Thank you, Mr. Chair. I have just a couple of questions.
Professor, I was interested to hear you say that some of your students may be taking a little bit longer to find jobs but they are finding jobs. I was at a professionals' employment summit in Calgary a couple of weeks ago. It was more geared toward the oil and gas sector. There were petroleum engineers, geoscientists, and geologists. Many of them haven't had jobs in two years. For them, they don't see a light at the end of the tunnel. In the commodities, oil and gas and mining, we've gone through these ups and downs over the years, but this is the first time many of them are saying that they don't see an exit and that this is the worst they've ever seen it. There are just so many things going against them. So to your students, I hope things work out well.
My question, just really quickly, is on water. I see that your expertise is on the water side, and that's something we have to focus on a great deal. What would be the water consumption innovations, I guess, to minimize water impact in mining as compared with, let's say, coal, nuclear, or oil and gas? In the oil sands, we got rid of tailing ponds for the most part. What are the innovations and advancements for water conservation in the mining sector?
