Up to about the halfway point I was thinking to myself that I've really got to stop reading these short introductions to environmental politics. It's certainly one of the better ones, though I'm not sure it stands out in the way that other books of Wall's that I've read have done. All of a sudden, though, there's a sharp turn into some pretty heavy social movement theory, and the remainder of the book is much more compelling. Chapters on the methods of denial of the right, on the psychology of convincing others, of the failings of the state, and so much more round out the book. There's only really time to skate over these topics, as it's a pretty short book, but a good starter for deeper reading.
