Chapter 624

Of course, Chen Xin sees that Mo Qingyan wants to have a pet. After all, she always wanted to have a cat before the disaster.

On the one hand, she didn't have time to raise a cat because she was running a shop. On the other hand, she tried it once. As a result, the kitten she sent died within two months when she met a black heart shop. This left Mo Qingyan a big psychological shadow.

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

After the disaster, it's even more impossible to keep pets. People don't have enough to eat. How can they have extra food to keep cats?

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

It's not a lot of effort to cultivate a cat and give it to her as a pet by means of laboratory.

And Chen Xin is seriously considering whether to open pet raising in Dome City.

It's just that Chen Xin doesn't know much about this. He decides to consult some experts who are more knowledgeable.

"Professor Li, how are you? Is it better? Take good care of yourself Chen Xin came to the sanatorium of the scientific research center and visited Professor Li, who was undergoing treatment.

In fact, Professor Li's condition is not serious. It's just that when people get old, they really lack energy. In addition, their health is getting worse and aging. A little illness may develop into a big problem.

So even if Professor Li himself said that he didn't need to stir up the public with a little trouble, Tang Tang still didn't dare to neglect the arrangement of the doctor and the best convalescent ward, so that Professor Li could cultivate himself well.

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

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

In the face of Chen Xin's consolation, Professor Li said with a smile: "I understand that although all my students are good, they are still inexperienced. I need an old man to guard them. This can be regarded as an old man's stubbornness. I'm always worried about these young people. It's also the old man's old fault. I'm always idle and I 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.

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

"Professor, our country is preparing to build a dome city. We need to build an ecological system in the city. At present, the scientific research center is organizing the cultivation of animals and plants. What animals do you think are needed in this aspect?" Chen Xin asked Professor Li for advice.

When he heard Chen Xin's question, Professor Li's happy expression suddenly became serious. After thinking about it carefully, he replied: "this question is not easy to answer! Before the disaster, the animals in the urban environment were mainly the wild animals left in the process of urban development, mainly mice and other small animals, insects and birds. Large wild animals were extinct in the city.

In addition, there are domesticated and imported animals, which together form the wild animal population in the urban environment, but they are only a part of the whole ecosystem.

For example, fish and shrimp, frogs, plankton, microorganisms in rivers, and even human beings living in cities can be included in the animal groups of the whole ecosystem. "

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

Seeing that Chen Xin took out the book records, Professor Li adjusted his thinking and said more seriously: "from the perspective of a city, the two groups of animals and plants in the urban ecosystem should be linked. For example, if you are greening in the urban area, you should consider whether there is a relationship between the animals you put in and the greening plants you use.

If the animal you put in can't eat this plant, or there will be toxic reaction after eating, etc., these are the problems that need to be considered.

Therefore, we need to integrate them 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, even the consumer, is 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 need to put in insects to meet the consumption needs of birds. Birds themselves are producers, and their corpses and feces can be fed back to the whole ecological environment.

Insects, on the other hand, mainly feed on plants. In the past, we tried our best to control and kill all kinds of insects, which is not a good thing for the ecological cycle. Therefore, I suggest Comrade Chen pay more attention to this aspect, and focus on control as much as possible. It's impossible to lose any link in the food chain. "

Hearing what Professor Li said, Chen Xin felt more cautious about this matter, so he nodded, recorded what Professor Li said, and made a mark.

After talking about this topic, Chen Xin also asked Professor Li, "Professor, do you think it's appropriate to open pet raising in the future Dome City?"

"If you ask me this question from the perspective of ecological environment, I can only say that pets can also 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, we still need to seriously consider their impact." At this point, Professor Li seems to be a little tired.

Chen Xin didn't go on talking about it. He just said some polite things 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 ecological environment is not to simply add some species, but to artificially gather them together.

If we want to build a balanced ecosystem, we need to consider the relationship between each species and other species in the whole system, in order to achieve the ideal state that all species can coexist.

So it's better to leave this matter to more professional people to study. Before they come up with a feasible scheme and verify its feasibility, it's better not to mess about.
