Decline in vulture population lead to the death of human beings
The decline in vulture populations in India has had severe consequences for human health.
Cause of Decline:
The vulture population in India plummeted by up to 99.9% since the mid-1990s due to the use of diclofenac, a veterinary drug used to treat cattle.
.
Diclofenac is toxic to vultures, causing kidney failure and death when they consume carcasses of treated livestock.
Impact on Ecosystem:
Vultures play a crucial role in the ecosystem by consuming animal carcasses, which helps prevent the spread of diseases.
With the decline of vultures, carcasses were left to rot, leading to an increase in feral dog populations and other scavengers.
Spread of Diseases:
The increase in feral dogs led to a rise in rabies cases and other zoonotic diseases.
The absence of vultures allowed bacteria and pathogens to proliferate, contaminating water supplies and spreading diseases.
Human Deaths:
A study estimated that the decline in vulture populations resulted in approximately 500,000 additional human deaths between 2000 and 2005.
These deaths were primarily due to the spread of diseases that vultures would have otherwise helped control.
Economic Impact:
The economic cost associated with these premature deaths was estimated to be more than $69 billion per year.
The decline of vultures highlights the interconnectedness of ecosystems and the importance of each species in maintaining ecological balance.
