How do you conduct interviews to gather the most personal and emotionally resonant stories possible?
How do you push the boundaries of capturing unprecedented aerial images?
How do you weave all these sequences together to create a unique and moving work?
Through behind-the-scenes footage filmed in Paris and around the world, as well as interviews, Yann Arthus-Bertrand and his team recount these three years of work, this remarkable human adventure that led to the creation of this extraordinary work.
