Even small changes to their conditions can quickly throw everything off.
Researchers have found a troubling link between tourism and the survival of Earth's largest lizard, according to Tempo.
Komodo National Park in Indonesia -- home to the world's biggest lizard, the Komodo dragon -- is at risk from the same visitors who hope to see one of these incredible creatures.
Tourism brings money and attention to the facility, but it's also quietly hurting the Komodo dragons' health and home.
Raden Wisnu Nurcahyo, a wildlife observer and veterinary professor at Gadjah Mada University, has found that close contact with humans can spread diseases to the reptiles.
"Parasitic diseases, worm infestations, and infections from humans can also affect the Komodo population," he explained, as reported by Tempo.
It's not just illness that is causing harm either. Resort construction, plastic waste, and the buzz of tourist boats are all straining the fragile island ecosystem.
"Excessive natural exploitation for tourism has downstream effects," Nurcahyo said. "If we want the Komodo to stay healthy, its environment must also be preserved."
There are an estimated 3,000 Komodo dragons left living on just a few scattered islands in Indonesia.
As people continue to encroach on their traditional habitats, it gets even more difficult for these lizards to live in the wild.
Even small changes to their conditions -- such as dirty water or damaged nesting spots -- can quickly throw everything off.
"If its numbers keep falling, the Komodo may end up like the dinosaurs, merely recorded in history books," Nurcahyo warned.
If that happens, it's not just about losing a prehistoric creature.
These lizards keep smaller animals in check, maintaining the delicate balance of the region. Without them, the entire local ecosystem can be compromised, including the food chain.
To slow the damage, Indonesia has limited visitor numbers, increased park fees, and tightened rules to protect Komodo habitats.
Conservation groups are studying the spread of disease between humans and wildlife. At the same time, local rangers patrol nesting sites to stop poaching.
Visitors can help by opting for smaller, eco-certified tours, maintaining a respectful distance. Supporting local guides over large operators that overcrowd the islands can be effective as well.
The Komodo's story isn't unique.
Bali's reefs, Thailand's elephants -- it's the same issue again and again: too many people, not enough space. But things can shift.
Travelers can leave lighter footprints. And Komodo protection efforts are about more than saving one species -- they're about preserving the wilderness for all of us.
