Canada wanted to send the dirtiest oil on the planet through the heart of America so that they could access export routes. And they proposed getting there by bringing the pipeline right over the Ogallala Aquifer, one of America's most important repositories of fresh water. Along the route, Democrats and Republicans alike opposed it.Nocera never mentioned that a first pipeline just like the proposed Keystone XL, built by the same foreign company, TransCanada, had over 12 spills in the U.S. (30 if you count Canada) in just its first year of operation. Some of those spills have yet to be cleaned up.
