Twelve years after his ground-breaking film, Home, photographer Yann Arthus-Bertrand portrays a world in worse condition: mankind lied to itself for decades either unable or unwilling to take the imminent threat seriously. Today, no one can deny the ecological mess we are in. Through his efforts to transform, dominate, and deviate energy, mankind has disrupted nature’s order of things. At stake is our survival, for which we are all responsible. Yann Arthus-Bertrand offers his legacy, which is also ours. Behind the beauty of his photographs a painful cry can be heard. Legacy provides us with the reasons and courage to face this reality: we must return to nature and work for the planet and our children’s future.
