Chapter 524: Failed experiment

In a dome city, insects are flying all over the sky, they are constantly gnawing on the leaves of planted plants, making the originally full of vitality environment broken and barren.
A large number of insects are raging, and even other animals are unable to withstand such a terrible disaster. The streets are full of dead animals, and their carcasses are also eaten by insects, and even become hotbeds for hatching new insects.
"Failed again!" Chen Xin who saw this scene couldn't help but sighed, and the researchers beside him who saw this scene with him became very frustrated.
"Sure enough, it is too difficult to artificially build a stable ecosystem!" A researcher couldn't help but abandon himself a little, almost losing the confidence to continue.
This is the seventeenth time they have failed. Although this time the entire ecosystem persisted longer than any test they had done before, in the end the entire ecosystem was still due to the gradual death of birds and the almost exponential reproduction of insects. The number has led to the collapse of the entire ecosystem.
Before that, the sixteen attempts they had made also ended in failure.
For the first time, the failure to control the types of plants caused insects to eat plant leaves to produce toxins that poisoned the birds, and the carcasses of the birds caused indirect poisoning of other animals, and the entire ecosystem collapsed.
Although the problem of plant species was noticed 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 that the number of birds surged and ate up all the insects; the fourth time was that predatory birds were placed in order to maintain balance. As a result, ordinary birds were hunted down due to territorial issues; the fifth time...
Chen Xinfan looked at the experimental record and no longer wanted to think about how he failed before.
In all the current seventeen trials, they insisted that the shortest ecosystem only lasted for seven months, and the longest was this time. Although it lasted for 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 would it still collapse?" A researcher asked unwillingly, as if he was asking other people, and also at the same time. Question yourself.
Faced with this problem, Chen Xin sighed helplessly: "The ecological balance itself is very fragile. Any variable can easily break the original balance. It takes a long time for the natural world to form a stable structure. Time to form a stable coexistence relationship.
Our current idea of ​​artificially combining several kinds of organisms together to build a balanced and stable ecosystem... It is too idealistic. "
Although Chen Xin doesn't think this is impossible, after so many failures, even he must admit that a truly stable ecological environment is far from being constituted by the addition of a few organisms.
Perhaps there is a natural enemy relationship between certain two 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. The theoretical results and actual results may often be just The difference of a certain point of variable will lead to the difference of the world.
"Did we have the wrong idea?" Although the 17 consecutive failures made everyone very frustrated, some researchers still put forward new ideas: "Each of our previous experiments put animals in at once. As a result, because of the different reproduction speeds, the development speeds of the populations are different. As a result, a balanced ecosystem cannot be formed, and the ecosystem quickly collapses every time.
This time we tried to multiply the species population to a certain size and then put it in batches. The entire ecosystem collapsed only ten years ago. It lasted longer than each time before. So should we adjust our thinking? "
"Your statement makes sense. The 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. Maybe we should indeed change. I'm thinking about it." Chen Xin nodded in agreement after hearing the researcher's words.
Their previous experiments were mainly based on Professor Li's successful experience in studying the ecological agriculture system, combining several coexisting animals and plants according to the consumption and supply relationship in the food chain, thinking that a balanced ecological system could be constructed.
However, it is clear that the ecosystem is not so simple as a combination of several species.
In particular, changes in environmental factors have an impact on the ecology of species, and different species also have a mutual influence relationship.
Under such circumstances, there are actually quite a few 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.
In other words, there are correct answers, but the conditions they provide are not sufficient to calculate the optimal solution.
In the face of this situation and 17 consecutive failed experiments, it is also a good choice to change my mind.
"Speaking of speaking, we seem to have overlooked another important factor!" At this time, a researcher was trying to replay the test just now, but looking at the results of the replay, he suddenly discovered a blind spot.
Hearing this researcher's words, 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 we have been simulating all the time. There is only the ecology of animals and plants, and there is no calculation of the existence of human beings." The researcher said aloud his findings.
"That's right, but we can't build a stable ecosystem without ignoring cities and human activities. If we add human activities and cities as the influencing variables, it might be 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 slightly different view on this. He interrupted the argument between the two researchers and said after thinking about it: "Since we want to change our minds, it is also a good idea to incorporate urban variables and human activities into the ecosystem as a reference. The way, after all, this is the result we finally seek, and now it’s better to bring it in, isn’t it?
And more than this, what we should consider is how to build this system first so that it can run smoothly, instead of being destroyed for various reasons as it is now. "
