Vultures which used to be very common in the Indian countryside some years ago are rarely seen nowadays. This is attributed to
Detailed Explanation:
Diclofenac, a non-steroidal anti-inflammatory drug (NSAID) used by cattle owners to treat livestock, caused the catastrophic decline of vulture populations in India.
Vultures feeding on carcasses of diclofenac-treated cattle suffered acute kidney failure, leading to a 99% population crash of three species (White-rumped, Indian, and Slender-billed vultures) between the 1990s and early 2000s. India banned veterinary diclofenac in 2006.
