Introduction: Where do the lice go?
In China in the 70s, lice became a small parasite in almost every household.
It is not an exaggeration to say that everyone had lice in those days, and even in the casual conversation after home-cooked meals, some people often ridiculed the lice on their bodies for being too many and fat.
Nowadays, it is almost impossible to hear about lice on anyone, and even when you hear some people say that they feel like lice when they wash their hair or take a shower, it sounds like a joke, because people don't seem to remember lice anymore.
People can't help but wonder: where have the lice that everyone had decades ago go in today's society?
Could it be that lice have gradually evolved and disappeared with humans?
So what kind of parasite are lice?
What kind of relationship does it have with human beings in our lives?
What kind of parasite are lice?
There is a reason why lice were able to be closely related to human life thousands of years ago.
First of all, to understand lice, it is necessary to understand the characteristics of such a parasite.
Lice can be considered a very tenacious parasite, and although they look disgusting, they show an extremely strong ability to survive in harsh environments.
It can survive in polar day and night environments, and reproduce thousands of offspring.
In extremely high temperatures, the permissible temperature can be as high as 70 degrees, and in extremely low environments, lice can even survive in minus 20 degrees.
Such tenacious creatures would have thrived on Earth tens of thousands of years ago, and at one time stored large amounts of energy and survivability.
For such creatures, we can't help but ask: why can they survive and reproduce for tens of thousands of years?
In fact, this creature is closely related to the life of humans, and it can even be said that they are parasitic on humans, therefore, for their survival, the survival of humans is crucial.
And this creature is also extremely adaptable, able to adapt to extremely high and very low temperatures.
At the same time, in the environment in which humans live, they are able to quickly detect humans and quickly parasitize humans as hosts.
That's right, lice are such a tenacious parasite that is closely related to human life.
When humans leave their original living environment, lice will quickly find a new host to thrive in the new environment.
Therefore, the presence of lice in life is very high, and people will even start a wonderful symbiotic relationship with lice, and they will live in mutual benefit and symbiosis with each other.
The rise and fall of lice and human life.
In fact, lice do not actively provoke humans, but they can smell the scent of humans and find their existence.
At the same time, lice can also spread through the air.
This is the embodiment of the delicate relationship between humans and lice.
Humans may not actively look for lice in their lives, but once they perceive the presence of lice, they will feel extremely nauseous and feel that their limbs have no strength.
As a result, humans have tried their best to expel lice from their lives.
However, lice are able to absorb nutrients through the skin in the bloodstream.
At the same time, they are also able to live and reproduce on the host's body.
This is the relationship between lice and humans.
With the development of society, the living conditions of human beings have gradually improved.
However, lice, as a parasite, are closely related to human life.
Human hygiene is poor and living conditions are poor, which is more conducive to the survival and reproduction of lice.
However, when human hygiene gradually improved, the number of lice gradually decreased.
In human life, because lice do not take the initiative to provoke humans, humans gradually feel numb to the existence of lice.
With the gradual increase in human hygiene awareness, people have gradually become aware of the harm caused by lice to the body.
There are even some specific professionals who will sanitize the body from time to time to ensure that there is no lice parasitism.
As human hygiene awareness continues to increase, the number of lice is gradually decreasing.
With the development of society, people's living conditions have gradually improved, and the population of lice has gradually decreased.
Nowadays, lice have basically become an after-dinner joke and a topic of ridicule among people.
Where do the lice go?
So, where do lice go?
In fact, lice don't go away completely.
They may be present in other forms in the ecosystem.
After all, an ecosystem is an extremely complex system, teeming with a variety of organisms that are closely linked to each other.
And lice, as a part of it, also have their special significance in their existence.
Although lice may no longer be important in human life, they still play an important role in the ecosystem.
For example, they may be food for certain birds, or hosts for certain parasitic plants.
The way of life of humans is constantly changing, which also means that the environment in which lice live is also changing.
With the migration of humans and the process of conquest of nature, the living environment of lice is also constantly changing.
As a result, the distribution of lice also changes.
In some subsurface, lice are still an integral part of human life.
For example, in some remote areas, the number of lice is relatively high due to the poor living conditions of people and relatively poor sanitation.
In addition, in some developing regions, lice populations remain high due to a lack of sanitation.
People in these areas still live in the same space as lice, and lice also become a part of their lives.
As a result, lice have not really disappeared, but are constantly changing with the way of life and the development of society.
epilogue
Lice don't go away, but their presence changes with the way humans live.
In modern society, lice are in a declining number but not disappearing, and they may continue to exist in the form of other organisms.
As the ecosystem changes and the way of life of humans changes, the status of lice will also change with the changes in human life.
Therefore, the relationship between the existence of lice and humans is still close.
While pursuing a better life, human beings should also pay attention to ecological balance.
Lice are small, but they are part of nature, and their presence has its own unique significance.
Increasing human hygiene awareness is key to eradicating lice, but at the same time maintaining ecological balance.
The fate of lice is closely related to humans, and their existence is a gift from nature and a link between humans and nature.
