Nature has given us everything, and our food and clothing cant live without it, so we should be grateful and look at nature with gratitude.

Gratitude it contains tolerance, but some people dont know the tolerance of natural, they only know by deforestation and killing of wild animals, only know to claim from the nature, but never written for nature to do what. The ancients of our country knew "the grace of the water of the people". But we still dont understand the true meaning of this sentence. When nature retaliates against us, we complain of nature and blame nature instead of tolerance. To know that nature hurts us much less than we do to it. The harm we suffer is nothing compared to the harm done to nature. Moreover, we have gained a lot from nature, and do not blame nature, let us treat nature with gratitude.

When the rising sun rises from the east, it brings light and warmth to us. He has never been stingy with what he has, giving us everything he has, like our selfless parents, who give their best to their children and never think of themselves.

When the rain falls on the earth, it moistens everything, gives birth to life, and gives the most sincere heart to people. It washes away the dirt from all things, and never complains that it is getting dirty. It is like the teacher who imparts knowledge, the hard work nourishes us, enables us to thrive without taking into account the dissipation of our energy.

When a breeze blows past you, it lifts the heat of the summer, and pays nothing in return. It always offers its most tender side to people, never to blame people easily. It is like an encouraging look in the distance, and when you fail, you touch your tired heart silently.

When a severe thunder comes, it seems to be a stern voice to your admonition, which may sound surprising, but it inspires and reminds you.

But now, the environment has been destroyed. The morning sun is not so soft; The rain is no longer pure; The breeze becomes violent and the air quality drops; The water became cloudy, even the atmosphere was empty, and the intense ultraviolet radiation hit the earth. Everything began to dry up and the environment began to deteriorate. Why is that? This is because humans do not appreciate gratitude, and do not appreciate nature. They keep taking away from nature, and impoverish the rich; To change the nature of goodness; To make the beauty of nature ugly. Now "blue sky white clouds float, white clouds under the horse run." The scene is gone, except that the smoke of the factory is dancing in the air to kill the chirping of birds. The effluent effluent flowing into the otherwise clean river has been able to extinguish the game of shrimp under the fish. Instead, the noisy sonatas of cars, the roaring symphony of factories... So nature is taking revenge on us, and in recent years, natural disasters have taken the lives of our loved ones, and we have suffered from the loss of our relatives. Its all because people dont appreciate nature and change nature, so now were going to save it and save ourselves, and the way to save it is to be grateful. Only every one have a grateful heart, to understand, to understand the true meaning of love, if we live in a world full of gratitude, full of love, then our life will be more beautiful, the sky will be more blue, pure, vast.

Let us be thankful for nature and love nature with our hearts so that we can live in harmony with nature.

篇1:环境污染作文600字

全文共 1572 字

如果说保护环境、保护动物、节约能源这些环保理念已成行为准则,低碳生活则更是我们急需建立的绿色生活方式。

保护环境作文600字一:

随着人口地迅速增长,工农业迅速发展,生态环境的污染也随之而来。工厂排放的污水、废气、产生的固体废物,人们乱砍滥伐,日常生活中环境保护意识淡薄,从而使到环境逐渐恶化,生态资源不能再生,并给人类带来了一系列的灾难。

伴随着人类社会的高度发展,人类已经进入了空前的文明时代。我们应该生活在优美的环境中,但事实上我们感受到的却是窒息的环境。光秃的山坡、发黑的河水、枯萎的草地??

每次都有人不断的抱怨着环境不好资源不够用,可是那些人有是否想过,自己对绿色世界做过多少贡献?关过几次灯?关过几次水?保护环境,应该从我做起。这对我们每个人来说都很重要,而且对我们每个人的幸福也有很大关系。回顾历史,再看现实,人类的每一次发展,每一次进步,每一次都是要求自然的给予。人类的发展进步,最终得益的总是人类,付出的总是自然。所以作为人类的一分子,我们应该多参加环保活动。多植树,多种花,使我们永远拥有蓝天、白云、碧水、绿地的美丽家园,让我们拥有一颗绿色心情。

提到怎样更深一步做好环保先锋,来保护自己的家园,我认为“低碳”生活是最重要的。

“低碳”生活就是指生活作息时所耗用的能量要尽力减少,从而减低二氧化碳的排放量。低碳生活,对于我们普通人来说是一种态度,而不是能力,我们应该积极提倡并去实践低碳生活,注意节电、节油、节气,从点滴做起。如果说保护环境、保护动物、节约能源这些环保理念已成行为准则,低碳生活则更是我们急需建立的绿色生活方式。

也因此在我认为,气候变化不只是环保主义者、专家学者关心的问题,而是与我们每个人息息相关。如果你觉得你一个人的力量对于整个地球简直是微乎其微,一个人的力量根本无所谓,那就错了。若仔细想想,一只节能灯、一台太阳能热水器能为节能减排做的贡献的确很小,可13亿人中只要有1/10的人使用,那节约的能源、减少的碳排量都将会是天文数字。

由此可见,低碳生活可以让我们的身体更健康,环境更优美,生活质量真正提高。

为了让我们的生活更美好,人们应该互相提倡、互相督促:共创绿色家园,留下绿色心情,从我做起,保护自然、保护环境、保护生态平衡,让我们的家园更美好、更灿烂!

保护环境作文600字二:

大家都知道,如果我们不保护环境,地球上的各种资源都会慢慢枯竭;如果不保护环境,人们就会面临灭亡;如果不保护环境,不仅是人类,地球也会逐渐走向灭亡!我们生活的这个地球是那么美丽、那么可爱,同时又是那么容易破碎。我们经常就可以看到一些这样的镜头:一位高大威猛的执法人员走着走着,“呸”的一声把一口痰吐在了干净的地面上;一位中年男子抽着烟,走了一会儿就把还没熄灭的烟头扔在了地上。我曾经看见过这样一幅画面:一位父亲拉着正喝着酸奶的儿子急匆匆地走,儿子问父亲,瓶子扔哪儿?父亲说随便扔。儿子又说,老师说‘不能随便扔东西!’父亲不耐烦地说,哎呀,特殊情况特殊对待嘛!说着,就把瓶子随手扔在了路边。人们往往乱扔东西时,垃圾箱就在不足十步的地方,他们就不愿多走几步,把不要的东西扔进垃圾桶里。如果每个人都扔一个垃圾,地球就会变成垃圾的海洋。

还有一个镜头,一个母亲给孩子买了一个冰棍,把撕下的纸顺手就扔在了一边。这个孩子看到后,捡了起来,准备扔进不远的垃圾桶,可就在这时,那位母亲赶紧走了上来,拍掉了孩子手上的纸,说:“快扔掉,脏!”同样是地球公民,为什么却有如此之大的反差!如果每个人都捡起身边的垃圾,那么我们的地球将会变得多么漂亮,干净啊!难道那些破坏环境的人要等到环境在他们的破坏下“不堪入目”才回过头来再继续保护环境吗?

同学们,让我们行动起来吧,捡起脚边的垃圾,扔进不远的垃圾桶,让我们的地球母亲重现以前的光彩吧!让我们共同创造一个洁净的家园

Nowadays, motorcycles are popular around us. They have become an important

means of transport in Chinese cities. Compared with the bike and the car, the

motorcycle has its own advantages. First, it is quite flexible. When there is a

traffic jam, it can go through the cars that are held up in the street. Besides,

it doesnt consume much petrol. Most important of all, it can carry another

person at the back. But every coin has two sides. The negative aspects are also

apparent. To begin with, its very complicated to get qualified fur riding a

motorcycle. Youll have to go through a series of procedures to get a riding

license. Furthermore, the maintenance is expensive. Worst of all, it costs a big

sum of money to pay fur the license plate, especially in big cities.

In conclusion, it has both favorable and unfavorable aspects. However, if

the authorities concerned simplify the procedures and reduce the cost of the

license plate, the motorcycle will be accepted by more people.

As we all know, pollution is harmful to living beings. There are many

different types of pollutions in this world. For instance, water pollution, air

pollution, noise pollution and so on. Water pollution cause many kinds of

disease that have negative effects on human beings, sometimes the diseases will

take people’s life away. Dirty air will increase the rate of getting lung

cancer. While the noise pollution will cause insomnia. People’s health condition

will be damaged.

In my humble opinion, people should take measures to control the pollution.

Recently, not only the government, but also individual has taken part in the

action of protecting the environment. This is a good sign. Rivers are being

cleaned, air is purified, and the people come to realize that the importance of

protecting the environment.

However, this is not enough, the problems are still exist. Not all of them

have been solved. Some factories are still pouring dirty water into the rivers

or give off the toxic gas into the sky. We should know that protecting the

environment needs everybody’s effort.

今天,我们一家来水泥厂调查,我们刚到酸枣村坡顶,往下一看,从水泥厂烟囱冒出滚滚浓烟,路旁的草上、花朵上、树叶上、石头上、房顶上全是一层厚厚的灰尘。

再往下走,便来到水泥厂,一股臭气扑面而来,抬头一看,到处尘土飞扬,我们赶紧捂住鼻子只往前走。

我们走了一会儿,来到一户农民家,看见一位姨妈坐在门前,我们上前问到:“姨妈你们这里现在污染大吗?水干净不干净?”姨妈说:“这里污染太大了,以前没有水泥厂的时候,水打来就可以喝,自从有了水泥厂,打来就可以喝的水,现在却变成了臭水,我们现在喝的水是从地底下抽出来的,而且还要进行高温消毒才可以喝”听到这里,我感到很惊讶,原来水泥厂的污染有这么严重。

走了一会儿,我们看见一位老奶,我上前问到:“奶奶,你们桌子一天多少遍?庄稼长得怎样?”老奶奶皱着眉头说:“桌子一天要五六遍,庄稼长得也不好,你们看我家地里的豆苗,像被开水烫过一样,全部都枯萎了,还有我们这里的桔子树,以前长得很茂盛,桔子又大又甜,现在桔子树也全枯萎了,即使有几棵存活下来的,结的桔子又小又苦。我们也多次向上级反映,但不了了之”老奶说完,深深的叹了口气。

听了她们的活,我的心里非常难受,我多么希望这些工厂在生产的过程中,能将排出来的废气和灰尘进行处理,让老百姓有一个更好的生存空间,那该多好呀!

保护环境善待地球

众所周知,我们只有一个地球。地球是我们的家园。我无法想象,如果地球消失了,人类该怎样生存。

我们的生活不能离开地球,所以,请善待地球。

现在的空气不是很新鲜,天也不是那样湛蓝。这是为什么?因为有很多人乱砍滥伐,还污染河流。我们在森林里看不见小动物玩耍,也看不见小鱼在水里游泳。

如果长时间都是这个景象,世界末日就会来临。

那么,我们怎样才能保护环境呢?让我来给大家一些建议吧。

首先,我们可以植树。树木可以给予我们新鲜的空气,还可以吸收二氧化碳。

其次,我们可以坐公交去上学或上班,少开车。汽车排放的尾气会污染空气,它对我们的身体没有好处,对地球也没有好处。

这就是我的建议。

今天是世界环境日,让我们一起保护环境,善待地球吧!

篇13:环境污染原因环境污染的根源

全文共 2362 字

在十年前的中国,大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样,看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产,燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝,随着中国经济的迅速发展,人们生活水平的不断提高,人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题,其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬,专家们各有其立场,但对于普通百姓来说,全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖,海平面上升,冰川融化,动植物灭亡的问题,人们大多数是在电视新闻或报刊杂志上看到,恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题,人们开始关注更多的便是最近发生在北京,广州,武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康,更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象,国外专家学者很多年前便开始研究。

那么何为灰霾?灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物(PM2.5)和臭氧()、二氧化氮()、二氧化硫()、挥发性有机物()等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关,还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种,直径小于2.5微米的颗粒物(PM2.5)和直径小于10微米的颗粒物(PM10)。虽然两种形式的颗粒物都对人类健康有极大的危害,PM2.5被普遍认为是更危险的,因为它的体积小,大约只有人类头发宽度的1/30。人们在呼吸时,PM2.5可以进入人类肺组织深处,甚至进入血液,造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此,PM2.5可以传播的更远,停留在空气的时间越长,影响更大的人口。PM2.5和PM10的主要来源包括机动车,电厂和其他工业源,以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合,可以在城市或农村地区天空一片阴霾,而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因,像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围,当地空气干燥,白天阳光充足。到了晚上,地表面冷却很快。地面附近的空气变冷,而上层空气都比较热,形成逆温。北京市位于华北平原的西北边缘,背靠太行山余脉和燕山山脉,面对辽阔的华北平原,东南距渤海约150公里, 地处暖温带半湿润地区,气候属于暖温带半湿润大陆性季风气候,四季分明,春季多风和沙尘,夏季炎热多雨,秋季晴朗干燥,冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远,周围地形如盆地,集热容易散热难,河湖多、晚上水汽多,城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市,而且城市海拔较低,周围至少有一面是高地,都分布在低于南北纬50度的地方。这些地区夏季阳光明媚,天气温暖干燥。在城市的盆地地区,逆温现象十分普遍。夏季的阳光使地面温度升高,城市街道和建筑物迅速升温,与炎热的物体表面接触的空气温度升高。通过对流空气向上运动,但它却不能穿透逆温层,因为上面的空气温度更暖且密度更小。空气聚集,但连续的对流形成了垂直的循环,使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下,通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集,大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响,学者称它为街谷模型。随着城市化的加速,城市及城市周边的自然生态系统逐渐被人工生态系统取代,取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续,高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时,风速迅速降低并产生特殊的湍流,使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用,因此,对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市,尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物(PM)浓度和40%的二氧化氮(NO2)浓度。因此,通过对植被的合理利用能过创造一个有效的城市污染过滤膜,对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题,相反它是一个长久的问题,从它如何形成,加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象,它只是地球环境污染的一个缩影。我们更应该探究它的根源问题,什么才是它形成的根源,什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题,但我们可以通过减少排放源,通过增加植被,加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼,越来越发达便利的交通,相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了,人们是否会怀念那晴朗的蓝天,向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

We live in the beautiful earth, its a pity that the earth is every day under the various odor, chemical items, poison, carrion, automobile exhaust, living garbage, factories and so on dirty garbage pollution, make our lovely earth gradually degradation. So to protect the environment is the duty of every man.

Plants and trees is human natural oxygen "manufacturer". But the deforestation, the destruction of the ecological balance of nature; Sand dunes to gobble up the fertile land, white; Floods can be our lovely home. Relentless stuff we clear the river becomes cloudy. Dense forests become sparse clutter, the blue sky become dark, green mountains become bald. Mud-rock flow, dust storm, flood... These disasters are caused by a dirty environment. So we should protect the environment.

How to protect the environment? First of all, cant litter, saw rubbish pick up, is the environment become clean and beautiful. Second, do not arbitrarily trample flowers and plants trees. To plant trees, a variety of flowers and plants.

Electricity, bring us all kinds of convenience, especially gives us light, lit up the colorful world. But we want to save electricity, because electricity is mostly produced by burning coal. Save electricity is to save from coal, less waste, and only enough storage of coal mining in our country in one hundred years! We think, more than one hundred years later, our children and grandchildren to do? So we should save electricity, the usual lamp, use energy-saving light whenever possible.

Protect the environment, everyone duty. Lets start from me, start from now, start from the side of dribs and drabs.

我们住在美丽的地球上,可惜地球每天都饱受着被各种臭气、化学物品、毒汁、腐尸、汽车尾气、生活垃圾、工厂垃圾等等肮脏污染,使我们可爱的地球逐渐退化。所以保护环境是每个人义不容辞的责任。

花草树木是人类的天然氧气“制造厂”。但人们乱砍乱伐,使大自然的生态平衡遭到了破坏;沙丘吞噬了万顷良田;洪水冲毁可我们可爱的家园。无情的杂物把我们清澈的河水变得浑浊。茂密的森林变得稀疏杂乱,蔚蓝的天空变得灰暗,碧绿的青山变得光秃。泥石流、沙尘暴、水灾……这些灾害,都是由肮脏的环境造成的。所以我们更应该保护环境。

如何才能保护环境呢?首先,不能乱扔垃圾,看到垃圾就捡,是环境变得整洁优美。其次,不要任意践踏花草树木。要多植树,多种花草。

电,给我们带来各种便利,特别是给我们带来了光明,照亮了五彩缤纷的世界。但是我们要节约用电,因为电大多是烧煤产生的。节约用电就是节约用煤,少排废气,而在我国储藏的煤只够开采一百多年了!大家想想,一百多年以后,我们的子孙后代该怎么办?所以我们要节约用电,平时的照明灯,尽可能用节能灯。

保护环境,人人有责。让我们从我做起,从现在做起,从身边的点点滴滴做起。

Dear Tom,

How are you?

I would like to tell you something that took place in my school yesterday. In the afternoon the school held a growing-up ceremony for our coming 18-year-old birthday. At the beginning we made an oath that as grown-ups we should have a sense of responsibility for our society. Next we expressed our thands to our parents who brought us up and to our teachers for their education. Then our teachers gave us cards with good wishes. Finally, we had wonderful performances. I learned a lot from the activity. I am sure the ceremony is very important for us. From then on we will know our responsibilities as grown-ups.

Yours,

写作的时候少不了需要事例,欢迎阅读环境污染事例作文哦!

在一些国家,资本家或生产单位的经济人为了追求高额利润,任意向自然界排放各种有害物质,严重污染环境,特别是大气和水源的污染,造成社会公害,引起许多疾病,使广大人民的健康和生命受到严重威胁。

对水源的污染有多种,其中“水俣病”就是举世闻名的日本公害之一。

“水俣病”于1953年首先在日本九州熊本县水俣镇发生,当时由于病因不明,故称之为水俣病。

1950年在水俣湾附近渔村中,发现一些猫步态不稳,抽筋麻痹,最后跳入水中溺死,当地人谓之“自杀猫”。

1953年水俣镇发现一个生怪病的人,开始只是口齿不清,步态不稳,面部痴呆,近而耳聋眼瞎,全身麻木,最后神经失常,一会酣睡,一会兴奋异常,身体弯弓,高叫而死。

1956年在这个地区又发现五十多人患有同样症状的病。

经过对病的调查和研究,在1962年才确定水俣病的发生是由于汞的环境污染,特别是常期食用被污染的鱼和贝类引起的甲基汞慢性中毒。

这是从水俣镇的工厂排放的氯化甲基汞污染海域,使鱼和贝类中毒造成的。

继水俣镇之后1963年,日本新泻县又有大批自杀猫、自杀狗出现。

1973年在有明海南部沿岸的有明町等地又发生了水俣病。

据报导这三次发病人数共计900多人,实际上在日本受害人数远远超过这个数字,仅水俣镇受害居民已有一万人左右。

汞俗称水银,它广泛应用于许多工业部门。

汞及其化合物都是有害物质,尤其是汞的烷基化合物的毒性更大。

汞及其化合物可以通过呼吸或消化系统进入人体污染环境的事例作文。

无机汞进入人身体后,含汞浓度最高的是肾脏和肝脏。

有机汞在人脑中蓄积最为显著,其次是肝和肾

汞中毒后的临床症状即如“水俣病”症状。

造成水污染的工业公害除汞外,还有酚、氰类、铬、砷及某些重金属盐等物质。

这些物质从工厂及科研单位排放出来,造成了严重的水污染。

从而对人类造成的危害在国内外都时有发生。

因此在发展国民经济,加快四个现代化的进程中,一定要注意保护人类赖以生存的环境,防止污染,使人类在优美、舒适的环境中生存发展。
