	<onlyinclude>The '''environmental impact of the [[oil sands]]''' is an issue that has been extremely divisive. As with the extraction and use of any [[fossil fuel]], negative environmental effects arise as a result of the extraction, [[bitumen upgrading\|upgrading]], and processing of [[bitumen]] from the oil sands.</onlyinclude> Although some steps are being taken to reduce the severity of these impacts - such as reclamation - there are still associated climate, air, and ~~water~~ effects. Since there are so many environmental impacts that can be discussed, the main concerns have been broken down into several core issues including:		[[Category: Rudi grade Ashley edit]]

Since there are so many environmental impacts that can be discussed, the main concerns have been broken down into several core issues including:

	* '''[[Oil sands tailings ponds\|Tailings Ponds Impacts]]''': Tailings ponds are settling ponds that contain the waste byproduct of oil sands extraction and upgrading. They are a mix of water, sand, silt, clay, unrecovered hydrocarbons, and other contaminants.		* '''[[Oil sands tailings ponds\|Tailings Ponds Impacts]]''': Tailings ponds are settling ponds that contain the waste byproduct of oil sands extraction and upgrading.

	* '''[[Water impacts of oil sands\|Water Impacts]]''': The extraction of bitumen from oil sands requires a large amount of water, and thus water use is a concern when looking at oil sands extraction. Water used in the oil sands can be recycled, but only small amounts of this water are returned to the natural cycle.		* '''[[Water impacts of oil sands\|Water Impacts]]''': The extraction of bitumen from oil sands requires a large amount of water, and thus water use is a concern when looking at oil sands extraction. Water used in the oil sands can be recycled, but only small amounts of this water are returned to the natural cycle.
	* '''[[Air pollution from oil sands\|Air Quality Impacts]]''': Along with greenhouse gases, other pollutants are released into the air during oil sands operations. These pollutants are harmful to the environment and human health, and include gases such as [[NOx]] and [[SOx]].		* '''[[Air pollution from oil sands\|Air Quality Impacts]]''': Along with greenhouse gases, other pollutants are released into the air during oil sands operations.

The chemicals in the tailings are ~~factor~~ that can make reclamation difficult.		* '''[[Oil sands land reclamation\|Reclamation]]''': Reclamation is the attempt to return previously used land - whether it was used for surface mining or as a tailings ponds - to their natural state.

* '''[[Climate impacts of oil sands|Climate Impacts]]''': The greenhouse gas emissions for oil sand extraction and processing are significantly larger than for conventional crude oil. These emissions contribute to global warming and the enhanced greenhouse effect.
