In 200,000 years, humans have disrupted the fragile balance on which Earth was living for 4 billion years. Global warming, shortage of resources, endangered species: humans are jeopardizing their own living conditions. By the end of the century, the relentless consumption will have exhausted almost all of our planet's natural resources. But it is too late to be pessimistic: we have barely 10 years left to reverse the trend. We need to become aware of our abusive exploitation of Earth's gifts and change our way of life. By giving us these previously unreleased images of over 50 countries as seen from the sky, and by sharing his wonder but also his worry, Yann Arthus-Bertrand contributes to the rebuilding we all need to start doing together. Yann Arthus-Bertrand takes us on a sensational journey above planet Earth and provides us with an unusual portrait of our planet. Planet Earth is critically ill but another future is possible if we all decide to write it together.
