Here on Earth, a natural history of the planet by Tim Flannery

A fascinating view of how the earth evolved, and how all creatures but especially we humans are rapidly changing the balance of nature. Flannery begins with a review of the theory of evolution, but moves on to a fresh look at Earth as one great ecosystem. He describes how man has upset the balance of nature from the time we began to expand beyond the African plains, by hunting the largest mammals to extinction. Trouble is, those creatures were essential to the balance of some ecosystems, and without them areas like Siberia became frozen wastes. Now of course humans have overrun the planet and have radically changed much of the planet. He concludes with an assessment of the steps humanity needs to take to avoid catastrophe from latent chemical pollution and rapid climate changes, and his hope we will gather the political will to act in time. This is a very readable overview of a very broad topic, recommended. 281 p.
