Yann-Arthus Bertrand's photographic daybook features over 200 completely new photographs. Each image is accompanied on its facing page by a thoughtful and thorough explanatory text. The images reach across the continents, from the icebergs of Antarctica to the cotton fields of India to the olive plantations of Spain. All 12 chapters of the book open with a thoughtful introduction by one of several noted authors who address a wide variety of subjects critical to the present and future health of our planet: agriculture, biodiversity, sustainable development, energy, forests, fresh water, seas, global warming. The book thus offers us a new perspective on our spectacular but fragile environment.
