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

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

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

We know that when push comes to shove, [we can] drive ourselves to save our planet.

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 glad I'm inspiring somebody.

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.
