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 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.

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

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

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

I'm glad I'm inspiring somebody.

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

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

I am really sobered by what's happening to ecosystems around our planet and to the wildlife that is to be found there.

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

Life in this village is like that of a louse hanging on to a wrinkle in a loincloth.

It is a mistake to look too far ahead. Only one link in the chain of destiny can be handled at a time.

I'm learning a lot about how to be one of the 'good' actors. You'd hope that it's natural to be a good person, and kind, but I'm learning how to deal with long, sometimes boring days.

I love swimming in rivers, and well remember once jumping in at Chiswick.

You've got to suffer for your art sometimes!

These Americans believe that everything is possible.

America is still a country of choices and options. And I have a lot of them.
