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(fù)墾，由礦上出錢，村里出勞力、機(jī)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(fù)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(yuǎn)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(dāng)，可為村民提供農(nóng)產(chǎn)品，解決溫飽同時創(chuàng)造經(jīng)濟(jì)效益，達(dá)到良性循環(huán)。所以說保護(hù)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。
