Dirty Tar Sands

Canada’s tar sands are the dirtiest environmentally of any form of oil extraction. They massively pollute land, water and the global atmosphere with greenhouse gases. The problem is huge quantities of super heated steam from natural gas are needed to heat the tar sands up enough for the bitumen in them to melt and flow. You get greenhouse gas emissions from the natural gas burning, creating the energy used to pump the viscous tar, creating the energy to refine the tar and when the oil/gasoline is finally burned. The steam condenses and the oily slurry is dumped into nearby rivers. However, despite these environmental drawbacks, the USA projects it will get most of its oil from the Canadian tar sands in 2012. Canadians have no choice in the matter.
