ABC continued its weeklong series on the Oil Crunch from Canada. After David Muir's trip to a Gulf of Mexico oil platform and Betsy Stark's visit to a Port Arthur refinery and anchor Charles Gibson's carbon-neutral sitdown (here and here) with the boss at ExxonMobil, Bill Weir toured the oil sands of Alberta. Bitumen is strip mined from fields six miles in diameter by monster trucks that are three stories high "with side mirrors the size of refrigerators." Virgin forests are being destroyed to retrieve pitch that is "gooey and sloppy in the summer sun." Processing the tar produces triple the volume of greenhouse gases compared with conventional crude. Generating each barrel of oil uses four barrels of water whose waste is dumped in toxic reservoirs. "Poisoning the earth, air and water," Weir concluded.
