The "Water Planet" should not be recognized simply as it was named because more than 70% of the earth's surface is dominated by oceans when observed from artificial satellites. Water exists everywhere including in the solid earth and creatures as well as in the fluid earth. The "Water Planet" is the life of the Earth itself including human beings, so we should refrain from "short-sighted" activities, which depend on conventional methods, for utilization of this planet in the new millennium.
