Doomsday Bunker Upgrade

Of course, Chen Xin could see Mo Qingyan's desire to have a pet. After all, she had always wanted to have a cat before the disaster.

It's just that on the one hand, she didn't have time to raise a cat because of the relationship with the store, and on the other hand, it was also because she tried it once, but she met a black-hearted merchant and the kitten she sent died within two months. 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 as before.

And after the disaster, it is even more impossible to keep pets. People don’t necessarily have enough to eat. How can there be extra food to raise cats?

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

It is not a very labor-intensive task to breed a cat for her as a pet through laboratory methods.

Moreover, Chen Xin is also seriously considering whether to allow pet breeding in the dome city.

It's just that Chen Xin didn't know much about it, so he decided to ask more knowledgeable experts.

"Professor Li, how is your health? Are you feeling better? You have to 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 lose energy when they are old. In addition, the body is indeed deteriorating and aging. A small illness may develop into a serious one.

So even though Professor Li himself said that there is no need to mobilize teachers for a small problem, Tang Tang still did not dare to neglect to arrange doctors and the best convalescent ward for Professor Li to recuperate.

Professor Li was also very happy to see Chen Xin, and after a few words of pleasantries with him, he asked about work.

"You don't have to worry about work. Director Tang will take care of it. Besides, aren't your students trained by you? You still can't trust them?" Chen Xin explained to Professor Li about the recent work of the scientific research center. The matter, he comforted the old professor.

Facing Chen Xin's comfort, Professor Li smiled and said: "I know my students, although they are all good, but they are still inexperienced, and they need me, an old man, to check them. This can be regarded as my old man's point. Be stubborn, you are always worried about these young people, it is also the old man's old problem, always restless, and love to worry about this and that."

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

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

"Professor, the country is currently preparing to build a dome city, and an ecological system needs to be built in the city. At present, the scientific research center is organizing the cultivation of animals and plants. Which animals do you think are mainly needed in this regard?" Chen Xin humbly asked Professor Li for advice. with.

Hearing Chen Xin's question, the cheerful expression on Professor Li's face suddenly became serious, and he answered after thinking carefully: "This question is difficult to answer! Animals in the urban environment before the disaster It is 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.

Added to this are domesticated and introduced animals, which together make up wildlife populations in urban environments, but are only part of an overall ecosystem.

Fish and shrimps, frogs, plankton, microorganisms in the river, and even humans living in the city can actually be included in the animal groups in the entire ecosystem. "

Professor Li's words made Chen Xin raise his eyebrows. At the same time, he quickly took out a notebook and recorded what Professor Li said.

Seeing that Chen Xin took out his notebook to record, Professor Li also adjusted his thinking, and said more seriously: "From the perspective of a city, the two major groups of animals and plants in the city's ecological system must be connected. See, for example, if you are doing greening in an urban area, you have to consider whether there is a relationship between the animals you put in and the greening plants you use.

If the animals you put in cannot eat the plant, or if it will cause poisoning after eating, etc., these are issues that need to be considered.

So we need to look at them together, 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, even consumers, is also a producer .

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

Insects mainly feed on plants. Although we have always managed and killed all kinds of insects as much as possible in the past, this is actually not a good thing for the ecological cycle. So in this regard, I suggest Comrade Xiao Chen If you pay more attention, you should still focus on control as much as possible. If any link in the food chain is missing, it will not work. "

Hearing what Professor Li said, Chen Xin also felt that this matter needs to be more cautious, so he nodded, recorded Professor Li's words, and marked them emphatically.

After talking about this topic, Chen Xin also asked Professor Li: "Professor, do you think it is appropriate to allow pets to be kept in the dome city built in the future?"

"If you ask me this question from the perspective of the 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, if there are pets in a city, It is still necessary to seriously consider the impact they bring." Speaking of this, Professor Li seemed to be a little out of energy and looked a little tired.

Seeing this, Chen Xin didn't continue talking, but said some polite words to Professor Li, such as taking a good rest, and then left.

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

To build a balanced ecosystem, it is necessary 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.

So this matter should be left 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.
