One minute, okay. I'll make this question fairly quick, then, for Mr. Stringham.
We heard a reference from the folks at Pembina Institute that two-thirds of the acids need to remain in the ground to avoid catastrophic climate change. What kind of diversification is going on within the oil sands for distribution? Is that a fair assessment? Do we have to leave two-thirds in the ground, or are we working on technologies today that are going to allow transportation and access to diversify it in a safe, clean way?
