I'm going green... Told the wife when I go to make it as simple and "green" as possible. No chemicals (embalming). Then have a red apple tree planted on top of me. Invite anyone and everyone over for apples every year. We have a family graveyard so I can get away with it.

The Mushroom Coffin: an Eco-Friendly Option for Burial
The Mushroom Coffin is a new innovation that uses a mixture of fungus as a means to decompose human remains, giving people another option besides cremation.
My cousin told of an American Indian friend of his, who's family really liked dogs.
For several generations they had been burying their deceased pets and planted a fruit tree on the grave. The dog keeps sustaining them. He says they have quite an orchard.
