The sea is boundless and endless. Since the birth of mankind, the relationship with the ocean has been very close, and we are good friends with mankind. More importantly, the ocean is the hope of our human future. Now, we are using the energy of waves and tides to generate electricity and build a hydropower station. There are also many high-protein foods from the ocean on our human table, and we are still exploiting the mineral deposits in the ocean, which can be said to be "inexhaustible". If you refine the seawater on the whole earth, you can get 5.5 million gold, 4 billion silver and copper, 65.438+0.37 billion tons of iron ... what an amazing number! No wonder people say that the sea is a huge "blue treasure house"!

The future sea level is like a mirror, and seagulls fly freely in the sky from time to time. With the development of science and technology, people have built a "marine residential area" on the seabed and built the world's first "marine city". Look! Along the criss-crossing roads, there are high-rise buildings and dazzling commercial centers ... At this time, the seabed that I once paid no attention to will become as lively as the mainland!

I believe my future is not a dream. The future of the ocean shows people brilliant prospects, and the vast ocean will make great contributions to mankind.

The ocean of the future

In 2060, I closed the door of the underwater villa and drove a private submarine to the city center.

In 2060, 50 years after 20 10, due to global warming, all the ice layers in the north and south melted, leading to a sharp rise in global sea level. Low-altitude islands like Maldives disappeared into the sea a few years ago. Due to excessive pumping of groundwater, some continents have sunk and billions of people have become homeless. Fortunately, at this time, technology has developed to the extreme-with the help of technology, the average life expectancy of human beings is close to 300 years old. Of course, building a city under the sea is no longer a problem. Scientists predict that "continental sinking" is accelerating. By this time next year, all the land in the world will be under the sea, and the number of people moving into underwater cities will reach 2 billion.

In 20 10, the total population of the world is about 6 billion; After 2050, many humans use computers to delete the "fertility" function in the chip to save the storage space of the chip.

Anyway, there is a "fertility" function, so it is better to delete it and save space. Most humans think so. So now the total population of the world is only about 2 billion. Our last human will die in more than 200 years, and mankind will be extinct.

The submarine surfaced and the blue sea appeared in front of us. This blue color is not because it is clean and clear, but a synthetic color emitted by several chemicals, so it represents not purity, but filth. It has a strong corrosive effect on biological skin and muscles, so we must wrap ourselves up in protective clothing made of special materials to survive.

Although decades ago, human beings began to call for "protecting the environment!" But at this time, the earth has been devastated, and protecting the environment can't save everything, it can only slow down the pace of doomsday. The fish in the sea have accelerated the pace of evolution, and they can change their clothes every few months in an attempt to adapt to the seawater full of chemicals. However, they still can't keep up with the pace of Shanghai water. Every day, countless underwater creatures are corroded by seawater, leaving only skeletons, and the seabed is covered with layers of dense white bones.

Suddenly, the submarine trembled violently. No, it should be that the whole sea is shaking! The ripples on the sea surface are getting bigger and bigger, accompanied by many bubbles of different sizes. In my panic, I saw a large piece of light under the water, getting closer and closer, burning the sea like a flame, surging.

It's the collective eruption of submarine volcano! The earth that has endured for a long time is finally on fire.

I turned off the engine of the submarine and sat in a chair, and my mood suddenly calmed down. Past scenes flashed in my mind, and the most thought was one sentence: "I wonder if those who destroyed the environment rang, and the end would come so early." 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. 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. "I came to the 22nd century by time ship. In the 22 nd century, our "blue water polo" is different: 95% of the earth's area is ocean, and the population on the land is getting less and less. Is anybody there? Where have all the people gone?

"I feel very strange, how so few humans? The land has almost disappeared. Can it be said that the earth has suffered a catastrophe?

"After some investigation and understanding, I realized; It turns out that due to global warming, the sea level has risen, engulfing most of the land, and even Mount Everest is only 3000 meters above sea level. So humans built big houses on the seabed and became permanent residents of the seabed.

"I took a big ship and sailed to the sea. After a period of water, the ship began to sink and became a submersible. I saw all kinds of new buildings standing on the bottom of the sea, and fish swam freely in them. The submarine sailed for a huge building. The door of the building opened automatically and the submarine went in. Then the door closed automatically and the submarine entered a hall. Underwater objects in the hall were discharged. I was dumbfounded at once.

"I got off the boat and was greeted by a group of people wearing underwater residents' signs. They are very friendly and warmly welcome me to visit their underwater city. A very clever guide took me into the interior of this huge building. In fact, there is no difference between the interior of the building and the house we live in, but the scenery outside the window has changed. Surrounded by blue sea water, it seems to be covered by a huge blue curtain, which has unspeakable mystery.

"The guide took me to the top floor of the building, where the roofs are all at sea level. Standing on the roof, I can see the high sky and boundless sea water in the distance. Interestingly, there are a large number of green plants on the top floor of submarine dwellings. The tour guide told me that it was to make oxygen. On the top floor, you can see an artificial island not far from the sea. There are fairyland-like parks, fitness squares and open-air theaters on the island ... here, people are just like living on land. In addition, people also transplanted forests to artificial islands.

"Then, I followed the guide into the sea view hall built on the seabed, which has a huge glass skylight and can enjoy the scenery of the seabed. Here, I find that there are few fish, only some corals, and many "bus submarines" carry people among corals, which is equivalent to our bus. There are many private boats, which are equivalent to our private cars ... "

Before Zhihuai's words were finished, the "little doctor" could not bear his temper. He suddenly interrupted the "gifted scholar": "People came from the sea, and now they are back in the sea. Living in the crystallization of human wisdom is really a happy thing. Let me solve the energy mystery of the underwater world for you.

"The earth time at seven forty. At this time, the ocean is dark, and you can vaguely see the soft energy-saving lamps flashing in the streets and alleys of underwater cities.

"In addition to submarines, the most functional transportation hub on the seabed is the cross-harbour tunnel. The vehicle runs silently in the tunnel, and only the lights confirm that it has been here. This underwater city is completely closed, surrounded by a huge sphere made of solid diamond glass, which can withstand extremely high pressure. You may ask, the city is completely closed, so where does the food and water that people depend on come from? How to solve the problem of breathing oxygen? Oxygen is separated from the carbon dioxide exhaled by residents living in cities, and pure distilled water is separated for people to drink. Using energy-saving lamps similar to sunlight at the top of the city, every plant planted in the city can grow healthily. The stems, leaves and roots of plants are rich in high-protein nutrition, which solves the source of human food. Residents only need to pay for transportation and growing food every month.

"As for the power problem, urban planners have also come up with corresponding countermeasures. People's domestic garbage and excrement can produce a lot of biogas, which can be used to supply the power of energy-saving lamps. There is also a port at both ends of the city: a water outlet and a water inlet. They are connected to the central pipeline, and seawater constantly enters and exits from two ports, driving a huge turbine to generate electricity. The daily water inflow and outflow of the port can reach 3 million tons, which plays an important role in the city's power supply. I believe that in the near future, this underwater city may also be rated as' Top Ten Environmental Protection Cities'!

"This city is also an underwater scientific research city. Numerous oceanographers have settled here and made great efforts to study the ocean. The famous sea-to-land power project was launched here, and 80% of the land's electricity was exported from here, which contributed to the underwater city!

"People take the ocean subway to work in undersea cities and go sightseeing in coastal cities, and their lives become colorful. The dream of the ocean is realized in human hands ... "

"Little doctor, you speak too well! We seem to be sitting in the ocean subway! "

"Governing Huaihe River and Qin Pei, you two have shown us the bright future of the future ocean, which is really desirable."

"To realize your dream, you must rely on the efforts of generations of scientists. Otherwise, this is an unreachable dream. "

"I wonder if there are any builders of underwater cities sitting here."

"impossible!"

"Who said impossible? Knowledge is power and knowledge can change everything. Nothing is difficult in the world, as long as you are willing to climb! "

I don't know who said it, but the tone is quite firm. The students applauded his belief warmly. ...

2 13 1 year …

"Snapping" pulled me back from my dream. I rubbed my sleepy eyes and sat up. Oh, it's the naughty dolphin Yuanyuan calling me out of the window! It suddenly occurred to me that my parents and I just moved from a crowded city to this beautiful "Pearl of the Sea" city last week. The city is a sphere surrounded by a special transparent film, hence the name "Pearl of the Sea". Although this film looks transparent and soft, it is actually very tough. The violent erosion of the sea and the biting of the sharp teeth of the great white shark made it unbearable. City dwellers can reach out and play with crabs, soldiers and shrimps like a thin mist. People can also see a colorful underwater world through the film, with all kinds of grotesque fish, lined seahorses, octopus waving long limbs, and aquatic plants writhing with the current.

After breakfast, I said goodbye to my parents, and I set foot on the crystal channel leading to school. Speaking of this crystal channel, some universities still ask!

This is made of crystal glass tube, which is divided into three layers: electric racing track and walking track. Among them, the most widely used is the first-floor moving sidewalk, which is divided into four rows at the same time. The speed of the first, second, third and fourth rows is 50 km/h respectively. 30 km/h; 20 km/h; 10 km/h. It carries thousands of passengers like an assembly line. The second floor is an electric driveway, which is suitable for fans. On the third floor is a promenade, where you can often see some old people walking slowly with their pets; This three-layer crystal channel runs through the city, which is convenient and high-speed.

Five minutes later, I arrived in the city center, where there was a huge fountain like a five-story pagoda. It is not only beautiful, but more importantly, it is also an oxygen generator in the city. Next to the fountain is a station, or rather a "ball station". People only need to enter a sphere, and the sphere is controlled by a computer, so they can ascend to another underwater city or land. Every weekend, my mother takes me to grandma's home on this sphere.

Soon, the school arrived. This is a book-like building, symbolizing that we are swimming in the sea of books. Colorful flowers and plants surround the school, which is planted with fertilizer jelly. They are delicious! Also brought the pencil butterfly that Dr. A just introduced!

This is our "pearl under the sea". The reason why there is such an underwater city is that the population on the land is increasing day by day, crowded, and the environment is polluted. The area of the ocean far exceeds that of the land, and human beings have to rely on science and technology to return to nature! I thought: Since human science and technology can allow us to settle on the seabed, what will the Sky City and Mars Garden look like in a few years? We still need to explore and study, and I believe there will be another style.

Strange and wonderful marine cities are so desirable! In 2040, the city became a maritime city. Knowing that you are 20 10 today, let me be a tour guide and show you around the "ocean" in 20 120. I believe you will gain something. As we all know, the ocean accounts for seven tenths of the earth, and the marine pollution was very serious in 2009. 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.

The ocean of the future

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.

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.

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 era of simple 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 areas and undersea pastures 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 on the seabed 200 meters deep, with a four-story steel platform, about 70 meters away from the sea surface, 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.

The ocean of the future

The ocean is a cornucopia, containing many mineral deposits and high-protein foods. In addition, it has a vast space, covering an area of about 362 million square kilometers (140 million square miles), which can provide great living space for human beings. Therefore, many scientists are studying how to develop and use the ocean. I believe that in the future, the ocean will certainly make great contributions to mankind.

In the future ocean, many people have moved to Haiti. Why? Because of the rapid growth of the world population, the habitable area on land is getting less and less, and the environment on the seabed is very good, without noise and waste gas pollution. Who doesn't want to live under the sea? The population at the bottom of the sea has increased, so "underwater restaurants", "underwater schools" and "underwater playgrounds" have also been built. How happy people under the sea are!

The future ocean will provide many high-protein foods for human beings. Many people have seafood on their tables, such as "braised seahorse legs" and "sweet and sour hairy crabs" ... really nutritious!

The future ocean will provide human beings with resources such as oil, natural gas, coal, iron, copper, tin, manganese and sulfur. You see, the offshore oil platform has stood in the waves, the ocean research ship has sailed deep into the ocean, and the advanced seabed detector has dived into the deep sea, showing its great power.

The future ocean will bring endless and cheap electricity to mankind. Why? Because scientists use the movement of seawater and tides to generate electricity. In addition, it is also very effective to use seawater desalination to alleviate the water shortage in many arid areas on the earth.

The future ocean will bring endless benefits to people, but human beings should cherish and protect the ocean first.
