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 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.

Before it was just her infernal curves that fretted me, but now I've taken her whole soul into my soul, and through her I've become a man!

Anyone who tells you they're not nervous playing on the CMAs stage, I'm afraid they're not telling you the whole story.

To get joy, we must give it and to keep joy, we must scatter it.

We all begin life as parasites within the mother, and writers begin their existence imitatively, within the body of letters.

You are what you pretend to be.

How can time be so wrong for love to come along? Catch me I'm falling for you.
