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.

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.

Many scientists would argue that we are now in what is called Extinction, and it's caused by this perfect extinction storm: climate change, habitat loss, pollution, unsustainable exploitation of species and habitat resources, and of course, human population explosion. All of these factors work together and conspire to drive a species to extinction on our planet, every half an hour.

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

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.

I love people who have died trying to save wildlife. When I see that passion, that gives me hope.
