Why is it said that nutrient solution can utilize agricultural products to the greatest extent? It is because there are so many raw materials for making nutrient solution and they are very wide.
Tree roots, leaves, potato peels, bark, vines, sweet potato peels, poisonous, non-toxic, edible and inedible, anything that contains essential elements for the human body can be used as nutritional ingredients.
Say something disgusting.
? Human excrement can be used as raw material.
Because the essence of nutritional supplements is to combine the necessary substances for the human body every day for people to eat.
Necessary substances for the human body exist in many things in nature. Regardless of whether they are insects, animals or plant poisons, there are more or less essential elements for the human body. Things such as calcium, iron, zinc, selenium and vitamins are not only available to humans. There are hidden things in the food that many people cannot eat at all.
The production process is nothing more than extracting the ingredients needed by the human body from those edible and inedible things, or directly synthesizing the nutrients necessary for the human body, and then mixing them in a certain proportion. As for the taste, you can't force it. It was almost done at that time. Starving to death, who cares?
That is the original form of nutritional supplements.
Although there were slight improvements later, it was only the addition of some previously unknown trace elements, and there was no major change in essence.
With the introduction of nutritional supplements, humans during the great cataclysm more than five hundred years ago were able to barely regain their basic food and clothing, and focused on the research and development of various technologies in other areas.
Complete artificial intelligence technology, the development of industrial intelligent mechanization, submarine survival bases, spacecraft and other technologies were all developed in that era. The fourth industrial revolution also began to sprout from that time and gradually developed.
Sometimes we have to admit that crises and external oppression can indeed promote the progress of human civilization.
The emergence and improvement of complete artificial intelligence technology and industrial intelligent mechanization development technology were mainly due to the fact that the extreme weather at that time was beyond the range of the human body, but we could not just stay in a closed room and turn on the air conditioner and floor heating without working. , just spend the summer and winter.
So the situation at that time was that someone had to go out and work in an environment of more than 60 degrees below zero, more than 70 degrees, or more than 50 degrees above zero. This was undoubtedly a desperate effort.
It can even be described as dying generously.
There are indeed such heroes, such heroes who are willing to sacrifice for the sake of mankind, but there are only so many. You can't sacrifice them all. What a waste of sacrifice for the future. Therefore, using machinery to complete human outdoor work has become A research topic that was at the forefront at the time.
Fortunately, humans at that time had already studied related technologies. The reason why they did not conduct in-depth research and practical applications was mainly because they were worried that if they did so, a large number of people would be unemployed, and the social order might be disrupted.
Later, the world entered a period of great catastrophe.
They no longer have such worries.
Relevant technologies will naturally have to be brought out.
And quickly carry out research and application.
With the continuous breakthroughs in technology, mankind at that time finally managed to regain a certain order during the cataclysm. Except for the overall living standards and population, which had experienced a qualitative decline compared with the past, other aspects were fine.
Things have developed to this point.
Especially when those spacecrafts that went out to explore had not yet found any planet suitable for human survival or life-changing planets suitable for human transformation and survival, restoring the environment of their home planet became the top priority at that time.
After a period of discussion, all countries quickly formed a loosely united community and began to do their best to repair the planet.
At that time, we were really cruel, and all countries stopped all behaviors that were harmful to the environment.
Most of the energy and ability of the entire human race were devoted to afforestation and environmental restoration. However, even so, it took more than a hundred years for humans at that time to barely save the planet from extreme weather. The overall environment has returned to the state before the disaster.
When it reaches this level.
The coalition government at that time still did not stop the policy of protecting the environment, and even set 80% greening as the bottom line, which must not be wavered.
It¡¯s been done this way for hundreds of years.
The current situation here is that the forest area is very large, and the urban green area is also very large.
Only the planting area is extremely scarce.
The only thing on this planet now is??Among the arable land that occupies less than 5% of the land area, more than 90% of the land is used to grow several crops with extremely high yields, extremely poor taste, and necessary for making nutrients. Only less than 10% remains. The land can be used to grow ancient crops.
With the same planting area.
The yield of crops grown specifically for nutrient supplements is more than a hundred times that of ancient crops.
So generally speaking, the output of ancient crops is naturally relatively scarce, and it is normal for the prices to be high. As the prices of ancient crops rise, the prices of ancient animals raised with ancient crops will naturally also gradually rise, as well as the price of seafood. Relatively cheap.
The elements contained in meat in nutritional supplements.
Most of them come from seafood.
As for why not just grow ancient crops?
??While maintaining the bottom line of maintaining a forest coverage rate of more than 80%.
It would be so easy to feed a population of nearly 30 billion on less than 5% of the total arable land, if all the currently usable arable land were used to grow those ancient crops.
That would starve to death more than 25 billion people.
Only then can we barely feed the remaining people.
So in summary, until they find another living planet, or an agricultural planet that can grow crops on a large scale, it will be difficult to shake the agricultural production situation here.
"Forests cannot be destroyed, and there is no way to increase the area of ??cultivated land, so why not consider hydroponic technology and space planting more? Hydroponic technology does not occupy much cultivated land. Some civilizations have already developed it in the middle and late stages of the third industrial revolution. It¡¯s planted in space, but there¡¯s nothing here¡¡±
After understanding the specific situation, Qiao Mu only complained a few words, and her flexible little brain roughly guessed why they didn't do what she thought. According to her estimation, they were probably because of hundreds of years of nutritional supplements. I'm used to it now, and I don't think about it at all.
And those who are able to do so, the money in their hands is enough for them to eat crops every day, and those who are unable to do so are useless just thinking about it.
As for planting in space or something like that.
It is estimated that there should be some, but the senior management here has not thought about promoting them at all, and they have planted them in large quantities and transported them below to sell them at low prices. Moreover, the cost of planting in space is not low. If they are promoted, they may not be as easy to sell as normal ancient crops.
Why bother with that?
What do the people want now that they have enough food and clothing? (Remember the website address: www.hlnovel.com
