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.

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….

Photography is full of symbolism, it's a symbolic language. You have to be able to materialize all your thoughts in one single image.

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

I have a way to photograph. You work with space, you have a camera, you have a frame, and then a fraction of a second. It's very instinctive. What you do is a fraction of a second, it's there and it's not there. But in this fraction of a second comes your past, comes your future, comes your relation with people, comes your ideology, comes your hate, comes your love - all together in this fraction of a second, it materializes there.

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.

Most of the information we now get is through television and is mutilated. Photography offers the opportunity to spend much more time on a topic. It's relatively cheaper medium, and can allow a photographer really to live in another place, show another reality, get closer to the truth.
