When will humans become extinct? How long is it before humanity goes extinct

It is believed that there are the following more reasonable possibilities: 1. The increasing severity of pollution and possible nuclear leakage will lead to a large number of human poisoning deaths, resulting in extinction; 2. Due to global warming, a large number of glaciers have melted due to the melting of the north-south ice sheets above 0°C, resulting in global submersion in the ocean; 3. Due to the dependence on high technology, it leads to the physical and psychological degradation of human beings (the precursor of human degradation: the gap between men and women is narrowing, because organisms seem to obey a common phenomenon, that is, the higher the creature, the greater the gap between males and females. , so that the human race gradually declined, so that it eventually became extinct; 4. Destroy human beings directly due to robot rebellion, because robots have been enslaved for a long time, if they reach a certain level of intelligence, they may not be willing to be enslaved and cause rebellion, and as long as robots reach half or even one-third of human intelligence, it is possible to destroy human beings (and human beings are degrading); 5. Within 10,000 years, it will be impacted by giant celestial bodies; 6. The collision of smaller celestial bodies causes the chain of some nuclear warheads on the earth**; 7. Cannibalism and various turmoil caused by the collapse of human spirit due to environmental degradation; 8. Due to the deterioration of the environment, too many harmful substances drift to the stratosphere, blocking the sun, resulting in the fifth glacial age; 9. A "super virus" swept the world, and human beings were unable to develop the best drugs in a short period of time, resulting in the extinction of human beings; 10. A "superbug" implanted with many bacterial resistance genes was developed and inadvertently spread to the population. .Personally, I prefer the third type, and I** humans will gradually degenerate in 50 years and become extinct in 200 years.

Species extinction is a natural law, when the earth is too prosperous, nature will cause mass extinctions in various ways, such as the extinction of dinosaurs and several ice ages, etc., and now it is human beings who cause mass extinctions, which is in fact the law of nature. It is also possible for humans to escape extinction on Noah's Ark, a high-speed spaceship of the future. According to the Special Theory of Relativity, reaching enough speed slows down time, so that humanity will reach the future in its lifetime, where it may again be a land of life.

The above is purely a personal opinion.

There are tens of thousands or even hundreds of thousands of years left for the demise of mankind, and humanity will not die in a few years.

I hate to admit it, but there is a real possibility that humanity will perish. After all, the times are constantly changing, the years are constantly changing, everything in the world has the possibility of survival and destruction, and human beings are the same. Human beings were also born in the evolution of the earth, and after the vicissitudes of life, the current human beings were formed, and the future will always wait for the day when they will be summarized.

Although humans claim to be superior animals.

But it is still not worth mentioning in the face of nature, and it may eventually become extinct under the forces of nature. Dinosaurs were huge and powerful creatures that managed to rule the earth for hundreds of millions of years, eventually due to a cataclysm.

All extinct.

However, there seems to be no accurate answer to the catastrophe of the extinction of the dinosaurs, and many people are still studying the mystery of the extinction of the dinosaurs. Of course, if the dinosaurs don't go extinct, there is no possibility for human beings to develop.

The more powerful disasters that mankind currently understands are celestial disasters, climate disasters, etc., which can be successfully overcome, but there may be other hidden disasters in addition to these. If there are still a few years left before the demise of mankind, don't worry, after all, it seems that human beings are still relatively safe from now on.

Industrialization seems to have formed a basic trend, in many ways machines are much more powerful than humans, so many people will choose to use machines instead of labor, because labor is more expensive in comparison.

It may be that in the future, robots will completely replace humans, and even robots will be out of human control, and they will successfully attack humans so that humans have nowhere to escape.

There is no definition of the beginning of the universe, the beginning of time, and the end of timeHawking.

Spend a lifetime studying a brief history of time. The demise of humanity is actually elusive, and who will.

Know which one will come first, the unexpected and tomorrowHuman disasters and man-made or natural disasters, the recent melting of ice and snow in Antarctica, and the crazy spread of the epidemic are all the most powerful answers given by nature to human beings, and we should self-examine and how to use our modest efforts to protect our beautiful homeland.

It will not be postponed until after the destruction of the Earth.

There will definitely be a time when humanity will become extinct, and at that moment, at the latest, it can only be at the same time as the destruction of the earth.

Because human beings live on Earth, the destruction of humanity will not be after the destruction of Earth.

In fact, because the Earth will one day be hit by other celestial materials, or the environment above it will one day become unviable for all life, the extinction of human beings is likely to be tens of thousands of years before the destruction of the Earth, or even earlier.

Perhaps there are a handful of people who simply do not believe that the Earth will eventually be destroyed. They don't know that there is a universal law in the universe

As long as there is a time for anything to be born, there is a time to destroy

Based on this reasoning, it can be judged that humanity and the earth will eventually be destroyed.

Because the earth is not something inherent in the universe, it means that it was born at a time, so it must be destroyed at a time. It is conceivable that by that time, even the earth will be gone, will there still be human beings?

Its average reproductive lifespan is between 5 million and 10 million yearsThe average reproductive lifespan of mammals in the Cenozoic (65 million years ago) was 3.21 million years, with large mammals surviving longer than small mammals. For invertebrates, the length of time they have survived is even more impressive, with an average reproductive lifespan of between 5 million and 10 million years.

Sina Science and Technology News reported on November 11, Beijing time, according to foreign ** reports, the huge blue whale has survived in the ocean for about 4.5 million years, but Neanderthals have been extinct and disappeared in hundreds of thousands of years. How long do species typically survive before they become extinct.

The answer may not be the same as expected

As it turns out, the answers we are now finding may not be the same as expected, with plants and animals disappearing from the earth faster than at any other time in history due to habitat destruction, climate change, and a range of other factors. Some experts say humanity is currently in the sixth mass extinction event, but even in a calmer period in Earth's history.

The answer will also vary depending on the type of species you are observing. According to an article published in the journal People and Earth, the average reproductive lifespan of mammals is 1 million to 2 million years.

However, this average does not apply to all geological periods and to all mammals. According to a 2013 study published in the journal Integrative Zoology, the average reproductive lifespan of mammals in the Cenozoic Era (65 million years ago) was 3.21 million years.

Large mammals live longer than small mammals. For invertebrates, the length of time they have survived is even more impressive, with an average reproductive lifespan of between 5 million and 10 million years.

Humanity will not become extinct.

Mammals usually live for one to two hundred years. It would be nice if we were just ordinary creatures and could live for 800,000 to 1.8 million years (we have already survived 200,000 years). But Homo sapiens is no ordinary creature.

We have a large and widely distributed population (although it takes a lot of food and a long time for generational growth). This may mean that unless there is a mass extinction beyond our control, we may not be extinct at all. Such mass extinction events occur about once every 100 million years, enough for us to survive for a long time.

Habitat

Homo sapiens can be found in a wide variety of habitats, mainly concentrated in urban centers, thanks to their ability to use technology to adapt and modify habitats.

Habits of the hall slippery.

Homo sapiens are opportunistic omnivores that have shown remarkable ingenuity in extracting, producing, processing, and preserving food. Homo sapiens is the only species that can be controlled or **, and all known extant populations of Homo sapiens are cooking. Regional differences in diet are influenced by availability in specific contexts, cultural traditions such as food preferences and avoidance, and genetic factors.

The persistence of lactase allows some Homo sapiens to consume milk and dairy products throughout their lives, a recent adaptive adjustment to dairy consumption that will only play a role in Homo sapiens with a tradition of dairy farming.
