Once you might have been buried under a tree. Now you can BE the tree. How would you like to grow into a tree after you die? This is a Bios Urn, a completely biodegradable urn that contains a single tree seed. When planted, the tree seed is nourished by and absorbs the nutrients from the ashes. The urn itself is made from coconut shell and contains compacted peat and cellulose. The ashes are mixed with this, and the seed placed inside. Because ashes are a good source of phosphorus, cremated remains serve as good fertilization for trees. You can even choose which type of tree you'd like to grow! So which would you prefer — leaving behind a tree or a tombstone?
