an end for demise

After the Jurassic-Period, the Victorian-Paleogene extinction event occurred about 65 million years ago, causing the extinction of dinosaurs and many other creatures. The Jurassic-Period also ended. It was widely believed that an asteroid with a diameter of about 10 kilometers hit the Earth as the main cause of the extinction. The shockwave generated by the asteroid's impact on Earth sent tens of thousands of tons of sulfuric acid gas into the atmosphere, which combined with the moisture in the clouds to form sulfuric acid rain, causing global fires. About one-third of the land was burned, plants were severely damaged, and large carnivorous dinosaurs that fed on plants also faced food shortage. At the same time, the impact could also trigger a series of disasters such as earthquakes and volcanic eruptions, causing the global environment to deteriorate rapidly. Dinosaurs and many other creatures could not adapt to this harsh environment and died in large numbers. Only about 10% of the creatures survived. This event marked the end of the Jurassic era, and the Earth's ecosystem underwent a huge transformation. Read Dragon Reincarnation, Revenge Begins at Five! cartoon

From a scientific point of view, there were some factors that would inevitably lead to the demise of the Earth, such as the cooling of the Earth's core, the death of the sun, the collision of galaxies, etc., but the timing of these events was difficult to determine accurately. The time for the Earth's core to cool down was unknown. The Earth's core was filled with radioactive materials, and the decay of these materials would cool the core. The Earth's magnetic field would disappear, and the Earth would lose the protection of the atmosphere like Mars and die. The death of the Sun would also cause the Earth to face extinction, but this process was still extremely long. Humans currently had about 2 billion years to leave the Milky Way, but this was not the exact countdown to the death of the Earth. It was just an approximate time range based on current knowledge. In addition, there was also a point of view that a man-made blackout caused by a shortage of resources in the early 22nd century might trigger a third war. Although this was a war that tested humanity and did not directly lead to the destruction of the Earth, it also hinted at the crisis that human society faced in the process of the possible destruction of the Earth.

The reason for the demise of the Ming Dynasty was controversial, but it was generally believed that the reasons for the demise of the Ming Dynasty were many, including politics, economy, military, culture, and many other aspects. Politically, the emperors in the middle and late Ming Dynasty lost their ability to govern the country, which led to political corruption, bureaucrat corruption, and the people's livelihood, which made the country's financial situation extremely difficult. The economic decline in the middle and late Ming Dynasty led to a decline in commodity prices, a decrease in agricultural harvests, and a difficult life for the people. In terms of military affairs, the border defense system in the middle and late Ming Dynasty was lax, and the combat effectiveness of the army decreased. The corruption of the army caused the army to be unable to defend the country. In terms of culture, the cultural traditions in the middle and late Ming Dynasty showed a trend of decline. For example, literature, art, philosophy and other fields were all influenced by Western ideas, causing Chinese culture to gradually lose its uniqueness. These factors together led to the demise of the Ming Dynasty.
