Final answer:
New corpse disposal techniques focus on environmentally friendly methods like cremation and natural burial, diverging from the traditional burial practices that have various environmental impacts.
Step-by-step explanation:
The new technique devised for disposing of corpses includes more environmentally conscious methods such as cremation and natural burial. These modern approaches are intended to mitigate the environmental consequences that come with traditional burials in vaults with headstones.
Historical accounts describe a variety of disposal methods, ranging from bodies being left for scavengers, as in the case of the bandit described by Galen, to ritualistic practices and even using corpses as weapons of biological warfare during sieges.
The study of skeleton remains, like the one referenced by Egeland et al, shows evidence of intentional burials and careful positioning of remains according to cultural beliefs and practices, even in secondary burial procedures.
Moreover, indigenous practices as seen in Sagada, Philippines, where bodies are placed in coffins and hung from cliffs, illustrate the diversity of burial customs throughout history and across cultures.
