IMO second half of the talk goes off the rails.
Goes on an environmental rant at about minute 15, anti-oil sands, anti-Canadian energy etc. He feels strongly that an environmental disaster is coming and therefore his rhetoric is much more condemning and urgent.
I am not ready to put the environment at the top of my policy preference list, I think we have other more pressing issues like inequality.
Driving the cost of energy up for the poor at this time doesn't seem like it would be helpful.
