Poisoned vultures clear the way for a plague of rabies

摘要

A conservation catastrophe has become a human tragedy. The mass poisoning that has killed millions of India's vultures may have indirectly claimed the lives of almost 50,000 people, according to an analysis of the wider impacts of the bird die-off. Since the 1990s, numbers of long-billed, slender-billed and oriental white-backed vultures have declined at an unprecedented rate. All three species could be driven toward extinction within a decade. The cause is a veterinary drug called diclofenac, which was routinely given to cattle. When the cattle died, vultures that fed on their carcasses were poisoned by the drug. Although now banned in India, diclofenac is still used to some extent.
