Doomsday Bunker Upgrade

Chen Xin certainly saw that Mo Qingyan wanted to keep a pet. After all, she had always wanted to keep a cat before the disaster.

On the one hand, she didn’t have time to raise a cat because of the shop, and on the other hand, she tried it once, but the cat sent to him died within two months after encountering a black-hearted merchant. Mo Qingyan left a great psychological shadow.

This also caused Mo Qingyan to want to raise a cat on the one hand, but on the other hand she did not dare to raise a cat easily, for fear of encountering the same situation.

After the disaster, it is even more impossible to keep pets. People don't necessarily have enough food. How can there be extra food to keep cats?

But for Chen Xin now, he felt that he could satisfy Mo Qingyan's wish.

It is not very laborious to breed a cat and give her as a pet by means of a laboratory.

And Chen Xin is also seriously considering whether to open up pet breeding in the Dome City.

It's just that Chen Xin didn't really understand this aspect, so he decided to consult a more knowledgeable expert.

"Professor Li, how is your health? Is it better? You should take good care of your health!" Chen Xin came to the recuperation area of ​​the scientific research center and visited Professor Li who was receiving treatment.

In fact, Professor Li's condition is not serious. It's just that people do not have enough energy when they are old, and the body is indeed getting worse and aging, and even minor illnesses may develop into serious problems.

So even if Professor Li himself said that there is no need to mobilize the teacher for a small problem, Tang Tang still dare not neglect to arrange a doctor and the best convalescent ward, so that Professor Li can take care of himself.

Professor Li was also very happy to see Chen Xin, and after a simple greeting with him, he asked about work.

"Don't worry about work matters, Director Tang will take care of it, and your students are all cultivated by you? You still can't trust them?" Chen Xin explained to Professor Li about the recent work of the research center The matter relieved the old professor.

Facing Chen Xin’s comfort, Professor Li smiled and said, “I understand that my students are all good, but they are still inexperienced. I need to be checked by my old man. This is also a point of my old man. Be stubborn, always worry about these young people. It's also the old man's old troubles. He always can't be idle, and he still likes to worry about this and that."

Although the young people in Professor Li's mouth are actually middle-aged people in their 40s or 50s, in the eyes of Professor Li, they are still the students who listened to his lectures.

Chen Xin didn't have much to say about Professor Li's attitude. He could only continue to relieve Professor Li a few words before talking about his main purpose.

"Professor, the country is currently preparing to build a dome city, and it needs to build an ecological system in the city. The scientific research center is currently organizing the cultivation of animals and plants. Which animals do you think is mainly needed in this regard?" Chen Xin asked Professor Li humbly With.

Hearing Chen Xin’s question, the cheerful expression on Professor Li's face suddenly became serious. After thinking about it, he replied: "This question is not easy to answer! Animals in the urban environment before the disaster Mainly the wild animals that survived the urban development process, mainly small animals such as mice, insects and birds. Large wild animals are extinct in the city.

In addition, there are artificially domesticated and introduced animals, which together constitute the wild animal populations in the urban environment, but they are only part of the entire ecosystem.

For example, river fish and shrimp, frogs, plankton, microbes, and even humans living in cities can actually be included in the animal groups in the entire ecosystem. "

Professor Li's words caused Chen Xin to raise his eyebrows, and at the same time he quickly took out a notebook to record what Professor Li said.

Seeing that Chen Xin took out the notebook, Professor Li also adjusted his thinking and preached more seriously: "From the perspective of a city, the two major groups of animals and plants in the urban ecosystem must be linked. For example, if you are greening in an urban area, you have to consider whether there is a relationship between the animals you put in and the green plants you use.

If the animal you put in cannot eat this kind of plant, or it will produce a poisoning reaction after eating, these are all issues that need to be considered.

Therefore, they need to be integrated to build a stable food chain and supply-demand relationship, so that every animal and plant in this ecosystem can participate in the ecological cycle, so that every member of them is also a producer, even consumers. .

For example, if you want to put in birds, as consumers in the ecosystem, the food that birds need is mainly insects, then you must put in insects to meet the consumption needs of birds, and the birds themselves are also production In addition, their corpses and feces can be fed back to the entire ecological environment.

Insects mainly feed on plants. Although we have always tried our best to control and kill all kinds of insects in the past, this is actually not a good thing for the ecological cycle, so in this respect I suggest Comrade Xiao Chen You should pay more attention to control as much as possible. It won't work if there is no link in the food chain. "

Hearing what Professor Li said, Chen Xin also felt more cautious about this matter, so he nodded, recorded what Professor Li said, and marked it emphatically.

After talking about this topic, Chen Xin also asked Professor Li: "Then Professor, do you think it is appropriate to open up pet breeding in the future dome city?"

"If you ask me from the perspective of ecological environment, I can only say that pets can be regarded as a member of the urban ecological environment, although the impact on the urban ecological environment is not too great. But if there are pets in a city, you still need to seriously consider their impact.” At this point, Professor Li seemed a little bit tired and looked a little tired.

Chen Xin didn't say any more when he saw it. He just said some kind words such as a good rest to Professor Li and then left.

Through a conversation with Professor Li, Chen Xin understood that the construction of an ecological environment does not mean simply adding some species, but just putting them together artificially.

If you want to build a balanced ecosystem, you need to consider the relationship between each species and other species in the entire system, so that all species can coexist, which is the most ideal state.

Therefore, it is better to leave this matter to more professional people to study. Before they come up with a feasible plan and verify that the plan is feasible, it is better not to mess around.
