Vita believes that upon our death, the material that comprises our bodies ought to return to the flux so that other living organisms might have the benefit of our minerals. This ought to be done in a manner that does not produce environmental pollution, and preferably enhances an ecosystem.
With respect to cremation, non-fossil fuel energy sources ought to be used so as to not create unnecessary carbon emissions. Similarly, the body ought not to be dressed in synthetic fabrics as these will create unnecessary air pollution. Metals that will enter the flux if cremated ought to be removed, for example mercury based fillings. With respect to the disposal of ashes. If these are returned to the environment, this will facilitate the uptake of the minerals into the biosphere.
Alternatively, they might be retained by loved ones as a way of prolonging the spirit of the deceased.
Some new approaches to burial are interesting such as the Infinity Suit of the Capsula Mundi that fosters the uptake of minerals into a growing tree. Organ transplants and other ways that our bodies can ethically benefit society should be encouraged.
