Vulture shortage threatens Zoroastrian burial rites
A steep decline in vulture populations, driven largely by veterinary drugs like diclofenac and other human-caused poisoning, is undermining traditional Zoroastrian “sky burial” rites that depend on these scavengers to dispose of human remains. Commenters weigh the ecological consequences of losing vultures—key carcass cleaners and apex scavengers—against the pressure on religious and cultural practices to adapt, noting that some Zoroastrian communities have already shifted to alternative burial methods. The exchange also touches on broader themes of how cultures change under environmental stress, the ethics of preserving traditions that rely on fragile species, and parallels with other evolving burial practices such as human composting.
Podcasts and Background Resources
- Several commenters recommend podcast episodes on Towers of Silence / Zoroastrian sky burials, particularly one from Radiolab, praised as clear, well-structured, and with a satisfying resolution.
- A 99% Invisible episode is also mentioned but described as less focused.
Culture, Tradition, and Change
- Strong debate around whether “our culture is dying” is a meaningful concern or mostly entitlement to past practices.
- Some argue traditions and religious rites are important intangible values that connect past and future, not just “practicalities.”
- Others criticize attempts to freeze cultures in time (e.g., indigenous hunting of endangered species justified as “tradition”) and argue healthy cultures would evolve.
- There’s pushback against overly reductive definitions of “culture.”
Causes of Vulture Decline
- Main cause in India is described as diclofenac and similar NSAIDs used in livestock; vultures ingest residues in carcasses and die. Diclofenac has been banned for veterinary use there since 2006, with safer alternatives recommended.
- Human NSAID use as a danger to vultures at Towers of Silence is raised as a question, but impact is unclear in the thread.
- Some note that plunging vulture numbers predate and go beyond the specific burial-rite issue.
- In Africa, poachers allegedly poison carcasses to avoid anti-poaching patrols detecting vultures circling kills.
- Others mention lead and other pollutants as causes in different regions.
Vultures, Poison, and Rodent Control
- Multiple comments stress that rodent poisons can kill vultures and raptors; traps and non-toxic baits are recommended instead.
- Some users report stable or increasing turkey vulture populations in parts of the US; others note local declines, with rat poison suspected.
- Discussion over whether vultures circling always indicates carcasses: some say circling often relates to thermals and soaring; others have repeatedly seen circling over carcasses. Consensus: circling can mean food, but not always.
Zoroastrianism and Burial Alternatives
- Reports from Iran describe historic Towers of Silence as unused for decades, with newer, religion-compatible burial buildings used instead.
- Some suggest this shows the religion can adapt its rites; others note Iran’s political context complicates religious practice.
- A side thread discusses Zoroastrianism’s status as an Indo-European religion and its demographic decline due to low fertility and restrictive conversion/marriage rules.
Wider Reflections on Death Practices and Ecology
- Commenters compare sky burials to emerging practices like human composting, contrasting them with modern embalming and sealed coffins that slow decomposition.
- Several emphasize that the extinction risk to vultures and ecosystem impacts are more concerning than the loss of a specific rite, while others see both as important.
