    2.由于附近金礦生產(chǎn)廢棄物尾礦砂的堆積,孫家村的大溝里十幾年來就吃掉了近百畝土地,使人均耕地下降到0.03公頃。村里和礦上共同商量,共同開發(fā)復墾,由礦上出錢,村里出勞力、機械,運來“客土”覆蓋到尾礦填平的溝壑上,形成耕地。十年來,通過這種方式恢復耕地15.335公頃,不僅解決了尾礦污染問題,而且村里耕地由25公頃多增加到40公頃。【思考】分析以上兩個例子,哪一個體現(xiàn)了可持續(xù)發(fā)展的原則,為什么?【分析】第二個材料體現(xiàn)了可持續(xù)發(fā)展。因為材料1用農(nóng)田堆放垃圾會破壞土地肥力,影響農(nóng)業(yè)生產(chǎn),又污染環(huán)境,危害村民健康。這種行為目光短淺,只顧眼前利益,沒有考慮長遠發(fā)展。材料2既解決了尾礦污染問題,又增加了耕地面積,耕地是可再生資源,利用得當,可為村民提供農(nóng)產(chǎn)品,解決溫飽同時創(chuàng)造經(jīng)濟效益,達到良性循環(huán)。所以說保護環(huán)境就是挽救人類,我們要將這種意識轉(zhuǎn)化為自身行為,使人地關(guān)系走向和諧。
