关于环境污染的作文
如今,科技已经越来越发达了,但是,我们也不可以忘记环保生活。
现在,环境已经受到了严重的破坏。
曾经,一条条清澈见底的小河,变成了一条脏兮兮的小河,河边的青草,花儿也因为脏兮兮的小河而枯萎了;河里的小鱼小虾也因为河水的关系而无家可归。
曾经,一片茂密的森林,却变成光秃秃的一片荒地,许多小动物无家可归。如果没有了树木,沙尘暴来了,我们怎么办?
曾经,广阔、湛蓝、宁静的天空,变得不再那么美丽,因为一些工厂排放污空气,股股黑烟飞上那湛蓝、宁静的天空,使天空变得不再那么美丽了。
可爱的小动物被人类乱捕乱杀,使人类的朋友遭到涂炭。难道真的要“千山鸟飞绝,万径人踪灭”人类才肯收手吗?我们应该要保护好动物,因为保护动物就是保护我们自己。
要保护好环境其实并不困难。
外出郊游或出远门的时候我们可以少开私家车,多坐大巴,这样可以减少对环境的污染;节约用水和节约用电,减少对环境的污染;养成垃圾分类的习惯,有些垃圾是可以循环利用的;不乱砍伐花草树木,俗话说得好“留得青山在,不怕没柴烧”,伤害大自然就是伤害我们的子孙后代呀!
地球,是我们全人类的家。
地球,给了我们蓝天白云,给了我们江河湖海,给了我们森林和草原,也给了我们赖以生存的的空气。这颗蔚蓝色的星球是茫茫的宇宙中唯一可以让人类生存的家园。然而,随着科学技术的发展,各种五花八门的生活垃圾越来越多,其中大多数垃圾都是会造成环境污染的。比如说我们常用的电池,如果用完后不进行适当的处理,那么将会造成极大的环境污染。据研究,一节废的纽扣电池能使60万升的水不能饮用。如果每人丢弃一颗废电池,那么到了那时,水,将成为奢侈品。
同住地球村的我们,醒醒吧!不要再去破坏地球了,我们应该从现在做起,从小事做起,保护环境!
同学们,保护环境的小事莫过于在学校,如果你看到那个水龙头在伤心地流泪,请你去安慰它,把它拧紧。如果放学时,你看到电灯还没能休息,请你把灯关上,也让它休息休息。如果你在划船时,不把垃圾丢到水里,就是给鱼儿一个舒心的家……只要我们大家一起努力,做环保好心人,鱼儿就会在水里畅游,鸟儿就能在林中高飞。人们也能在这片土地上快乐地生活。
同学们,我们应该保护好环境,让青山变得更苍翠,河水变得更清澈,天空变得更蔚蓝吧!只要我们保护环境,就能为建设美好家园出一份力。我相信,在大家的努力下,地球的明天一定会因为有人类的存在而变得更加美好!
The destruction of our natural resources and contamination of our food supply continue occur, largely because of the extreme difficulty in affixing legal responsibility on those who continue to treat our environment with reckless abandon . Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been net by lawsuits, personal and industrial denial and long delaysnot only in accepting responsibility, but more importantly, in doing something about it.
It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is industrys and our recognition that protecting mankinds great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now.
We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge.
We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion.
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 are still 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.
随着地球资源的渐渐减少,呼吁环保的呼声日益增多。但是仍有大部分的人类肆意的破坏着生态平衡。有人高呼环保,背地里却干着见不的人的勾当;有的厂家对外宣称“合理排行污水”,却把江河当做污水排放厂······随着人类社会的高度发展,人类已进入了空前的文明时代,但我们面前的却是乌黑发臭的河水,成片的沙漠,光秃的土坡,作为90后的我们,应该把环保做的更好。
白色污染
伴随着人类生活文明的进步,白色污染日愈严重起来。塑料袋,塑料包装等虽是我们日常生活中必不可少的东西,它价格便宜,质轻,耐用,防水的几大特点被人们所看好。在中国的市场极大,我国也是世界上十大塑料制品生产和消费国之一。但处理这些东西比想象中难得多。一般塑料垃圾在自然界“停留”的时间可达200——500年。所以对于塑料类制品我们要抵制使用。
汞污染
汞是唯一在常温下呈液体的金属元素。俗称“朱砂”。汞可溶于水,空气中。它巨大的毒性令人谈之色变。它主要来源于电池等物品。据统计1970——1979年全世界直接向水体排放的汞总量达1.6万吨!排向大气的汞量也达10万吨。当水中或空气中的'汞浓度过高时,会导致树木枯死,人类患上因汞摄入过高引发的病症,如日本南部九州湾有一个叫水俣的小镇,这里居住着4万居民,以渔业为生。1939年开始,日本氮肥公司的合成醋酸厂开始生产氯乙烯,工厂的生产废水一直排放入水误湾。该公司在生产氯乙烯和醋酸乙烯时,使用了含汞的催化剂,使废水中含有大量的汞。这种汞在水体中,被水中的鱼食用,在鱼体内转化成有毒的甲基汞。人食用鱼后,汞在人体内聚集从而产生一种怪病:患者开始时,只是口齿不清,步履蹒跚,继而面部痴呆,全身麻木,耳聋眼瞎,最后变成神经失常,直至躬身狂叫而死。1972年据环境厅统计,水误镇共患水误病180人,死亡50多人,就在新线县阿赫野川亦发现100多水误病患者,8人死亡。据报到,患者人数远不止此,仅水误镇的受害居民,即达万余人。
环保事业说大很大,说小很小。往大的说,可以造成成片的水域污染。往小了说,只要我们每人从身边的小事做起,人人环保低碳,环保事业也可以是一件很小的事。如果我们少用些塑料袋,少乱丢些垃圾,那么这个世界上便会少些随风飘舞的白,多些生机勃勃的绿;也会少些乌黑肮脏的河,多些碧蓝清澈的湖······
如果我们每个人在地上看见一个塑料袋不是直接走过,而是弯腰拾起;如果我们每人不是随意乱丢垃圾,而是做到合理分类垃圾;如果我们每人都少用些塑料袋,多用些环保袋。那么我相信地球母亲会少些愤恨的泪水……
保护环境,从我们身边做起!
