"It's really the second time, and I just have some questions I want to ask Liu Gongzi for."

Hearing Liu Jin's words, Emperor Hongzhi nodded and said.

Originally, he just came out to see how ordinary people in the capital coped with the cold winter, but he didn't expect to meet Liu Jin, he originally had a lot of questions to ask Liu Jin, and he just took this opportunity to ask.

The same is true for Liu Jian, Xie Qian, and Li Dongyang, they also have a stomach of questions to ask Liu Jin, and now they just happened to encounter it, so naturally they don't plan to let Liu Jin go easily.

"Don't dare to ask for advice, if Mr. has any doubts, you might as well say it directly, as long as I know, I absolutely know everything."

In front of Emperor Hongzhi, Liu Jin naturally had to be modest.

"Yesterday in the Moon Tower, I listened to Childe's high talk, such as Daigo empowerment, mouth plug suddenly, I stayed awake all night, constantly thinking carefully about what Childe said."

"Among them, about the monsoon, once the monsoon is too fast or too slow, it will inevitably flood in the south and drought in the north or drought in the south and flood in the north, but since ancient times, whether it is a drought in the south and a drought in the north or a drought in the south and a flood in the north, the place where the problem occurs is the north, and there have always been few problems in the south."

"For this point, I also consulted a lot of historical materials last night, and it is indeed as Gongzi said, but I thought about it all night, and I still don't understand why this problem appears in the north, but there are few problems in the south."

Hongzhi looked at Liu Jin, but he didn't mean to be polite to Liu Jin, and thought about it and asked the question that he hadn't figured out all night last night.

He is the emperor, and his greatest concern is naturally the problem of the perpetuation of the country, and he also knows that the change of dynasties in all dynasties actually started with the problem of peasant uprisings.

One of the direct reasons for the inability to survive is the disaster, the failure of the grain harvest in the field, and other factors, such as land annexation, corruption of officials, invasion of foreign enemies, etc., which led to the change of dynasties.

Emperor Hongzhi has been familiar with history since he was a child, and he has been taught by famous teachers, and he has read a lot, a lot of the history and summaries of all dynasties, and knows this very clearly.

Therefore, when I heard Liu Jin say that the monsoon has something to do with the change of dynasties, I am also very concerned, and I have been thinking about this question, trying to find the answer from it, and then find a way to make their old Zhu family permanent.

Hearing Emperor Hongzhi's words, Liu Jian, Xie Qian, and Li Dongyang, who were present, also immediately came to their senses, and they all cheered up, wanting to listen carefully to what Liu Jin could say.

As for the owner of the charcoal shop, Qian Youcai also looked like he was listening to him at this time, men, they all like to point out the country, and boast about it, and now I am fortunate to hear Liu Jin talk about this content, how can I miss it.

The matter of this coal business is put aside for the time being, but he now knows that this Mr. Zhu is very extraordinary, and he can do business with him, and he will also have a big backer in the future.

Hearing Emperor Hongzhi's question, Liu Jin pondered, and thought quickly in his mind, history has also been studied, and Emperor Hongzhi's question is actually difficult to answer, if you really want to say the answer, in fact, it can only be said that it is due to the destruction of nature by human development.

After sorting out his language slightly, Liu Jin slowly said: "Actually, it is not difficult to answer this question. ”

"The northern Central Plains, especially the Hanzhong Plain, are the birthplace of our Chinese descendants, and these regions have always been economic, political, and demographic centers."

"In the southern region, the Spring and Autumn Period and the Warring States Period began to slowly and gradually develop, and it was not until the Tang Dynasty that the southern Jiangnan region slowly became an important economic region, and now, it has become an important source area of grain tax in our dynasty."

"This northern region, because of its long history, long development time, large population, and the change of dynasties in history, etc., the vegetation in this northern region has been seriously damaged."

"Why there will be serious problems in the north once there is a disaster, in fact, in the final analysis, it is related to the environment and the forest."

Liu Jin made a surprising statement, blaming the environment and forests for the famine-prone situation in the north.

"Environment?"

"Forest?"

Emperor Hongzhi, Liu Jian, Xie Qian, Li Dongyang and others were dumbfounded, they had thought of countless theories in their minds, but for the first time, they heard that it was related to the environment and forests.

"Liu Gongzi, how can this environment and the forest have something to do with the disaster?"

Xie Qian was confused, he couldn't figure it out, and there was no way to implicate the relationship between the two.

"Of course it does, and it's very big."

Liu Jin said with a smile.

"We all know that in the Qin and Han dynasties, this Guanzhong area was the core area, and at that time, the Guanzhong area was lush with vegetation, dense forests, and a very good ecological environment."

"But as time went by, the population grew, and ordinary people cut down more and more forests, and more and more farmland was cultivated, so the forests gradually disappeared and became countless fertile fields."

"Isn't it good to turn this reclaimed wasteland into fertile land?"

Hearing this, Liu Jian couldn't listen to it anymore, all dynasties and dynasties encouraged reclamation and land reclamation, and when Liu Jin came here, it seemed that this land reclamation was a bad policy.

"I'm not saying that it's bad to open up the land, but I'm just saying that the land has destroyed the vegetation and the forest on a large scale."

"In the Qin and Han dynasties, Shaanxi was a fertile wilderness, with beautiful mountains and forests, and even in the Tang Dynasty, the environment of Shanxi and Shanxi was still very good, but now, I don't know if any of you have been to Shaanxi and Shanxi, and it has become the Loess Plateau."

"Without vegetation cover, when this rain washes away, all the fertile soil is taken away, and the environment is getting worse and worse, and the worse the environment, the weaker the resistance to natural disasters, and once there is a problem, it will immediately cause a huge famine."

Liu Jin naturally will not argue with Liu Jian about the matter of reclamation of land, this is something that has been encouraged by all dynasties, and if he opposes it, there is absolutely no good end, and he needs to prove from another angle that this reclamation of land is not necessarily good, and it also has great drawbacks.

"The northern region, because it has always been a population center, a political center, and an economic center, as the population grows, the environment in the northern region becomes more and more fragile, just like here on the Loess Plateau, and the ability to resist natural disasters becomes worse and worse."
