Vultures Vanish: India's Scavengers Face Extinction

India's iconic vulture population has suffered a catastrophic decline, plummeting from an estimated 40 million to just 30,000 over the past three decades. This dramatic fall is primarily attributed to the widespread use of the veterinary drug diclofenac, a potent painkiller. When cattle treated with diclofenac die, the drug persists in their carcasses, proving fatal to vultures that scavenge them. The drug swiftly causes kidney failure and other organ damage, leading to widespread mortality.

The consequences of this ecological collapse extend beyond the birds themselves. Studies indicate that the near-extinction of vultures has led to a significant increase in human all-cause mortality rates, estimated at over 4% in affected districts. This "sanitation shock" is linked to a rise in feral dog and rat populations, coupled with a decline in water quality, as the natural carcass-clearing services of vultures are lost.

Conservation efforts are underway, including captive-breeding programs and reintroduction initiatives. However, experts emphasize that immediate and strict bans on diclofenac and other vulture-toxic drugs are essential for recovery. The survival of these vital scavengers depends on preventing further exposure to these harmful chemicals and ensuring new veterinary drugs are rigorously tested for their impact on scavenging birds.
