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.
Their carbon footprints, however, are radically different: conventional reservoirs use the natural energy in the environment to flow oil and gas to the surface unaided; unconventional reservoirs require putting energy into the ground for extraction, either as heat (e.g. tar sands and oil shales) or as pressure (e.g. shale gas and CBM).
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.
Oil exudes from joint cracks in the petroliferous shale forming the floor of mine. 1906 photo, U.S. Geological Survey Bulletin 321 Tar bubble at La Brea Tar Pits, California A petroleum seep is a place where natural liquid or gaseous hydrocarbons escape to the Earth's atmosphere and surface, normally under low pressure or flow.
Small tar pit. La Brea Tar Pits is an active paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural asphalt (also called asphaltum, bitumen, or pitch; brea in Spanish) has seeped up from the ground for tens of thousands of years. Over many centuries, the bones of trapped animals have ...
Raw bitumen extracted from the oil sands in northern Alberta is shipped in Canada and to the United States through pipelines, railway, and trucks. Environmental concerns about the unintended consequences of the oil sands industry are linked to environmental issues in the rest of Canada. While pipelines are considered to be the most efficient ...

According to Intergovernmental Panel on Climate Change (IPCC) and other energy organizations "there is more than twice as much carbon in the tar sands oil" than in conventional oil. Hansen argued that coal, tar sands, and tar shale should not be used as energy sources because of their carbon emissions and claimed that the completion of the ...
