I want to be cremated and have my ashes buried in the soil where a tree is planted. this way I will be "one with the tree" so to speak. not in a reincarnation way, but in a symbolic way where my descendants/family can come to visit me, instead of a cement tomb stone.
if not a tree, something of that nature. know what I mean?
I find it interesting that virtually every person on this thread said they wanted to donate whatever they could. Can you imagine if this was just as common amongst theists? We wouldn't have the horrific organ donor shortages as we do now.
Anyway, at death I would also like to donate whatever organs and body parts are still usable. And while donating the rest to science for med school studies is a good thing, I learned after my mother died that it also means being 'preserved' with all of the chemicals, similar to what is done in preparation for burial.
Likewise, cremation is harder on the environment than one would think.
I am encouraged by the rising popularity of "green" burials, some version of natural decomp, and have expressed a preference for this if available.
More than anything, though, I've told my family I do not want them spending a bunch of money disposing of my remains. Whatever is the least expensive method is fine by me.
