Nate, if you had to guess how much of the surface of the earth is ocean and how much is land?

I don't really know numbers, but I think it's pretty obvious more of it is ocean.

You'd be right. I spoke with Explorer Victor Viskobo recently and he told me that 70%

aka most of the planet is ocean and that's not all.

Of that at least 80% is completely unexplored. So if you do the math, more than 56% of our entire planet

is completely unexplored and unmapped, which is an extraordinary figure.

Wait, 56% of the entire planet hasn't been touched?

That's kind of amazing to think about.

It is, and it's stats like that that inspire Victor

to go out into the world as an explore,

constantly searching for new frontiers.

We've heard from a lot of explorers on the show so far searching in space,

but Victor's dream destinations for his adventures were a little closer to home.

It shocked me that in the year 2014 when I... His adventures were a little closer to home.

It shocked me that in the year 2014 when I first started thinking about this mission,

that no human being had been to the bottom of four of our world's oceans.

And yet we were exploring Mars. There was a disconnect there and I come from a

culture in Texas and other places where we kind of ask a question well if

if not me who one can't always just depend on government or other people

to do things that you think need to be done.

And I've been mountain climbing pretty seriously

for about 25 years and was looking for a bit of a different challenge.
