OK, one might say, that I fell into a merchandising trap, when buying this, but I openly admit, that the movie "Avatar" did touch something inside me, that goes beyond the action and effects of a typical James Cameron film.
This book is the "field guide" to the fictional world of Pandora, and despite being part of a money-making machine here on Earth, it's filled with criticism of consumerism, ecocide and the deadened feelings of the inhabitants of a dying world (in this case, our own Earth in a near future).
The introduction is entitled "Warning", since the book is written as being an illegal field guide, comprised of smuggled notes for possible activists wanting to change what Earth has become - or might become in the future, if we don't act now.
Here's the beginning of it, sounding eerily current and very familiar today already:
"The armies of greed lay waste to the Earth and all its creatures. In our hunger for energy - for more and more - we've devastated our planet. We're neck-deep in festering industrial muck, in a trash heap of ever-expanding waste and decay. Overpopulation, overdevelopment, nuclear terrorism, environmental warfare, radiation leaks from power plants and waste dumps, toxic runoff, air pollution, deforestation, global warming, ozone depletion, loss of biodiversity through extinction... our once blue-green and beauteous Earth is now a terminal cesspool - an oozing wound cut deep into the face of the universe. Dollar for dollar, we've bought our extinction."
