Fossil fuels.

I was listening to a podcast by Dr. David Suzuki yesterday where he interviews Dr. M. Scott Taylor, the Canada Research Chair in International, Energy, and Environmental Economics at the University of Calgary.  Dr. Suzuki was interviewing Dr. Taylor about the burying of carbon dioxide emissions, referred to as "carbon capture and storage" or "CCS".  So, I guess this is where we've arrived: we've accepted that we are not wise enough collectively to change our exploitation and destruction of the part of the planet we already inhabit, so we're going to have to aggressively look for other parts to exploit.  There is already a fairly significant amount of space garbage.  I guess this is the opposite.  I would like to note for the record that although the podcast was Dr. Suzuki's podcast, The Bottom Line, which is adapted from his radio show on CBC, he did not appear to be in favour of CCS.  As a matter of fact, I would say he disagreed as strongly as I've ever seen a Canadian disagree with another Canadian (a little joke for the Americans reading this blog).  We are a polite and agreeable bunch North of the border.
