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.

I can be an artist a posteriori, not a priori. If my pictures tell the story, our story, human story, then in a hundred years, then they can be considered an art reference, but now they are not made as art. I'm a journalist. My life's on the road, my studio is the planet.

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.

More than ever, I feel that the human race is one. There are differences of colour, language, culture and opportunities, but people's feelings and reactions are alike. People flee wars to escape death, they migrate to improve their fortunes, they build new lives in foreign lands, they adapt to extreme hardship….

I have been photographing the portrait of an end of an era, as machines and computers replace human workers. What we have in these pictures is an archeology.

I try with my pictures to raise a question, to provoke a debate, so that we can discuss problems together and come up with solutions.

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.
