As we all know, the ocean accounts for seven tenths of the earth, and the marine pollution was very serious in 2002. But in 2030, due to the development of science and technology, "decontamination robots" became the bane of marine pollution, so there was no pollution problem in the ocean at that time.
Now, I'll take you to the "multifunctional reception room" and sit on the "ocean position converter", which will send us to the ocean world immediately.
Today's ocean is also the home of mankind. 50% of the people in the world live in the ocean. You must be curious. How do people survive in the ocean? In fact, there is an "oxygen control room" in the ocean world, where oxygen is produced and then transported to every corner of the ocean through an "oxygen cylinder". People inhale fresh oxygen, expel carbon dioxide, and then be received by the "oxygen control room" to make oxygen again … and so on.
The fish at the bottom of the sea are more exotic. Since the sea water became fresh water, fish learned to talk to people, and they can talk to people. Very interesting! When you meet a large group of fish, the fish will say, "Good morning!" " Incredibly, fish can also speak English.
After listening to my introduction, you will go to the residential area. Although what you see in front of you is deserted, people live here. People under the sea are different from people on land. Their food is very simple. A simple pill can last for a hundred days, so they are very leisurely. Where do you live? Take the four seas as your home, sleep wherever you want, and be carefree.
Then, when you visit palaces and parks, you will feel spectacular.
Maybe you will worry, so many people live under the sea, will there be any environmental problems? I won't. There is no factory on the seabed, but there is productive output. And it is definitely not worse than the production on land. This is because we transfer the garbage and sewage discharged from land to the "manufacturing robot" for processing, and make all kinds of useful things. ...
How about visiting the strange and wonderful sea world? I believe you will think that the power of science is so magical.

The ocean in my mind
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 will get more wealth from the ocean more effectively. More and more countries are planning to establish or have established undersea pastoral areas and undersea pastures, and people are gradually transitioning from the simple era of marine fishing in the past to the era of "cultivating the sea" in the future. In the near future, people will work better and more effectively in undersea pastoral and undersea pasture than on land, because the output of marine culture is 100 times higher than that of land farming in the same area. People will breed a large number of seaweed and seaweed as feed for cattle, pigs and sheep on land to obtain more protein, and the total output of underwater pastoral areas in the world will soon jump from the current 20 million tons to 50 million tons. A large number of seaweed and seaweed will also be harvested by underwater combine harvesters and then hoisted to the ship by steel cables.
In the near future, the fishing nets used by people for generations will be replaced by powerful water absorption devices. Using the light emitted by electric field, sound with certain frequency and special compounds dissolved in water, fish can be lured and forced to gather together and swim close to the suction pipe laid down on board, and the suction pipe will be sucked into the cabin together with the fish carrying water. By that time, people will get more than 654.38 billion tons of seafood from the ocean, ten times or even dozens of times more than what they get from the ocean now.
With the increasing demand for oil, natural gas and other resources in the world and the massive exploitation of these resources, these resources on land will be exhausted day by day. People will inevitably look to the ocean or look for new energy sources. It is estimated that the seabed oil reserves are about 90 billion tons, and the oil reserves in the Arctic Ocean alone can be used by the world for 50 years. At present, more than 100 countries and regions have explored and developed continental shelf and deep-sea oil, and more than 500 oil and gas fields have been discovered. The implementation of a ten-year world offshore drilling plan is coming to an end. Explore and develop submarine oil and build a production base on the seabed. For the transportation problem after submarine oil exploitation, people will use large submarines. Imagine sinking a huge plastic cylinder into the bottom of the sea, which is filled with 654.38+10,000 tons of crude oil and towed by a submarine. Some people also designed to transport it by spaceship.
There is a huge amount of energy in the ocean, which is called the "blue ocean of coal" and will be transformed into the future energy of mankind. In the future, the marine thermal energy conversion plant will be located in the sea, and electricity can be supplied to cities through coastal cables. The content of heavy water in seawater called "future fuel" is much higher than that in land water. Hydrogen isotope can be extracted from heavy water, and scientists are using it for thermonuclear reaction experiments. If successful, it will become an inexhaustible source of energy.
In the near future, people will also build "underwater cities", which is not an illusion, but a reality. At present, Japan has built a "small city" for Arab countries to swim at sea. Most of it is made of steel, and the center is a six-story building. There is a small indoor garden, a cinema, and all the water and electricity are self-provided. Can meet the needs of cultural and recreational life of offshore oil production workers. The floating city is supported by eight tall pillars. Put them away and you can sail like a boat. In the future, many offshore factories will be built in the sea near raw material production sites or markets to provide materials for urban residents at sea. In Longchuan Bay, southwest of Shikoku Island, Japan, there is a "park in the sea". People can enjoy the wonders of the seabed through the 60 cm diameter 16 glass window: grotesque rocks, colorful corals, all kinds of strange fish, strange starfish and anemones. Since the first underwater laboratory was built in the United States, many countries have followed suit and built "steel houses" and other buildings on the seabed. The air pressure in the "house" is the same as the sea surface, and people can work normally in it, repair oil and gas wells on the seabed, salvage sunken ships, explore the seabed or replenish submarines. It is also reported that a group of Japanese engineers and architects. It is planned to build the world's first "marine city" in the sea area from Tokyo 120km to solve the human settlement problem in the future. Ocean City will be built at a depth of 200 meters, with a four-story steel platform, about 70 meters away from the sea surface and covering an area of 23 square kilometers. The whole city will be supported by 65,438+00,000 solid columns, and induction devices will be installed near the columns. We can measure typhoons, tsunamis and undercurrents, adjust ourselves to resist these external pressures and maintain the stability of Ocean City. In addition to residential areas, Ocean City also has a commercial center, 400 tennis courts, 8 golf courses, 2 baseball fields, 1 artificial fields for growing fruits and vegetables, and roads connecting vertically and horizontally. The construction cost of Ocean City is estimated to be 200 billion dollars, and this huge project is expected to be completed by the end of this century. By 2 1 century, this "undersea city" will be inhabited by more than 1 10,000 people. At that time, the deep seabed will no longer be silent, and it will become as lively as the mainland. More and more people will explore it, build it and paint this grand blueprint with their own wisdom and hands.
The future of the ocean shows people brilliant prospects, and the vast ocean will make great contributions to mankind!

Abundant marine biological resources
With the increase of population and the development of industry, the per capita cultivated land area is gradually shrinking. The whole world is concerned about how the earth can feed human beings. The focus of attention should not be limited to further developing agriculture and animal husbandry on land, but also actively developing and utilizing the vast ocean. There are abundant biological resources in the ocean, which can not only be used to build mariculture farms, but also have many uses to be developed.
Offshore farming and animal husbandry factories have been paid attention to by all countries since 1980s. Japan first proposed to build offshore farms, and began to implement a nine-year "ocean take-off plan" from 1980 to vigorously develop marine aquaculture. By the end of 1980s, the output of aquaculture had exceeded 2 million tons, ranking first in the world. In the 1980s, the United States also invested more than $654.38 billion to build 654.38 million mu of marine farms. Although the former Soviet Union gave priority to offshore fishing, it did not relax its mariculture, throwing sturgeon larvae in the Caspian Sea and the Azov Sea, catching them when they grew up, and establishing oyster and scallop farms along the far east coast. During this period, other countries also set off an upsurge of developing mariculture. Recently, China has also paid attention to the implementation of mariculture, becoming a big shrimp farming country in the world.
Since 1980s, the world mariculture output has increased at the rate of 10% per year, and by the end of 1980s, the mariculture output was estimated to have exceeded 8 million tons. However, from the perspective of the whole marine fishery, the proportion of mariculture in the world is still relatively small, less than 10%, so there is still great potential to be developed.
Many high technologies are being used to improve fish species. For example, using genetic engineering technology to cultivate and improve the fry and larvae of fish, shrimp and shellfish to make them grow fast, have strong vitality and have good meat quality.
1984, the breeding yield of shellfish and abalone in the United States increased by 25% through gene recombination technology. According to the reasons for the discovery of growth hormone in several fish, the gene isolation and transfer experiments were carried out. 1986 successfully transferred the growth hormone gene of rainbow trout into catfish, which shortened the breeding cycle of catfish by more than half. The antifreeze gene was isolated from Antarctic fish and transferred to Atlantic salmon, which increased the cold resistance of salmon and expanded its breeding area. It is of great significance to study the sex control of fish by cell engineering and cultivate all-female salmon, prawns and all-male tilapia. At present, it is being studied to make some swimming fish respond to sound waves and light by controlling genetic genes, so as to manage it scientifically.
In addition to variety improvement, high technology is also used to build seawater farms. The establishment of artificial reefs is an example. It is to build a comfortable home for fish and attract more fish to live and multiply here. Artificial reef is to pile stones, cement blocks, waste vehicles, waste tires and so on on the seabed in various ways, thus creating an environment that marine life likes, and tiny marine life and seaweed will attach to it, providing rich bait for fish. In addition, the artificial reef protruding from the seabed will make seawater flow from the bottom to the upper layer, bring up the nutrient-rich seawater on the seabed, increase its fertility, and thus attract fish.
It is estimated that the ocean can provide 3 billion tons of aquatic products for human beings every year without disturbing the balance. Based on the global population reaching 6.3 billion in 2000, each person can get an average of 476 kilograms per year and 39 kilograms per month. Judging from the output of protein alone, the ocean can produce about 400 million tons of protein every year, which is about seven times the current demand for protein. It can be seen that the ocean can play a great role in solving the problem of human eating. Of course, this goal cannot be achieved overnight.
2 1 century marine drug storehouse
According to the prediction of relevant medical experts, human beings will subdue cancer in 2 1 century. So, what is the panacea for mankind? In recent years, scientists have found that the ocean will become a drug warehouse in 2 1 century.
Sea cucumber is a precious seafood with high protein. However, you may not have thought that several kinds of sea cucumbers will release a toxin from the anus, which has the effect of inhibiting tumors.
Oyster is a small shellfish, which is very delicious, but its greater value is because it contains antibiotics. This antibiotic has an anti-tumor effect.
At present, some drug researchers are conducting experiments to extract toxic compounds from algae and tiny marine organisms as an effective means to treat some diseases. Preliminary experiments show that toxic substances extracted from sponges can inhibit the development of cancer cells. A substance extracted from enema fish is helpful to treat diabetes. An American marine expert vividly said: "Marine life is like a consulting center, which can provide solutions to health problems."
Medical experts attach great importance to the development and utilization of coral when considering taking medicine from the ocean. Experiments show that the toxic substances extracted from coral reefs, like those extracted from some spongy creatures, also have the effect of inhibiting the development of cancer cells; Other substances extracted from coral reefs can reduce inflammation of arthritis and asthma. There is a kind of coral from Hawaii, which is very toxic and can be used to make specific drugs for leukemia, hypertension and some cancers. Soft coral purified from Nanhai, China, has the functions of lowering blood pressure, resisting arrhythmia and relieving spasm.
Shark is an ancient marine fish, widely distributed all over the world, with more than 250 species. Since the mid-1980s, many international scientists have carefully studied the pharmacology, chemistry, biochemistry and application of various parts of shark body, especially the anti-tumor active substances in shark body. According to relevant data, American biologists have investigated sharks for decades and found that sharks have almost no pathological changes and rarely get cancer, which seems to have natural immunity to cancer. Some scientists inoculate sharks with some pathogenic bacteria and cancer cells, but they can't make them sick. It seems that there are some special protective chemicals in sharks.
China experts' research on sharks is almost in step with the international research. 1985, experts from Shanghai Fisheries College and Shanghai Cancer Research Institute found for the first time that shark serum has killing effect on human erythroleukemia tumor cells in vitro. This scientific research achievement has opened up a broad world for human beings to find anti-tumor drugs from marine biological resources.
Ocean-a cornucopia of mineral resources
The ocean is a cornucopia of mineral resources. After the "international 10 marine exploration stage" in the 1970s, people's understanding of the types, distribution and reserves of marine mineral resources was further deepened.
oil and gas field
With the modernization of human economy and life, the demand for oil is increasing day by day. At present, oil occupies the first place in energy. However, because some large oil fields on land are relatively easy to exploit, some have been exhausted and some are on the verge of exhaustion. Therefore, in recent 20 ~ 30 years, many countries in the world are vigorously developing offshore oil industry.
The exploration results show that the world's oil resources reserves are 65.438+billion tons, and the recoverable amount is about 300 billion tons, of which the seabed reserves are 65.438+300 million tons.
China has a shallow continental shelf of nearly 2 million square kilometers. Through the geological survey of submarine oil fields, seven great basin, including Bohai Sea, South Yellow Sea, East China Sea, Pearl River Estuary, Beibu Gulf, Yinggehai and Taiwan Province Province Shoal, have been discovered successively. Among them, the East China Sea is rich in seabed reserves, comparable to the North Sea oil field in Europe.
