  • 保護環境珍惜地球——演講稿

    時間:2018-02-08 07:21:06來源:<推薦訪問:環保演講稿

    同學們:
      我今天發言的主題是《保護環境,珍惜地球》。
      我們生活在地球上,因為她是我們唯一能生存的地方。我們離不開陽光,離不開植物,離不開氧氣,也離不開水。
      可是同學們知道嗎?地球這位母親的身上的綠,正一點一點地變黃,科學家們測算,在不久的將來,母親的綠色會消失,我也曾作過一個真實的夢,夢見全球已被沙漠化,一眼望去,只能看見無邊的沙子和黑色的天空,而我向一架飛船走去……
      可是同學們知道嗎?母親將面臨一場災難----全球氣候變暖,南北極冰雪融化,海平面升高,大地淹沒,南極上空出現臭氧空洞,空氣一點點的流逝,動物大量滅絕……
      可是同學們知道嗎?我們可以直接利用的水只占世界總水量的十萬分之七,可以說是微乎其微。可是這些水害不斷地被污染著,大地上水的顏色,正不停的變換著……
      我前幾天看電視得知,在長江里,中國獨有的中華鱘已經絕種,令幾十代中國人自豪的活化石已從我們眼前消失。
      我有一個愿望,我要一個三色地球,水是藍色的、大地是綠色的、云是白色的,森林覆蓋率是百分之百,藍天和白云和諧的搭配著,只有誘人的綠色的大地。
      讓我們保護環境,珍惜地球,不讓最后一滴水是人們的淚水,最后一口氣是人們呼出的二氧化碳。為三色地球而努力學習吧!
