                [小學3-4年級]愛護環境


                很久很久以前,數百年前,我們的家園鳥語花香,綠意盎然,雖然沒有現代科技那么發達但是空氣清新環境優美。現在,交通發達了,代步工具由汽車取代了馬匹,各種工廠,相繼誕生。戰爭,從冷兵器轉向了火藥、核武器。我們的地球日益污染嚴重,由于中國人口多,現在淡水極度缺乏,如果把地球上所有的水比作一桶水那么我們人類可以用得水只有一勺,可想而知這是多么可怕。
                現代有些人為了謀取利益不惜一切代價,來砍伐森林污染河流將來人們的生活環境就算不為自己考慮,也應該為子孫后代著想啊。
                現在地球越來越暖,等到南極北極融化,那是多么可怕的后果。那時候地球就真的變成了一個水球。
                所以現在我們要保護地球保護環境、節約用水。極力宣傳愛護自己的家園,從我做起,從身邊做起。
                讓更多人知道地球是人類現如今唯一的家園。

                范文2:有關保護環境的作文600字


                人類只有一個地球,它是人類賴以生存的自然資源,人們要過上幸福美好的生活,就必須自覺地保護自然環境,愛護地球。

                然而,近幾年來,地球的環境卻越來越惡劣:全球性氣候變暖,颶風、暴雨等災害性天氣頻繁出現,“非典”、禽流感等傳染性疾病時有發生,給人類的生活和工作帶來嚴重威脅和許多不便。這些都是人們不斷地“傷害”地球的結果。大片的森林被砍伐,碧綠的青山被挖掘,美麗的草原成荒漠,清澈的河水成濁流。樹林少了,青山禿了,草原荒了,清水黑了,使人們生存的環境變壞,呼吸的空氣變差,生活的環境被許多有害的東西所“侵占”,病毒就趁機鉆進人們的體內,我們人類就會患上一些可怕的疾病。

                前幾天,我在報紙上看到這樣一幅漫畫:一個人坐在樹梢上,正在砍他坐著的那根樹枝。“哼,真好笑。”有些人可能會這么想。難道你就沒有想一想,這僅僅是幅好笑的漫畫嗎?它不正是在諷刺我們嗎?難道你就沒有悟到,它在警告我們:人類在破壞環境的同時,也在不知不覺地傷害自己。

                當你走在大街上,如果你想吐痰,你會怎么做呢?如果你選擇了吐在地上,那么你想過沒有,你在害自己嗎?一口痰含有大量的病菌,當太陽著時就會繁殖、傳染。同樣,當你砍伐一棵樹,當你挖掉一片草,當你把臟物倒進河流,難道你沒有覺得這是在破壞環境,“傷害”自己嗎?

                俗語說得好:“前人栽樹,后人乘涼”,前人給了我們大片大片的森林,綠地,我們留給后人的是什么?是光禿禿的荒漠,還是茂密的樹林,你肯定選擇的是茂密的樹林。那還有什么猶豫的,讓我們大家一起自覺保護環境,自覺愛護環境,自覺綠化環境,改善我們的生活環境,創造美好的未來!
