Decline of Indian vultures

Ecological role of vultures

• Some commenters ask what species fill vultures’ niche. Answers mention wild dogs and possibly striped hyenas.
• Wild dogs are described as a problematic replacement: they spread rabies and other diseases, can attack people, and their waste is said to be plant‑toxic, unlike vultures’ guano.
• Others note that evolution to create a new, diclofenac‑resistant scavenger would be slow and unlikely to keep pace with rapid human‑driven change.
• There is debate over “nature is very efficient”: several argue nature is only “good enough” for survival, not optimized for human goals.

Sanitation, carcass disposal, and human health

• Commenters highlight that modern sanitation should not depend on vultures; carcass dumps near people are seen as the deeper problem.
• Even away from streets, carcasses in landfills or open countryside still benefit from scavengers.
• Some are surprised that landfilling large animal carcasses (including in the US) is a standard option; others note common ranch practice of dragging carcasses away for coyotes to clean up.

Biodiversity and ecosystem services

• One thread tackles “why care about biodiversity?”:
  • Arguments: interdependence of species, resilience to disease and climate shocks, avoidance of famines, and future medicines from plants/animals.
  • Examples used: crop diseases (bananas, potatoes, vines, olives), soil degradation, coastal erosion, mangroves, and Amazon deforestation.
• Counterpoints emphasize that monocultures currently give very high yields; some consumers see little direct impact when one region fails because imports substitute.
• Others stress long‑term risk: monocultures feed more people now but are fragile; failures can cause mass starvation, especially where welfare and safety nets are weak.

Study methodology and causation

• Several participants question how confidently the paper attributes ~100k extra deaths per year to vulture loss, pointing to correlation vs causation and possible confounders.
• Others note the full working paper (95 pages) details methods and that the authors themselves use cautious language (“results suggest”).
• Some see the headline numbers as potentially overstated by media, despite likely real social costs.

Diclofenac and policy response

• Timeline recap: vulture declines noticed in the 1990s; diclofenac identified as the key cause only around 2004–2005.
• India banned veterinary diclofenac in 2005–2006 after confirming vulture‑safe alternatives; commenters see the lag as scary but partly explained by scientific uncertainty and regulatory pushback.

AI‑generated comments and bots

• A large sub‑thread discusses obvious AI‑like comments on HN:
  • Patterns: new accounts, generic “interesting + summary” posts, highly similar phrasing.
  • Motives speculated: karma farming to later manipulate votes, paid boosting of stories, propaganda by state or commercial actors, or hobbyist experimentation.
• Some note that only the clumsiest bots are visible; more sophisticated ones may already blend in.
• Broader concerns: erosion of trust, difficulty forming real human connections, astroturfed “authentic” opinions and product feedback, and the “firehose of misinformation.”
• There is debate over how good bots already are, whether they’ll become indistinguishable from average humans without AGI, and how much that matters to users seeking real human, timely reactions.
