I'm no environmentalist but Mason is wrong in several ways.
  Most important, if we need to stop ugly things poison for the planet "some day", obviously the sooner  we stop them, like now, for example, the better.

  If the Vietnam War was dead wrong in 1967, 68, 69 or 73, it was wrong in 1964. By logic, the Vietnam War should have been stopped in 1964. Jane Fonda was one of the first famous folks to call for a halt to it; now she is one of the famous calling for a stop to the tar sands. Bravo Jane Fonda!

The jobs that will be lost are unfortunate. But folks with high tech skills can always find another job. But nobody worries about good manufacturing jobs making useful products being sent overseas; so why worry about jobs lost in the ugly tar sands?  Makes no sense. It only makes profits for the oiligarchies.

Another point is there's a daily agenda by mudstream media to maintain the corrupt status quo. They do this by demonizing the rebellious like Fonda and Trump in the same bag.
