I saw a video of a sky burial being shared. It shows a skeleton that has been eaten by vultures and is being cut up and given back to the lizards. This sky burial method is famous because it is still there. That work has survived in Tibbatha and some parts of Mongolia. The tradition of sky burial comes to this region from Vajrayana Buddhism. In Vajrayana, the body basket is seen as a vessel to travel between different stages of samsara. After the soul leaves, it is of no use.. it is cut into pieces and fed to animals. That sky burial thing in Vajrayana will come a little later. That tradition was used in much older religions and philosophies than Vajrayana and early Buddhism. Meanwhile, Zoroastrianism, which is one of the oldest religions in the world, had the worst sky burial. Zoroastrianism was practiced by ancient Persians. After the invasion of Islam, those who believed in Zoroastrian religion (Pasi) migrated from Persia. Most of them come to Gujarat. Small groups also come to Sri Lanka. Even now, a handful of Pasi people live in Sri Lanka. A famous political name is Choksi. Choksila also belongs to that moss community in Sri Lanka.
Coming back to the story, the Pasi people continued to carry out minimal sky burials in India. There are also vultures in India that eat these dead bodies. Why is the vulture central to this? The reason is that the vulture is a species of bird that is highly adapted to digging manure. Vultures' stomach acids are extremely strong. Even bones can be dissolved. Its pH value is less than 1. You can imagine the acidity. Apart from digesting hard things like bones, this also does another secondary thing. That is the destruction of bacteria that are ingested during composting. Now, according to the Sorestrian tradition of India, Diclofenac medicine is used for a disease that occurs in cattle in India in the first half of the decade. Along with this, the dead cows are eaten by vultures. It causes the vultures' kidneys to fail and die. About 90% of India's vultures are going extinct due to this hoarding of companions. The side effect of that is that the Zoroastrian sky burial tradition can no longer be continued in India. There is no other scavenger to take the place of the vultures that eat a discarded carcass within an hour or two. Today, the Zoroastrians in India are out of the sky burial tradition for this reason.
As I am very interested in the sky burial tradition (personally my favorite way to go), I heard that the Pasi community in Sri Lanka also did it when I was looking for it. But I don't know any details beyond that. There are many questions left. How did it happen because there were no vultures in Sri Lanka (except for Vagrant Recordings) who had that tradition.
