Stunning Cave Photography Illuminates an Unseen World | Nat Geo Live 

Wow. Amazing exploration. Fantastic pictures. Fascinating views inside our planet. The scale of some caves is unimaginable. Very interesting presentation.

Thank you very much !!

It's an absolute privilege to hear you talk about the hidden world robbie shone...❤️

thanks for sharing! I miss caving and as I am not able to do it these days, I'm grateful to live through other people.s experiences vicariously!

super fascinating

appreciate the good work

Caves are equally fascinating and terrifying

absolutely wonderful thanks for sharing

This inspires me so much.

Nat Geo really needs to fix where they put the mics on them. I understand giving a talk can dry your mouth but the past couple vids have been the same gulping and lip smacking

i loved this

Thank you, wow!!!

Magnificent !!

i came here after reading the jungkook ff called some little things called love

ft knox military base was built in kentucky because of the caves. the gold isn't in the gold vault its actually stored in caves.

I can't listen to people who are so monotone... I always zone out and can't remember anything they said

Jesus someone get him a glass of water before he keels over

I love the sounds coming from his mouth. Just kidding

Where is this cave at?

He really needed water! I had to stop watching it, I just couldn't take the sound anymore. Sorry Mr. Stone, the sound just wasn't right.

So, I'm sure this is a wonderful presentation and very insightful, but I made it 50 seconds in and can't handle a this disturbing swallowing and lip smacking anymore. I've noticed this being an issue with a lot of the more recent Nat Geo Live videos and it is really becoming impossible to watch. Please adjust your settings for mic sensitivity or give your team something to cure that dry mouth.

this guys……………………………voice is……………………overly dramatic

He should have had a 'dead cat' on his mic.... I would have loved to watch this, but the squishing and smacking sounds from him totally take over and makes it physically uncomfortable for my - I don't know why but 'mouth sounds' that are not words just get under my skin and overflows everything else.... and I'm not the only one! So pleeeeease use noise cancelling on the microphone, so that you don't loose a part of your audience - it's not the presenters fault, he can't change how he speaks, but the production team can do a lot to counteract wierd noices,,, had I been there I would have had to leave 🤢🙅🏻

can he be more dull and unexciting discoverer? get a girlfriend dude
