"In 1925, the Kuomintang government ordered the Tarim River to be diverted, which resulted in the water sources in the lower reaches of the Tarim River drying up, countless homes being destroyed, cultivated land barren, land desertification developing rapidly, and Lop Nur desertification initially taking shape."
"In recent decades, the population on both sides of the Tarim River has surged, and the demand for water has also increased. The expanded cultivated land requires water, and water is needed to mine mineral deposits. Where does the water come from? People desperately ask for water from the Tarim River, and in the uncontrolled extraction
, the Tarim River was finally drained, causing more than 50,000 acres of land along its bank to be threatened by desertification."
"Lop Nur, which used to be beautiful and fertile in the past, was forced to take off its coat of earth and expose its bare chest because of the cutoff of its water source. After decades of painful and helpless struggle, it finally transformed from an oasis into a sea of sand."
Hearing this, everyone suddenly stopped laughing. The beautiful and rich oasis in the past has turned into the shocking and desolate desert in just a century. Such a strong contrast, and the culprit of all this is us humans. Such a huge tragedy
, so sad.
Professor Guo did not stop and continued: "With the desertification of Lop Nur, the disappearance of water sources and the shortage of food, most species have perished, including many rare species, and humans have lost many precious resources, which is very disappointing.
People deplore it.”
At this point, Professor Guo changed the subject and said: "But the wonders of nature's creations cannot be completely destroyed by humans. The pace of species evolution cannot be controlled by any human force. After the living conditions in Lop Nur were harsh, some species entered
Once you arrive here and settle down here, over time, this place will become a new oasis, a brand new underground world."
"Don't ask me when these species came in, and don't ask me how these species came in. I don't know either, but I know that the formation of this inner earth world is definitely related to us humans. It can also be said that,
This inner earth world was created by us humans."
"As for the conditions for biological survival, Lao Qi just said that sunlight, water and air are all necessary. There is an underground river here as a water source. It should not be a problem to support this underground world. Air is not a problem either. There are plants here.
There are animals and the oxygen expelled by plants is supplied to the animals, and the carbon dioxide exhaled by the animals is supplied to the plants, forming a good cycle."
"The only thing is that I haven't figured out photosynthesis yet. According to physics, these plants must first be exposed to light to produce photosynthesis, produce chlorophyll, and form color. But here is more than 10,000 meters underground, and there is no sunlight at all.
Maybe it shines in, how can photosynthesis occur without light?"
Hearing what he said, a few of us looked up in unison. It was better not to look. At this look, we couldn't help being startled. We saw a blue sun hanging directly above the river.
, emitting soft light blue light, the entire space is enveloped in its light.
Everyone was stunned. Everyone had seen the sun, but no one had seen the blue sun. At most, they had seen several solar eclipses. This time it was an eye-opener.
Professor Guo also noticed something was wrong with us. He followed our gaze and suddenly he was frozen there, with his mouth wide open. The expression on his face changed from surprise to joy, and finally turned to excitement, and his whole body started to tremble.
(That’s all for now, go out to walk the dog, come back and continue~!)
