地球晚们人类赖以生存的家园,它就像母亲一样,为我们提供生存资源和条件,谁不想让自己的家园变得更美,然而现实情况是我们地球已经伤痕累累了。保护环境已刻不容缓了。
人们经常把保护环境挂在嘴边,可真正做起来却不往往有些困难。就拿塑料袋来说,人们都知道使用塑料袋会造成白色污染,也知道国家的限塑令的要求,可是人们还是在用,我们身边环境污染的例子还有很多。例如人们大都知道废旧电池回收不当会污染环境,但许多的时候我们却把它们随手一扔。另外,我们周围浪费资源的例子还有很多很多,使用一次性筷子,常常忘了关水龙头等,为此根据实际情况我提出以下建议。
一、加强环境保护知识的宣传,教育市民收听、收看关于保护环境的节目,阅读环保知识读物,讨论环境保护问题,与破坏环境的现象作斗争。
二、倡导市民节约纸张,节约粮食,节约有水,节约用电,节约燃料,共同节约我们有限资源。
三、把损坏的物品修理好再用,延长使用期,多使用循环用的物品,不用或少用一次性纸制品。
四、设置专门回收部让垃圾及时回收并合理利用。
五、引导市民购买有环境标志和绿色标志的物品,不吸烟,不随地吐痰,不使用会破坏臭氧层的物品。
六、保护野生动物,不采摘花朵,不砍伐树木。
我们共同,一定会创造一个美好家园!

我常常在电视上看到,许许多多的公益广告都在说:只要我们每个人都打开一扇窗,世界将会变得更加明亮。

+ 加入清单今天我和妈妈在八街坊看到一条小河,小河特别脏,河水像倒了许多浓墨似的,很黑很黑。河面上漂浮着一层油,河面上还躺着许多塑料袋、杯子等。河水很臭,阵阵臭味直往我鼻孔里钻,小河无声地流淌着,像在偷偷哭泣。我问妈妈,河水为什么这么脏?
妈妈告诉我,以前这条小河很干净,很美丽。河水很清很清,里面有许多小鱼在水里自由自在地游来游去。河水很甜很甜,吸引了许多小鸟来喝水。水里还有许多水生植物,充满了生机。后来,这条小河被人们弄脏了,人们把大量的生活垃圾都倒在了河里,工厂把大量的废水都排进了河里,水里的小鱼都被毒死了,小鸟再也不敢来喝水了。从此,小河再也没有生机了。
听了妈妈的这些话,我感到非常可惜。我想:以后人们再也不能把生活垃圾倒进水里了,工厂再也不能把废水排进河里了。我们每个人都要爱护身边的环境,使我们身边的环境更加美丽。

过去,人们不必担心保护环境的问题。因为那时地球上人口稀少,自然资源似乎取之不尽。如今,一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源,有毒化学制品的使用也正污染着环境。如果我们继续这样下去,地球上的生命将不复存在。我们都明白如果从海里捕捉太多的鱼,海里就不会再有鱼了。可是,现代化的捕鱼技术使得捕鱼量越来越大。我们都明白如果砍伐太多的树木,森林就会消失。可是,我们仍旧使用强大的机械砍伐越来越多的树木。我们都明白如果河水被废弃物污染的话,我们仅有死路一条。可是废弃物仍然源源不断地进入河里。
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。
我们明白,人口继续照此刻这个速度增长的话,不出几年,就会发生食物短缺。我们该如何解决这些问题呢?如果我们多吃蔬菜,少吃肉类的话,我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。如果我们学会再利用的话,自然资源就能持续更久。如果人们使用现代化的生育控制方法,世界人口就不会增长如此迅猛。
Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future。
最终,如果我们能够教育人们都意识到这些问题的话,未来我们就会有一个更好、更洁净的星球。

+ 加入清单星期天,我去姥姥的老家玩。走在路上,一望无边的田里,农民正忙碌着收割庄稼。突然,一阵阵黑烟飘来,呛的我直咳嗽。我一边跑一边问:“这是哪儿来的烟?呛的我快受不了啦!”旁边的人也直抱怨:“是呀,这几天焚烧麦杆,我们坐在附近的也倒霉了!”另外一个人也连忙接话:“是呀,这样下去世界会变成啥样子呀!”看着滚滚浓烟,我仿佛看到了许多年以后的情景:
早晨刚开门,一阵黑烟直扑进来,人们不得不戴上厚厚的口罩。回家一进门就要赶紧把门窗关紧,否则全家人就得不停在咳嗽。尽管室内空气混沌,人们却不能打开窗户透透气,也不敢出门游玩。从窗户望出去,浓烟滚滚,空气再也不清新了。花草树木有的熏死了,活着的也一个个耷拉着脑袋。公园里最漂亮的景点也折腾的不成样子了,儿童乐园、麦香村等商店有时一个人也没来,最后只好倒闭。人们在家里没事做,快闷死了,小孩更是哭着闹着,大人也无可奈何地唉声叹气。
我想着想着,不禁大叫:“人们,不要再污染环境了,这样下去我们怎么受得了啊!”一旁的农民说:“你说的倒好,草杆不焚烧怎么行?”我愤愤不平道:“谁能发明一个自动焚烧器多好呀,焚烧的又好又不污染环境,照这样下去,世界真变得不知成啥样子了!”农民嘲讽道:“你来发明呀,你发明出来,我把全部家当送给你!”“我一定能发明的出来!”“你试试呀!”我大声叫道:“我长大了一定要发明一个!”
说完,我转身和家人一起上了长途汽车,车开远了,农民们还在后面嘲笑:“输了吧……”

篇13:工厂对环境的污染作文
全文共 804 字
+ 加入清单近几十年来不断发展的科技使一部分人用它制造的对地球环境大大有害的没有经恰当处理过的工业废弃物的量开始以几何速度增长。
一百年前左右,这地方的工业废弃物对环境所造成的伤害还远不如现在那么严重------大部分的地方空气的API指数很低。而如今,一些大型工厂在工作时产生的很多二氧化硫与空气颗粒和汽车排放的尾气对空气也形成很大污染,会破坏大气层,导致酸雨形成,而且人吸入这种空气以后对身体也有很大影响,种种症状出现的可能性也大大地增加了。所以这类物质对整个地球实在是伤害不轻。另外,数以万斤计的相对来说对环境造成的伤害极大的垃圾如废电池、塑料袋、水银温度计、过期药品等正在被不断地成堆成堆地置于一些垃圾场,导致严重的土地污染,使那边周围树木花朵等植物无法生长,耕地也成为了不可能的事情。不仅如此,在那里工作的人们也会受到影响,导致身体状态不好。我经过一些施工地区与工厂的时候,一般都会问到一股燃烧过的橡胶产生的味道,很难闻。这也是一种有害气体。还有一些比燃烧橡胶更难闻的空气,似乎是重金属物质产生。我每逢这种情况都是快快走过,但就是这一分钟都不到的呼吸这种空气已使我感到头有点晕。而在里面工作的工人要天天不断地呼吸这种空气几个小时,这对人体伤害该有多大啊!
以上只是工业在大气层内对空气与土地形成的污染给人类带来的影响------大气层外“报废”了的卫星无规则地漂浮在地球附近会使人类发射的火箭有可能与之相撞导致损伤,使人类对外太空进行顺利的探索的难度增加。而且对于其中一部分来说,清除它们也不是一件容易之事------一些“报废”已久的卫星已碎成碎片,四处飘浮,要发射新的卫星去将它们“一网打尽”地回收很难。形成这种情况的原因是人类没有设定精密仪器来检测他们是否报废从而在他们报废的第一时间发射卫星将它们回收。
以上都是人类没有恰当地处理工业生产中所产生的衍生物。所以,读者,请恰当地处理你手中的工业产品及其衍生物。

Individuals can do nothing to improve the environment; only governments and large companies can make a difference. To what extent do you agree or disagree?
范文
Nowadays, an increasing number of people are concerned about environmental protection and regard it as one of the most important challenges. However, whether only governments and big firms have resources and powers to preserve our environment is a controversial issue. My view is that every single citizen could also make a huge difference.
In the first place, it is clear that it is human activities that have the greatest impact throughout the history. Both environment contamination and conservation are the long-term process, and no single government or big company can meet this challenge alone. So whoever created the problem should be responsible for solving it; environment protection needs every one of us to continuously participate in.
Moreover, the publics wills and behaviors have critical influence on governments policies and companies strategies. For example, if everyone says no to plastic shopping bags and paper cups, the companies that manufacture such products will switch to environmental-friendly substitutes in order to survive in the market.

+ 加入清单如果你跟我去春游,你就会发现我们带走的是难得一见的喜悦,而留下的是遍地的塑料袋随处可见,小溪里,树梢上,草地上...... 塑料袋飘来飘去,不仅污染了环境,而且又影响了美观。
其实塑料袋对环境有很大的危害,土壤里有塑料袋,便会影响农作物对水分、养分的吸收,抑制农作物的生长发育,如果用火焚烧塑料袋会出现大量有毒气体,会污染大气,对环境有着不可估量的危害。如果填埋塑料袋会污染水土,要将近两百年的时间才会被分解;牛羊吃了还会生病甚至死亡......
现在以塑料袋为主的“白色污染”越来越严重了。近年来,由于大量废旧包装塑料膜,塑料袋使用量激增,并且任意乱扔,各大城市都形成了严重的“白色污染”。
作为小学生,我们能做些什么呢?我觉得我们应该以身边的小事做起;在春游外出的时候,尽量不要用塑料袋,用自己的书包或纸袋带一些物品;买早点的时候,尽量带好自己的碗,不要商家提供塑料袋打包;我们还要劝身边的大人,买菜、购物的时候尽量使用环保袋和菜篮子,如果确实需要,我们要使用国家推荐的可分解的环保塑料袋。我倡议:拒绝使用塑料袋,像“白色污染”说再见。如果我们大家人人都这样做的话,那么我相信地球一定会变的更加美丽,我们的生活环境也会变的更加美好和舒适。

people often think that water will never be used up. there is plenty of water, such as rain, water from the rivers and wells. it seems as if water is always available around us and we never have to worry about water shortage.
in fact water is rather limited on the earth. with the rapid increase of population and fast development of industries, water is more needed than before. at the same time, a large amount of water has been polluted and wasted every day. some big cities in china are facing the problem of water shorage already. there, water supply is controlled and industry has been restrained.
what should we do about the water shorage? i think, first, the people should be made aware of the real situation about the water. everyone should consciously save on water and certain law should be made that no water will be polluted. we have to protect the existing water resources and develop new ones. in this way i believe that our cities will not be thirsty for water in the future.
篇18:汽车污染环境的作文
全文共 1145 字
+ 加入清单在我们的家乡,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?

其实在我们生活中有许多小细节对环境的保护有很大的帮助,比如:买菜不用一次性塑料袋,在外面吃饭不用一次性碗和筷子,还有我们用的铅笔要用可以换笔芯的那总等等······
保护环境人人有责,让我们一起保护环境保护我们的家园,让我们的家园越来越美丽。
环境污染的作文二
“地球上的最后一滴水将是人类的眼泪。”这是哲夫先生的一句名言。它准确的告诉我们水资源的重要性,同时也告诉我们保护环境的重要性。
随着科技的发展,人类的生活条件在一天天提高,而人类的生活环境在一天天下降。这是因为人们随意乱扔垃圾,排放废气,这些垃圾和废气既污染了环境,也造成了许多有害物质,让人类的身体和生活受到了严重的危害。
我们既然生活在这个星球上,那我们就不这个星球上的一部分,我们应尽我们的力气去保护它,不要让它受到伤害。
我们在乱扔垃圾时,又可曾想到,我们破坏了生态;我们在排放废气时,又可曾想到,这让人们的身体受到了严重危害,环境也曾因此会被严重污染。当我们破坏生态时,又可曾想到,地球妈妈正在哭泣!
保护环境也是在保护自己,只有我们保护好环境才可以在这个星球上快乐的生活,如果我们一味的伤害大地,污染环境,那么我们终有一天也会受到大自然的惩罚。
环境污染的作文三
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。这不是最好的证明吗?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!

汽车尾气污染环境作文一
我是一名农村小学四年级的学生,经常生活在农村里的我,对省城——西安的模样一无所知。在春节里,爸爸、妈妈决定把我带到西安去游玩。正月初六那天,我们一家人兴高采烈的出门了。初春的阳光照在我们身上感觉格外舒服。到了西安城,我看见在车水马龙的城市里,一股股浅蓝色的烟气从一辆辆机动车尾部喷出,呛得我睁不开眼睛,甚至感觉有点头昏。爸爸说:“这就是我们所说的机动车尾气,它的颜色怪异,而且气味令人头昏、恶心,神不知鬼不觉地影响人的身体健康。”妈妈又接着说:“汽车作为陆地上最主要的交通工具,它已经成为现代社会文明的标志。但汽车所排放的尾气已对大自然和人类造成及其严重的危害。”听了他们的话,我心里沉甸甸的,作为一名小学生,长大后能不能变废气为宝呢?
回到家后,我开始思索着。我在家里纸上画一画,结合我们日常的生活用品,我想研制一种新汽车,安装汽车尾气能量回收利用的空调装置,不但回收利用了汽车尾气的能量,还节省了能源,同时使汽车有空调器制冷的效果,降低汽车空调的生产成本,这种汽车尾气利用装置可安装在汽车轮子不同位置。
新装置安装在汽车排气管上,利用尾气与空气间温差导致的热效应,形成电能,我们可以利用尾气来发电,通过电动机驱动汽车。多余的电能,可以接到在家里,就可以节约燃料,减少用电量,真的是一举多得呢。也可以安装尾气净化装置,把有毒的尾气转换成氧气,也可以根据个人的爱好转换成各种各样的香气。
为了我的新装置能早些给人类带来福音,从现在起,我要更加勤奋学习,学习更多的科学知识,掌握足够的本领,实现更多的梦想。
汽车尾气污染环境作文二
每年有越来越多的汽车在新车的人数以百万计的生产道路。出六个一工程美国人制造汽车,驾驶卡车,修建道路或填补气体。美国人不能没有车!
大多数美国人将很难想象没有汽车的生活。然而,一些已经认识到空气污染严重的问题,汽车造成的。污浊的空气变成有毒的和危险的健康。
一个办法让污浊的空气,就是自己做,无污染的汽车。但要建设一个清洁汽车谈何容易。在这一领域的进展非常缓慢。
另一种方法是别的东西取代汽车发动机。发明者现正蒸汽汽车以及电动汽车。许多厂商认为,这将需要几年发展为我们实践模式。
为了防止世界被污染的汽车,我们要在我们的生活有所改变。例如,美国,不得不削减对它们的总人数下降cars.They鼓励使用自行车,这被认为有助于保持空气清洁。
但是,这一变化来之不易。阿大批工人可能会发现自己没有工作,如果汽车厂cioses了。因此,空气污染问题将变得并不重要,重要的失业问题。虽然汽车已使我们更好的生活,他们也给我们带来了新的问题。
