... we should be resisting any and all modalities of future fossil fuel exploitation. who cares if pipelines are "safer" when we know that there is no planet-safe way to burn the oil they carry. if pipelines are the most efficient way to move the resource of oil, we need to be preventing their deployment because oil will kill us if we let it.
we're in the midgame of climate change... better to take radical action to prevent the worst possible end case.
