Now there is a question that puzzles a few people: Why did these rats commit suicide?

Why?

Wang Yang remembered a case very similar to modern times, the mystery of lemming suicide.

Lemmings also have a very good tradition of committing suicide. They live in cold areas in the north. In order to survive, their breeding numbers are very high.

A litter of more than a dozen or twenty is not a problem.

They are born and grow quickly. It only takes three or four years to reproduce into the millions, which is terrifying.

Why can they grow so fast? Are there no natural enemies?

Yes, but the number eaten by natural enemies is far less than the number they reproduce. If you give birth to twenty cubs and eat two, you will still have eighteen cubs alive.

The growth rate of these eighteen animals is very fast, and they will give birth again soon, and then they will regenerate and continue to give birth.

In the end, it became a rampant rat plague. The lemmings ate everything they could eat, including trees, grass, and even rocks.

It's a complete mess, with no life in sight.

Its natural enemies had no choice but to survive and had no living space, so they forced some of them away.

In this way, their number becomes even more terrifying. How many can be eaten by just those few circling eagles?

What's more, the big eagles also need to change their taste and eat other animals to get balanced nutrition.

What will you do when everything is eaten up? Kill each other? They don't have such a strong taste, so they probably haven't thought about it.

Because they don't have self-awareness, they don't think about it, if I kill that person, I will have something to eat.

They may think that that person is also me. I cannot eat me. It is possible that their "I" refers to their species.

This is a problem. What should we do if we have nothing to eat? What should we do if the ecological damage is completely eliminated?

Death! There is only one way to die, there can be no other way.

The question is, how to die?

There was a documentary filmed before, which said that the lemmings took the initiative to commit suicide and jumped off the cliff to die for the sake of the species. It was extremely tragic and awe-inspiring. The wind was blowing and the water was cold, and the strong men never came back.

Is this true? Would a group of guys with no self-awareness kill themselves for other rats?

Fake! That documentary is fake. The group of lemmings did not take the initiative to die, but were driven away for the completion of the documentary. This is how the famous lemming suicide lament came about.

Later, someone exposed this, which raised another question. If they didn't die on their own initiative, why did they die?

There is only one reason, migration.

Wang Yang patted Xiao Hong, who was so shocked that she stayed on the spot, and pulled her to the edge of the cliff. He pointed to the sea below: "Don't be excited, they can swim."

Xiao Hong looked down, and sure enough, on the water surface near the sea, there were all rats with their heads sticking out. They were rapidly expanding towards the sea just like they were on land. Looking at their posture, they wanted to occupy the ocean just like they occupied the land.

"It turns out it's not suicide..." Xiao Hong's eyes widened. She originally thought that these mice couldn't swim and would drown if they jumped down. However, after falling down, they swam happily.

"No, it's still suicide, but they are just like moths and don't know." Wang Yang shook his head.

"They can swim, so why should they commit suicide?" The three of them turned their heads again.

Wang Yang pointed into the distance: "Do you think they can swim to the other side, which is so far away that you can't see it?"

Can't swim... The three of them shook their heads. The sea is so vast. Want to swim to the other side? How long will it take?

Two months? Half a year? Two years? Ten years? In such a long time, how can you ensure that you will not be soaked in sea water? That you will not lose strength? You will not be hungry? Animals in the water will not attack?

There is no guarantee that as long as they hold this idea and think they can swim to the other side, they will definitely die and "suicide".

"Then aren't they all going to die?" Wang Yingying felt a little distressed as she looked at the rats that came one after another: "It would be nice if we committed suicide in batches. We can catch rats to eat every once in a while and we don't have to raise animals."

"..." I feel sorry for this.

"But why do they have this idea?" The three of them looked at Wang Yang again. This is a very important question. Since it is migration, why is it such a difficult migration method that is impossible to succeed at all?

However, Wang Yang said something surprising: "Because every time, a small number of them will succeed."

"This is impossible. Wouldn't they go into shock after being soaked in water for so long? How to solve the food problem?"

Wang Yang said: "I didn't say they will definitely swim to the other shore, unless the other shore is very close, but some of them will be confused by the waves in the sea. When they emerge again, they will actually be beaten back, thinking that this is the other shore.

, so I swam back and succeeded."

"You mean, they actually swam back? But they didn't know it and thought they succeeded?"

Wang Yang nodded: "Yes, those rats that survived thought they were successful. The next time they migrated again, they would lead other rats to jump into the sea, and they have had this habit ever since."

"So that's it." The three of them suddenly realized.

However, Wang Yang did not talk about another concept, which is that every life, if it reaches a certain level, will commit suicide. It is about the subconscious mind controlled by the brain, and it is about genes.

Wang Yang felt that these had not been confirmed yet, so saying that it would cause trouble could not be considered true.

In his opinion, there is still a question of self-awareness or intelligence, which is the most important thing.

For example, everyone knows about Chinese history, but one thing is often ignored in books, something that no one pays attention to.

And this thing is actually another aspect of historical truth.

Before the pre-Qin Dynasty, the food produced in China was only enough to feed 10 million people, and it would not be enough to feed one more person.

Therefore, during the Spring and Autumn Period, there was a saying that there were no just wars in the Spring and Autumn Period. Why? Because there were too many people, and the only land that could produce food was so much food.

Why is there not enough land? Is it because there is not enough cultivation? No.

At that time, the land was not planted in ditches as it is now, but on ridges, which were similar to small hills. You could not plant in ditches. If you planted in ditches, if it rained, the seeds would be drowned.

Moreover, the land needs to be cultivated. If you plant it this year, you can get 100 jins of grain, but next year you will only get 50 jins of grain.

So there are too many people and not enough food. What should we do? Jump into the sea and commit suicide collectively? No, human beings with self-awareness can do it very simply: kill!

If there are many people, just kill them. Isn’t that enough to eat?

In the Warring States Period, Qin's general Bai Qi, why did he kill 400,000 people from Zhao? Because Bai Qi was cruel? No, he really couldn't do it without killing.

If I don't kill you all, how can we have enough food? If we occupy your territory, there won't be enough food, so we can only kill people! It's better to kill people from other countries than to kill people from your own country, right?

From a humanitarian perspective, it should indeed be criticized. After all, so many people were killed. But the question is, in that general environment, if we don’t kill people, what else can we do?

When the Qin State unified the six countries, it had iron tools and the production efficiency was a little higher. It could feed 20 million people, and one more person would starve.

And it should be noted that there was no waste of food at that time, because humans at that time could only eat two meals, not three meals a day.

By the time of the Han Dynasty, 60 million people could be fed. The specific method was also very simple. They still planted on the ridges, but changed the planting. This year it was a ridge, and next year it was dug into a ditch and filled with soil.

The ditch has turned into a ridge, which is new land. It will be replaced next year.

By the end of the Han Dynasty, the population reached 55 million. At this time, there was not enough food, so the world was in chaos and began to kill people.

The same was true in the Tang Dynasty. Changes did not occur until the Song Dynasty. The Song Dynasty introduced tropical rice, which could feed 100 million people.

And from now on, everyone can eat three meals a day.

At the end of the Song Dynasty, if there was not enough food, then kill them.

The same was true in the Ming Dynasty. At the end of the Ming Dynasty, it could only feed 100 million people. At this time, the population was too large, and the Ming Dynasty was in danger.

At this time, the Ming Dynasty introduced sweet potatoes, also known as sweet potatoes, which have many other names. Unfortunately, they were just introduced and there were not so many seedlings planted across the country. Therefore, the Ming Dynasty had no time to catch their breath and they were wiped out. It was a pity.

In the Qing Dynasty, the rulers of the Qing Dynasty took advantage of the Ming Dynasty. They had sweet potatoes and the population increased to 400 million! They could feed 400 million people!

Unfortunately, by the end of the Qing Dynasty, it was no longer possible, and there was only enough to feed 400 million people.

Modern China has about 1.4 billion people. Why? Because of advanced chemical fertilizers and the research of super rice by Yuan Longping, the fields do not need to rest and the super rice has high yields.

As soon as these things appeared, China's population immediately surged, and its GDP ranked first in the world.

Therefore, for ancient feudal rulers, whether their kings were wise monarchs had little to do with the common people.

It doesn’t matter if you are a centralized or democratic world.

What does it have to do with? Grain production! Food is the first priority for the people. First of all, they have to eat enough. Who will make trouble if they are full? If you don’t have enough, I’m sorry, I can’t live anymore, so you will die too.

Therefore, the main thing that humans, advanced animals with self-awareness, think about is not that there is not enough food to eat, but I will sacrifice my life for righteousness.

They will sum up a reason not to commit suicide, and also to want others to die. What reason? This regime is not good, the ruler is stupid, let’s revolt!

Once the war breaks out, people are dead, social conflicts are gone, and everyone is back to where they started. No one is richer than anyone else, and no one is poorer than anyone else. Don't laugh at me. I can't laugh at you. Everyone is the same.

.

Such a society can develop again.

Speaking of which, it is just a belly problem, and because it has a strong self-awareness, ordinary animals will not want to commit suicide.

Human beings do it because of self-awareness.
