Amidst all of this political and social jostling to be heard by the greens,  the facts regarding our use of fossil fuels are lost.  All of us, most especially the greens, need to understand that the worlds daily consumption of crude oil is 91 million barrels.  Tomorrow the same, and the day after that and so on.  Nearly all of it moves by pipeline, the safest land-based means of moving it, and by tanker, the only means of seaborne transport.  It's an out of sight out of mind deal for those who stomp their little feet when they don't get their way.  
Our lifestyles are only possible with cheap, reliable, and safe energy, and fossil fuels provide 90% of it.  
Here in Victoria I am amazed at those who hold signs stating "No Tankers".  I fire up my MarineTraffic app on my phone and show them in real time where the tankers are, and always have been, transiting to Vancouver and Washington State.  
It's how we live, and Mayor Robertson, and Weaver, and May, are disconnected from reality.
