When I was just starting out, I met Cartier-Bresson. He wasn't young in age but, in his mind, he was the youngest person I'd ever met. He told me it was necessary to trust my instincts, be inside my work, and set aside my ego. In the end, my photography turned out very different to his, but I believe we were coming from the same place.

What I want is to create a discussion about what is happening around the world and to provoke some debate with these pictures. Nothing more than this.

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 looked through a lens and ended up abandoning everything else.

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.

The language that photography has is a formal language. Any photographer is doing something formal. If it's formal, then it must be an aesthetic way to communicate.
