Chapter 627: 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. "
