"Environmental devastation of the land, water, and air - the largest industrial energy project in the world is extracting crude oil from bitumen found beneath the pristine boreal forest of Alberta, Canada. Effecting a land mass equivalent in size to Florida or England, Both industry and government are putting money before the health and security of its people and the environment.
Tar sands take 3 barrels of water to process every barrel of oil extracted. Ninety percent of this water becomes so toxic that it must be stored in tailing ponds. Unfortunately these ponds regularly leach pollution into the third largest watershed in the world.
Water depletion, exploitation, privatization and contamination has become one of the most important issues facing humanity this century."
