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 West has become the world model; developing countries are dreaming of living like us, which is impossible. They should reject our model, because it is not sustainable. Developing countries should even give us the example, but unfortunately that's not what happens.

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

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.

It's time to come together. We all have the power to change, so what are we waiting for?

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.

The lions taught me photography. They taught me patience and the sense of beauty, a beauty that penetrates you.
