It is stopping the tar sands.

And most controversially, it means the tar sands.

The Alberta government and the oil companies that influence it would upgrade tar sands to oil sands, apparently thinking that a better name somehow silences environmental critics. Environmentalists opposing the pipeline refer, with equal deftness, to dirty oil.

So this is where the tar sands live, under one of the last magnificent Boreal forests.

And still, those extreme environments are very good places if we want to stop the shifting sands.

And geriatricians try to hold back the sands of time by stopping the damage converting into pathology.

The turbulent sands above our heads, the flinging of our swords... they're naught but falling stars in the night sky.

I won't be taking you to the high Arctic, the life of the Inuit, or to the searing sands of the Sahara.

Okay, so first of all, let's welcome Mr. Jamire Williams on the drums, Burniss Travis on the bass, and Mr. Christian Sands on the piano.

They don't like fighting over oil, they don't like being in the sands and they don't like where the oil money goes and what sort of instability it creates.

Whole cities are rising out of desert sands overnight. China is building more roads, airports, and bridges every five years than Europe and the US combined build in 20.

I'm always surprised by how little people outside of Canada know about the Alberta Tar Sands, which this year are projected to become the number one source of imported oil to the United States.

Junkies find veins in their toes when the ones in their arms and their legs collapse. Developing tar sands and coal shale is the equivalent. Here are just a few of the investments that I personally think make sense.

The geriatrician will intervene late in the day, when pathology is becoming evident, and the geriatrician will try and hold back the sands of time, and stop the accumulation of side effects from causing the pathology quite so soon.

You've heard so much about the developments of the tar sands, the controversy about the Keystone and the Enbridge pipelines, but these are just elements of a tsunami of industrial development that is sweeping across all of the wild country of northern Canada.

The latest figures show that the old model is not working. There are a lot of great investments that you can make. If you are investing in tar sands or shale oil, then you have a portfolio that is crammed with sub prime carbon assets.

Those true believers argue that America s consumers can long pursue their spendthrift ways because their country s economy is better than everyone else s. The US labor market is more flexible than Europe s, enabling it to react more nimbly to the ever shifting sands of globalization.

EDMONTON Calm discussion of the environment nowadays is about as plausible as reasoned dialogue on witchcraft in colonial Massachusetts. Consider the hyperbolic debate over the Keystone XL pipeline, which would funnel oil from Canada s Athabasca tar sands in northeastern Alberta to refineries on the Texas Gulf Coast.

This will require massive investments in new technologies and resources, not a fight to the finish over Middle East oil. Important energy technologies will include conversion of coal to liquids (such as gasoline), use of tar sands and oil shale, and growth in non fossil fuel energy sources.

A NAFTA 2.0 could focus on areas that were originally excluded, such as labor mobility and energy. The development of Canadian oil sands, the shale energy revolution in the US, and the opening of Mexico s oil sector to foreign investment imply the biggest geopolitical shift since the collapse of communism.

Second, the world s citizens do not want to go down in flames. Public opinion has so far succeeded in blocking the construction of the Keystone XL Pipeline, which would accelerate the production of Canada s oil sands a shocking prospect, given that neither Canada nor the US yet have committed to a climate plan.

But instead of placing a rising fee on carbon emissions to make fossil fuels pay their true cost to society, our governments are forcing the public to subsidize fossil fuels by 400 to 500 billion dollars per year worldwide, thus encouraging extraction of every fossil fuel mountaintop removal, longwall mining, fracking, tar sands, tar shale, deep ocean Arctic drilling.

This double whammy can be mitigated only by innovative water management and conservation, and by developing nontraditional supply sources. As in the oil and gas sector where tapping unconventional sources, such as shale and tar sands, has proved a game changer the water sector must adopt all unconventional options, including recycling wastewater and desalinating ocean and brackish waters.

These are the Athabasca tar sands, and there's an enormous amount first of mining, the largest trucks in the world are working here, and then you've got to pull out this black sludge, which is basically oil that doesn't flow. It's tied to the sand. And then you've got to use a lot of steam to separate it, which only works at today's oil prices.

Ethnographer Wade Davis explores hidden places in the wider world but in this powerful short talk he urges us to save a paradise in his backyard, Northern Canada. The Sacred Headwaters, remote and pristine, are under threat because they hide rich tar sands. With stunning photos, Davis asks a tough question How can we balance society's need for fuels with the urge to protect such glorious wilderness?

At the Headwaters itself, Shell Canada has plans to extract methane gas from coal seams that underly a million acres, fracking the coal with hundreds of millions of gallons of toxic chemicals, establishing perhaps as many as 6,000 wellheads, and eventually a network of roads and pipelines and flaring wellheads, all to generate methane gas that most likely will go east to fuel the expansion of the tar sands.

In North America, the shale energy revolution in the US, Canada s oil sands, and the prospect of more onshore and offshore oil production in Mexico (now that its energy sector is open to private and foreign investment) have made the continent less dependent on Middle East supplies. Moreover, South America holds vast hydrocarbon reserves, from Colombia all the way to Argentina, as does East Africa, from Kenya all the way to Mozambique.

Low prices may already have contributed to delays in America's decision to begin exporting crude oil, as well as to the political viability of US President Barack Obama's veto of the Keystone XL pipeline, intended to transport oil from the Canadian tar sands to the Gulf of Mexico for export. Add to that the delay in the opening of the Mexican energy sector, and it seems that low oil prices could amount to a net gain for the Kingdom.

This is what accumulates in the tar sands of Alberta. These are sulfur blocks. Because as you separate that petroleum from the sand, and use an enormous amount of energy inside that vapor steam to separate this stuff you also have to separate out the sulfur. The difference between light crude and heavy crude well, it's about 14 bucks a barrel. That's why you're building these pyramids of sulfur blocks. And by the way, the scale on these things is pretty large.
