Martin & Philippa, the two incredible humans behind this book who care deeply for this planet, decided in to draw a symbolic line around the earth. They embarked on a global environmental art project to create twelve ephemeral sculptures in remote mountain locations around the world. The sculptures were made from natural materials found at each site, enduring only in the mind (and in photographs) as an artistic evocation of the temporary and interconnected nature of life. Their journey connected communities and landscapes around the world. This is the gorgeous pictoral souvenir of that journey.
