Bury me beneath a willow

This is pretty neat.

Bios, a biodegradable mortuary urn that contains the seed of a tree. Once the urn is planted, the seed germinates and begins to grow.

I think it'd be neater if they skipped all the burning up valuable nutrients and just planted my dead body under a root ball, like we do with dead fish. Worms are happy, tree is happy, and no CO2 polluting the air. Forests are much nicer than cemeteries if you ask me, not that anybody did.
