The death industry markets caskets and embalming under the rubric of helping bodies look 'natural,' but our current death customs are as natural as training majestic creatures like bears and elephants to dance in cute little outfits, or erecting replicas of the Eiffel Tower and Venetian canals in the middle of the harsh American desert.
Vaults and caskets are not the law; they are the policy of individual cemeteries. Vaults prevent the settling of the dirt around the body, thus making landscaping more uniform and cost effective. As an added bonus, vaults can be customized and sold at a markup. Faux marble? Bronze? Take your pick, family.
Not only is natural burial by far the most ecologically sound way to perish, it doubles down on the fear of fragmentation and loss of control. Making the choice to be naturally buried says, 'Not only am I aware that I'm a helpless, fragmented mass of organic matter, I celebrate it. Vive la decay!'
