I learned to be a hot-air balloon pilot to take tourists over the Masai Mara Reserve in order to earn some money and finance the work I was doing with my wife, Anne. We were studying the life of a family of lions for more than two years. Taking pictures was a way to capture information we could not put in words.

The trust we build over the years if of tremendous help to me when I start in a new project and need to find associates.

I never lose an opportunity to speak about my obsession: humankind and the environment.

One fifth of human kind depend on fish to live. Today now 70 percent of the fish stock are over-exploited. According to FAO if we don't change our system of fishing the main sea resources will be gone in 2050. We don't want to believe what we know.

I always take hundreds and hundreds of pictures. I used to work for National Geographic, and they gave us a lot of film.

The key of 'The Earth from Above,' and of 'Home' is to show the beauty of the planet, and thereby to promote love for it.

For nearly two years, I was flying above the planet with my camera. I knew straight away that this was something important to do, just at this moment, a portrait of the planet for the millennium year. I worked in 80 countries, fighting for money all the time.
