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.

When you're in the middle of nowhere, when you're on this tiny little island, probably one of ten people ever to step foot on this island, it's taken you a week to get there by boat - and you step near to an albatross nest. It doesn't even look at you as the enemy. You get this great nature moment. Until you realize the albatross, along with the thousands of other winged albatrosses next to it, has constructed its nest of trash.

Whether it's exploring the woods around where I grew up, or even today exploring the coastal habitats and environments where I live in New England, or in a remote wilderness we're featuring in one of my series - I love to be in the field and I love to explore.

I'm a biologist. At my core, I'm a naturalist.

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.

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.

It's the best - combining the mediums of television, documentary, and books, to give you this transmedia experience for kids, for families, and for teachers.
