In one of my first English classes in college, we read a paper on the embalming process.
This is the worst way to "honor" the dead person, since they suck out the fluids, stuff with padding and preservatives, sew the mouth closed (and eyes sometimes), it's really gross and an insult to the dead.
*Now in the case of an autopsy, that is different if it is deemed necessary to find out why the person died or who killed them.
I originally wanted to be cremated because it's so much cheaper and less disturbing. (only $900 in my state)
However, recently I heard about the "Natural Burial" movement in the US (currently not allowed in my state).
Natural burials are just that, a hole is dug in the woods, the persons (Non-embalmbed) body is placed in the hole with a fabric cover and then the person is buried as usual (I think they don't bury quite as far down as in normal burials). The person's body naturally decomposes into the ground, just like people used to be buried!
Embalming fluids are highly toxic, and end up leaching through the coffin/cement casing and into the ground water.
Also, embalmed bodies do NOT decompose properly. It's just a really disgusting process.
