Will humanity become extinct? Under what circumstances and in what way will it become extinct?

There are several reasonable possibilities: 1. The increasing severity of pollution and the possible nuclear leakage will lead to a large number of human poisoning deaths, resulting in extinction. 2. Due to global warming, the north and south ice sheets have melted a large number of glaciers when they reach more than 0°C, resulting in global submersion in the ocean.

10. A "superbug" implanted with many bacterial resistance genes was developed and inadvertently spread to the population.

Will humanity become extinct? If so, what could be the cause of extinction? Under the rapid development of human beings, the natural ecological environment on the earth has been seriously destroyed, and the earth's environment has become more and more impoverished.

One day human beings will become extinct, time has proved that nothing is eternal, people may have a day of national destruction, and in what way people will perish, this can only be combined with the current stage of scientific and technological knowledge, bold attempts to guess. If people can go far enough, then the most worrying thing is the disaster of falling from the sky. For example, planets or comets hit the Earth,** long hidden gamma-ray bursts in space, and solar eruptions of super flares.

Longer things are not taken into account, such as the Sun becoming a red giant in 5 billion light-years, and the collision of the Solar System and the Andromeda Galaxy more than 3 billion years later.

the outbreak of nuclear war; If a war breaks out in the nuclear-armed countries of the earth and nuclear warheads are used, nuclear warheads will cause the death of some people, and the radiation sources and dust caused by nuclear warheads will also change the environment, which will lead to the extinction of mankind. Meteorites hit the Earth; If an asteroid of more than 10 kilometers hits the earth, then the earth may be destroyed, and before the level of star navigation is grasped, human beings will be destroyed along with the earth. Discovered by aliens far beyond humans; If you are accidentally seen by alien creatures, and it is unfriendly to alien creatures, then people are also at risk of destruction, because the alien high-tech with the level of star evaluation and sailing will definitely be much higher than people, and it is easy to destroy human beings.

Earth's internal activities; Hazards from other stars, or the earth's own reasons, the earth's inner core erupts, resulting in ** disasters, tsunamis, active volcanoes, these disasters are highly concurrent, destroying every population on the earth; Natural disasters can be floods, ** disasters, storms, super viruses, melting glaciers, dramatic changes in climate, meteorite impacts, any one or more combinations of which can lead to the extinction of humanity. Human sensitivity is like a touch of dust, and the rise and fall of a culture is not as good as the appearance of dust in the universe. The second type of calamities, such as warfare and various physical and experimental operations, are of few types but extremely harmful.

The war directly harms lives, needless to say, some of the best equipment on the earth today is enough to destroy the people on the ground countless times. Junior high school physics experiments may cause world-class disasters, such as the devouring of man-made super black holes, and the development of physics is good, but once it is not controlled, it will become a disaster! Experimental operations are a very harmful one, and we must always be vigilant about this.

Humans will not become extinct, and if they do, the reason for extinction may be because there is no suitable environment for human beings to live.

I think humanity will go extinct, maybe in a few hundred million years! The main reason may be caused by environmental pollution.

There is a possibility that humanity will become extinct. In addition to supervolcanoes, there are also epidemics of epidemics.
