Preface.
71% of the earth's surface area is covered by oceans, and the depths of the oceans can reach depths of up to 11,000 meters, which is a field full of mysteries and unknowns for mankind.
In this vast and mysterious sea, humans have discovered something that should not exist, what is it?
1. The process of human exploration of the ocean.
Ever since humans had a curiosity about nature, they began to explore the oceans.
At first, it was to find food, or to escape natural disasters and shipwrecks, but slowly, human beings learned more and more about the ocean.
In ancient Greece, people began to use wood, sheepskin and other materials to try to make boats and go on ocean expeditions, which was also the beginning of oceanography.
By the end of the 18th century, when people had a better understanding of geography and the natural sciences, oceanography began to flourish, nautical science made great progress, and ocean observation technology became more advanced.
At the end of the 19th century, the advent of submarines provided an incomparably important means and guarantee for human exploration of the ocean. Because submarines can move underwater for a long time and are not affected by walruses, they have gradually become the right-hand man of marine scientists and have made great achievements in marine science research. Scientists have made many deep dives using submarines, successfully climbed many of the "highest peaks" of the ocean, and even found many strange creatures and landscapes in the world's deepest Mariana Trench, which also makes people understand the ocean more deeply.
In this mysterious and secret sea, in addition to sea creatures, humans have discovered some things that should not appear here, why is this?
Are these objects all ** from?
II. Threats in the oceans.
While there is a strong interest in the ocean, it also presents great dangers and threats as well as the convenience it provides to humans.
If you look at the huge shipwrecks in history, you don't know how many lives have been taken, and you can see what kind of dangers are hidden in the ocean, and this is only part of the natural disasters.
In addition, the ocean also contains huge biological threats, such as sharks, octopuses, etc., these ferocious sea creatures often attack humans, adding great difficulty to human exploration.
Even those seemingly docile sea creatures can become extremely aggressive when they feel threatened or displeased, posing great danger to humans.
What's even more terrifying is that there are all kinds of poisonous marine life in the ocean, and once you come into contact with these poisonous creatures, it is likely to cause human poisoning and death.
Seawater itself is also very dangerous, people often say that alkaline salt water can be *** This is because seawater is similar to human blood, if exposed to seawater for a long time, the human body will lose the regulation of body temperature, and then affect the normal function of the body, and even lead to death.
And that's not just the shallow sea, but once you go deep into the seabed, you'll face other more dangerous challenges, such as pressure, temperature, etc., which are very dangerous.
In addition, there are some special environments in the ocean that humans cannot survive, such as the dark areas of the seabed, which are very dim due to the lack of light, and humans can hardly see the surrounding environment, let alone carry out exploration.
The pressure in the sea is also extremely high, and there are often strong currents here, which pose a great threat to human life and safety, which is why the ocean is always full of mystery and attracts human beings to continue to explore.
Whether it is from the shallow sea area or the deep sea area, the ocean is a challenging and dangerous area for human beings, but human beings have relied on their courage and wisdom to continue to explore and find many mysteries of the ocean.
3. At a depth of 10,000 meters, scientists have discovered things that should not appear.
In this sea full of mystery and danger, human beings finally succeeded in raising the diving depth record to 10,911 meters in the early 90s of the 20th century, that is, the first successful dive to the bottom of the sea at a depth of 10,000 meters for the first time in human history, which is also the first time in nearly a century that human beings have reached the deepest area of the seabed, but when scientists saw the scene here, they were very shocked, because they found something that should not appear.
According to scientists' speculation, this mysterious sea area should be full of mythical existences, such as primitive sea creatures such as jellyfish, sea anemones, sea anemones, sponges, etc., but when humans first came here, they found that the vitality of the entire area was very weak.
Here, there is not even any marine life that can adapt to the environment, and humans have not even seen animal droppings, but this area is very clean, completely free of human waste and pollutants, which shocked the scientists, and they did not understand why such a place would be completely lifeless.
What shocked scientists even more was that there were even human objects in the Mariana Trench, such as steel waste, plastic bags, milk cartons, etc., which were all products made by humans, and they obviously belonged to land, but they didn't know how they appeared here.
Who dumps this garbage into the sea?
Or is there some special force in the depths of these oceans that can "swallow" these things?
These questions have left scientists pondering and studying.
In addition to these plastic wastes, scientists have also found some very mysterious substances here, that is, some rare metals in plastic waste and metal waste, these metals are very precious in human society, but these mysterious substances appear in the Mariana Trench.
Scientists have conducted a lot of research and analysis on this, and finally came to the conclusion that these metallic substances are produced by chemical reactions after humans throw objects into the ocean, and these reactions may also contaminate marine organisms, which makes the problem of marine pollution more serious.
With the continuous development of science and technology, mankind's exploration of the ocean is also moving forward, and it is believed that in the near future, mankind will finally be able to unveil the veil of this sea containing countless mysteries and discover more amazing mysteries.
The author thinks. Although the ocean is dangerous and full of unknowns, human exploration of the ocean has never stopped, and I believe that with the continuous progress of technology, human beings will eventually find some ways to solve the problem of marine pollution.
