说不定还会烧着吃掉呢。果不其然,姑姑抓住小鸟的一只脚,绑了起来,然后把袋子的另一端递到侄子的手里,带着他就出去了,在我家门口玩了起来。

不会吧,居然捉小鸟用来玩耍,天呀,这是什么节奏,我最看不惯了,这些关于伤害小动物们的事情对我来说是特别特别的严重的,因为我经常看一些关于动物之类的书,所以觉得对于动物,它们还是十分可爱的,不要再伤害他们,要不然会破坏生物链的。我看着那麻雀不断的在挣扎着想要飞起来,翅膀一扑一扑的,可是根本就没有什么用,我就奇怪了,明明它是可以飞起来的,小孩子的力气是没有那么大的,要是飞起来根本就拽不住的,可能是被剪掉了翅膀吧。不过呢,我现在只能希望他们能把小鸟给放掉,不过就算这样,能活下来的几率是很小的。再看看这四周,都没有什么鸟了,连一个影子都看不到,也是,现在的环境越来越差了,而又由于我们人类的原因,有的动物都快要面临这灭绝的危险了。“哈哈哈……”我的耳边传来一阵阵笑声,转过头来看着我的小侄子,在那儿看着麻雀不停的傻笑着,开心的不得了,一蹦一跳的,把麻雀在地上拖来拖去,姑姑也跟着他一块笑,麻雀真无辜啊。

希望人们以后能保护动物吧,不要等失去了再来珍惜。
