关于核污染的作文篇1
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 won't 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.
关于核污染的作文篇2
保护环境是我们人人都要尽的责任。在我们居住的小区中，白墙上都会醒目的提示：保护家园环境，人人都有责任这句简单的时刻警示着我们。
有一次我去姥姥家小区的假山上玩，听到两个老奶奶坐在石椅上说：“听说这几个大土坑是要放大柱子的。”说着手边指向了那个装满垃圾的大土坑。我的目光也跟了过去，大吃一惊。只见那个大图坑简直是脏极了，有吃剩的雪糕、残留着辣油的塑料袋……看上去实在是太恶心了，简直可以起名字叫“臭垃圾坑”了，我赶紧离开那儿。
想想以前，假山上草丛郁郁葱葱，花香扑鼻而来。夏天我们在草丛里捉蛐蛐，听着那蟋蟀的歌声也是一种美好，而现在呢？估计连蛐蛐都都不愿意在这里安家了。假山上我们的欢笑也消失了。如果我是那个大土坑，人们把垃圾扔过来时，我多烦心呀！所以我们一定要爱护我们的家园环境。
我觉得保护环境就是看到一张纸把它捡起来，看到垃圾袋把它扔到垃圾箱内。其实还有很多我们力所能及的小事，让我们共同保护这美好、和谐的大家园吧！
关于核污染的作文篇3
所谓“大气污染”是指有害物质进入大气，对人类和生物造成危害的现象。如果对它不加以控制和防治，将严重的破坏生态系统和人类生存条件。
大气污染有的是由于森林火灾、火山爆发等自然因素造成的；有的`则是由汽车尾气、工业废气、烟尘、爆炸等人为因素造成的，其中人为因素对大气的污染是主要的，尤其是现代交通运输和工业生产对城市大气造成的污染更为严重。因此人们对大气污染问题越来越关切。
造成大气污染的物质有：一氧化炭co、二氧化硫so2、一氧化氮no、臭氧o3以及烟尘、盐粒、花粉、细菌、苞子等。
距地面几十米的近地面层大气，是人类和生物的生存空间。这一层空气质量的好坏直接影响着人类的生产和生活。近年来，由于交通运输业的发展，排放出的大量汽车尾气与空气中的一些物质成分发生化学反应，生成对人体十分有害的一氧化氮、臭氧、乙醛等新物质。
悬浮在大气中的各种气溶胶粒子，按其大小可分为降尘和飘尘。其中降尘的粒子较大，直径大于10微米，它的自然沉降率较快。它与人类支气管炎的死亡率和农业减产有很大关系；飘尘粒子较小，直径一般在0.1—1.0微米。其自然沉降率很小，故悬浮在大气中的生命史较长。随着粒子的减小有毒元素的浓度将增加。通常小于0.3微米的飘尘能直接吸入肺泡，如长期积累，会损害呼吸机能，引起哮喘、肺气肿、矽肺和肺癌等不治之症。由于飘尘的污染期长和毒性强，因此它的危害性大。当大气中气溶胶粒子增加到一定程度以后，就会出现烟雾弥漫，能见度降低，太阳辐射减弱等现象。
近地面层大气污染程度与气象条件密切相关，存在着明显的季节变化和日变化。一般冬季的早晨和傍晚在无风的天气条件下空气污染最为严重。夏季由于空气层结不稳定，污染物易向高空扩散，因此一般污染不会太严重。
关于核污染的作文篇4
今天，我看到了一张让我震撼不已的照片，一堵融化后的冰川竟酷似一张人脸，一张哭泣的人脸。看着这张照片，我在震惊的同时，更是百感交集：这张人脸难道不是在预示着什么吗？这难道不是呢？
垃圾污染
垃圾污染包括了工业废渣污染和生活垃圾污染两大类。它的危害很大，对水环境、大气环境、土地质量以及人体健康等都会造成严重的不良影响。垃圾，人们讨厌它，可是，垃圾的制造者是谁呢？造成垃圾污染的又是谁呢？让我们走进生活瞧一瞧吧——
路上走过一个青年人，他手中拿着一罐可乐和一包食品，吃完了，随手就将可乐罐和食品包装袋丢在了地上，完全无视不远处的垃圾箱。随后，又走过了许多人，但却没有一个人俯身将垃圾捡起来丢进垃圾箱。
这只是生活中一个很常见的例子。虽然垃圾的产生不可避免，并且因为人口的增长，垃圾的数量也与日俱增，但是为什么人们不能主动将垃圾扔进垃圾箱呢？又为什么看到垃圾不能将它捡起来呢？虽然你可以说，大家都在扔，我再怎么捡也只是杯水车薪，太微不足道了。但是，如果每个人都这么做，至少我们可以控制生活垃圾污染的扩大。
就让我们管住自己的手，让垃圾去它该去的地方吧！
树林减少
讲起树木，我就得说说我家门前了。那里原先是一片树林，树木郁郁葱葱，远远望去真是绿涛层叠，如诗如画。童年的我生活在这样美妙的环境之中，真是快乐无比。可是好景不长，有一天，来了一群人，把这里的树木全部砍掉了！如今我家门前如“荒山秃岭”，以往那种蜂飞蝶舞、百鸟争鸣的景象也荡然无存了；以往风一吹，树叶就会翩翩起舞，而如今却是飞沙走石，掀起的尘土让人眼睛都睁不开。我痛心疾首，却也无可奈何。
这仅仅是一处地方，那更多的地方呢？人们不知道保护树木资源，不加节制地开采树木资源，一张纸没有写完就丢掉、长时间使用木质一次性筷子等等因素都导致了树木数量急剧减少。日复一日，年复一年，地球上的绿色越来越少，连带着，鸟几这些动物朋友也失去了栖息之地。如今，人类的生活质量已经大大下降，空气变差，环境变差，身体变弱……让我们尽量少砍树、多种树吧！让地球再次成为人类的“天然氧吧”吧！
水资源受到破坏
水，是生命之源！我们的生活处处都离不开水。可如今，大量的工业污水、生活垃圾被排放到水中，导致原本清澈见底的湖水变成了又脏又臭的黑水；原本在湖水中自在游荡的小鱼，几近绝迹；更别说以前常见的在湖边洗菜洗衣的人了，谁还敢在这样的水中洗刷呢？更重要的是，人们生活中不可缺少的饮用水，也多了一股浓浓的消毒水味！想想以前那甘甜的水吧，水资源的污染，不仅影响环境，更直接威胁了人类的生存！
这一桩桩、一幕幕，是不是与这张“哭泣的人脸”存有因果关系呢？聪明的人们，智慧的人们，在积极改造地球、飞速发展科技的同时，同过身来，看看我们赖以生存的地球母亲吧！倾听倾听地球母亲的声音吧！地球母亲已经伤痕累累，不堪重负，她已经向她的孩子们发出了最后的警告！人类啊！醒醒吧！
关于核污染的作文篇5
air pollution comes from factories, power stations and cars. chemicals in the smoke from power stations cause a lot of damage. they can travel hundreds of miles in the wind before falling to the ground in the rain. but this "chemical rain" gradually destroys trees in the forests and kills fish in the lakes. in germany, over 50% of the country’s trees had been damaged by the year 1986.
time and time again there are serious accidents that pollute the air. in 1986 there was a bad accident at a nuclear power station in russia. a cloud of radiation crossed the whole of europe. it is said that 125,000 people died in russia as a result of illnesses caused by this accident.
in 1984 there was a serious accident at a factory in india and a cloud of dangerous gas covered the town of bhopal. over 2,500 people were killed that night, and hundreds of thousands of people were injured. many of the injured lost their sight.
关于核污染的作文篇6
周末，我在网上查找了有关广州污染情况的资料，知道了广州的污染主要有水污染和大气污染。
根据网上查找的资料了解到，造成污染的原因有：生活垃圾；大量农药等化学药品的使用；还有工业废物，包括污水、化学药品、废油等的排放等。
现在，很多工厂每天都会排放很多废气、污水，造成空气及周围环境受到污染；马路上越来越多的私家车和公共汽车每天排放大量废气，也让空气受到污染；生活小区内外都有人乱扔垃圾，搞得小区脏兮兮又臭哄哄的；还有很多人吸烟，每人每天都吸一些，整个城市也就多受到了污染。现在广州pm2.5、pm10、二氧化碳等指标上升得很厉害，说明空气污染比较严重。
为了保护我们生存的地球，我们应该从现在开始保护环境，少扔垃圾、多种树木，这样我们的地球母亲才更美丽！
关于核污染的作文篇7
health, surrounded by, smog, anything but, gases, impurities, absorb, poisonous, try hard, blacked out.
we all know that clean air is important to good health. wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air.
if there are impurities in the air, they may be absorbed by our bodies and make us ill.
we need clean air, but unfortunately, air pollution is globally present, especially in cities.
many large cities are anything but pollution-free. our cities have many factories, which we need to make food, clothing and other things.
every year these factories pour millions upon millions of tons of smog into air.
power plants and houses that burn coal add greatly to air pollution. besides, there are more cars in cities now.
once out on the streets, they will take in fresh air and replace it with poisonous gases.
our country is trying hard to prevent and control air pollution. as long as every citizen also realizes its importance and makes join efforts, the day will come soon when people will take in only clean air.
then, the sunlight will no longer be blackened out by smoke and soot.
