环境污染类作文通用7篇

环境污染类作文篇1

我的家乡在荆州。平时,我对家乡的环境也不大了解 。这几天,我们班组织同学们进行了一次综合实践活动,对家乡的环境进行了一次调查,调查的主要对象就是荆州的护城河。这次调查让我受益匪浅。

通过实地调查和上网查资料,我了解到以前的荆州护城河污染十分严重。护城河两侧共有二十多个排污口,每天城区的生活及工业污水排入护城河,直接排入的总污水量约5万立方米。因此,河水变成了浑浊的墨绿色。居住在附近的居民和过往的行人也很不爱护环境,把垃圾随随便便仍进河里,使河水的污染进一步加重。由于护城河就是死水,无法流动,河底淤泥非常多,水面上漂浮着大量的蓝藻,河底的沉积物散发着臭味。人们从这里经过,都要捂着鼻子,加快脚步。

护城河的污染成为了荆州人的心中之痛。在广大市民的期盼下,市政府对护城河进行了彻底的治理。经过清淤、补水、截污、绿化……护城河面貌焕然一新。

如今的护城河碧波荡漾,波光粼粼。护城河宛如一面绿色的大镜子,映出了蓝天白云和古老城墙的美丽倒影。几只鸭子在水面上嬉戏,几条小船在小河上悠闲地驶来驶去,真可谓“舟行碧波上,人在画中游”。河岸上杨枊依依,与古老的城墙交相辉映,美不胜收。

通过这次的环境调查,我增强了环保意识。我们一定要好好保护环境,让我们共同的家园天更蓝、水更清、景色更美!

环境污染类作文篇2

这是最大的快乐的道理。而我们为了钱可以牺牲一切。由于环境污染,工作过度,饮食不当等等,带走了数以千万计的中国人的健康,带走了他们的快乐。

我国目前污染是世界上最严重的。主要污染物排放总量高,近年全国每年排放二氧化硫约2000万吨,废水约400亿吨,全国城市垃圾年清运量1.49亿吨,进行无害化处理的仅有一半;工业危险废物每年产生1100多万吨,处置率仅为32%;二氧化硫排放居全世界第一,二氧化碳排放居全球第二;城市河段80%以上受到了严重污染;80%以上的城市空气污染严重,全球十大污染城市我国占8个;2/3的城市居民生活在超标的噪音环境中;农村面源污染日渐突出;酸雨面积接近国土的1/3,国土荒漠化以每年2600多平方公里的速度扩展;海洋污染严重,赤潮频频发生。

卫生部承认,目前中国有毒有害企业超过1600万家,导致2亿多人受到职业危害。以矿工中常见的'尘肺病为例,据不完全统计,中国累计发生尘肺病人数已相当于世界其他国家尘肺病人的总和。国外专家估计,目前中国有500万多名尘肺病患者。中国国家环保总局副局长潘岳不久前表示,根据2003年的统计数据,流经城市的河段90%受到严重污染;有近3亿农村人口饮用不合格的水;全国近2/3的城市人口生活在严重污染的空气环境中,每年仅肺癌患者新增就有100万人!

污染不仅严重损害人们的健康和扼杀生命,还造成巨大的经济损失。保守估计,近年仅污染造成的损失就占gdp的7%到10%。这说明我国一段时间以来的经济增长,是以牺牲环境换来的。如果在gdp中扣除污染损失,不少年份是负增长。生活在这样的环境中,人生能快乐吗?

环境污染类作文篇3

今天的生物课,我们学习了环境污染,对生物的影响,这节课我知道一些环境污染的形成,环境污染的后果和拟定保护生态环境的计划。上完课后,我感觉人类在为自己挖“坑”。

比如在南方常见的酸雨,酸雨是指燃烧煤、石油等化学燃料燃烧时产生的二氧化硫和氮氧化合物,在空气中的与水分结合,从而形成的ph小于五点六的雨水,所有中所含的酸性物质是硫酸与硝酸。酸雨的形成就是与化工厂的排放的废气有关,酸雨可以让水土的营养不被植物吸收,酸雨可以让水酸化,从而让水中生活的动物死亡,酸雨可以腐蚀建筑建筑……有的一些工厂为了图一时的方便,排放了大量有害气体,日积月累,渐渐形成了酸雨,一场酸雨都会给生态系统带来巨大破坏。

人们使用冰箱与空调是件正常的事,但这样也会把臭氧层破坏。冰箱与空调中含有氟利昂,臭氧层就是被这种化学物质破坏,臭氧层能有效的过滤太阳辐射中对生物有强烈破坏作用的紫外线。现在的臭氧层被破坏,就无法滤去紫外线,导致大量阻碍线辐射到地面,从而危害生物的健康,例如人皮肤癌和白内障等疾病因此而明显增多。控制对氟利昂的使用,是保护大气层的关键。

人类图一时的便利,而给自己挖“坑”,这个坑可能会越来越大,直到人们摔进去了,人们才醒悟,现在我们已经知道有这个坑了,为什么不预防呢?

环境污染类作文篇5

many people are active in fighting against unfair treatment to colored people, women , animals and so on. right now i am talking about fighting for respect to our environment. though the environment doesn’t have a mouth to deprecate what humans have done to her, she retaliates through action. in the early years the chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods.

as a result,the huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. another example was in several developed countries. because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. what horrible scene! what we are suffering is only a small part of what the nature once suffered. if we don’t take action to show respect to the environment, we will have to face an increasingly awful situation. measures should be taken to protect the environment on which we are relying.

first governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. second voices should be made to announce the public of the importance of protecting the environment. third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems. only by changing the way we treat the environment can we get along well with it. only by saving the environment can we save ourselves.

环境污染类作文篇7

环保的重要性是世人皆知的。环保是我们每个人义不容辞的责任和义务。如果大家不环保,那么我们这个世界即将被推到生死边缘。

我常常想:环保是什么?绿色又是什么?

当我们看见鸟儿在天空中遨游,您一定认为世界上的动物多得数不胜数吧!噢,不得不告诉您您完全想错了,如今,由于人们的大量捕杀和环境的日益污染,动物的家园已成了一片灰色,它们的生存已经受到了影响,正面临着危机,频临着灭绝。动物的生命与人类的生活息息相关。人们伤害动物就等于伤害自己。

水是生命的源泉,一切生物都离不开它。现在,工厂越来越多,大多数河流都因为它们排放的污水而受到了污染,许多的小溪成了黑色的。动物们遭遇悲惨的命运。想象一下,如果您只能用生活中被污染的水,洗脸、洗手、洗头发了,人生中如此苦恼的事,你该怎么办?如果您家中停水一天该怎么办?一个月?一年?如果您走在沙漠里,炽热的太阳烤晒着大地,此时您已渴得嘴存干裂了,却没有一滴水,或许我们只有在这样的情况下,才会感到水的可贵,才能懂得珍惜水。

树木,绿色的象征,它不但能净化空气,还能起到光合作用。每天都能听见嗡嗡的电锯声和一棵棵大树的呻吟声或倒下时发出的怒吼。原本郁郁葱葱的树木,而如今却只剩下了棕色的树干。树木在频频减少,昔日茂密的树林已剩寥寥无几了,这也使得沙漠面积在不断扩大,使得动物少了栖息的地方,使得大自然缺少了生气,最严重的则是山洪来临时,人们在也不能依靠树来抵挡了,会使得自然灾害更加猖狂,无情地来伤害人们。这难到不是我们自己在毁坏自己的生存环境吗?

亲爱的朋友们,我们生活中的绿色已逐渐被黑、灰、棕、土黄所替代,我们是明天社会的主人,地球的命运掌握在我们手中,在此我号召大家:

让我们用双手,多种一棵树;

让我们站出来,保护野生动物;

让我们行动起来,保护自己的家园;

让地球上的树更绿,天更蓝,水更清;

让我们的家园处处开满绿色的环保之花。
