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.

As in any person's life, there have been difficult moments: I have a son with Down's syndrome; through my photography, I have witnessed all manner of human degradation. But there have also been very happy moments.

I work on stories rather than individual pictures.

There are moments that you suffer a lot, moments you won't photograph. There are some people you like better than others. But you give, you receive, you cherish, you are there. When you are really there, you know when you see the picture later what you are seeing.

You photograph with all your ideology.

I am a former economist. I never went to photography school to learn photography.

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