The Capsula Mundi project ran by Italian designers Anna Citelli and Raoul Bretzel is an alternate way to be buried.
They created “seeds” or burial pods that will hold a deceased human body for burial. The body is in the fetal position within the “seed” and then is buried. A tree is planted over the “seed” and will gather nutrients from it and grow.
The best thing about these types of burials is that your loved ones can visit a field of trees instead of a dreary cemetery.
