What will the future look like for the ocean, the last frontier of mankind on earth?
With the advancement of science and technology and the development of the times, a new era of ocean development has arrived. In developing the oceans, people will extract more wealth from them more efficiently. More and more countries are planning to establish or have already established undersea gardens and undersea pastures. People are gradually transitioning from the past era of simple ocean fishing to the future era of "farming the sea". In the not-too-distant future, people will work better and more efficiently in undersea gardens and pastures than in farms and pastures on land, because the unit output of ocean aquaculture is higher than that of land cultivation for the same area. 100 times. People will cultivate large quantities of seaweed and seaweed to supply cattle, pigs, sheep, etc. on land as feed, thereby obtaining more protein. The total output of the world's underwater gardens will soon jump from the current 20 million tons to 50 million tons. , a large amount of seaweed, seaweed, etc. will also be harvested by underwater combine harvesters, and then hoisted to the ship by steel cables.
In the near future, the fishing nets that people have used for fishing for generations will be replaced by powerful water-absorbing devices that use light emitted by electric fields, sounds of a certain frequency and special compounds dissolved in the water to lure and The fish are forced to gather together and swim close to the suction pipe placed on the boat. The suction pipe sucks the water and fish into the cabin together. By then, together with the various fish and shrimps provided to humans by seabed pastures, the seafood that people obtain from the ocean will reach more than 1 billion tons, which is more than ten times or even dozens of times more than what is currently demanded from the ocean.
As the world’s demand for oil, natural gas and other resources continues to grow and people exploit these resources in large quantities, these resources on land will become increasingly depleted. People are bound to turn their attention to the ocean or find new energy sources. It is estimated. The oil reserves on the seabed are about 90 billion tons. The oil reserves in the Arctic Ocean alone can last the world for 50 years. At present, more than 100 countries and regions have carried out continental shelf and deep-sea oil exploration and exploitation, and more than 500 oil and gas fields have been discovered. The implementation of a ten-year world ocean edge drilling plan is nearing completion. Explore and exploit seabed oil and build production bases on the seabed. For transportation problems after submarine oil is extracted, large submarines will be used. Imagine sinking a giant plastic cylinder to the bottom of the sea, loading it with 100,000 tons of crude oil, and towing it by a submarine. Some people also design to use spaceships for shipment.
There is huge energy in the ocean, which people call the "blue sea of ??coal", which will be converted into energy for the future of mankind. Future ocean thermal energy conversion plants will be set up in the sea, and cables can be used to supply urban electricity along the coast. Heavy water, known as the "fuel of the future," has a much higher content in seawater than in land water. Isotopes of hydrogen can be extracted from heavy water, and scientists are using it to conduct thermonuclear reaction experiments. If successful, it will become an inexhaustible energy source.
In the not too distant future, people will build "undersea cities". This is no longer a fantasy, but a reality. At present, Japan has built a "small city" for maritime swimming for Arab countries. It is mostly made of steel and has a 6-story building in the center. It has an indoor small garden, a cinema, and all water and electricity are supplied by itself. It can meet the cultural and entertainment needs of offshore oil production workers. This floating "city" is held up by eight tall pillars. When they are stowed away, they can be used as a boat. In the future, many offshore factories will be built in sea areas near raw material production areas or markets to provide material needs for residents of maritime cities. There is a "Sea Park" in Ryukushi Bay in the southwest of Shikoku Island, Japan. People can enjoy the wonders of the sea through 16 glass windows with a diameter of 60 cm: strange-shaped reefs, colorful corals, and all kinds of strange and beautiful things. Fish and interesting starfish, sea anemones, etc. Since the United States was the first to build an underwater laboratory, many countries have followed suit and built "steel houses" and other buildings on the seabed. The air pressure inside the "house" is the same as that on the sea surface. People can work normally inside and repair submarine oil and gas. Wells, salvaging sunken ships, seabed exploration or supplying submarines, etc. It is also reported that a group of Japanese engineers and architects. It is planned to build the world's first "Ocean City" on the sea 120 kilometers away from Tokyo to solve the problem of human settlement in the future. Ocean City will be built on the seabed 200 meters deep. It will have a 4-story steel platform, about 70 meters above the sea, covering an area of ??23 square kilometers. The whole city will be supported by 10,000 solid straight columns. Sensing device.
It can detect typhoons, tsunamis and undercurrents, and adjust its strength to resist these external pressures and maintain the stability of Ocean City. In addition to the residential area, Ocean City also has a commercial center, 400 tennis courts, 8 golf courses, two baseball fields, an artificial field for growing fruits and vegetables, and connected roads. The construction cost of Ocean City is estimated to be US$200 billion, and this huge project is expected to be completed by the end of this century. By the 21st century, this "undersea city" will be home to more than 10,000 people. At that time, the deep seabed will no longer be silent, but will become as lively as the mainland. More and more people will explore and build it. , use your own wisdom and hands to draw this huge and magnificent blueprint.
The future of the ocean shows people a brilliant prospect. The vast ocean will make huge contributions to mankind.
