I'm glad I'm inspiring somebody.

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.

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

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

I think a human animal is far more wild and unpredictable and dangerous and destructive than any other animal.

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.
