Sorry if this topic makes you uncomfortable. This article explains a process on how to do that. Bodies don't break down for awhile even in the soil frequently nowadays, purportedly due to all the preservatives in the food we eat.
Here is a potential solution.
Here is a video of a ted talk by a woman who designed a burial suit inoculated with fungi to help decompose people meat... and other stuff.
I think this is a great idea. Personally I'd like to be tossed into a hot compost pile.
Maybe I'll have something like the following tattooed on my chest:
Once cold, partition accordingly and combine with greens, browns and manure.
Mix well, add water to soften and cover.
Allow to stand 4 days.
Mix on alternating days until cool, adding water if needed. Once no discernible human pieces exist and mixture has even consistency, spread evenly upon food forest floor. Screen for teeth if desired. Ain't no gold in these here teeth so...
