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.

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

Our health as a society, our robustness as a community, as a nation, as a people, is not only dependent upon fiscal stability, military might, political strength - it's also dependent on a healthy planet.

Today, I’m a conservationist because I believe that my species doesn’t have the right or option to determine the fate of other species, even ones that inspire fear in us.

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.

I'm really worried about what the world is going to be like when my daughters are young women, [when] they are young leaders or mothers or businesspeople - whatever they're going to be. I'm afraid they're going to have a less healthy and less biologically rich planet.

We are not far away from the point of no return when it comes to life on earth, and we have some radical choices to make.
