The earth is a beautiful blue planet. 71% of the surface of this planet is ocean, while the land area is only 29%. So can we live and use all the 29% of the land that humans live on?
Of course it is impossible. In fact, one third of 29% of the land area is still desert. After deserts are removed, there is not much land area available for human survival. With the continuous growth of the global population, we need more land to live and survive. Therefore, scientists continue to study and explore technologies and methods to turn deserts into oasis.
I believe my friends are no strangers to deserts. There are large and small deserts all over the world. The largest desert is the Sahara Desert, which is located in Africa and covers an area of 9 million square kilometers, which is almost the size of our country.
my country also has a large desert area. The largest desert in my country is the Taklimakan Desert, covering an area of 330,000 square kilometers, making it the tenth largest desert in the world. In addition, our country also has the Gurbantungut Desert (Junggar Basin Desert), Badain Jaran Desert, Tengger Desert, Kumtag Desert, Qaidam Basin Desert, Kubuqi Desert, Ulan Larger deserts such as Buhe Desert.
In the eyes of many people, the desert is a world of sand, covered with sand everywhere. But in fact, not all deserts are made of sand. Some deserts are mainly rocky, and there are many types of deserts. The most terrifying type of desert is quicksand deserts. For example, the Sahara Desert in my country is the world’s largest desert. The second largest mobile desert.
The desert is known as the forbidden zone of life. Although there is life in it, entering the desert is a very risky behavior for humans. If you are not careful, you can stay in the desert forever. Everyone understands the terrible and cruel nature of the desert, but there are still many people entering the desert every year.
Part of these people entering the desert is purely for curiosity, wanting to see what kind of scenery the desert is like. Others are treasure hunters. In our eyes, the desert is full of desolate deserts, but there are endless wealth and treasures hidden.
Every year, many explorers enter the desert to collect gold. There are many examples of getting rich through the desert, especially in western countries, there are many people who enter the desert to buy treasure. Everything in the desert is covered by sand, so someone asked the question: What would happen if all the sand in the desert was hollowed out?
I believe that many people are full of curiosity about the world under the desert, so what will there be under the desert? Some people may say that the earth is a rocky planet, and there are naturally rocks beneath the surface. The desert is continuously formed by the weathering of stones, so naturally there are some rocks and stones under the sand. There is no curious and spectacular sight. Is this really the case?
If you think so simply that there are some rocks under the sand, you are quite wrong. In fact, as long as we hollow out the sand, you will see a spectacular sand bottom world. The conditions for forming a desert are actually not complicated. In arid areas with little rainfall, plants continue to die because it does not rain all the year round. Without the windbreak and sand fixation of plants, stones will continue to be broken down into small particles by the wind.
The small particles are constantly insights by the wind to form smaller sands. These small sands are blown by the natural wind and gathered together to form a desert. The prerequisite for the formation of a desert is the lack of water, followed by the continuous erosion of natural wind, and this process is very long, not decades, hundreds of years can be formed.
It takes more than tens of thousands of years for any large-scale desert to form. For example, the largest Sahara desert in the world, it was once an oasis, and the African Homo sapiens lived here. Later, the environment changed. Rainfall was reduced, coupled with the reduction of vegetation caused by Homo sapiens grazing. Natural wind took advantage of the vacancy and continued to transform the oasis into a desert. This time took tens of thousands of years.
Every desert has existed for at least thousands of years, and some have even reached hundreds of thousands of years. In such a long time, the desert did not live without any life. In addition to some animals living in the desert, humans in ancient times also lived in the desert and established a kingdom.
In the world’s famous deserts, there were some ancient countries thousands of years ago. In fact, many deserts thousands of years ago were not as bad as they are now, and they still allow many people to survive. It was only later that with the continuous advancement of desertification, the soil for survival was lost, and these desert kingdoms were eventually buried in the depths of the desert.
It can be seen that there are many relics of human civilization that we have forgotten and disappeared in the desert. Because desert archeology is more difficult, the relics of the ancient desert countries we found may only be part of them, and more of them are buried under the desert.
If all the sand is hollowed out, then the relics of the ancient desert country that have disappeared for thousands of years will reappear before our eyes. What a huge human wealth. Many treasure hunters enter the desert, a large part of the reason is to find the relics of the ancient country that exist in these legends.
In addition to these ancient relics, what else will be under the desert? That may be a large number of bones of various creatures. If it is a desert that has existed for more than tens of thousands of years, then the scale of biological relics in the sand-bottom world will be larger, and the desert itself is a natural biological protection site due to lack of water and a dry climate.
If a creature stays in the desert, even if thousands of years or tens of thousands of years have passed, it will be able to leave a better side of itself on the sandy bottom, or form a better biological fossil. In addition to these, the desert also has a variety of rich minerals, as well as a large amount of oil and natural gas.
Although there are many resources in the desert, especially oil, because of the desert environment, human beings want to exploit the resources in the desert and need to pay more. Therefore, the current desert has not been really used, and for many people, more hope is to be able to transform the desert into an oasis, so that humans have more land to live and survive.
It is very difficult for a desert to become an oasis. Plants need water to survive, but deserts are very short of water. Some deserts have not even had a drop of rain for decades. With current human technology, there is only one way to drain the desert, and that is to introduce freshwater from other places into the desert artificially. For example, it was once proposed to introduce the water from the Yangtze River into the Taklimakan Desert.
Such a method seems feasible, but it is also very difficult to implement. Not to mention the huge bonuses that the project needs to invest, even if the entire Yangtze River water is introduced into the desert, it will not have much effect. What’s more, the Yangtze River is related to the drinking of a large number of people in our country, and it is impossible to let it drain into the desert.
The real hope is that the way to turn the desert into an oasis is a climatic weapon. Only the abundant rainfall of nature can change the desert. Natural rainfall in the desert environment is very difficult. Only when human science and technology are advanced and tools such as climate weapons are available, we can control the weather and give artificial rainfall to the desert.
In any case, the continuous expansion of the desert area is not a good thing for the ecology of the earth and mankind. It is inevitable to transform the desert in the future. As long as our technology can artificially change the weather, the solution of the desert problem will not be difficult. Perhaps in the near future, the earth’s deserts will become history, and humans will also have a large amount of land area.
