Nature's my muse and it's been my passion.

It's up to us as photographers to give voice to the natural world.

I think a photograph, of whatever it might be - a landscape, a person - requires personal involvement. That means knowing your subject, not just snapping at whats in front of you.

A lion is not a lion is not a lion. As individuals, as mates, as members of a society, they're all very different.

Life is a force in its own right. It is a new element. And it has altered the Earth. It covers Earth like a skin.

Biodiversity starts in the distant past and it points toward the future.

Water is the key to life, but in frozen form, it is a latent force. And when it vanishes, Earth becomes Mars.

Life needs a membrane to contain itself so it can replicate and mutate.

Tourism is important because it can create sustainable local economies. Id much rather have 1,000 tourists going up the Tambopata than 1,000 gold miners.

At some point, you just gotta forgive the past, your happiness hinges on it.

Sometimes I just get tired. I get headaches, and I just lose track. I mean, it's like which is me and which is the role? Where's the line between me and my shadow?

In proportion as one renders service he becomes great.

We shouldn't deny the pain of what happens in our lives. We should just refuse to focus only on the valleys.

Like I say, it depends on how you do rock-'n'-roll. If you do it right then I think people will appreciate it for what it is.

Fresher than a pillow with a mint on it

Patient perseverance in well doing is infinitely harder than a sudden and impulsive self-sacrifice.

I think self-esteem is fluid. It's not a fixed state, and so some days are better than others.

I desire ... to leave this one great fact clearly stated. THERE IS NO WEALTH BUT LIFE.

Some persons do first, think afterward, and then repent forever.
