|    And still more facts about Alberta's tar    |

      XPost: can.politics, ab.politics, bc.politics       XPost: ont.politics       From: ConsRCons@govt.cda              Posted on March 7, 2009       The Facts About the Alberta Tar Sands                     In Canada, both the governing Conservatives and the opposition Liberals       are trying to shrug off National Geographic magazine’s recent       photographic expose of the massive devastation caused by mining the       Alberta Tar Sands. Facts just don’t matter if they might undermine profits.              Both of Canada’s major party leaders are defending the continuance and       further development of the Alberta Tar Sands by saying that carbon       capture and storage (CCS) will collect carbon dioxide emissions from Tar       Sands operations and make them environmentally and socially sustainable.       Both leaders know that this technology is currently not available and       that, if successfully developed, it will be very costly and “the first       commercial CCS plant won’t be on stream until 2030 at the earliest” [MIT].              Also not addressed is the vast technological difference between CCS for       coal and CCS for Tar Sands, the latter being so much more complex       because of the number and diversity of emission sources and locations.              As well, when speaking about the Tar Sands, our leaders do not address       the loss of more of our boreal forest and its biodiversity and carbon       sequestration values, which is already providing extensive natural       carbon capture and storage. Our leaders also play only minor homage to       the development of renewable energy, which does not require any carbon       capture and storage.              Greenhouse gas emissions:               - The Alberta Tar Sands are the fastest growing source of greenhouse       gas emissions in Canada and stand as the single greatest obstacle to       Canada meeting its global climate change responsibilities.              - Producing a barrel of Tars Sand oil emits three times more       greenhouse gases than producing a barrel of conventional oil, making Tar       Sands oil some of the dirtiest on the planet.              - If current development plans proceed, by 2020 the Tar Sands will       release twice as many greenhouse gases as are currently produced by all       the cars and trucks in Canada.              - As one of the largest, most intact old-growth forests left on       Earth, containing more carbon per hectare than any other ecosystem, the       boreal forest provides ecosystem services that are globally important in       mitigating climate change. The more forest disturbed for the Tar Sands,       the more stored carbon released.              - In order to prevent catastrophic consequences from global warming,       developed countries are required to reduce their carbon dioxide       emissions to 25%-40% below 1990 levels by 2020. The Conservative       federal government’s emissions plan calls for a reduction of 20% below       2006 levels by 2020, which is equivalent to an increase of 2% over 1990       levels.              Resource usage:              - Two tons of oil sands are needed to produce one barrel of oil       (roughly 1/8 of a ton). Just one of the four operating mines in Alberta       has excavated more soil than the Great Pyramid of Cheops, the Great Wall       of China, the Suez Canal and the world’s 10 biggest dams combined.              - Tar Sands extraction utilizes enough natural gas to heat over 3       million homes in Canada. Its rapid depletion of natural gas is not only       hastening the return to coal for domestic heating and power generation,       but it is also driving Canada’s so-called nuclear renaissance. Canada       may well become the first nation to use nuclear energy not to retire       fossil fuels, but to accelerate their exploitation.              - 2 to 4.5 barrels of water are used to produce each barrel of oil.       Every day, Canada exports one million barrels of bitumen to the United       States and three million barrels of virtual water.              - Tar Sands operations are currently allowed to draw 349 million cubic       metres of water per year, twice that utilized by the city of Calgary. An       estimated 82 % of this water comes from the Athabasca River, which is       already facing loss of glacial water from the Colombia Ice Fields due to       global warming.                     Environmental concerns:              - Industrial development of the scale of the Alberta Tar Sands could       push the boreal ecosystem over its tipping point and lead to       irreversible ecological damage and loss of biodiversity.              - About 90% of the water used to process the Tar Sands ends up in       acutely toxic tailing ponds that line the Athabaska River and threaten       the health of the whole river basin. For every barrel of oil extracted,       six barrels of tailings are produced.              - According to a recent Environmental Defense report, the ponds are       already leaking over 11 million litres a day of contaminated water into       the environment.       Should proposed projects proceed on schedule, 2012 would see a five-fold       increase, to over 25 billion litres a year.              - Tailing ‘ponds’ cover more than 50 sq km and can be seen from       space. One tailings pond at Syncrude’s mining operation is held in check       by the third-largest dam in the world.              - Tailing ‘ponds’ are so toxic that propane cannons are used to keep       ducks from landing on them. Regardless, they result in over 8,000 oiled       and drowned birds annually and in one incident last April, 500 ducks       died after landing on one of Syncrude’s ponds, which did not have       noisemakers set up.              - A recent report estimated that, because the Tar Sands belt is on the       migratory route of North American ducks and other waterfowl, over the       next 30 to 50 years, as many as 166 million birds could be lost, due to       loss of breeding areas and from birds landing in tailing ponds of waste       that look like real bodies of water.              - Canada has no national water policy and one of the worst records of       pollution enforcement of any industrial nation.              - Because of the effects of global warming, intact northern forest       ecosystems will become very important to the forest birds and wildlife       that will need to migrate northward in order to survive.              - Addition to the already massive pipeline network that exists, Tar       Sands development plans include pipeline expansions and additions from       northern Alberta into the U.S., and to B.C. The latter could see the       building of a supertanker port in Kitimat and oil tankers exporting oil       via the Inside Passage of northern B.C. waters.              - A recent recommendation from the Cumulative Environment Management       Association (CEMA) asking for a freeze until 2011 on sales of mineral       rights in an area marked for conservation was rejected by the Alberta       government. CEMA’s members represent government agencies, environmental       groups, aboriginal communities and around 30 oil companies.
