Al Gore has made an effort to make the uncomfortable truth about global warming more intelligible to those who will have to confront it in the near future: the young. And he has done it trying to infect them, through his exhibition rigor and the beauty of the images contained in this edition, his love for nature and for the environmental balance of this planet. His is an optimistic and hopeful message, based on the conviction that, if we propose it from now on, we can still avoid among all the worst effects of climate change. For this reason, as it is aimed at young people, this book reaches its maximum reason for being and its publication acquires full and total meaning.
