Anti-pipeline protesters say: "Pipelines leak constantly" and "I am denying Native Americans clean ground water" and "I am a troll for big oil". They then listed a slew of pipeline leaks that have happened over the past 100 years.
I don't think they are going to understand the precision with which things are monitored with modern tech, or care that the Keystone pipeline is required by law to have leak detection with automatic shut off valves at intervals along the length of the pipeline. This is not the 1800's, the Keystone pipeline is likely to have such advanced leak monitoring that sensors along the pipeline will be able to listen for leaks, detect pressure changes a leak would cause, do mass measurements to detect leaks and then automatically shut the pipeline down without human intervention, all the while they are installed on a pipeline made with far greater precision and spec than anything that was around 100 years ago. They won't care that there are plenty of 100 year old pipelines that continue to operate problem free.
I challenge the trolls to prove where a pipeline did significant damage anywhere in the region the Keystone pipeline is going. It is not a seismic zone. Anyway, the point is moot. Because what we are dealing with is communism, from an outside influence (probably China) doing all it can to stop America from receiving what is needed to compete against them. Any time a snail, or weird species we have never heard of is "endangered by _______" or that the Indians are going to be destroyed by something they can't even see and would never know was there if they were not told, every time a poor lowly group has been made the victim all the while they have been handed huge advantages, suspect ONE THING: A communist with an agenda that can ride on the backs of "victims" until it comes to fruition.
