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.
Tar sands have affected over 75% of the habitat in the Alberta taiga forest due to the clearing of the forests and the oil ponds that come from the extraction. These tar sands also create awful toxic oil ponds that affect wildlife and surrounding vegetation. Oil extraction also affects the forest soil, which harms tree and plant growth.

Tar sands get a lot of bad press, much of it to do with the fact that the extraction and processing of tar sands bitumen creates a lot more pollution than other fuel sources. A few companies are ...
Syncrude's Mildred Lake plant (MLSB) in the Athabasca oil sands. The Alberta's oil sands "emit high levels of air pollutants" based on a May 25, 2016 article entitled "Oil sands operations as a large source of secondary organic aerosols" in Nature in June 2016 by lead author John Liggio and a team of Environment Canada scientists.
The largest single plant in Canada to use in situ production is Imperial Oil's Cold Lake oil sand plant. This plant uses a technique called cyclic steam injection . Using this method, the company pumps high-pressure steam into a section of the underground reservoir for a week or so, then pumps the liquid oil out for as long as several months.
The Tar Sand Triangle is the largest deposit of oil sands in the United States known today. It contains about 6.3 billion barrels of heavy oil, but is thought to have originally held more. At one point the Tar Sand Triangle could have consisted of 16 billion barrels of heavy oil, almost as much as in Utah today. [3]
In the La Brea Tar Pits, more than one million bones have been recovered since 1906. 231 vertebrate species, 234 invertebrate species, and 159 plant species have been identified. [9] The most frequent large mammal found in the La Brea Tar Pits is the dire wolf , one of the most famous prehistoric carnivores that lived during the Pleistocene ...
