I spoke to Anant Sudarshan, an environmental economist at the University of Warwick who studied the fallout of this mass die-off.

Here's what he had to say.

As a result, waterborne pathogens like coliform bacteria can become a bigger problem.

Anant and his colleagues analyzed mortality data from the country and found it ticked up 4% because vultures disappeared.

That's a lot and translates to about 100,000 additional deaths a year.

Yeah, and their absence had another crucial effect.

All that extra meat ended up becoming food for feral dogs, which spiked in number.

Here's Chinmay Sonawane, a biology grad student at Stanford.

Yeah, and to Chinmay, the story of these vultures really exemplifies the huge but often hidden benefits that scavengers provide.

For sure.

Chinmay told me there's been a burst of studies looking at the relationship between human health and scavengers in the past few years.

So one study estimates that hyenas scarfing up cattle carcasses outside of one of the largest cities in Ethiopia prevents five cases of anthrax and bovine tuberculosis each year.

Yeah, yeah.

Another study found that civets and other scavengers in Malaysia actually reduce the amount of diarrhea-causing bacteria that build up on flies by quickly eating carrion so flies have less time to multiply.

Flies are a big vector for these kinds of diseases, so reducing the bacteria load on them could lead to fewer people getting sick.

They're kind of cat-like, but also like a long-legged weasel.

Google them after this.

And turtles in Australia eating carrion was associated with improvements in water quality in wetlands.

The list really goes on and on, but there's one big problem.

Yeah, like I mentioned, many of these species are declining.
