With the progress of science and technology and the development of the times, a new era of developing the ocean has arrived. In the process of developing the ocean, people get more wealth from the ocean more effectively. Many countries have established undersea pastoral areas and undersea pastures, and people are gradually transitioning from the era of simple marine fishing to the era of "cultivating the ocean". People work better and more effectively in underwater pastoral and underwater pasture than in agricultural pasture on land, because the output of marine farming is 100 times higher than that of land farming in the same area. People will breed seaweed and seaweed in large quantities as feed for cattle, pigs and sheep on land, so as to get more protein. The total output of underwater rural areas in the world has jumped from 20 million tons to 50 million tons, and a large number of seaweed and seaweed will also be harvested by underwater combine harvesters. Not only that, people also built "underwater cities". A group of Japanese engineers and architects built the world's first "marine city" in the sea area 0/20km away from Tokyo/Kloc. In addition to residential areas, there are 1 business center, 400 tennis courts, 8 golf courses, 2 baseball fields, 1 artificial fields for growing fruits and vegetables, and roads connecting vertically and horizontally. At this time, the deep seabed will no longer be silent and become as lively as the mainland.

More and more people will explore and build the ocean and paint this grand blueprint with their wisdom and hands. The future of the ocean shows people brilliant prospects, and the vast ocean will make great contributions to mankind.
