Canadian Tar Sands --
Dubbed by some as the "most destructive project on Earth" - scarring it visibly from space - there's no doubt that the tar sands extraction industry has a huge environmental footprint.To extract each barrel of oil from a surface mine, the industry must first cut down the forest, then remove an average of two tons of peat and dirt that lie above the oil sands layer, then two tons of the sand itself. It must heat several barrels of water to strip the bitumen from the sand and upgrade it, and afterward it discharges contaminated water into tailings ponds. The oil sands are still a tiny part of the world's carbon problem—they account for less than a tenth of one percent of global CO2 emissions
