The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, a heavy and viscous form of petroleum, in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market. [3]
Athabasca oil sands. The Athabasca oil sands, which are situated almost entirely in Alberta, are the "fourth most carbon intensive on the planet behind Algeria, Venezuela and Cameroon" according to an August 8, 2018 article in the American Association for the Advancement of Science's journal Science. Their research concluded that "Canada's ...
The Tar Sands Healing Walk was a 14 km annual prayer walk in demonstration against crude oil extraction in the Athabasca tar sands.It began in 2010, starting just north of the city of Fort McMurray, Alberta at a location known as the Syncrude Loop, and traveling through the heart of the tar sands extraction zone.
If the study points to impacts on communities from the oil sands it would force the federal and provincial governments and companies to put stronger environmental and health measures in place ...

Oil sand tailings or oil sands process-affected water (OSPW), have a highly variable composition and a complex mixture of compounds. [4] In his oft-cited 2008 journal article, E. W. Allen wrote that typically tailings ponds consist of c. 75% water, c. 25% sand, silt and clay, c.2% of residual bitumen, as well as dissolved salts, organics, and minerals.
[3] [4] Tar sands facilities were found to be among the top four highest polluters of volatile organic compounds (VOCs)- a major air contaminant. [4] VOCs and other air contaminants are set to increase in the future as a result of continued output from the oil sands. [4] Oil sand pollution is not only set to increase VOCs, but also, acid rain.

The environmental liabilities that result from the various steps in oil sands extraction and refining process include: (i) Destruction of the boreal forest eco-system; (ii) Damage to the Athabasca watershed; (iii) Heavy consumption of natural gas; (iv) Creation of toxic tailings ponds; and (v) Increased release of greenhouse gases
