An editorial in today's Washington Post is calling crude oil from Alberta oilsands ``nasty'' but it says that's no reason to kill a proposed pipeline to carry the oil to Texas. The newspaper says legislators in the U.S. should vote in favour of the proposed Keystone X-L pipeline. It says with or without it, oilsands crude will find its way to the U.S.  The nenwspaper says the best way to reduce emissions from the oilsands is for the U-S government to concentrate on reducing America's appetite for oil.
