Proposed Tar Sands Oil Pipeline Elicits Protests

The proposed Keystone XL pipeline could carry crude oil some 1,700 miles from Alberta, Canada, to the Gulf Coast in Texas. The State Department released a "Final Environmental Impact Statement" on the project, which is also known as the "tar sands" pipeline because of the kind of oil it would transport, late last week.
Several environmental groups, including the Natural Resources Defense Council and National Wildlife Federation, joined together to release a major report of their own in February of this year on the safety risks of the pipeline.
At organized sit-ins in recent weeks, demonstrators gathered at the White House to voice their objections to the controversial pipeline, citing concerns over the environmental impacts of the $7 billion proposal. If it is implemented, oil imports from Canada would be doubled.
Among the concerns of environmentalists is the possibility of erosion in the pipeline due to the more corrosive substance, the creation of waste ponds and strip-mining operations in Alberta.
But advocates say with instability in oil-producing nations in the Middle East, the pipeline would provide a more reliable supply.
