As you can probably tell from the title, this book is about one-hundred different places in the world that are disappearing—that are endangered in some way, by pollution, population, overfishing, poverty, or neglect. They include sparsely-populated islands, indigenous Siberian nomad land, the location of the world’s oldest tree (Sweden), ecologically-unstable reefs from around the world, and polluted oceans. None of this information is overwhelming, and it most of the book is made up of amazing photographs showing each location. This was very well-researched, and every place has a small soundbite of the area’s history and its current state. This book isn’t a depressing book about the devastation of nature around the world. The photographs are breathtaking. There are gorgeous shots of the moving sand dunes in Namibia, castles in Spain, and Australian wetlands. I’ve never heard of some of these places, and I was fascinated in all of the different cultures featured (e.g. Mongolian nomads, Saimi tribes in Norway, sea gypsies in Myanmar, San tribes in Namibia). This is definitely one of the coolest, most informative books I’ve ever read. The only problem is that now I want to travel to all of these places.
