Doomsday Bunker Upgrade Chapter 523: Conversation with Professor Li

Chen Xin certainly saw Mo Qingyan's desire to have a pet, after all she had always wanted a cat before the disaster.

On the one hand, she didn't have time to raise a cat because she was running a store, and on the other hand, she tried once, but met a black-hearted businessman and the kitten died within two months. , which left a big psychological shadow on Mo Qingyan.

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

And after the disaster, it's even more impossible to keep pets. People don't always have enough to eat. How can there be extra food to keep cats?

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

It is not very difficult to breed a cat for her as a pet through laboratory means.

And Chen Xin is also seriously considering whether to open pet breeding in the dome city.

It's just that Chen Xin doesn't know much about this, so he decided to ask a more knowledgeable expert.

"Professor Li, how is your health? Are you feeling 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.

Actually, Professor Li's condition is not serious. It's just that people are not very energetic when they are old. In addition, the body is indeed deteriorating and aging. A small illness may develop into a major problem.

So even though Professor Li himself said that there is no need to mobilize teachers for a small problem, Tang Tang did not dare to neglect the arrangement of the doctor and the best convalescent ward, so that Professor Li could cultivate well.

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

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

Facing Chen Xin's comfort, Professor Li smiled and said: "I understand my students, although they are all good, but they are still inexperienced, and I need an old man like me to check them out. The old man is a little stubborn, he is always worried about these young people, it is also the old man's old problem, he is always restless, and he likes 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.

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

"Professor, the country is currently preparing to build a dome city, and an ecological system needs to be built in the city. Currently, the scientific research center is organizing the cultivation of animals and plants. What animals do you think are mainly needed in this area?" Professor Li asked.

Hearing Chen Xin's question, Professor Li's originally cheerful expression suddenly became serious, and he answered after thinking for a while: "This question is not easy to answer! Before the disaster, the urban environment The animals below are mainly wild animals that survived from the urban development process, mainly small animals such as mice, insects and birds, and large wild animals are extinct in the city.

In addition to this are domesticated and imported animals, which together make up the wild animal population in the urban environment, but they are also only part of the overall ecosystem.

Like fish and shrimps, frogs, plankton, microorganisms in the river, and even human beings living in cities, they can actually be included in the group of animals in the entire ecosystem. "

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

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

If the animals you put in can't eat this plant, or if there is a poisonous reaction after eating, these are all issues to consider.

So we need to put them together 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 each member of them can even be consumers. Also a producer.

For example, if you want to put birds, as consumers in the ecosystem, the food that birds need is mainly insects, then you have to put insects to meet the consumption needs of birds, and birds They are also producers themselves, and 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 regard I suggest Comrade Xiao Chen, pay more attention, and try to control as much as possible. No link in the food chain is missing. "

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

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

"If you ask me this question from the perspective of ecological environment~IndoMTL.com~ 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 the impact they will bring." Speaking of which, Professor Li seemed to have a little energy and looked a little tired.

Chen Xin didn't say any more after seeing this. He just 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 putting them together.

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.

So this matter is still left to more professional people to study. Until they come up with a feasible solution and verify that the solution is feasible, it is better not to mess around.
