There are several ways to return to the earth after you die, and find new life as a tree.
Bios Urn makes a biodegradable urn that transforms you into a tree after you die. For about $145, you can become a Maple, Ash, Gingko, Beech, Ash, or you can use a seed of your choice.
If you choose to have a green burial in a forest, it is likely that your body will become a part of the soil that nourishes the trees.
Sadly, this is only a concept project, but the images are so wonderful we hope that they will inspire more innovation in this area.
