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

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

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

We are one human race, and there must be understanding among all men. For those who look at the problems of today, my big hope is that they understand. That they understand that the population is quite big enough, that they must be informed that they must have economic development, that they must have social development, and must be integrated into all parts of the world.
