    However, no matter how much she grapples with regrets in her heart, she is here after all, and it is not her character to give up halfway.

    Therefore, she quickly stabilized her emotions and calmly accepted the current situation.

    Then, open your communicator.

    Start searching for the agricultural history of this world.

    After some screening, Qiao Mu finally found a related paper on the history of agriculture in the modern and contemporary times on a relatively reliable website.

    The name of the paper is¡ª¡ª

    "The Rise and Fall of Agriculture in the Past Thousand Years"

    After reading this paper and checking the dozens of citation articles at the end of this paper, Qiao Mu finally understood how the world¡¯s agriculture became what it is today.

    The reasons are many and complex.

    The agricultural development trend of this world more than 800 years ago was very similar to the development of many civilizations that had just entered the third industrial revolution. Basically, they used pesticides, chemical fertilizers and other substances on a large scale to increase the output of agricultural products. At the same time, pesticides were also used  On the basis of chemical fertilizers, the quality or certain characteristics of agricultural products themselves are constantly improved, so as to increase the production of agricultural products or resist drought.

    Generally speaking, there are many research directions.

    Some are developing in the direction of pest resistance, some are developing in the direction of drought resistance, and some are developing in various aspects such as cold resistance or increasing production, sweetening the taste, enlarging the fruits, etc. It can really be regarded as an era when a hundred flowers bloom, but that is also  An important transition period for the development of entire civilized agriculture.

    Although chemical fertilizers and pesticides can suppress pests and increase yields to a certain extent, they also cause profound damage to the land.

    The soil is hardened, the land is inert to a certain extent, the elements of the land are out of balance, nitrogen and other elements far exceed the original content of the land, etc.

    These land problems will continue to expand and become deeply rooted as the abuse of chemical fertilizers and pesticides continues.

    Eventually it became ingrained.

    The extent to which it is difficult to change.

    At that time, many countries had discovered this problem and made certain changes.

    For example, we can promote organic fertilizers, implement a fallow system, or even directly carry out soil purification and soil modification, as well as promote hydroponic technology.

    ¡°However, these have failed to curb the deterioration of the situation, because the cost of doing so is very high, and many people are simply unwilling to comply.

    Still stick to your original approach.

    If the yield is not enough, increase the amount of fertilizer.

    If there are too many bugs, use more pesticides and so on.

    These have undoubtedly made the quality of the land become worse and worse, and the quality of the various fruits, vegetables and crops produced has also become worse and worse.

    ? If that¡¯s all it is.

    It¡¯s nothing more than a decline in the quality of the food.

    But when these problems occur in agriculture, there are many other things happening in the world, such as energy consumption caused by industrial development, environmental pollution, increased carbon dioxide concentration, reduced oxygen, and strengthened greenhouse effect.

    Iceberg melting and a series of other events.

    " None of these problems is particularly troublesome when taken individually, nor does it sound particularly harmful. However, when these problems are brought together, any accident may cause great damage.

    More than five hundred years ago.

    In the last few years of the third industrial revolution, many single hazards overlapped with each other, creating a special state in which the end of the world was imminent.

    First of all, the greenhouse effect and the El Ni?o phenomenon in those years were extremely serious, which directly led to the extreme weather and extreme disasters in those years reaching a level that is rare in millennia. Floods, earthquakes, volcanic eruptions, wildfires, and even droughts and tsunamis occurred in endlessly around the world.  One after another.

    At the same time, the rise in sea levels caused by the large-scale collapse and melting of glaciers has caused many countries with low sea levels to begin counting down their nations.

    In addition to these natural disasters, ancient viruses that were originally frozen in the North and South Poles are also caused by the collapse and melting of large areas of glaciers.

    Gradually recovered.

    Humans already have a certain degree of resistance to some viruses existing in nature. Even for those viruses that have no resistance, humans basically have corresponding solutions. The few viruses that have no response methods also have certain protective measures.  You won't be in a hurry.

    ¡°But humans are very unfamiliar with ancient viruses, and only a few countries have known about them.There are corresponding professional research institutions, and the professional research institutions in a few countries have not yet begun to study those ancient viruses.

    This led to some active elements of the ancient virus, those with the ability to reproduce and spread relatively quickly, to initiate unprecedented virus expansion and infection, which undoubtedly made things worse for all humans and countries at that time.

    With so many disasters, viruses, extreme weather and other problems added together, even if most areas have pesticides, hydroponic technology, organic fertilizers, etc., they cannot guarantee that the output of various agricultural products will be the same as before, or even if there were  Many agricultural products have been harvested directly.

    In the following years, the situation of various natural disasters has not been improved. In order to cope with those extreme weather, many countries have really had no choice but to abandon their original environmentally friendly behaviors and research such as afforestation, and instead put their research routes to extremes.  Survival in the environment.

    And the agricultural planning that was already moving in the direction of sophistication had to change its research direction again and try to increase the ability and output of agricultural products to cope with various extreme environments.

    There was no way, there were too many extreme environments at that time, agricultural production was also greatly damaged, and the output was simply not enough for everyone. They had no way to pursue the delicious taste of food and could only try their best.  Cultivate various crops in the direction of yield.

    If the situation is not very urgent, then they may still pay a little attention to the taste of the crops themselves while cultivating the crops in the direction of high yields. However, time is really tight at that time, and there may be more after a few months.  Tens of millions of people starved to death, so researchers at the time had no choice but to completely give up on the issue of taste.

    ??Just develop in the general direction of production.

    However, these actions of theirs, whether they are developing technologies to deal with extreme weather or cultivating crops for high yields, are essentially ineffective in restoring the environment, and may even exacerbate the environmental degradation of the planet to a certain extent, and then  This has formed a serious vicious cycle. The more they try to cope with environmental extremes, the more extreme the environment becomes.

    The research on agricultural products is similar.

    Even though the output has been increasing, the area of ??land suitable for planting has become smaller and smaller. In the end, they had no choice but to take out their past food replacement solutions. After a period of research, they came up with a seed  Products that maximize the use of existing agricultural products.

    That is the current nutrient solution.  (Remember the website address: www.hlnovel.com
