Tar Sands: Dirty Oil and the Future of a Continent is a book written by Andrew Nikiforuk, a Calgary journalist. The publisher, Greystone Books, has decided to make it available as a free PDF until Friday, March 20th. The book’s description suggests that it is very critical of the oil sands industry, overall:
This out-of-control megaproject is polluting the air, poisoning the water, and destroying boreal forest at a rate almost too rapid to be imagined. In this hard-hitting book, journalist Andrew Nikiforuk exposes the disastrous environmental, social, and political costs of the tar sands and argues forcefully for change.
Getting the PDF requires that you give them your email address. Of course, you can always buy the book if you prefer.
