What does the wandering earth rely on for food?

 

 
The Wandering Earth is undoubtedly the biggest winner of the Spring Festival this year.
The magnificent special effects and brainstorming plot are very attractive
.

But have you noticed a question? How to solve the food problem of billions of people in the underground city?
The whole film is mechanical punk >
.

The ground has been completely frozen, and the temperature can even turn carbon dioxide into dry ice (-78.
5 degrees).
Don't even think about crops, even microorganisms can't move
.

The wandering earth has no light at all, and farming is completely finished
.

Not only that, the freshwater and shallow waters are all frozen, the moon is gone, the tides are gone, there is not enough oxygen in the water, the fishery should have collapsed long ago
.

Although in theory there will be many organisms in the deep ocean, such as the ecosystem near the "submarine chimney" that uses sulfide as an energy source, this system is very fragile and the "yield" will not be too large
.
So what exactly does the dungeon eat?
Wu Jing’s explanation for the meal problem is that we eat steamed buns with earthworms!
How to put it, if this is true, it means that the people in the dungeon may eat the same as us
.

Look, I will give you a good analysis
.
Earthworms are worms in the soil, high in protein and low in fat, and have the potential to be used as human food
.

At present, earthworms are traditional Chinese medicine, called earthworms.
They cannot be used as food under Chinese laws and regulations.
There should be no such obstacle in the age of wandering the earth
.

If earthworms can become an important source of food for dungeons, it means that they have the conditions for large-scale artificial breeding
.

    Can raise earthworms, why not raise chickens, ducks, pigs, cattle, and sheep? What's more, earthworms can also be used as animal feed
.

    In addition, earthworms can convert food waste and organic waste into high-quality fertilizers, creating conditions for underground agriculture
.
 
    More importantly, Wu Jing said that he can eat steamed buns, which shows that the human race talent is still there, and the farming civilization of the dungeon is still there!
    Farming civilization needs light.
With light, you are God, and everything in the world can flourish
.

    There is no sunlight on the wandering earth, so use nuclear energy and geothermal energy to transform it into artificial light sources.
This is certainly not difficult for humans who can build 10,000 super engines
.
 
    Now Dutch scientists use artificial light sources to enhance photosynthesis, allowing wheat to mature for six seasons a year, so the agricultural production potential of underground cities cannot be underestimated
.

    With crops, the food chain has a foundation, from insects to pigs, cattle, and sheep.
There should be everything in the dungeon
.

    With the assistance of earthworms and microorganisms, the circular economy of the underground city may exceed our imagination
.
 
    Of course, human beings tighten their belts and smash the iron to come up with a wandering earth plan.
Are there really so many surplus resources used to engage in underground agriculture?
    If not, is there any solution for the dungeon?
    Yes, in fact, the most economical and environmentally friendly way is to eat microorganisms, such as bacteria and algae
.
 
In the biological world, the lower the level, the higher the efficiency of energy and nutrient conversion
.

    For example, 5 catties of feed can only feed 1 catty of pork, and the same feed can produce more than 3 catties of chicken
.

    The conversion rate of insects is higher than that of chicken, duck and fish, and of course the most primitive microorganisms have the highest conversion rate.

.
 
    Now some algae have become food materials, such as spirulina, chlorella, etc.
Their nutrition is more comprehensive, and there are all that should be there
.
It is not a problem to satisfy human survival .

    NASA has carried out some preliminary studies on future long-range space journeys, including food supplies for astronauts
.

    One of the ideas is to "raise" bacteria, and then use human excrement as the bacteria's nutrition to realize self-circulation
.

    Although these things are definitely not as delicious as the Manchu Feast, when the earth is about to die, it is good to be able to eat bacteria, and what more bicycles are needed!
