Shifting Sands —- Canada, The World And The Tar Sands

The tar sands consist of a mixture of silica sand, minerals, clay, water, and most importantly, crude bitumen. The process of converting bitumen so that we can use it to power our cars, heat our homes, and transport our food is not easy. It’s estimated that two tonnes of earth must be excavated to produce one barrel of thick tar-like bitumen. And it requires as much as three barrels of fresh water from the Athabasca River to make one barrel of bitumen. It also takes a huge amount of energy to extract the oil from the sands. Now think about this: each day Canada exports one million barrels of bitumen to the United States. ((23 NOV 2010))
