The reality is, left-tards would rather financially support Islamic terrorism by buying oil from Saudi Arabia, rather than use nice, blood-free oil from Canada.
Not to mention the roughly 65,000 liters of nasty, filthy bunker fuel burned by the average Suezmax supertanker in the course of a day at sea.
For those unfamiliar with bunker fuel, it has 2000 times the sulphur content of diesel fuel and has been banned for use on land by just about every country on Earth.
And that's just the tip of the iceberg. All this globalization has hugely increased the amount of marine traffic. One detailed study even goes so far as to suggest the 16 largest ships in the world, a combination of supertankers and container ships, generate as much emissions and particulate as all the cars on the planet. And at a price that's literally pennies on the gallon, there's not much incentive to stop using bunker fuel.
Ironic isn't it? We've sent many of our good paying jobs overseas to countries with significantly less stringent environmental controls if any, all so large numbers of ships can crank out the emissions bringing us cheaply made crap that we used to make here with some semblance of quality.
Once again, Canada as a nation of 35 million people generates only HALF the annual emissions that international shipping does but the morons in charge want to slit our throats over it like we're the big, evil destroyers of planet Earth or something.
