The number one issue that Ocean Mysteries has opened my eyes to is, no matter where you are, whether you're on a beach in Hawaii, you're diving in the Pacific, you're in a remote archipelago, or you're in the middle of nowhere - I am blown away and sobered and crushed, emotionally crushed, by the amount of marine debris, of garbage, that is now in our ocean.

We live in uncertain times when it comes to the future of life on Earth.

To be with another scientist and make a discovery and share that with a global audience, or working with bear biologists in Alaska, by helicopter - [it's] really what I've given my whole life to. And I get to do that just about every week.

In my heart, ever since I [was] a little kid, I've been an explorer.

I love people who have died trying to save wildlife. When I see that passion, that gives me hope.

What drives me is that moment of discovery. I love the unknown.

I think the hardest part about my job is the best part of my job - the travel.
