"Natural burial
A growing trend in modern burial is the concept of natural burial. Popularised in the United Kingdom in the late 1990s, natural burial is being adopted in the United States as a method for protecting and restoring the natural environment.
With a natural burial, the body is returned to nature in a biodegradable coffin or shroud. Native vegetation (often a memorial tree) is planted over or near the grave in place of a conventional cemetery monument. The resulting green space establishes a living memorial and forms a protected wildlife preserve.
Natural burial grounds are also known as woodland cemeteries, eco-cemeteries, memorial nature preserves, or green burial grounds."

"In Orthodox Judaism embalming is not permitted, and the coffins are constructed so that the body will be returned to the Earth as soon as possible. Such coffins are made of wood, and have no metal parts at all. Wooden pegs are used in the place of nails. Followers of the Islamic faith also prefer to bury their deceased so as not to delay decomposition. Normally, instead of using coffins the deceased are buried in a shroud, and the bodies of the deceased are not normally embalmed. "
from what i understand , 'natural' burials are perfectly acceptable - except in cases of of communicable diseases - , of course , the undertaker would likely have a different opinion .
how the heck did we get into this
