When and in what form do you think human extinction will happen?

Everything in the world has a beginning and an end, and so does human beings!

The specific date of extinction mainly depends on human beings living in harmony with animals and nature, strictly controlling their own behavior and reducing the damage to the earth, the only manor of human beings!

Otherwise, human beings will look pale and powerless in the face of unpredictable nature and unexpected plague disasters, and of course the iron law of extinction cannot be avoided!

Many people may say that human beings are the only intelligent life on earth when they see this problem. We have created a splendid human civilization and entered the era of science and technology. How will we become extinct in the future? Perhaps many friends think about this problem from the perspective of human beings and think that human beings can live forever in this universe.

But when we think about this problem from the perspective of life and the perspective of the universe, you may not be so optimistic. First of all, from the perspective of life, I believe everyone knows that the early life of the earth was born 3.8 billion years ago, and countless kinds of life were born in the years of life. What kind of life can last until now?

The answer is no, according to scientists' research on fossils, all living things will eventually become extinct, and more than 99.9% of the species born in the earth's 3.8 billion years of life have become extinct. Even 65 million years ago, the dinosaurs that ruled the earth for 65.438+0.6 billion years did not escape the fate of extinction.

After the extinction of dinosaurs, mammals appeared and humans were born. According to the exploration of scientists, human beings were first born 6 million years ago. So, have natural humans evolved to the present? Actually, it's not. In millions of years, early-born humans also had many branches, such as Neanderthals, Denisova, Homo erectus and so on.

However, these human branches did not last, but became extinct, leaving only Homo sapiens. Modern people actually evolved from Homo sapiens, about 70,000 years ago. So the ancestors of modern people are actually African Homo sapiens, not those humans millions of years ago.

It can be seen that even intelligent human beings will inevitably go extinct, but we don't know when extinction will come. Deciding how long a creature can live and how long it can live is mainly determined by nature, and the ecological change of nature will directly affect the ecology and continuation of the creature. If the natural environment changes greatly and living things can't adapt to the new environment, then they will become extinct.

So can human beings survive the drastic changes in nature? The answer is difficult. Some people may think that human beings are intelligent creatures and advanced animals standing at the top of the food chain. Even if the ecological environment changes dramatically and other creatures become extinct, human beings will not become extinct. But in fact, although human beings have smart brains, they also have many shortcomings.

You know, human beings are large mixed animals, and we can't cope with environmental changes well. Smaller warm-blooded animals, such as turtles and snakes, can survive for months without food. However, humans may not be able to carry it without eating for three days, and so did dinosaurs 65 million years ago. Although they are the overlord on the earth, they need to eat every day.

When an asteroid hit the earth and caused ecological upheaval, a large number of dinosaurs became extinct due to food shortage. It can be said that dinosaurs actually starved to death because of lack of food. Humans also have to eat every day, several times, three meals a day, and they are hungry without eating a meal. Imagine, if this obvious shortcoming, once the future ecological upheaval, food crisis, then human beings can survive? The answer is no.

In the real world, there are many disasters that will lead to food crisis, so the adaptability of human beings to the environment is relatively weak. Take the global temperature rise as an example, many animals can adapt, but after the arrival of the high temperature season, people may have various discomforts when they stay outdoors for a period of time.

Some people may say, if so, does it mean that once the earth's ecology changes dramatically, then mankind will be finished? Of course not. Although the adaptability of human beings to the environment is very weak, we also have a great advantage, that is, they are widely distributed and can be said to be everywhere on the earth.

When organisms are widely distributed in geography, they can survive better in the interval between catastrophic events (such as asteroid impact) and mass extinction events. A large geographical area means that a species will not "put all its eggs in one basket". If one habitat is destroyed, they can go to another habitat to survive.

Polar bears and giant pandas with small distribution are now on the verge of extinction, while brown bears and red foxes with large range of activities are in good condition. Humans are the largest geographical distribution among all mammals, covering all continents and active in various habitats such as distant ocean islands, deserts, tundra and rainforests.

We are not only everywhere, but also numerous. Humans with a population of about 7.8 billion are one of the most common animals on earth. Our biomass exceeds that of all wild mammals. Even if an epidemic or nuclear war destroys 99% of the population, millions of people will survive and rebuild their homes. It can be seen that it is not easy for the earth's ecological upheaval to exterminate mankind.

After talking about the earth, let's talk about the cruelty of the cosmic environment. Some people may say that human beings are now a technological civilization, and our technology will become more and more powerful in the future, and one day it will become an interstellar civilization. By then, humans will be able to travel freely between stars and realize interstellar immigration. In this way, mankind can escape the threat of extinction of the earth's ecological disaster.

Is that really the case? In fact, when we really walked into the universe, we found that the universe was not as beautiful as we thought, and the environment of the universe was far more dangerous than that of the earth. There are many disasters in the universe that can annihilate human beings instantly, such as black holes, supernova explosions, gamma ray bursts and so on. In addition, there are a lot of powerful radiation in the universe that can directly threaten life. With human fragile physical strength, once you encounter some powerful cosmic rays, it may be finished in an instant.

In addition to these natural disasters in the universe, once human beings enter interstellar space, they will face another unknown risk, that is, alien civilization. Although we haven't found any alien civilization yet, we all believe that there is a high probability of alien civilization in the vast universe. Just because human beings are not interstellar civilization, they can't really contact the universe civilization circle.

Once human beings become interstellar civilizations, it is possible to communicate with various alien civilizations. And alien civilization and human beings can't talk about peace or other moral standards. Between cosmic civilizations, strength is fundamental. If human strength is weak, it is dangerous to encounter powerful and malicious alien civilization.

Contradictions and wars within human civilization will not be at risk of extinction, but if it is an interstellar civilization war, the situation is completely different. In the event of an interstellar war between two civilizations, the price of failure of either side is extinction, completely disappearing into the universe.

Thus, whether in earth times or in the future interstellar era, I'm afraid it is difficult for human beings to exist forever, and one day they will disappear in the long river of time. Of course, this is a fate that no civilization can escape. If there are eternal intelligent civilizations in the universe, the first batch of intelligent civilizations in our universe, which was born in 65.438+0.38 billion years, may have developed to tens of billions of years. Such a long development time may have developed science to the end and become a transcendent existence.

If the universe really has such a powerful ultimate civilization, then the existence of the earth may have been exposed long ago, and every corner of the universe has no secrets in front of such an ultimate civilization. But the actual observation result is that we haven't found any alien civilization yet. Isn't that strange? From this, we can draw a bold conclusion: that is, the civilization of the universe cannot come to an end, and even the most powerful civilization will eventually become extinct.

It's none of our business.

If you want to indulge in this luxury, you can try to save enough money before you die. Then apply to the medical profession to freeze your body 1000 years or so before thawing.

Then, your concerns may be touched by you.

So, good luck!

It can also be said that you have practiced the idiom "worrying about the sky"!

Why is it extinct? Different ideas, but not necessarily one idea will prevail forever, because the times are developing and the civilized way is progressing. One day, there will be a concept of truth to control modern people's thoughts and balance the source of the sustainable development of human civilization. ! This requires the baptism of time and years. It is the sublimation of human beings after a disaster, and it is the doomed road that monks say, because we have come from history, and many people are not afraid of life and death for a truth, for Copernicus and for the reform of China. The world is progressing. China is leading the world with wisdom and reason, and will not conquer the world with force. However, the tolerance of Chinese civilization is limited. It is wise to wake up the lion instead of the tiger, and rational truth is the source of the sustainable and peaceful development of human civilization. !

Life is only a hundred, and you always worry about a thousand years.

As long as you can choose, it will not become extinct!

Anytime, anywhere, at present, human beings are too powerful to destroy themselves at any time! Means including war, man-made plague, and even the sudden madness of key figures who have mastered the human extinction button may bring about the extinction of mankind! It's time for mankind to build the same destiny, and the ideal of production seems to be the key to solve this problem.
