There are many dangerous places covered on the channel, the most obvious of which are the caves, with their claustrophobia-inducing squeezes and deep water-filled tunnels.

But the cave in this video is different.

It has none of those, and yet it might be the single deadliest cave on Earth.

These are some of the most dangerous places on Earth, and as always, viewer discretion is advised.

Roughly five years ago, for a time the world stood still.

Airports empties, cities dimmed, loved ones were separated, holidays were skipped, and plans

were put on hold.

For those who fell ill or lost someone who did, the pain was deep, but the global pandemic

was more than just a global health crisis.

Behind the scenes, scientists began issuing a new kind of warning that this might not be the

end of it.

This is because pandemics don't just come out of nowhere.

Often they come from hidden places where humans and wildlife meet under the wrong circumstances,

like in caves, forests, and wet markets.

They start in blood, saliva, and even dust, and one of the most alarming candidates for

the next outbreak isn't a distant lab or a bustling urban center.

Instead, it's in a cave on the slopes of an ancient

volcano in the green highlands of East Africa. That place is known as Khatoum Cave, dubbed by some

as the most dangerous place on Earth. If you've followed the channel for a while, you've probably

heard at least one of the cave disasters, but this is not one of those typical cave stories.

Instead, Khatoum Cave is something that can and very well may affect all of us one day,

whether we've sworn off entering a cave or not.
