I have a lot of questions, actually, about this because it is an intriguing and interesting area for all of us and for our future, obviously. I have children and grandchildren. I think a lot of us are concerned about the possible dumping of mercury. There is some intimation of storage and so on here, but we sure don't want this in landfills. I would be rather pleased to have people in at this committee, or at some future point on a private member's bill, to hear more about that, because I think there are issues of safety and security and storage.
Carol, you've responded in part. Again, the comparison was made to coal-fired plants as opposed to hydro or whatever. That was the math used to explain why we'd be better ahead on that equation on the mercury scale, using coal-fired plants. But those are not the only kinds of power plants that are used in the country, of course.
Do you have any comments beyond saying we do need more study on this? Do you buy the math that was offered here? Is that something you've heard of before, in terms of the calculation that Mr. Dewar gave just moments ago?
