Okay, we have talked about the lack of oxygen by using “sealer caskets” and the implications of that in “above ground” burials. However, even if you use a wooden/non sealer casket, place in a vault and bury at 6 feet, there is still no oxygen. So it does not matter if you use sealed, or non sealed with a ground burial and vault, or even no vault for that matter….there is no oxygen buried under 6 feet of dirt. Do you still become subject to anaerobic breakdown and smelly stew underground no matter what you are in?
