tar sands oil
At least 500 water protectors have been arrested protesting the Line 3 pipeline, which will carry toxic tar sands oil from Canada into the U.S.
The pipeline spilled half an Olympic-sized swimming pool's worth of particularly dirty oil into North Dakota's wetlands.
Despite their costly environmental impacts, oil spills like the recent one in South Dakota weren’t a factor in the decision to approve the Keystone XL.
An oil spill in South Dakota that leaked thousands of gallons of highly polluting oil could damage the environment more than the company has let on.
