North Dakota pipeline

Recently president Donald Trump re-enacted the plan to build a pipeline for oil through North Dakota. Native Americans and conservationists are very opposed to this deal fearing it may have a catastrophic effect on the environment. If built properly It simply would be a pipeline for oil to travel through and would not be of too much harm to the environment. The main issue I see is that some freelance eco-terrorist would try to blow it up, full of oil, the effect on the environment would be catastrophic.
