Trapped underneath the boreal forest and wetlands of northern Alberta are these vast reserves of this sticky, tar like bitumen.

And we got to thinking for various reasons it ought to be a desert mountain, so we got looking in the dry areas of the Southwest.

All across the boreal, we're blessed with this incredible abundance of wetlands.

During the aphelion in July, when the Earth is the farthest away from the Sun, it also happens to be winter in the Antarctic, which creates a double whammy of cold for the southern pole.

The tar sands could threaten not just a large section of the boreal.
