This is a textbook case of environmental racism. The original route of the Dakota Access Pipeline took it close to Bismarck, North Dakota which happens to be about 95% white. Those citizens protested, so the pipeline was rerouted through sacred tribal burial grounds, and across the main drinking water supply for the Standing Rock Sioux. The private interests building the pipeline have already bulldozed several tribal burial grounds, in violation of federal treaties.

But regardless of its previous promises, the government is refusing to protect the lands and the health of native people when it conflicts with the interests of others. Treaties and promises once again mean nothing. This is literally the oldest story in the America.
