To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This book has some good concepts, good concepts you would of already known if you ever bothered to read news or magazines like National Geographic, or Popular Science. It's also telling the story in a really inefficient way. Every chapter of the book can be easily shrink down to a paragraph, and the readers can get just as much out of it. (With that said, the whole book could of been a less than 15 paragraph article.) Plus with some of the author's Utopian dream talk, this book is simply a waste to purchase. I'd say if they never published this book, they could do earth a great favor and save thousands of trees. I guess the author was really trying to extend that 15 paragraph to a near 400 pages book so that he can make more money out of it, instead of really being conscious about saving the environment as he pretends to be in the book, that I don't blame him in this sorry economy.
