I'm glad I'm inspiring somebody.

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.

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.

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

You have been blessed with immeasurable power to make positive changes in your life.

Man belongs to his Maker.

Screenwriting is not an artform, it is a punishment from God.

It's hard to get movie studios to pay a lot of money for movies that don't have robots or explosions.

The Way is the source of all things, good people's treasure and bad people's refuge.

There's a lot of good things about England, but I don't want to tell you too many of them.

I've always had a respect for psychiatry as a profession.
