    ??

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

    It's just that on the one hand, she didn't have time to raise a cat because she was running a store, and on the other hand, it was also because she tried it once, but she encountered a shady businessman and the kitten died within two months. This gave her a lot of trouble.  Mo Qingyan left a big 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.

    ¡°After the disaster, it is even more impossible to keep pets. People may not have enough to eat, so how can there be extra food to raise cats?

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

    Through laboratory means, it is not a very labor-intensive task to breed a cat and give it to her as a pet.

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

    It¡¯s just that Chen Xin didn¡¯t know much about this aspect, so he decided to ask more knowledgeable experts for advice.

    "Professor Li, how is your health? Are you feeling better? You have to take good care of yourself!" Chen Xin came to the sanatorium area of ??the scientific research center and visited Professor Li who was undergoing treatment.

    In fact, Professor Li¡¯s situation is not serious. It¡¯s just that people do lose energy when they get older. In addition, the body does get worse and ages, and a minor illness may develop into a major one.

    Therefore, even though Professor Li himself said that a small problem did not require any effort, Tang Tang still did not dare to neglect and arranged for doctors and the best sanatorium to allow Professor Li to take good care of himself.

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

    "Don't worry about work matters. 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 to Professor Li the recent work of the scientific research center.  This incident comforted the old professor.

    Facing Chen Xin's comfort, Professor Li smiled and said: "I know my students. Although they are all good, they still lack experience. They need me, an old man, to check them. This is also a point of me, an old man.  Be stubborn, you are always worried about these young people, it is also an old problem of the old man, he is always restless, and he likes to worry about this and that."

    Although the young people mentioned by Professor Li are actually middle-aged people in their forties or fifties, in Professor Li's eyes they are still the students who listened to his lectures back then.

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

    "Professor, the country is currently preparing to build a dome city and needs to build an ecological system in the city. The scientific research center is currently organizing the cultivation of animals and plants. What 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. After thinking carefully for a moment, he answered: "This question is difficult to answer! Animals in the urban environment before the disaster  They are mainly wild animals that have survived the urban development process, mainly small animals such as mice, insects and birds. Large wild animals have become extinct in cities.

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

    For example, fish, shrimps, frogs, plankton, microorganisms in the river, and even humans living in cities can actually be included in the animal groups in the entire ecological system.  "

    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 Chen Xin taking out the notebook to record, Professor Li also adjusted his thinking and preached more seriously: "Looking at a city, the two major groups of animals and plants in the city's ecological system must be connected.  You 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 this plant, or will have poisoning reactions after eating it, etc., these are all issues that need to be considered.

    Therefore, it is necessary to combine them to build a stable food chain and supply and demand relationship, so that every animal and plant in this ecological system can participate in the ecological cycle, so that every member of them, even a consumer, is also a producer.  .

    For example, you wantWhen you release birds, as consumers in the ecosystem, the food that birds need is mainly insects, so you have to release insects to meet the consumption needs of birds, and birds themselves are also producers. Their corpses,  Feces can be fed back to the entire ecological environment.

    Insects mainly feed on plants. Although in the past we have tried our best to control and kill all kinds of insects, this is actually not a good thing for the ecological cycle. So in this regard, I suggest Comrade Xiao Chen  You should pay more attention and focus on 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 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 open pets to the domed city that will be 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 considered 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 their impact." At this point, Professor Li seemed to be a little out of energy and looked a little tired.

    When Chen Xin saw this, he didn¡¯t say any more. He just said some polite words to Professor Li, such as having a good rest, 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 and artificially bringing 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.

    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 this plan is feasible, it is better not to mess around.  (Remember the website address: www.hlnovel.com
