Green burial is a simple and natural alternative to resource-intensive contemporary burial or cremation. The deceased is laid to rest in the earth using only biodegradable materials and without a vault or toxic embalming, in a woodland or other natural setting, often with a fieldstone or indigenous plant marking the grave. This practice can be used as a conservation tool, enabling the acquisition, restoration, and stewardship of natural areas. Simple natural burials were prevalent for thousands of years (and still are in many parts of the world, including in traditional Muslim and Jewish burials) before the contemporary funeral industry propagated the standard of expensive and elaborate funerals divorced from natural processes.
