With a new afterword Why You Are Here A speech on the opening of the COP26 climate summitAs a young man I felt I was out there in the wild experiencing the untouched natural world but it was an illusion. The tragedy of our time has been happening all around us barely noticeable from day to day the loss of our planets wild places its biodiversity. I have been witness to this decline. A Life on Our Planet contains my witness statement and my vision for the future the story of how we came to make this our greatest mistake and how if we act now we can yet put it right.We have the opportunity to create the perfect home for ourselves and restore the wonderful world we inherited.All we need is the will do so.
