Discover the real truth about the biggest oil deposits in the world and the stunning environmental impact of oil exploration in the spectacular scenery of Alberta"s oil country. Concerns about the future supply of conventional oil have attracted new attention to the potential yield from "oil sands." Walking on oil - Alberta"s Oil Sands focuses on the Province"s crude bitumen oil sands - estimated to be the World"s largest hydrocarbon deposits. According to the World Energy Council, Alberta"s reserves are estimated to stand at least 1,600 billion barrels. Certain experts claim that Alberta"s oil sands contain more petroleum than Saudi Arabia"s oil fields and enough resources to supply Canada"s energy for more than 475 years or total world energy needs for up to 15 years. But does the World need this oil resource? Alberta"s Oil Sands - The Problem and the Conflict: The fuel from the tar sands is thick and heavy and is bound to water and sand. Extraction of the oil and refining it destroys countless miles of irreplaceable forest land and requires enormous amounts of energy and water. Tar sands oil production creates 2 to 3 times as much greenhouse gas as production of conventional oil hence the contribution to global warming. Enormous machinery is used to remove trees, rocks, soil and sand from the earth and once the tar sands are removed, the resulting huge holes in the ground remain along with the toxic water-borne tailings. As the Greenland ice cap melts (and melting is well underway) it may raise ocean levels by 20 feet, flooding major cities and coastlines worldwide. As a world together, we have to make the right decisions about the extraction and use of Alberta"s immense oil resource.This product is manufactured on demand using DVD-R recordable media.
