Chapter 622

In the scientific research center, there is a special biological cloning laboratory.

This is what Chen Xin built when he studied the genetic improvement of wolves, and the biggest achievements here are the big wolf dogs that played an important role in the southwest earthquake.

They're all bred here.

However, after breeding enough populations, these dogs were transferred to other places for breeding and training. The research center is only responsible for the follow-up research, as well as the cultivation and improvement of a small number of individuals.

So when Chen Xin came to this lab, most of the incubators in the lab were empty, and only a few of them were hatching new embryos.

"Academician, why are you here?" The researchers who are working see Chen Xin coming and say hello to him.

Chen Xin nodded his head as a response, and then he said, "dome new town says that building an ecosystem requires animals to join the ecosystem, so we need to cultivate new animals here, so I'll come and have a look."

When Chen Xin said this, the researchers nodded: "the city level ecosystem is really inseparable from the participation of animals. When Professor Li studied the eco agricultural system before, he considered that we should cultivate a group of animals to participate in the ecosystem.

However, the result of the calculation at that time was that the scale of the eco agricultural system was not large enough and the number of animals was too small. It was not only difficult to maintain, but also very troublesome and costly to cultivate animals. Therefore, we chose to maintain the eco agricultural system by means of automatic machinery or manual work.

Now it is necessary for animals to participate in the construction of city level ecosystem! "

Hearing what the researchers said, Chen Xin felt his chin and asked him, "I understand the importance of animals in the ecosystem, but it's not impossible without animals, is it?"

In Chen Xin's view, the scale of Dome City is not particularly large. Although it is necessary to build the largest artificial ecosystem in history, with the previous research foundation of ecological agriculture system, it is not impossible to build an ecosystem composed of only plants, and the participation of animals is not particularly necessary.

"Although it can be done, it would be too expensive to maintain the whole ecosystem." Naturally, researchers have considered similar questions, so they replied to Chen Xin: "not only are plants pollinating, but animals themselves are part of the ecological cycle. Without this part, it is not worth the loss to rely on external forces to maintain the operation.

Moreover, the addition of animals can also make the whole ecosystem more complete and stable. After all, we are only imitating nature. Only the ecosystem formed by nature itself is the most stable and perfect. "

Chen Xin can only partially agree with the researchers' remarks.

As a part of the ecosystem, animals can make the whole ecosystem more complete, which is certain. It is right that animals can make the whole ecosystem more stable and not easy to collapse, but the ecosystem formed by nature itself is not stable.

Because with the changes of the natural environment, animals and plants are constantly evolving, and the natural ecosystem itself is not immutable.

Otherwise, there would not have been so many niche changes in the history of natural evolution, which eliminated the old overlord and brought the new race to the top of the food chain.

However, Chen Xin would not say this. After all, he just came to confirm the status of the biology laboratory and whether the follow-up animal breeding work can be carried out here. He did not come to discuss the theory of biological evolution with the researchers.

"How many incubators can we use now?" Chen Xin took a look at the empty incubator around and asked the researchers.

"There are 120 incubators here, only 20 of which are in use at present, and the rest can be used at any time." Naturally, the researchers are very familiar with the situation here, so the answer is just open mouth.

Chen Xin nodded with satisfaction and said to the researchers, "in this case, you should be ready to cultivate animals. As for which animals are needed, I will confirm with the project team of dome new town, and then transfer embryos and gene samples from the national seed bank."

"Good academician, we will be ready." The researcher agreed, and his face was excited. After all, there is nothing to do in the biological laboratory now. It is undoubtedly a happy thing to have a new job.

And researchers can also hear that this is a big research project. After all, human beings have never tried to build a city level ecosystem before, which is of great significance in studying how human beings live in harmony with the natural environment and building ecological balance.

Compared with the ecosphere II experiment built by the Federation in those years, it is undoubtedly too large-scale and more meaningful.

After all, the biosphere experiment No. 2 conducted by the Federation in those years was nothing more than a few scientists and simulated ecological environment. They did not build a complete ecological system, nor did they try to let human beings and ecological environment live together.

Most importantly, their experiment failed completely for various reasons.

As a researcher from the field of biology, he is naturally familiar with this period of history. He sincerely hopes that Yanguo can achieve satisfactory success in this aspect, really build an effective and stable urban ecosystem, and realize the harmonious coexistence of human and environment.

This is an epoch-making research even before the disaster, not to mention that the external ecological environment has been completely extinct and collapsed. Only human beings can reconstruct the ecological system in the greenhouse environment.

If the harmony between human beings and environment can not be achieved, it means that human beings can not rebuild the ecological environment of blue star, which is a great disaster for human beings.

Although the blue star itself does not need human beings to rebuild its ecological environment, the mass extinction of species has occurred on this planet more than once, the death of global animals and plants has occurred more than once, and the natural environment will recover itself, it will take at least several decades or even millions of years.

For the blue star itself, this may be just a flick of a finger, but for human beings, this is a long time scale beyond the whole human development process from the initial evolution to the present civilization.

Human beings can't wait that long. Similarly, human beings can't allow the natural environment to evolve naturally, because no one knows whether human beings can adapt to the natural environment evolved from nature.
