Is it in our national interest to overheat the planet? That's the question Obama faces in deciding whether to approve Keystone XL, a 2,000-mile-long pipeline that will bring 500,000 barrels of tar-sand oil from Canada to oil refineries on the Gulf of Mexico.
Keystone will deliver 830,000 barrels of oil per day from Canada, North Dakota, and Montana to Gulf Coast refineries.
Keystone would allow us to transport 700,000 barrels of oil a day from our northern neighbor Canada to refineries in the United States.
If Canada could simply apply the basic principles of sustainable development, such as the internalization of costs and 'polluters pay,' it would have long-term beneficial effects, both environmental and economic.
I used to live in Canada. It's a beautiful country with a lot of different kind of topographic regions.

We know that trade, NAFTA, the free and open trade between Canada and the U.S. creates millions of good jobs on both sides of the border.
I think of Canada, first and foremost, in terms of space. The amount of space available is breathtaking.
Canada evolved within the British Empire: it inherited the Parliamentary system, the Cabinet system and all the other features of the British constitutional system which had been in place, for the most part, for several centuries before Canada was even thought of.
I do not consider divorce an evil by any means. It is just as much a refuge for women married to brutal men as Canada was to the slaves of brutal masters.
In Canada, anything that's not in the city is referred to as a cottage. Or a log cabin.
It is incomprehensible that drug companies still get away with charging Americans twice as much, or more, than citizens of Canada or Europe for the exact same drugs manufactured by the exact same companies.
I tour as many countries as possible, and I've toured every state in America, plus every province in Canada.
If the national mental illness of the United States is megalomania, that of Canada is paranoid schizophrenia.
Everything that comes out of Canada musically, I support. I support Toronto 100% because I'm on the side of the music.
Canada is the essence of not being. Not English, not American, it is the mathematic of not being. And a subtle flavour - we're more like celery as a flavour.
