Doomsday Bunker Upgrade

In a dome city, insects are flying all over the sky. They are constantly nibbling on the leaves of the planted plants, making the originally vibrant environment dilapidated and barren.

A large number of insects are rampant, and even other animals are unable to resist such a terrible disaster. The streets are full of dead small animals, and their corpses are also eaten by insects, and even become a breeding ground for new insects.

"It failed again!" Chen Xin couldn't help but heaved a long sigh when he saw this scene, and the researchers around him who saw this scene with him became very depressed.

"Sure enough, it is too difficult to artificially construct a stable ecosystem!" A researcher couldn't help but give up on himself, and almost lost the confidence to continue.

This is the seventeenth time they have failed. Although this time the entire ecosystem lasted longer than any previous test they had done, in the end the entire ecosystem was still due to the gradual death of birds and the almost exponential reproduction of insects. The number leads to the collapse of the entire ecosystem.

Before this, the sixteen attempts they had made also ended in failure.

For the first time, due to the failure to control the species of plants, insects produced toxins after eating plant leaves, which poisoned birds, and the dead bodies of birds caused indirect poisoning of other animals, and the entire ecosystem collapsed.

Although I noticed the problem of plant species the second time, the number of birds in the city was out of balance due to the hunting of pet cats. In the end, you still caused insects to flood and the entire ecosystem collapsed.

The third time was a surge in the number of birds, eating up all the insects; the fourth time was the introduction of predatory birds to maintain balance, resulting in common birds being hunted down due to territorial issues; the fifth time...

Chen Xin flipped through the experiment records, and didn't want to think about how they failed before.

In all seventeen experiments so far, the shortest ecosystem they insisted on lasted only seven months, and the longest was this time. Although it lasted a total of ten years, it eventually collapsed.

"Where is the problem? We have fully considered the needs and output of all animals in the entire food chain, why did it still collapse?" A researcher asked unwillingly, as if he was questioning other people, and also question yourself.

Faced with this problem, Chen Xin sighed helplessly: "The ecological balance itself is very fragile, and any variable may easily break the original balance. It takes a long time for nature to form a stable structure. time to form a stable coexistence relationship.

Our current idea of ​​artificially bringing together several creatures to build a balanced and stable ecosystem...is too idealistic. "

Although Chen Xin didn't think it was impossible, after so many failures, even he had to admit that a truly stable ecological environment was far from being formed by adding a few creatures.

Perhaps there is indeed a natural enemy relationship between two species of organisms, but the impact of population size, environmental carrying capacity and other environmental factors often leads to results that are not as ideal as expected, and the relationship between theoretical results and actual results may often be just The difference in a certain variable will lead to a huge difference.

"Is our thinking wrong?" Although the seventeen consecutive failures made everyone very frustrated, some researchers still put forward new ideas: "Every experiment we have put animals in at one time, As a result, due to the difference in reproduction speed, the development speed of the populations is different. As a result, a balanced ecosystem cannot be formed, and the ecosystem collapses quickly every time.

This time we tried to multiply the population of species to a certain scale and then release them in batches. The entire ecosystem collapsed only after ten years, which lasted longer than before. So should we adjust our thinking? "

"You are right. Ecological balance should be a dynamic balance. There should be a certain degree of flexibility in the number of different populations, so that the entire ecosystem has a certain fault tolerance rate and automatic correction function. Perhaps we should really change Thinking about it." After hearing what the researcher said, Chen Xin couldn't help but nodded in agreement.

Their previous experiments mainly relied on Professor Li's successful experience in studying ecological agriculture systems, combining several coexisting animals and plants according to the consumption and supply relationship in the food chain, thinking that a balanced ecological system can be constructed.

However, it is clear that the ecosystem cannot be formed by a simple combination of several species.

In particular, changes in environmental factors will have an impact on the ecology of species, and there are also mutual influences between different species.

Under such circumstances, there are actually quite a lot of variables that affect the final ecological balance. Although Chen Xin can simulate the impact of various environmental variables here, he cannot calculate a correct answer.

Or there are correct answers, but the conditions they provide are not sufficient to calculate the optimal solution.

Facing the situation in front of us and the failure of seventeen consecutive experiments, it is also a good choice to change our thinking.

"Speaking of which, we seem to have overlooked another important factor!" At this time, a researcher was trying to replay the test just now, but just looking at the replay results, he suddenly discovered a blind spot.

Hearing what the researcher said, Chen Xin looked at him curiously: "What did you find?"

"What we need to build is an urban ecosystem, right? But so far, we seem to have never substituted the city as a variable into the entire ecosystem! And all the time we have only simulated the ecology of animals and plants, It doesn't count the existence of human beings themselves." The researcher said loudly about his discovery.

"It's true to say so, but we can't build a stable ecological system without ignoring cities and human activities. If we add human activities and cities as influencing variables, it may be even more difficult to achieve a balance, right? "Although other researchers agreed with the problems he discovered, they did not agree with his ideas.

Chen Xin had a somewhat different view on this. He interrupted the debate between the two researchers, thought for a while and said: "Since we want to change our thinking, it is also a good idea to add urban variables and human activities to the ecological system as a reference." Road, after all, this is the result we are looking for in the end, it is easier to calculate it now, isn’t it?

And compared to this, what we should consider is how to build this system first so that it can run smoothly, instead of always being destroyed for various reasons like now. "
