It is self-evident that the Earth has a lot of water // enough to make a farmhouse the size of the continents combined.  Moreover, compared to the average altitude of the land / w, the average depth of the ocean is 3734 meters.  As such, the volume according to the surface/depth is of course more expansive.  / That's all water in its volume, but in this water-rich earth, we have less than 2 percent of the tower water we can use.  This is because 97 percent of the 41 to 41 percent of the rest is the only network that requires the application of seawater desalination technology.  Some argue that the results of engineering studies should be applied to slow the rise in displaced sea levels.  Actually, (Nature> introduces a method of drying or freezing the water on the land ice floor to prevent the movement of glaciers, and to increase the intellectual power of Byeongbong by constructing an artificial island offshore.  The answer is in the sea If seawater desalination technology is further developed, it is possible to supply water to the world, so you probably don't have to worry about water shortage.  1 All of these arguments have a geoengineering perspective, which suggests that we will intervene a little more actively in light matters and use them as drinking water in addition to those artificial waters, and further control today's raw Nanjing.  It is recommended to take a closer look at the global environment than to know more about the global environment. Even the scientific giant garbage problem about the global environment can also have the childish side effects of ocean cleanup using ocean currents.  A levee to prevent the Antarctic heartworm was also proposed, which would lead me to continue living on the only planet.
