As we all know, 71% of the earth’s area is ocean, and only 29% of the land area is desert. Therefore, the land available for human habitation on the earth is very small compared with the whole earth. One third of the land area has been swallowed up by desert. Many people think that if only the desert could be turned into an oasis, with more land area, the house price would not be as expensive as it is now.
Turning desert into oasis? It seems to be a very beautiful thing. Scientists are not unable to think of a way. Take China as an example, the largest desert is Taklimakan Desert. Located in the center of Tarim Basin in southern Xinjiang, it is the largest desert in China and the second largest desert in the world. The total area of desert is 330000 square kilometers. If only such a large area could become an oasis.
If you think about turning a desert into an oasis, the biggest problem is water supply. As long as there is enough water, it is possible to turn a desert into an oasis. With water, you can plant many plants, and the desert soil will be gradually improved and eventually become an oasis. But we know that there is little rainfall in the desert all the year round, and sometimes there is not a drop of rain for several years.
The Taklimakan Desert belongs to Xinjiang province. Due to the distance from the ocean, the ocean airflow can not reach Xinjiang. Therefore, the annual rainfall here is very rare and the climate is dry. This is the reason why the present Taklimakan desert is formed, and the area of desertification is increasing every year.
Then why is there little rainfall in Xinjiang? This is mainly related to its location. As we know, the rainy weather is that after the warm and humid air mass on the ocean is formed, it moves continuously to a certain area under the influence of the monsoon, and the rainy weather will come to which area. But there is a towering Himalaya in front of Xinjiang, which has become a very difficult natural barrier.
The Himalayas are the tallest and most magnificent mountains in the world. It stands on the southern edge of the Qinghai Tibet Plateau. It is distributed in Tibet, Pakistan, India, Nepal, Bhutan and other countries. When the warm and humid air mass in the Indian Ocean is formed and pushed northward under the southwest monsoon, the towering Himalayas become a natural barrier that is extremely difficult to cross. At this time, eager to move northward, the warm and humid air group was unwilling to swim around and finally found a gap, which was the tail of the Yarlung Zangbo River Grand Canyon. The warm and humid air swarmed into the Grand Canyon. Unfortunately, after entering the winding Grand Canyon, it gradually lost its invincible momentum. After the water vapor channel successfully created the oasis in Southeast Tibet, its stamina was slack, and it stopped before it reached the north of Tibet.
It is because the huge Himalayas block the front and the moisture mass can’t enter that the rainy weather in Xinjiang is rare all the year round. The rain in the desert is less, and the area of the desert is also expanding. So my friends with big brain holes come up with a coup: if you blow up a huge hole in the Himalayas, a lot of warm water will go north and rain in the Taklimakan Desert There will be more water and weather. With a lot of water, the desert will become an oasis. It will become the second largest granary in China. It will solve the food problem of hundreds of millions of people and provide more living space.
This idea sounds very exciting and beautiful, but it will be very difficult to put it into practice. It can be said that it is difficult to do it properly. There are several reasons. One reason is that even if we have the ability to dig a huge opening in the Himalayas, how to deal with the waste rock generated? These wastes are enough to make a new little Himalaya. Some people may say that it’s good to pour them into the sea and reclaim land from the sea. The idea is very good, but the capital required will be a huge number. I’m afraid China’s economy can’t support such a huge project.
The second reason is the barrier of the Qinghai Tibet Plateau. Even if we blow up a big gap in the Himalayas, warm water and air will flow in, but when we get to the high altitude areas of the Qinghai Tibet Plateau, glaciers will form because of the cold weather. At that time, we may see the formation of another small Arctic. Of course, some people will say that the global temperature is constantly rising, and the climate of the Qinghai Tibet Plateau is very cold The temperature is not as cold as before, and warm water will not be frozen when it comes in.
As a matter of fact, there are openings all over the Himalayas, such as Pulan, Zhangmu, Chentang, Yadong, etc. the warm and humid air from the sea will also go up to the plateau along these openings, but after climbing, its influence scope becomes very limited, forming a few oases. If we open another opening in the Himalayas, we will only have another oasis, which will not have much impact on the rainfall in the desert.
From this, we can see that it’s impossible to blow up a big gap in the Himalayas to draw warm air and try to turn the desert into an oasis. In order to turn the Taklimakan desert into an oasis, we need to develop real scientific and technological means in the future. Only science and technology can turn the desert into an oasis. So what kind of technology can do it? That’s the weather weapon.
As for meteorological weapons, scientists have been studying. In our cognition, nature is invincible. We have only passive defense against natural disasters such as typhoons, earthquakes and rainstorms every year, and we can’t take the initiative to influence change. But with weather weapons, it is different. It can change the weather and make it serve human beings, not bring disaster. With meteorological weapons, we can control the flow of warm air and drive it to places where rain is needed, such as deserts. In this way, deserts can drop a lot of rain and it will be easy to turn deserts into oases.
Of course, meteorological weapons are still in the stage of theoretical concept, which is far from real realization. However, it is believed that human beings can certainly study them in the future, and then the Taklimakan desert will become an oasis. Guys, what do you think?
