地球的表面积为51100934平方公里,其中海洋占的面积约为70.8％,约361×10~6公里~2,因此尽管人类有史以来就是从陆地寻找矿物资源,然而展望今后21世纪,随着人口的增长,粮食、能源以及原料资源的不足将是世界各国担心的问题。因此,就陆地以外的海洋而言,将来陆地不足的资源是否有可能从海洋解决, The surface area of ​​the earth is 51,100,934 square kilometers, of which the ocean covers an area of ​​about 70.8%, about 361 × 10 ~ 6 km ~ 2. Therefore, although mankind has historically been looking for mineral resources from the land, it is expected that in the 21st century, The lack of growth, food, energy and raw material resources will be a concern for all countries in the world. Therefore, in the case of oceans and seas beyond the land, is it possible for the future inland resources to be solved from the oceans and seas,
