I borrowed this book from the library, but, although I enjoyed it to some extent, I am not sure whether I found it useful or not, or whether I discovered anything that I did not already know.
The basis of the book is do not believe everything you read - an old adage, and surely not something to base an entire book on. The author uses some good examples to show how surveys, 'scientific data' and everyday media reporting cannot be taken at face value - look to see if there is a hidden agenda and who is paying for the research.
There are some good points to the book, it is easy to read, and does not contain anything that requires any previous environmental or scientific knowledge to understand. It does have an introduction to a topic before launching a critique of the media coverage, and the author does appear to be fairly objective about the topics covered - and there is a huge raft of topics covered in the book.
The thing that stops me giving it four stars is that to me, everything is fairly obvious, but, I do read a lot of information about environmental issues. However, if you are feeling a little overwhelmed by the arguments and counter arguments that are in the media these days about issues from global warming to organic farming and alternative energy sources then this is probably a good place to start to get a balanced view (at the very least borrow it from your library).
