We live in a time where we have more extinction happening on our planet than since the dinosaurs were wiped out 50 million years ago.

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

We live in a time where we have more extinction happening on our planet than since the dinosaurs were wiped out 50 million years ago.

I am really inspired when I am in an experience, at the front lines of conservation, and I see someone - a woman, a man, a child, a person - who has given up an opportunity to have a family, an opportunity for financial riches, even an opportunity for security, [to] put their whole life on the line to protect a species.

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.

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

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.
