Unfortunately, my final resting desires are probably illegal.
After harvesting any organs that may be useful, I would want my body to be dumped in the middle of a huge forest. To be assimilated back into nature.
My body could feed countless animals, bacteria, and in the end help feed the forest itself. I am a part of nature. Nature has a system of "recycling".
I find the idea of pumping my body full of chemicals and locking it in an airtight box so only the anaerobic bacteria can feed on me to be abhorrent.
Cremation is a lot cleaner, and what I will probably be forced to do, but at the same time a waste of nutrients. Soylent Green jokes aside, there is much in nature that could benefit from a body that I no longer have a use for.
