We should just go back to burying people in the ground, and let nature take its course. I mean bury them in untreated lumber coffins -- none of these expensive, glossy luxury coffins with anti-bacterial liners and whatnot.
When you embalm corpses and put them in a hermetically sealed coffin with anti-bacterial liners -- you should see what happens. The body turns to goo.
Better to let nature take its course. Just bury the body 6 feet under. "For dust thou art, and unto dust thou shalt return."
If you love and miss your deceased loved one, then pray for his soul. He's not going to live forever just because you kept him "safe from the worms". No, he's just going to liquefy instead. And I'll let you guess the nature of that liquid. Decomposed protein, anaerobic decomposition. Basically diarrhea. How is that any better?
When I'm dead, please just let the worms clean my skeleton. And pray for my soul. And all the money normally spent on expensive caskets and liners? Fill the hands of the priests to offer Masses for my soul.
