There are many factors that cause the population growth rate. The first reason is the increase in life expectancy.

In areas with a better medical environment, the average life expectancy has reached 160 years. Pay attention to the average life span of a person, some of them are well maintained, and even live to 238 years old!

With such a high life expectancy, who wants to stay with a partner for a lifetime?

The human environment of the entire civilization is slowly changing because of the increase in lifespan.

After all, human beings are creatures who like the new and dislike the old. In the past, "accompanying each other for a lifetime" lasted for fifty or sixty years, but now they spend a lifetime of being together for one hundred and fifty to sixty years!

Human beings will remain in the state of young and middle-aged for a long time. Most people would rather have enough fun first, rather than start a family and have children...

As a result, the marriage rate is low and the birth rate is naturally reduced.

The second is the cost of training talents. The cutting-edge space industry has higher and higher requirements for the quality of the population. But in just a few hundred years, human intelligence will not advance by leaps and bounds.

Cultivating a high-quality talent may consume most of a family's savings.

Therefore, for most families, one child is enough.

"Many young people don't like to get married, and they don't even like to have children. Keeping DINK can actually improve the quality of life to a great extent. For these young people, it is difficult enough to support themselves. How can we consider the entire national security?"

"On the contrary, some poor countries have a higher birth rate... Even if distance online education is popularized, under the influence of a certain environment, the probability of high-quality talents being able to emerge is still low."

Looking at this report, Zhang Yuan was a little worried.

The aging trap, an exceptionally dire crisis.

The more old people there are, the heavier the social burden on young people will be.

The heavier the burden on young people and the worse their economic conditions, the less willing they are to have children.

It's a vicious circle, and it's very difficult to break out of it. Even if the government introduces various policies to encourage births, it often does not achieve very good results...

History has proved that the best way to cure aging is - war!

That's right, the reshuffling brought about by war can bring about the peak of fertility. This view has been proved many times by history.

But the current trend of the whole world is peaceful development, and it is impossible to have a war.

Moreover, as a normal person, Zhang Yuan does not want to use the world war to solve the problem of aging, which is simply putting the cart before the horse.

He shook his head, put these wild thoughts behind him, and continued to analyze the data.

[Under the influence of this trend of thought, the population of Bang Country has dropped from the original 51 million to 15 million, and it will be the first country that will self-destruct due to aging. 】

"Oh, man, the pill!" John, who looked on sentimentally, began to sigh again.

"Increased life expectancy has become the best contraceptive pill. There are more and more garbage people in poor countries, and they generally live on relief from rich countries. I really don't know what use these people are."

When discussing disputes, Zhang Yuan is not very good at it. He bit the bullet and retorted: "At least poor countries are also places where raw materials are produced, and they still have a little effect. If there is no poverty, how can there be wealth? As long as it is productivity, it is even lower. , how could it be useless!"

"In your eyes, everything is a pill anyway."

John was stunned for a moment: "Indeed, the development of earth civilization requires low-end population... It is impossible for all of them to be high-quality population. The distribution of population, no matter what era it is, must be pyramid-shaped."

Zhang Yuan shook his head: "Actually, on the whole, the civilization of the earth is still moving forward, isn't it? As for the population problem, I believe it can still be solved. Every era has problems in every era, and it is impossible to go smoothly."

"Anyway, I don't really believe that human beings will really perish because of problems like aging."

John replied: "Zhang Yuan, you are too optimistic. So far, human beings have used greedy strategies. When a problem arises, they will find a way to solve it instead of preventing it before it happens."

"This kind of decision-making system itself is unscientific, and there is a high probability that it will fall into the trap of mediocrity. Aging is already a big problem."

Zhang Yuan actually knew this too, but he still had a natural sense of expectation towards his mother civilization.

In this case, he also didn't want to debate too much with John, just keep reading the report below.

In response to a series of problems caused by the stop of population growth, government departments are continuously encouraging births and introducing related policies.

This kind of population policy has not been worked on for decades, and basically it will not have much effect, so he skipped the development of the middle thirty years and turned to the latest report.

When he saw the first few lines, his spirit was shaken.

"Hello, colleagues of the Earth Times! I am the new president of the Deep Space Foundation, Yuan Yuchan, and I will bring you the latest information on Earth civilization."

The new president of the foundation has become a middle-aged woman, but that's okay.

"In recent years, the best scientific and technological achievements have appeared in biology, mainly the deciphering of protein language, and the emergence of artificial womb technology!"

"...The deciphering of the protein language has brought about a qualitative change in life science!"

"We have tackled a large number of diseases, including the 'king of cancer' pancreatic cancer and various malignancies..."

"Overcoming the drug resistance of superbugs is no longer a luxury!"

Great news!

Seeing this, Zhang Yuan couldn't help but smiled in his seat.

Below is a large number of papers on protein language, involving all aspects of biology.

However, Zhang Yuan didn't know much about biology, so he couldn't comment.

He only knows that the work of deciphering the protein language must be extremely important. Human beings can gain a deep understanding of the essence of life from the most microscopic level.

To give a simple example, in terms of the immune system, HIV has turned from evil to good, which can help treat immunodeficiency. Some people with congenital immunodeficiency can now be cured. This kind of medical treatment can only be said to be a fantasy in the past!

"The average life expectancy is going to increase again. I don't know if it will affect the marriage rate." Zhang Yuan asked with great interest: "Have our biologists studied these new drugs?"

"It's being researched." John turned his head and said, "Our current equipment is too poor, and we can't make such a life-enhancing drug for the time being... In the next big year, there will be a conference on life sciences, but it won't be the turn of the two of us." Participate. We're not biologists."

"Okay." Zhang Yuan shook his head. Anyway, he is still young, so he doesn't need to think too much about life expectancy.

The issue of life and death, if you think too much, you just worry out of thin air.
