Think vultures are just gross cleanup crews? Think again. These birds—along with other scavengers like hyenas—play a critical role in keeping ecosystems (and us) healthy by devouring dead animals that could otherwise spread disease. But here’s the problem: their populations are crashing, and that’s bad news for human health too.

Editor’s Note: It’s easy to dismiss scavengers as nature’s grim janitors, but their disappearance could leave us knee-deep in rotting carcasses and the diseases they carry. This isn’t just about saving weird-looking birds—it’s about preventing outbreaks and keeping ecosystems in balance. So yeah, maybe give vultures a little respect next time.

Turns out, animals like hyenas—often seen as pests or nuisances—actually play a surprising role in keeping humans healthy. A new study highlights how these top scavengers help control disease by cleaning up carcasses that could otherwise spread pathogens. But here’s the catch: their numbers are dropping, and that could leave us more vulnerable to outbreaks.
