The Earth is Art, The Photographer is only a Witness.

For me, an aerial picture is no different than a close-up portrait. It's a question of framing and angle. Helicopters are great for that. But I've also used planes. Of course, I always have a harness.

I always take hundreds and hundreds of pictures. I used to work for National Geographic, and they gave us a lot of film.

I'm not an expert when it comes to technology, but what changed things for me was autofocus. I used to have to throw away half my pictures because it was so difficult to get the focus right.

I never lose an opportunity to speak about my obsession: humankind and the environment.

The lions taught me photography. They taught me patience and the sense of beauty, a beauty that penetrates you.

The Rio Earth Summit in 1992 changed my life completely, turning me into an activist. From the air, you see things you can't see from the ground - you really understand the impact of man, even in a place you know well. My work is meant to convince people we can no longer live like this.
