Cons: 1. The threat to wildlife: Waste products from oil sands are highly toxic 2. Limited reserves: The oil sand reserves are limited. 3. Emission of greenhouse gases: Oil sands are too deep and the extraction 4. Affects ecosystem: Clearing of trees, brush, topsoil and clay on oil sand Pros and cons: Alberta oil sands. A scientific panel said Tuesday that weaknesses in measuring pollution from the Alberta oil sands must be corrected. Pollution is one argument against the oil sands development. Global News takes a look at the pros and cons involved in developing the oil sands. Pros & Cons of Oil Sands Summarized by Walter Sorochan, Posted 2009 Updated February 10, 2011. There is controversy about the development of oil sand regions in the Canadian province of Alberta. There are major concerns about pollution of the environment, pollution of the Athabasca river, high incidence of cancer among indigent people in the Cons: -As far as extraction methods go, the ones used in the Alberta oil sands are among the most carbon-intensive. Cons Enormous GHG emissions. Oil sands are already Canada’s largest source of CO2 emissions. Relatively low net energy return compared to other sources Oil sands require too much water to be sustainable. Oil sands require about 4 barrels of water for every one barrel extracted. This is far too much, is a strain on local water resources, is costly, consumes significant amount of energy in the piping of the water, and leaves polluted ponds behind. 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. Although some steps are being taken to reduce the severity of these impacts - such as reclamation - there are still associated climate, air, water, and other ecological effects.

It isn’t just the companies and governments that can profit from oil energy, but there must be enough money available to make an investment for individuals to get involved. What Are the Cons of Oil Energy? 1. By definition, oil energy is a finite resource. There are vast fields of oil to harvest. Tar sands and shale can provide oil as well.

The Alberta Tar Sands, located in northern Canada, contain the largest deposits of bitumen oil in the world. The tar Tar Sands Oil: Pros and Cons. Stember, D. Mining Tar SandS for Crude. Tar sands are composed of clay, sand, water, and bitumen (a heavy black hydrocarbon). Extracted bitumen can be refined into Oil shale and tar sands occur in dozens of countries around the world. With in- place pros and cons to each, but at the moment there is insuffi- cient diluent to Here in Canada, the tar sands are huge deposits of bitumen, a tar-like substance that's turned into oil through energy-intensive processes that pollute rivers, lace

Oil sands require too much water to be sustainable. Oil sands require about 4 barrels of water for every one barrel extracted. This is far too much, is a strain on local water resources, is costly, consumes significant amount of energy in the piping of the water, and leaves polluted ponds behind.

22 Sep 2009 Most of the Canadian oil sands are located in Alberta, with 175 billion barrels of recoverable bitumen underlying approximately 140,800 square To date, the pros and cons of oil sands development in Alberta have not been evaluated by comprehensive cost-benefit analysis (CBA). In this paper we present To view the Alberta oil sands from south of the U.S.-Canada border one must Weighing the pros and cons of oil-sands development depends largely on the 1.4 Benefits of Tar Sand Production.

I once lamented about the poor quality of the oil sands. It has a low specific gravity, is mixed with silt, sand and brackish water, is located under swampy terrain that sees temperatures as cold Cons-As far as extraction methods go, the ones used in the Alberta oil sands are among the most carbon-intensive. When compared to the average crude oil processed in the United States, greenhouse gas emissions from the Alberta oil sands are approximately five to 15 per cent higher because the oil is too deep to be extracted using traditional
