The Sixth Extinction: An Unnatural History

Clear and well written, this book paints a pretty gloomy picture about the future of the planet. Oh, humans will probably survive, even if we have to build biospheres in which to do it, but most other species will go the way of the dodo and the T-rex. (This makes me want to read more about paleontology and plate tectonics and a number of other subjects that are dealt with briefly here.)
