古今中外的历史事实证明,土壤侵蚀不会带来繁荣,最终将导致灾难。古罗马帝国因风蚀沙化毁掉了北非的粮食;近50年来,沙化导致撒哈拉沙漠多次南侵,迫使邻近国家不得不放弃大片宜农宜牧的土地;美索不达米亚、希腊、小亚细亚毁林开荒造成流失,使无数耕地变成不毛之地;西班牙种植场主在古巴焚烧山林种植咖啡,最终使沃土流光,变成赤裸裸的石山;1934年美国发生巨大的“黑风暴”,横扫美洲大陆,给美国人民带来了莫大的灾难。土壤侵蚀不仅对饱受其害的亿万人民和国家是一个严重的问题,而且在世界人口迅速增长需要有更多土地提供更多食品的今天,已成为一个世界性的问题。
The historical facts at all times and in all countries show that soil erosion will not bring prosperity and will eventually lead to disaster. For the past 50 years, desertification has led to the destruction of North African food due to wind erosion and desertification. In the past 50 years, the desertification led to numerous southward sub-Saharan invasions, forcing neighboring countries to abandon large areas of land suitable for farming and animal husbandry. Mesopotamia, Greece and Asia Minor were destroyed The loss caused by forest wasteland has turned innumerable cultivated land into barren land. Spanish planters planted coffee in the forests burned in Cuba, eventually turning the fertile soil into naked stone mountains. In 1934, the United States experienced a huge “black storm” sweeping the continent , Has brought great disaster to the American people. Soil erosion is not only a serious problem for the hundreds of millions of people and countries that suffer from it, but today the world population needs more land to provide more food due to the rapid growth of the world population. It has become a worldwide problem.
