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

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.

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'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.

Royalty is either going to do very well with cloning, or it's going to disappear completely.

Don’t concern yourself with the money. Be of service ... build ... work ... dream ... create! Do this and you’ll find there is no limit to the prosperity and abundance that will come to you.

I have watched a lot of Tendulkar and we have spoken to each other a lot. He has it in him to be among the very best.

I don't find movies interesting. I just want to do the movies that made me interested in getting into movies, and they're few and far between.

One doesn't always lose when one has to do without.

This is my most important role. If I fail at this, I fail at everything.

We know the costs of Europe. What are the benefits?

If they don't close these [nuclear] reactors down, we'll have civil war in five years.

The establishment can accept being screwed, but not being laughed at

It takes years to develop into the kind of human being you want to be.
