Due to the implementation of cremation in recent years, people everywhere, especially in the countryside, have become more and more fierce in the debate on burial and cremation, and most people still hope that they can lie in the coffin after death and burrow into the ground, but experts "do not allow", because experts believe that there are still more drawbacks to burial.
First, waste of wood, burial must first put the deceased in the coffin, and then can be buried, and compared to the cremation of a small urn, the coffin used in the burial needs to use much more wood, and the urn in addition to the use of wood can also use other materials, and the coffin can only be wood in most cases. In addition, coffins are made of old trees that are decades or even half of the year, which is a very large waste of wood, which is contrary to the current concept of protecting the environment.
Second, waste of land, cremation will basically bury the ashes in a fixed cemetery, the required cemetery area is not large. Due to the need for larger cemeteries, many places can only set up cemeteries in cultivated fields due to lack of vacant land, resulting in waste of land.
Third, pollute the environment, some people die naturally aging, some people are infected with infectious diseases, if buried, without high temperature treatment of these bacteria or viruses may follow the rain from the coffin to pollute the environment or water sources, resulting in the spread of disease.
Taking into account the following points, cremation is currently being vigorously promoted throughout the country, and farmers are basically not allowed to carry out burials. But experts say that burial has drawbacks, farmers believe that cremation also has drawbacks, cremation is to use flames to cremate people, and in the cremation process, whether it is electricity or coal, it needs to use a lot of energy, which also has drawbacks in the current energy shortage. And in the process of incineration will also produce harmful gases such as sulfur dioxide, according to statistics, a 120-pound corpse will have 0.65-0.7 kg of solid particles emitted into the air during the incineration process, incomplete statistics of China's 1500 crematoriums annual emissions of dioxins to the atmosphere of 30.8-31.3 million tons. Moreover, some areas are affected by traditional concepts, although the body is cremated, but finally put into the coffin for burial, the disadvantages of waste of wood and waste of land have not been avoided, but have aggravated air pollution.
Over the years, the debate over which is better in rural cremation or burial has not stopped, and the current proportion of cremation in China is about 53%, which is significantly higher than the 26% of the United States, but far lower than 90% in Japan. In the future, cremation and burial may not be disputed, because South Korea has invented the latest funerary technology, and the use of this technology can "return the soil to the soil and dust to the dust" in a year.
This latest funerary technology is the "ice burial" technology, ice burial technology as early as 2011, South Korean funeral guidance professor Zhang Wanshi in Wuhan funeral industry exchanges have mentioned, ice burial technology is a simple understanding is to change the current use of high temperature treatment of corpses to low temperature treatment of corpses. The specific processing steps are as follows:
1. First put the body in a freezer at -18 ° C for frozen pretreatment;
2, the frozen body into -196 ° C liquid nitrogen, and this is also the most critical step of ice burial, the use of liquid nitrogen ultra-low temperature to simply treat the body;
3. Use an oscillator to shake the crisp corpse and shatter the body into granules;
4, the granular corpse fragments for water evaporation, so that the human flesh can basically be processed clean, the remaining powder is like "ashes".
5, the last remaining ashes of ice burial treatment is not put into the ordinary urn, but into the organic urn processed from Shuli powder or potato flour, and this organic urn will gradually be decomposed by microorganisms after being buried in the ground, and the ashes will also disappear with the disappearance of the urn in half a year to a year and "dust to dust, soil to the soil".
Compared with cremation and burial, the advantages of ice burial are very obvious, first of all, the liquid nitrogen used in ice burial is separated from the air, and entering the air after use will not pollute the air. The last ashes of the ice burial will enter nature with the urn turning into dust, and will not cause harm to nature, and it can even be said that all the materials used in the ice burial are derived from nature, and finally return to nature, which not only represents a reincarnation of people, but also represents a reincarnation of natural substances, which is very in line with the willingness of the people of our country to believe in "falling leaves and returning to the roots". As for the fear that cremation can kill bacterial viruses, can low temperatures work? In fact, minus 196 ° C can also kill all bacteria and viruses.
That is to say, ice burial can indeed solve the current problem of cremation and burial. It's just that compared to earth burial and cremation, the cost of ice burial is higher, and there is no large-scale promotion in the world at present, but it was introduced by South Korea after being invented by Swedish scientists, and China has not heard of ice burial places. I think that even if ice burial is promoted in the future, it will encounter the same problems as the current promotion of cremation, after all, burial in the history of Thousands of years in China, it is still difficult to change. Whether it is ice burial, cremation, or earth burial, the most important thing is to give people a few more choices, this is also a form of human rights, readers and friends you say?
