Oil companies really run our government.  We have no say over what risks they create to our aquifers, our land, our history.  Any benefit of these pipelines to the US are temporary at best.  And when they leak, which they eventually will....who will pay to clean it up?  But then our new President is definitely under the influence if not actually financially benefitting from oil company money.  Until our government finds  the guts to stand up to big oil our environment will be at the mercy of oil company greed.
