To be precise, the earth has experienced 17 small-scale extinction events so far, such as the Carboniferous rainforest collapse, Olson extinction, Kanian flood, Paleocene Eocene extreme heat events and so on.
In addition, the earth has experienced four medium-scale extinction events, namely, the end of Ordovician, the end of Devonian, the end of Triassic and the end of Cretaceous.
The most noteworthy thing is that the only "mass extinction event" in the history of the earth, that is, the "mass extinction event at the end of Permian", led to the extinction of more than 90% of the creatures on the earth.
Late Permian mass extinction event
The earth is dead.

Unfortunately, one day in the future, because of the destruction of the environment, or because of war, mankind will eventually come to the end of the world. Thus, an American university professor predicted the scene of the earth after the disappearance of human beings in the form of pictures.
The day after human death
Because the continuous pumping system was unattended, the subway in the city began to be flooded.
Seven days after the demise of mankind
Then the water cooling system of the nuclear reactor began to fail, and the high temperature caused a fire and destroyed the nuclear power plant.
1 year later, urban streets around the world were torn by the freezing and thawing force of water and then occupied by weeds. Two years later, some tree roots along the street grew upward and protruded from the ground, while others continued to grow downward, destroying the sewer system.
Four years after the demise of mankind
The unattended dead branches and leaves in the city may be struck by lightning and cause a fire. Human buildings began to collapse.
Twenty years after the demise of mankind
The sewer system was destroyed and the city was flooded. The roof of the house slowly collapses, and some buildings take hundreds of years to completely collapse.
500 years after the demise of mankind
The city is covered with forests. It will take 5000 years for the shell of nuclear warhead left by human beings to be corroded, and radioactive plutonium 239 will further pollute the environment. More than 65,438+500,000 years later, the earth began to welcome a new ice age.
35,000 years after the extinction of mankind
The metallic lead in the soil finally disappeared completely. It takes 654.38 million+years for the concentration of carbon dioxide in the atmosphere to drop to the level of agricultural age. After 654.38+10 million years, the remains of the human era, such as bronze sculptures, can still be seen on the earth.
After human death 1 100 million years
The sun has evolved into a red giant and the earth is extremely hot, but there are still new species that can survive.
Five billion years after the demise of mankind
The sun became a red giant, and its expanding volume swallowed up the earth.
After human extinction 10 billion years,
Television broadcast signals of the human era are still floating in the universe.
Four people in the world who will never die.
Many people want to live forever, but it is an irresistible law for human beings to live, die and die. But after some strangers, their life expectancy far exceeds that of ordinary people. Of the four immortal people in the world, Peng Zu lived only 800 years. He could have lived forever, but he may have committed suicide because he couldn't stand the long life.
First of all, the Jade Emperor
In all kinds of myths and legends, you can see the jade emperor. He is the highest-ranking immortal in the sky and can live forever. Of the four people who will never die in the world, he has a long life. It is said that he is the child of King Tinker Bell and Queen Moonlight. He has a long life and has received human incense. As long as the incense is not extinguished, he will not die.
Second, Jesus
Jesus, the founder of Christianity, is said to be the son of God and has the ability to live forever. After he came to earth, people crucified him because they didn't believe that he was the son of God. Unexpectedly, he came back to life three days later. Because he is the son of God, he has great power to pull people back from the edge of darkness and sin.
Third, Dracula
As we all know, vampires live a very long life, and Dracula is the ancestor of vampires and has an immortal body. It is said that he was originally a nobleman who believed in God, because his wife was framed by pagans and was tainted with the devil's breath. He accepted the temptation of the devil in grief and was called the ancestor of vampires.
Fourth, Peng Zu.
Peng Zu lived for 800 years in history. Why do you say he will never die? It is said that his name has long been crossed out of the book of life and death, and he can live forever. But maybe he found it boring to live alone, and then he killed himself after living for 800 years. After all, not everyone wants to live forever. After living for a long time, it is actually a very uncomfortable thing to watch someone close to you die.
Many people long for immortality, hoping that they can live longer and live forever. Anyone who has seen Journey to the West knows how crazy it is that many monsters live forever. These four people who will never die can be said to be very enviable, with a long life that humans can't even think about.
The earth after 700 billion years.
According to common sense, after 7 billion years, the earth will no longer exist. The supernova explosion of the sun will destroy almost all celestial bodies in the whole solar system, and the earth in the inner ring of the solar system can't escape at all. The existence of human beings is uncertain, but most of them are extinct. It is possible for human beings to immigrate to other planets in the solar system or galaxies within a certain distance with the help of science and technology and some natural forces, but it is almost impossible to exceed the speed of light. Life on earth is far less than 7 billion years old, while human beings are only a few million years old. The evolution of human gene toolset has fallen into a slowdown and stagnation. According to human's own strength, it is remarkable to exist for 100 million years.
Earth 1 year.
There is no living thing.
There is no living thing. The reasons are as follows: first, at that time, the earth was just formed, and there was spewing magma everywhere. Without liquid water, life could not survive in this environment.
Second, there were no organic substances such as amino acids and bases on the earth at that time. Even with these, in this environment, it is impossible to form the basic substances that make up life, and it is impossible to form life.
