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.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.
