I'm not a religious person. The language of photography is symbolic.

The light in Alaska in particular is so beautiful. So beautiful! Such incredible light.

So many times I've photographed stories that show the degradation of the planet. I had one idea to go and photograph the factories that were polluting, and to see all the deposits of garbage. But, in the end, I thought the only way to give us an incentive, to bring hope, is to show the pictures of the pristine planet - to see the innocence.

I discovered that close to half the planet is 'pristine.' We live in towns such as London, Paris or Sao Paulo and have the impression that all the pristine areas are gone, but they are not.

Of course I will continue photography. I love photography. But when you become old, it's too much.

I don't want anyone to appreciate the light or the palette of tones. I want my pictures to inform, to provoke discussion - and to raise money.

I looked through a lens and ended up abandoning everything else.
