on his blog. You can also learn a lot about it from a great book that is going to be published next week--Tar Sands: Dirty Oil and the Future of a Continent. The publisher thinks it's so important for everyone to understand this critical issue that--you won't believe this--they're allowing people to download the entire thing on PDF for free between March 16 and March 20!! Please take advantage of this to learn about tar sands oil. As Jeff Wells notes on his blog, this is "the world’s most harmful type of oil for the atmosphere, emitting high volumes of greenhouse gases during development, which contribute to global warming, as well as other pollutants. Tar Sands projects are the largest contributor to greenhouse gas emissions growth in Canada. By 2015, the Tar Sands are expected to emit more greenhouse gases than the nation of Denmark (pop. 5.4 million)."
Remember, if you can read the PDF on your computer rather than printing it out, you'll be saving paper--and that helps the Boreal forest, too!
