"Recently, there is a related project in Vientiane, and I would like to know from you. After all, you're also a student of biology. ”

Song Shuqing nodded: "Invasive plants, that is, plants in invasive species." ”

"Due to geographical isolation, the reproduction and evolution of organisms have a certain degree of independence. Therefore, each region will have its own unique organisms, which contain each other and constitute a relatively stable ecological environment. ”

"But in modern times, humans have mastered great transportation capabilities. Along with this ability, some unique species are also carried into unfamiliar environments, including animals, plants, microorganisms, ......"

Song Shuqing talked eloquently: "For example, when the American continent was discovered, a large number of bacteria unique to Europe were carried to the Americas, and countless Indians died as a result. ”

Lin Han frowned and asked, "Then why didn't the bacteria in the Americas infect Europeans?"

Song Shuqing explained: "Because the Indians are a very small number of people, a race that has been produced after a long period of reproduction. In other words, their gene pool is far more homogeneous than that of the Eurasian and African plates, and their immunity to some pathogens is weaker. Of course, there are also reasons for the backward level of medical care. ”

"All in all, invasive species, like these viruses, are not 'immune' due to the lack of natural predators, and are able to multiply on a large scale, seriously damaging the local ecological environment. ”

Song Shuqing continued: "Theoretically, after a long period of time, such invasions can be overcome by nature. ”

"The way of heaven is to make up for what is lacking...... Over-reproduced populations will sooner or later give birth to corresponding natural enemies, or have to enter the process of self-destruction due to the shackles of living space. ”

"It's just that compared to the historical development of human beings, this natural process is too long and tragic, so species invasion is regarded as a serious ecological disaster. ”

He paused: "As far as invasive plants are concerned, there are about a few hundred species in the entire territory of China, and the number is still rising. ”

Speaking of this, he couldn't help but shrug his shoulders: "After all, all invasive species are never preventable...... When I was at Peking University, I witnessed a few people from outside the university who were planning to release Brazilian turtles in the lake. ”

Lin Han was stunned: "Brazilian tortoise, I remember that thing is known as an ecological killer, right?"

"yes. Fortunately, we stopped it, otherwise those ecological killers would have entered the lake, and the environment of Peking University would have suffered. ”

Song Shuqing frowned, as if he remembered something unpleasant, and said indignantly: "As soon as I think about it, I get angry, those few people who plan to release the turtle actually say that we hinder them from making merits, it's just ...... Naive！”

Lin Han smiled: "The release of life also has to be in accordance with the Basic Law, it seems that they still have to learn one." ”

"It's not a question of learning or not learning. Song Shuqing exhaled, "Their so-called goodness and faith are just seeking benefits for themselves through gods and Buddhas, and the essence is greed." To despise science is to be pure ignorance. ”

"Greed and ignorance come together, not to mention learning one, learning several doesn't work......"

Lin Han thought for a while: "Actually, we are planning to clean up the invasive plants in Handong Province recently, do you have any suggestions?"

Song Shuqing looked at him and said with a smile: "Cleaning up invasive plants? This is a thankless job, isn't Vientiane a technology company that has broken the head of the Allied camp and the Soviet Russian camp, when did it become so lo?"

Not long ago, the beta version of "Red Alert 2: Senluo Everything" has been circulating in a small area.

In this Red Alert mod, the Weather Controller, Chrono Teleportation, Iron Curtain Device, etc., are all related to Vientiane. Vientiane Company has become synonymous with black technology.

Lin Han laughed: "Of course it's not an ordinary cleanup. ”

Song Shuqing was stunned for a moment, and then asked, "What, what is the unexpected technology?"

"Almost, it's very efficient to clean up anyway. Lin Han said, "There are hundreds of invasive plants in China, what is the situation in Handong?"

Song Shuqing touched his chin and thought for a while: "When I first went to college, I read an article that said that there are more than 30 kinds of invasive plants in Handong, and now there should be 40 species." ”

"For example, 'goldenrod canadensis', 'water hyacinth', 'water peanut', etc., are all species that are more seriously invaded......"

Song Shuqing said: "The cleanup of invasive plants is not very profitable. But if your skills are really good, the money is also very bright. ”

"How bright is it?"

Song Shuqing smiled: "If you can get Handong Province, the annual revenue of one billion yuan is estimated to be no problem, and the specific profit depends on you." According to Vientiane's past profitability, it should not be a problem to earn hundreds of millions. ”

One province is one billion a year...... That's a lot of money.

However, advanced biological privileges allow invasive plants to die directly and in large areas, which can be regarded as a permanent cure. If you charge a fee, you basically don't have to charge it once.

As for the invasive plants to reproduce on a large scale again, it is estimated that it will take a long time.

Lin Han nodded slightly: "Nationwide, can there be tens of billions?"

"It is estimated that it is only 10 billion, and Handong Province is a more severely affected area after all. In desolate areas such as Xinjiang and Tibet, there are certainly not many invasive plants. ”

"Nationwide, the disaster of invasive plants is more serious, basically that is, East China, South China, such as Jiangsu, Zhejiang, Fujian, etc. Song Shuqing said.

"Among the invasive species in Handong Province, plants are the majority, and they are right in front of you. If you want to start governance, just contact the relevant local authorities, as long as the technology is excellent, they will definitely be more active than you. ”

Lin Han suddenly asked, "Can you be more specific?"

As the most mysterious department of the Celestial Empire, the relevant departments can be said to be elusive.

Song Shuqing thought for a while: "The main responsibility for the problem of invasive species is generally the agricultural department, followed by the environmental protection, quality inspection, and forestry departments. Well, that's pretty much it. ”

"Agricultural department?" Lin Han's eyes lit up.

"Aren't you the deputy director of the Agricultural Bureau of Nanshui County, how is the situation of invasive plants in Nanshui County?"

Song Shuqing was stunned: "Uh...... Haven't I taken office yet? When I get to the Agricultural Bureau, I'll help you check. ”

Lin Han said with a smile: "As soon as you took office, you solved the problem of invasive plants, and it seems that your future is also very bright." ”

"If only the fees could be less...... That's even better. ”

Lin Han patted Song Shuqing on the shoulder: "It's good to open and govern for free." ”

Nanshui County is more than 1,000 square kilometers, and according to the coverage capacity of high-level biological authority, it is almost the same to drive around casually.

"It's not early, I'll send you to the Agricultural Bureau. ”10
