Environmental impact of oil sand extraction

Sand mining: the global environmental crisis you’ve probably never heard of Cities From Cambodia to California, industrial-scale sand mining is causing wildlife to die, local trade to wither and Environmental impacts from fossil fuel pollution are rapidly increasing in regions that have the highest concentrations of fuels. There are multiple effects of mining fossil fuels. Drilling and mining practices take a substantial toll on local water sources, biologic life and natural resources.

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, upgrading , and processing of bitumen from the oil sands. The environmental impacts of oil sands extraction are already apparent in places where production is already occurring. Thus areas containing oil sands can expect marked changes in terms of land cover and freshwater appropriations in the near future. This expected escalation in oil sands extraction may therefore alter the existing equilibria in There are two primary extraction methods for oil sands: open-pit mining and in-situ mining. The technique used depends on the depth of the deposit. For example, in-situ mining is used when bitumen lies too deep beneath the surface for open-pit mining. Injection of steam is used in both methods to heat the bitumen, Mining extraction currently accounts for 60% 6 of the 1.4 million barrels of bitumen produced each day. 7 In situ development represents the most significant growth potential for the oil sands industry and will contribute a growing proportion of future oil sands production. While the oil sands industry continues to make technological advances, annual production growth presents challenges to land, water, and air impacts, and energy conservation. Through its CanmetENERGY laboratories, Natural Resources Canada is committed to supporting the development of technological solutions to help drive improved environmental Environmental Impacts of Oil Extraction While extracting oil has many effects on the environment, not all of them are bad. After a deep-sea well is no longer profitable, the well is plugged, and the rig turned over, allowing it to become a reef. These reefs become home to a variety of marine organisms.

Tar sands are extracted by either surface (open pit) mining or in-situ extraction. tar sands have been shown to generate considerable environmental impacts
