British Isles: A Natural History takes the reader on a journey through time, from the explosive birth of the islands to the rich and varied landscape of today. It chronicles the evolution of this unique land, exploring everything from geology and geography to flora and fauna. The story begins 3 billion years ago, when primeval forces created the foundations of the islands, and ends in the modern era, with the landscape utterly transformed by human activity. Along the way, we encounter gigantic ice sheets, ancient forests, early human settlers, and an astonishing variety of plants and animals. At the start of the 21st century, as we look to the future, the author investigates the many fresh challenges and responsibilities Britons face if they are to live in harmony with nature.
