The Sands of Alberta

Back then, we were all more worried about Nuclear Winter than Global Warming, but the biggest issue by far was Acid Rain. To their credit, the folks at Syncrude actually took the time to scrub those particular emissions and had pallets of bright yellow sulphur to show for it.
    On our trip to Fort McMurray, they actually took us through the process of turning tar sand to fuel, beginning to end. Today, of course, this is regarded as one of the dirtiest ways of addressing our energy needs, but let me tell you, the sand it produces is impeccably clean.
