關(guān)于環(huán)境污染的作文1
如今,科技已經(jīng)越來(lái)越發(fā)達(dá)了,但是,我們也不可以忘記環(huán)保生活。
現(xiàn)在,環(huán)境已經(jīng)受到了嚴(yán)重的破壞。
曾經(jīng),一條條清澈見(jiàn)底的小河,變成了一條臟兮兮的小河,河邊的青草,花兒也因?yàn)榕K兮兮的小河而枯萎了;河里的小魚(yú)小蝦也因?yàn)楹铀年P(guān)系而無(wú)家可歸。
曾經(jīng),一片茂密的森林,卻變成光禿禿的一片荒地,許多小動(dòng)物無(wú)家可歸。如果沒(méi)有了樹(shù)木,沙塵暴來(lái)了,我們?cè)趺崔k?
曾經(jīng),廣闊、湛藍(lán)、寧?kù)o的天空,變得不再那么美麗,因?yàn)橐恍┕S排放污空氣,股股黑煙飛上那湛藍(lán)、寧?kù)o的天空,使天空變得不再那么美麗了。
可愛(ài)的小動(dòng)物被人類亂捕亂殺,使人類的朋友遭到涂炭。難道真的要“千山鳥(niǎo)飛絕,萬(wàn)徑人蹤滅”人類才肯收手嗎?我們應(yīng)該要保護(hù)好動(dòng)物,因?yàn)楸Wo(hù)動(dòng)物就是保護(hù)我們自己。
要保護(hù)好環(huán)境其實(shí)并不困難。
外出郊游或出遠(yuǎn)門的時(shí)候我們可以少開(kāi)私家車,多坐大巴,這樣可以減少對(duì)環(huán)境的污染;節(jié)約用水和節(jié)約用電,減少對(duì)環(huán)境的污染;養(yǎng)成垃圾分類的習(xí)慣,有些垃圾是可以循環(huán)利用的;不亂砍伐花草樹(shù)木,俗話說(shuō)得好“留得青山在,不怕沒(méi)柴燒”,傷害大自然就是傷害我們的子孫后代呀!
地球,是我們?nèi)祟惖募摇?/p>
地球,給了我們藍(lán)天白云,給了我們江河湖海,給了我們森林和草原,也給了我們賴以生存的的空氣。這顆蔚藍(lán)色的星球是茫茫的宇宙中唯一可以讓人類生存的家園。然而,隨著科學(xué)技術(shù)的發(fā)展,各種五花八門的生活垃圾越來(lái)越多,其中大多數(shù)垃圾都是會(huì)造成環(huán)境污染的。比如說(shuō)我們常用的電池,如果用完后不進(jìn)行適當(dāng)?shù)奶幚恚敲磳?huì)造成極大的環(huán)境污染。據(jù)研究,一節(jié)廢的紐扣電池能使60萬(wàn)升的水不能飲用。如果每人丟棄一顆廢電池,那么到了那時(shí),水,將成為奢侈品。
同住地球村的我們,醒醒吧!不要再去破壞地球了,我們應(yīng)該從現(xiàn)在做起,從小事做起,保護(hù)環(huán)境!
同學(xué)們,保護(hù)環(huán)境的小事莫過(guò)于在學(xué)校,如果你看到那個(gè)水龍頭在傷心地流淚,請(qǐng)你去安慰它,把它擰緊。如果放學(xué)時(shí),你看到電燈還沒(méi)能休息,請(qǐng)你把燈關(guān)上,也讓它休息休息。如果你在劃船時(shí),不把垃圾丟到水里,就是給魚(yú)兒一個(gè)舒心的家……只要我們大家一起努力,做環(huán)保好心人,魚(yú)兒就會(huì)在水里暢游,鳥(niǎo)兒就能在林中高飛。人們也能在這片土地上快樂(lè)地生活。
同學(xué)們,我們應(yīng)該保護(hù)好環(huán)境,讓青山變得更蒼翠,河水變得更清澈,天空變得更蔚藍(lán)吧!只要我們保護(hù)環(huán)境,就能為建設(shè)美好家園出一份力。我相信,在大家的努力下,地球的明天一定會(huì)因?yàn)橛腥祟惖拇嬖诙兊酶用篮?

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.

隨著地球資源的漸漸減少,呼吁環(huán)保的呼聲日益增多。但是仍有大部分的人類肆意的破壞著生態(tài)平衡。有人高呼環(huán)保,背地里卻干著見(jiàn)不的人的勾當(dāng);有的廠家對(duì)外宣稱“合理排行污水”,卻把江河當(dāng)做污水排放廠······隨著人類社會(huì)的高度發(fā)展,人類已進(jìn)入了空前的文明時(shí)代,但我們面前的卻是烏黑發(fā)臭的河水,成片的沙漠,光禿的土坡,作為90后的我們,應(yīng)該把環(huán)保做的更好。
白色污染
伴隨著人類生活文明的進(jìn)步,白色污染日愈嚴(yán)重起來(lái)。塑料袋,塑料包裝等雖是我們?nèi)粘I钪斜夭豢缮俚臇|西,它價(jià)格便宜,質(zhì)輕,耐用,防水的幾大特點(diǎn)被人們所看好。在中國(guó)的市場(chǎng)極大,我國(guó)也是世界上十大塑料制品生產(chǎn)和消費(fèi)國(guó)之一。但處理這些東西比想象中難得多。一般塑料垃圾在自然界“停留”的時(shí)間可達(dá)200——500年。所以對(duì)于塑料類制品我們要抵制使用。
汞污染
汞是唯一在常溫下呈液體的金屬元素。俗稱“朱砂”。汞可溶于水,空氣中。它巨大的毒性令人談之色變。它主要來(lái)源于電池等物品。據(jù)統(tǒng)計(jì)1970——1979年全世界直接向水體排放的汞總量達(dá)1.6萬(wàn)噸!排向大氣的汞量也達(dá)10萬(wàn)噸。當(dāng)水中或空氣中的'汞濃度過(guò)高時(shí),會(huì)導(dǎo)致樹(shù)木枯死,人類患上因汞攝入過(guò)高引發(fā)的病癥,如日本南部九州灣有一個(gè)叫水俁的小鎮(zhèn),這里居住著4萬(wàn)居民,以漁業(yè)為生。1939年開(kāi)始,日本氮肥公司的合成醋酸廠開(kāi)始生產(chǎn)氯乙烯,工廠的生產(chǎn)廢水一直排放入水誤灣。該公司在生產(chǎn)氯乙烯和醋酸乙烯時(shí),使用了含汞的催化劑,使廢水中含有大量的汞。這種汞在水體中,被水中的魚(yú)食用,在魚(yú)體內(nèi)轉(zhuǎn)化成有毒的甲基汞。人食用魚(yú)后,汞在人體內(nèi)聚集從而產(chǎn)生一種怪病:患者開(kāi)始時(shí),只是口齒不清,步履蹣跚,繼而面部癡呆,全身麻木,耳聾眼瞎,最后變成神經(jīng)失常,直至躬身狂叫而死。1972年據(jù)環(huán)境廳統(tǒng)計(jì),水誤鎮(zhèn)共患水誤病180人,死亡50多人,就在新線縣阿赫野川亦發(fā)現(xiàn)100多水誤病患者,8人死亡。據(jù)報(bào)到,患者人數(shù)遠(yuǎn)不止此,僅水誤鎮(zhèn)的受害居民,即達(dá)萬(wàn)余人。
環(huán)保事業(yè)說(shuō)大很大,說(shuō)小很小。往大的說(shuō),可以造成成片的水域污染。往小了說(shuō),只要我們每人從身邊的小事做起,人人環(huán)保低碳,環(huán)保事業(yè)也可以是一件很小的事。如果我們少用些塑料袋,少亂丟些垃圾,那么這個(gè)世界上便會(huì)少些隨風(fēng)飄舞的白,多些生機(jī)勃勃的綠;也會(huì)少些烏黑骯臟的河,多些碧藍(lán)清澈的湖······
如果我們每個(gè)人在地上看見(jiàn)一個(gè)塑料袋不是直接走過(guò),而是彎腰拾起;如果我們每人不是隨意亂丟垃圾,而是做到合理分類垃圾;如果我們每人都少用些塑料袋,多用些環(huán)保袋。那么我相信地球母親會(huì)少些憤恨的淚水……
保護(hù)環(huán)境,從我們身邊做起!
