Chapter 415 Rebuilding the Ecological Cycle

Therefore, finding a new planet suitable for human habitation and then completing interstellar migration is the most important thing.

Of course, although Liu Xiu also considered Pandora, Eva's consciousness was really not easy to deal with, so naturally he did not regard the Na'vi as Liu Xiu's enemies.

Although the humans on Blue Star are now very strong in terms of technology and other aspects, Liu Xiu still does not want to leave a record of killing intelligent races on other life planets in the history of humans wandering on Blue Star.

After all, the memories and education of his previous life told Liu Xiu that cause and effect should exist.

In fact, in Liu Xiu's vision, the future interstellar society composed mainly of wandering blue planet humans should be a peaceful and stable interstellar society where multiple intelligent life forms can coexist with each other.

Rather than an interstellar empire filled with killing, cruelty and oppression.

After all, Liu Xiuhe didn't want to learn from the Japanese devils who did such evil things for resources. Needless to say, the result of the Japanese devils was natural. After being hit by two nuclear bombs, they successfully became Mi Liang's puppet.

···········
One year after the first greenhouse was built, in 2091, when Liu Xiu was 160 years old, Liu Xiu took Liu Siyue, who had just turned 16, and said to her:
"Okay! Open your eyes! This is what Wandering Blue Star looked like before he became a wanderer. Do you like it?"

Liu Siyue looked at the green grass under her feet, the white sky and the rabbits running on the grass, and smiled happily:

"Dad, is this the surprise you gave me? It's so beautiful and pretty!"

Liu Xiu looked at his daughter Liu Siyue's smile and said with a smile:
"So, do you still think that Wandering Blue Planet is inferior to Pandora? You know, there are no furry little rabbits, puppies, or giant pandas on Pandora!"

What Liu Xiu said was not wrong, because Liu Xiu discovered that there seemed to be no fur-bearing animals on Pandora.

For example, the spotted stream beast and the six-legged heavy armored horse are both hairless creatures, which are completely different from most of the furry creatures on Blue Star.

On the Blue Planet, whether it is a tiger, a lion, or a bird, they all have hair or feathers, so compared to the rough, hairless skin of the creatures on Pandora, Liu Xiu still prefers the furry creatures on the Blue Planet.

With the successful construction of the first 10,000 square kilometers of ecological greenhouse, the residents of the Blue Star Underground City, who had nothing to do, now have something to do.

That's right. With the successful construction of one greenhouse after another, the surface temperature has returned to the 20 to 30 degrees Celsius before the Wandering Blue Planet wandered, although the thick permafrost and ice on the surface have thawed.

But one fact that we have to face is that all the plants on the original surface have been frozen to death. If we want to restore the ecology, we must plant trees and reforest the planet to restore its ecology.

This is naturally a task that is more difficult and requires a much larger amount of work than building an ecological greenhouse.

After all, trees cannot grow in a day. Starting from the small saplings, they need to be watered and fertilized every day. It takes a year of hard work to have the green trees and green grass we have today.

Liu Xiu looked at Liu Siyue who was rolling happily on the lawn and did not stop her. Instead, he smiled and took Qin Huairu's hand and strolled along the river.

That's right, in order to facilitate irrigation, many streams and rivers were dug in the 10,000 square kilometers of ecological greenhouses. Instead of using the method of laying pipes for drip irrigation, after all, since the ecological greenhouse is to simulate the previous ecological environment, it should be as similar as possible.

Of course, although the entire residents of the Wandering Blue Star are now devoted to restoring the ecological environment, the construction speed of ecological greenhouses is not that fast.

The most important reason is actually the seeds. There is no other way. In order to build this 10,000 square kilometers of ecological greenhouse, Liu Xiu has basically invested all the plant seeds he had before and had saved.

Therefore, if you want to plant in other ecological greenhouses, you naturally have to wait until the plants in the first ecological greenhouse mature and have new seeds before you can continue to expand the planting area.

Fortunately, this growth is exponential. For example, after the plants in the first ecological greenhouse are planted, the area of ​​​​ten ecological greenhouses can be planted. Then, when the plants in these ten ecological greenhouses grow to the point of seeding, the number will have increased tenfold.

But another important issue at the moment is the issue of plant flowering and pollination. You should know that in the past, flowering and pollination were completely dependent on bees, butterflies, moths, ladybugs, houseflies, mosquitoes, etc.

But now, the global cold temperature below minus 80 degrees Celsius has directly killed all these insects, although in order to maintain species, Liu Xiu also ordered the breeding of bees in several underground cities.

But there aren’t that many bees in these farms! Therefore, artificial pollination is still needed in the early stages, otherwise it would be impossible for the plants to bloom and then bear fruit.

Of course, this global extinction is not without benefits. For example, insects such as mosquitoes and flies can only be preserved in a few biological laboratories and there is no other place to preserve them.

It's not like bees have special artificial gardens for them to collect nectar.

Therefore, this time the reconstruction of the biosphere of Blue Planet can be done exactly as Liu Xiu wants. For example, Liu Xiu does not plan to keep mosquitoes. Although mosquitoes are also an important member of the ecological cycle, the absence of mosquitoes does not mean that the ecosystem will collapse.

After all, let's take pollination, which is the most important thing for plants. In addition to male mosquitoes, there are other insects such as bees that can complete the pollination of plants!

In addition to mosquitoes, Liu Xiu did not plan to release any more insects like flies. He just wanted to keep some for research in those biological laboratories. As for releasing the flies into the newly built ecological greenhouse, Liu Xiu directly refused.

Although flies play an important role in the ecological environment, for example, in the ecological environment, flies have the ability to decompose substances.

They prefer to find food on garbage piles, feces, carcasses, and other organic matter. By chewing and digesting organic matter, flies break down this waste and convert it into more basic inorganic substances. This process helps reduce the accumulation of waste, thereby maintaining a sanitary and sustainable environment.

Flies also help spread pollen to a certain extent. Flies often appear around flowers and help spread pollen without realizing it. This is especially important for plants that are pollinated by insects. It is precisely because of the help of flies that some plants can achieve pollination and fruiting.

In addition, flies are also important in the food chain. Although they may look small, they are also a key link in the ecosystem. Flies are the main food source for many small animals and creatures. They are considered a delicacy by birds and reptiles, so these animals depend on flies for survival. Without flies, these animals will not be able to survive.

However, these advantages are nothing compared to their disadvantages!

When flies sleep on organic surfaces and forage for food, the bacteria and pathogens on their body surfaces are also spread to the places they touch, so it is necessary to eliminate flies in order to prevent the spread of diseases.
