The earth is the home of human beings, and it is also the only planet where human beings can explore the living planet at the current level of science and technology. Do you know? The demise of the earth is inevitable, this is not alarmist. Let's take a look at the possibility of human extinction on Earth.
Why is the destruction of the earth inevitable? At present, the earth is 4.55 billion years old, and 9.6 billion years is the life expectancy calculated by scientists, so what are the possibilities for the demise of human beings on the earth?

The first possible cause: the demise of satellites. This satellite refers to earth's natural satellite --- the moon. After the moon disappears, the Earth will lose the protection of the satellite and the meteorite will hit the Earth directly. The Moon also plays a key role in the virtuous circle of the Earth's interior, where the tides will cease to exist.
The second possible cause: the recent demise of yellow dwarfs. The first effect of the disappearance of the sun is that the temperature of the earth will plummet, the source of the earth's energy will no longer exist, and all living things will basically die.
The third possible cause: the disappearance of the atmosphere. The role of the atmosphere is crucial to the Earth's current ecological environment. Let's not say that the atmosphere has completely disappeared, and in previous years, the atmosphere has become thinner and more leaky due to ozone, and there have been corresponding effects. The temperature difference between day and night will also become very large, at least not within the range that humans can bear.
The fourth possible cause: the end of humanity itself. According to statistics, the total number of nuclear weapons now possessed by human beings can destroy the earth several times. The ultimate result of human war is 'zero', what concept, there is no difference between victory and defeat, everything is nothing.
The fifth possible cause: the disappearance of land. One of the sources of water on Earth is that the early Earth had rainfall that lasted for millions of years. If the amount of water is too large, the glacier melts and other factors, there will also be a possibility of the land becoming smaller and disappearing, so that human beings will no longer have a living terrestrial environment.
The fifth possible cause: black hole engulfment. The existence of black holes is still a mystery, perhaps just a vortex in the vast universe. It is as if the whirlpool in the sea is infinitely enlarged, forming a black hole. But this is only a hypothesis, but a black hole is a existence that cannot even escape light, and stars can be swallowed up, so there is also a possibility that the earth will be swallowed.
The sixth possible cause: the existence of higher organisms. The universe is immeasurable, then human beings are also aware of its very small and small range, then there may be more advanced creatures. Then, there are creatures that we can't detect them, they may detect us, or a possibility that we can distinguish things in three dimensions, if there are creatures that can distinguish between five-dimensional space or higher dimensional airborne...
The seventh possible cause: the division of the Earth itself. It is said that the Moon is also split off from the Earth. Then it shows that the earth still has the possibility of continuing to divide. If it is divided again, it means reorganization, and all life must be reorganized with it.
Cherish life, cherish the environment on which human beings live, cherish our homeland------- earth!
