With human beings on Earth since then, we continue to evolve at the same time has been hurt those lovely animals. They did not at fault, they are only in accordance with the laws of nature live in peace. But since the existence of mankind , their homes become increasingly small. Some animals have even become extinct.
In the extinction of animal, the thylacine is the worst. Thylacine in a long time ago to live in the vast prairie, they have been very happy, carefree. Since the arrival of human beings have changed their lives. Due to the large number of human enclosure, livestock grass makes less and less change to many herbivores to move to other grasslands. This herbivorous animals to eat the wolf bag, there is no food. They steal human animals. Farmers would hate the wolf from the bag, see a killing one, on this last one wild thylacine was also killed. When people should be aware of extinct thylacine, the protection of the park began last a thylacine, it thylacine only 48 days before the final days. And 48 days later, the Forever thylacine disappeared from the Earth, the Forever!
Of course, not all animals are extinct human killing, some changes in the environment are not suited extinction. However, the extinction of some animals, human beings have an unshirkable responsibility. Since ancient times human beings have been cruel to those animals alone, human deprivation of their right to live.
Now seems to have been aware of the extinction of an animal hazards. In order to make money, what people are willing to do so, they sell fur animals, shopping malls, the meat of animals sold to restaurants. But we can not shirk all responsibility to the heads of traders, consumers also have the responsibility, if there is no consumer demand then the traders will not take the risk. Human beings are still eating wild animals. For example: the snake. If the extinction of the snakes, rats would wantonly breeding, then how do we ... ...
So each has its biological significance of the existence, they are in the natural law of survival. If a broken food chain, then another will wantonly breeding animals, and even a threat to humanity, we bear in mind the protection of animals. The protection of animals is to protect human beings themselves!
参考译文：
自从地球上有了人类以后,我们在不断地发展进化的同时也在不断的伤害着那些可爱的动物们.他们没有过错,他们只是根据自然界的法则和平的生活着.可是自从有了人类的存在,他们的家园变的越来越小.有些动物甚至已经灭绝了.
在灭绝的动物里,袋狼算是最惨的了.在很久以前袋狼生活在广阔的大草原上,它们过的很快活,无忧无虑.自从人类的到来改变了它们的生活.由于人类的大量圈地,饲养牲畜使得绿草变地越来越少,许多食草动物迁徙到别的草原上.这样以草食性动物为食的袋狼就没有了食物.它们便去偷人类饲养的动物.农场主便痛恨起了袋狼,见一个杀一个,就这样最后一只野生袋狼也被杀死了.当人们意识到袋狼就要灭绝时,才开始保护公园里的最后一只袋狼,这只袋狼才过了最后48天的好日子.而48天后,袋狼永远的从地球上消失了,永远的!
当然不是所有灭绝的动物都是人类杀死,有的是不适应环境的变化而灭绝的.但是某些动物的灭绝,人类有着不可推卸的责任.人类自古以来就一直残忍地对待着那些动物们,人类剥夺了它们生活的权利.
现在人们似乎还没有意识到一种动物的灭绝的危害.为了赚钱人什么都愿意做,他们把动物的皮毛卖到商场,把动物的肉卖到餐馆.但是我们不能把一切责任都推卸到商贩的头上,消费者也有责任,如果没有消费者的需求那么商贩也不会铤而走险.人类还在吃着野生动物.比如：蛇.如果蛇灭绝了,老鼠会大肆繁殖,到那时候我们该怎么办……
因此每一种生物都有它存在的意义,它们都在以自然的法则生存.如果生物链的一头断了,那么另一种动物就会大肆繁殖,甚至威胁到人类,大家记住保护动物.保护动物就是保护人类自己!

参考译文：
地球上的人类和许多动物都是地球母亲的儿女.地球好似一驾遨游太空的宇宙飞船,人类与许多动物共处在这个生态环境中.可我们人类占着自己高大、聪明,任意破坏动物们的居住环境,让它们无从生存.于是“珍惜地球,爱护动物”一时成了最热门的话题.
保护动物,是我们人人都要做到的,许多人任意去猎杀动物,虽然现在的人都说要保护动物,但是还有很多顽固的人不听,继续猎杀动物,人类拿动物来观赏、卖钱,用兽皮做大衣……但你们有没有想过,如果你是一只动物,却遭到了人类的猎杀,你会怎么想,你愿意吗,你愿意被猎杀吗?你绝对不愿意,有些人说：“我又不是动物.”但你们有没有想过动物们会怎么想吗?现在人类大量捕杀动物,动物会甘心吗?不,不会,永远不会.它们不愿意死在人类手里.它们愿意被你们猎杀吗?不,它们有一千个不愿意,一万个不愿意,一亿个不愿意……
有些人虽然知道怎样去爱护动物,可是他们只会假惺惺地去教育别人,而自己却照样破坏环境,照样兴致勃勃品尝野味. 就拿印度洋毛里求斯群岛上生活的渡渡鸟来说,由于它身上的肉鲜美无比,所以遭到当时人类的大量捕食,在十七世纪就已告灭绝.但是如果当时人们有动物保护意识的话,就不会造成渡渡鸟的灭绝.
还有鲸,鲸不是让你们随意捕杀的,鲸是被杀掉一头就死一头的,不像小鱼小虾那样多,如果我们把鲸杀掉了,那我们的子孙后代,他们不是看不到鲸这种动物吗?
现在,有些动物已经灭绝了,鳄鱼虽然凶猛,但人类更凶猛.就是因为有些动物身上的器官具有突出的经济价值,由此成为被人类掠夺利用的对象,成为动物灭绝的主要因素.鳄鱼长着锐利的牙齿,和硕大的食物胃口,我们都说鳄鱼可怕,但鳄鱼更怕人类,在人类的眼中,鳄鱼皮可以制成行李箱,手提包,钱包,鞋等物品,所以鳄鱼,现在已经成为快要灭绝的动物了.
《金色的脚印》,这篇文章讲了正太郎家捉来了一只小狐狸,两只老狐狸想尽办法就救出小狐狸,正太郎很同情小狐狸,他偷偷地给老狐狸投送食物,于是,他们之间建立了亲密,信任的关系,后来两只老狐狸救了正太郎,最后,小狐狸回归了大自然,两只老狐狸是多么高兴!这篇文章赞美了人与动物之间互相信任,互相帮助,和谐相处的美好关系,也展现了动物之间的浓浓亲情.我们就要向正太郎学习,他帮助动物,动物也救了他,这样不是很好么?为什么人们还是要捕杀动物呢?
在此,我呼吁人们,不要再破坏自然界中的花草树木,不要再乱杀一禽一兽,不要再杀害我们的朋友,要保护好自然界中的一个个生灵.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.
朋友们,动物是大自然留给人类的无价之宝,它是我们人类的朋友.它们的生衍死灭与我们人类的生活是密切相关的.动物的大量毁灭对人类将产生严重的不良后果,造成生态严重不平衡,从而使人类的生存环境遭到破坏.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!
