Sounds like a better idea to me than a regular coffin in a cemetery, although I personally am going for cremation. http://www.boredpanda.com/biodegradable-burial-pod-memory-forest-capsula-mundi/

In one of my high school history books, I read about a peach orchard somewhere in South Africa that is on the grounds of a Boer War battlefield. The soldiers had picked peaches the day before from another orchard and had loaded up their pockets. They were buried where they fell and the peach pits grew into trees, nourished by the soldiers' bodies.
