The challenge is that we live in a time where there's a lot of crap on television.

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.

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

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.

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.

Running is my addiction. It's always present. I'm constantly thinking about my next run.
