水,是生命之源,人要是没有了水就等于没有了生命。我的家乡原本有一条清澈见底的小河,那时候,有许多村民们都那里洗衣服,小孩子也到那里去玩,水里也生活着小鱼,小虾之类的。
小鱼在水里嬉戏,小虾“跑”的可快了,你一不留神就会“飞”的远远的。青蛙也在河里欢快的叫着,好像在骄傲地说着:“我生活的小河最干净,最清澈,没有哪条小河能比的上了。”河边还有几棵大樟树,大樟树仿佛带着微笑的脸说:“我能长那么高,那么大,可都靠小河里的清澈又卫生的水啊、过了几年,小河被污染了,这是因为人们见扔垃圾的地方太远,懒得走过去扔,他们说:“那里太远了,还不如扔在家门口的小河里呢。”日子一天天过去,小河渐渐变得浑浊,变得很臭,小河边也有很多垃圾,人们还把污水排进小河里,河里的小鱼、小虾不像以前那么欢快了,而且渐渐开始大死亡,河边的樟树也开始干枯了,空气不新鲜了,小青蛙在河里发出悲惨的叫声,好像在说:“有家难回,这些人类太不爱护环境了。”我们做一个领头,保护水资源,从我做起,多为别人担心一点,不管是人还是动物。都要为别人着想。
从上表可以看出,三条河水质污染严重,三条河水质较好,究其原因,我们发现主要和河道所处的环境有关:前三条河处于密集的居民区中,且和后面的工业区较近,而后三条河相对来说远离居民区和工业区。不可否认,河道水质的污染,基本都是人为造成的。
古人云:勿以善小而不为,勿以恶小而为之。河边的'有些居民养成了一种陋习,就是爱随意把垃圾扔到江河湖泊里或其他不适宜的地方,图一时之便利。试想一下,如果我们每一个人都往江河湖泊里扔垃圾,那么,我们赖以生存的水资源就会被迅速污染;如果大量的水资源遭到污染,我们又怎么生存下去呢?
一些工厂不注意环保,把工业废水排入江河湖泊,造成了许多江河湖泊的污染。这会带来什么后果呢?鱼虾喝了这样的水,立刻就会死去;人类如果用这样的水洗澡,很容易诱发各种疾病;人类如果喝了这样的水,那问题更加严重。这些被污染的水吞噬着人类和动植物的健康!试想,就算工厂的员工赚了很多的钱,水却被污染了,那么人们没有清洁的水可喝,那时候要这么多钱又有什么用呢?这是多么损人不利己的行为呀!
觉醒吧,家乡的人们,别为了图一时之便,而遭一生之害!有数据表明,全世界范围内,每年因喝了不干净的水而死亡的儿童就有5000万人!这数字是多么令人怵目惊心!水,已经向人类敲响了警钟!
亡羊补牢,为时不晚。为了我们的家乡天蓝地绿水长清,为了我们的人民更健康,人人充满青春的活力,我们每个人都要行动起来,认识到保护水资源的重要性,养成节约用水的好习惯。只要我们警钟长鸣,代代保持忧患意识,相信大自然所馈赠给我们的宝贵财富——水,会不断给我们创造更加美好的生活!
Giant Panda is our national treasure, the state can be said for the protection of giant pandas put a lot of human and material resources giant now has been the world's people the protection and care, which is a good thing, of course, the Tibetan antelope as the country's animal protection , The National People have been recognized, however, this tiger? The poor will be extinct Siberian tiger who is going to have a genuine concern and care a little bit?
According to statistics, the Siberian tiger left at present, less than 20, still such a small number of these survive, has had imagined. Two years ago, in the mountains of Huanren, Liaoning found to be a man to die under the presentation of the Siberian tiger, from this we can see that the above countries and the people of the importance we attach to it, this first Manchurian tiger is actually how the dead do not Conclusion, and the other is only from the northeast where hu came to the place where the wonder and the third is the matter did not rise to the national media in particular. This really puzzled the other person you! Is it really the other tiger who fear love is not worth it, it really fate of the Siberian tiger so?
Towering mountains should not unique to human beings, should not have dense forest unique to human beings, rivers clear this should not be unique to human beings, the Siberian tiger survival of this nature should not be unique to human beings. Siberian tiger to the left of a piece of heaven and earth to survive it, the High IQ is the human species, there are still ways to leave that piece of local survival, and the tiger have to leave that piece of the local dead; you save tigers, is the human population control, engage in Family planning, and the Siberian tiger is scarce Rending it! Now we can hear the cries of tigers in the future even the Siberian tiger can be heard the cries.
A tiger is a kind of catamount animal. It looks like a cat, but much bigger than a cat. A tiger is very ferocious and it eats mainly meat. It has yellow and black streaks all over its body and it looks very beautiful. Its tail is long and strong and it can hit its quarry dying.
Tigers live in the thick forests and small animals in the forests are tigers' food.
During the past years, many forests have been cut down and the living conditions of the tigers are becoming worse and worse. There are fewer tigers left in the world now. Tigers are the animals of the world, and they should have their own living spaces. We must do our best to protect the tigers and their living environment.
