To have success in your professional life is not so hard. To succeed as a man is more difficult.

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

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

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

After Hurricane Katrina, over New Orleans, my helicopter crashed and the pilot and I were only saved because we fell on the roof of a flooded house that absorbed the shock. When the helicopter was spiraling downward out of control, I didn't expect to survive at all.

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.

To have success in your professional life is not so hard. To succeed as a man is more difficult.
