Cars and Air Pollution

Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly.

On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

Protection of the Environment Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive. We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products arestill put into rivers. We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycie them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly.

Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people.

When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health.

The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air.

Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases.

在21世纪的今天,人类的科学经济发展已经达到了很高的水平。然而我想问:你们有没有意识到人类的活动对环境会造成怎样的影响呢?

环境的污染270字作文1

我们的环境污染我们的环境污染我们现在的生活比以前好得多,但环境跟以前简直就不能比。以前的空气清香并掺和着花草的芳香,河水清澈见底.........而现在呢?汽车排出的废气和工业废气相当多,河水臭气直出.........我们大家为了过上好生活,都买汽车,但车主们有没有想过这样的量使用汽车的后果。有些地方之间的距离非常近,但车主们不想跑,就直接开汽车。假如一辆汽车一天排放一千克废气,那么中国每天大约有几千万辆汽车在行驶,那么一天就要排放几千万千克的废气。

这个数目仅显示一天一千克的废气排放量和仅计算中国的废气排放情况。工厂的污染更严重,水和空气都要被污染。大量的废水排入大海和河流之中,以致大量的鱼虾、水中植物死亡和大量的水资源被污染.........我们地球上的资源也在一天一天的减少。大量可回收的品中只有3﹪是被回收并再生的。许多白色垃圾造成了白色污染。我心中的家园是和以前差不多的,可是这是很难挽回的。为了我么大家共同生活了几千万年的蓝色星球?——地球的美好未来而努力吧!

环境的污染270字作文2

随着科技的不断发展,汽车的不断增多,排放的废气已经造成了严重的污染,或许,几年后的子孙后代、几百年后的大家,或许会因为大气污染而死亡。现在,地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡,如果这样延续下去,地球在几万年后岂不是变得光秃秃、像月球一样了?

据科学家的统计,每一年,每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡,大家或许会觉得很夸张,但这是事实。其次还有受到污染的废水、废气等。人类有错吗?

我多么希望大家能珍惜我们身边的每一个事物,每一只动物,每一只有益的细菌,因为,很有可能,在几万年后的今天,他们都没有了。

动物对人类发起了警告;

细菌对人类发起了警告;

每一条无辜的生命对我们发起了警告。

“人类,不要再害你自己,不要再害死我们了吧!”

环境的污染270字作文3

这里有几片茂密的森林,森林之间有一条清澈的小河,就就像一条蓝色的绸带。

可是 ,渐渐地周围的森林被砍伐的所剩无几了,小河中原来清澈的河水也不见了踪影,却变成了臭气熏天的臭水沟。这都因为人类无情的破坏!小燕子对小鱼说:“人类 太可恶了,不仅把地球母亲弄得千疮百孔,还把我们赖以生存的家园给破坏了!“小鱼说道:是呀,因为人类 ,现在的水质变得越来越差了,我简直活不下去了。还因为人类工厂的废气排放,让我再也看不到湛蓝的天空了!”

当我看到了这个情景,我攥紧拳头,心里又伤心又愤怒,我想:那些人们有良心吗?请你们珍惜地球吧!

环境的污染270字作文4

在21世纪的今天,人类的科学经济发展已经达到了很高的水平。然而我想问:你们有没有意识到人类的活动对环境会造成怎样的影响呢?

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失,使许多地区成为沙漠。人类的活动范围在不断减少,这不可怕吗?

人类除了破坏森林之外,难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性,目前世界上60%的地区面临供水不足,已有20%的人口难以得到清洁水,51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的,现在的工厂及我们生活中的污水,没有通过处理就排出去。这不是最好的吗?据研究,每排放1立方米污水,就污染14立方米天然水。想一想,这是多么可怕的数字?

在工厂排出的浓烟里,我们不知道浓烟是污染大气的吗?科学家发现,至少有100种大气污染物对环境产生极大危害,直接影响人们的健康。

难道我们想在这种环境中生活吗?当然不想;那让我们用行动来证明吧!我们可以从我做起,从现在做起,从身边做起。树立爱自然、爱护环境的意识吧!来做宣传环保的使者!让我们一起为保护环境行动起来吧

人类一直以为地球上的水和空气是无穷无尽的,所以不担心把千万吨废气送到天空去,又把数以亿吨计的垃圾倒进江河湖海,最终人类生活的地方范围将会慢慢缩小,直至消失。

人类没有注重对青山、绿水、蓝天、大海的保护,私采矿,滥伐树、乱排污水乱放污气、过度放牧、过度开荒、过度开发自然资源、破坏自然界的生态平衡等等。

正所谓:你中有我、我中有你。

近年来,由于人口急剧增长,工业迅猛发展,土壤表面堆放和倾倒,有害废水不断向土壤中渗透,大气中的有害气体及飘尘也不断随雨水降落在土壤中,导致了土壤污染。人类食用后,会影响健康。

多数大城市里的空气含有许多取暖、运输和工厂生产带来的污染物。这些污染物威胁着数千万市民的健康,导致许多人失去了生命,这叫做空气污染。

现在城市巨大,这些大城市的无序扩大也损害到了自然区。因此,无限制的城市化应当被看作是文明的新弊端。

最近几十年,在1980-1990年,世界上有1。5亿公顷森林消失了。按照目前这种森林面积减少的速度,40年以后,就再也见不到一棵树了。

水是不能制造的,一定要珍惜水资源。水饥、水荒、水枯、水污的缠扰,作为“水”的关键点。

臭氧层臭氧层被破坏后,其吸收紫外线的能力大大降低,使得人类接受过量紫外线辐射的机会大大增加了。在北极地区,因为太阳的辐射,冰块全部破损,北极熊无家可归。

所以自然保护很重要。

Everybody is responsible for environmental protection,. I accidentally caught a cold, do not know why, so he went to see the doctor, my mother asked the "flu?" Asked his mother.

The doctor shook his head, said: "because there are too many viruses in the air, is full of garbage, house dust, industrial emissions, and so on, these are the cause of poor air quality, virus." I seemed to understand a lot.

With the development of the society, living standards continue to improve, we drink the tap water, use the TV set, refrigerator, heater, elevators, etc. But in life, we constantly in the waste of resources, clean water, watering the flowers in the water, washing water, waste every day. Water for us to be of much use, irrigate farmland water, building water, plants and trees need water, and peoples life water for industrial water, we cant live without water. However, as we waste water was contaminated. If we use wash bowl of water to water the flowers and clean the water to wash clothes, wash your hands when the water is boiling down a little, that how much we want to save water. Electricity, as usual, we open a lamp less per person a day, watch less TV for an hour, less a elevator, how much we want to save electricity. When we are standing on the street, smell the stench, walking in the street is full of garbage, look up at the sky gray, one after another car emissions both in the exhaust, and people in disorderly cut down trees? Observe, to think of it, our environmental protection consciousness is so bad.

Nature cannot be improved, the life can choose to choose green, environmental protection, everybody is responsible for.

环境保护,人人有责。 我不小心感冒了,不知道是为什么,于是就去看了医生,妈妈问这“是流感吗?”妈妈问。

医生摇了摇头说:“因为空气中有太多的病毒,到处是垃圾,修房子的灰尘,工业排放的废气等,这些都导致空气质量差、病毒多的原因。”我似乎明白了很多。

随着社会的发展,生活水平不断提高,我们喝上了自来水,用上了电视机,冰箱,取暖器,电梯等。但生活中我们不断地在浪费资源:打扫卫生的水,浇花的水,洗衣服的水,每天都在浪费。水对于我们有多大的用处,浇灌农田要用水,修建房屋要用水,花草树木需要水,还有人们的生活用水工业用水等,没有水我们就无法生存。然而水在被我们浪费,被污染。如果我们用洗碗的水来浇花,洗衣服的水来打扫卫生,洗手时水开小一点,那我们要节约多少水。电也一样,我们每天每人少开一盏灯、少看一小时的电视,少座一次电梯,我们要节约多少电。当我们站在街上,闻到的是臭气,走在大街上到处是垃圾,抬头看天空灰蒙蒙一片,一辆接一辆的汽车都在排放着尾气,还有人在乱砍伐树木?注意观察,仔细想想,我们的环保意识实在太差了。

自然不可改良、生活可以选择 选择绿色生活、环境保护,人人有责。

with the development of economy, more and more high buildings are being built in large and medium-sized cities across the country. in urbanization, however, one thing should not be neglected---environmental protection. it is unscientific to judge a city’s modernization level by the number of high buildings. recently, a new concept “environmental image” has come into being and become an important criterion with which to evaluate a city.

the concept stresses that a modern city must have efficient environmental promotion. it must have a proper proportion of green land, clean water and fresh air. to add more greenery to a city, i would like to make the following proposals:

1. we should popularize “vertical greenery” technique, that is, to plant more green-leaved plants like boston ivy in densely-located buildings. the roof space of buildings should be used fully to plant flowers, fruits and grasses.

2. certain room should be reserved for green belts, green patches in the building of new residential districts and the reconstruction of urban areas.

3. measures should be taken to strengthen people’s awareness of greenery. people should, for example, be encouraged to plant “wedding trees” and “birthday trees”.

中国是一个人口大国。为了解决人口问题,我国政府决定实施独生子女政策。执行一段时间后,许多人不仅看到了这个政策的优点还有缺点。因此,人们开始推崇二胎政策。在我看来,二胎政策是应该实施的。作文

First of all, two-child policy is the gift for some only child. For some families, maybe the parents are only child and they also can have only child. Put aside the loneliness of their child, when their child grows up and they grow older, their child marry with an only child girl accidentally, the burden on their child and his wife is unimaginable heavy. Their child and his wife have to take care of two old couples. Usually, a young couple looking after an old couple is a little difficult; if the pressure increasing twice, how can they stand it. But if their parents have two children, they can share the burden of taking care of their parents. It would be much better.

首先,二胎政策对于一些独生子女来说是天赐的礼物。对于一些家庭来说,也许父母都是独生子女,而他们也只生一个孩子。抛开孩子的孤独不说,当他们的孩子长大了,而他们也变老了,他们的孩子又和一个独生子女结婚,这样的话,压在他们孩子和孩子妻子肩上的压力是不可想象的。他们的孩子和他的妻子不得不照顾两对老人。通常,一对年轻的夫妇照顾一对老人就有点难了;如果压力增加了一倍,他们怎么能忍受呢。但是如果他们的父母有两个孩子,他们就能分享照顾父母的压力。这样会比较好。

Secondly, two-child policy can guarantee the number of Chinese population. As the widely spread of one-child policy, some people have changed their conception about giving birth. If they firmly believe one-child policy, there will be more and more the dink. After several decades, our country will famous for lack of population.

其次,二胎政策可以确保中国的人口数量。由于广泛宣传独生子女政策,有些人已经改变了他们的生育观念。如果他们认同独生子女政策,就会有越老越多的丁克族。几十年后,我国就会以人口短缺而著名了。

In conclusion, one-child policy has out of date. And tow-child policy is needed and necessary. It can solve the problem of nowadays and the future.

总之,独生子女政策已经过时了。二胎政策是必要和必须的。这可以解决当前和未来的问题。

篇16:汽车污染环境的作文

全文共 1145 字

在我们的家乡,由于经济较为发达,几乎每家每户都拥有车子。汽车已经成为人们不可缺少的交通运输工具。它给我们们的生活和工作带来了极大的便利。但是,由于汽车数量的不断增多,汽车排放出来的尾气,也给地球妈妈带来了极大的危害。趁着周末,我们决定对“汽车尾气的危害”做一个调查。

通过上网查找资料,我们了解到汽车排出的废气中含有1000多种气体成分,其中对人体健康和环境危害最大的有一氧化碳、碳氢化合物、氮氧化物、二氧化碳等。一氧化碳是汽车排放废气中浓度最大的污染物,是无色、无味、无臭的窒息性气体。吸入过多一氧化碳会使人体缺氧,使中枢受损,引起功能性障碍,直至死亡。氮氧化物是各种含氮化合物的总称,汽车尾气中以一氧化氮居多,并有少量二氧化氮。氮氧化物的毒性很高,有强烈的刺激作用,会导致胸闷、咳嗽、气喘、肺炎乃至肺水肿。二氧化碳是大气主要的温室气体之一。排放过多,会使全球的气温升高,引起气候的不断恶化。

为了证实这一危害,我们把要做实验的意图跟家长说了,并征得了他们的支持。我们叫周旻晖爸爸发起车子,不要前进,原地不动。又拿出一盆开得正旺的菊花放在小板凳上,将小板凳拿到了汽车排气管后。一股股臭熏熏的黑烟从花瓣间飘过,一两分钟过去了,花儿还和原先的差不多;五分钟过去了,有几片花瓣已经凋谢了,十分钟后,那原先湿润的土壤都变得非常干燥,没有水分了。二十分钟后,那原先饱满、充满活力的茎都变得紧绷绷的,好像一根电线。通过这个试验我们明白了汽车尾气对植物的危害确实是很大的。

但是,为了进一步证明汽车尾气对动物有没有危害,我们又做了个实验。我们去王哲奶奶家的鸡窝里抓来了一只小鸡。那只小鸡一直望着我们,我们心想:为了证明汽车尾气排放对人类有哪些危害,已经牺牲了一盆花了。现在要拿这只可怜的小鸡做实验,真是有点于心不忍呢。但是为了寻找问题的答案,我们咬咬牙,还是决定坚持做下去。和上次差不多,我们先把小鸡用一个笼子关着,摆放在排气管后面,然后又叫叔叔将汽车发动。一股股黑烟又从排气管里冒出来了,一会儿功夫,小鸡的绒毛就被熏成灰色了。10分钟后,我们看到小鸡被熏得奄奄一息了。为了保住小鸡的性命,我们赶紧将它拿开,放在地上。看到小鸡跌跌撞撞的,我们心里一阵阵酸痛。我们对叔叔说,原来汽车的尾气对植物和动物的危害真的是这么大的呀。周旻晖爸爸语重心长的说:“任何事物都有两面性的。汽车作为人类进步的产物,它给人们带来了许多的便利,但同时也给人们带来了很多的危害啊。现在我们们国家也是很注重环境保护的,有很多城市都已经在开展‘无车日’活动了。”

是呀,为了我们这个赖以生存的地球,我们要争做环保小卫士,积极宣传汽车尾气对人类的危害,请爸爸妈妈们少开车,能步行的尽量步行,不仅环保,而且还可以锻炼身体,这样是不是一举两得呢?

篇17:环境污染的原因

全文共 4991 字

一:环境污染的根源

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。

二:环境污染

就最近这几年来看,随着各地区的经济迅猛发展,环境污染问题也越来越严重,保护环境,维持生态平衡也成为了我们每个公民应尽的责任和义务,也是为了社会更好发展的一项重要举措!

何为环境?从哲学的角度来看,所谓环境,主要指我们所研究的主体周围的一切情况和条件。对于人来说,环境是指人生活于其中,并能影响人的一切外部条件的综合。人的生活离不开好的环境,在人类几百万年的历史进程中,环境对开创人类文明和进步发挥着巨大作用。

大气资源、水资源、土地资源等等,都是让人类得以生存的物质基础;而森林资源、矿藏资源等资源又为人类的不断发展提供物质,创造出地球上高度的人类文明。但是,人类在开发利用环境资源的同时,也对自己的生存环境产生了一系列环境问题。

在我们身边就有很多污染环境的污染物,例如说:大量的生活废弃品,塑料袋(也称白色垃圾),一次性木筷,一次性饭盒,果皮纸屑。污染物对环境来说,毫无疑问,肯定有很大的危害,例如动物的腐烂的尸体会影响环境卫生,而且还会滋生细菌。饭店、餐馆认为很卫生的一次性木筷,使用后随便一扔,影响了市容,破坏了环境。。

现在像我们柳疃镇、青乡乡,最近电网部门纷纷撤除喷水机器的使用。喷水机的使用对环境的污染更加恶化、污染了水资源对人们的身体健康危害甚大。人类的活动会使大量的工业、农业和生活废弃物排入水中,使水受到污染。又例如说,我们北部渤海湾受到工业、印染厂的废弃物排放大量鱼虾死亡,地区农民上海捕鱼,鱼的体内含有大量化学物质对人们的身体健康造成了危害。据资料统计,目前,全世界每年约有4200多亿立方米的污水排入江河湖海,污染了5.5万亿立方米的淡水,这相当于全球径流总量的14%以上。1984年颁布的中华人民共和国水污染防治法中为“水污染”下了明确的定义,即水体因某种物质的介入,而导致其化学、物理、生物或者放射性等方面特征的改变,从而影响水的有效利用,危害人体健康或者破坏生态环境,造成水质恶化的现象称为水污染。水的污染有两类:一类是自然污染;另一类是人为污染。当前对水体危害较大的是人为污染。水污染可根据污染杂质的不同而主要分为化学性污染、物理性污染和生物性污染三大类。

最近,我发现政府部门、昌邑环卫局开始大力整治环境,沿街排查污染源,青乡街也定点安置了便民垃圾桶,替代了原来垃圾围绕街道,臭气熏天的状况。各个村庄开始整治村内环境的污染源,使街道、村庄焕然一新!而这不是主要的,更重要的是我们每个人自觉保护环境,保护我们赖以生存的家园,为了我们更为了我们的后代,树立好榜样,奠基好基础,让我们的家园更加美丽、更加丰富多彩!

所以呢!环境与我们的生活密切相关,保护环境卫生从我做起,从现在做起:不随地吐痰;不乱扔垃圾;废弃电池和塑料袋要处理好;多植树造林,不践踏草坪;不污染水源。保护环境,我们有责!看你的行动喽!

小建议:家庭生活中的塑料瓶可以做成装饰品,可回收物品可以卖出,换来金钱买实用的东西岂不很好?一次性木筷消毒清洗一下可以做成装饰品,你也能开小店赚大钱了!化废物为贵宝,让自己的心情更舒畅,让自己的心灵更纯洁,让自己的家庭更温馨!

三:环境污染

在二十一世纪的今天,人类赖以生存的地球环境越来越恶劣,灾难频发,旱灾、洪涝灾害、土地沙漠化、地震、全球气温上升、海啸等等过去,以我所受到的信息宣传,简单以为环境污染只是浓烟滚滚,或者水面上漂浮着垃圾、发出恶臭,蚊虫成堆、尘土飞扬等等。但是,今年从网络、报纸、广播、电视、人们的关注里,我似乎明白;现实的情况要糟得多。西南五省大旱,就是我们自己想都没有想到的原因,专家分析:因为在过去10几年中,西南从新西兰大量引进桉树速生林,为了求短期的经济利益,毫无限制的大面积种植,以用来工业造纸,从而导致物种生态环境失衡,形成地下水严重缺失。俗话说,十年树木,百年树人,可这种桉树两三年就成材,是一种巨大的抽水机和抽肥机,不断侵蚀着其他植物物种的生存空间,而当地人却沉浸在多种树就可以保护环境的僵化错误的指导思想中,不断的在往恶性循环上发展,正是这个想到想不到的原因最终导致西南几百年的大旱灾。在报纸上,我看到温总理在一片干涸开裂的耕地上,捧着一颗枯死的禾苗,只说了一句话:“痛定思痛!”云南拥有大片的原始森林,风景名胜众多,地理环境独特,自古以来就是一个山清水秀,气候宜人的好地方,可是为了种植这种桉树,大量砍伐原始森林,想象这些经过几十年甚至数百年才形成的树木,仅仅是为了去满足最快速度的造纸而被破坏,真是让人可惜,并且痛心。据说旱灾的另一个原因,就是所有的大江小河都修起了水电站。对这一点我有自己的感受,早两年湘江的水面多么宽广,可是上游修了一个水电站后,下游的水明显减少,甚至连河床都经常露出来,同时影响到了城市自来水的引水工程,我都有这些感受,那些江河里小鱼虾们感受就应该更深了。前些天报纸上又爆出地沟油事件,报纸上说地沟油是别人吃完的饭菜倒进垃圾桶后,一些黑心商人把这些进行简单的提炼加工后,不但闻不出异味,加入香精后吃起来还挺香,但是对人体危害很大,我现在都不敢随便在外面吃东西了。环境污染的问题日益严重,影响到了我们生活的方方面面,对此我感到非常的忧虑。

四:河道为什么会污染

在我们学校旁边,有一条小河,听长辈们说,原来这里的河水清澈见底,河里鱼虾成群,夏天人们喜欢在水里游泳,还直接取水饮用呢!可如今,河水不但变得混浊,有时还有臭味呢!

为什么河水会发生翻天覆地的变化呢?经过我们全班同学的观察分析,河水污染有许多原因 。首先,人们不重视环保,乱倒垃圾。如有一次,我去张微家去玩,吃了一根香蕉,问她的妈妈:“阿姨,香蕉皮扔哪里?”只见她从我手中拿过香蕉皮,又随手用力一扔,扔进了小河,说:“这就是我们家的垃圾桶。”甚至有人把死猫死狗也扔进去了,这时,如果你从旁边经过,一阵阵臭味就会扑鼻而来。我真是不明白,人们为什么不多走几步把垃圾扔到垃圾箱里让垃圾车运走呢?。其次,人们家里的化粪池的排污口就直接通向小河。特别是我们学校,大小便没有经过处理就流进了小河,让人看了真是恶心。河水不变臭才怪呢!还有人们给庄稼喷了农药后,就在河里洗药筒等等。由于各种原因使河水变得越来越脏,甚至发臭,更不用说饮用,就连小鱼也快要无家可归了。

我想向人们呼吁:“水是生命的源泉,没有水就没有生命,就没有我们这个美丽可爱的家园,所以请你们不要再伤害小河了,难道你们就没有看见小河在哭泣吗?”

阳光透过树叶的间隙洒落在我的窗前,我终于睁开那迷蒙的双眼,准备迎接新一天精彩到来。微风将白云从吹散了,我些许的倦意似乎也被吹散了,无意间望见生长在烂泥之中的橘子树,可我并不担心,因为它依然那么翠绿挺拔。

在归去的途中,我又似有意无意地朝那望了又望,终于我从烂泥之中拔起了它,以尽可能快的速度回到家中,将它栽在院落中,与其它种植作物生活在一起。院落很大,阳光充足,何况我还会悉心照料,我想,它一定会生长得很好。心中一直这样想,感觉心中有个可爱的小生命在向我朝手,许多植物都似

乎披上了一件金衣,向我展示它们的魅力。我打开笔记本,记了下这个难忘的时刻。

暴风雨来了,我急忙奔向院落,却瞥见橘子树叶子掉落了,虽然依然翠绿,

但躺在地上零零落落,如同一只奉上祭坛的大鸟掉落的羽毛,低吟着壮烈的悲歌离去。我不禁望向乌云连绵的天空,仿佛是它为我改变植物的命运而感到不公,雨夹杂着微风从空中飘落,时间仿佛在那一刻停止。我抱怨着时间的冷漠,在我尽情采取幻梦花朵时,依然分秒不差地滴答着,却在失落时让我沉默。

为什么橘子树在舒适的院落里会掉叶,而在烂泥中却能茁壮成长?我在拔起它的那一刻并未思考过这个问题。对啊,这大千世界,万象纷呈!行走其间,总有令人沉醉之处,也一定会有令人伤心之时。而今我的忏悔是否能填补它心中的失落?

当阳光再次照进我的院落之时,我则已将橘子树移回烂泥之中。只希望还它一个自己喜欢的生长环境。过了一段时间,当我再一次到烂泥中探寻时,我惊喜地瞪大双眼,橘子树枝头又重新泛出了绿意。我感叹道:原来这是你的选择!

徘徊在心头多时的问题成功得到了解决,那就是万事万物都有它自身的生长规律,怎样选择,那是它的不二法则。
