Chapter 512: Grassland Degradation

After hearing Wang Yong say that the Grassland Autonomous Region wanted Wang Yong to help control the degradation of grasslands, Dawei was not surprised. He also went to see the large-scale desalination plant built by Wang Yong before, and the production of millions of tons of fresh water a day attracted a lot of people's attention.

"I want you to bring fresh water, right?"

According to Dawei's idea, there must be a lot of places on the grassland that lack water, so he wants Wang Yong to sell water to them. If there is enough water in the prairie, then the rest of the problems are not a problem.

"It's not that simple!"

Wang Yong's answer obviously made Dawei stunned, what? Isn't that what happened? Isn't it about helping to control grassland degradation? How can you treat it without water?

Wang Yong saw the doubts in Dawei's heart, but he didn't rush to explain, but took out the special white cigarette in his pocket, took out one and put it in his mouth, and then signaled the cigarette case to Dawei.

As a chef, Dawei is very self-disciplined, although he occasionally smokes when socializing, but he is really not addicted to it, and it is dispensable. And, almost every time I smoke, I will always be counted down by the fat man.

Because this kid's so-called cigarette is just spit out after turning around in his mouth, and he doesn't swallow it. So it's not for nothing that the fat man said that it was a waste to smoke for him.

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

"Grassland degradation isn't just about water shortage, it's just because of water shortage, as you might think, it's so easy to do, it's not a matter of effort at all."

As he said this, Wang Yong remembered the poisoning incident he had encountered on the prairie. I don't know how they handled it? How much damage did that time take?

"What other reason could there be?" Dawei was obviously interested in this matter, and Wang Yong didn't know how to tell him with a posture of breaking the casserole and asking the end.

After thinking about it, Wang Yong felt that it was better to tell him a little. Even if it's to give him a science popularization.

"You're just lazy, won't you go to 100 degrees by yourself? I'm going to send a kind heart today and give you some science. ”

Regarding Wang Yong's statement, Dawei also rolled his eyes with a big eye. He knew that Wang Yong had a wide range of knowledge, but he also knew that Wang Yong had always been easy to read and not to understand, and he knew a little about everything, nothing more.

If you really let him make it clear in that aspect, he will definitely have to show his stuff, unless he has prepared beforehand. However, judging from his expression when he received the call, he was obviously unprepared.

It's just that David doesn't know. Wang Yong has such a demonic super light brain in his body. When Wang Yong was about to talk about this topic, Xiaoguang had already found out some information he had searched on the Internet.

"Grassland degradation is the decline of grassland vegetation, and the main expression is that the quality and yield of forage per unit area have decreased significantly. It is also a major manifestation and harbinger of land desertification. ”

Seeing that what Wang Yong said was the truth, Dawei really couldn't understand it. Did this guy really do his homework beforehand? Otherwise, why would he have opened his mouth and come?

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

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

At present, the main reason for the degradation of grasslands in China is recognized as human activities. The main table is overgrazing and indiscriminate reclamation. Indiscriminate mining of underground mineral resources, etc.

The ultimate result of grassland degradation is land desertification, so it is not only the degradation of grass, but also the degradation of "land", which is the inevitable result of human overuse of nature.

At present, the state has also taken many measures to deal with the increasingly severe problem of grassland degradation. For example, changing the habits of grassland herders and changing the nomadic grazing style of herders to fixed-point grazing. For example, in a certain area, the ban on grazing, etc.

Among them, the enclosure and grazing ban is the most economical way to restore degraded grassland, but it is difficult to implement this method because of the need to take into account the interests of herders.

Therefore, we must first consider how to change the way of life of herders, who make a living from grazing.

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

However, Wang Yong does not have to worry about this problem, since the government of the Inner Mongolia and Ancient Autonomous Region has found him through Uncle Guò Battle. Then you must be facing the kind of place that has almost become a desert.

That kind of place can no longer be said to be pasture, and I am afraid that there are no herders to go back there to graze. Why are you driving your cattle and sheep there when you can't find enough grass and water?

"Oh, you're saying that grassland degradation is mainly caused by human factors, but it's also due to water shortages? If there is water, can there be a shortage of weeds? ”

Dawei obviously didn't understand it yet, and still said strongly.

"It's not all grass, didn't you hear me say that there is also a problem with the quality and yield of the pasture? Why Import Grass Seeds from Abroad? Of course, there are also various high-quality pastures in the country. ”

"Why?" This time, Dawei was very cooperative and obediently asked his doubts.

"The quality of 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 more resistant to disease, but also make their meat quality better and can be sold at a higher price!"

"I don't understand!"

Looking at Dawei, who shook his head, Wang Yong also scratched his head, not knowing how to explain this matter. I thought for a while, organized the language, and then spoke again.

"Let's put it this way, a piece of pasture of the same area is only enough for ten sheep to eat, and you put in a hundred or even a thousand sheep, imagine for yourself, even if there is a big lake next to it, is it so useful?"

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

"You mean there's not enough grass to eat?"

"That's what it means! In fact, it's much stricter than this. You know that sheep don't just eat grass leaves, there are many kinds of sheep that even dig out the roots of grass and eat them if they can't eat enough. ”

Wang Yong's words made Dawei suddenly think of an article he had read in a magazine. It says that a certain place is a large farmer who breeds goats, and every household breeds goats.

As a result, because there were too many of them, there were not enough weeds on the mountain to eat, and even the grass roots were eaten. The following spring, the entire mountain became bare, causing great safety hazards and environmental disasters.

Dawei immediately made up a picture in his mind: in a vast prairie, countless herds of cattle and sheep occupied their respective positions one by one, constantly gnawing on the small amount of grass on the ground, while moving, and soon gnawed a large area into white ground.

As a result, after a gust of wind, the fertile soil on the ground was quickly lifted by the strong wind, and it drifted away in the direction of the wind towards an unknown place in the distance.

It didn't take long for it to become more and more desolate, and eventually, it slowly became a desert with no people.

"Also, you've heard that they're particularly rich in resources, right?"

"What do you mean? Mineral? Colliery? ”

Dawei seems to understand what Wang Yong means, these things have been hard currency in the past ten years, and their prices have been rising. In order to dig up these resources, then the destruction of the pasture is unavoidable.

"Let me tell you something you don't know, a coal mine belonging to Wuda Mining Company, a subsidiary of Shen*hua Group, has been spontaneously combusting since 61, and the underground fires have not been extinguished. Imagine for yourself, how many tons of coal have been burned in these decades? ”

"Isn't it? How can it be? ”

Dawei had really never heard of this, and it was completely beyond his imagination. In his impression, coal is dug from the ground, and generally coal mine accidents are either water penetration accidents or gas explosions, and he has never heard of coal mines catching fires, and they cannot be extinguished for decades.

"What is this? And what about coal mine fires that have been burning for hundreds of years? ”

"What you say is true?"

This is obviously beyond Dawei's imagination, the coal mine fires are all underground, so it is not easy to extinguish? If nothing else, there is no water, as long as the mining hole is backfilled, there is no air, and it will soon be extinguished by itself?

"Nothing is impossible, think about it, what has become of the ground after all these years of fire burning under the ground?"

Wang Yong glanced at Dawei and did not continue. There was no need for him to say anything more, Dawei himself thought of it. The first thing he thought of was the Flaming Mountain in "Journey to the West".

Dry and hot, no grass, no living things, so to speak, extinct, desolate, worse than a great desert.

"And because of the coalfield fires, not only do you burn some coal for nothing, but it also has an irreparable impact on the environment. For example, emitting large amounts of greenhouse gases and changing the local climate. In addition, after combustion, the metallic and non-metallic elements in the coal become acidic or alkaline compounds, which causes severe pollution to the groundwater near the fire area. ”

"What kind of pollution law?"

"The acidity and alkalinity of the water is too large, that is, it will not be used to water the ground, and what will die when watered!"

"Oh, there's so much more! By the way, how do you know so clearly? Honestly, did you do your homework beforehand? What are you thinking? ”

"What can I do? It's not that some time ago, someone above sent a message, wanting me to contract a degraded grassland, and try to help solve the problem of grassland degradation that is becoming more and more severe in Inner Mongolia and ancient times, but I have checked the information for several days! ”

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

"Pick it up! Why don't you take it! (To be continued......)
