How much do you know about the various burial methods after human death?
In fact, as tomb feng shui became famous through various online novels, various burial methods such as sky burial, water burial, tower burial and wooden burial have become known to more and more people, but in fact, in comparison , people are more familiar with the two methods of burial and cremation.
After all, these two methods not only have a long history, but also affect a vast area.
However, what people did not expect is that in modern society, there is a voice of doubt that human cremation is too wasteful.
All living things will undergo ecological cycles after death. If humans choose to be cremated, they are breaking the laws of nature.
So what is the basis for the waste of human cremation? Next, let us think about this issue together and see what is going on.
Mysterious Sky Burial
Ecological Cycle
Ecological Cycle actually refers to the recycling of inorganic compounds and simple substances in the ecosystem.
Under normal circumstances, this material cycle can be summarized by the two concepts of "library" and "circulation" .
The library is composed of a certain amount of certain compounds that exist in certain biological or non-biological components of the ecosystem.
For a certain element, there are one or more main reservoirs.
If you look at it from a certain perspective, all matter will turn into "nothingness" , and then be reborn from nothingness.
The new grass
With the development and progress of human civilization, when microorganisms were discovered by scientists, the matter of decay became no longer a big deal.
Scientists know that this is not a strange phenomenon, but the most important link in the biological cycle.
Like the ancient Chinese saying "Falling red is not a heartless thing, it turns into spring mud to protect flowers", which actually expresses this idea.
It’s just that compared to realistic scientific principles, literati prefer elegant artistic conceptions and colorful visions.

In fact, after a certain stage of death, all living things on the earth will eventually decay and decompose one by one before entering the next round, and we humans are no exception.
It is just because of the birth and growth of civilization that after choosing various burial methods, human beings took the initiative to change the process of the cycle and skipped the most critical link.
Of course, the jump here does not really skip the matter of decay and conversion into energy.
But some scientists believe that after experiencing various burial methods (except sky burial), the energy that humans should have reabsorbed by nature has not been completely absorbed by nature.
Decomposition and transformation of soil
Especially in modern society, in order to save more land resources and promote green environmental protection, it is now generally advocated to choose cremation after people die.
is regarded by these scientists as a waste of resources and breaking the biological cycle. Why is this?
According to
Regarding this issue, we must start with the various components of the human body.
As far as the constitution of a normal adult is concerned, water accounts for 70%, organic matter accounts for 25%, and the remaining 5% is protein, calcium and other trace elements .
When we were young, most of us could not imagine the proportion of water in the human body, but after understanding the "ubiquitous" nature of water, we gradually understood this.
The proportion of human body water in various age groups
In the process of human growth, the conversion rate we should follow and the conversion rate we actually use are actually completely unequal.
This is easy to understand: we absorb energy from nature, but in the end it is not completely converted into energy that can be fed back to nature.
A large amount of energy is consumed in human growth and daily consumption. Therefore, we use energy, but to some extent reduce the total amount of natural energy.
When the human body dies and is cremated, the water evaporates into water vapor. There will not be much loss, but a large amount of organic matter in the human body will be wasted.
The crematorium at work
In addition, the scientists also specially provided data to prove it.
In terms of the proportion of organic matter in the body of normal men and women, men account for 25% fat, women account for 35% fat, and protein accounts for 16.7%.
If all these organic matter are burned, then an adult weighing 60kg will eventually contain a total energy of up to 628008000J, which is almost equivalent to 11kg of gasoline or nearly 50kg of TNT.
Just imagine, the energy of every person walking on the street is associated with such a large amount of mobile TNT. This is too amazing.
TNT explosion effect
However, TNT of this weight looks very amazing, but what we need to understand is that the reason why TNT can produce huge explosion power is mainly due to the extremely high explosion speed of and its own mass. Relationship.
In comparison, the usable energy of TNT of the same quality is actually far inferior to that of oil or natural gas of the same quality.
However, it can also be seen from here that if you choose to directly cremate the human body, it is equivalent to directly dissipating such energy of TNT energy. This is another waste of natural energy.
It is precisely because of this that some scientists are thinking about whether there are better ways to utilize energy in the human body besides cremation.
Scientists conducting experiments
change
In fact, regarding the further utilization of energy, countries around the world have thought of various ways.
First of all, as early as 2004, a funeral company in Sweden proposed the service of freezing .

The specific content is to quickly freeze the human body at minus 18℃ and then immerse it in liquid nitrogen at minus 196℃. In this way, only ultrasonic waves are needed to crush the body.
After the water is finally removed and dried by vacuum, the remaining substances are only organic matter and some inorganic matter.
In fact, in a sense, this is the same as cremation, except that in the process of cremation, a large amount of energy will be consumed, while ice burial will not damage the body's limited energy. any impact.

Secondly, Washington State in the United States has also proposed a law called "compost burial" . The specific technology refers to allowing the human body to be transformed into vegetation in just one month. Fertilizer available.
But in fact, compared with the natural state, this technology only speeds up the entire change process and the efficiency of utilization.
Therefore, the number of people who can accept it is actually not that many.

Of course, in modern society, no matter which method is chosen, it is the free choice that people should have.
The reason why cremation was advocated was to save land and try not to waste large areas of land resources on the construction of cemeteries.
So, considering the various burial methods nowadays, how should we choose?
Choose
In fact, "Be buried in peace" has always been the traditional concept of many Chinese people, and burial has always been the mainstream form of our Chinese nation.
Especially as early as the Warring States Period , "Zhou Rites" mentioned: "all living beings must die, and those who die must return to their homeland."

Since that time, the funeral culture of later generations has been deeply affected. Although there have been special changes in some areas, the core "rest of the deceased" has not changed in essence.
With the passage of time, in modern society, cremation began to be gradually advocated.
After it was actually implemented, we discovered that in fact, in rural areas of our country, cremation did not really save cultivated land, and scientific burial did not completely waste cultivated land.

It is completely wrong to make decisions without understanding the true development process of the matter and the actual results achieved after the implementation of the matter.
Just like when dealing with any problem, compared to looking for the most perfect solution, the most suitable solution is actually easier to find.
Therefore, different burial methods can be promoted, but they must not be forced.
Whether it was burial, which was once considered to occupy more cultivated land, or cremation, which is now gradually considered to be a waste of energy, you can choose to improve it, but you do not have to abandon it completely.
Reasonably planned and designed cemeteries
For countries around the world, the best way to deal with it is to choose actual funeral plans based on the actual national conditions, customs and culture, geographical environment of the country, and the actual conditions of different regions in the country.
Only in this way can the deceased truly rest in peace.
