Martin Azua, of Spain, has come up with an eco-friendly way to dispose of your corporeal remains after you die. He is marketing his design as the Bios Urn.
The Bios Urn is a biodegradeable urn made from coconut shell, compacted peat and cellulose. Inside is placed your ashes and a tree seed (which you can swap out for a different variety of tree). The urn is then planted in the ground where the seed can germinate, reincarnating (recycling?) you into a tree. Trees take carbon dioxide out of the atmosphere and “exhale” oxygen: so not only do you nourish the life of a new tree, you also reverse the carbon footprint you left behind.
I think the Bios Urn is a much better alternative than simply spreading your ashes over a favorite place or merely taking up space on a shelf in the home of a loved-one you’ve left behind.
