For Arthus-Bertrand, who has been filming the planet and its people for four decades, Human is an exploration.

"I feel that humanity is not making any progress. We cannot always manage to live together. So why?" the director asks.

"I didn't look for answers in figures, but I've tried to seek it from men themselves," he says.

"Do we all have the same thirst for love, freedom and recognition? In a world torn between tradition and modernity, do our fundamental needs remain the same? Deep down, what does it mean to be human today?"
