Quels sont les avantages de la crémation et existe-t-il un mode d'inhumation respectueux de l'environnement ?
En 2021, il y aura un véritable incident au Guizhou où le corps a été enterré et incinéré. Selon les rapports, le défunt était un vieil homme et son enfant a été incinéré à l'origine, mais le salon funéraire n'est pas arrivé à l'heure, craignant de manquer le moment propice, de sorte que l'enterrement a finalement été organisé. Les autorités locales compétentes ont estimé que l'inhumation du corps du vieil homme violait le système de crémation local, elles ont donc forcé l'ouverture du cercueil et le corps a été transporté au crématorium pour y être incinéré.

Astronomers: Senkaku IV was pierced by a mysterious force before it became dark
Every shining star in the universe will be extinguished one day, and its "lifespan" is closely related to its mass. For example, Proximal is about 12.2% of the Sun's mass, and its "lifetime" can be as high as trillions of years, while the Sun's "lifetime" is only about 10 billion years, and those stars are much larger than the Sun, its "lifetime" is even shorter.
