7. Mountains of Silence
Zoroastrians believe the body is impure and shouldn’t pollute the earth after death through burial or cremation. Instead, the deceased are brought to a ceremonial “tower of silence”, usually located on an elevated mountain plateau, and left exposed to the animals and elements. When the bones have been dried and bleached by the sun, they are gathered and dissolved in lime.
6. Tree Burials
Because ground burials are passé, Indigenous tribes in many parts of the world discovered that the best way of disposing the dead was to put them up high. Groups in Australia, British Columbia, the American southwest and Siberia were known to practice tree burial, which involved wrapping the body in a shroud or cloth and placing it in a crook to decompose.
