大自然为我们人类提供了优良的生存环境和优越的生活条件。其中,那肥沃的土地、丰富的矿产、茂密的森林和重要的水资源都是大自然贡献给我们的。大自然为我们贡献了如此之多,我们又回报了些什么给这个无私的“母亲”呢——是那毫无节制的砍伐、放牧,还是那贪得无厌的捕杀? 自然资源并不是“取之不尽,用之不竭”的。我们的母亲河——黄河自20世纪70年代到90 年代就年年断流,对下游的生态环境产生了重大的影响。这是为什么呢?这还不是因为我们人类吗?我们在黄河上、中游的河段乱砍树,严重的破坏了植被,导致水土流失,甚至还产生了荒漠化。
Nature has provided us with an excellent living environment and superior living conditions for us. Among them, the fertile land, abundant minerals, dense forests and important water resources are all contributed by nature. Nature has contributed so much to us, and we have repaid something to this selfless “mother” — whether it is uncontrolled deforestation, grazing or insatiable killing. Natural resources are not “not taken from it.” Do everything, inexhaustible. Our mother river, the Yellow River, was cut off annually from the 1970s to the 1990s, which had a major impact on the downstream ecological environment. This is why? Is this not because of our humanity? We have cut trees in the upper and middle reaches of the Yellow River, severely destroying vegetation, causing soil erosion and even desertification.
