Pop quiz

Scott Stinson has trouble with this whole "analogy" idea. So let's spot the non-natural phenomenon in his attempt to downplay the effects of the tar sands on the environment:

A photograph has been making the rounds on the Internet of a bison being chased by a grizzly bear along a road in Yellowstone National Park.

It’s a remarkable shot because the bison in question appears to have escaped the clutches of the bear mid-mauling. Chunks of its fur are missing, and it is literally running for its life, with a rather angry-looking Yogi in determined pursuit.

A park official told a Montana television station this week that the photo is real. Not that anyone at Yellowstone is searching for the bear, or its presumed victim. It’s just one of those brutal things that happen in nature.

You know what else happens in nature? Birds migrate. And so, this week, Alberta energy giant Syncrude again finds itself as the scourge of the oil sands because some of those birds took a detour and landed on one of its toxic wastewater ponds.
