Tar sands are still around, even though I first wrote about them in February 2009! The Sierra Club is trying again to wake people up about this source of oil with a new campaign, It's Time to Move Beyond Oil which may not be coming from Saudi Arabia, but is definitely not what we want our future source of energy to be.
The main purpose for the Keystone XL Pipeline is to carry the extremely dirty tar sand oil to US refineries. As you can see in the video, the oil is so corrosive it regularly corrodes the pipes, leaking its toxic mess into our water sources.
We all think of Canada as being environmentally responsible, but its current and most recent conservative governments have been tearing back environmental protections in Canada, and trying to see this poison the the US.
We don't want it!
