Dawei was not surprised to hear Wang Yong say that the Grassland Autonomous Region wanted Wang Yong to help manage the degradation of the grassland. He also visited the large seawater desalination plant built by Wang Yong before, and the daily freshwater production of millions of tons has attracted a lot of attention.

"Do you want to transport fresh water?"

According to Dawei's idea, there must be many places on the grassland that are seriously short of water, so I want Wang Yong to sell water to them. If there is enough water source on the grassland, then the remaining problems will not be a problem.

“Not that simple!”

Wang Yong's answer obviously made Dawei stunned. Why? Isn't that the case? Didn't it mean to help control the degradation of the grassland? How to control it without water?

Wang Yong saw the doubts in Dawei, but he did not rush to explain. Instead, he took out the special white cigarette in his pocket, took out one and held it in his mouth, and then signaled Dawei the cigarette box.

As a chef, Dawei is very self-disciplined. Although he smokes occasionally during social events, he is really not addicted and dispensable. Moreover, he is always scolded by fat people when he smokes almost every time he smokes.

Because this kid said that smoking was just a circle in his mouth and spit it out, and he didn't swallow it. So it's not unreasonable for the fat man to say that smoking for him was a waste.

Dawei waved his hand and signaled not to smoke. Wang Yong took out his lighter and lit the cigarette in his mouth. He took a deep breath, and after a while, two smoke came out of his nostrils.

"The degradation of grassland is not just a problem of water shortage. If it is just because of water shortage, it will be very easy to deal with, and there is no need to worry about it."

When he said this, Wang Yong remembered the poisoning incident he had encountered on the prairie. He didn't know how they handled it? How much of the losses caused by that time?

"Where are there any other reasons?" Dawei became obviously interested in this matter. His attitude of breaking the casserole and asking the whole thing made Wang Yong not know how to tell him.

After thinking about it, Wang Yong thought he should tell him something. Even if he gave him some popular science.

"You are just lazy and won't go to Baizhai by yourself? I'll be kind today and give you some science."

Dawei rolled his eyes on Wang Yong's statement. He knew that Wang Yong had a wide range of knowledge, but he also knew that Wang Yong was always a good person but did not seek to understand much. He knew a little about everything, that's all.

If you really want him to explain it clearly in that aspect, he will definitely have to reveal it unless he has prepared it in advance. However, judging from his expression on the phone, this matter was obviously not prepared.

But Dawei didn't know. Wang Yong had such a monster super light brain as Xiao Guang in his body. When Wang Yong was about to talk about this topic, Xiao Guang had already found some of the information he had searched on the Internet.

"Grassland degradation means the decline of grassland vegetation, which is mainly manifested in the significant decline in the quality and yield of grass per unit area. This is also a main manifestation and omen of land desertification."

Seeing Wang Yong talking very well, Dawei really couldn't understand. Could it be that this guy had done his homework in advance? Otherwise, why would he just open his mouth?

Wang Yong didn't care about how Dawei thought about himself, and he told himself some of the content about grassland degradation that he had searched on the Internet.

The main reason for grassland degradation is not just water shortage, because grass is not a crop, it is one of the most drought-resistant plants in nature.

At present, regarding the degradation of grasslands in China, the most recognized main reason is human activities. The main manifestations are overgrazing, random reclamation, random mining and underground mineral resources.

The ultimate result of grassland degradation is land desertification, so it is not only the degradation of grass, but also the degradation of "land", and is the inevitable result of human beings' excessive use of nature.

At present, the country has also taken many measures to deal with the increasingly serious grassland degradation problem. For example, changing the habits of grassland herders and changing the nomadic grazing method of herders to fixed-point grazing. For example, banning grazing in certain areas, etc.

Among them, the sealing and grazing ban is the most economical way to restore degraded grasslands. However, because the interests of herders are taken into account, this method is quite difficult to implement.

Therefore, we must first consider how to change the survival method of herders. Herders make a living by grazing.

If there is no pasture, then they will not be able to feed enough cattle and sheep, and they will not be able to survive.

However, Wang Yong didn't have to worry about this problem. Since the Inner Mongolia Autonomous Region Government came to him through Uncle Bater, what he had to face was definitely the kind of place that had almost become a desert.

That kind of place can no longer be said to be a pasture, and I am afraid that no herders will go back to grazing there. If you can't find enough grass and water, why should you drive cattle and sheep there?

"Oh, what you mean is that grassland degradation is mainly caused by human factors, but that is also due to lack of water? If there is water, can we still lack weeds?"

Dawei obviously didn't understand yet, and he still said in a slight sense.

"Not all grass is OK. Didn't you hear me say there is a grassland quality and yield problem? Why do you need to import foreign grass seeds? Of course, there are also various high-quality grasses in China."

"Why?" This time Dawei cooperated very much and obediently asked his doubts.

"The quality of the forage determines the quality of cattle and sheep and the interests of herdsmen. Good forage can not only make cattle and sheep grow faster and resist diseases, but also make their meat better and sell at a higher price!"

"not understand!"

Looking at Dawei who was shaking his head, Wang Yong also scratched his head, not knowing how to explain this matter. After thinking for a while, he organized the language before speaking again.

"Let me put it this way, a piece of grassland with the same area is only enough for ten sheep to eat. If you put in a hundred or even a thousand sheep, you can imagine it yourself, is it so useful even if there is a big lake next to it?"

This time, Dawei seemed to understand something, and did not immediately refute and ask a question, but thought quietly for a while before looking up at Wang Yong.

"You mean, there is not enough grass to eat?"

"That's the same! In fact, it's much more serious than this. You know that sheep eats grass, but they don't only eat grass leaves. If there are many kinds of sheep who are not full, they will even dig out the grass roots to eat."

Wang Yong's words made Dawei suddenly think of an article he had read in a magazine. It said that somewhere is a large goat breeder, and every household raises goats.

As a result, because there were too many wild grasses on the mountain, even the grass roots were eaten up. The following spring, the entire mountain became bare, causing great safety hazards and environmental disasters.

Dawei immediately thought of a picture in his mind: on a vast prairie, countless flocks of cattle and sheep occupied their respective positions one by one, constantly gnawing at the not many grasses on the ground while moving, and soon turned a large area into white ground.

As a result, after a strong wind, the fertile soil on the ground was quickly raised by the strong wind, floating along the wind direction to an unknown place in the distance.

Not long after, the place became more desolate, and finally, it slowly turned into a large desert without people.

"Also, have you heard that their resources are particularly rich?"

"What are you referring to? Minerals? Coal mines?"

Dawei seemed to understand what Wang Yong meant. These things have been hard currency in the past ten years and prices have been rising. In order to dig out these resources, it is inevitable to damage the pasture.

"Tell you something you don't know. A coal mine affiliated to the Wuda Mining Company, a subsidiary of Shen*hua Group, has spontaneous combustion since 1960s, and has not yet put out the underground fires. Just imagine how many tons of coal have been burned in the past few decades?"

"No, right? How is that possible?"

Dawei has never heard of this, and it is completely beyond his imagination. In his impression, coal is dug from the ground. Generally, there are either water permeability accidents or gas explosions in coal mines. I have never heard of coal mines catching fire, and it can't be extinguished for decades.

"What's this? What about coal mine fires that have been burning for hundreds of years?"

"What you said is true?"

This is obviously beyond Dawei's imagination. The coal mine fires are all underground, so is it not easy to extinguish? Not to mention anything else, there is no water. As long as the mining hole is backfilled, there is no air, will it be extinguished soon?

"Nothing is impossible. Think about it, what will the ground turn into after the fire that has been burning under the ground for many years?"

Wang Yong glanced at Dawei and did not continue to say anything. He didn't need to say anything else. Dawei himself thought of it. The first thing he thought of was the Flame Mountain in "Journey to the West".

It is dry and hot, and there is no grass growing, and there is no living creature. It can be said that it is extinct and desolate, which is worse than a large desert.

"And because of the coalfield fire, it not only burns some coal in vain, but also has irreversible harsh effects on the environment. For example, the emission of a large amount of greenhouse gases will change the local climate. Also, after combustion, the metals and non-metallic elements in the coal become acidic or alkaline compounds, causing serious pollution to the groundwater near the fire zone."

"What kind of pollution method?"

"The pH of water is too high, so it can't be used to water the ground. Whatever watering is killed!"

"Oh, there are so many things left! By the way, how do you know so clearly? I honestly explain, have you done your homework in advance? What are your ideas?"

"What can I do? Some time ago, someone from above said that I wanted me to contract a degraded pasture and try to help solve the increasingly serious grassland degradation problem in Inner Mongolia. I have been checking the information for several days!"

Dawei looked like this, stared at Wang Yong for a while, and asked, "Then do you have any plans from above? Are you going to take on this job?"

"Come on! Why don't you!" (To be continued, please search Piaotianwen, novels are better, updated and faster!
